Abstract：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.
