摘　　要：通过有限元软件Ansys Maxwell,建立了感应线圈与感应淬火工件之间的电磁场-温度场耦合数学模型,得到感应加热过程中的磁场分布与工件温度场分布,并通过感应淬火试验对模拟结果进行了验证。结果表明,所设计的感应线圈可使磁场聚集在工件淬火区域表面,实现感应加热,且3匝线圈加热10 s效果最优,工件表层最高温度约为903℃,达到设计预期。感应淬火试验结果与模拟结果吻合较好,丝杠坯料的硬化层深度为4.6 mm,硬度分布为半马鞍形,表面硬度明显提升,达到61.5 HRC,达到工艺要求。表明感应线圈设计合理,感应淬火工艺适当,可应用于高精度保持性滚珠丝杠坯料的生产。Electromagnetic field-temperature field coupling mathematical model between the induction coil and the induction quenching workpiece was established by using the finite element software Ansys Maxwell.The magnetic field distribution and the temperature field distribution of the workpiece during the induction heating process were obtained,and the simulation results were verified by the induction quenching test.The results show that the induction coil can make the magnetic field gather on the surface of the quenching area of the workpiece to realize induction heating.The effect of induction heating with 3 turns coil for 10 s is the best,and the maximum temperature of the workpiece surface is about 903℃,which meets the design expectation.The induction quenching test results are in good agreement with the simulation results.The hardened layer depth of the screw blank is 4.6 mm,the hardness distribution is semi-saddle-shaped,and the surface hardness is significantly improved to 61.5 HRC,which meets the process requirements,indicating that the induction coil design is reasonable and the induction quenching process is appropriate.It can be applied to the production of high-precision retention ball screw blanks.
