A locally adjustable bending machine deflection compensation workbench

Abstract

The invention discloses a partially-adjustable flexibility compensation bench for bending machines and belongs to the technical field of bending machines. The partially-adjustable flexibility compensation bench comprises a cover plate, a base, a sliding plate mechanism and an adjusting mechanism; the base is longitudinally provided with a groove in which the sliding plate mechanism is disposed; the sliding plate mechanism comprises an upper sliding plate and a lower sliding plate; the upper sliding plate is disposed above the lower sliding plate; the lower surface of the upper sliding plate and the upper surface of the lower sliding plate are both longitudinally provided with a plurality of pairs of slants equal in upper and lower slope; the slope of the slants gradually decreases from the longitudinal middle to the two ends; the upper sliding plate and the lower sliding plate are transversely provided with a pair of slants equal in slope. The partially-adjustable flexibility compensation bench has the advantages that flexibility compensation for workpieces is made matching with actual flexibility and deformation of the workpiece, full-length uniformity of bending angle of the workpiece is guaranteed, and linearity of the workpiece is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bending machines, and more specifically relates to a locally adjustable deflection compensation workbench of a bending machine. Background technique [0002] In the bending process of the bending machine, there are often two defects that are inevitable: (1) the force of the structure itself causes small elastic deformation of the slider and the worktable; (2) the wear of the forming die. The former causes deflection and deformation of the workpiece to be processed, and cannot guarantee the consistency of the bending angle of the workpiece over the entire length (that is, there is a bending error between the bending angle at the middle position of the processed workpiece and the bending angle at both ends), while the latter affects the bending angle of the workpiece Straightness of workpiece. In response to the above phenomenon, the traditional method is to manually adjust the compensation block or add ga...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems of poor consistency of the bending angle of the workpiece and poor straightness of the workpiece due to the deflection deformation of the workpiece during the bending process of the existing bending machine, and to provide a bending machine that can be locally adjusted. The machine deflection compensation workbench matches the deflection compensation amount of the workpiece with the actual deflection deformation of the workpiece, ensuring the consistency of the bending angle of the workpiece and the straightness of the workpiece
