剥皮齿作为木材剥皮机的刀具，其在高强度作业下，要求硬度高、耐腐蚀性强。提出了采用锻造成形方式加工剥皮齿，并基于Deform-3D模拟软件分析了剥皮齿热锻工艺参数对锻造成形质量的影响，揭露了剥皮齿热锻过程的成形规律，验证了设备选型、锻造方案及模具设计的合理性。通过正交试验对热锻过程中的工艺参数设置进行优化，最终制定了坯料温度为1180 ℃、预锻上下模间距为3.0 mm、终锻上下模间距为3.3 mm、上模运动速度为500 mm·s-1、摩擦因数为0.25的优化工艺参数组合。采用优化后的工艺参数组合方案，上模载荷相对于优化前降低了4.48%，提高了锻件的内部质量与模具的使用寿命。

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.
