Description

Technical Field

[0001] The present application relates to the technical field of inductor manufacturing, and in particular to an inductor for a welding machine. Background Art

[0002] The inductor mounting structure is a key component in welding equipment, widely used in various welding processes. With the advancement of industrial automation, the performance and reliability of welding machines are receiving increasing attention. The design of the inductor mounting structure directly impacts the efficiency and service life of the welding machine. Traditional inductor mounting structures typically use a simple metal frame and screw fixings. While cost-effective, they have certain limitations in high-frequency and high-current applications. To improve welding machine performance, a more efficient and stable inductor mounting structure is needed to meet increasingly stringent user requirements.

[0003] Utility model patent announcement number CN217426532U discloses an electronic component, specifically a gapped annular differential mode inductor. The plastic shell of the utility model is formed by plugging two cylinders of different diameters together. The magnetic ring is arranged in the plastic shell. The magnetic ring is provided with a gap groove. The material of the magnetic ring is amorphous, and a coil is wound on the plastic shell. The advantage of the utility model is that the amorphous magnetic ring used in the inductor has a gap groove on the magnetic ring, which increases the saturation current and stored energy, reduces the residual magnetism of the magnetic ring, and can reduce the operating temperature. Secondly, the plastic shell is formed by plugging two cylinders of different diameters together, which makes the magnetic ring and the coil have better insulation, and can prevent the magnetic ring and the coil from breaking down due to the gap between the two shells during operation. Since heat will affect the operation of the inductor during the operation of the welding machine, the effect of the inductor in filtering out noise will be reduced. Summary of the Invention

[0004] The purpose of this application is to provide an inductor for a welding machine to solve the problem that the heat generated by the welding machine affects the inductance performance.

[0005] The inductor for a welding machine provided in this application adopts the following technical solution:

[0006] An inductor for a welding machine comprises:

[0007] The partition plate is provided with a mounting opening;

[0008] There are two magnetic blocks, both of which pass through the partition plate and are installed in the installation opening;

[0009] There are two magnetic columns, each located on one side of the partition plate and between the two magnetic blocks, forming a magnetic circuit together with the magnetic blocks. The magnetic columns include several layers of silicon steel sheets, which are stacked.

[0010] The coil is wound around the magnetic column on one side of the partition plate.

[0011] By adopting this technical solution, the magnetic column wrapped around the coil is isolated outside the welder using a separator plate, thereby reducing the impact of heat generated during operation on the inductor. Furthermore, the coil located outside the welder can cooperate with the air duct to ensure the stability and heat dissipation of the welder under high load. A magnetic column is also provided on the other side of the separator plate, allowing the magnetic column to be fixed to the separator plate while forming a closed magnetic circuit, enabling the inductor to operate normally. The magnetic column, composed of multiple layers of silicon steel sheets, has high initial magnetic permeability and low cost, which is beneficial for improving inductor performance.

[0012] Optionally, one end of the magnetic column is connected to the magnetic block, and a gap is formed between the other end of the magnetic column and the magnetic block.

[0013] By adopting the above technical solution, the gap can reduce the magnetic permeability, increase the saturation current, increase the ability to store energy and reduce the residual magnetism.

[0014] Optionally, the magnetic block is provided with a connecting groove, and the connecting groove corresponds to the magnetic column.

[0015] By adopting the above technical solution, the connection groove can provide partial support for the connection between the magnetic column and the magnetic block, thereby making the connection between the magnetic block and the magnetic column more stable and facilitating the normal operation of the inductor.

[0016] Optionally, the gap is located between the magnetic column and the bottom surface of the connecting groove.

[0017] By adopting the above technical solution and arranging the gap in the connecting groove, the gap is not easily affected by the outside, thereby maintaining the stability of the magnetic circuit performance.

[0018] Optionally, a limiting strip is provided on one side of the connecting slot to prevent the magnetic column from falling out of the connecting slot.

[0019] By adopting the above technical solution, since only a small part of the magnetic column protrudes into the connection groove, in order to prevent the magnetic column from falling off due to severe vibration during the operation of the welding machine, a limit strip is provided to make the connection between the magnetic column and the magnetic block more stable.

[0020] Optionally, the partition plate is further provided with a mounting notch and a mounting hole.

[0021] By adopting the above technical solution, the additional mounting notches and mounting holes provided on the partition plate enable the partition plate to be conveniently connected and fixed to the external structure, thereby improving the convenience and stability of installation.

[0022] Optionally, the coil includes an inner ring and an outer ring, the inner ring is wound around the outside of the magnetic column, and the outer ring is wound around the outside of the inner ring.

[0023] By adopting the above technical solution, the tight winding of the inner and outer rings helps to reduce the looseness and deformation of the coil and improve the stability of the overall structure.

[0024] Optionally, the two magnetic columns are arranged in parallel.

[0025] By adopting the above technical solution, the parallel arrangement of magnetic columns can improve the stability of the closed magnetic circuit, thereby improving the inductance performance.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The inductor can stabilize the current, converting the continuous DC power supply in the circuit into a high-frequency pulse power supply, achieving high-low frequency conversion during welding. In this process, the inductor controls the stability of the welding arc by hindering the change of current, thereby ensuring the welding quality. By using a partition plate to isolate the magnetic column wrapped around the coil outside the welder, the effect of the heat generated by the welder during operation on the inductor is reduced. A magnetic column is also provided on the other side of the partition plate, and is connected and supported by a magnetic block, so that the magnetic column can be fixed on the partition plate while forming a magnetic circuit, allowing the inductor to work normally.

