Description

Technical Field

[0001] This utility model relates to the field of steel strip production technology, specifically to an edge burr removal device for steel strip production. Background Technology

[0002] In the steel strip production process, removing burrs from the steel strip edges is a crucial step to ensure product quality and smooth subsequent processing. Currently, the widely used edge burr removal devices for steel strip production mainly use cutting tools to cut the edges of the steel strip to remove burrs. However, existing burr removal devices of this type have significant drawbacks. As cutting continues, the cutting tool wears down. Lacking an adaptive position adjustment function, the tool wears down after prolonged cutting, causing its position to change and preventing effective contact with the steel strip edge. This results in incomplete removal of burrs from the steel strip edge, severely impacting the surface quality and dimensional accuracy of the steel strip. This not only reduces the yield rate of steel strip products but may also lead to equipment malfunctions or decreased machining accuracy in subsequent processing, increasing production costs and product defect rates for manufacturers and hindering the high-quality development of the steel strip manufacturing industry. Summary of the Invention

[0003] The main purpose of this utility model is to solve the above-mentioned existing technical problems and provide an edge burr removal device for steel strip production.

[0004] The specific solution of this utility model is: an edge burr removal device for steel strip production, including a bracket with a protective cover installed on it. The protective cover is provided with a conveying assembly for conveying the steel strip. Inside the protective cover is a scraping assembly for removing edge burrs from the steel strip. The scraping assembly includes mounting boxes symmetrically installed inside the protective cover. An adjusting cylinder is installed inside the mounting box. The telescopic end of the adjusting cylinder is connected to an inner frame. A first mounting rod and a second mounting rod are slidably installed on the inner frame. The ends of the first and second mounting rods extending into the inner frame are both connected to the inner frame through support springs. A roller is rotatably installed on the first mounting rod. A scraper is installed on the second mounting rod. A transmission gear is rotatably installed inside the inner frame. A first rack meshing with the transmission gear is installed on the side wall of the first mounting rod. A second rack meshing with the transmission gear is installed on the side wall of the second mounting rod. The first and second racks are arranged radially.

[0005] According to the above technical solution, the roller scraper structure with gear and rack linkage can achieve adaptive elastic scraping of burrs on the edges of steel strips of different thicknesses, thereby improving the cleaning accuracy and equipment versatility.

[0006] Furthermore, in its initial state, the support spring's elastic force pushes the first mounting rod and the second mounting rod to slide outward from the mounting box.

[0007] According to the above technical solution, the first and second mounting rods are pushed outward by the elastic force of the support spring in the initial state, so that the roller and scraper are kept in the extended tendency in advance, ensuring that the steel strip can quickly fit the edge when it enters, and the dynamic adaptive burr removal preparation is achieved through elastic contact.

[0008] Furthermore, the outermost edge of the roller and the scraper are on the same horizontal line.

[0009] According to the above technical solution, by ensuring that the outermost edge of the roller and the scraper are on the same horizontal line, it is ensured that the rolling support of the roller on the edge of the steel strip and the scraping action of the scraper are synchronized and coordinated during the burr removal process, so as to avoid uneven scraping or damage to the surface of the steel strip caused by height difference, and achieve a precise and stable burr removal effect.

[0010] Furthermore, the device also includes an adjustment assembly disposed on the protective cover. The adjustment assembly includes mounting seats symmetrically mounted on the top surface of the protective cover. A threaded sleeve is rotatably mounted inside the mounting seat. A threaded rod is threadedly connected inside the threaded sleeve. A slide is rotatably connected to the bottom end of the threaded rod. The mounting box is mounted on the slide.

[0011] According to the above technical solution, by cooperating with the threaded sleeve and the threaded rod, the mounting box can be moved laterally by manual or drive adjustment of the slide block, so as to realize the precise adjustment of the scraping component to the position of removing burrs on the edge of steel strips of different widths, thereby improving the adaptability of the equipment to steel strip specifications.

[0012] Furthermore, a rotating shaft is rotatably mounted on the protective cover, a worm gear coaxially mounted on the outer wall of the rotating shaft, and a worm wheel is mounted on the outer wall of the threaded sleeve, the worm wheel meshing with the worm gear.

