Abstract：

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.