[0028] 2. The gap can reduce the magnetic permeability, increase the saturation current, increase the ability to store energy and reduce the residual magnetism;

[0029] 3. By arranging the gap in the connection groove, the gap is not easily affected by external factors, thereby maintaining the stability of the magnetic circuit performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] An inductor for welding machine, referring to Figure 1 and 2, comprising a partition plate 1, a magnetic block 2, a magnetic column 3 and a coil 4, wherein the partition plate 1 is provided with an installation opening 11; there are two magnetic blocks 2, which pass through the partition plate 1 and are arranged in the installation opening 11; there are two magnetic columns 3, which are arranged in parallel, one on each side of the partition plate 1, and are arranged between the two magnetic blocks 2, forming a magnetic circuit together with the magnetic blocks 2; one end of the magnetic column 3 is connected to the magnetic block 2, and a gap 5 is formed between the other end and the magnetic block 2; the coil 4 is wound around the magnetic column 3 on one side of the partition plate 1. The magnetic block 2 is supported by the partition plate 1, and the magnetic column 3 is supported by the magnetic block 2, so that the magnetic column 3 can be installed and fixed with the support of the partition plate 1. Under the isolation of the partition plate 1, the influence of heat on the coil 4 can be reduced during the operation of the welding machine, thereby making the inductor work stable and able to operate normally in a high temperature environment.

[0036] Reference Figure 1 and 2 , the partition plate 1 also includes a mounting notch 12 and a mounting hole 13. The mounting notch 12 is an opening structure located at the edge of the partition plate 1, which is used to facilitate the assembly of the magnetic block 2 and the magnetic column 3 and reduce obstacles during the assembly process. The mounting hole 13 is used to fix the entire inductor fixing structure during the final installation to ensure its stability and reliability. The structural design of the partition plate 1 needs to take into account its installation stability and the function of assisting in fixing the magnetic block 2. The partition plate 1 can be made of metal or plastic materials with sufficient mechanical strength, such as steel plates, aluminum alloy plates or engineering plastic plates. For example, the thickness of the partition plate 1 can vary within a certain range, and the specific size can be adjusted according to actual needs. The mounting port 11 on the partition plate 1 is used to fix the magnetic block 2, and the mounting port 11 has space for the magnetic column 3 to pass through, so that the magnetic column 3 and the magnetic block 2 can be installed on one side of the partition plate 1.

[0037] Reference Figure 2 and 3 There are two magnetic blocks 2, which are die-cast from magnetic powder. The magnetic column 3 includes four stacked silicon steel sheets 31. The magnetic block 2 is provided with a connecting groove 21, which is arranged corresponding to the magnetic column 3. One end of the magnetic column 3 is inserted into the connecting groove 21 and connected to the bottom surface of the connecting groove 21, and the other end of the magnetic column 3 is located at the edge of the connecting groove 21, so that a gap 5 is formed between the magnetic column 3 and the bottom surface of the connecting groove 21, so that the gap 5 is located in the connecting groove 21. By arranging the gap 5 in the connecting groove 21, the gap 5 can avoid interference from external substances, thereby ensuring the stability of the inductance performance.

[0038] Reference Figure 2 A limiting strip 22 may be provided on one side of the connection slot 21 to prevent the magnetic column 3 from falling out of the connection slot 21. The design of the limiting strip 22 ensures a stable connection between the magnetic column 3 and the magnetic block 2, and also facilitates positioning of the magnetic column 3 during assembly.

[0039] Reference Figure 2 and3 , the coil 4 is used to generate an electromagnetic effect, thereby achieving the effect of filtering out noise. The coil 4 includes an inner ring 41 and an outer ring 42. The inner ring 41 is wound around the outside of the magnetic column 3, and the outer ring 42 is wound around the outside of the inner ring 41, and they work together. The specific parameters of the coil 4, such as the number of turns, wire diameter, etc., need to be adjusted according to the actual filtering requirements. Usually, the coil 4 can use copper or aluminum as the conductive material, the wire diameter can vary within a certain range, and the total number of turns can vary within a certain range. In order to better fix and dissipate heat, the coil 4 can be additionally treated with insulating resin or a cooling system. The inner ring 41 and the outer ring 42 are respectively connected to the power supply, so that the current of the inner and outer rings 42 can be adjusted independently, thereby improving the efficiency and flexibility of noise filtering.

[0040] The implementation principle of the embodiment of the present application is as follows: the mounting opening 11 on the partition plate 1 determines the distance between the magnetic blocks 2 while fixing the magnetic blocks 2, so that the magnetic column 3 can form a gap 5 with the magnetic block 2. And the coil 4 is wound on the magnetic column 3 on one side of the partition plate 1, so that the heat generated on the other side can be partially isolated by the partition plate 1, so that the coil 4 is less affected by the heat and the stability is improved. The design of the mounting hole 13 and the mounting notch 12 facilitates the assembly and final fixation of the device, and improves the practicality of the entire filtering device. The design of the connecting groove 21 and the limiting strip 22 on the magnetic block 2 ensures the stability of the magnetic column 3 during use, and the gap 5 between the magnetic column 3 and the magnetic block 2 can effectively improve the inductance performance.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
