It has high productivity, low processing cost, high material utilization ratio, product size precision and stability advantages.Stamping die design take full advantage of the function of characteristics of mechanical presses, stamping, and high production efficiency in the blank under room temperature conditions, and significant economic benefits. On the graduation design, the design is in the function keys of the stamping process preparation. From the forming process of rationality set out, first analyzes the parts of the structure precision characteristics, to meet the stamping processing accuracy based on full consideration of cost savings, if the use of progressive die production, greatly improve production efficiency, is suitable for large batch production. Or the selection of a single process model will be extremely difficult to complete or selection of compound die will be more difficult to process, reach the production requirement. Thus to determine the selection of progressive die forming. Machining process for: punching, cutting edge, edge cutting, bending, blanking. At the same time through further analysis, determine the total structure of the mould and stamping
