Abstract：

The metal flow and deformation rules in the roll forging process have not been fully mastered, and the process design mainly depends on the experience. Thus, the selection of shape and size for billet has a great influence on the roll forging products. For a new type of rotary blade, three kinds of billets with different shapes and sizes were designed by experiences, and the roll forging process of rotary blade was simulated by the FEM soft Deform-3D. Then, a reasonable billet was selected, and the metal flow rule during the roll forging process was analyzed. Furthermore, the load of roll forging dies was studied and the torque of roll forging was calculated. According to the results of simulation, the designed shape and size of billet were revised, and then the trial sample of rotary blade was manufactured, which was consistent with the simulation results. The result shows that the numerical simulation offers an effective reference for the roll forging process and billet selection of rotary blade.
