本文通过实验研究， 确定了轮槽中坯料变形温度的分布， 在此基础上， 考虑变形温度和变形速度对流动应力的影响， 采用逐次单元法推导出轮槽中接触应力的计算公式， 首次确定了轮槽中塑性变形区的几何参数和轮槽间隙区中溢余分布的几何形态， 为连续挤压设备的设计提供了理论依据。
In this paper, through the experimental study, the distribution of the deformation temperature of the billet in the wheel well is determined. Based on this, the influence of the deformation temperature and deformation velocity on the flow stress is considered. The formula for calculating the contact stress in the wheel well is deduced by successive element method. The geometrical parameters of the plastic deformation zone in the wheel groove and the geometry of the surplus distribution in the clearance area of the wheel groove provide the theoretical basis for the design of the continuous extrusion equipment.
