    The invention relates to a manufacturing apparatus, in particular a bending press, and a method for forming a workpiece from sheet metal according to the preamble of claims 1 and 9.
    In sheet metal bending equipment, such as bending presses or press brakes, depending on the type and extent of bending operations to be applied to a workpiece, different bending tools must be used in the tool seats of the press table and the press beam. In the meantime, press brakes with automatically operating tool change systems are also known. These have manipulation devices with correspondingly formed grippers for receiving and moving the bending tools between a tool storage and the tool holders in the press table or in the press beam. For the gripper, different principles of action are applicable, for example mechanical grippers or grippers are known using force by electromagnets or by vacuum.
    In certain bending processes or bending work, it is also common to arrange a plurality of bending tools close together lying in the tool holders of the press table and the press beam and fix. For tool change, the fixation of the tool holders is first to be solved again. When changing the bending tools, it is possible - if a single bending tool segment is to be removed - to prevent adjacent segments from sticking to one another. This is the case, for example, if oil residues between the side surfaces of the bending tool segments enter or if they adhere to one another by the formation of residual magnetism. Especially with automatic tool change systems this has
    Malfunctions result. For example, it can happen that the wider, adhering bending tool segment is moved along part of the transport path and finally remains in an unpredictable position. Or the initially adhering bending tool segment detaches, tilts and falls out of the tool holder, where it can even be damaged. As a result, manual intervention is inevitable to restore proper operation. Such malfunctions are therefore particularly disadvantageous in particular in automatic tool changing systems.
    It is the object of the invention to provide a manufacturing device or a method for operating a production device or bending press for forming a tool made of sheet metal, through which the reliability is increased.
    This object of the invention is achieved by a method for operating a bending press for forming a Werkstiicks made of sheet metal, wherein the bending press is formed with a table bar and a table beam opposite the parallel aligned parallel press beam, and wherein on the table bar and on the press bar tool holders for fastening Biegewerkzeu gene are formed, solved. In the method, it is also provided that the bending press comprises a stop device for positioning the workpiece to be machined. When exchanging an arrangement of two or more Biegewerkzeugen before lifting a first, to be moved away bending tool or before inserting a first, to be used bending tool, the stopper to a second bending tool for conditioning and thereby held this second bending tool in the tool holder , In this case, the first bending tool and the second bending tool are arranged in a fixed position in the tool holder position immediately adjacent. This procedure has the advantage that the bending tools to be manipulated during replacement are always kept in a defined position and alignment. This is even though the tool holders own clamping device is disabled during the replacement of the bending tools.
    It is also advantageous that in the method, the stop means comprises an impact body and the stopper body is brought to the second bending tool for conditioning.
    An advantageous development of the method provides that the stop body of the stop means comprises a carrier in a end portion facing the tool holders and a tool clamping device is arranged on a lower side of the carrier and the tool clamping device is brought into contact with the second bending tool. The use of the tool clamping device offers the possibility of an embodiment of their contact surfaces with a higher frictional engagement, for example by designing with an increased surface roughness.
    Another advantage is also a procedure in which a tool storage is ausgebil-det and the wegzubewegende bending tool in the tool storage is abge laid or the bending tool to be inserted into the tool holder is removed from the tool storage. This ensures that the bending tools, even when not in use, are in a secured position and orientation.
    Furthermore, it is provided in the method that a transport device is designed with a gripper and the first bending tool is pulled or pushed for transport from the transport device in the tool holder in a direction parallel to the Längserstre-ckung the tool holder direction. This has the advantage that the groove-like tool holders simultaneously serve as guide tracks for the transport of exchangeable bending tools.
    Also advantageous is the procedure in which a control device is designed and the stop device is moved motor-driven by control commands of the control device.
    According to a development of the method, the transport device is also moved by control commands of the control device. This has the advantage that the tool change of the bending tools can be done automatically.
    In the method, it can also be provided that a second transport device is formed and the arrangement of the two or more bending tools is moved by the second transport device into an adjustment range that can be achieved by the stop device before the first transportable bending tool is removed. This has the advantage that thus the achievable range of action for the bending tools to be replaced is increased.
    The object of the invention is also independent by a bending press for forming a workpiece made of sheet metal with a table bar and the table bar opposite and parallel aligned press beams and formed on the table bar and on the press bar tool holders for attachment of bending tools and with at least one Stop device for positioning the workpiece to be machined solved. It is also provided that the stop device is formed on one of the tool holder end portion facing a Werkzeugklemmeinrich-device. This has the advantage that a higher frictional engagement between the stop device and the fixed bending tools can be achieved by the tool clamping device.
