现时,每年需生产50万根以上的车轴,以满足车辆制造和修理之用。生产可变直径的车轴,金属用量很大,劳动条件也很繁重。在锻锤或压力机上自由锻造或模锻生产车轴,生产率低,金属损失势必很大,劳动条件繁重。这种情况以及对车轴的需求日益增长,不得不寻求新的车轴制造方法。新方法有螺旋轧制、径向锻造机 At present, it is necessary to produce more than 500,000 axles a year to meet the needs of vehicle manufacturing and repair. Production of variable diameter axles, a large amount of metal, working conditions are also very heavy. Free forging or die forging production of axles on forging hammers or presses, low productivity, large metal losses, heavy labor conditions. This situation and the increasing demand for axles have forced the search for new ways of making axles. New methods are spiral rolling, radial forging machine