[0013] According to the above technical solution, the threaded sleeve is driven to rotate by the worm gear transmission mechanism, so as to realize the synchronous reverse adjustment of the double-sided scraping components. The self-locking characteristics of the worm gear ensure the positional stability after the width adjustment, thereby improving the equipment's adaptability to steel strips of different specifications and its processing accuracy.

[0014] Furthermore, a guide block is provided on the side of the slide away from the mounting box, and a guide groove is provided on the inner wall of the protective cover for the guide block to slide.

[0015] According to the above technical solution, the guide block and the guide groove on the inner wall of the protective cover are used to limit the movement direction of the slide, avoid deviation or shaking during the adjustment process, and ensure the smoothness and positional accuracy of the lateral movement of the scraping component.

[0016] Furthermore, the protective cover has an inlet and an outlet for the steel strip to enter and exit. A guide frame is provided on the outer wall of the inlet side of the protective cover. A conveying roller is rotatably mounted on the guide frame. An mounting plate is also mounted on the guide frame. Guide rollers are symmetrically slidably mounted on the mounting plate. A pushing cylinder is mounted on the guide frame to push the guide rollers to slide along the mounting plate.

[0017] According to the above technical solution, the steel strip is smoothly conveyed by the conveying rollers on the guide frame. In conjunction with the symmetrical sliding of the guide rollers driven by the push cylinder, adaptive clamping and guiding of steel strips of different widths is achieved, ensuring that the steel strip is accurately aligned with the scraping component, improving the burr removal accuracy and equipment versatility.

[0018] Furthermore, the protective cover is equipped with conveying components at both the inlet and outlet. The conveying components are rotatably mounted on fixed rollers at the inlet and outlet. A slider is slidably mounted on the side wall of the protective cover. A movable roller is rotatably mounted on the slider. A conveying channel for conveying steel strip is formed between the movable roller and the fixed roller. An adjusting cylinder for adjusting the sliding of the slider is installed on the top of the protective cover.

[0019] According to the above technical solution, by driving the slider with the adjusting cylinder to move the movable roller, the width of the conveying channel between the fixed roller and the movable roller can be flexibly adjusted, so as to achieve adaptive clamping and stable conveying of steel strips of different thicknesses.

[0020] Compared with existing technologies, this utility model has the following advantages: The edge burr removal device for steel strip production can adaptively adjust the scraper position in real time according to the edge condition of the steel strip and the wear of the scraper blades. Combined with a stable conveying component, it achieves continuous, efficient, and precise burr removal, significantly improving the surface quality and dimensional accuracy of the steel strip and reducing the product defect rate. The adjustable component allows for flexible and precise adjustment of the scraper height, making the device adaptable to steel strips of different thicknesses and enhancing its versatility. Simultaneously, stable operation reduces equipment wear, lowers equipment replacement and maintenance costs for enterprises, and improves equipment utilization. Attached Figure Description

