Description

Technical Field

[0001] This application relates to the technical field of eddy current heating auxiliary structures, and in particular to a protective structure for an eddy current heating device. Background Technology

[0002] Eddy current heating is a commonly used heating method in existing workpiece connection and installation processes. In the production of refractory nozzle slide plates used in steelmaking, some require the addition of metal rings for reinforcement at their edges. Heating the metal rings during the fitting process makes the fitting faster, and the heated metal rings, after subsequent treatment, improve the connection's strength and extend its service life. Existing installation processes use eddy current heating, but existing eddy current equipment is in a fixed position, while the processing of nozzle slide plates requires continuous operation of subsequent processes. Existing eddy current heating equipment cannot handle this well, especially since the workpieces are refractory materials and are relatively heavy. Moving them back and forth in and out of the eddy current area is labor-intensive and can easily lead to contact with the high-frequency coils of the eddy current, causing damage to the equipment. Therefore, it is necessary to improve the structure of existing heating equipment to solve these problems. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this application is to provide a protective structure for eddy current heating equipment that improves the ease of operation, reduces the risk of equipment damage, lowers the labor intensity of personnel handling, and accelerates production efficiency.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] To better understand the technical solutions presented in the embodiments of this application, the working principle of the protective structure of existing eddy current heating equipment will first be introduced.

[0021] In the existing production process of sprue slide plates, metal strips are wrapped around the perimeter to improve the strength of the refractory brick edges. However, due to the poor performance of the metal strips and the inconvenience of fitting them together, heat treatment is required to expand them. The performance of the heated metal strips is improved, making them easier to install and allowing the edges to be pressed together after cooling, thereby enhancing the strength of the workpiece. Among the existing heating methods, eddy current heating has the advantages of high speed and fixed heating position, and has less impact on the workshop environment. However, when using it, the workpiece needs to be placed in its induction coil. Moving the workpiece back and forth can easily cause it to collide with the coil, leading to equipment damage. Therefore, the structure of the existing eddy current heating equipment needs to be improved to solve these problems.

[0022] Please see Figure 1 and Figure 2 This application discloses a protective structure for an eddy current heating device, comprising: a connecting base plate 1, a support frame 2, an eddy current generating module 3, an annular sleeve 4, a support rod 5, an induction ring body 6, an electric telescopic rod 7, a placement seat 8, a connecting seat 9, a connecting rod 10, a sliding seat 11, and a connecting hole 12. The connecting base plate 1 is rectangular in shape. The support frame 2 is fixedly connected to the surface of the left end of the connecting base plate 1. The eddy current generating module 3 is fixedly connected to the upper end of the support frame 2. The lower end of the annular sleeve 4 is fixedly connected to the support rod 5 at equal intervals. The lower end of the support rod 5 is fixedly connected to the upper surface of the connecting base plate 1. The middle of the annular sleeve 4... The annular groove is provided in the part, and the sensing ring body 6 is connected in the annular groove in the middle of the annular sleeve 4. The output end of the eddy current generating module 3 is connected to the sensing ring body 6. The electric telescopic rod 7 is fixedly connected at intervals to the upper surface of the connecting base plate 1 corresponding to the lower end of the annular sleeve 4. The upper end of the placement seat 8 is open and is fixedly connected to the upper end of the electric telescopic rod 7. The connecting seat 9 is fixedly connected to the lower surface of the middle position of the placement seat 8. The connecting rod 10 is symmetrically fixedly connected to both sides of the connecting seat 9. The sliding seat 11 is slidably connected to the connecting rod 10 on both sides respectively. The connecting hole 12 is opened on the upper surface of the sliding seat 11 respectively.

[0023] Specifically, the connecting base plate 1 provides overall support, ensuring a fixed position after installation and allowing for direct use after relocation within the workshop. The support frame 2 supports the eddy current generating module 3 to a certain height for easy manual operation. The annular sleeve 4 is connected to a certain height via support rod 5, firmly maintaining it in a convenient construction position. The induction ring body 6 is located inside the annular sleeve 4 for protection. The annular sleeve 4 can be made of non-metallic high-temperature resistant materials such as refractory ceramics that do not generate eddy currents. The electric telescopic rod 7 can change the height of the placement seat 8, allowing it to raise or lower the workpiece. The placement seat 8 carries the workpiece to the middle position of the annular sleeve 4, thereby achieving heating treatment of the metal strips on the workpiece. The connecting seat 9 can be used to install the connecting rod 10, and then the sliding seat 11 can be movably connected to the connecting rod 10. The sliding seat 11 can move up and down with the placement seat 8, driving other surrounding equipment or tools to move as well. It can also support actions such as knocking and prying. The connecting hole 12 can also be used for connecting equipment. The material of the placement seat 8 is the same as that of the annular sleeve 4, which is a refractory material. The placement seat 8 can pass vertically through the interior of the annular sleeve 4, and its lower end is lower than the lower end of the annular sleeve 4 to prevent the connecting rod 10 from touching the bottom of the annular sleeve 4. This structure can lift the transported workpiece for heating treatment, which helps to increase the production speed. At the same time, it is easy to install in the existing workshop, with good installation flexibility. Compared with the existing manual operation, it greatly improves the processing efficiency and reduces the labor intensity of personnel.

[0026] Please see Figure 2 As another specific embodiment provided in the application, it also includes a heat insulation pad 14, which is disposed on the lower surface of the placement seat 8.

[0027] Specifically, the heat insulation pad 14 can be made of composite materials such as high-temperature resistant asbestos board or high-temperature resistant ceramic to prevent the metal strip on the upper workpiece from heating up under eddy current and then conducting downwards, thus preventing the electric telescopic rod 7 at the lower end from being damaged by heat.

[0028] Please see Figure 1 As another specific embodiment provided in the application, it also includes a sealing ring 15, which is fitted and connected to the surface of the upper end of the annular sleeve 4.

[0029] Specifically, the sealing ring 15 can seal the upper end of the annular sleeve 4, thus sealing the sensing ring body 6, preventing dust from accumulating on its surface, reducing malfunctions and damage, and helping to extend its service life.

[0030] Please see Figure 2 As another specific embodiment provided in the application, it also includes a positioning nut 16, which is threadedly connected to the lower end of the sliding seat 11, and the ends of the positioning nut 16 are respectively engaged with the surface of the connecting rod 10.

[0031] Specifically, the positioning nut 16 can limit the position of the adjusted sliding seat 11, thereby keeping some support points or equipment connection positions in a certain position, which is convenient for use when processing workpieces and meets the needs of actual scenarios.

[0032] Please see Figure 2 As another specific embodiment provided in the application, it also includes a connecting strip 17, which is fixedly connected to the lower surface of the placement seat 8, and the lower end of the connecting strip 17 is fixedly connected to the upper end of the electric telescopic rod 7.

[0033] Specifically, the connecting strip 17 can support the bottom of the base 8 near the center, increasing its strength and ensuring the overall stability during the lifting process.

[0034] Please see Figure 1 As another specific embodiment provided in the application, it also includes mounting holes 18, which are equidistantly formed on the surface of the connecting base plate 1 near the edge.

[0035] Specifically, the mounting hole 18 allows the connecting base plate 1 to be securely installed at the workstation or other support platform, making the connection operation convenient.

[0037] Specifically, the control switch 19 can control the eddy current generating module 3 and the electric telescopic rod 7 separately, so that the workpiece heating action can be carried out automatically, reducing personnel handling and improving processing efficiency.
