A single stage hot forging process and die set of alternator poles
A single stage hot forging process and die set of alternator poles are put forward in this paper, the heated billet can be forged by only one press in a special die set, which has a moveable mandrel and ring die. The process is analyzed by finite element method(FEM) and experiment. The effects of mandrel on the mode of metal flow and forging load are discussed. The result shows that a well-shaped product can be forged successfully using a lower forging load than that of conventional precision forging.
