Abstract

As a novel metal forming process, cross-wedge rolling (CWR) is widely used in the manufacture of large axles in the rail transportation industry. When the forming process of the axle is studied, its formability becomes one of the key issues in the metal forming process. This paper takes LZ50 axle steel as the research object. Through the application of ANSYS finite element simulation software, combined with previous research and literature, a dynamic simulation of the rolling process is carried out, and the stress, strain and temperature field of the axle steel in the forming process are analysed. The results show that with the deepening of rolling, the plastic deformation of the metal becomes increasingly obvious. When the finishing section is reached, the temperature on the surface and inside the rolled piece reaches relatively uniform distribution.
