Abstract
The present design reports posite blanking punching Deep die, the basis of which is the knowledge about general blanking deep drawing .This paper analyzes the process of stamping mould, introducing the structure characteristics of the mould and assembly process.
The design is focused on both the analysis of the contact plate and the particular configuration design of die. According to the check with a great deal of reference details, it is a must to base on the technical analysis of the workpiece, then chose a best craft procedure to a given project. I Carried out the calculation and design process, such as determining process plan, layout and designing center of pressure calculation. The paper presents the ponents of the design conceptand and has a detailed analysis of the design process. This paper describes the content and purpose of the mold assembly, and has a detailed description of the mold assembly process.
Layout is reasonable or not can affect the economic utilization of materials, but also affect the mold structure, production, part quality, ease of operation and safety. At the same time, convex, concave mold structure has a great impact in the product quality. It is an important part of the design to design a reasonable and simple convex and concave mold under the premise of improving the economic efficiency and reducing costs.
