Electromagnetic induction heating device

The utility model comprises an openable and closable clamp for clamping the workpiece. The clamp is composed of two semicircular shells made of insulating materials. One end of the two semicircular shells is hinged and the other end is connected through a locking device. The shell is a hollow structure. A plurality of coil units are installed in the shell, and the plurality of coil units are connected in series through wires By adopting the double semicircle opening and closing structure, the utility model is convenient for the coil to be assembled on the axle and other workpieces for heating, which is conducive to reducing the lifting frequency and greatly improving the operation efficiency and safety
