    The invention relates to a manufacturing system for the production of workpieces from sheet metal by forming in a bending process, in particular by pivot bending or swing bending. Furthermore, the invention also relates to a method for adapting an overall length of a bending edge of a jaw set of a manufacturing system for the production of workpieces from sheet metal by forming in a bending process, in particular by pivot bending or swing bending.
    A bending machine of the generic type has become known from DE 196 35 106 A1. The bending machine comprises a bending beam as well as a first and a second clamping beam for clamping a workpiece. One of the clamping cheeks has interchangeably arranged first and second clamping tool segments of a clamping tool set. A second clamping tool segment is arranged on each side of the clamping tool set, which segment has a sole part that is adjustable relative to this from a clamping position into a retracted position. The disadvantage here is that in order to adjust the clamping length or the bending edge formed by the clamping tool set, individual ones of the first clamping tool segments located between the two externally arranged second clamping tool segments must be removed or added from the clamping tool set. This usually involves extensive retrofitting.
    Another generic bending machine is known from WO 98/53929 A1. The bending machine comprises a bending beam as well as a first and a second clamping beam for clamping a workpiece. One of the clamping cheeks also has interchangeably arranged first and / 39
    N2016 / 049-AT-00 second clamping tool segments of a clamping tool set. The respective second clamping tool segments arranged on the outside each have a sole part which is adjustable relative to their base body from a clamping position to a retracted position. Again, it is disadvantageous that in order to adjust the clamping length or the bending edge formed by the clamping tool set, individual ones of the first clamping tool segments located between the two externally arranged second clamping tool segments have to be removed or added from the clamping tool set.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide a production system and a method by means of which a user is able to carry out a simple and quick assembly of jaw sets for different bending requirements.
    This object is achieved by a production plant and a method according to the claims.
    The manufacturing system according to the invention is used to manufacture workpieces from sheet metal by forming in a bending process, in particular by pivot bending or swing bending. The production plant can include at least the following plant parts or components:
    a bending machine with a fixed machine frame, a lower clamping bar and with an upper clamping bar, at least one of the clamping bars being adjustable relative to the machine frame in order to hold the workpiece to be clamped,
    - A clamping tool with at least one lower jaw and with an upper set of jaws consisting of a plurality of first upper jaws and at least one second upper jaw. Each of the clamping jaws has a base body, the at least one lower clamping jaw being held on the lower clamping bar and the upper clamping jaws of the upper clamping jaw set being held on the upper clamping bar. In the direction of the longitudinal extension of the clamping bars, the at least one second upper clamping jaw has a / 39 at a first end section relative to its base body
    N2016 / 049-AT-00
    Working position in a threading position displaceable first jaw part, wherein in the threading position the longitudinal dimension of the upper jaw set is shorter than in the working position, and
    - A bending edge aligned in the direction of the longitudinal extension of the clamping bar is formed by the upper jaw set when the upper jaws are in the working position, and a first partial bending edge of the bending edge is formed by each first upper jaw and one by the at least one second upper jaw in the working position second partial bending edge is formed, and
    a bending unit, which bending unit is adjustable relative to the clamping tool for carrying out the bending process, and
    - That the at least one second upper jaw further comprises a second jaw part which can be displaced from the working position into the unthreading position on its second end section which is spaced in the direction of the longitudinal extent of the clamping bar, and
    that at least one first upper jaw is arranged on both sides of the at least one second upper jaw in the direction of the longitudinal extent of the clamping bar, and
    - That the first upper jaws each have a first horn at least at their first end regions facing away from the at least one second upper jaw, which first horn is projecting over the respective base body of the first upper jaw in the direction of the longitudinal extent of the clamping bar.
    The advantage achieved thereby is that the provision on both sides of the jaw parts which can be displaced relative to the base body from the working position to the unthreading position creates an adjustment space between the first upper jaws arranged on both sides thereof and the second upper jaws arranged between them. This makes it possible to easily and quickly adapt the clamping length of the upper tool set to different application conditions. Since the first upper jaws are each provided with an additional horn on the outside of the jaw set, the clamping length or the total / 39
    N2016 / 049-AT-00 length of the bending edge to be formed can be done by simply adding or removing the first upper jaws from the side. The second clamping jaw always remains in an unchanged position with respect to the clamping bar. Before the start of the clamping process of the workpiece to be manufactured, the upper jaw set must be shifted to its shortened unthreading position and before the beginning of the clamping process must be adjusted to the extended working position within the workpiece to be manufactured. For this purpose, the first upper jaws located in the vicinity of the second upper jaw are to be adjusted so far that the relatively displaceable jaw parts can be shifted from their shortened unthreading position to the working position with a larger longitudinal dimension. The adjustment movement to be carried out in the direction of the longitudinal extension of the bending beams can be carried out, for example, by a sliding movement. If the upper jaw set is in its working position, the individual upper jaws can be held in a fixed position on the clamping bar and the clamping process of the workpiece to be produced can be carried out. Once the workpiece has been clamped, the bending process can begin. In this way, it can be found with the shortest adjustment movements carried out centrally with respect to the second clamping jaw.
