在机械制造行业中,广泛地采用锻造方法锻造长度在500～1000内的圆轴类锻件。所用的设备可在模锻锤、摩擦压力机、热模锻压力机、辊锻机、自由锻锤等设备中选择。在这些设备上进行锻造,取得了一定的效果。目前,长500～1000mm圆轴类锻件常在模锻锤、摩擦压力机或自由锻锤上锻造,但都存在一定的不足。不论是模锻锤上锻造或是在自由锻锤上制坯,然后在摩擦压力机上终锻成形,都因设置毛边槽而耗费原材料。一般毛边损失占零件重量的25％～35％。同时需采用长模具而消耗较多的模具材料,模 In the machinery manufacturing industry, a wide range of forging methods forging the length of 500 to 1000 within the round shaft forgings. Equipment used in die forging hammer, friction presses, hot forging presses, roll forging machines, free forging hammer and other equipment to choose from. Forging on these devices, and achieved some results. At present, the long 500 ~ 1000mm round shaft forgings often die forging hammer, friction press or free forging hammer forging, but there are some shortcomings. Whether forging hammer forging or forging hammer on the free billet, and then forged on the friction press forging, because of burrs and set the raw material costs. The gross burr loss accounts for 25% ~ 35% of the weight of the part. At the same time need to use a long mold and consume more mold material, mold
