一、锻造在轴承生产中的地位和作用 在一套轴承中,套圈的重量平均约占整套轴承重量的70％,成本约占50～70％。大多数轴承套圈都是通过锻造加工来获得毛坯的。因此,在轴承制造厂,锻造加工是生产轴承必不可少的基本加工环节之一,是套圈加工的第一道工序。 采用锻造加工,有利于提高钢材利用率,减少车加工工时,降低生产成本。以加工203轴承内圈
First, the role of forging in the production of bearings In a set of bearings, the weight of the ferrule on average about 70% of the entire bearing weight, the cost of about 50 to 70%. Most bearing rings are obtained by forging rough. Therefore, in the bearing factory, forging process is one of the basic production processes necessary for the production of bearings, ferrule processing is the first process. Forging processing, is conducive to improving the utilization of steel, reduce vehicle working hours and reduce production costs. To process 203 bearing inner ring
