曲轴先进锻造技术的研究与应用

Study and application of advanced crankshaft forging technology

通过对曲轴锻件产品的结构特点和锻造工艺分析,提出了今后曲轴的生产将更多的采用大型自动化生产线,模锻锤生产工艺将逐渐被淘汰。随着国家节能改造技术的推广应用,曲轴锻造用钢材将由调质钢向微合金结构钢转化,同时,一些新的技术、新工艺也将更多的应用于曲轴锻件的生产,将极大的促进我国曲轴锻件市场的发展和国际竞争力。

Through the structure characteristic and forging process analysis of the crankshaft products,more full automatic production lines will be adopted in the production of crankshaft in the future,and the forging hammer production technology of the mould will be eliminated.With the popularization and application of country＇s reducing energy consumption technology,the steel of forged crankshaft transforms from quenched steel to the little structural alloy steel,meanwhile,some new technologies and processes will be applied in production of crankshaft which greatly improve the development and international competitiveness of inland crankshaft market.
