Shell material used No. Q235A steel and thickness to ensure sufficient strength and stiffness. This deformation of material is suitable for manufacturing highperformance and deepdrawing products and more plex products shape. We carried out the parts of analysis, there is deep drawing, punching, cuttingedge series of processes. And production volume, and the works are of the size of the mutual relationship between the calculated and analyzed through the use of a stretching and punching the production of cuttingedge technology options to improve the utilization of materials. After pletion of the analysis of the mold design, convex and concave die part of the design work, there are the major ponents of layout and design of the structure, choose a suitable mold material. Also known as tensile drawing, rolling or extended. It is stretching the use of molds in the press under pressure, will be precut or blanking plate into the shape of a certain rough, threedimensional drawing made of hollow pieces of processing methods. It is stretching the use of molds in the press under pressure, will be precut or blanking plate into the shape of a certain rough, threedimensional drawing made of hollow pieces of processing methods. Prior the design of the die, the workpiece should be fully analysis. A correctly designed die structure and works process specifications can obtain the best economical benefit.
