旋转体拉深件表面积计算的新方法

A New Method of Calculating the Surface Area of Drawing Case of Rotor

旋转体拉深件表面积的计算是确定压延件毛料半径大小的依据,在冲压设计资料或教材中虽然有一些求旋转体表面积的公式和方法,但在实际应用中有局限性,且不方便,文中较详细地介绍了一种行之有效、使用简便的旋转体拉伸件表面积计算的新方法。

Calculating the surface area of drawing case of rotor is the basis of setting the radius of sheet metal blank.Although there some methods and formulae of calculating the surface area of rotor in the textbooks and the materials of the designs of stamping,it is inconvenient and limitative in practical use.This paper provides a good and effective but simple method for calculating the surface area of drawing case of rotor.