    According to a development of the bending press is provided that the stop means comprises a stop body with a stop edge and a Trä-ger, wherein the tool clamping device is attached to an underside of the Trä-gers.
    According to an advantageous embodiment of the bending press is provided that the tool clamping device projects beyond the tool receiving end portion of the carrier in the horizontal direction. By projecting the tool clamping devices in the direction of the bending device beyond the end of the carrier, the holding of the bending tools with the tool clamping device can also be achieved by pressing in the horizontal direction.
    Another advantage is the development according to which the bending press is designed with a tool storage for storage of bending tools.
    It is further advantageous if a transport device is designed with a gripper for grasping the bending tool, a movement range of the gripper extending between the tool holder and the tool store. According to one development of the bending press, provision is made for a second transport device to be formed, wherein a movement region of the second transport device extends parallel to the longitudinal extent of the tool receptacle.
    The bending press is advantageously designed with a control device, wherein the stop device can be adjusted by control commands of the control device.
    Another advantage is the development of the bending press, according to which the transport device and the gripper are adjustable by control commands of the control device.
    According to a further embodiment of the bending press is provided that the tool clamping device is made of rubber or a rubber-like material. This provides the advantage that a higher frictional engagement can be ensured or that damage to surfaces of the stop device, on the one hand, and of bending tools that are brought together with one another on the other hand can be avoided.
    According to a further alternative embodiment of the bending press is provided that the bending tool is formed with a hole and the tool clamping device with an insertable into the hole bolt. Thereby, the retention of a bending tool in the tool holder can be achieved by positive engagement of the tool clamping device in the bending tool.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description can be transferred mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these situation information in a change in position mutatis mutandis to the new situation to transfer.
    1 shows a manufacturing plant formed by a bending press 1 or a press brake for the production or for the transformation of a workpiece 2. The bending press 1 has for this purpose a table beam 4 fixed to a machine frame 3 and a press beam adjustable relative to the table beam 4 5 on. As bending tools a bending die 6 are attached to the table bar 4 and a punch 7 on the press bar 5. With the aid of a drive arrangement 8 and a linear guide arrangement 9, the press bar 5 with the bending punch 7 attached thereto is guided against the table beam 4 with the bending die 6 and thus acted on the workpiece 2 lying between the bending die 6 and the bending punch 7.
    To control the ablaut of the forming process or the bending press 1 overall, a control device 10 is provided. The control device 10 may in turn be operated by an input terminal 11 by a user of the press brake 1. In addition to the control of the drive assembly 8 for moving the press bar 5 up and down, the control device 10 may also be connected to other components of the bending press 1 for their control. Thus, the bending press 1 according to this embodiment comprises as such a controlled component stop means 12. This comprises a An-impact body 13 with a vertically extending stop edge 14 and a Trä-ger 15. The stop edge 14 and the carrier 15 of the correspondingly positioned stopper body 13 allow a exact alignment of the workpiece 2 when inserting into the bending press 1 or on the bending die 6 before the execution of the forming process. In FIG. 1, this situation can be seen on the undeformed workpiece 2 represented by dashed lines. The adjustment of the stop device 12 is preferably motor-driven and corresponding to a control by the control device 10.
    When changing the workpiece 2 to be produced on the bending press 1, it may be necessary to exchange the bending tools, that is to say the bending die 6 and the bending punch 7, and also to reposition the stop body 13 of the stop device 12. An exchange of the bending tools is made possible by the fact that 5 tool holders 19, 20 are provided on opposite and mutually parallel end faces 17,18 of the table beam 4 and the press bar.
    The tool receivers 19, 20 have substantially groove-shaped receiving slots, which extend in the direction of the longitudinal extent of the table beam 4 and the press bar 5. By means of suitable clamping devices (not shown) with which the tool holders 19, 20 are formed, the bending dies 6 and the punch 7 can each be clamped in the table bar 4 and the press bar 5. It is also provided in particular in the tool holder 20 of the press bar 5, that the clamping device is formed in two stages. In a first stage, the fastening is initially only loosened. This prevents that upon release of the clamping of the tool holder 20 of the punch 7 falls out of the receiving slot. It is thus possible that, when the clamping of the tool holders 19, 20, the bending tools, Biegegesenk 6 and bending punch 7, in the direction of the longitudinal extent of the receiving slots of the tool holder 19, 20 can be moved laterally. This possibility of laterally displacing the bending tools in the receiving slots of the tool receivers 19, 20 simultaneously provides a basis for the design of bending presses 1 with automated tool changing devices.