    Furthermore, it can be advantageous if the jaw parts are each formed with a horn-shaped projection, and a shortened outer longitudinal dimension of the second upper jaw in the direction of the longitudinal extent of the clamping bar is defined by the jaw parts in the unthreading position. In this way, a protrusion of the clamping jaw parts in the direction of the longitudinal extension of the clamping bar in the working position can easily be achieved. Due to the relative displacement of the jaw parts, the horn-shaped attachment can be shifted so far within the outline of the base body that an adjustment space can be created on both sides of the second upper jaw.
    Another embodiment is characterized in that the shortened outer longitudinal dimension of the second upper jaw in the unthreading position / 39
    N2016 / 049-AT-00 corresponds to a maximum length of the base body of the second upper jaw. This makes it possible to be able to place the first upper clamping jaws located on either side of the second upper clamping jaw directly on the base body of the second upper clamping jaw in order to achieve a maximum adjustment path.
    A further possible embodiment has the features that, in the unthreading position, the first upper clamping jaws located on each side of the at least one second upper clamping jaw are each displaced in the direction of the base body of the at least one second upper clamping jaw. In this way, in the outer edge region of the set of clamping jaws, the free space necessary for the threading-out process towards the workpiece, in particular its undercut, can be created.
    A further embodiment provides that at least some of the first upper clamping jaws have at their second end regions facing the at least one second upper clamping jaw each a second horn projecting over the base body in the direction of the longitudinal extension of the clamping bar. This means that the first upper jaws can be used more universally. It is thus possible to dispense with the provision of left and right versions, since first upper jaws of this type can be used both on the left side and on the right side of the second upper jaw.
    Another embodiment is characterized in that the at least one second upper jaw of the upper set of jaws is arranged in a fixed position with respect to the upper clamping bar. Due to the fixed positioning of the second upper jaw, the supply of the same with energy for adjusting the relatively displaceable jaw parts can also be provided in a simply fixed position.
    A further preferred embodiment is characterized in that the at least one second upper jaw is arranged in a central region of the upper jaw set. A symmetrical arrangement / 39
    N2016 / 049-AT-00 of the first upper jaw arranged on both sides of the second upper jaw
    Clamping jaws take place.
    Furthermore, it can be advantageous if the number of upper jaws of the upper jaw set is selected such that in the working position a total length of the bending edge corresponds to a sum of the individual lengths of the first partial bending edges of the first upper clamping jaws plus the length of the second partial bending edge the second upper clamping jaw is formed, and the sum formed in this way corresponds at most to a longitudinal dimension of the clamping length to be supported on the workpiece to be produced. An almost or complete continuous clamping length and subsequently an almost continuous bending edge can thus be provided for the bending process to be carried out.
    Another alternative embodiment is characterized in that the number of upper jaws of the upper jaw set is the same in the working position and in the threading position. Additional manipulation processes, such as the addition or removal of individual ones of the clamping jaws, can thereby be avoided. Furthermore, a faster changeover between the working position and the unthreading position can also be achieved.
    A further possible and possibly alternative embodiment has the features that the clamping tool also has a lower jaw set and the lower jaw set comprises a plurality of first lower jaws and at least one second lower jaw, and that the at least one second lower jaw on both sides in the direction of the longitudinal extent the first and second end sections arranged on the clamping bar each have a first and second clamping jaw part which can be displaced from the working position into the unthreading position. This makes it possible to easily carry out individual adaptation to different bending processes in the area of the lower jaw set.
    / 39
    N2016 / 049-AT-00
    A further embodiment provides that at least one first lower jaw is arranged on both sides of the at least one second lower jaw in the direction of the longitudinal extent of the clamping bar. This in turn allows a central arrangement of the second lower jaw between the first lower jaws arranged on both sides thereof.
