摘要
为克服传统单一径向电磁力翻边过程中翻边角度难以达到90°的缺陷,该文提出一种基于轴-径双向电磁力加载模式的电磁翻边系统来改善管件的翻边效果。仿真数据表明,与仅有径向线圈的电磁翻边系统相比,双向电磁力翻边系统中引入的强轴向电磁力在很大程度上增强了材料的轴向流动,进而提升了翻边角。此外,基于特定的铝管(AA6061-O)进行了对比实验,验证了该电磁翻边方法的有效性。实验结果表明,相同条件下基于双向电磁力加载管件电磁翻边方法的翻边角度是传统单线圈翻边模式下的3倍。显然,电磁力施加方式的改进能有效地解决管件电磁翻边存在的问题,促进电磁成形技术在工业上的广泛应用。
The flanging angle is difficult to reach 90°in the process of conventional single radial electromagnetic force flanging.Thus,an electromagnetic flanging system based on axial-radial bidirectional electromagnetic force loading mode is proposed to improve the flanging effect of pipe fittings.The simulation data show that compared with the electromagnetic flanging system with only radial coils,the strong axial electromagnetic force introduced by the bi-directional electromagnetic flanging system significantly enhances the axial flow of the material,and then improves the flanging angle.In addition,comparative experiments based on a specific aluminum tube(AA6061-O)verify the effectiveness of the new electromagnetic flanging method.The experimental results demonstrate that the flanging angle of the tube electromagnetic flanging method based on bidirectional electromagnetic force loading is three times that of the traditional single coil flanging mode.Obviously,the improvement of electromagnetic force applying mode can effectively tackle the problems existing in tube electromagnetic flanging and promote the comprehensive application of electromagnetic forming technology in industry.
