Square automobile chassis component forming technology

Abstract

The invention discloses a square automobile chassis component forming technology. The square automobile chassis component forming technology comprises pre-forming and forming. According to a square automobile chassis component structure, a square automobile chassis component body is included, and the square component body comprises a left square component single piece and a right square componentsingle piece which are symmetrically arranged. The left square component single piece or the right square component single piece comprises a bottom provided with a U-shaped notch, the periphery of a bottom plate vertically extends to form a side face, and the R angle formed by the side face approaches the right angle. The original square face is pre-formed into the hook face shape firstly, the arcface formed through pre-forming is formed into the square face with the R angle approaching the right angle, then, the bottom notch is punched, and a final product is obtained. The square automobilechassis component forming technology has the beneficial effects that a series of problems that due to high material strength, large material thickness, the small R angle and other design of square closed products, during direct forming, cracking, material stacking, die scrapping and the like are caused can be effectively solved.

Description

technical field [0001] The invention relates to a processing method of an automobile chassis part, which belongs to a cold stamping forming process, in particular to a forming process of a square automobile chassis part. Background technique [0002] In modern society, with the strengthening of people's awareness of environmental protection, people tend to think more about environmental protection and energy saving in production and life, which makes the design of products more complicated to meet and meet the original quality requirements, but this design makes The difficulty of production has increased, and many products cannot be processed by traditional techniques. [0003] For example, more and more automotive chassis parts make the shape of the product more complex and more difficult to process, and the problem of the shape of the product is also highlighted. Especially for square automobile chassis parts, due to the particularity of its shape, high material strength,...

AI Technical Summary

Problems solved by technology

Especially for square automobile chassis parts, due to the particularity of its shape, high material strength, thick material thickness, and small R angle, a series of problems such as cracking, stacking, and mold scrapping occur during direct molding. The existing stamping process has problems such as inability to form, extrude, pile up, crack, and hidden cracks. For example, it is impossible to form products directly according to the current stamping process; most of them use casting molding; some also use cold stamping forming process , but the preparation process is cumbersome. In order to avoid the above-mentioned technical problems, four forming steps are often required: first forming a certain angle, then forming a certain angle, then forming a certain angle, and finally forming a final product; loss, and the consistency of the obtained product cannot be guaranteed, and the product also has different degrees of process creases on the product surface due to more processes (there are similar problems in the factory); and if you want to form a square closure material at one time, it will be difficult to walk Stacking and extruding materials at the corners of the material and R will cause uneven mold gaps. This will not produce many products. The thicker parts of the product will directly cause the surface treatment of the mold to be worn, the product will be rough, and further will cause the mold to crack and be scrapped.
