Description

Automatic shaping device for die-casting workpiece

Technical Field

The utility model relates to the technical field of die processing tools, in particular to an automatic shaping device for a die-casting workpiece.

Background

In the casting process of the die casting, the die casting is die-cast and molded due to the influence of the process, the internal structure of the die casting contains a large amount of stress to be released, and the deformation condition of the die after the heat treatment is common.

The traditional shaping is performed manually, namely by hammering with rubber. The operation mode is easy to damage the surface of the product, the production efficiency is low, the reworking phenomenon is serious, the operation mode often becomes a bottleneck procedure for restricting mass production of the product, and the requirements of modern production on the quality and the production efficiency of the product cannot be met. Along with the rapid development of the manufacturing industry and the rising of labor cost in China, the traditional manual die casting shaping mode cannot be adapted to the development speed of the manufacturing industry gradually, and the self-adaptive shape-following shaping replaces manual shaping to become the necessary trend of the development of the manufacturing industry. The present utility model therefore results from this.
