A Forming and Finishing Technology of Automobile Plastic Bumper Shell

Abstract

The invention relates to a molding and finishing process for automobile plastic bumper shells, which uses shell finishing equipment, and the shell finishing equipment includes a base, a fixed clamping device and a surface treatment device, and the rear of the upper end of the base is arranged There is a fixed clamping device, and a surface treatment device is arranged in front of the upper end of the base; the invention adopts the design of the clamping device without a driving source, and at the same time, through the automatic operation of the clamping device, it saves cost and manpower, thus solving the problem that is often difficult to achieve through a single drive. The multiple degrees of freedom of the bumper are restricted by the source, thereby causing multiple driving sources to fix the bumper. The invention solves the problem that the polishing device can not be uniformly and comprehensively through the reciprocating feeding and automatically adjusting polishing device. It is polished, resulting in poor polishing effect and reducing its aesthetics.

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.