    However, the object of the invention can also be achieved independently of this by a method for adapting an overall length of a bending edge of a clamping jaw set of a clamping tool of a manufacturing system for the production of workpieces from sheet metal by forming in a bending process, in particular by pivot bending or swing bending, if at least the following steps be performed:
    - Providing a clamping tool comprising at least one lower jaw and an upper jaw set with a plurality of first upper jaws and with at least one second upper jaw, each of the jaws having a base body. The at least one lower jaw is held on the lower clamping bar and the upper jaws of the upper jaw set are held on the upper clamping bar. The at least one second upper jaw has, in the direction of the longitudinal extension of the clamping bar, a first jaw part which can be displaced from a working position into a threading position with respect to its base body, the longitudinal dimension of the upper jaw set being shorter in the threading position than in the working position, and
    - With the upper jaw set when the upper jaws are in the working position, a bending edge which is aligned in the direction of the longitudinal extent of the clamping bar is formed. A first partial bending edge of the bending edge is formed from each first upper clamping jaw and a second partial bending edge is formed from the at least one second upper clamping jaw in the working position, and
    - Providing a bending unit, which bending unit is relatively adjustable with respect to the clamping tool for carrying out the bending process, and
    - That the at least one second upper jaw is also at its in / 39
    N2016 / 049-AT-00
    Direction of the longitudinal extent of the clamping bar, which is arranged at a distance from the first end section, is provided with a second clamping jaw part which can be displaced from the working position into the unthreading position, and
    that at least one first upper jaw is arranged on both sides of the at least one second upper jaw in the direction of the longitudinal extent of the clamping bar, and
    - That the first upper jaws are each provided with a first horn at least at their first end regions facing away from the at least one second upper jaw, which first horn is projecting over the base body in the direction of the longitudinal extension of the clamping bar.
    It is advantageous in the method steps selected here that the provision on both sides of the jaw parts that can be displaced relative to the base body from the working position to the unthreading position creates an adjustment space between the first upper jaws arranged on both sides thereof and the second upper jaws arranged between them. This makes it possible to easily and quickly adapt the clamping length of the upper tool set to different application conditions. Since the first upper jaws are each provided with an additional horn on the outside of the jaw set, the clamping length or the total length of the bending edge to be formed can be done by simply adding or removing the first upper jaws laterally. The second clamping jaw always remains in an unchanged position with respect to the clamping bar. Before the start of the clamping process of the workpiece to be manufactured, the upper jaw set must be shifted to its shortened unthreading position and before the beginning of the clamping process must be adjusted to the extended working position within the workpiece to be manufactured. For this purpose, the first upper jaws located in the vicinity of the second upper jaw are to be adjusted so far that the relatively displaceable jaw parts can be shifted from their shortened unthreading position to the working position with a larger longitudinal dimension. The adjustment / 39 to be carried out in the direction of the longitudinal extension of the bending beams
    N2016 / 049-AT-00 movement can be done, for example, by a sliding movement. If the upper jaw set is in its working position, the individual upper jaws can be held in a fixed position on the clamping bar and the clamping process of the workpiece to be produced can be carried out. Once the workpiece has been clamped, the bending process can begin. In this way, it can be found with the shortest adjustment movements carried out centrally with respect to the second clamping jaw.
    Furthermore, a procedure is advantageous in which the jaw parts are each formed with a horn-shaped extension, and a shortened outer longitudinal dimension of the second upper jaw in the direction of the longitudinal extension of the clamping bar is defined by the jaw parts in the unthreading position. In this way, a protrusion of the clamping jaw parts in the direction of the longitudinal extension of the clamping bar in the working position can easily be achieved. Due to the relative displacement of the jaw parts, the horn-shaped attachment can be shifted so far within the outline of the base body that an adjustment space can be created on both sides of the second upper jaw.
    A further advantageous procedure is characterized in that the shortened outer longitudinal dimension of the second upper jaw corresponds in the threading position to a maximum length of the base body of the second upper jaw. This makes it possible to be able to place the first upper clamping jaws located on either side of the second upper clamping jaw directly on the base body of the second upper clamping jaw in order to achieve a maximum adjustment path.
    A variant of the method is also advantageous in which the first upper clamping jaws located on each side of the at least one second upper clamping jaw are each displaced in the direction of the base body of the at least one second upper clamping jaw in order to form the threading-out position. In this way, in the outer edge region of the set of clamping jaws, the free space necessary for the threading-out process towards the workpiece, in particular its undercut, can be created.
    / 39
    N2016 / 049-AT-00
    Another procedure is characterized in that at least some of the first upper clamping jaws are provided, at their second end regions facing the at least one second upper clamping jaw, each with a second horn protruding in the direction of the longitudinal extension of the clamping bar over the base body. This means that the first upper jaws can be used more universally. It is thus possible to dispense with the provision of left and right versions, since first upper jaws of this type can be used both on the left side and on the right side of the second upper jaw.
    A procedure is also advantageous in which the at least one second upper jaw of the upper jaw set is arranged at a fixed position with respect to the upper jaw. Due to the fixed positioning of the second upper jaw, the supply of the same with energy for adjusting the relatively displaceable jaw parts can also be provided in a simply fixed position.
