    The invention relates to a bending press according to the preamble of claim 1.
    An important requirement of bending presses, in particular press brakes is to achieve the most accurate bending angle of the workpieces to be formed. The machine frame of a bending press plays a major role in this and, for bending presses, a number of different machine frame concepts have been developed which by their nature have not only advantages, but also disadvantages. In order to avoid that an inclined upper pressing beam at high forming forces skew relative to the fixed lower pressing beam occurs, it is known to provide the guides for the upper beam and the attachment of the press drive to specially reinforced frame parts. For this purpose, additional stiffening plates welded into cross members or additional cross members can be used.
    Such a design is known for example from DE 41 38 286 A1, although the rigidity of the machine frame and thus the forming accuracy of a bending press can be increased by the use of two upper cross members, the ease of installation and ease of maintenance, however, can be affected sensitive ,
    Another design with two upper cross members is known from EP 2 362 815 B1, wherein at the top of the cross member a screw-mounted mounting plate is provided on which the adjusting drives of the bending press are attached. This mounting plate is provided to achieve a resilient mounting of the drive means with openings.
    The object of the invention is to provide a bending press, which also meets the criterion of simplified installation and maintenance in addition to high accuracy requirements.
    The object of the invention is achieved in that an upper side of the support element is tensioned by means of at least one fastening means in the form of a clamping means against at least one downwardly oriented mounting surface on both cross members. As a result, the support element is supported during a pressing operation on the cross members and the fastening means need not be designed for the transmission of high forming forces.
    Since the support member is releasably secured by means of at least one fastener and the adjustment has an upwardly oriented contact surface, which contacts a downwardly oriented support surface on the support member, it is possible that the support member is not connected to the machine frame for purposes of assembly or maintenance and the thus existing at this point bridging between the upper cross beams compared to a bending press with a fixed support element changed and in particular simplified workflows during installation and maintenance allows. Thus, for example, an adjusting drive or the complete upper pressing beam can be lowered from above into its mounting position, which is easy to accomplish by means of a hall crane. Furthermore, it is possible to lower the adjustment drive below the mounting position, then attach the support element to the adjustment drive and then lift the adjustment drive together with the support element into the installation position. The labor-intensive use of special lifting devices, with which the pressing beam or the adjusting drive is lifted from below into its mounting position, can be reduced thereby.
    A further increased flexibility in the sequence of assembly and a simplification of maintenance operations can be achieved if the distance between the cross members over the entire length between the side members is bridged only by releasably secured support members and releasably secured connectors. The connectors can largely correspond in their embodiment, the support elements, features that serve the connection with the Verstellan drive can be omitted. The described embodiments of support elements and their attachment to the cross members may also be present mutatis mutandis in the releasably secured connectors.
    An advantageous possibility to define the position of the support elements relative to the cross members may consist in that the attachment surfaces are arranged in recesses in the upper cross members. As a result, a direct or indirect support on the cross members both upwards and downwards, which may result in lower loads for the fastener.
    In one embodiment, in which the recess in the form of a cross member penetrating receiving slot is formed with horizontally extending mounting surface on at least one upper cross member, the support member can be inserted through this receiving slot and inserted into the recess on the other cross member. This facilitates the mounting of the support member and is possible with two aligned receiving slots, the insertion of both sides of the cross member.
    The assembly and maintenance of the adjustment can be facilitated by the receiving slot is widened in a central portion of the mounting surface by an above subsequent manipulation.
    An assembly-friendly and reliable construction of the bending press is achieved when the clamping means comprise screws. Custom-made clamping devices can often be dispensed with in this case.
    A stable support of the support members on the cross beams can be achieved when the clamping means comprise a wedge assembly. The wedge arrangement causes an absolutely backlash-free attachment of the support element and is also suitable for the transmission of extremely high forces.
    The support element is easy to produce if it has a cuboid base body, although variants with a cylindrical base body are possible.
