The design of the mold parts through further training a designer integrated use of multi-disciplinary theories and to create, the ability to solve practical problems encountered in the production of too much trouble. The research stent precision stamping die design, through analysis and comparison of the work piece is determined using progressive die, bent mold production. Progressive Die adoption benefit is that the work can increase productivity and save manpower, material resources, can be automated machining as soon as possible. Coupled with the higher feed-processing operation at a convenient time, to ensure the safety of construction workers, more suitable for mass production. However, we must consider the use of progressive die strip of pinpoint problems, as well as progressive die structure complex work piece machining time is longer, higher processing costs of the work piece and other issues. Therefore, every reason for a comprehensive, targeted to carry out progressive die, bent to explore research topics are particularly valuable. The contents of this subject includes determining progressive die and bending die strip layout, punch design, die design, punching force calculation, select the punching mechanism to determine the pressure center of stamping die edge siz
