提高多工位M16螺栓冷镦模具寿命的研究

Study on Improving Service Life of Multi- station M16 Bolt Cold Upsetting Die

针对多工位M16冷镦模具生产实际过程中存在寿命低，制造成本高等问题，通过对模具结构、材料及热处理工艺进行优化设计，使模具寿命提高（9—12）倍，增产40％，节约模具用工具钢2kg／万件。

The cold upsetting die for multi -station MI6 Bolt has the problems of the less service life and high cost in the production. Through the optimum design for structure, material and heat - treatment process of the die, the service life of the die increases by （9 -12） times, the production ratio improves by 40% and saves tool steel for die 2kg per ten thousand works.
