Forming die assembly

Abstract

The invention discloses a forming die assembly. The forming die assembly is characterized in that an inclined wedge block is arranged in each cavity of a die holder; core shafts are arranged at the opposite ends of the two inclined wedge blocks; a boss is integrally formed on the top surface of the core shaft on the left; the boss is near the right end face of the corresponding inclined wedge block; upright posts are arranged at the four corners of the top surface of the die holder; the lower ends of the upright posts are fixed to cushion blocks; a group of connecting plates is arranged at each of the left end and the right end of the die holder; the connecting plates adopt a long rectangle shape; two front-back rows of limiting blocks are arranged in the middle of the top surface of the die holder; the limiting blocks are hollow two-section short columns which are small in the upper parts and are large in the lower parts; guide grooves are symmetrically formed in the front and back sides of the left end of the die holder, and are symmetrically formed in the front and back sides of the right end of the die holder as well; abrasion resistant plates are pasted on the three inner walls of each guide groove; and the abrasion resistant plates are steel plates. The forming die assembly is easy to implement, simple in structure, and high in production efficiency, and a formed torsion beam easily recognizes the left and right directions.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a molding die 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 it is easy to reverse the p...

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
