Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a welding head of a high-frequency welding machine. Background Art

[0002] The high-frequency welding machine performs high-frequency welding on components through the welding head. Its working principle is to use the skin effect of high-frequency current to concentrate the high-frequency electrical energy on the surface of the weldment, and use the proximity effect to control the position and range of the high-frequency current flow path. By using the skin effect and proximity effect, the surface metal of the weldment to be welded can be quickly heated to achieve welding. However, since a large amount of heat is generated when the welding head is working, the welding head needs to be cooled to prevent long-term high temperature from damaging the welding head. However, the cooling effect of the welding head in the prior art is not good, which affects the service life of the welding head. Utility Model Content

[0028] like Figures 1 to 5 As shown, the welding head of the high-frequency welding machine of the utility model is mainly used to set a cooling channel 21 in the main body 10, and the cooling channel 21 is used to pass a cooling medium for cooling. A water inlet 12 and a water outlet 13 are respectively provided at both ends of the cooling channel 21. The cooling medium flows into the cooling channel 21 through the water inlet 12 and is discharged from the water outlet 13, so that the cooling medium forms a circulation in the cooling channel, and the cooling medium can be continuously passed to increase the cooling effect.

[0029] The utility model high frequency welding machine welding head comprises an integrally formed body 10, a mounting groove 11 is provided on the surface of the body 10, the mounting groove 11 is used to install an electromagnetic sheet, the shape of the mounting groove 11 is set according to the shape of the electromagnetic sheet, a cooling channel 21 for medium circulation is provided in the body 10, a water inlet 12 and a water outlet 13 are provided at both ends of the cooling channel 21, and the water inlet 12 and the water outlet 13 are communicated with the cooling channel.

[0030] The main body 10 is specifically arranged in an eight-shaped ring shape, and a partition groove 14 and a through groove 19 are penetrated by the main body 10. The partition groove 14 is communicated with the through groove 19. The cooling channel 21 is divided into a water inlet section 15, a connecting section 16 and a water outlet section 17 through the partition groove 14 and the through groove 19. The connecting section 16 connects the water inlet section 15 and the water outlet section 17.