    A further advantageous procedure is characterized in that the number of upper jaws of the upper jaw set is selected so that in the working position a total length of the bending edge corresponds to a sum, which sum of the individual lengths of the first partial bending edges of the first upper jaws plus the length of the second partial bending edge of the second upper clamping jaw is formed, and the sum thus formed corresponds at most to a longitudinal dimension of the clamping length to be supported on the workpiece to be produced. An almost or complete continuous clamping length and subsequently an almost continuous bending edge can thus be provided for the bending process to be carried out.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    / 39
    N2016 / 049-AT-00
    1 and 2, a manufacturing system 1 is shown in a highly schematic, simplified representation, which in the present case is designed in particular for the swivel bending or swing bending of workpieces 2 to be produced from a sheet metal. A metallic material is usually used as the starting material, which in its undeformed state can be referred to as a flat material or flat element. In the case of swing bending or swing bending, the sheet to be machined or the workpiece 2 to be manufactured is held clamped by clamping jaws 5, 6 and bent with a bending tool 37 by means of its own bending unit 35, which will be described briefly later.
    In order to hold the sheet to be machined or the workpiece 2 to be clamped, which has an undercut at at least one end of the bending area, it may be necessary to design adjustable sections of clamping jaws 5, 6 or at least to adjust some of the clamping jaws 5, 6 themselves hold or store. In order to shift the preferably upper jaw 6 into a lateral undercut located in the area of the jaws 5, 6 and subsequently to move it out of the undercut again, at least some of the jaws 5, 6 are equipped with an adjustable jaw part, as will be explained in more detail below is described. The workpiece 2 with its left-hand and right-hand undercut is simply indicated in FIG. 1.
    The manufacturing system 1 used in the present case for bending and described in more detail comprises a bending machine 3, in particular a swivel bending machine, which is designed to clamp the workpieces 2 or workpieces to be manufactured from the sheet metal between a clamping tool 4 which is adjustable relative to one another. In the present exemplary embodiment, the clamping tool 4 comprises at least one lower clamping jaw 5, but mostly preferably a plurality of lower clamping jaws 5 and at least one upper clamping jaw 6, but mostly preferably several interacting upper clamping jaws 6. The lower or the lower clamping jaws 5 can also be part of the lower beam and the upper jaw 6 or the upper jaws 6 can also be referred to as part of the upper cheek. Furthermore, it can also / 39
    N2016 / 049-AT-00 still be that the lower jaw 5 is formed continuously from one piece.
    In such a bending machine 3, the coordinate system is basically referred to as the “X” direction, which runs in a horizontal plane and in a vertical orientation with respect to the longitudinal extent of the clamping jaws 5, 6. Thus, this is the direction which also corresponds to the feed direction or the removal direction. The “Y” direction is understood to mean the vertical direction, which thus runs in the height direction of the clamping jaws 5, 6 and furthermore in the vertical direction with respect to the horizontal plane. Finally, the “Z” direction is understood to mean that direction which runs in the longitudinal direction or direction in the longitudinal extent of the clamping jaws 5, 6. The longitudinal extent of a bending edge 45, which is later defined by at least one of the clamping jaws 5, 6, is thus also aligned in the “Z” direction.
    As can be seen better from FIG. 1, a plurality of upper clamping jaws 6 are provided, with a further distinction being made in these between at least a first upper clamping jaw 6A and at least a second upper clamping jaw 6B. At least two pieces, but preferably a plurality, of first upper clamping jaws 6A are provided, which are each arranged on opposite sides with respect to the second upper clamping jaw 6B. The sides arranged opposite one another relate to the longitudinal extent of the second upper jaw 6B in the “Z” direction.
    The at least one upper clamping jaw 6 is arranged above the workpiece 2 to be manufactured on the bending machine 3 and is also held there, in particular clamped, accordingly. The at least one lower clamping jaw 5 is also held, in particular clamped, on the bending machine 3.
    A machine frame 7 of the bending machine 3 comprises, for example, vertically projecting from a base plate 8, spaced apart from one another and oriented parallel to one another, 10. These are preferably connected to one another at their end regions spaced from the base plate 8 by a solid transverse structure 11, for example formed from a sheet metal molded part , Ma14 / 39
    N2016 / 049-AT-00 machine frame 7 is usually a solid component of the bending machine 3, which is preferably fixed on a flat hall floor. The shape shown here has been chosen only as an example for a large number of other possible designs.
    The side cheeks 9, 10 can preferably be approximately C-shaped in order to form a free space for shaping the workpiece 2, a fixed lower clamping bar 13, in particular standing on the base plate 8, being fastened to front end faces 12 of legs of the side cheeks 9, 10 near the floor is. This preferably fixedly arranged and fixed lower clamping bar 13 can also be referred to as a clamping table or a lower beam, on which parts of the clamping tool 4 are arranged and also held thereon.
