Problems solved by technology

The die squeezes the swinging die and the swinging block through the punch to make the swinging die and the swinging block squeeze the two ends of the workpiece, so that the two ends of the workpiece are bent into a certain angle, but in the actual processing process, due to the material of the workpiece Different, resulting in different compensation angles at the bends that need to be aligned, and the above-mentioned molds cannot change the compensation angles, and can only be adapted to bending workpieces of different materials by changing the swing die and pendulum blocks, resulting in a small range of applications
[0004] Secondly, even workpieces made of the same material will have certain differences in compensation angle during use, so the same bending angle will cause overcompensation at the bend of some workpieces, and overcompensated workpieces will also be stuck in the convex On the mold, it affects the continuous work of the mold, and there is no method for processing the overcompensated workpiece in the above patent

Abstract

The invention relates to the field of molds, in particular to a work method of bending molds with a springback compensation function. The bending mold comprises a hydraulic device and a lower mold seat. The hydraulic device is mounted beside the lower mold seat, and an upper mold is arranged on the hydraulic device. A mold groove is formed in the upper mold, the upper mold is located over the lower mold seat, and deviation rectifying mechanisms are arranged at the two ends of the upper mold. A springback mechanism is arranged on the lower mold seat, and a lower mold is arranged at the upper end of the springback mechanism. The bending molds are arranged at the two ends of the lower mold, and the upper end faces of the two bending molds are in arc shapes. Compensation mechanisms are arranged beside the two bending molds. The work method has the beneficial effects that the bent portion of a workpiece can be prevented from excessive compensation, meanwhile, the compensation bending anglecan be adjusted according to the material of a workpiece, and the application range is wider.

Description

technical field [0001] The invention relates to the field of molds, in particular to a working method of a bending mold with a springback compensation function. Background technique [0002] In the process of workpiece processing, it is often necessary to bend the workpiece to form other shapes, but the workpiece will have a certain rebound effect due to its own elastic force after bending, resulting in many workpieces being bent after rebound The angle is not up to standard, resulting in unqualified workpiece. [0003] Chinese Patent No. CN105396914B discloses a bending springback compensation mold, the upper mold includes an upper mold base and a punch, the punch has a bottom angle that matches the bending angle of the workpiece, and has a bending compensation angle; The mold includes a rotatable die, which is installed on the lower die holder and has a bending groove matching the bottom angle of the punch, and the lower die holder is provided with a first reset mechanism...
