在小孔冲模设计中,一般将细长凸模设计成台阶型式。但怎样进行凸模的稳定校核,从而确定其结构尺寸,下面仅作一些粗浅的理论分析和计算。一、计算基础对于细长凸模的稳定校核,可根据不同的支承方式,由材料力学中的欧 In the hole die design, the general design of the elongated punch into a step type. But how to conduct a stable check of the punch to determine the size of its structure, the following only for some superficial theoretical analysis and calculation. First, calculate the basis For the stability of slender check, according to different support methods, materials mechanics in Europe
