摘　　要：目的解决15Cr14Co12Mo5Ni钢齿轮锻件易出现粗晶和晶粒度不均匀的问题。方法采用DEFORM数值模拟软件分析15Cr14Co12Mo5Ni钢齿轮成形过程,基于分析结果优化锻件设计方案和锻造工艺方案。结果优化了锻件小端头厚度、中心凹坑尺寸及锻造工艺方案中制坯镦粗高度,使模锻成形过程中齿轮锻件各部位的变形量更加均匀,保证了齿轮小端头难变形区域的变形量≥40%,达到了细化晶粒的目的。结论采用优化后的工艺进行零件试制,结果与DEFORM数值模拟结果相吻合。The work aims to solve the problem of coarse grain and uneven grain size in 15Cr14Co12Mo5Ni steel gear forgings.DEFORM numerical simulation software was used to analyze the forming process of 15Cr14Co12Mo5Ni steel gears.Based on the analysis results,the forging design and forging process scheme were optimized.By optimizing the thickness of the small end of the forging,the size of the center pit,and the upsetting height of the billet in the forging process,the deformation of various parts of the gear forging during forging was more uniform,ensuring that the deformation of the hard to deform area of the small end of the gear was≥40%and achieving the goal of refining the grain size.The optimized process is used for the trial production of the parts,and the results are consistent with the DEFORM numerical simulation results.
