凸轮轴高紧凑锻模优化设计与应用

Optimization Design and Application of Camshaft High Compact Forging Die

以凸轮轴锻模设计与应用为研究对象,设计了在1副锻模中锻造成形2种进气、排气凸轮轴的高紧凑锻模,改变了原进气、排气凸轮轴需要设计和制造2副独立锻模的不利因素,扩大了锻模使用功能,降低了锻模制造与使用成本(降低锻模制造费50%),提高了锻造效率(减少锻模安装次数1次),提高了锻模使用寿命高(由原使用寿命5,000件/副提高到7,000件/副),提高了锻件合格品率(由原合格品率不足95%提高到现在的98%以上)。

The study types air inflow, air out disadvantage factors of take the camshaft forging die as the research object, camshaft high compact forging die in a set of forging d have designed two to overcome the manufacture two set of different forging die, expand the using function of forging die, reduce the forging die manufacture and use cost （reduce the forging die manufacturing cost by 50%）, increase the forging efficiency （Reduce the frequency installation）, increases the service life of forging die（the original 5,000 / pair service life have increased up to 7,000/pair）, increase the rate of qualified products of forge piece （the qualification rate were less than 95% have increased more than 98% now）.
