中文摘要：
针对楔横轧轧制螺旋齿形轴类件的成形过程复杂、轧制力与轧制力矩等力能参数受轧制条件以及工艺参数的影响规律复杂等问题,采用DEFORM-3D有限元软件模拟楔横轧轧制螺旋齿形件的成形过程,分析不同工艺参数对轧制力和轧制力矩的影响规律。在H630楔横轧机上进行轧制实验,分别采用AD7202压力传感器和TorqueTrak9000扭矩仪测试轧制过程中轧制力和轧制力矩,进而验证各工艺参数对力能参数的影响规律。研究结果表明：轧制力和轧制力矩随轧制温度的升高而减小,随齿高变化率、轧制速度以及轧辊直径的增加而增加,其中,轧制温度对力能参数的影响最明显,齿高变化率和轧制速度的影响次之,轧辊直径的影响最小;进行轧机设计时,为了确保轧机承受足够大载荷,一般选取较低的轧制温度、较大的齿高变化率和较大的轧制速度。
英文摘要：
Based on the fact that forming spiral tooth shaft in cross wedge rolling is complex, and rolling condition and process parameters have great influence on mechanics parameters, such as rolling force and rolling torque, forming process of rolling spiral tooth shaft in cross wedge rolling （CWR） was simulated and the influence law of different process parameters on rolling force and rolling torque was analyzed using DEFORM-3D finite element software. The rolling test was made in the H630 rolling mill and rolling force and rolling torque were respectively measured using AD7202 pressure sensor and TorqueTrak9000 torque meter, and influence law of mechanics parameters was testified through experiment. The results show that the rolling force and rolling torque become smaller with the increase of rolling temperature and bigger with the increase of the three process parameters including change rate of tooth height, rolling speed and roller diameter. The rolling temperature has the greatest effect on mechanics parameters, change rate of tooth height and rolling speed take the second place, and roller diameter influences the least. To ensure large enough load, lower rolling temperature, larger change rate of tooth height, larger rolling speed must be selected when the rolling mill is being designed.
