Abstract: The design of the loading material, tensile modulus and single composite processes Piercing Die Design. This paper briefly outlined the Stamping Die current development status and trends. Identify the product of a detailed analysis and the process. Stamping die design in accordance with the general steps to calculate and design the sets on the main mold parts, such as: Terrace die、Cavity die、Punch-holder、Dunn age、Die holder、Stripper、 Jig、Pin stop、Pilot and so on. Die-standard model planes, to choose a suitable stamping equipment. Design work on the parts and specifications will press for the necessary checking calculation. Punch and Die blanking punch were different plate fixed to facilitate adjustment gap; Punch and Die blanking die is used overall fixed plate.  Blanking punch contents is a derivative sales, and guarantee the work piece and the shape of the holes in the relative position accurately, improve processing accuracy. So the structure is designed to ensure reliable operation of die stamping products and the requirements of large-scale production.
Keywords: Combination die；Stamping die tool；Standard die set；Stamping Equipment；Check；Blanking.