    The bending press 1 comprises an automated tool changing system, wherein the stop body 13 of the stop device 12 according to the invention is formed with a tool clamping device 21. This tool clamping device 21 is used when bending tools on the tool holders 19, 20 are to be replaced. Namely, it is particularly advantageous if two or more bending tools are arranged side by side in one of the tool holders 19, 20. The stop device 12 can be moved or moved so that finally the tool clamping device 21 selectively abuts one of the bending dies 6 in such a way that this bending die 6 is held in its current position.
    FIGS. 2 to 7 show a sequence of manipulation steps of an automated tool change of a bending press 1 with a tool change system. The illustrations according to FIGS. 2 to 7 show frontal views of the bending press 1 according to FIG. 1. The bending press 1 with the tool change system also comprises a tool store 22 for receiving or storing bending dies 6 or bending dies 7 a transport device 23 is provided, with which individual bending tools can be moved back and forth between the tool store 22 and the tool receivers 19, 20. For this purpose, the transport device 23 is formed with a gripper 24, with which the bending dies 6 and the punch 7 can be detected and moved. According to this embodiment, the transport device 23 is formed by a telescopic arm. This has a parallel with respect to the longitudinal extent of the tool holders 19, 20 directed movement range. A detected by the gripper 24 Biegegesenk 6 can thus be drawn or gescho-ben in the tool holder 19 in the manner of a linear guide. According to this embodiment, the gripper comprises a Elekt-romagneten, by the activation of a bending die 6 can be detected or coupled to the gripper 24. However, the detection by the gripper 24 can alternatively be done in other ways, for example by mechanical clamping. Another alternative is suction cups, which can detect the bending tools with the aid of a vacuum pump.
    2 shows an initial situation of the bending press 1 after completion of a manufacturing process or before the start of a tool change. In order to be able to move the bending dies 6 from their current position in the tool holder 19, the clamping device of the tool holder 19 is first of all deactivated or released.
    By extending the telescopic arm of the transport device 23, the gripper 24 is moved toward a first bending die 6 to be moved (FIG. 3). Meanwhile, the stopper 12 can be repositioned. Namely, the stopper 12 is maneuvered such that finally the tool clamping device 21 comes to rest on a to be moved, the first bending die 6 adjacent second bending die 6 to the plant. For this purpose, the stop device 12 is preferably lifted and moved horizontally so far that the tool clamping device 21 comes to rest on the underside of the carrier 15 of the stop body 13 above the adjacent, second bending die 6. By lowering the stopper 12 with the tool clamping device 21 and finally with the application of a corresponding vertical pressing force 25, the first bending die 6 adjacent second bending die 6 is clamped or held.
    Finally, the gripper 24 couples by activating the electromagnet to the first, wegzubewegende bending die 6 and is pulled by retracting the telescopic arm of the transport device 23 in the direction of the tool memory 22 out where the bending die 6 can be stored. (Fig. 4).
    Subsequently, the stopper 12 is lifted with the Werkzeugklemmein- device 21 again and moved as far as the side that the tool-clamping device 21 comes to rest on the third bending die 6 and now this is held by pressing down with the tool clamping device 21.
    As shown in FIG. 6, the second bending die 6 can now be grasped and moved by the gripper 24 (FIG. 7).
    The tool change described is preferably carried out automatically according to the control commands issued by the control device 10 (FIG. The stop device 12 according to the invention takes over as an additional function the temporary holding of bending tools in the tool holders 19, 20 during the tool change to the bending press 1. By this procedure can be prevented that when moving individual bending tools with the conveyor 23 two Or several of the bending tools unintentionally stick to each other. Experience has shown that such a sticking of bending tools can lead to the fact that at a later time or at an unpredictable position on the path between the tool holders 19, 20 and the tool storage 22 finally comes to a separation or separation of adhering bending tools and automated resulting tool change is disturbed or blocked. In the worst case, it may also happen that bending dies 6 fall out of the tool holder 19 and are damaged. In any case, such interference requires intervention by an operator in order to be able to continue the proper operation of the bending press 1 again.
