Pneumatic torsion beam stamping die holder assembly

Abstract

The invention discloses a pneumatic torsion beam stamping die holder assembly. An inclined wedge block is arranged in each cavity of a die holder. The opposite ends of the two inclined wedge blocks are each provided with a central spindle. A convex hull is formed integrally on the top face of the left central spindle and is close to the right end face of the corresponding inclined wedge block. The four corners of the top face of the mold holder are provided with stand columns which are cylinders. The four stand columns are distributed in a rectangular manner. The lower ends of the stand columns are fixed to cushion blocks. The left and right ends of the die holder are each provided with a set of connecting plates. The connecting plates are in a long-strip rectangular shape. Front and rear rows of limiting blocks are arranged in the middle of the top face of the die holder. Each limiting block is a big-end-down two-section hollow short column. A screw penetrates the center of each limiting block to be fixed to the die holder. The pneumatic torsion beam stamping die holder assembly is simple and compact in structure, small in height size, easy and convenient to operate and high in production efficiency, the left-right direction of a formed torsion beam can be easily recognized, the torsion beam is conveniently positioned in the follow-up process, and the phenomenon that the torsion beam is placed reversely is avoided.

Description

technical field [0001] The invention belongs to the technical field of dies, and in particular relates to a pneumatic torsion beam stamping die seat assembly. 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 ...

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
