Abstract：

As the cutting tool of wood peeling machine, the peeling tooth requires high hardness and strong corrosion resistance under high-intensity operation. Therefore, the forging method was proposed to process peeling tooth, and the influences of hot forging process parameters on the forging quality of peeling tooth were analyzed based on simulation software Deform-3D. Then, the forming rules of hot forging process for peeling tooth were revealed, and the rationality of equipment selection, forging scheme and mold design was verified. Furthermore, the setting of process parameters in the hot forging process was optimized by the orthogonal test, and the optimal combination of process parameters with the blank temperature of 1180 ℃, the upper and lower mold clearance in pre-forging of 3.0 mm, the upper and lower mold clearance in final forging of 3.3 mm, the upper mold movement speed of 500 mm·s-1 and the friction coefficient of 0.25 was formulated. Finally, by using the optimal combination scheme of process parameters, the upper die load was reduced by 4.48% compared to that before optimization, and the internal quality of forgings and the service life of mold were improved.
