Local adjusting method of bending machine deflection compensation workbench

Abstract

The invention discloses a local adjusting method of a bending machine deflection compensation workbench, and belongs to the technical field of bending machines. The local adjusting method comprises the following steps that 1, the bending machine deflection compensation workbench is mounted; 2, at a set of transverse adjusting positions needing local adjustment, screws at the corresponding positions are loosened firstly; 3, then fastening bolts are rotated, a lower sliding plate is pushed to move to the designated position in the transverse direction, the transverse relative positions of the upper sliding plate and the lower sliding plate change at this moment, and the upper surface heights of cover plates at the corresponding positions change on the lower surface of the upper sliding plateand the upper surface of the lower sliding plate under the action of one pair of bevels in the transverse direction; and 4, finally, the screws at the corresponding positions are locked, and the local adjusting function of the upper surface heights of the cover plates is completed. According to the method, the deflection compensation quantity of a workpiece is matched with the practical deflection deformation of the workpiece, and the whole-length consistency of the bending angle of the workpiece and the straightness of the workpiece are guaranteed.

Description

[0001] The patent application of the present invention is a divisional application with the application number: 2015102925853. The filing date of the original application is: 2015-05-29. The name of the invention is: a bending machine deflection compensation worktable capable of local adjustment. technical field [0002] The invention relates to the technical field of bending machines, and more specifically, to a local adjustment method of a deflection compensation workbench of a bending machine. Background technique [0003] 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 b...
