It is a technical solution for the best application of this technical solution. The model of the product can be replaced and modified according to the required technical parameters, which is well known to the technical personnel in this field. Therefore, the technical personnel in this field can clearly obtain the corresponding use effect through the technical solution provided by the utility model. Furthermore, the cylinder 8 can be replaced by common automated telescopic equipment such as electric push rods. The output end of the cylinder 8 is rotatably connected to one side of the first connecting block 6. A mounting hole can be opened on one side of the mounting plate 1 for installing a handle or connecting automated equipment (such as a robotic arm, an industrial robot, etc.) for work. The structure is simple and will not be described in detail.

[0031] The first frame 3 and the second frame 4 are both made of metal copper. A through groove is provided on one side of the first frame 3 and the second frame 4. The through groove can prevent the current in the water flow from being opposite to the current on the first frame 3 and the second frame 4, thereby affecting the working effect.

[0032] The first frame 3 and the second frame 4 are both provided with cooling chambers, and one side of the first frame 3 and the second frame 4 is fixedly connected with two copper tubes 9, and the interiors of the copper tubes 9 are connected with the interiors of the corresponding cooling chambers.

The cooling chamber plays a protective role, and the setting of the cooling chamber can also reduce the weight of the device.

[0033] The two rotating blocks 5 are closely fitted to each other at their sides, so that the current can pass through them easily.

[0034] A through hole is provided on one side of the two rotating blocks 5, and bolts are inserted into the two through holes.

For specific connection, see Figure 1 and Figure 2 The induction heating coil is connected to the high-frequency current and cooling water source through the water inlet copper tube 93 and the water outlet copper tube 94. The specific connection is not described in detail due to mature technology. The flow direction of the high-frequency current passes through the water inlet copper tube 93, the second frame 4 on the upper side, the first frame 3 on the upper side, and then enters the second frame 4 and the first frame 3 on the lower side and the water outlet copper tube 94 through the two rotating blocks 5. The output end of the cylinder 8 is extended and the coil is closed. At this time, it is equivalent to a coil wound twice. After it is connected, heating can be carried out.

[0037] An automatic opening induction heating coil, the working principle is as follows:

[0038] 1) When the workpiece needs to be locally heated, the output end of the cylinder 8 contracts to open the coil opening ( Figure 3 As shown, Figure 3 The first hose 91, the second hose 92, the water inlet copper tube 93 and the water outlet copper tube 94 are not shown in the figure), at this time, any position of the workpiece can be put into the heating position from the opening, and then the main controller controls the output end of the cylinder 8 to extend to close the opening, and then a closed loop is formed after the power is turned on to perform heating;

[0039] 2) The induction heating coil is connected to a high-frequency current and a cooling water source through the water inlet copper tube 93 and the water outlet copper tube 94. The high-frequency current flows in sequence through the water inlet copper tube 93, the second frame 4 on the upper side, the first frame 3 on the upper side, and then enters the second frame 4 and the first frame 3 on the lower side and the water outlet copper tube 94 through the two rotating blocks 5. The output end of the cylinder 8 is extended and the coil is closed. At this time, it is equivalent to a coil wound twice, thereby further enhancing the magnetic force in the middle of the induction heating coil to improve the heating efficiency;

[0040] 3) The provision of the through groove can prevent the current in the water flow from being opposite to the current on the first frame 3 and the second frame 4, thereby affecting the working effect.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] The utility model is composed of two groups of first frames 3 and second frames 4 and a cylinder 8. The opening of the induction heating coil can be expanded and closed by controlling the cylinder 8. The structure is very simple and the use is more convenient. The two groups of first frames 3 and second frames 4 can form two coils, which can further improve the heating efficiency of the induction heating coil. The setting of the cooling cavity can cool the first frame 3 and the second frame 4 by water flow to play a protective effect. The setting of the through groove can prevent the current in the water flow from being opposite to the current on the first frame 3 and the second frame 4, thereby preventing the working effect from being affected, thereby ensuring the practicality of the open induction heating coil.
