Abstract
Stamping die - in cold stamping process and material (metallic and non-metallic) into parts (or semi-finished) is a kind of special craft equipment, called cold stamping mould (known as cold die). Stamping is at room temperature, pressure machine using installed in the mold of material, make its produce pressure separation or plastic deformation, and obtain a pressure parts processing methods.
Based on the stamping process of fork is analysed in detail, decided to adopt the stamping part is the fork of the rectangular shape and hole. Through the comprehensive consideration of the workpiece, the production process and adopt composite modulus structure inversion type blanking, blanking dies.the and punching punch in the composite modulus, feeding and upper punch mould in the composite modulus, once after cutting, workpiece through pushing a device was introduced from the concave die, and waste from intensive drops. In the mould parts in the choice to hedge pressure, punch and die, the size of the calculated through the manual and experience in mould design inquires the size of each component determined, and the strength of the punch. Finally, the drawing die layout and various parts graph.
