精冲模具的设计主要从以下几个方面进行。 1.精冲压力精冲压力的计算是模具设计中十分重要的一个组成部分,其计算方法如下(图1): 总压力: P=P_1+P_2+P_3+P_4 冲裁力:P_1=L·S·τ·K; 压边力:P_2=c·P_1 反压力:P_3=f·P_1; 推件力:P_4=(0.07～0.1)P_1式中L——剪切线周长(毫米);τ——材料抗剪强度(公斤/毫米~2);
Fine blanking die design mainly from the following aspects. 1. Fine blanking pressure The calculation of fine blanking pressure is a very important part of the mold design. The calculation method is as follows (Figure 1): Total pressure: P = P_1 + P_2 + P_3 + P_4 Blanking force: P_1 = L · S · τ · K; Binding force: P_2 = c · P_1 Back pressure: P_3 = f · P_1; Pushing force: P_4 = (0.07 ~ 0.1) P_1 where L - circumference of the shear line in millimeters; τ - material shear strength (kg / mm ~ 2);
