| 中文摘要: |
| 在“碳达峰、碳中和”背景下，我国氢能及燃料电池汽车产业发展迅速。作为典型的多层、薄壁杯类复杂件，涡旋盘是氢燃料电池系统用涡旋式氢循环泵的核心零件，其性能的优劣对氢燃料电池汽车的氢循系统性能有着极其重要的影响。主要综述了国内外涡旋盘的成形工艺，包括数控铣削、液态压铸、液态模锻、固态热锻、粉末冶金成形等，并分析探讨了不同成形工艺的优缺点;在此基础上，结合笔者的研究经历着重介绍了一种具有“高效短流程”特点的一模四件涡旋盘零件半固态多向挤压成形新工艺，设计了相应的成形模具，并详细介绍了适用于该工艺的模具浇道系统。 |

| Under the background of “carbon peak and carbon neutral”, the hydrogen and fuel cell vehicle industry has developed rapidly in China. As a typical multi-layer and thin-walled cup complex part, scroll is the core part for hydrogen circulating pump used in hydrogen fuel cell system, which has a very important effect on the performance of the hydrogen circulating system of fuel cell vehicle. The current forming processes for scroll at home and abroad were summarized, including numerical control milling, casting, liquid die casting, liquid forging, solid hot forging and powder metallurgy forming. The advantages and disadvantages of different forming processes were analyzed and discussed. Combined with the author’s research experience, a new semi-solid multi-directional extrusion forming process for four scroll parts in one die with the characteristics of “high efficiency and short process” was proposed, and the corresponding forming die was designed. Moreover, the die gate system suitable for the new process was introduced. |
