摘　　要：为了减少铡草机刀片的磨刀频率,对铡草机刀片采用局部气体渗碳和淬火回火工艺进行强化,使其表面硬、心部韧。试验证明:工作时间内刀片保持了良好的自磨刃效果,磨刀频率明显降低,从而提高了刀片的使用寿命以及铡草机的加工质量和加工效率。In order to reduce the frequency of nail cutting,the chaff cutter bladders were strength by using a local gas local gas carburizing,quenching and tempering process,which is to form a blade with difference hardness.Good self-sharpening effects were maintain in the chaff cutter's effective working hour,sharpening frequency was significantly reduced,thereby,the life of the blades chaff cutter,processing quality and processing efficiency was increased.