    An embodiment of the bending press in which a clear distance between the upper cross members is greater than a measured in the direction of the distance outer dimension of the adjustment makes it possible to mount the adjusting drive through the two cross member through or to dismantle. In this case, the pressing beam can be lowered together with the adjusting drive or at least with parts thereof from the top to the mounting position.
    In order to avoid a significant mechanical weakening of the upper cross member by the attachment of the receiving slots, it is advantageous if the upper cross member above the receiving slot continuous webs having a minimum vertical cross-sectional height, which exceeds a thickness of the support member.
    Another way to facilitate the assembly process or maintenance may consist of two or more adjacent support elements to form a support element combination, which together form the support surface for an adjustment. Such a segmentation may in particular allow individual support elements with a concave recess in the radial direction, ie laterally to a convex outer periphery of the cylindrical adjustment drive and cooperate with a collar or a recess of the adjustment, which forms the contact surface form-fitting manner.
    Bending press according to one of claims to, characterized in that the adjusting drive comprises at least one hydraulic cylinder and connecting means for the connection of the hydraulic cylinder with the support element simultaneously cause a press connection between a cylinder body of the hydraulic cylinder and a cylinder head of the hydraulic cylinder, wherein the support member a seat for the cylinder head is formed and the connecting means used in the support element clamp the cylinder body against the cylinder head.
    A simple construction in which deformations occurring during operation can be calculated very accurately in advance is achieved when the side stands are plate-shaped and substantially planar.
    A design of the bending press remain relatively low in the torsion of the side stand even at high forming forces results when the upper cross member are arranged on both sides, in particular symmetrical to a running from the lower press beam to the upper press beam vertical working plane.
    By carrying out the side stand as an O-stand, which laterally the working plane between lower beam and upper beam have recesses for performing bending tools, the skew of the upper beam can be kept very low even at high forming forces compared with C-stands.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    1, 2 and 3, a bending press 1, in particular press brake, for forming a sheet metal workpiece 2 is shown.
    The embodiments of FIGS. 1, 2 and 3 illustrate the generic, but not inventive features of a bending press 1 according to the prior art.
    The bending press 1 comprises a machine frame 3 with two mutually distanced side posts 4 and 5, which protrude from a footprint 6, on which the bending press 1 is positioned in the vertical direction. In the illustrated example, the side stands 4, 5 are formed of plate-shaped and substantially planar elements, which are preferably made of steel, like the entire machine frame 3.
    The machine frame 3 further comprises a fixed lower pressing beam 7 connected to the side uprights 4, 5 and an adjustable upper pressing beam 8, which is adjustable relative to the fixed lower pressing beam 7 in a vertical working direction 9 represented by a double arrow.
    The upper beam 8 is mounted by means of guides 10 on the machine frame 3, wherein the guides 10, for example, as shown in Fig. 1, to the
    Side stands 4, 5 can be arranged, but it is also an otherwise arrangement of the guides 10 on the machine frame 3 possible.
    The machine frame 3 further comprises at least two cross members 11, 12, which connect the two side stands 4, 5 in the region of the upper ends, similar to the lower ends of the side stand 4, 5 are connected to each other via the lower pressing beam 7. The cross members 11,12 extend distanced from each other approximately in the horizontal direction and parallel to each other. Preferably, they are, as can be seen in Fig. 2, approximately symmetrical with respect to a working plane 13 which extends from the lower pressing beam 7 to the adjustable, upper pressing beam 8, and in which substantially the adjusting movement of the upper upper beam 8 is carried out.
    The individual components of the machine frame 3 are preferably connected to one another by welded joints, but individual or all connections can also be made by means of detachable connections, for example screw connections.
    To transfer the forming forces on the sheet metal workpiece 2, as shown in Fig. 1, the lower beam 7 and the upper beam 8 is provided with suitable, cooperating bending tools 14, wherein the lower beam press 7 usually a Biegegesenk 15 and the upper beam 8 most Bending punch 16 are attached. At the pressing beam 7, 8 suitable tool holders can be provided to which will not be discussed in detail at this point.
