ABSTRACT
This article is designed punching, blanking, Progressive Die, Die practical examples of relatively simple structure, easy to use and reliable. Stamping die mainly of sheet metal forming have been separated or parts of the processing methods. Because the production of large quantities of mold manufacturing, mold and stamping products to ensure dimensional accuracy and quality of products,Die Design and Manufacture of the main mold design, taking into account the work of the process can meet the requirements of design, can be processed into qualified parts, as well as subsequent maintenance and storage, such as is reasonable. In the design of the gasket hole accuracy is more important outside the outer fillet size precision, not only have to consider so that the parts made to meet the job requirements, but also to ensure his life. the card order process, non-standard parts of the process of card processing technology.
Keywords:Blanking; drawing; punching; flip posite film
