摘要
介绍直齿圆柱齿轮冷挤压精密成形的试验过程，探索正挤齿轮与分流终压一次成形的最佳工艺方案。结果表明，约束分流在改善充填性等方面具有较多优点，为生产实用化提供了可行性依据。
The experimental procession of precise cold-extrusion of spur gear is described in this paper, and the optimal processing method for the extrusion of gear and the ultimate extrusion by dividing metal flow is also discussed here .The experimental result shows that the restrained divided flow has a lot of merits with regard to improving metal's ability to fill out the mould, and it provides a reliable basis for practical use.
