摘　　要：采用温挤压工艺成形凿岩机钎套,用Deform-3D软件对温挤压成形过程进行数值模拟,分析了不同工艺参数对凿岩机钎套温挤压成形的影响。结果表明,当摩擦系数为0.15、毛坯温度为650℃、挤压速度为10mm·s^(-1)时,可获得的挤压件的效果最为理想,为此类零件的实际生产提供有价值的工艺参数参考。This paper adopted warm extruding process for forming brazing sets of rock drill. Deform-3D software is used on numerical simulation of warm extruding process, the influence of different process parameters on warm extruding is analyzed. The results showed that the good quality of formed parts can be obtained with friction coefficient of 0.15, warm extruding temperature of 650℃, warm extrusion speed of 10mm. s-1, to provide a reference for the practical production of such parts.
