1、XXXX 大学毕业设计（论文） 环形铰链卡子模具设计环形铰链卡子模具设计 摘摘 要要： 本设计为环形铰链卡子模具设计和鼓形滚子挤压试验。 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，即 该工件需要落料-冲孔复合模和弯曲模来完成。然后通过工艺设计计算，确定排样方式。 计算冲裁力和压力中心，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，其中在结构设计中，主要对凸模、凹模、凸凹模、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或选取，对模具主要零件的加工工艺规程进行编制， 对压力机进行校核，绘制模具总装图，及零件
2、图，最终完成模具设计。 关键词关键词：冲压、模具、凸模、凹模、凸凹模。 XXXX 大学毕业设计（论文） II The Cold Stamping Die Design of a Ring Hinge Bands Abstract: The design is about the cold stamping die design of a Ring hinge bands and the extrusion trial of drum products. According to the size, materials, mass production of the produc , the f
3、irst part is to analysis the process of the part . so the program of blanking process and die structure has been confirmed. As a results, blanking-punching composite mould and bending mould are used to produce the parts. Then based on the process design calculations, the stock layout design can be e
4、nsured. It is needed to carry on the blanking force and the center of pressure computation, according to which the press can be choosed. Calculating the punch and die cutting edge size and tolerances, then design and selection the parts of die. During the structural design, it is mainly about the design of the punch, die, punch and die, positioning parts, unloading and ejecting devices, mold, pressing equipment, fasteners, and so on. Press need to be checked, then draw the drawings and asse
