| Abstract: | To solve the problems of difficult forming, long process, and low material utilization of aviation turbine shafts, a piercing and rolling integrated forming method is proposed, which utilizes multi roll diagonal rolling technology to overcome the manufacturing problem of stepped large section shrinkage in outer surface processing and achieve a transformation from reduced material manufacturing to equal material manufacturing in inner hole processing. The forming process of nickel based high-temperature alloy GH4169 turbine shaft blank was numerically simulated using simulation finite element software. The metal flow law of the rolled piece during the forming process, as well as the changes in stress-strain field and force energy parameters, were analyzed. The feasibility of the new process was verified, providing theoretical support for the research of the new process. |
