    The invention relates to a press brake, as indicated in claim 1.
    From WO2010042962A2 a generic press brake is known.
    The object of the invention is to provide a press brake, which works as accurately as possible and achieves the most uniform possible result of the bend.
    This object of the invention is achieved by a press brake, as indicated in claim 1.
    According to the invention, there is a press brake comprising: a fixed press beam which extends in the press brake longitudinal direction; a first side part, which is seen in the press brake longitudinal direction coupled to a first end portion of the fixed press beam; a second side part which, as seen in the press brake longitudinal direction, is coupled to a second end section, opposite the first end section, of the fixed press beam; a cross member coupled to and extending between the first and second side members; an adjustable pressing beam, which is coupled by means of at least one actuator movable with the cross member provided.
    The cross member is coupled by means of a first joint or a first elastically deformable component articulated to the first side part and coupled by means of a second joint or a second elastically deformable component articulated with the second side part.
    The advantage here is that the cross member is pivotally connected to the side panels. Thus, no bending moments are embedded in the side panels by the cross member. In other words, the side parts are thereby only loaded by a tensile force, whereby they deform less than a load by a bending moment. This can be achieved that the working accuracy of the press brake is increased, since this is only slightly deformed under load, in particular when performing a bending operation. In addition, the longevity of the press brake can be increased, thereby counteracting the reduction of a swelling bending load of any occurring material fatigue.
    Furthermore, it may be expedient that the first and the second joint are each formed by a bolt connection. The advantage here is that a bolt connection is simple and inexpensive to manufacture. In addition, various types of bolt connections are easy to perform, and calculation of such bolt connection is easily possible. Another advantage of a bolted connection is that it allows the side parts to be easily assembled with the cross member, or that it is possible in the event of maintenance to remove the cross member from the base frame of the press brake and thus to provide simplified maintenance of the press brake.
    Furthermore, it can be provided that the two side parts in the region of the bolt connection are each ausgeblldet as a rod and that the cross member is formed in the region of the bolt connection as a fork, which cooperates with a respective rod of a side part. It is advantageous that the cross member may be in its end region in which the bolt connection is executed by the formation of a fork can have an increased bending stiffness. This results from the fact that with a fork the force introduction is divided on two points. The side part, however, which is designed as a rod needs to absorb only a tensile force in the region of the bolt connection, whereby it is possible to form this area as simple and weight-saving.
    In addition, it can be provided that a central pin receiving element is arranged on the two side parts, into which a bolt of the bolt connection is inserted. The advantage here is that such a central pin receiving element by means of mechanical manufacturing is easy to manufacture. In particular, an inner fit for receiving the bolt in a middle bolt receiving element can be made very well, so that a highly accurate and low-backlash bolt connection can be realized. In addition, the middle bolt receiving member can be well positioned on one of the side members and connected to it, for example by means of a welded joint, to provide a high-precision press brake.
    Also advantageous is an expression according to which the middle bolt receiving element is arranged centrally with respect to the thickness of the side part. It can thereby be achieved that when applying a tensile force on the side part by means of the central bolt receiving element, the tensile force is introduced centrally into the side part. As a result, a bending moment is not introduced into the side part by the tensile force.
    Furthermore, it may be expedient that the first and the second joint are formed such that a hinge axis is arranged in the horizontal direction perpendicular to the Abkantpressenlängsrichtung. The advantage here is that seen in the longitudinal direction, a deflection of the cross member of the two joints can be collected so that there is no deformation of the side parts due to the deflection of the cross member.
    According to a development, it is possible that the rod and / or the fork are designed to be divisible in the middle of the hinge axis. This can be achieved that the ease of maintenance or assembly is facilitated.
    In addition, it can be provided that the two side parts are formed as a 0-frame, wherein in each case a recess is provided centrally of a side part. The advantage here is that such a construction of a side part on the one hand is very dimensionally stable and beyond can be carried out very weight-saving.
    Alternatively, it can be provided that the two side parts are formed as C-frame, wherein they have an open in one side C-shaped structure. The advantage here is that a C-frame is open to one side, which can be achieved that the press brake in the region of the punch is not limited by the two side parts, whereby the flexible use of such a trained press brake can be increased.
    Furthermore, it can be provided that the cross member is formed by two carrier elements, which are positioned at a distance from each other, wherein the at least one actuator is arranged between the two carrier elements. It can thus be achieved that the actuators for moving the adjustable pressing beam can be arranged symmetrically on the cross member. As a result, no torsional moment is introduced into the cross member by the actuators. In addition, a fork for the bolt connection can be formed very well by means of the two support elements.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    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 names, wherein the disclosures contained in the entire description can be 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 position information in a change in position mutatis mutandis to transfer to the new location.
    Fig. 1 shows a schematic front view of a press brake 1. Fig. 2 shows a side view of an embodiment of the press brake 1. In the following description, the structure of the press brake 1 based on a combination of Fig. 1 and Fig. 2 will be explained.
