开缝衬套冷挤压孔工艺

The Process of Cold Worked Hole With Split-Sleeve

对开缝衬套冷挤压孔和芯棒直接冷挤压孔的工艺方法进行了比较 ,并对开缝衬套冷挤压孔工艺参数、孔挤压后铰削量与疲劳寿命的关系以及孔挤压后残余压应力释放进行了研究。

The difference between the cold worked hole with and without split _sleeve is compared . The process parameters of the cold worked with splitsleeve, the relationship of the amount of material removed by reaming and the fatigue life as well as the release of compressive residual stress after coldworking are studied.
