Compound molding process of integral automobile body metal stamping part

Abstract

The invention discloses a compound molding process of an integral automobile body metal stamping part. The automobile body stamping part comprises a stamping part main body part and a threaded part, wherein the stamping part main body part and the threaded part are integrated; and the compound molding process comprises the steps of trimming, drawing, extruding and contracting, heading, stamping through holes, heading and molding the top part, molding the main body part and the like. By adopting the metal compound molding technology, a metal material can be thickened uniformly at a part bearing part, the metallographic structure does not have cracks, and the requirement on part bearing test is met. The compound molding process shortens the development cycle of molds, reduces the working procedures of punching, improves the qualification rate of products, and improves the quality, the efficiency and the stability of the production process.

Description

technical field [0001] The present invention relates to a manufacturing process, in particular to a process for producing body stampings; in particular, a method of stamping an integrated body stamping with one or two threaded structural features using a progressive die Metal composite forming process. Background technique [0002] In the current design of automobile body stamping parts, the body part structure of the original stamping parts plus welding nuts (such as figure 1 shown), changed to structurally integrated parts (such as figure 2 As shown), this structural design reduces the parts production process, reduces the number of body parts, reduces welding energy consumption, and is more conducive to environmental protection. If the advanced production process is adopted reasonably, the production cost can be reduced. [0003] However, this kind of integrated body stamping parts needs to be tapped after the stamping is completed. In order to meet the process require...

AI Technical Summary

Problems solved by technology

This kind of material thickening design cannot be completed according to the general stamping method. The general stamping method will inevitably cause the material to become thinner when the material is deep-drawn; and the traditional stamping process is used to produce these parts. Generally, more than 10 Stamping process, the mold development cycle is long, there are many stamping processes, the product qualification rate is low and easy to fluctuate, and the quality of parts cannot be guaranteed