    The press brake 1 comprises a machine frame 2 in which a fixed pressing beam 3 and an adjustable pressing beam 4 are arranged. The adjustable pressing beam 4 is mounted in a vertical pressing direction 5 adjustable on the machine frame 2 and thus movable relative to the fixed pressing beam 3. The movement of the adjustable press bar 4 is effected by actuators 6, which connect this to the machine frame 2.
    The fixed pressing beam 3 is preferably coupled directly to the machine frame and thus not adjustable.
    The two pressing bars 3, 4 preferably have a tool holder 7, in which one or more bending tools 8 can be accommodated.
    The bending tools 8 can be formed here as a bending punch or as a bending die. By bending tools 8, a bending edge can be generated in the sheet metal workpiece 9 to be bent. In this case, the bending edge extends in the press brake longitudinal direction 10. The press beams 3, 4 have their greatest longitudinal extent in the press brake longitudinal direction 10. By inserting a plurality of bending tools 8 into the pressing bars 3, 4, which are arranged next to one another in the press brake longitudinal direction 10, the length of the bending edge which can be generated as required can be varied.
    The machine frame 2 comprises a base plate 11, which constitutes the base of the press brake 1. The base plate 11 is used to attach the press brake I to the ground, such as a hall floor.
    Furthermore, the machine frame 2 comprises a first side part 12 and a second side part 13, which are coupled to the base plate 11. The two side parts 12, 13 extending from the base plate 11, starting in the vertical direction upwards. As can be seen from FIG. 1, it is provided that the two side parts 12, 13 are arranged at opposite ends of the base plate 11. In particular, the two side parts 12,13 are arranged in the press brake longitudinal direction 10 seen at opposite ends. For coupling the two side parts 12,13 to the base plate 11, various mechanisms may be provided. For example, it is possible that the two side parts 12,13 are connected by a welded connection to the base plate 11. Furthermore, it is also possible that the two side parts 12,13 are connected by a screw connection to the base plate 11.
    As can further be seen from FIG. 1, it can be provided that the fixed pressing beam 3 is likewise connected to the base plate 11. In particular, it can be provided here that the fixed pressing beam 3 rests on the base plate II. Furthermore, it can be provided that the fixed pressing beam 3 seen in Abkantpressenlängsrichtung 10 is frontally connected at a first end portion 14 with the first side part 12 and at a second end portion 15 with the second side part 13. This can contribute to the fact that the two side parts 12, 13 are additionally stabilized. The machine frame 2 further comprises a cross member 16 to which the actuator 6 is attached or received.
    The cross member 16 is coupled by means of a first joint 17 articulated to the first side part 12 and coupled by means of a second joint 18 hingedly connected to the second side part 13.
    It can be provided that the two joints 17,18 are each designed as a bolt connection 19, wherein in each case a bolt 20 is used to connect the items.
    In particular, it can be provided that the two side parts 12,13 are each formed in the region of the bolt connection 19 as a rod 21 and that the cross member 16 is formed in each case as a fork 22. The bolted connection 19 in the form of rod 21 and fork 22 is characterized in that the fork 22 has a first bolt receiving element 23 and a second bolt receiving element 24, which are arranged on both sides of a central bolt receiving element 25 of the rod 21.
    The individual pin receiving elements 23, 24, 25 may be formed, for example in the form of sleeves, which are constructed rotationally symmetrical and centrally have a through hole for receiving the bolt 20. The sleeves can be produced by a cutting process, such as machining on a lathe. Sockets produced in this way can be welded to one of the two side parts 12, 13 or to the cross member 16 in the production process for producing the press brake 1. Such a welded connection can be realized for example by a laser welding connection.
    In an alternative variant, it is also conceivable that the bolt connection 19 is designed such that the cross member 16 is formed as a rod and that the two side parts 12,13 are formed as a fork.
    As can be seen from Fig. 1 it can be provided that the central bolt receiving element 25 is arranged centrally with respect to the thickness 26 of the side part 12,13. This has the advantage that when applying a tensile force on one of the side parts 12, 13, no bending moment is introduced into the side parts 12, 13, since these are only loaded by a tensile force which acts centrally on the side parts 12, 13.
    Furthermore, it is preferably provided that, as can be seen in FIGS. 1 and 2, an articulation axis 27, which extends centrally of the bolt 20 of the bolt connection 19, is aligned parallel to the press brake longitudinal direction 10.
    As can be seen from FIG. 2, it can be provided that the cross member 16 has a first carrier element 28 and a second carrier element 29, which are positioned at a distance 30 from one another. The two support elements 28, 29 can be held by one or more connecting struts 31 to each other at a distance, so as to form a stable cross member 16 in itself.
    As can be seen in a summary of FIGS. 1 and 2, it can further be provided that the two actuators 6 are arranged between these two support elements 28, 29 and are coupled with these in order to hold the adjustable pressing beam 4 in its position. The connection of the actuators 6 to the cross member 16 may be carried out by means of a screw or welded connection. In a further variant, it is also possible that the actuators 6 are also coupled by an articulated connection with the cross member 16.
    Furthermore, it can be provided that between a side part 12,13 and the adjustable pressing beam 4, a guide assembly 32 is formed, which serves to guide the adjustable press bar 4. It can thereby be achieved that the adjustable pressing beam 4 has increased stability and the actuators 6 thus serve only as pressure or tension elements and do not have to take over the guidance of the adjustable pressing beam 4.
