Forming finish machining process for automobile plastic bumper shell

Abstract

The invention relates to a forming finish machining process for an automobile plastic bumper shell. Shell finish machining equipment is adopted, and the shell finish machining equipment comprises a base, a fixed clamping device and a surface treatment device. The fixed clamping device is arranged behind the upper end of the base, and the surface treatment device is arranged in front of the upper end of the base. Through the design of the clamping device without a driving source and the automatic operation of the clamping device, the cost and manpower are saved, so that the problem that multiple degrees of freedom of a bumper are often difficult to limit through a single driving source, and consequently the bumper is fixed by multiple driving sources is solved. By means of the polishing device capable of achieving reciprocating feeding and automatic adjustment, the problems that the polishing effect is poor, and the attractiveness is lowered due to the fact that polishing cannot be evenly and comprehensively conducted are solved.

Description

technical field [0001] The invention relates to the technical field of automobile bumper production, in particular to an automobile plastic bumper shell forming finishing process. Background technique [0002] The front and rear ends of the car are equipped with bumpers, which not only have a decorative function, but more importantly, are a safety device that absorbs and eases external impact, protects the car body and protects the car body and occupants. With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, automobile bumpers, as an important safety device, are also on the road of innovation. At present, in addition to maintaining the original protective function, the front and rear bumpers of automobiles also need to pursue harmony and unity with the shape of the car body, and pursue their own lightweight. The front and rear bumpers of cars are made of plastic, which are called plastic bumpers. ...

AI Technical Summary

Problems solved by technology

[0003] The following problems often exist in the process of finishing the plastic bumper shell. First, because the bumper is a special-shaped part, when it is clamped, it is often difficult to control the multiple degrees of freedom of the bumper through a single driving source. Therefore, multiple driving sources are used to fix the bumper, which greatly increases the production cost of the factory; 2. Since the bumper is a special-shaped part, when polishing the surface of the bumper, it is often not evenly and comprehensively It is polished, resulting in poor polishing effect and reducing its aesthetics.
