[0002] High-frequency welding machine is a welding device used for various metal materials. The working principle of high-frequency welding machine is to use the principle of electromagnetic induction to convert into a high-frequency magnetic field and act on the metal object in the magnetic field; using the eddy current effect, an induced current proportional to the magnetic field strength is generated in the metal object. This eddy current is affected by the skin effect. The higher the frequency, the more concentrated it is on the surface of the metal object. When the eddy current flows in the metal object, it will generate heat by using the principle of current thermal effect with the help of the inherent resistance value inside. This heat is generated directly inside the object. Therefore, the heating speed is fast and the efficiency is high. It can melt any metal object instantly. Moreover, the heating speed and temperature are controllable. The welding head used in the existing high-frequency welding machine will generate a lot of heat when working. In order to prevent the high temperature from damaging the welding head after long-term use, it needs to be cooled. Therefore, how to cool the welding head is a problem that technicians in this field need to solve urgently. Utility Model Content

DETAILED DESCRIPTION

[0026] like Figures 1 to 4 As shown, the welding head of the utility model for a high-frequency welding machine includes a body 1 and an electromagnetic sheet. A mounting groove 15 is provided on one side surface of the body 1. The mounting groove 15 is used to install the electromagnetic sheet. The mounting groove 15 facilitates the installation of the electromagnetic sheet. The electromagnetic sheet can be installed in the mounting groove 15 by welding or by filling the mounting groove 15 with sealing material.

[0027] The body 1 includes a first ring portion 12, a second ring portion 13 and a connecting portion 14. The connecting portion 14 is disposed between the first ring portion 12 and the second ring portion 13. The first ring portion 12 and the second ring portion 13 are connected by the connecting portion 14, so that the body 1 is in an "S" shape as a whole. Both ends of the "S"-shaped body 1, namely, the end of the first ring portion 12 and the end of the second ring portion 13 are provided with arc transition surfaces 16. The design of the arc transition surface 16 reduces the concentration of stress and increases the service life of the body 1. At the same time, the arc transition surface 16 can avoid scratches and increase the safety of use. In this embodiment, the first ring portion 12, the second ring portion 13 and the connecting portion 14 are in an integrated structure. The integrated overall structure has high strength and can increase the service life of the induction coil. At the same time, the integrated structure is easy to manufacture and reduces the manufacturing cost.

[0028] A cooling channel 2 is provided in the body 1. The cooling channel 2 is arranged along the body 1, that is, the cooling channel 2 as a whole is also in an "S" shape. The cooling channel 2 is used to pass a cooling medium for cooling. The cooling medium can be water or other media with the same effect. A water inlet 3 and a water outlet 4 are respectively provided at both ends of the cooling channel 2. The water inlet 3 is opened on the first ring portion 12, and the water outlet 4 is opened on the second ring portion 13. The cooling medium flows into the cooling channel 2 through the water inlet 3 and is discharged from the water outlet 4.

[0029] The utility model provides a cooling channel 2 in a main body 1, cools by passing a cooling medium into the cooling channel 2, and provides a water inlet 3 and a water outlet 4, so that the cooling medium flows into the cooling channel 2 from the water inlet 3 and is discharged through the water outlet 4 after cooling, so that the cooling channel 2 forms a circulation, the cooling medium can be continuously passed, and the cooling effect is increased.

[0030] The cooling channel 2 includes an inlet channel 5, a buffer channel 6 and an outlet channel 7. The inlet channel 5 is connected to the water inlet 3, and the outlet channel 7 is connected to the water outlet 4. The inlet channel 5 and the outlet channel 7 are connected through the buffer channel 6. The flow rate of the cooling medium is buffered by the buffer channel 6 to reduce the impact of the cooling medium on the cooling channel 2 and increase the service life of the main body 1. The buffer channel 6 includes a buffer surface 8 and a guide surface 9. The buffer surface 8 is connected to the inlet channel 5, and the guide surface 9 is connected to the outlet channel 7. The buffer surface 8 and the guide surface 9 are both arc-shaped. The arc-shaped buffer surface 8 and the arc-shaped guide surface 9 are arranged opposite to each other, so that the formed buffer channel 6 is wavy. When the cooling medium flows from the inlet channel 5 to the outlet channel 7, the cooling medium is first slowed down by the buffer surface 8 to reduce the impact of the cooling medium on the cooling channel 2, thereby avoiding damage to the main body 1 and extending the service life of the main body 1. Then, the flow direction is changed by the guide surface 9 to facilitate the cooling medium to flow into the outlet channel 7.

[0031] In this embodiment, the water inlet channel 5 is further provided with a first arc-shaped guide surface 10, and the water outlet channel 7 is further provided with a second arc-shaped guide surface 11. The cooling medium is guided by the first guide surface 10 and the second guide surface 11, so that the cooling medium can flow more smoothly, reducing the impact of the cooling medium on the main body 1 and increasing the service life of the main body 1.

[0032] The flow process of the cooling medium in the utility model is:

[0033] The cooling medium first enters the water inlet channel 5 through the water inlet 3, and is guided by the first guide surface 10 of the water inlet channel 5, and is guided into the buffer channel 6. In the buffer channel 6, the cooling medium is first cooled by the buffer surface 8, and then guided into the water outlet channel 7 by the guide surface 9, and is guided by the second guide surface 11 of the water outlet channel 7, and finally discharged from the water outlet 4. This process is repeated continuously. When the cooling medium flows in the cooling channel 2, it exchanges heat with the heat generated by the induction coil when it works, thereby taking away the heat inside the main body 1, thereby ensuring that the temperature of the main body 1 is at a relatively low level, thereby increasing the cooling effect.

[0034] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
