Abstract:
This text main research design and manufacture process of the progressive die for the cover. This thesis applied professional curriculum theory and the actual production of knowledge, to cultivating and improving students' ability to work independently with doing a cold stamping mould design in practical training work, consolidated and expanded the course content of cold stamping mould design, grasps the methods and steps of cold stamping mould design, Master design basic skills of cold stamping mould, know how to analysis the parts manufaturability, determine the process. Through the comparison and combined with the actual production needs, understand the advantage of procedure, composite modulus, progressive die, understand the basic structure of mould, improve the ability of calculating and drawing, familiar with the specifications and standards, comprehensive review each subjects those related knowledge in the same time, and improving my independent thinking ability. Structure determine use progressive die which can make automation simple. And female die use insert, make mould changing, maintenance and maintain easier, then improve the work efficiency during the actual production. The main processes including that drawing，punching，flanging，pressure seal and blanking. The product process analysis, determine the stamping scheme, process calculation, templates design, parts design are discussed respectively in design.
Keywords : Blanking craft；Progressive die；CAD
