摘要
对凿岩机异形内齿套筒的冷挤压整体成形进行了试验研究。结果表明：用径向挤压代替反挤压内齿，能降低挤压力、利于提高模具使用寿命、产品质量，能满足设计要求。
The cold extrusion of sleeve with special shaped interal gear is experimentally researched.The backward extrusion is substituted by radial extrusion. The results shown that the extruded force is decreased and the die life is increased.The quality of the sleeve which is used in rock drill can meet the needs of design.
