摘　　要：为了提高铡草机刀片强度、硬度和耐磨性,对刀片进行单面渗碳和热处理,以达到自磨刃强化目的,但热处理过程中淬火回火后刀片发生了变形。为此,以碳素结构钢Q235为研究材料,选用不同淬火回火工艺参数进行处理,分析比较刀片自磨刃强化处理过程中刀片的变形规律。in order to improve the hay cutter blade strength, hardness and wear resistance, the blade for single carburi- zing and heat treatment in order to achieve self grinding blade strengthen purpose, but in the process of heat treatment quenching after tempering blade happened deformation. Based on carbon structural steel Q235 as the research material, choose different quenching tempering process parameters processing, analysis and comparison blade from grinding blade reinforcement in the course of processing, the deformation law of the blade.
