This paper presents the experiment and investigation of automotive engine crankshafts made of 45V untempered steel. The heated temperature, the final forging temperature and the cooling speed are the important factors which influence the performance of untempered steel. After forging and cooling in ter air, the precipitation hardened 45V untempered steel can obtain the same fatique strength as the 45 tempered one. The 45V steel crankshafts have small deformation in production and need not a straightening operation....

This paper presents the experiment and investigation of automotive engine crankshafts made of 45V untempered steel. The heated temperature, the final forging temperature and the cooling speed are the important factors which influence the performance of untempered steel. After forging and cooling in ter air, the precipitation hardened 45V untempered steel can obtain the same fatique strength as the 45 tempered one. The 45V steel crankshafts have small deformation in production and need not a straightening operation. The 45V steel crankshafts have a better cutting property than 45 tempered ones. However, the 45V steel has lower toughness and plasticity than 45 tempered one. It is necessary to do more road test under Low temperature.

本文介绍了用45V非调质钢制造发动机曲轴的试验研究。锻造加热温度、终锻温度和冷却速度是影响非调质钢性能的重要因素。锻后空冷析出强化的45V钢的疲劳强度与45钢基本相同。45V钢曲轴变形较小,可以取消锻后冷校直工序。45V钢曲轴的切削略优于45钢。45V钢的韧性和塑性低于45钢,应对45V钢曲轴低温使用性能进一步考核。

In this paper, the novel structure and characteristics of a movable doubleploner type hydraulic straightening machine are introduced. The machine is used forcool straightening the welded spares of bogie and its hydraulic system is brieflymustrated.