    The adjustment of the guided on the machine frame 3 upper press bar 8 and the application of the forces required for forming operations by means of an adjustment 17, which is coupled to the machine frame 3 and the upper press beam 8. The adjusting drive 17 preferably comprises, as shown in Fig. 1, fluid cylinder or hydraulic cylinder 18 or alternatively spindle drives with electric motors.
    Furthermore, the bending press 1 has measuring systems for detecting machine conditions, in particular a displacement measuring system for the adjustable upper beam 8, optionally force measuring devices for determining forming forces and / or devices for measuring machine deformations, safety devices for monitoring hazardous areas or similar equipped with sensors components and a controlling functions of the bending press 1 control device.
    In this case, the coupling of the adjusting drive 17 with the machine frame 3 via a support member 19, which bridges a distance 20 between the two upper cross members 11,12 and is releasably secured thereto. An essential feature of the coupling between the adjusting drive 17 and the machine frame 3 is that the adjusting drive 17 has an upwardly oriented contact surface 21, which contacts a downwardly oriented support surface 22 on the support element 19. During a forming process, very large forces are transmitted upward by the adjusting drive 17 via its contact surface 21 to the support surface 22 of the support element 19 and thus to the machine frame 3.
    In a generic bending press 1 according to FIGS. 1 to 3, the adjusting drive 17 comprises two hydraulic cylinders 18 which are assigned to the end sections 23 of the upper press beam 8 and these hydraulic cylinders 18 are each detachably connected to the upper cross beams 11, 12 by means of a support element 19. The attachment of the support members 19 with the cross members 11,12 by means of releasable fastening means 24, for example in the form of screws 25th
    In the example shown, a connection between the adjusting drive 17, here in the form of hydraulic cylinders 18 to the support member 19 made by connecting means 26, which are preferably also formed by screws 27. The contact surface 21 of the adjusting drive 17 is pressed by these connecting means 26 against the support surface 22 of the support member 19.
    The detachable connection between the support member 19 and the upper, spaced-apart cross members 11,12 makes it possible to lower the upper beam 8 between the cross members 11,12 ab during assembly of the press brake 1 and then to assemble in its position of use, resulting in a machine frame. 3 would not be possible with non-releasable support elements 19. This lowering of the upper press bar 8 can be done in the simplest case by means of a hall crane and can be dispensed with the use of additional lifting devices.
    If, as shown in Fig. 3, a clear distance 28 between the upper cross members 11,12 is greater than an outer dimension 29 of the adjusting drive 17, and the adjusting drive 17 can be mounted by lowering from above between the cross member 11,12 lowered and mounted together with the upper press beam 8.
    As is further apparent from FIGS. 1 and 2, the side stands 4, 5 connect the lower pressing beams 7 and the upper transverse beams 11, 12 both in front of and behind the working plane 13 which extends from the lower pressing beam 7 to the upper pressing beam 8. Preferably, the power drive point of the adjustment drive 17 is in the working plane 13. Further, both the side stand 4, 5 and the upper cross member 11,12 and the lower pressing beam 7 are arranged symmetrically to the working plane, in the side stand 4, 5 in this embodiment no Bending moments initiated, and thereby conditional deformations as in the use of C-stands are avoided.
    In the illustrated embodiment of the side stand 4, 5, it is also advantageous if they have laterally of the working plane between the lower pressing beam 7 and upper pressing beam 8 recesses 30 for the implementation of bending tools 14.
    In the illustrated embodiments, the abutment surface 21 and the support surface 22 are formed as flat surfaces, but it may also be provided as contact surfaces between the individual components curved surfaces. The surfaces may be curved in one direction or two directions and depending on a centering effect between the two contacting components.
