Abstract. To verify the feasibility of the synchronized forming of shape and inner hole for hollow axles and the influence of process parameters on the axial force in the continuous rolling section, a finite element model of the synchronized forming of shape and inner hole for hollow axles was established using finite element analysis software, and the forming process of hollow axle shafts was simulated. The results indicate that synchronized forming with shaped holes for hollow axle shafts is feasible. The axial stress in the continuous rolling section increases with the feed angle of the piercing roll. With the increase in the speed of the piercing roll, the axial stress in the continuous rolling section shows a trend of rapid increase followed by a slow increase. Moreover, as the conical angle of the disc-shaped rolls increases, the axial stress in the continuous rolling section generally increases.
