摘　　要：归纳并分析了内花键齿形成形工艺方式,运用DEFORM-3D有限元软件,采用直接成形、间接成形两种方式对其冷挤压过程进行了模拟。结果表明:增加一道预成形工序来间接成形内花键齿形能够大大提高生产效率、端面尺寸精度及模具使用寿命,最优成形孔尺寸为20.5mm。After summarizing and analyzing the forming technology of internal spline tooth, the cold extrusion processes were simulated with FE software DEFORM-3D by direct forming and indirect forming. The results show that： indirect forming adding a prefomaing process can mostly improve the production efficiency, the dimension accuracy of the end surface and the die working life. The optimal forming hole size is 20.5 mm.
