Abstract
This design has two sets of singleworking dies. After consulting the data,we should first analyze the parts. After process analysis and comparison, forming, blanking and punching processes are adopted. The type of press is determined through calculation of blanking force, top load and unloading force. Then analyze the type of mold for stamping parts and choose the mold that needs to be designed. The design process of each part of the die is expressed after the mold type is designed. In the first part of the document, mainly described the development of stamping die, explained the importance of stamping die and the significance of this design, followed by the process analysis of stamping parts, completed the determination of the process plan. In the second part, the design of the layout of parts is completed, and the material utilization ratio is calculated. Then the blanking force calculation and the design calculation of theworking part of the blanking die provide the basis for selecting the stamping equipment. Finally, the design of the main parts and the selection of the standard parts provide the basis for the design of the mold drawing and mold forming, and provide the basis for the size of the assembly drawing. Each part drawing and assembly drawing of the die are drawn through the previous design plan. This design describes the structure design andworking process of the stamping compound die. The die has reliable performance and stable operation, improves product quality and production efficiency, reduces labor intensity and production cost.
