Stamping die assembly for vehicle

Abstract

The invention discloses a stamping die assembly for a vehicle. Cavities are symmetrically formed in the left end and the right end of a die base, and the two cavities are communicated through a transverse groove; a plurality of sequentially-jointed inserts are fixedly arranged in the transverse groove, an inclined wedge block is arranged in each cavity of the die base, and the inclined wedge blocks are connected with a piston rod of an air cylinder; core shafts are arranged at the opposite ends of the two inclined wedge blocks, the core shafts and the corresponding inclined wedge blocks are fixed, and the core shafts can extend into a molding groove; stand columns are arranged at four corners of the top face of the die base and are cylinders, and the four stand columns are distributed in a rectangular shape; guide grooves are symmetrically formed in the front edge and the back edge of the left end of the die base, guide grooves are symmetrically formed in the front edge and the back edge of the right end of the die base, and the four guide grooves are distributed in a rectangular shape; and wear-resisting plates are attached to the three inner walls of each guide groove and are steel plates. The stamping die is ingenious in conception, reasonable in design, easy to implement, small in labor intensity of workers and high in efficiency; and operation for molding a torsion beam is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of dies, and in particular relates to a stamping die assembly for a vehicle. 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 is easy to ...

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
