Description

Technical Field

[0001] The utility model relates to the technology of the impedance field, in particular to a high-efficiency energy-saving impedance for high-frequency welded pipes. Background Art

[0002] Impeders (also known as carbon rods) are essential tools for high-frequency welded pipe production and play a key role in high-frequency welding technology. They increase the impedance of the steel pipe's inner wall, effectively altering the distribution of the induced current within the tube, allowing as much current as possible to converge on the fusion zone at the edge of the V-shaped zone to be welded. This improves induction welding efficiency, weld quality, production speed, and unit energy consumption.

[0003] The main structure of the current impeder includes a housing and a magnetic core disposed within the housing. This type of impeder generates significant heat during use. However, the impeder in the prior art cannot be adequately cooled during operation, resulting in very low operating efficiency and a short service life. Therefore, it is necessary to improve the current impeder. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a high-efficiency energy-saving impedance for high-frequency welded pipes, which can effectively solve the problems of low working efficiency and short service life of the existing impedance.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-efficiency energy-saving impedance device for high-frequency welded pipes comprises a shell, a front joint, a rear joint, a cooling pipe and a magnetic core; the shell is a hollow tubular structure having a housing chamber therein; the front joint and the rear joint are respectively fixedly mounted on the front and rear ends of the shell and cover the front and rear openings of the housing chamber, the front joint having an output port, and the rear joint having an input port; the cooling pipe is arranged in the housing chamber, the front and rear ends of the cooling pipe are respectively fixedly connected to the front joint and the rear joint, and the front and rear openings of the cooling pipe are respectively connected to the output port and the input port; the magnetic core is sleeved outside the cooling pipe and is located in the housing chamber.

[0007] Preferably, the shell is an epoxy resin tube.

[0008] Preferably, one end of the front connector is embedded in the front end opening of the accommodating cavity and is screwed and fixed to the front end of the shell, and the other end of the front connector is in a nut shape.

[0009] Preferably, one end of the rear connector is embedded in the rear end opening of the accommodating cavity and is screwed and fixed to the rear end of the shell, and the other end of the rear connector is in a nut shape.

[0010] Preferably, the shell is a round tube.

[0011] Preferably, the center of the magnetic core has a through hole, and the cooling tube is located in the through hole.

[0012] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] By co-arranging the front joint, the rear joint and the cooling pipe, a cooling channel is formed by utilizing the front joint, the rear joint and the cooling pipe. During operation, cooling water can be introduced into the cooling channel to fully cool the magnetic core, thereby effectively improving the working efficiency of the impedance device, and at the same time extending its service life, reducing consumption and lowering production costs.

[0023] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the present invention, including a shell 10, a front connector 20, a rear connector 30, a cooling tube 40 and a magnetic core 50.

[0024] The housing 10 is a hollow tubular structure having an internal cavity 11. In this embodiment, the housing 10 is an epoxy resin tube, and is a round tube.

[0025] The front connector 20 and the rear connector 30 are respectively mounted and fixed at the front and rear ends of the housing 10 and cover the front and rear openings of the accommodating chamber 11. The front connector 20 has an output port 21, and the rear connector 30 has an input port 31. In this embodiment, one end of the front connector 20 is embedded in the front opening of the accommodating chamber 11 and is screwed and fixed to the front end of the housing 10. The other end of the front connector 20 is nut-shaped, which is convenient for disassembly and assembly using tools and is firmly installed. One end of the rear connector 30 is embedded in the rear opening of the accommodating chamber 11 and is screwed and fixed to the rear end of the housing 10. The other end of the rear connector 30 is nut-shaped, which is convenient for disassembly and assembly using tools and is firmly installed.

[0026] The cooling pipe 40 is disposed within the accommodating cavity 11. The front and rear ends of the cooling pipe 40 are fixedly connected to the front connector 20 and the rear connector 30, respectively. The front and rear openings of the cooling pipe 40 are respectively connected to the output port 21 and the input port 31. In this embodiment, the cooling pipe 40 is a circular metal tube with good thermal conductivity. Furthermore, the cooling pipe 40 is coaxially disposed with the housing 10.

[0027] The magnetic core 50 is sleeved outside the cooling tube 40 and located in the accommodating cavity 11. In this embodiment, the magnetic core 50 has a through hole 51 at its center, and the cooling tube 40 is located in the through hole 51. In addition, the magnetic core 50 is in the shape of an elongated strip with a circular cross-section. The magnetic core 50 is coaxial with the housing 10 and suspended in the accommodating cavity 11.

[0028] The method of using this embodiment is described in detail as follows:

[0029] Place this product inside the tube to be welded, adjust the position, and set an induction coil on the outside of the tube. After the induction coil is energized, the induction coil and the magnetic core 50 cooperate with each other by magnetic induction, so that the tube is heated for welding. During the welding process, sufficient cooling water is introduced into the cooling pipe 40 from the input port 31 of the rear joint 30 to cool the magnetic core 50 and ensure the normal operation of the magnetic core 50. The cooling water flows out from the output port 21 of the front joint 20, so that the working efficiency of the impedance is effectively improved, while also extending its service life, reducing consumption, and reducing production costs.
