摘要

针对准双曲面齿轮小轮热滚轧成形过程进行分析，发现在热滚轧过程中会出现“突耳”等缺陷。利用控制变量法进行热滚轧数值模拟仿真，对模具齿轮的转速、进给速度、摩擦因数、温度等因素对滚轧质量的影响规律进行了研究。通过对仿真加工过程以及滚轧试验结果进行分析，得到了工艺参数对滚轧成形的影响规律，确定了合理的工艺参数组合。热滚轧台架试验表明，合理的工艺参数匹配，能够避免“突耳”、材料流动不均匀等成形缺陷的产生。

Abstract

A theoretical analysis of the forming defect in the hot rolling forming process of a hypoid gear wheel is performed. It is found that defects occur during the hot rolling process， such as “lugs”. The control variable method is used to carry on the numerical simulation test of hot rolling， the influence law of the speed of the mold， the feed speed of the mold， friction coefficient， temperature， etc on the rolling quality are studied. Through the analysis of the simulation process and the simulation results， the influence law of the process parameters on the roll forming is obtained， and the reasonable combination of process parameters is ultimately determined. The hot rolling bench experimental results show that the reasonable process parameter matching can indeed reduce the forming defects， such as lugs and uneven material flow.