    On front end faces 14, an upper clamping bar 16, in particular a pressure bar, which is relatively adjustable with respect to the lower clamping bar 13, is mounted in a manner in the clamping bar guides 15 on the legs removed from the base plate 8. The clamping bar guides 15 are mostly designed as linear guides in a wide variety of embodiments. The upper clamping bar 16 can also be referred to as the upper cheek, which, however, is guided on the machine frame 7 such that it can be displaced relative to it. Clamping jaw receptacles 19, 20 for fitting with the clamping tool 4 or the clamping tools 4 can be arranged on mutually opposite, mutually facing and mutually parallel end faces 17, 18 of the two clamping bars 13, 16. The one or more clamping tools 4 can also be held on the clamping jaw receptacles 19, 20 with the interposition of an adapter, not shown. Furthermore, it is still possible to hold at least some of the clamping jaws 5, 6 displaceable relative to the respective clamping bars 13, 16 on them in the “Z” direction and clamped in a predetermined position.
    The bending machine 3 shown has, as a drive arrangement 21 for the adjustable upper clamping bar 16, namely the pressure bar, at least one drive means 22 which is preferably operated with electrical energy and which can be connected to a control device 24 fed from an energy network 23.
    / 39
    N2016 / 049-AT-00
    The operation of the bending machine 3 can be controlled, for example, via an input terminal 25 which is connected to the control device 24.
    The drive means 22 are preferably electric motor-operated spindle drives 26, as are generally known, of which adjusting means 27 for a reversible adjusting movement of the upper clamping bar 16 formed by the pressure bar are, for example, drive-connected to the latter. However, other drive means 22 known from the prior art, such as e.g. Cylinder-piston arrangements, stepper motors, rack drives or the like can be used.
    Further details required for the operation of such a bending machine 3, such as, for example, safety devices, stop arrangements and / or control devices, are dispensed with in the present description in order to avoid an unnecessary length of the description.
    Furthermore, it is shown here in a simplified manner that the two clamping bars 13, 16, in particular their tool holders 19, 20, or the clamping tool 4 held thereon with its or its lower and upper clamping jaws 5, 6, when viewed in the longitudinal direction of the clamping bars 13 , 16 define an adjustment plane extending therebetween or a machine plane 28.
    The adjustment plane or the machine plane 28 preferably runs centrally with respect to the clamping bars 13, 16 or the clamping jaw receptacles 19, 20 arranged thereon. In the present exemplary embodiment, a vertically oriented plane is understood here. The adjustment plane or the machine plane 28 can also be referred to as the reference plane for the bending tool 37 located in its vertical orientation. The machine plane 28 can also subsequently form a reference plane for a bending tool 37 of a bending unit 35.
    The two clamping jaws 5, 6 form a clamping area 29 between them at ends that face each other. Mutually facing lower and upper clamping surfaces 30, 31 of the two clamping jaws 5, 6 are preferably aligned at right angles with respect to the adjustment plane or the machine plane 28. This / 39
    N2016 / 049-AT-00
    Clamping surfaces 30, 31 serve to keep the sheet metal, depending on its wall thickness, clamped in a fixed position between the two clamping jaws 5, 6 for carrying out the bending process.
    An additional support table 32 with its support surface defining a support plane 33 can preferably be arranged in the region of the front of the bending machine 3, which is only indicated in a simplified manner in FIG. 2. The support table 32 can be provided, but need not necessarily be present.
    The support level 33 can also be referred to as the support level. It should be mentioned that the support surface does not have to be formed over the entire surface, but can also be formed from a plurality of support partial surfaces arranged next to one another and / or one behind the other in the feed direction of the sheet to be processed. The support surface defined by the support plane 33 is preferably arranged in the same plane as the lower clamping surface 30 of the at least one lower clamping jaw 5. In the case of large-area sheets, this can serve as additional support in the feed area of the bending machine 3 in order to prevent unintentional kinking, particularly in the case of thinner sheets to avoid.
    A bending area 34 is understood to mean that area which serves to form the workpiece 2 to be produced from the mostly flat surface of the undeformed sheet or to further process an already pre-deformed workpiece 2 by forming at least one additional bend or bend.
    The bending area 34 is usually spaced from the machine plane 28 of the clamping beams 13, 16 and is formed by mutually facing end sections of at least one clamping jaw 5, 6, but preferably both clamping jaws 5, 6. In the present exemplary embodiment, the bending region 34 is arranged on the side of the clamping beams 13, 16 facing away from the support table 32 or an operator (not shown in detail). The bending region 34 is thus arranged to run within the machine frame 7.
    / 39
    N2016 / 049-AT-00
    The bending area 34 usually forms a preferably straight bending line on the workpiece 2 to be produced, legs being formed on both sides of the bending area 34 as a result of the bending process carried out. One of the legs of the workpiece 2 is held in a clamping position between the two clamping surfaces 30, 31 of the clamping jaws 5, 6, the at least one further leg being arranged outside the clamping surfaces 30, 31. Depending on the desired or to be produced geometry of the workpiece 2, the two legs enclose a bending angle between them. This bending angle is measured in a reference plane aligned perpendicular to the bending line. For its part, the reference plane is also preferably oriented with respect to the machine plane 28 in the direction perpendicular to it.
