Sažetak

In the process of TRSR hollow axle, there is metal reflow on the surface of the rolled piece, which greatly reduces the forming accuracy of the rolled piece. To solve this problem, it is necessary to study the metal reflow law of axle body. First, the flow law of metal on the surface of rolled piece is obtained by point tracking method. Moreover, the effects of process parameters on the metal reflow degree of axle body are carried out, and the influence law of process parameters on the metal reflow degree of axle body is obtained. Finally, by comparing the results of the experiment and the simulation, the reliability of the simulation is proved.
