| 摘 要： | 从理论上分析与论证了平砧拔长矩形截面毛坯只有砧宽比(W/H)一个工艺参数是不足的,认为应增加,个工艺参数料宽比(B/H),才能正确描述拔长毛坯中心区域的应力状态与有效控制锻件质量。该理论已被实验验证。

| Abstract: | About the theory of stretching a blank with rectangular cross section between flat tools.the argumentation is that only one parameter of the tool width ration (W/H) is insufficient to control the internal quality of large forging blank,another technical parameter blank width ratio(B/H) of forging blank should be added to it ,so that the internal stress state of elongated blank can be correctly described and the internal quality can be effectively controlled. This theory has been testified by experiment. |