    It should be mentioned that the machine frame 7 of the bending machine 3 is only shown in a very simplified manner, it also being possible to use different embodiments. For example, the machine frame 7 or the machine body can be designed with a free stand passage. In this case, the jaw receptacles 19, 20 could be accommodated between the side cheeks 9, 10 or side parts. With a different design of the machine frame 7 or the machine body, no free stand passage is possible, as a result of which the clamping jaw receptacles 19, 20 cannot be received between the side cheeks 9, 10 or side parts.
    To carry out the bending process, the bending machine 3 of the production system 1 also comprises a bending unit 35, which can also be referred to as a bending unit or forming unit. This is indicated in a simplified manner in FIG. 2 and, depending on the bending process to be carried out, can be adjusted relative to the machine frame 7. For the sake of clarity, the illustration of the bending unit 35 and its components has been omitted in FIG. 1.
    In this case, the sheet metal which is pre-positioned and clamped between the clamping jaws 5, 6 can be bent to form the workpiece 2 by means of a bending process, in particular by folding over a surface part with respect to the remaining surface
    N2016 / 049-AT-00 part, along the bending line forming the bending region 34, in particular be bent.
    Depending on the bending or folding of the sheet metal to be clamped between the clamping jaws 5, 6 to produce the workpiece 2, either the at least one lower clamping jaw 5 or the at least one upper clamping jaw 6 forms the bending region and thus the bending region 34. The at least one lower clamping jaw 5 thus forms or has a first forming edge. The at least one upper clamping jaw 6 forms or has a second forming edge.
    The two previously described clamping surfaces 30, 31 of the clamping jaws 5, 6 define a workpiece support plane 36 for the workpiece 2 to be produced in a mutually abutting position. The workpiece support plane 36 is preferably arranged in the vertical direction at the same height as the support plane 33 defined by the support table 32 , The two planes are preferably aligned plane-parallel to one another and arranged in a common plane.
    The bending unit 35 can have one or even a plurality of bending tools 37, which can be arranged on a tool carrier of a bending beam 38, not specifically described, in particular held thereon. The bending beam 38 can be adjustable relative to the machine frame 7 on bending beam guides (not shown in more detail) by means of a bending beam drive, as is indicated in FIG. 2 by a double arrow. In the present exemplary embodiment, the main adjustment direction of the bending beam 38 runs in the vertical direction and predominantly parallel with respect to the vertically oriented machine plane 28. This corresponds to a shift in the direction of the “Y” direction described above. In addition, at the end of the bending process, the bending tool 37 can be minimally adjusted by means of the bending beam 38 in the direction of the clamping jaws 5, 6, which corresponds to an adjustment in the “X” direction. This allows a slight overbending to be achieved, which means that the correct bending angle can then be maintained after relief due to the springback.

    N2016 / 049-AT-00
    Furthermore, the production system 1 can also include a manipulation device 39 with at least one manipulator 40, which is indicated in a simplified manner, for the usual manipulation of the sheet or the workpiece 2 to be produced in the front or operating area of the bending machine 3. The manipulation of the sheet or the workpiece 2 to be produced therefrom is preferably carried out in the region of the support table by the manipulator 40, of which only a first holding element 41 is shown on part of a manipulator arm. The first holding element 41 can or the first holding elements 41 can e.g. be designed as a suction element and / or as a magnet with which the sheet metal can be held on its side facing away from the support plane of the support table 32 and subsequently moved relative to the clamping tool 4 and aligned in relation to the bending region 34. However, it would also be possible to design the first holding element 41 as a gripper with interacting gripping fingers and, if necessary, to dispense with the support table 32.
    Depending on the bending direction of the sheet to be carried out, either the lower bending tool 37 or the upper bending tool 37 each form a working edge 42 in cooperation with the at least one lower clamping jaw 5 or with the at least one upper clamping jaw 6.
    1 also shows in a simplified manner that in the “Z” direction, a plurality of the upper clamping jaws 6A are arranged next to one another and can additionally be held in the upper clamping jaw receptacle 20 in an adjustable manner in the Z “direction. The adjustment is preferably carried out in the direction of the longitudinal extent of the bending region 34. The relative longitudinal adjustment of at least some of the upper clamping jaws 6A can be carried out or carried out by means of a separate, but not shown, adjustment arrangement and / or also by means of the manipulator 40. It should be mentioned here that the design of an upper tool set 43, which is described in more detail below, from a plurality of upper clamping jaws 6A and at least one second upper clamping jaw 6B can also be applied analogously to a lower tool set 44 with a plurality of lower clamping jaws 5. Either only the upper tool set 43 or only the lower tool set 44 can be designed in this way. But it would also be possible
    N2016 / 049-AT-00 Lich to form both the upper tool set 43 and the lower tool set 44 according to one of the embodiments described in more detail below.
