给出了开式冷挤压动可容速度场及上限挤压力计算公式,讨论了主要参数对最佳模角的影响,理论分析结果得到实验验证。由理论及实验给出了可行模角及最佳模角。
The formula for calculating the moving speed field and the upper squeezing pressure of open cold extrusion is given. The influence of the main parameters on the optimum mode angle is discussed. The theoretical analysis results are verified by experiments. The feasible mode angle and the best mode angle are given by theory and experiment.
