Embodiment Construction

[0034] exist Figures 1 to 5 A possible embodiment of the press brake 1 according to the invention is shown in , in which certain shown structural features are not to be regarded as mandatory features for the invention, but rather alone or in combination with other structural features In combination, a possible embodiment according to the invention of the press brake 1 can be formed.

[0035] figure 1 A press brake 1 in the form of an edge bender according to the invention is shown in oblique view from the front side on the operator's side. Here, the press brake 1 comprises a machine frame 2 with two sides 3 and 4 spaced apart from each other, which are passed through a fixed lower pressure beam 5 and two fixed upper cross members. 6 and 7 are fixedly connected to each other and thus basically form a fixed part of the machine frame 2 . In the machine frame 2, an upper pressing beam 8 is mounted adjustable and cooperating bending tools, not shown in the figures, can be arran...

Abstract

The invention relates to a bending press (1), in particular a press brake, for shaping a sheet metal workpiece, comprising a machine frame (2) with two mutually distanced lateral walls (3, 4), a stationary lower press beam (5) and an adjustable upper press beam (8) on which interacting bending tools can be arranged, and an adjusting drive (10) which is coupled to the machine frame (2) and to the upper press beam (8), said adjusting drive comprising hydraulic cylinders (27) in particular. The lateral walls (3, 4) are plate-shaped, are formed with O-recesses (22), and are arranged parallel to each other, and the upper press beam (8) is arranged at least partly between two upper cross beams (6, 7) which connects the two lateral walls (3, 4). According to the invention, the lower press beam (5) is connected to the lateral walls (3, 4) below the center of the O-recesses (22), and lateral end portions (23) of the upper press beam (8) are each guided above the center of the O-recesses (22) by means of guide elements (24) arranged on the lateral walls (3, 4).

Description

technical field [0001] The invention relates to a press brake according to the preamble of claim 1 . Background technique [0002] The machine frame of a press brake, in particular of an edge bending machine, usually comprises sides in the form of a C-shaped frame, whereby the user's side is provided not only on the front side but also laterally for Large free space for manipulating workpieces and tools. The disadvantage of this design is that, at high forming forces, the C-stand is bent and the upper pressure beam is thus subjected to a slight inclination from the working plane and thus bending inaccuracies can occur on the workpiece being machined. . [0003] In order to reduce such bending inaccuracies caused by the beveling of the stand, it is known to construct press brakes with so-called O-frames, ie with sides with O-shaped recesses. Such a construction is known, for example, from DE 4138286 A1. The press brake disclosed therein has, in order to increase the bendi...
