摘　　要：对厚度为0.8mm的H65黄铜连续拉深进行模拟分析和实际冲压效果对比分析,发现第五工序已经超过了材料成形极限,第六和第七工序的厚度急速变薄,无法达到品质要求。在此基础上,应用田口方法分析了凹模圆角、凸模圆角、凹模孔径、凸模直径、摩擦系数及冲压行程等因子对品质的影响,对各因子水准进行优化组合,冲压出合格产品。最后以第一工序为例探讨各因子对品质的影响度,得出冲压行程对成形厚度的影响达63%,凹模圆角rD为21%,摩擦系数为4%,其他因子的影响不是很大。It.first makes a simulation analysis and a comparative analysis of the actual stamping result for progressive drawing of H65 brass with 0.8mm thickness and finds that the fifth step has exceeded the forming limit for brass,the sixth and seventh steps rapidly become thin,which can＇t reach the quality standard,then analyzes some factors influencing the quality as die fillet,die diameters,friction coefficient and stamping stroke based on Taguchi method,and finally discusses the influence degree of each factor on the forming thickness taking the first step as an example and makes a conclusion that stamping stroke accounts for 63％,the female die fillet ro 21％,friction coefftcient 4％,while other factors have slight influence on the quality.
