摘要：

以涡旋盘动盘为研究对象，基于流动控制成形技术提出在凹模中分别添加背压阻尼和分流腔的两种成形工艺方案，通过DEFORM-3D软件对两种成形工艺方案进行数值模拟和试验验证。模拟结果表明：采用背压结构，涡旋盘金属的流动性更好，但所需成形载荷较大，且凹模的等效应力和变形量较大；采用分流腔结构，所需成形载荷更小，凹模的等效应力和变形量更小，同时涡旋盘的成形效果较好。结合模拟结果，利用添加分流腔后的模具结构进行涡旋盘精密模锻成形，得到的涡旋盘质量较好，端面填充饱满，未出现折叠、裂纹、压伤等缺陷，验证了此成形工艺的可行性。

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.
