摘要
用能量法推导出两片罐变薄拉深时,毛坯变形抗力最小条件下的凹模锥角表达式。将所计算的凹模锥角与其他方法求得的锥角进行了比较和实验验证,其结果更接近实测数值。这种计算方法可以为变薄拉深模具设计提供一定的参考。
It has been derived a formula of cone angle of femal die when two-piece cans thinned and drawn under the condition of the minimum resistance of deformation by using the energy method.Compared with the results from other methods,this calculation result was more close to the measured value.This formula may have certain significance in the design for thinning drawing dies.
