The stents for SGCC materials, materials are resistant to corrosion; Easy formability and good spot welding sex, material thickness t = 1.2 mm. The forming process of stents are punching the material and bending forming. In the design process, first to the support of the stamping technology are analyzed, and the stamping process program and determine the mould structure types, and through the necessary stamping process parameters are calculated. Mould positioning parts, unloading and push a device design, the standard formwork and guide the selection of parts, mould of the main parts manufacturing process and the process of the assembly process, and work principle of the die for analysis, including the total assembly, try die mould, lubrication and mold use, etc. In the graduation design using a computer aided design (CAD) drawing mould main parts of the die assembly drawings always chart and, using a numerical control processing, numerical control line electric processing advanced processing technology.
