ABSTRACT The main contents of this manual includes two aspects, the first aspect is the development prospect and trend of mold market, stamping technology and the meaning of the future direction of development. Roughly second aspects I design is a reducer required cover section, design and manufacture process of punching compound die, in which contains a formulation of the manufacture process, calculation of end cap punch mold needs in the die and the cutting edge dimension, punch checking can withstand the pressure and verification and so on. This press cover parts need using the stamping method to produce the composite mold according to the size structure and yield of the end cover the use of compound die. The die insert structure, in order to save steel for processing and avoid stress concentration problems, the fixed structure often use screws to fix the structure, but there are also disadvantages, the structure must be The insert size of the blade, the clearance between punch and die are determined and guarantee. Therefore, the structure for each spell the size of the blocks have special requirements of strict size.
