摘要：

主要介绍了1600 mm辊锻机及其在轨道交通用车轴生产中的应用。现场实验结果表明：1600 mm辊锻机完成冷调和热调后，设备的能力、可靠性得到了有效验证，各项性能参数指标均达到设计要求；车轴采用精密辊锻成形，质量良好，满足锻件设计要求，各项力学性能指标均满足要求，表明车轴采用精密辊锻成形是可行的；与快锻、径向锻生产车轴的对比结果显示，车轴采用精密辊锻成形，生产效率高、材料利用率高且后续机加工量小，经济效益比较显著。1600 mm辊锻机的研发及在轨道交通用车轴生产中的应用对一些大型轴类件的精密辊锻成形有很好的示范作用。

1600 mm roll forging machine and its application in production of axles used in rail transit were mainly introduced. The results of field experiments show that after the cold and hot tests on 1600 mm roll forging machine are completed, the ability and reliability of the equipment are verified, and the performance parameters and indicators reach the design requirements. The axle is formed by precision roll forging, and the quality is good, which meets the design requirements of forgings, and the requirements of various mechanical properties and indicators, indicating that precision roll forging for axle is feasible. The comparison results with axles produced by fast forging and radial forging show that the precision roll forging of axles has high production efficiency, high material utilization rate and less follow-up machining allowance, and its economic benefits are relatively significant. Thus, the research and development of 1600 mm roll forging machine and its application in the production of axles used in rail transit play a good exemplary role on the precision roll forging for some large shaft parts.
