摘要：

针对精冲机复杂、瞬时、重载的受力条件和精冲模的高精度对设备刚度提出的高要求,设计精冲机机身结构,建立精冲机机身结构有限元分析模型;根据精冲机机身的上横梁、立柱、下横梁3部分的有限元分析结果,提出机身结构的改进方案并进一步模拟分析;得到了更优的结构方案,改进了精冲机机身结构;改进后的机身刚度和强度均满足要求,最后绘出优化的精冲机机身结构。

For the fine blanking machine's complexity,instantaneous,heavy stress conditions and fine-blanking die's high-precision,which put forward a high stiffness requirement of the equipment,the structure of fine-blanking machine's frame was designed,and its finite element analysis model was established,then based on the result of the fine blanking machine's entablature,crutch and lower separator,a modified scheme of frame structure was put forward and further simulation was carried out to get the best scheme and improve the structure of fine blanking machine's frame.After the modification,both the stiffness and the strength met the requirements of frame structure,and finally the most optimized frame structure of fine blanking machine was drawn.
