Tubular V-shaped beam forming lower die assembly

Abstract

The invention discloses a tubular V-shaped beam forming lower die assembly. Cavities are symmetrically formed in the left end and the right end of a die base and communicated with each other through a transverse groove. A plurality of inserts which are sequentially spliced are fixedly arranged in the transverse groove. An inclined wedge block is arranged in each cavity of the die base. The opposite ends of the two inclined wedge blocks are each provided with a core shaft. A protrusion is integrally formed on the top face of the core shaft on the left side. The left end and the right end of the die base are each provided with a set of connecting plates which are each in a long-strip-shaped rectangular shape. Guide grooves are symmetrically formed in the front side and the rear side of the left end of the die base. Guide grooves are symmetrically formed in the front side and the rear side of the right end of the die base. The four guide grooves are distributed in a rectangular shape. Wear-resistant plates are attached to three inner walls of each guide groove and are steel plates. The tubular V-shaped beam forming lower die assembly is ingenious in concept, easy to implement and small in height and size; when a torsion beam is formed through the assembly, operation is easy and convenient, and production efficiency is high; the left direction and the right direction of the formed torsion beam can be easily recognized, and the torsion beam can not be put in the wrong direction in the subsequent procedure.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a lower mold assembly for forming a tubular V-shaped beam. 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 proce...

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
