1、 0 摘要 本次主要设计了一套冲孔、落料、弯曲的模具。经过查阅资料，首先要对零件进 行工艺分析，经过工艺分析和对比，采用冲孔落料工序，通过冲裁力、顶件力、卸料 力等计算，确定压力机的型号。再分析对冲压件加工的模具适用类型选择所需设计的 模具。得出将设计模具类型后将模具的各工作零部件设计过程表达出来。在设计说明 书的第一部分，主要叙述了冲压模具的发展状况，说明了冲压模具的重要性与本次设 计的意义，接着是对冲压件的工艺分析，完成了工艺方案的确定。第二部分，对零件 排样图的设计，完成了材料利用率的计算。再进行冲裁工艺力的计算和冲裁模工作部 分的设计计算， 对选择冲压设备提供依据。 最后对主要零部件的
2、设计和标准件的选择， 为本次设计模具零件图的绘制和模具的成形提供依据，以及为装配图各尺寸提供依 据。 关键字：关键字：冲孔；落料；弯曲；复合模具；弯曲模具；冲压设备。 0 ABSTRACT This design carries on blanking , the piercing progressive dies design .The article has briefly outlined the press die at present development condition and the tendency. It has carries on the detailed craf
3、t analysis and the craft plan determination to the product. According to general step which the press die designs, calculated and has designed on this set of mold main spare part, for example: The punch, the matrix, the punch plate, the backing strip, the matrix plate, stripper plate, stop pin, pilo
4、t pin and so on .The die sets uses the standard mould bases, has selected the appropriate press equipment .In the design has carries on the essential examination computation to the working elements and the press specification .In addition, this die employs the finger stop pin and the hook shape stop pin .The mold piercing and blanking punch are fixed with the different plates separately in order to coordinate the gap conveniently ; The piercing matrix and blanking matrix are fixed by the overall