    4 and 5 show in a sectional view and a detail of an embodiment of the invention of a bending press 1, in which a top 31 of the support member 19 by means of a fastening means 24 in the form of a clamping means 32 against a downwardly oriented mounting surface 33 on the two cross beams 11, 12 is tense. As a result, the support element 19 lies, as it were, from below on the cross members 11, 12, whereas in the embodiment described in FIGS. 1 to 3, it bears against the cross members 11, 12 from above. The advantage of the embodiment shown in FIGS. 4 to 12 is that during a pressing operation, the high forces generated by the adjusting drive 17 do not have to be transmitted via the fastening means 24, but the support element 19 in this case in a pressing operation from below against the Mounting surface 33 is pressed on the cross members 11,12. As a result, the clamping means do not have to be dimensioned for the high forming forces of the bending press 1, but essentially only for the downwardly directed weight forces of the adjustable pressing bar 8, as well as the adjusting drive 17 and possibly bending tools attached to the pressing bar 8. The attachment surfaces 33 may be formed in the simplest case of the underside of the cross member 11,12 or, as shown in Figs. 4 and 5, be arranged in recesses 34 in the cross members 11,12.
    In the embodiments shown, such a recess 34 for receiving the support member is preferably formed in the form of a cross member 11,12 penetrating receiving slot 35, whereby the support member can be inserted through this receiving slot 35 and inserted into a matching recess 34 on the other cross member 12, 11 , which may also be formed as a receiving slot 35.
    In Fig. 5, a situation in the assembly of such a bending press 1 is shown. In this case, the adjusting drive 17 is lowered together with the upper pressing bar 8, not shown, between the cross members 11,12 by a lowering movement 36 shown as arrow below the final mounting position and the support member 19 inserted through a receiving slot 35 in the cross member 11 from the side and into the recess 34 on the second
    Cross member 12, are used here in the form of another receiving slot 35.
    6 then shows how the adjusting drive 17 is connected together with the pressing bar 8 in an upward movement 37 with the underside of the supporting element 19, whereby the contact surface 21 on the adjusting drive 17 contacts the supporting surface 22 on the supporting element 19.
    In Fig. 6 while the support member 19 is connected at the end shown on the left with a fastening means 24 in the form of a screw 25 to the cross member 11, said fastener 24 is also the clamping means 32, with the top 31 of the support member 19 against the mounting surface 33rd of the cross member 11 is stretched in the receiving slot 35. As an example of an alternative or additional form of attachment, the support element 19 is connected at its right end by means of a fastening element 24 or clamping element 32 in the form of a wedge arrangement 37 to the right cross member 12 in FIG. The wedge assembly 37 may, as shown in Fig. 6, consist of two wedge elements or also of a wedge, which cooperates with an inclined surface with the underside of the support member 19. The use of a wedge assembly 37 on the underside of the support member 19 on the one hand ensures a bracing of the top 31 against the mounting surface 33 on the cross members 11,12 and also ensures large-scale transmission of the weight forces of the press bar 8 and the actuator 17 to the machine frame. 3
    Of course, in a bending press 1 according to the invention, the support elements 19 can be connected to the cross beams 11, 12 consistently by the same method, but combinations of the described fastening possibilities are also conceivable.
    A further embodiment of a bending press 1 is shown in FIGS. 7 and 8, wherein the embodiment features shown therein can also be combined with design features of other embodiments.
    In this variant, in turn, the support member 19 which, as in the other embodiments, a cuboid base body, mounted in receiving slots 35 in the cross members 11,12 and is the top 31 of the support member by means of clamping means 32 against the downwardly directed mounting surfaces 33 in the cross beams 11, 12 stretched. In contrast to the embodiment of FIGS. 4 to 6, the clamping means 32 are not arranged in the form of screws 25 in the cross members 11,12, but here separate clamping pieces 38 are provided which bridge the distance 20 between the cross members 11,12 and For example, as shown in Fig. 7 and 8, rest on the upper side. By this embodiment can be dispensed with the production of additional holes in the cross members 11,12, whereby the manufacture of the machine frame 3 is facilitated overall.
