In order to realize the controllable loading of electromagnetic force in electromagnetic forming and improve the forming effect of tube, this paper puts forward an electromagnetic forming technology of tube based on double magnetic field converters. In this technology, two magnetic field converters are introduced between the tube and the driving coil, and the electromagnetic force is regulated by changing the geometric parameters and spacing of the magnetic field converters. Based on the specific 2024- aluminum alloy tube, the simulation research is carried out. The simulation data show that the change of the geometric structure and spacing of the two magnetic field converters can change the induced eddy current and realize the regulation of electromagnetic force. Compared with the traditional electromagnetic forming of tube, the uniform forming range Dr of electromagnetic forming of Dr based on double magnetic field converters is increased by 2.77 times. To sum up, the electromagnetic forming technology based on double magnetic field converters can effectively improve the forming uniformity of tube and promote the wide application of electromagnetic forming technology in industry.
