Pneumatic vehicle V-shaped torsion beam molding device

Abstract

The invention discloses a pneumatic vehicle V-shaped torsion beam molding device. Molding cavities are symmetrically formed in the left and right ends of a mold base; inclined wedges are respectively arranged in the two molding cavities; the inclined wedges at the left and right edges are symmetrical; mandrels are respectively arranged at opposite ends of the two inclined wedges, are fixed with the corresponding inclined wedges, and can extend into molding grooves; front and back two rows of limiting blocks are arranged at the middle part of the top surface of the mold base; the limiting blocks are two-section type hollow short columns with small tops and big bottoms; screws are inserted in the centers of the limiting blocks for fixing with the mold base; guide grooves are symmetrically formed in the front and back two edges of the left end of the mold base, and guide grooves are symmetrically formed in the front and back edges of the right end of the mold base; and wear resisting plates are respectively bonded on three inner walls of each guide groove, and are steel plates. The pneumatic vehicle V-shaped torsion beam molding device is skillful in concept, reasonable in design, easy to be implemented, small in height size and low in production cost; and a molded torsion beam is easy to identify a left-right direction, so that the positioning of the torsion beam in subsequent procedures is convenient.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a pneumatic vehicle V-shaped torsion beam forming device. 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 proces...
