Abstract：

In order to solve the problem of insufficient electromagnetic flanging angle and low energy utilization rate of electromagnetic flanging for single-tube loaded by traditional single coil, a method of simultaneously loading double-tube electromagnetic flanging with single coil was proposed. Then, the two-dimensional axisymmetric model of electromagnetic flanging was established by simulation software Comsol, and based on the basic principle of tube electromagnetic flanging, the influence of coil height on the forming effect of tube electromagnetic flanging was comparatively analyzed. The simulation results show that when the coil height is 27.4 mm, the flanging angles of the two tubes reach 90°. In addition, compared with the traditional single-tube electromagnetic flanging, because the double-tube electromagnetic flanging can provide a larger and lasting axial electromagnetic force, the flanging effect is significantly improved, and the energy consumption is only 43.83% of that for the single-tube electromagnetic flanging. Obviously, the double-tube electromagnetic flanging method can improve the tube flanging effect and energy utilization rate, which provides an effective and feasible method for the further development of electromagnetic flanging technology.
