根据实验结果分析了冷挤压凹模内壁压力P_凹、凸模压力P_凸和变形程度ε之间的关系;指出了P_凹P_凸的力学概念;给出了实验公式:P_凹=KεP_凸。
Based on the experimental results, the relationship between the pressure P_ in the cold wall and the P_ convexity and the degree of deformation ε in the inner wall of cold extrusion die is analyzed. The concept of P_convex P_ convex is given. The experimental formula is given: P _ Concave = KεP_ convex.