    According to one embodiment variant of the tool change system of the bending press 1, provision can also be made for the support 15 of the stop body 13 of the stop device 12 to act alone as a tool clamping device.
    Advantageously, comes as a tool clamping device 21 made of rubber, ins-particular made of hard rubber block or made of a similar material having elastic properties elastic material produced component used. As with the frictional engagement between the contact surfaces can be improved. But this can also be avoided that it comes to damage the parts coming into contact with each other or an overload of the mechanics and the drive of the stopper 12.
    The repositioning of an arrangement of bending dies 6 on the tool holder 19 of the table beam 4 will be described with reference to the following FIGS. 8 to 13. Fig. 8 shows the positioning of the first bending die 6 on the tool holder 19. Before the gripper 24 of the transport device 23 is released from the bending die 6 and moved back, the stopper 12 is brought to the bending die 6 to the plant, so that it in the ge desired position is held. Once the pressure force 25 is exerted by the stopper 12 on the bending die 6, the electromagnet of the gripper 24 can be deactivated and then the gripper 24 are removed from the bending die 6. By retaining the bending die 6 with the stop device 12, it is possible to prevent the bending die 6 and the gripper 24 from sticking to each other due to any residual magnetism remaining despite switching off the electromagnet of the gripper 24.
    FIG. 9 shows how a second bending die 6 is moved by means of the transport device 23. The first of the two bending dies 6 now remains held by the stop device 12 until the second bending die 6 has come into contact with the first bending die 6 and has come to a standstill (FIG. 10). Subsequently, the stopper 12 is adjusted so that its tool clamping device 21 finally comes to rest on the second bending die 6 and this is held (Fig. 11). After deactivation of the electromagnet of the gripper 24 of the transport device 26, the telescopic arm of the transport device 26 is moved back again (FIG. 12).
    FIG. 13 shows how a third bending die 6 is brought by means of the transport device 26 to the two first bending dies 6. The holding a Biegegesenk 6 Fleranbewegen another Biegegesenk 6 for joining an array of bending tools ensures that already positioned bending tools can not be repelled or possibly moved to the can.
    The thus automatically performed tool change on the bending press 1 is finally completed by the fact that the arrangements of the bending tools in the respective tool holders 19, 20 by the activation of the clamping means of the tool holders 19, 20 (not shown) are jointly-sam fixed. Such activation of the clamping device of the tool holder 19, 20 is usually carried out simultaneously over the entire Längserstre-ckung of the tool holders 19, 20 and the table beam 4 and the press-senbalkens. 5
    Alternatively to the retention of bending tools with the stopper 12 during the tool change to the bending press 1, a se-selective activation of the tool holders 19, 20 own clamping devices could be provided. For this purpose, the clamping devices could be formed for example by a plurality over the longitudinal extent of the tool holder 19, 20 arranged and laterally retractable or extendable bolt.
    FIGS. 14, 15 show a further embodiment of the bending press 1, which is possibly independent of itself, wherein the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 to 13. To avoid unnecessary repetition, reference is made to the detailed description in the preceding.
    FIGS. 14 and 15 show a further embodiment variant of the tool changing system of the bending press 1. In this case, the bending press 1 comprises, in addition to the transport device 23 with the gripper 24, a second transport device 26. As shown in FIG. 14, the bending dies 6 are located as far outside Nes reachable by the stopper 12 adjustment range 27 that a holding with the tool clamping device 21 is not possible. With the aid of the transport device 26, the arrangement of the juxtaposed bending dies 6 can first be displaced as a whole into the region of the adjustment region 27 of the stop device 12 in the tool holder 19. Subsequently, the tool change, as described above with reference to FIGS. 2 to 7, be made.
    The situation described with reference to FIGS. 14 and 15, in which an arrangement of juxtaposed bending dies 6 or bending punch 7 (not shown) is located outside the adjustment region 27 of the stop device 12, is due to the design of the bending press 1 described in the exemplary embodiment conditionally. The table bar 4 with the tool holder 19 and the press bar 5 with the tool holder 20 are arranged on side walls of the machine frame 3 such that the tool holders 19, 20 or the table bar 4 or the press bar 5 extend laterally beyond the machine frame 3. protrude or laterally survive.
    FIG. 16 shows a detail of the bending press 1 according to FIG. 1 with a stop device 12 according to an alternative embodiment of the tool clamping device 21.