[0022] See Figure 1-4 This embodiment is a burr removal device for steel strip production, including a bracket 1 on which a protective cover 2 is mounted. The protective cover 2 is equipped with a conveying assembly for conveying the steel strip. Inside the protective cover 2 is a scraping assembly for removing burrs from the steel strip edges. The scraping assembly includes mounting boxes 19 symmetrically installed inside the protective cover 2. An adjusting cylinder 29 is installed inside the mounting box 19. The telescopic end of the adjusting cylinder 29 is connected to an inner frame 24. A first mounting rod 20 and a second mounting rod 21 are slidably mounted on the inner frame 24. The first mounting rod 20 and the second mounting rod 21... One end of each component extending into the inner frame 24 is connected to the inner frame 24 via a support spring 25. A roller 22 is rotatably mounted on the first mounting rod 20, and a scraper 23 is mounted on the second mounting rod 21. A transmission gear 26 is rotatably mounted inside the inner frame 24. A first rack 27 meshing with the transmission gear 26 is mounted on the side wall of the first mounting rod 20, and a second rack 28 meshing with the transmission gear 26 is mounted on the side wall of the second mounting rod 21. The first rack 27 and the second rack 28 are arranged radially. Specifically, the steel belt enters the protective cover 2 under the action of the conveying assembly, and the scraping assembly begins to work. The initial elastic force of the support spring 25 pushes the inner frame 24 and the connected first mounting rod 20 and second mounting rod 21 to slide outwards towards the mounting box 19, causing the roller 22 and the scraper 23 to contact the edge of the steel belt. When the edge of the steel strip is uneven or encounters significant resistance, the roller 22, under pressure, slides towards the inner frame 24. The first mounting rod 20 drives the first rack 27 to move, and through the meshing of the transmission gear 26, the second rack 28 on the second mounting rod 21 moves in the opposite direction, causing the scraper 23 to adjust its position synchronously. This ensures effective removal of burrs from the steel strip edge. Compared to existing technologies where the blade cannot adaptively adjust its position, this structure, through the cooperation of the support spring 25 and the transmission gear 26, achieves adaptive adjustment of the scraper 23's position. Even if the steel strip edge is irregular or the scraper 23 is worn, it can still maintain effective contact with the steel strip edge, continuously removing burrs, improving the surface quality and dimensional accuracy of the steel strip, and reducing the product defect rate.

[0023] Furthermore, in its initial state, the support spring 25 pushes the first mounting rod 20 and the second mounting rod 21 to slide outwards from the mounting box 19. Specifically, in its initial state, the support spring 25 pushes the first mounting rod 20 and the second mounting rod 21 to slide outwards from the mounting box 19, allowing the roller 22 and the scraper 23 to actively extend and closely fit against the edge of the steel strip. This provides initial pressure and contact state for subsequent adaptive position adjustment, ensuring that the roller 22 and the scraper 23 can quickly and stably contact the edge of the steel strip before or just as it enters the cleaning device, without the need for an additional drive mechanism to bring them close to the steel strip.

[0024] Furthermore, the outermost edges of the roller 22 and the scraper 23 are on the same horizontal line. Specifically, since the outermost edges of the roller 22 and the scraper 23 are on the same horizontal line, when the roller 22 rolls along the edge of the steel strip, senses the undulations of the steel strip edge and adjusts its position accordingly, the scraper 23 can move synchronously at the same horizontal height to remove burrs from the edge of the steel strip. The two work together to ensure that the scraper 23 always removes burrs at the height position of the steel strip edge detected by the roller 22, avoiding problems of incomplete removal or over-cutting caused by height difference.

[0025] Furthermore, it also includes an adjustment assembly mounted on the protective cover 2. The adjustment assembly includes mounting seats 12 symmetrically mounted on the top surface of the protective cover 2. A threaded sleeve 13 is rotatably mounted inside the mounting seat 12. A threaded rod 14 is threadedly connected inside the threaded sleeve 13. A slide block 18 is rotatably connected to the bottom end of the threaded rod 14. A mounting box 19 is mounted on the slide block 18. Specifically, rotating the threaded sleeve 13 causes its threaded connection with the threaded rod 14 to move the threaded rod 14 up and down axially, thereby driving the slide block 18 to slide up and down. The mounting box 19 and the scraping assembly mounted on the slide block 18 also move up and down accordingly, realizing the adjustment of the height position of the scraping assembly to accommodate steel strips of different thicknesses.

[0026] Furthermore, a guide block is provided on the side of the slide block 18 away from the mounting box 19, and a guide groove is provided on the inner wall of the protective cover 2 for the guide block to slide. Specifically, when the slide block 18 is pushed up and down by the threaded rod 14, the guide block slides in the guide groove on the inner wall of the protective cover 2, providing guidance and support for the movement of the slide block 18, ensuring the smoothness and straightness of the movement of the slide block 18, and preventing it from deviating or shaking during the movement.

