摘要: 针对滚珠丝杠感应加热过程中齿顶与凹槽温度分布不均的问题,提出一种渐进式双频感应加热工艺优化方法。通过构建多物理场耦合有限元模型,系统地研究了双频协同加热模式下,电流频率、电压和线圈扫描速度等参数配比对温度场均匀性的影响规律。结果表明,采用低频(500 Hz/75 V)预热与中频(2000 Hz/70 V)二次加热的协同模式,结合12 mm/s等速扫描工艺,能够使齿顶与凹槽温差控制在26 ℃以内,同时使齿顶与凹槽有效加热层深度分别满足5~8 mm和3~4 mm的技术要求。相较于常规单频工艺,该方法可显著改善齿顶与凹槽温度分布不均的问题,与仿形感应加热工艺水平相当。

Abstract: Aiming at the non-uniform temperature distribution between the tooth crest and groove of ball screw during induction heating, a progressive dual-frequency induction heating process optimization method was proposed. A multi-physics coupled finite element model was established to systematically investigate the influence of parameter combinations (current frequency, voltage, and coil scanning speed) on temperature field uniformity under dual-frequency cooperative heating. The results demonstrate that the synergistic mode combining low frequency preheating (500 Hz/75 V) and medium frequency secondary heating (2000 Hz/70 V), coupled with a constant scanning speed of 12 mm/s, effectively controls the temperature difference between the tooth crest and groove within 26 ℃. Simultaneously, the effective heating layer depths of the tooth crest and groove meet the technical requirements of 5-8 mm and 3-4 mm, respectively. Compared with conventional single-frequency processes, this method significantly improves the non-uniform temperature distribution between the tooth crest and groove, achieving performance levels comparable to profiling induction heating process.
