- EP 2 362 815 B 1 Another design with two upper cross members is known from EP 2 362 815 B 1, wherein at the top of the cross member a screw-mounted mounting plate is provided, on which the Versteilantriebe 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 by means of at least one fastening means in the form of a clamping means against at least each a downwardly oriented mounting surface is stretched on both cross members.
- the support member is releasably secured by at least one fastener and the Versteilantrieb has an upwardly oriented contact surface, which contacts a downwardly oriented support surface on the support member, it is possible that the support element 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.
- an adjustment drive or even 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.
- the labor-intensive use of special lifting devices, with which the press bar or Versteilantrieb is lifted from below to 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 connecting pieces can largely correspond to the supporting elements, wherein features of the connection with the adjusting drive can be dispensed with.
- 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 fix 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.
- a direct or indirect support on the cross members both upwards and downwards which may result in lower loads for the fastener.
- the recess in the form of a transverse support penetrating receiving slot is formed with horizontally extending mounting surface on at least one upper cross member, the support member through this receiving slot can be inserted 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.
- clamping means comprise screws.
- Custom-made clamping devices can often be dispensed with in this case.

- 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 Versteilantriebes makes it possible to assemble the Versteilantrieb through the two cross members through or to dismantle.
- the pressing beam can be lowered together with the adjusting drive or at least with parts thereof from the top to the mounting position.
- the upper cross member 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 have above the receiving slot continuous webs having a minimum vertical cross-sectional height exceeding 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 a Versteilantrieb.
- Such a segmentation can in particular allow individual support elements with a concave recess in the radial direction, ie laterally to a convex outer periphery of the cylindrical Versteilantriebes and set to cooperate with a collar or a recess of Versteilantriebes forming the contact surface form-fitting manner.
- the adjustment drive comprises at least one hydraulic cylinder and connecting means for the connection of the hydraulic cylinder with the support element simultaneously effect 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.
