| The aim of this work was to study the feasibility of hollow stepped shaft forging by warm extrusion. Accord- ing to the structural property of the hollow stepped shaft, the forming program was defined, and Deform-3D technique was used to perform finite element numerical simulation for the forming process, and then the feasibility of the process was validated. The numerical simulation results showed that the forming result was good, without any unfulfilled defects and folding defects, and the dimensional precision was high. In conclusion, hollow stepped shaft meeting the dimensional requirements was obtained by warm extrusion forming process. The forming process was stable and reliable, and the forming technology was feasible. |
