Problems solved by technology

[0003] A disadvantage of the embodiments known from EP 0 542 610 B1 and DE 41 26 906 A1 is that the support device is designed to be very large, so that the standing space available to the machine operator is very limited
Furthermore, due to the shown construction, a high inertia of the individual elements results, so that the highly dynamic operating modes required in current bending presses cannot be achieved or can only be realized to a limited extent

Abstract

The invention relates to a support device (15) for a press brake, comprising a base frame (24) and a support plate (17) with a bearing surface (18) which can be positioned between a base position (26) and a maximum position (27). The support plate (17) is arranged on a lever linkage system (25) which is connected to a drive unit (32) and which is designed as a parallel kinematics system. The drive unit (32) comprises a crank (35), which is connected to a positioning drive (33) designed as a rotary drive (34), and a rocker (54), which is connected to the crank in an articulated manner. The rocker (54) is connected to the crank (35) by means of an eight rotary joint (55) and to the lever linkage system (25) by means of a ninth rotary joint (56).

Description

technical field [0001] The invention relates to a support device for a flanging press. Background technique [0002] Supporting devices are known from EP 0 542 610 B1 and DE 41 26 906 A1, which are provided for supporting a sheet-metal workpiece to be bent in a bending press during the bending process. The support device can here be mounted on the front side of the flanging press. A support is formed on the support device, on which the sheet-metal workpiece to be bent, in particular the section of the sheet-metal workpiece protruding from the bending press, can be placed. When the sheet metal workpiece moves upwards during the bending process, the support moves accordingly and thus supports the protruding section of the sheet metal workpiece during the entire bending process. Here, the parallel kinematics is designed such that the pivot axis of the support substantially coincides with the bending shaft line of the sheet metal workpiece, so that the surface of the support p...
