It is also one of the most important developmental foundations for all departments of country economy. The progressive die is a kind of complex and precise forming die. It possesses many advantages such as high efficiency, accuracy and long life. The sheet metal stamping forming is important metal processing methods have been widely used industrial production areas. Mold is the basis for industrial production processes and equipment. Mold production of work pieces by the available high-precision, high-complexity, high consistency, high productivity and low consumption, other manufacturing methods could be compared. Blanking process analysis of fender is completed and blanking proposal is decided, and designing and selecting of main parts of die are showed. Based on Solidworks, three-dimensional parameterization molding designing for fender is completed with technology of three-dimensional parameterization designing and model building, and dimensions of die can be changed as required; by virtual assembly, structure of die and relation of mutual alignment can be observed and analyzed directly; the product rate of development is accelerated and product development cycle is shortened.