[0027] Furthermore, the protective cover 2 has an inlet and an outlet for the steel strip to enter and exit. A guide frame 3 is provided on the outer wall of the inlet side of the protective cover 2. A conveying roller 4 is rotatably mounted on the guide frame 3. An mounting plate 5 is also mounted on the guide frame 3. Guide rollers 6 are symmetrically slidably mounted on the mounting plate 5. A pushing cylinder 7 is mounted on the guide frame 3 to push the guide rollers 6 to slide along the mounting plate 5. Specifically, the steel strip is first initially guided into the device by the conveying roller 4 on the guide frame 3. The pushing cylinder 7 pushes the guide rollers 6 to slide along the mounting plate 5, which can further adjust and clamp the position of the steel strip, so that the steel strip enters the protective cover 2 in an accurate position and posture. The conveying components at the inlet and outlet of the protective cover 2 are adjusted by the adjusting cylinder 11 to adjust the slider 9, which drives the movable roller 10 to move, changing the distance between the movable roller 10 and the fixed roller 8, adapting to steel strips of different thicknesses and providing stable conveying force to ensure that the steel strip is transported smoothly in the device.

[0028] Furthermore, both the inlet and outlet of the protective cover 2 are equipped with conveying components. The conveying components are rotatably mounted on the fixed rollers 8 at the inlet and outlet. A slider 9 is slidably mounted on the side wall of the protective cover 2. A movable roller 10 is rotatably mounted on the slider 9. A conveying channel for conveying steel strip is formed between the movable roller 10 and the fixed roller 8. An adjusting cylinder 11 for adjusting the sliding of the slider 9 is installed on the top of the protective cover 2. Specifically, the conveying components installed at the inlet and outlet of the protective cover 2, through the adjustment cylinder 11, adjust the slider 9, driving the movable roller 10 to move and change the distance between the movable roller 10 and the fixed roller 8, thus adapting to the conveying of steel strips of different thicknesses. At the same time, the conveying channel formed between the movable roller 10 and the fixed roller 8 clamps and guides the steel strip, ensuring that the steel strip is conveyed smoothly within the device. This works in conjunction with the scraping component to complete the burr removal work. The conveying component is flexibly adjustable to adapt to various specifications of steel strips, ensuring the stability and accuracy of the steel strip conveying within the device, providing good working conditions for the scraping component, improving the overall quality and efficiency of steel strip burr removal, and enhancing the applicability and practicality of the device.

[0029] The working principle of this embodiment is as follows: During use, the steel strip is first initially guided by the conveying roller 4 on the guide frame 3. The cylinder 7 drives the guide roller 6 to slide along the mounting plate 5, adjusting and clamping the steel strip to ensure it enters the protective cover 2 with a precise posture. At the feed inlet of the protective cover 2, the adjusting cylinder 11 of the conveying component adjusts the slider 9, driving the movable roller 10 to move. This, in conjunction with the fixed roller 8, forms a conveying channel adapted to the thickness of the steel strip, smoothly feeding the steel strip into the device. After entering the protective cover 2, the scraping component begins to function. The initial elasticity of the support spring 25 pushes the inner frame 24, the first mounting rod 20, and the second mounting rod 21, causing the roller 22 and the scraper 23 to fit tightly against the edge of the steel strip. When the edge of the steel strip is uneven or generates significant resistance, the roller 22 is pressed and slides towards the inner frame 24. The first mounting rod 20 drives the first rack 27 to move. Through the meshing of the transmission gear 26 and the second rack 28, the scraper 23 adjusts its position synchronously, always maintaining effective scraping of the burrs on the edge of the steel strip. To process steel strips of varying thicknesses, the rotating shaft 16 can be rotated. Through the meshing of the worm gear 17 and worm wheel 15, the threaded sleeve 13 rotates, causing the threaded rod 14 to move axially. This, in turn, causes the slide block 18, mounting box 19, and scraping assembly to slide up and down, thus adjusting the height. During the movement of the slide block 18, the guide block slides within the guide groove on the inner wall of the protective cover 2, ensuring smooth movement. Finally, the steel strip is conveyed through the conveying assembly at the outlet of the protective cover 2 and output to the device in a stable posture, completing the entire burr removal process.
