摘要：

针对传统线圈管件电磁翻边能量利用率低和轴向电磁力较小等问题，提出一种基于T型线圈的双管件电磁翻边方法。利用Comsol软件建立了基于传统线圈管件、凸型线圈管件以及T型线圈双管件电磁翻边3组对比模型，分析了管件翻边区域的磁通密度分布、电磁力分布以及塑性应变能和能量利用率，并进一步研究了相同翻边角度下T型线圈提高的能量利用率。结果表明：在相同的放电电压下，T型线圈双管件电磁翻边的塑性应变能最大，能量利用率大幅提升，较传统线圈和凸型线圈管件电磁翻边分别提升了69.75%和31.89%；在3组模型均达到最佳翻边效果（翻边角度为90°）时，T型线圈双管件翻边模型所需的放电能量最少，仅为1.39 kJ，且相较传统线圈和凸型线圈管件电磁翻边，能量利用率分别提升了49.82%和37.67%。基于T型线圈的双管件电磁翻边技术解决了电磁翻边能量利用率低的问题，为电磁翻边的工业应用提供了新的研究思路。

For the problems of low energy utilization rate and weak axial electromagnetic force in the traditional coil tube fittings electromagnetic flanging process, a dual tube fittings electromagnetic flanging method based on T-coil was proposed, and three comparison models of electromagnetic flanging based on traditional coil tube fittings, convex coil tube fittings and T-coil dual tube fittings were established by using software Comsol. Then, the magnetic flux density distribution, electromagnetic force distribution, plastic strain energy and energy utilization rate in the flanging area of the tube fittings were analyzed, and the improved energy utilization rate of T-coil under the same flanging angle was further studied. The results show that under the same discharge voltage, the plastic strain energy of T-coil dual tube fittings electromagnetic flanging is the highest, and the energy utilization rate is greatly improved. Compared with traditional coil and convex coil tube fittings electromagnetic flanging, the energy utilization rate is improved by 69.75% and 31.89%, respectively. When all tube fittings of three models achieve the best flanging effect (flanging angle of 90°),the flanging model of T-coil dual tube fittings requires the least discharge energy, only 1.39 kJ, and compared with the traditional coil and convex coil tube fittings electromagnetic flanging, the energy utilization rate is increased by 49.82% and 37.67%, respectively. The T-coil dual tube fittings electromagnetic flanging technology solves the problem of low energy utilization rate, providing new research ideas for the industrial applications of electromagnetic flanging.
