Abstract：

In order to obtain qualified upper cover part, its structure, forming difficulties and process content were analyzed, and eight production processes including blanking and drawing, boss punching, edge turning, punching, reshaping and embossing were determined. Then, combined with the knowledge and experience of stamping die design, a set of compound die and single operation die were designed, and each manufacturing process and die working process were described in detail. To ensure the quality of edge turning, a set of edge turning fixture was designed, and the working principle of fixture was described in detail. The mass production shows that the manufacture technology, forming method and process sequence of upper cover part conform to its structural characteristics, the products fully meet the requirements of drawing, and the quality is stable and the rate of defective products is low. In addition, these dies have the advantages of compact structure, convenient operation, low manufacturing cost and good interchangeability, the fixture of edge turning is easy to operate, the workpiece is disassembled quickly, and the clamping force is adjustable, which solves the problem of clamping thin-walled parts and provides a reference for the production of similar structural parts.
