Based on the Cover of the stamping process and the deep drawing process, Comparative analysis of the process of forming three different stamping process (single processes, complex processes and continuous processes) confirm completion of a composite model blanking, drawing processes and punching process. On the cover of the cold stamping process, right after the Cover of the mass production, quality components, and the use of structural components of the analysis, research, in line with lower performance prerequisite to the identification of stampings, Stamping method used to complete the processing components, and a brief analysis of the blank shape, size, layout, the Conference Board, the number of Drawing, stamping processes in nature, number and sequence determination. For the process, the center of pressure, the die size and the tolerance of the calculation, design mold. Also analyzes the mold of the main components (such as punch and die and dump devices, drawing punch, slates, Punch plate, etc.) design and manufacturing, stamping equipment selection, punch-gap adjustment and establishment of a vital parts machining process. Die requirements set out a detailed list of parts, and gives a reasonable ass