    Each of the individual clamping jaws 5, 6 has a base body, not designated in any more detail. Each of the base bodies can be designed or used to be held and fastened on one of the clamping bars 13, 16, as is well known from the general prior art.
    In this exemplary embodiment, it is also indicated that the at least one second upper jaw 6B in the direction of the longitudinal extension of the clamping bars 13, 16 has at its first end section 46 a first jaw part 47 which can be displaced relative to its base body from a working position to a removal position. Furthermore, the at least one second upper jaw 6B, on its second end portion 48, which is spaced from the first end portion 46 in the direction of the longitudinal extent of the clamping bars 13, 16, may have a second jaw portion 49 which can also be displaced from the working position to the unthreading position.
    The jaw parts 47, 49 of the second upper jaw 6B are each formed with a horn-shaped extension 50. In the working position, each of the lugs 50 projects as a horn on the side or direction facing away from the base body of the second upper clamping jaw 6B, in each case above the base body. If the jaw parts 47, 49 are in the unthreading position, a shortened outer longitudinal dimension of the second upper jaw 6B is formed in the direction of the longitudinal extent of the clamping bars 13, 16. The shortened outer longitudinal dimension in the unthreading position preferably corresponds to a maximum length of the base body of the second upper clamping jaw 6B. A lateral protrusion of the jaw parts 47, 49 beyond the base body can thus be avoided.
    Furthermore, at least one first upper clamping jaw 6A is arranged on both sides of the at least one second upper clamping jaw 6B in the direction of the longitudinal extent of the clamping beams 13, 16. In each case in the direction of the longitudinal road 21/39
    In order to be able to spend the first upper clamping jaws 6A located on the outside in the previously described undercut of the workpiece 2 for the clamping holder, the first upper clamping jaws 6A have at least at their first end regions facing away from the at least one second upper clamping jaw 6B 51 each have a first horn 52. Each of the first horns 52 is projecting over the respective base body of the second upper clamping jaws 6A in the direction of the longitudinal extent of the clamping bars 13, 16.
    In the unthreading position, the entire longitudinal dimension of the upper jaw set 43 is shorter than in the working position. A sufficient clamping effect and the bending edge 45 can thus also be formed in the working position in the region of the at least one undercut formed by workpiece 2.
    The entire bending edge 45 of the upper jaw set 43 is formed in the direction of the longitudinal extent of the clamping beams 13, 16 in the working position by the upper jaws 6A, 6B. An aligned, continuously formed bending edge 45 is preferably selected. Thus, a first partial bending edge 53 is formed from each first upper jaw 6A. Furthermore, a second partial bending edge 54 is formed by the at least one second upper jaw 6B in the working position. The longitudinal dimension of the second partial bending edge 54 is composed of partial lengths of the jaw parts 47, 49 and the partial length of the base body of the at least one second upper jaw 6B.
    3 and 4, the upper jaw set 43 is shown solely based on the representations in FIGS. 1 and 2. This comprises the at least one second upper clamping jaw 6B with the clamping jaw parts 47, 49 which are each arranged laterally on its base body. The clamping jaw parts 47, 49 are shown in FIG. 3 in the working position. On each side and next to it, two pieces of first upper clamping jaws 6A are arranged on each side. Preferably, only a piece of the second upper jaw 6B is used in an upper jaw set 43. The second upper jaw 6B can thus always be arranged in a stationary manner with respect to the upper clamping bar 16.
    / 39
    N2016 / 049-AT-00
    In this arrangement, the at least one second upper jaw 6B is arranged in a central region of the upper jaw set 43. Furthermore, it can also be provided that the at least one second upper jaw 6B of the upper jaw set 43 is arranged at a fixed position with respect to the upper jaw 16. This has the advantage that when the total length of the bending edge 45 required for the bending process is adapted, the second upper jaw 6B can always remain stationary and only the first length and number of the first upper jaws 6A located to the side in each case are to be arranged. Due to the central and fixed arrangement of the second upper jaw 6B, the second upper jaw 6B can also be provided with energy for carrying out the adjustment process of the jaw parts 47, 49 from the working position to the unthreading position and vice versa more easily on the bending machine 3.
    Thus, the number of upper jaws 6A, 6B of the upper jaw set 43 can be selected so that in the working position a total length of the bending edge 45 corresponds to a sum, which sum of the individual lengths of the first partial bending edges 53 of the first upper jaws 6A plus the length of the second partial bending edge 54 of the second upper jaw 6B is formed. The sum formed in this way corresponds at most to a longitudinal dimension of the clamping length to be supported on the workpiece 2 to be produced or the bend to be formed on the workpiece 2 to be produced. The workpiece 2 is indicated in dashed lines in the two FIGS. 3 and 4.
