载重汽车的主要承载零件前轴是个重型弯曲类模锻件,其形状复杂,基本上不机加工,且技术要求较高.如解放汽车前轴(见图1),重量为58kg,材料为45钢,按锻件要求在小于5t模锻锤上是很难锻成的,一汽是在5t模锻锤上分两段调头锻成的,山西某专业锻造厂则是在16t模锻锤上整体锻成的,东风汽车前轴则是在前轴自动生产线上经12000kN热模锻压力机整体成形的.我厂虽尚无此条件,但经过试验后,在750kg空气锤及1t锤上也成功、成批地锻出延安汽车前轴.
The main load-bearing parts of the truck front axle is a heavy-duty curved die forgings, its shape is complex, basically not machined, and high technical requirements, such as the liberation of the front axle (see Figure 1), weighs 58kg, the material is 45 steel , According to the requirements of forgings in less than 5t die forging hammer is hard to forge, FAW is 5t die forging hammer in two sections forging, Shanxi is a professional forging plant is forged in the overall 16t forging hammer , The front axle of Dongfeng Motor is integrally formed by the 12000kN hot-die forging press in the automatic production line of the front axle, though our factory does not have such conditions yet, after the test, it succeeded in 750kg air hammer and 1t hammer as well Lot forging out of Yanan car front axle.
