Technical Field
[0001] This utility model relates to the field of pre-processing technology for flat steel heat treatment, and in particular to an auxiliary device for flat steel heat treatment. Background Technology
[0002] Before heat treatment of flat steel, the oxide layer, oil, and impurities on the surface must be removed to ensure uniform heating, reduce defects, and improve the quality of the final product. The presence of the oxide layer affects heat conduction, causing localized temperature deviations, which can lead to problems such as uneven microstructure, decarburization, or cracking. Furthermore, the oxide scale may peel off at high temperatures, contaminating the furnace environment and affecting the processing of other workpieces.
[0003] Existing auxiliary equipment for removing oxide scale from flat steel surfaces has a relatively simple structure and cannot clean the flat steel to different degrees according to its oxidation level. For light oxidation, strong cleaning may excessively wear down the surface of the flat steel, while for heavy oxidation, the cleaning force is insufficient, and the residual oxide scale affects the heat treatment quality. Summary of the Invention
[0004] The purpose of this invention is to solve the problems of existing auxiliary equipment for removing oxide scale from the surface of flat steel, which has a relatively simple structure and cannot clean the flat steel to different degrees according to the degree of oxidation. For light oxidation, strong cleaning may excessively wear down the surface of the flat steel, while for heavy oxidation, the cleaning force is insufficient and the residual oxide scale affects the heat treatment quality. Therefore, this invention proposes an auxiliary equipment for heat treatment of flat steel.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A heat treatment auxiliary device for flat steel includes a vertical frame and a workbench. A vertical groove is provided on the side of the vertical frame, and a support base is fixedly provided at the bottom of the vertical frame. A first cleaning component and a second cleaning component for scraping off the oxide layer on the surface of the flat steel are arranged sequentially on the side of the vertical groove on the vertical frame.
[0007] The first cleaning component can scrape off the oxide layer on the surface of lightly oxidized flat steel. The first cleaning component includes a wire brush roller, a drive motor, and a support block. The support block is movably inserted into the vertical groove, and the drive motor is fixedly installed on the side of the support block.
[0008] Optionally, the second cleaning assembly can scrape off the oxide layer on the surface of heavily oxidized flat steel. The second cleaning assembly includes an extension plate, a common pipe, and a distribution pipe. The common pipe is fixedly provided on the side of the extension plate, and the distribution pipe is provided at equal intervals at the bottom of the common pipe.

[0009] Optionally, the output end of the drive motor is fixedly connected to one end of the wire brush roller, and the other end of the wire brush roller is rotatably connected to the side of the drive block. There are two sets of drive blocks, and the common thread of the two sets of drive blocks is screwed into both ends of the outer wall of the bidirectional screw.
[0010] The two ends of the bidirectional screw are rotatably connected to the two ends of the vertical groove. The outer wall of the bidirectional screw is symmetrically provided with external threads in opposite directions. When the bidirectional screw rotates, it will drive the two driving blocks to move closer or further apart.
[0011] Optionally, one end of each of the two common pipes is fixedly connected to one end of the same common flexible hose, and a water supply pipe is fixedly connected to the middle of the common flexible hose.
[0012] Optionally, the end of the extension plate away from the common pipe is fixedly connected to the side of the drive block.
[0013] Optionally, the top of the support base is hollow, a vertical frame is fixedly installed on the top of the support base, and workbenches are symmetrically fixedly installed on both sides of the vertical frame.

[0015] Compared with the prior art, the present invention has the following advantages:
[0016] 1. The main structure of this utility model includes a first cleaning component and a second cleaning component. The first cleaning component, based on a wire brush roller, can clean flat steel with a small degree of oxidation and scrape off the thin oxide layer on the surface of the flat steel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-3 A heat treatment auxiliary device for flat steel includes a vertical frame 1 and a workbench 7. A vertical groove 2 is provided on the side of the vertical frame 1, and a support base 6 is fixedly provided at the bottom of the vertical frame 1. A first cleaning component and a second cleaning component for scraping off the oxide layer on the surface of the flat steel are arranged sequentially on the side of the vertical groove 2 on the vertical frame 1. The first cleaning component can scrape off the oxide layer on the surface of lightly oxidized flat steel. The first cleaning component includes a wire brush roller 8, a drive motor 9, and a support block 10. The support block 10 is movably inserted into the vertical groove 2, and the drive motor 9 is fixedly provided on the side of the support block 10. The second cleaning component can scrape off the oxide layer on the surface of heavily oxidized flat steel.
[0024] The second cleaning assembly includes an extension plate 11, a common pipe 12, and a distribution pipe 13. The common pipe 12 is fixedly installed on the side of the extension plate 11, and the distribution pipe 13 is equidistantly installed at the bottom of the common pipe 12. The length of the distribution pipe 13 is the same as the length of the wire brush roller 8. The output end of the drive motor 9 is fixedly connected to one end of the wire brush roller 8, and the other end of the wire brush roller 8 is rotatably connected to the side of the drive block 3. The surface of the wire brush roller 8 has curled steel wires equidistantly distributed, similar to a wire brush, which can scrape off the oxide layer attached to the surface of the flat steel.
[0025] There are two sets of drive blocks 3. The two sets of drive blocks 3 are screwed into the two ends of the outer wall of the bidirectional screw 31 by a common thread. The two ends of the bidirectional screw 31 are rotatably connected to the two ends of the vertical groove 2. The outer wall of the bidirectional screw 31 is symmetrically provided with external threads of opposite directions. When the bidirectional screw 31 rotates, it will drive the two drive blocks 3 to move closer or further away from each other. The top of the bidirectional screw 31 is additionally provided with a rocker wheel to facilitate the rotation of the bidirectional screw 31.
[0026] One end of each of the two common pipes 12 is fixedly connected to one end of the same common hose 4. A water supply pipe 5 is fixedly connected to the middle of the common hose 4. The end of the extension plate 11 away from the common pipes 12 is fixedly connected to the side of the drive block 3. The top of the support base 6 is hollow. A vertical frame 1 is fixedly installed on the top of the support base 6. A workbench 7 is symmetrically installed on both sides of the vertical frame 1. An avoidance groove 71 is opened on the side of the workbench 7 near the common pipes 12. The bottom height of the vertical groove 2 is much lower than the top height of the workbench 7. The water supply pipe 5 is connected to an external high-pressure water source during use. The common hose 4 is made of soft rubber, so that high-pressure water can still be obtained from the water supply pipe 5 when the two common pipes 12 are close to or far apart.
[0027] The specific implementation steps and principles of this utility model are as follows:
[0028] Connect the water supply pipe 5 to a high-pressure water source, insert the flat steel to be processed into the top of the workbench 7, and insert the flat steel between two wire brush rollers 8. Manually rotate the bidirectional screw 31 to drive the two wire brush rollers 8 to adhere to the surface of the flat steel. The worker observes the degree of oxidation on the surface of the flat steel and chooses to use high-pressure water or the two wire brush rollers 8 driven by the drive motor 9 to scrape off the oxide layer on the surface of the flat steel. Repeat the rotation of the flat steel to polish the surface of the flat steel.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
