长期以来 ,我公司圆锥滚子毛坯采用单工位卧式冷镦工艺 ,其特点是效率及自动化程度较高 ,但由于金属只经过一次镦压成型 ,材料变形急剧 ,造成模具寿命低 ,这就要求在设计模具时充分考虑模具的寿命问题。滚子在单击自动冷镦机上镦压成型 ,要经过进料、切断、打入凹模、成型及推 For a long time, our company tapered roller blank used single-station horizontal cold heading process, which is characterized by high efficiency and automation, but because the metal after only a single upsetting, rapid deformation of the material, resulting in low mold life, which Requirements in the design mold fully consider the life of the mold. Roller in the click of the automatic cold heading machine upsetting molding, to go through the feed, cut off, into the die, forming and pushing
