摘要
本文通过理论分析 ,推导出筒形件及带凸缘的筒形件第一次拉深的极限拉深系数的近似计算公式 ,并与多种材料实验值进行比较 ,表明此方法精确度较高。
By theory analyzing, this paper turns out the approximately calculate formulas of limit drawing modulus for cask shaped and flanged cask shaped mould. The theoretical analysis are in good agreement with experiment results of many kinds of materials.
