Abstract

The electromagnetic tube compression is a high-speed electromagnetic pulse-forming process. The process can be used for connecting metal tube with other tube and bar, and the traditional forming method can be partially replaced. At present, the development and application of the electromagnetic forming technology are restricted, and the main problems are the control of the forming process, the precise forming, and accurate measurement of small diameter tubes. Through the electromagnetic tube compression experiment and optical strain measurement of 6063 aluminum alloy, small diameter tubes were carried out; the numerical simulation analysis of electromagnetic field under different field shaper parameters was carried out and combined with theoretical derivation. In this paper, the theoretical relationship between the electromagnetic force and the process parameters was determined, the influence of the discharge voltage and the process parameters of the field shaper on forming was analyzed, and the reasons for the difficult forming of the small diameter tubes were discussed. The result shows that, the smaller the tube diameter, the harder it is to form. The greater the angle of inner slope of the field shaper, the higher the forming efficiency, and the angle is 40°, which is more reasonable. The higher the discharge voltage, the greater the deformation. The combination of traditional measurement and optical measurement is efficient and accurate to measure tube strain. The uneven distribution of the electromagnetic force along the circumferential direction is caused by the gap of field shaper, which is the main reason for the uneven deformation of the aluminum tube.
