Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic induction heating, in particular to a convex welding head. Background Art

[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

[0025] like Figures 1 to 3 As shown, the utility model is a convex welding head, including a body 1. The body 1 adopts an integrated molding structure. The integrated molding structure has high strength and is not easy to be damaged. It can increase the service life of the body 11. At the same time, the integrated molding is easy to manufacture and has a low manufacturing cost. An electromagnetic sheet is installed on the surface of one side of the body 1. A cooling channel 2 is provided in the body 1. The cooling channel 2 is used to pass a cooling medium for cooling. The cooling medium is preferably water, and can also be other media with the same cooling effect. The heat generated when the body 1 is working is cooled by the cooling medium, thereby ensuring that the body is at a lower temperature to avoid damage to it due to excessive temperature, thereby increasing the service life. A water inlet 3 and a water outlet 4 are respectively provided at both ends of the cooling channel 2. The water inlet 3 and the water outlet 4 are respectively arranged at the two ends of the body 1. The cooling medium flows into the cooling channel 2 through the water inlet 3 and is discharged from the water outlet 4.

[0026] By providing a cooling channel 2 in the main body 1, the heat generated by the main body when working is cooled by passing a cooling medium into the cooling channel 2, and by providing a water inlet 3 and a water outlet 4, 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 flow of the cooling medium in the cooling channel 2 forms a cycle, the cooling medium can be continuously passed, and the cooling effect is increased.

[0027] The cooling channel 2 is arranged inside the main body 1 and along the main body 1. The cooling channel 2 has the same shape as the main body 1. The cross-sections of the cooling channel 2 and the main body 1 are both in a "convex" shape. The cooling channel 2 includes a starting section 5, a connecting section 6 and a reflux section 7. The starting section 5 and the reflux section 7 are connected by the connecting section 6. The cooling medium is cooled in turn through the starting section 5, the connecting section 6 and the reflux section 7. The starting section 5 and the connecting section 6 are both stepped. The stepped starting section 5 and the connecting section 6 are used to increase the cooling area of ​​the cooling medium, thereby improving the cooling effect.

[0028] A buffer channel 8 is provided on one side of the reflux section 7 close to the starting section 5 and the connecting section 6. Since the main body 1 has the same structure as the cooling channel 2, a protrusion 13 corresponding to the buffer channel 8 is further provided on the main body 1. Through the setting of the buffer channel 8, the flow rate of the cooling medium is relieved when the cooling medium flows in the reflux section 7. At the same time, due to the design of the protrusion 13, the protrusion 13 cooperates with the main body 1 with a "convex"-shaped structure, thereby increasing the heating area of ​​the main body 1, so that the main body 1 can realize heating and welding of multiple welded parts, thereby improving the welding efficiency to a limited extent, and the overall structure is compact.

[0029] The starting section 5 and the connecting section 6 of the utility model are both stepped, and the stepped starting section 5 and the stepped connecting section 6 are symmetrically arranged. After the starting section 5, the connecting section 6 and the reflux section 7 are connected in sequence, the cross section of the cooling channel 2 presents a "convex" shape, and then a buffer flow channel 8 is provided on one side of the reflux section 7 close to the starting section 5 and the connecting section 6. The buffer flow channel 8 is coordinated with the stepped starting section 5 and the connecting section 6 to increase the cooling area of ​​the cooling medium, thereby improving the cooling effect.

[0030] The corners of the cooling channel 2 are all provided with arc-shaped guide surfaces 9. The design of the arc-shaped guide surfaces 9 allows the cooling medium to flow more smoothly, thereby reducing the impact of the cooling medium on the body 1 and increasing the service life of the body 1.

[0031] A mounting groove 10 is provided on one side surface of the main body 1. The mounting groove 10 is designed along the main body 1 and has the same shape as the main body 1. A positioning hole 11 is also provided in the mounting groove 10. The positioning hole 11 is connected to the cooling channel 2. Through the design of the mounting groove 10 and the positioning hole 11, the electromagnetic sheet is positioned and installed in the mounting groove 10. A positioning piece corresponding to the positioning hole 11 is provided on the electromagnetic sheet. The positioning piece is inserted into the positioning hole 11 to achieve positioning installation. When the electromagnetic sheet is installed, the electromagnetic sheet can be accurately positioned through the cooperation between the positioning hole 11 and the positioning piece, thereby saving installation time, avoiding the movement of the electromagnetic sheet, and preventing the electromagnetic sheet from falling off.

[0032] In this embodiment, when the electromagnetic sheet is installed in the installation groove 10, the electromagnetic sheet and the installation groove 10 can be installed with interference fit by filling the sealing material, and the sealing material can be used to seal to prevent leakage. The electromagnetic sheets can also be welded in the installation groove 10 by welding.

[0033] The edges at the corners of the mounting groove 10 and the body 1 are both configured as arc-shaped transition surfaces 12. The design of the arc-shaped transition surfaces 12 makes the overall appearance more aesthetically pleasing. At the same time, the arc-shaped transition surfaces 12 can also prevent scratches on the operator during daily use and installation of the electromagnetic sheet.

[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.
