中文摘要：单拐曲轴结构较为复杂，正常情况下应在30 kN模锻锤上锻造。通过对单拐曲轴的结构进行分析，制定出该锻件锻造成型的工艺流程，阐述了模锻工步及其型腔的设计，以及模锻操作方法，实现了在20 kN模锻锤上锻造生产。
英文摘要： The structure of single-throw crankshaft is very complicated. It should be forged in 30 kN forging hammer under normal circumstances. By analyzing the structure of single-throw crankshaft, the process for the forging piece was set down, the working steps, the design of cavity, and the operation of forging die were described. So its production in 20 kN forging hammer was realized.
