Pipe type V-shaped torsion beam mold for two-way cylinder type vehicle

Abstract

The invention discloses a pipe type V-shaped torsion beam mold for a two-way cylinder type vehicle. Wedge blocks are respectively arranged in each molding cavity of a mold base; mandrels are respectively arranged at opposite ends of two wedge blocks; a convex hull is integrally formed on the top surface of the mandrel at the left side; stand columns are arranged at four corners of the top surface of the mold base, are cylinders, and are distributed in a rectangular manner; the lower end of each stand column is fixed with cushion blocks; the cushion blocks are fixedly connected with the mold base through bolts; one set of connecting plates is respectively arranged at the left and right ends of the mold base; each set of connecting plates is divided into front and back two parts; four connecting plates are distributed in a rectangular manner; the connecting plates are strip rectangles; guide grooves are symmetrically formed in the front and back edges of the left end of the mold base; guide grooves are symmetrically formed in the front and back edges of the right end of the mold base; four guide grooves are distributed in a rectangular manner; and wear resistant plates are respectively bonded on three inner walls of each guide groove, and are steel plates. The mold is reasonable in design, is convenient for torsion beam molding operation, is low in labor intensity of workers, and is high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a bidirectional cylinder type tubular V-shaped torsion beam mold for vehicles. 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...

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
