【摘要】 前轴是汽车中的大型重要锻件,其生产工艺可归纳为锤上模锻、热模锻压力机上模锻、成形辊锻、精辊-模锻复合工艺等几种类型。其中,前两种以模锻成形为主,需要较大吨位的锻造设备;后两种以辊锻成形为主,所需锻造设备的吨位较小。生产实践表明,成形辊锻和精辊-模锻工艺可大幅度地节省设备投资,降低生产成本。更多还原

【Abstract】 Front axle is one of heavy forgings for automobiles.The production process includes hammer die forging,pressure forging,roll forging forming,and precision rolling-die forging composite technology.The two former processes belong to die forging forming where larger tonnage of forging equipment is required,while the two latter processes belong to roll forging forming where smaller tonnage of forging equipment is required.Practical production showed that roll forging forming technology and precision rolling-die forging composite technology can remarkably save equipment investment and reduce costs.更多还原
