开式模锻变形过程的理论分析

在合理建立开式模锻变形过程的物理模型的基础上,对其第二阶段的变形过程进行了系统的理论分析,首次建立了毛边槽桥部尺寸的设计准则。由理论分析所得变形力分布计算公式与实验结果相吻合。

The Theoretical Analysis on the Deformation Process of Open Die Forging

On the basis of properly building up physical model of deformation process of open die forging, this paper gives a systematic theoretical analysis on the second period of the deformation process and for the first time sets up the design criteria of the forging flash size. The distribution of deformation force calculated by the formula based on theoretical analysis coincides well with the experiment result.
