Torsion beam lower die with opposite air cylinders

Abstract

The invention discloses a torsion beam lower die with opposite air cylinders. Cavities are symmetrically arranged at the left end and the right end of a die holder, and a wedge block is arranged in each cavity of the die holder; upright posts are arranged at four corners of the top surface of the die holder, the upright posts are cylinders, the four upright posts are in rectangular distribution, the lower ends of the upright posts are fixed to cushion blocks, and the cushion blocks are fixedly connected with the die holder via bolts; a front row of stop blocks and a rear row of stop blocks are arranged in the middle of the top surface of the die holder, each stop block is a two-segment hollow short column with a small top and a large bottom, and screws penetrate the centers of the stop blocks and fixed to the die holder; guide grooves are symmetrically formed in the front edge and the rear edge at the left end of the die holder, guide grooves are also formed in the front edge and the rear edge at the right end of the die holder, and the four guide grooves are in rectangular distribution; and abrasion-resistant plates are mounted on three inner walls of each guide groove, and the abrasion-resistant plates are steel plates. The lower die has the advantages as follows: the design is reasonable, a formed torsion beam is simple and convenient to operate, the labor intensity of workers is low, the production efficiency is high, and the left and right directions of the formed torsion beam are easy to identify.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a counter-cylinder type torsion beam lower die. Background technique [0002] The torsion beam is an important part of the car. Its main function is to balance the up and down jump of the left and right wheels, so as to reduce the shaking of the vehicle and keep the vehicle stable. The V-shaped torsion beam is stamped from a round tube-shaped blank. The stamping process is to form two V-shaped surfaces inside and outside at one time, and then expand the port shape twice. Chinese patent ZL201410142309.4 disclosed a car tubular V-shaped torsion beam stamping process on July 30, 2014, and specifically disclosed the forming die and the expansion die. The operation is cumbersome, the production efficiency is low, and the formed product is a left-right symmetrical piece. It is difficult to distinguish the left-right direction in the subsequent laser cutting process, and it ...

Problems solved by technology

Chinese patent ZL201410142309.4 disclosed a car tubular V-shaped torsion beam stamping process on July 30, 2014, and specifically disclosed the forming die and the expansion die. The operation is cumbersome, the production efficiency is low, and the formed product is a left-right symmetrical piece. It is difficult to distinguish the left-right direction in the subsequent laser cutting process, and it is easy to reverse the parts. It is difficult to distinguish the left-right direction and the positioning of the parts is time-consuming and laborious. Greatly reduced cutting efficiency

In addition, when the processed torsion beam is welded with other parts, it is also necessary to manually distinguish the left and right directions to confirm the position of the weld seam, which not only increases the labor intensity of the workers, but also reduces the welding efficiency
