Description

Technical Field

[0001] The utility model relates to the technical field of welding heads, in particular to a welding head with a water cooling effect. 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 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 the 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. In particular, when welding multiple tubes or special-shaped tubes through the welding head, it is necessary to ensure good cooling effect and stability to achieve high-frequency welding between pipes. 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

[0003] The utility model provides a welding head with a water cooling effect, which solves the problems of poor cooling effect and short service life of the welding head in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] Welding head with water cooling, including

[0006] ontology;

[0007] The invention is characterized in that: a cooling channel is provided in the body, the cooling channel is used to pass cooling medium for cooling, a water inlet and a water outlet are respectively provided at both ends of the cooling channel, the cooling medium flows into the cooling channel through the water inlet and is discharged from the water outlet, so that the cooling medium forms a circulation in the cooling channel, the cooling medium can be continuously passed, and the cooling effect is increased.

[0008] Furthermore, the cooling channel includes a water inlet channel, a buffer channel, a connecting channel, a torrent channel and a water outlet channel. The water inlet channel is connected to the buffer channel through the torrent channel, and the water outlet channel is connected to the buffer channel through the connecting channel. The medium passes through the water inlet channel, the torrent channel, the connecting channel, the buffer channel and the water outlet channel in sequence to complete the cooling of the body. The main process is that the cooling medium first enters the welding head through the water inlet channel, then increases its speed and pressure through the torrent channel, and then exchanges heat with the inside of the welding head through the connecting channel and the buffer channel, and finally is discharged from the welding head through the water outlet channel. This cycle is repeated continuously, thereby continuously taking away the heat inside the welding head, keeping the temperature of the welding head at a relatively low level, and improving the cooling effect.

[0009] Furthermore, a mounting groove is provided on the surface of the main body, and the mounting groove is used to install the electromagnetic sheet, so as to facilitate the positioning and installation of the electromagnetic sheet.

[0010] Furthermore, a positioning hole communicated with the cooling channel is provided in the mounting groove, and the positioning hole is used to position the electromagnetic sheet. The setting of the positioning hole enables the electromagnetic sheet to be firmly installed in the mounting groove without falling off. At the same time, a positioning portion corresponding to the positioning hole is provided on the electromagnetic sheet to facilitate the positioning and installation of the electromagnetic sheet and prevent the electromagnetic sheet from being displaced.

[0011] Furthermore, the edges in the installation groove are all set as arc transition surfaces. The setting of the arc transition surface can reduce stress concentration and increase the service life of the welding head. At the same time, the arc transition surface is softer and smoother than sharp edges, giving people a more comfortable look and feel and improving safety during installation, preventing the edges from scratching the operator.

[0012] Furthermore, a notch communicated with the mounting groove is provided on the main body. When the electromagnetic sheet needs to be replaced, the existing tool is used to clamp in the notch to lift up the electromagnetic sheet, thereby simplifying the disassembly process and improving replacement efficiency.

[0013] Furthermore, the axial depth of the notch is greater than the depth of the mounting groove, which facilitates contact between the tool and the bottom of the electromagnetic sheet, making replacement of the electromagnetic sheet easier and more convenient.

[0014] Furthermore, a blocking portion is provided in the rapid flow channel, and the blocking portion is used to change the flow speed of the medium. The setting of the blocking portion can make the cooling medium form turbulence in the rapid flow channel, and the cooling medium can more effectively absorb the heat generated by the welding head, thereby improving the cooling efficiency.

[0015] Furthermore, the blocking portion includes a first guiding surface arranged in a constricted shape. When the medium flows through the constricted shape, its speed will be accelerated due to the reduction of the flow area, thereby forming a high-speed flow of the medium.

[0016] Furthermore, the blocking portion also includes a second guide surface arranged in a flared shape. The flared design of the second guide surface can gradually increase the flow area of ​​the cooling medium, thereby slowing down the flow rate of the medium. This design is particularly useful when the medium flows out of the rapid flow channel and enters the buffer channel or the connecting channel. It helps to reduce the impact force of the medium on the subsequent channels and reduce noise and vibration.

[0017] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0032] The utility model has a welding head with a water cooling effect, comprising an integrally formed body 10, the integrally formed body 10 has a compact structure, has no additional seams or connection points, thereby improving the overall stability and durability, and can be mass-produced, a cooling channel 14 is provided in the body 10, the cooling channel 14 is used for the circulation of a medium, and a water inlet 23 for the cooling medium to enter the body 10 and a water outlet 24 for discharging the cooling medium are provided at both ends of the cooling channel 14, and the cooling medium can be water or other medium with a cooling effect.

[0033] A mounting groove 11 is provided on one end face of the main body 10, and an electromagnetic sheet is installed in the mounting groove 11. The shape of the mounting groove 11 is set according to the shape of the electromagnetic sheet. A positioning hole 13 communicating with the cooling channel 14 is provided in the mounting groove 11, and the positioning holes 13 are arranged at intervals in the mounting groove 11. A positioning portion corresponding to the positioning hole 13 is provided on the electromagnetic sheet, and the positioning portion is clamped in the positioning hole 13.

At the same time, it is convenient for the positioning and installation of the electromagnetic sheet to prevent the displacement of the electromagnetic sheet. When the electromagnetic sheet is installed in the mounting groove 11, the electromagnetic sheet and the main body 10 can be connected by welding or filling sealing materials at the connection between the electromagnetic sheet and the mounting groove 11 to prevent leakage of the medium. In order to improve the comfort of installation, the edges in the mounting groove 11 are set as arc transition surfaces. The setting of the arc transition surface can reduce stress concentration and increase the service life of the welding head. At the same time, the arc transition surface is softer and smoother than the sharp edges to prevent the edges from scratching the operator.

[0034] A notch 12 communicating with the mounting groove 11 is provided on the main body 10, and the open end of the notch 12 faces the outer surface of the main body 10.
