[0023] According to the above-described scheme of this utility model, a high-frequency generator 101 is fixedly installed inside the processing rack 1, a transformer 102 is installed at the bottom of the high-frequency generator 101, a high-frequency power supply 103 is installed at the bottom of the transformer 102, a controller 105 is installed on one side of the processing rack 1, and an induction coil 104 is connected to the high-frequency power supply 103. The induction coil is controlled to work by the high-frequency generator, transformer, high-frequency power supply and controller. The workpiece to be heated is placed in the center of the induction coil, and the workpiece is heated by the high-frequency induction principle.

[0024] According to the above-described scheme of this utility model, the sliding screw 202 is located inside the sliding groove 201. The shaft of the first motor 203 is connected to one end of the sliding screw 202. The slider 204 is sleeved on one side of the sliding screw 202. The first motor 203 is bolted to the processing frame 1. The sliding screw 202 is connected to the processing frame 1 by a bearing. The first motor 203 is a geared motor, which facilitates the up-and-down movement of the induction coil 104. The second motor 205 is located inside the sliding groove 201. The second motor 205 is bolted to the slider 204. The shaft of the adjusting disk 206 is connected to one side of the second motor 205. The second motor 205 is a geared motor, which facilitates the rotation of the induction coil 104.

This, in turn, moves the adjusting plate 206 and the induction coil 104 up and down, adjusting the heating height. The second motor 205 drives the adjusting plate 206 to rotate, which in turn drives the induction coil 104 to rotate, adjusting the heating angle and orientation. This allows for easy automatic adjustment of the heating height and angle. After heating is complete, the circulating pump 305 pumps the coolant from the water tank 301 through the pump pipe 302 into the induction coil 104, carrying away the high temperature inside the coil. The coolant then flows back into the water tank 301 through the return pipe 303. The water tank 301 is equipped with an inlet valve and a drain valve, achieving automatic water cooling.