    Since on the support element during forming processes sometimes very large forces must be introduced into the machine frame, it is advantageous if cross beams 11,12 with receiving slots 35 above the receiving slots continuous webs 39 are made, which have a minimum vertical cross-sectional height 40, which is the thickness 41 of the support member 19 exceeds and thereby have a high strength and rigidity.
    FIGS. 9 and 10 show a further embodiment of a 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 8. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 9 or reference.
    In the embodiment according to FIGS. 9 and 10, an adjusting drive 17, in this case in the form of a hydraulic cylinder 18, is coupled to the cross members 11, 12 in each case by means of two support elements 19. The support members 19 may, as shown, be arranged on the underside of the cross member 11,12, but it is also the use of such support members 19 in receiving slots 35 or other attachment positions possible.
    Preferably, these support elements 19 may have a rectangular basic shape and semicircular recesses 42, and be combined to form a support element combination 43, wherein the adjusting drive 17 protrudes through the recesses 42. The contact surface 21 on the adjusting drive 17 is formed in this embodiment by a collar 44 on the cylinder housing. As shown in Fig. 10, it is possible that the support elements 19 in the marked horizontal directions 45, which extend parallel to the working plane 13, are pushed to the adjustment drive 17.
    In Fig. 11, a further embodiment of a bending press 1 is shown, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are mutually possible and this variation possibility due to the teaching to technical action by objective invention in the skill of those working in this technical field expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.
    In this embodiment, the support member 19 is tensioned by two wedge assemblies 37 with its top 31 against the mounting surface 33 and serve the wedge assemblies 37 in this case as a clamping means 32. The mounting surface 33 is in turn formed in a recess 34 in the form of a receiving slot 35 and supports the adjusting drive 17, as already described with reference to FIG. 10, with a collar 44 on the underside of the support member 19 from. On the presentation of additional fasteners between the support member 19 and cross members 11,12 and on the representation of the connecting means 26 between adjusting 17 and support member 19 is omitted at this point. As shown in FIG. 11, the wedge arrangement 37 acts in such a way that a lateral pushing together of wedge elements causes the pressing of the support element 19 against the upper side of the receiving slot 35. This lateral pushing can be effected for example by screws, not shown, or the like.
    Furthermore, a support element combination 43 can be formed from two support elements 19, as has already been described with reference to FIG. 10, and the support elements 19 can be pushed horizontally from the side to the adjustment drive 17. In this case, the adjustment drive 17 does not have to be lowered below the receiving slot 35 during assembly.
    Fig. 12 shows an oblique view of a section through the connection of an actuator 17 in the form of a hydraulic cylinder 18 with the upper cross members 11,12.
    The attachment of the support member 19 is similar to the embodiment of FIG. 7, in which the clamping means 32 are not performed in the form of screws 25 through holes in the cross members 11,12, but clamping pieces 38 are used at the top of the cross member 11,12 and the tensioning means screws 25 extend between the cross members 11,12.
    The receiving slots 35 are, as in the previously described embodiments provided at their ends with the largest possible rounding radii, in order not to weaken the mechanical strength of the cross member 11,12 by strong notch effect. Furthermore, the receiving slots in an intermediate portion of the mounting surface 33 on an extension by an above subsequent manipulation recess 46. This manipulation recess 46 facilitates the manufacture and accessibility of the hydraulic connections on the hydraulic cylinder 18.
    Fig. 12 also shows a possible embodiment for the connection of the hydraulic cylinder 18 with the support member 19. The support member has a recess for the cylinder head 47 of the hydraulic cylinder 18 and the cylinder body 48 of the hydraulic cylinder 18 with the connecting means 26 in the form of screws 27 against pressed the cylinder head 47.
    The embodiments show possible embodiments of the bending press 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are possible with each other and this possibility of variation due to the teaching of technical action representational invention in the skill of those skilled in this technical field.
