摘要
本设计进行了冲圆孔、冲槽、落料连续模的设计。文中简要概述了冲压模具目前的发展状况和趋势。对产品进行了详细工艺分析和工艺方案的确定。按照冲压模具设计的一般步骤,计算并设计了本套模具上的主要零部件,如:凸模、凹模、凸模固定板、垫板、凹模固定板、卸料板、导尺、挡料销、导正销等。模架采用标准模架,选用了合适的冲压设备。设计中对工作零件和压力机规格均进行了必要的校核计算。此外,本模具采用始用挡料销和圆形挡料销挡料。落料凸模内装有导正销,保证了工件上孔和外形的相对位置准确,提高了加工精度。如此设计出的结构可确保模具工作运行可靠和冲压产品大批量生产的要求。

ABSTRACT
This design carried on has flushed circle hole, flushes the trough, falls the material continual mold the design. In the article has briefly outlined the ramming mold at present development condition and the tendency. Has carried on the detailed craft analysis and the craft plan determination to the product. According to general step which the ramming mold designs, calculated and has designed on this set of molds main spare part, for example: The raised mold, the concave mold, the raised mold dead plate, the backing strip, the concave mold dead plate, unloads, leads the ruler, keeps off the material to sell, to lead is selling and so on. The mold frame uses the standard mold frame, has selected the appropriate ramming equipment. In the design has carried on the essential putation to the ponents and the press specification. In addition, this mold uses the beginning with to keep off the material to sell with the circular keeps off the material. the concave mold and fall
