| 中文摘要: |
| 以16V280曲轴为试验对象，通过对RR装置的镦锻工艺、曲柄臂锻件形状和锻造模具结构优化，研究了采用小直径坯料的情况下16V280曲轴曲柄臂的成形情况。试验结果显示，优化后的预上弯镦锻工艺，能保证在RR装置上采用小直径坯料镦锻曲轴可行。 |
| 英文摘要: |
| The 16V280 crankshaft has been investigated as an object of study. Through the optimization of forging process on RR device, forging shape of crank web and structure design of forging die, deformation test has been done to study the forming status of crank web in the case of adopting blank in smaller diameter. Testing result shows that it's available that adopting blank of smaller diameter to forge crankshaft on RR device by the means of upward pre-forging. |
