锤上模锻是目前大批生产模锻件的主要方法之一。由于锤头的行程不固定,能灵活控制轻击、重击等操作,所以工艺的灵活性也较大。可以进行拔长、滚压、弯曲等制坯操作。金属在模膛内的充填性较好,能锻出形状比较复杂的锻件,而且生产率和锻件的精度也较高。但是,和热模锻压力机相比,由于不易实现机械 Hammer on forging is currently a large number of production forging one of the main methods. Due to the hammer’s stroke is not fixed, can flexibly control the tap, swipe and other operations, so the process flexibility is larger. Can be stretched, rolling, bending and other billet operation. Metal filling in the mold cavity is better, can forge a more complex shape forgings, and productivity and forgings of high precision. However, compared with the hot-forging press, it is difficult to implement the machine
