锻造铝合金轮毂由于其优越的性能成为轮毂制造业发展的必然趋势。摆动辗压制坯工序是锻造铝合金轮毂生产工艺中一步重要的工序。本文使用DEFORM-3D软件对锻造铝合金轮毂摆动辗压制坯过程进行数值模拟,考察了主要工艺参数对成形过程的影响,并确定了合理的始锻温度480℃和压下速度10 mm.s-1。用已经确定的成形参数考察了Φ558.8 mm铝合金轮毂制坯工序成形力的大小为2335 kN,与实验结果2362 kN非常接近。数值模拟结果可以为开发该工序设备确定主参数提供理论依据。

As forging Al-alloy wheel hub has a good performance,it has been the inexorable trend of wheel hub manufacturing development.Swing-rolling technology is an important process.Numerical simulation of swing-rolling technology was performed using the software DEFORM-3D.The influence of main technique parameters in the forming process was researched and the appropriate initial forging temperature of 480 ℃ and hold down speed of 10 mm·s-1 were determined.Based on the determined forming parameters,the forming force of Φ558.8 mm Al-alloy wheel hub was studied and it was about 2335 kN which was coincident with the experimental result of 2362 kN.Numerical simulation result can be regarded as the theoretical basis for defining main parameters when these series of machines are developed.
