摘要: 为了优化滚珠丝杠的感应加热工艺,提高其表面温度分布的均匀性,从而提升其制造精度与性能,通过电磁仿真软件构建有限元模型,分析了静态和动态感应加热过程中不同工艺参数对丝杠表面温度场分布的影响。结果表明,感应线圈内径过小,工件与线圈间隙狭窄,容易导致工件表面过热或过烧,内径过大则间隙过宽,导致加热效率降低并使加热层深度变浅,选择内径合适的感应线圈对于确保加热质量至关重要;双匝线圈在加热效率和温度均匀性上表现最佳;高电压和适宜电流频率可提高加热效率并控制加热层深度;动态加热中,推荐扫描速度为6~10 mm/s,以平衡加热效率和工艺稳定性。

Abstract: In order to optimize the induction heating process of ball screw and improve the uniformity of its surface temperature distribution, thereby improving its manufacturing precision and performance, a finite element model was constructed by means of electromagnetic simulation software to analyze the influence of different process parameters on the surface temperature distribution of the ball screw during both static and dynamic induction heating. The results show that an excessively small internal diameter of the induction coil results in a narrow gap between the workpiece and the coil, which can easily lead to overheating of the workpiece surface. Conversely, an excessively large internal diameter results in a wide gap, reducing heating efficiency and resulting in a shallow heating layer. Therefore, selecting an induction coil with an appropriate internal diameter is essential for ensuring the quality of heating. The double-turn coil demonstrates superior performance in terms of heating efficiency and temperature uniformity. Employing high voltage and an appropriate current frequency can improve heating efficiency and control the depth of heating layer. For dynamic heating, a scanning speed of 6-10 mm/s is recommended to achieve a balance between heating efficiency and process stability.