    Due to the central and always positioned arrangement of the second upper clamping jaw 6B, the upper first clamping jaws 6A located laterally next to them can simply be provided in terms of their number and their partial lengths in accordance with the clamping length to be formed and the bending edge 45 and can be assembled as an upper clamping jaw set 43 on the bending machine 3. This can be done by laterally shifting and / or adding and / or removing first upper jaws 6A.
    In both of the outer upper first clamping jaws 6A, it is also indicated in dashed lines that this on their at least one second upper / 39
    N2016 / 049-AT-00
    The second end region 55 facing the jaw 6B may have a second horn 56 projecting in the direction of the longitudinal extension of the clamping bars 13, 16 over the base body of the first upper jaw 6A. The second horn 56 can be used for individual or all first upper jaws 6A.
    Furthermore, the number of upper jaws 6A, 6B of the upper jaw set 43 should be the same in the working position and in the threading position.
    4 shows the shortened threading position of the upper jaw set 43 with the upper jaws 6A, 6B. The two jaw parts 47, 49 arranged laterally of the base body of the second upper jaw 6B are displaced relative to the base body, so that the shortened outer longitudinal dimension of the upper jaw set 43 can be achieved.
    Since a space is now created between the basic bodies of the first upper clamping jaws 6A which are located immediately to the side next to the second upper clamping jaws 6B, all of the first upper clamping jaws 6A arranged next to them can be displaced in the direction of the basic body of the at least one second upper clamping jaw 6B.
    Before carrying out these adjustment movements, the clamping action between the upper and lower clamping jaws 5, 6 is mostly to be released in order not to transmit any damage from one of the clamping jaws 5, 6 to the workpiece 2. With further adjustment, in particular lifting the upper clamping bar 16, the jaw parts 47, 49 are to be adjusted from their working position into the shortened unthreading position. For the sake of clarity, guide arrangements, possible adjustment drives and their energy supply have not been shown. The first upper clamping jaws 6A, which are located on both sides, are also to be displaced in the direction of the second upper clamping jaw 6B into these free spaces which are formed laterally next to the base body of the upper clamping jaw 6B. Thus, in the outermost / 39
    N2016 / 049-AT-00
    Edge regions of the upper jaw set 43 enables collision-free adjustment from the workpiece 2.
    It is also still possible for the lower jaw set 44 to be designed analogously and to be variably assembled, as was described above for the upper jaw set 43. This is shown in simplified form in FIG. 5.
    The clamping tool 4 then also has the lower jaw set 44. The lower jaw set 44 includes a plurality of first lower jaws 5A and at least one second lower jaw 5B. The at least one second lower jaw 5B has on both sides, on its first and second end sections 57, 58 arranged in the direction of the longitudinal extent of the clamping bars 13, 16, a first and second jaw part 47, 49 which can be displaced from the working position into the unthreading position. The jaw parts 47, 49 can be of the same design as the jaw parts described above.
    Here too, at least one first lower jaw 5A is arranged on both sides of the at least one second lower jaw 5B in the direction of the longitudinal extent of the clamping bars 13, 16. The previously described first horn 52 and possibly also the second horn 56 can also be provided.
    The jaw parts 47, 49 can be adjusted in accordance with the methods and techniques known from the prior art. A combined axial adjustment and swiveling movement could thus be carried out. However, a linear inclination adjustment would also be conceivable, as indicated by arrows in FIG. 3.
    Through the joint activation of the jaw parts 47, 49 and the preferred sliding movement of the first jaws 5A, 6A, which all have the rigid horn 52, it is possible to thread out of a box, although the second jaw 5B, 6B with the mobile jaw parts 47, 49 as / 39
    N2016 / 049-AT-00
    Horn tool is in the middle position. The first clamping jaws 5A, 6A are preferably designed as standard tools.
    The jaw parts 47, 49 with the horns or shoulders 50 are in a central position with the respective second jaw 5B, 6B, and can be supplied with energy there directly due to no and / or only a short change in position. This makes it possible to provide the second clamping jaws 5B, 6B with an activation that does not require a tool changer.
    The first jaws 5A, 6A, in particular those of the upper jaw set 43, which participate in the clamping and are therefore arranged within the workpiece 2 designed as a box, are together with the upward movement of the clamping bar 16 and the activation of the second jaw 5B, 6B inwards to push.
    The exemplary embodiments show possible design variants, it being noted at this point that the invention is not limited to the specially illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this variation possibility is based on the teaching of technical action through the present invention Ability of the specialist working in this technical field.
    The scope of protection is determined by the claims. However, the description and drawings are to be used to interpret the claims. Individual features or combinations of features from the different exemplary embodiments shown and described can represent independent inventive solutions. The object on which the independent inventive solutions are based can be found in the description.
    For the sake of order, it should finally be pointed out that, for a better understanding of the structure, elements have sometimes been shown to scale and / or enlarged and / or reduced.
