Pipe fitting forming method based on real-time calculation and control of coil assembly energization area

The invention relates to a pipe fitting forming method based on real-time calculation and control of a coil assembly energization area. Each turn of coil of a driving coil assembly is connected with a power source through an independent switch. The conduction state of each turn of coil of the driving coil assembly is independently controlled according to the real-time pipe fitting forming position, namely, the power-on area of the driving coil assembly is adjusted in real time, so that the electromagnetic field direction of the pipe fitting is parallel to the surface of the pipe fitting, and the electromagnetic force borne by the pipe fitting is perpendicular to the surface of the pipe fitting all the time. According to the invention, the flatness of the surface of the metal pipe fitting is improved, that is, the forming quality of the metal pipe fitting is improved, the heat dissipation effect of the coil is improved, and the convenience of overhaul and maintenance of each turn of coil in the driving coil gr