    According to this embodiment, the tool change takes place in an arrangement of juxtaposed bending dies 6 characterized in that the wegzubewegenden, first bending die 6 immediately adjacent, second bending die 6 is held by applying a force acting in the horizontal direction Andmckkraft 28 in its current position in the tool holder 19 , This is achieved by bringing the stop device 12 from the rear (i.e., from the left according to Fig. 16 or Fig. 1) to the bending die 6 until finally the tool clamping device 21 abuts against the bending die 6. The tool clamping device 21 is attached to the underside of the carrier 15 of the stopper 13 on the carrier 15. The tool clamping device 21 is preferably fastened to an end region of the carrier 15 facing the bending die 6 such that the tool clamping device 21 projects beyond the end region of the carrier 15 pointing towards the bending die 6 in the horizontal direction. By projecting the tool clamping device 21 beyond the end region of the carrier 15, it is achieved that, in holding the bending tools, only the tool clamping device 21 comes into contact with them.
    By the procedure described, on the bending tools during tool change a transverse to the longitudinal extent of the tool holders 19, 20 directed Andmckkraft 25 (FIG. 3) or pressing force 28 (FIG. 16) herausiiben, between the bending tools and the tool holders 19, 20 acting stiction increased accordingly, which may be overcome adhesion forces acting on each other between adjacent bending tools. This prevents that during the movement of a bending tool from an arrangement of adjacent bending tools to each other adhering bending tools can be moved with.
    FIG. 17 shows a further embodiment of a bending press 1 with a tool change system. The tool change system according to this exemplary embodiment comprises a transport carriage 29 with a pivotable gripper arm 30. For the transport carriage 29 of the tool change system, a vertical guide 31 and a horizontal guide 32 are also provided by means of which the transport carriage 29 can be moved. By means of the gripping arm 30 of the transport carriage 29, the bending tools 6, 7 between the tool holders 19, 20 and the tool storage 22 can be moved back and forth. In this method for changing tools in the bending press 1 is provided that during the removal of bending die 6 with the gripping arm 30 of the transport carriage 29 a the wegzubewegenden Biegegesenk 6 neigh bending Bgesgesenk 6 by the stopper 12 and by the tool clamping device 21 in the Tool holder 19 is held. In contrast to the exemplary embodiments according to FIGS. 1 to 16, in this tool change system, the bending tools 6, 7 are not pushed into or out of the tool receivers 19, 20, but are removed or inserted directly by the gripper arm 30 , Such removal or insertion is commonly referred to as "pick and place".
    The described procedure with a retention of bending tools during a tool change can thus in both cases, i. both in a displacement of the bending tools in the tool holders 19, 20 and in the immediate removal by means of a gripping arm 30, are applied.
    FIG. 18 shows a detail of the bending press 1 according to FIG. 1 with a stop device 12 of a further alternative embodiment. The bending tool formed by the Biegege-6 6 is held by a positive connection between the tool clamping device 21 of the stopper 12 and the bending die 6. For this purpose, the bending die 6 has a hole 33 running perpendicular to the longitudinal extension of the tool holder 19. On the other hand, the tool clamping device 21 comprises a bolt 34. By adjusting the stop device 12, the bolt 34 of the tool clamping device 21 can be inserted into the hole 33 of the bending tool or the illustrated bending die 6 and thus positively locking in its respective position in the tool holder 19 be held.
    This use of the stopper 12 in the tool change of bending tools on the bending press 1 has the particular advantage that for this only minor structural adaptations is required. In the most favorable variant, the stop device 12 or its carrier 15 is used to hold the respective bending tools in the tool holders 19, 20. This can save both costs and space. All that is required is that the stop device 12 can be adjusted relative to the table beam 4 of the bending press 1 in all three spatial directions. The adjustment of the stop device 12 with the tool clamping device 21 is preferably carried out by means of a motor and in accordance with the control commands of the control device 10, that is to say automatically.
    The embodiments show possible embodiments of the bending press 1, which should be noted at this point that also various combinations of the individual embodiments are possible with each other.
    The task underlying the independent inventive solutions can be taken from the description. All statements of value ranges in the present description should be understood to include any and all sub-ranges thereof, e.g. the indication 1 to 10 should be understood to mean that all subregions, starting from the lower limit 1 and the upper limit 10, are included, i. all portions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.
    For the sake of order, it should finally be pointed out that, for a better understanding of the construction of the bending press 1, these or their components have been shown partly in an uneven fashion and / or enlarged and / or reduced in size.
