Stamping process and die design should be combined with the actual situation of the factory equipment, personnel, etc., from the quality of parts, productivity, production costs, labor intensity, environmental protection and security of all aspects of the production account, choose the advanced technology, economic rationality, safe and reliable use of the scheme and the mold to make stamping parts production guarantee the achievement of the technical requirements of design drawings on minimizing process costs punched and ensure safety in production.

With the rapid development of the mold, in modern industrial production, the mold has become the production of various industrial products indispensable process equipment. The graduation project is based on the study completed all courses conducted on machinery, comprehensive ability is my assessment, is the integrated use of my knowledge, but also on the knowledge I review and inspection.

This design is under the guidance of teachers serious, patient guidance of the lower mold economy, life of the mold, the production cycle, and the cost of production and other indicators to conduct a comprehensive, detailed analysis carried out under the design. Here, I express my heartfelt thanks for their teachings.

Key words:

Process analysis, mold technology demonstration program, process calculation, the selected processing equipment, manufacturing processes, and access to design data collection, preparation of design drawings and technical documents.
