With the continuous development of Chinese industry, the mold industry has e increasingly important. The graduation project's mission is to take cover gasket stamping process analysis and design of the specific structure of the mold. By consulting the relevant literature, parts of the contact plate process analysis, selection and determine the conditions found at the given optimum solution, and carried out the calculation and design process, such as: choice of basic processes, determine their order, the number of processes and binations. Introduced the ponents of the design concept, detailed analysis of the design process, some ideas, and some non-standard parts to use features. Describes the design features of posite model, so the product quality to meet the design requirements. Then this basis, design the structure of the major parts stamping die. And in the design, the layout of parts described map, locate the design, calculation and blanking force center of pressure calculations..
Keywords: Take cover gasket Mold pound Die Stamping process

、特点及应用
冲压是利用安装在冲压设备(主要是压力机)上的模具对材料施加压力,使其产生分离或塑性变形,从而获得所需零件(俗称冲压或冲压件)的一种压力加工方法。冲压通常是在常温下对材料进行冷变形加工,且主要采用板料来加工成所需零件,所以也叫冷冲压或板料冲压。冲压是材料
