Abstract：

For the scroll, based on the flow control forming (FCF) technology, two forming process schemes of adding back pressure damping and splitter cavity in the die were proposed, and the two forming process schemes were numerically simulated by software DEFORM-3D and verified by experiments. The simulation results show that with the back pressure structure, the metal fluidity of the scroll is better, but the required forming load is larger, and the equivalent stress and deformation amount of the die are larger. However, with the splitter cavity structure, the required forming load is smaller, the equivalent stress and deformation amount of the die are smaller, and the forming effect of the scroll is better. Combined with the simulation results, the precision die forging of the scroll was conducted by the die structure with the splitter cavity, and the quality of the scroll was good with well-filled end faces and without defects such as folding, crack and crush. Thus, the feasibility of the above forming process is verified.