    As can be seen in the embodiment in Fig. 2, it can be provided that the two side parts 12, 13 are formed as a Q-frame. A design as Q-frame is characterized in that the side parts 12,13 have a recess 33. The recess 33 can serve to provide sufficient space for receiving a sheet metal workpiece 9 can.
    FIG. 3 shows another embodiment of the press brake 1, which may be independent of itself, and where the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 and 2. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figures 1 and 2 or reference.
    In the embodiment shown in Fig. 3, the two side parts 12,13 are designed as C-shaped frame. This has the advantage that over-wide sheet metal workpieces 9 can be inserted from a machine front side 34 into the press brake 1 and accommodated therein. The connection of such a C-shaped side part 12,13 to the cross member 16 can also be implemented as in the embodiment shown in FIG.
    FIG. 4 shows a further embodiment of the press brake 1, which is possibly independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 3. To avoid unnecessary repetition, reference is made to the detailed description in the preceding figures 1 to 3 or reference.
    Fig. 4 shows the side view of an embodiment of the side part 12, 13, wherein the bolt receiving member 23, 24 is executed divided in this embodiment. In other words, a bearing cap 35 is formed, which is connected by means of fastening means 36 on the side part 12, 13. The bearing cap 35 and the side part 12,13 are each partially formed as a Flalbschale, wherein in the assembled state of bearing cap 35 and side part 12,13, a cylindrical recess for receiving the bolt 20 is formed.
    Fig. 5 shows a highly schematically simplified representation of a front view of a conventional press brake 1 in which the two side parts 12, 13 are fixedly connected to the cross member 16. As can be seen from Fig. 5, results from the action of pressing forces 37, which by the actuators 6 on the
    Cross member 16 is a deformation of the cross member 16. If the cross member 16, as shown in Fig. 5, rigidly connected to the two side walls 12, 13, a bending moment in the side parts 12, 13 is introduced via this connection. This bending moment causes the side parts 12,13 deform according to the introduced bending moment. This can lead to an increased inaccuracy of the press brake 1.
    In Fig. 6 as well as in Fig. 5, the press brake is shown greatly simplified schematically, in which case the two side parts 12, 13 are coupled by means of a first joint 17 and a second joint 18 with the cross member 16. As can be seen from FIG. 6, no bending moment is introduced into the side parts 12, 13 by the deformation of the cross member 16 due to the pressing force 37, as a result of which they are not deformed during the bending operation. Overall, this results in that an achievable accuracy of the bending press can be increased.
    FIG. 7 shows a further embodiment of the connection of the cross member 16 to the side parts 12, 13, which is possibly independent of itself, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 6. To avoid unnecessary repetition, reference is made to the detailed description in the preceding figures 1 to 6 or reference.
    7 shows a cross section through the cross member 16, wherein it can be seen in this figure that provision can be made for a first elastically deformable component 38 instead of the first joint 17 and a second elastically deformable component 39 instead of the second joint 18 can, by which the cross member 16 is pivotally coupled to the side parts 12,13.
    For the sake of brevity, only the second elastically deformable component 39 is shown in FIG. 7 and described below, wherein it should be mentioned that the first elastically deformable component 38 is only a version of the second elastically deformable component 39 mirrored about the press brake center.
    In order to achieve the articulated connection by means of the second elastically deformable component 39, similar to a second joint 18, it can be provided that the second elastically deformable component 39 has a taper 40, in which it is elastically deformable. As a result, a "quasi-joint" can be provided by the second elastically deformable component 39, which is designed to allow a small angular rotation between the second side part 13 and the cross member 16. In order to achieve the desired properties, it is necessary that the second elastically deformable component 39 has an elastic behavior, as a result of which brittle materials are not suitable for use in the elastically deformable component 39.
    The second elastically deformable component 39 may be formed, for example, as part of the cross member 16 or as part of the second side part 13, wherein only one connection point between the cross member 16 or the second side part 13 is necessary. Alternatively, it can be provided that the second elastically deformable component 39 is formed as an independent component and is connected to both the second side part 13 and to the cross member 16. The connection of the second elastically deformable component 39 to the second side part 13 or to the cross member 16 can be realized by means of a fastening means 41, such as a screw. As an alternative to a fastening means 41, provision may also be made for the second elastically deformable component 39 to be connected to the second side part 13 or to the cross member 16 by means of a cohesive connection, such as a welded connection.
    Further details required for the operation of such a bending press 3, such as, for example, safety devices, stop arrangements and / or control devices, are omitted from the description in order to avoid an unnecessary length of the description.
    As a coordinate system or coordinate direction, the following alignment is selected in press brakes 1 in the present description. The X-coordinate represents the insertion direction of the sheet to be formed and is aligned at right angles with respect to the pressing direction 5. The Y coordinate represents the pressing direction 5 and is vertically aligned. Finally, the Z coordinate is both perpendicular to the X coordinate and the Y coordinate.

    Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.
    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. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all sub-areas 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.
