用实验的方法找出阶梯孔法兰件辗扩成形中金属的流动规律,分析了该类锻件在辗扩变形时出现缺陷的原因,提出了消除缺陷的措施,给出了辗扩孔型设计和计算辗扩用最佳毛坯的方法,对使用辗扩工艺生产阶梯孔法兰类工件具有一定的指导意义。
By means of experiment, the flow rule of the metal in the step-hole flange part was found. The reason of the defect appeared during the rolling deformation was analyzed. The measures to eliminate the defect were put forward. The design and calculation Rolling with the best method of roughing, the use of rolling process step hole flange type of workpiece has a certain significance.
