Abstract

The invention relates to a bending device for a bending machine, belongs to the technical field of machining mechanical devices, and particularly discloses a bending device for a bending machine for accurately controlling the bending angle and eliminating the drive inertia errors. The bending device comprises a jig table, a torsion disc and a transmission mechanism, and a base shaft, a torsion shaft seat hole, a torsion shaft and an upper half coupling shaft are arranged on the torsion disc; and the transmission mechanism comprises a lower half coupling shaft, a sliding frame, a lead screw, aguide rod and a stepping motor. A hole is formed in the center of the jig table, a large disc bearing is fixedly installed in the hole, the torsion disc is rotationally connected to the upper portionof the jig table through the large disc bearing, the lead screw is rotationally connected to the lower portion of the jig table through a bearing, the guide rod is welded to the lower portion of the jig table, and the upper half coupling shaft penetrates through the hole in the center of the jig table to be movably connected with the lower half coupling shaft.

Description

technical field [0001] The invention relates to the technical field of profile processing mechanical devices, in particular to a bending device for a bending machine. Background technique [0002] Most of the bending mechanisms used in existing bending machines are composed of fixing parts and ejecting parts, and hydraulic motors are used as power to realize profile bending through the parts to be bent of the ejecting parts. It is difficult to accurately control the bending angle in the above-mentioned structural form that achieves bending through the stroke of the ejector, and after the shutdown, due to the deceleration of the motor or the pressure relief of the hydraulic oil, it is a gradual disappearance process, and the inertial driving force still exists during this process, thereby resulting in the bending angle error. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the push-top bendin...
