Abstract：

According to the structure characteristic of the outer tooth of reverse gear, two cold precision forging processes were determined. The above two processes were numerically simulated by finite element software Deform-3D, and the metal flow rate and filling effect of the two different forming processes were compared. The results show that when the outer tooth of reverse gear is produced by cold extrusion-cutting technology, the metal flow is uniform with a desirable filling effect. Furthermore, products are filled completely at the bottom corner of the boss, and the whole gear and tooth surface are obtained. Finally, both the forming precision and anti-fatigue strength of the outer tooth are improved.
