Problems solved by technology

[0002] The flange connection seats of the automobile torsion beam are the left connection seat and the right connection seat respectively, and the molds are designed and produced separately. One-time forming processing is adopted, which requires a lot of mold investment, takes up a lot of equipment space, long production cycle, and difficult management. One-time forming processing is adopted. After forming The connecting support of the connecting support and the left and right vertical and horizontal beams do not cooperate well when welding, which affects the welding efficiency and welding quality

Abstract

The invention relates to an automobile torsion beam flange connecting base cold stamping production technology. The automobile torsion beam flange connecting base cold stamping production technology is characterized by comprising blanking, discharging, pre-forming, forming, cutting, punching and deburring. The product shape and size are good in consistency, the production efficiency is high, the cost is low, operation is simple, convenient and safe, post-process welding processing can be well met, fewer equipment, spaces and molds can be occupied, the material utilization rate is high, and theautomobile torsion beam flange connecting base cold stamping production technology has the application and popularization value.

Description

technical field [0001] The invention relates to a production method of automobile parts and components, in particular to a cold stamping production process of an automobile torsion beam flange connection seat. Background technique [0002] The flange connection seats of the automobile torsion beam are the left connection seat and the right connection seat respectively, and the molds are designed and produced separately. One-time forming processing is adopted, which requires a lot of mold investment, takes up a lot of equipment space, long production cycle, and difficult management. One-time forming processing is adopted. After forming The connection support of the joint is not well matched with the left and right longitudinal beams when welding, which affects the welding efficiency and welding quality. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide an automobile torsion to...
