门锁盖冷冲压工艺及模具设计
摘要：本设计为一综合类零件的冷冲压模具设计，根据设计零件的尺寸、材料、批量生产等要求，首先分析零件的工艺性，确定冲裁工艺方案及模具结构方案，然后通过工艺设计计算，确定排样和裁板，计算冲压力和压力中心，初选压力机，计算凸、凹模刃口尺寸和公差，最后设计选用零部件，对压力机进行校核，绘制模具装配图，以及对模具主要零件的加工工艺规程进行编制。其中在结构设计中，主要对凸模、凹模、定位零件、卸料与出件装置、模架、冲压设备、紧固件等进行了设计，对于部分零部件选用的是标准件，就没深入设计，并且在结构设计的同时，对部分零部件进行了加工工艺分析，最终才完成这篇毕业设计。

Door lock cover cold stamping technology and die design
Abstract：This design is a comprehensive parts of cold stamping die design, design according to the size of the parts, materials, such as batch production, first of all, analysis technology of components, stamping process and die structure scheme is determined, and then through the process design and calculation, determine the layout and the cutting board, the calculated pressure and pressure center, primary press, convex and concave die cutting edge dimension and tolerance, choose zero, parts design, finally to check of press, drawing die assembly drawing and main components of the machining process planning and die.In structure design, mainly to the punch, concave die, positioning parts, unloading and out of a device, formwork, stamping equipment, fasteners and so on has carried on the design, selection for some parts are standard parts, no thorough design, and in structural design at the same time, analyzed the processing technology of some parts, finally completed the graduation design.
