1、机器垫片冲压模具设计摘要现代工业发展中,模具占有举足轻重的地位,由模具生产出的产品具有成本低,效率高,质量好等优点,因此模具在许多领域得到广泛应用。该论文介绍了落料、冲孔连续模的设计。文中首先简要概述了冲压模具目前的发展状况和趋势。接着对产品进行了详细工艺分析和工艺方案的确定。并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、卸料板、导料板、始冲挡料销、导正销等。本论文中的模具模架采用标准模架,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。模具的冲孔和落料凸模用相同的固定板固定;冲孔凹模和落料凹模则采用整体式。导正销
2、单独固定在凸模固定板内,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。关键词:连续模,标准模架,冲压设备,冲孔,落料Adjusting Washer Blanking Die DesignABSTRACTIn the modern industry development, the die holds of the pivotal status, productsproduced by the dies have advantages of lower cost, higher efficiency better qual
