Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel coil production and processing, in particular to a device for processing burrs on steel coils. Background Art
[0002] A steel coil, also known as a coiled steel, is obtained by hot-pressing and cold-pressing steel into a coiled shape. During the longitudinal slitting process of the steel coil, burrs will be generated on the surface of the steel strip due to the use of cutting tools to cut the steel coil. Therefore, it is necessary to process the burrs on the steel strip to ensure the smoothness of the steel strip surface. Generally, the burrs cannot be directly processed in the slitting process, but need to be manually polished and trimmed on the steel strip in the subsequent shearing or stamping of finished products. However, since burrs are adverse factors generated during processing, if the burrs are transferred to the next process together with the steel strip, it will not only affect the next process and easily cause the appearance of more defective products, but also the burr treatment of the next-process finished products wastes manpower and time, resulting in a reduction in production efficiency. Content of the Utility Model

Detailed Embodiment
[0016] Next, the technical solution of the present utility model will be described in detail in conjunction with the drawings and preferred embodiments.
[0017] See Figures 1-4, this embodiment provides a burr processing device for steel coils. The device mainly includes a tool holder assembly, a cross beam 1, and a pair of cross beam fixing seats 2. Anti-rotation through holes are provided on both the tool holder assembly and the pair of cross beam fixing seats 2. The cross beam 1 passes through the anti-rotation through holes on the tool holder assembly and the pair of cross beam fixing seats 2. The shape of the anti-rotation through hole matches that of the cross beam 1 to prevent the cross beam 1 from rotating. For example, the cross section of the cross beam 1 and the shape of the anti-rotation through hole are both square or both rectangular, or other shapes that can prevent rotation, which will not be elaborated here. The role of the cross beam is to connect the tool holder assembly and the cross beam fixing seats 2 and provide support for the tool holder assembly. To further reduce the overall weight of the device, the cross beam 1 in this embodiment can adopt a hollow tube structure. At the same time, the material of the cross beam 1 can be common materials such as iron, copper, stainless steel, etc. The positions of the tool holder assembly and the cross beam fixing seats 2 on the cross beam 1 are adjustable. The tool holder assembly can be located between the two cross beam fixing seats 2 or outside any one of the cross beam fixing seats 2. The cross beam fixing seats 2 are fixedly connected to the steel coil slitting equipment. Therefore, this device can be directly fixed on the steel coil slitting equipment, so as to directly process burrs on the steel coil slitting equipment.
[0018] The tool holder assembly includes a tool holder body 3, a scraping knife 4, a first tool sleeve 5, a second tool sleeve 6, a rotary adjusting frame 7, two bearing assemblies, and a burr cleaning assembly. The tool holder body 3 is processed from an iron blank and has a U-shaped opening in the middle. An anti-rotation through hole is opened on one side of the U-shaped opening. The size of the anti-rotation through hole is consistent with the cross section of the cross beam 1, allowing the cross beam 1 to pass through the tool holder body 3. And a set screw hole is provided at the top of the anti-rotation through hole. The set screw 8 is in threaded cooperation with the set screw hole. After the tool holder body 3 is adjusted to the appropriate position on the cross beam 1, the set screw 8 fixes the tool holder body 3 and the cross beam 1 through the set screw hole. Two bearing assemblies are installed on the other side of the U-shaped opening, and the two bearing assemblies are arranged side by side vertically. Each bearing assembly includes a mounting shaft 9, a bearing 10, a spacer sleeve 11, and a fastening nut 12. The mounting shaft 9 passes through the bearing 10, the spacer sleeve 11, and the bearing hole 13 on the tool holder body 3 in sequence and is then threadedly connected to the fastening nut 12. There is a gap between the bearings 10 in the two bearing assemblies. The edge of the material after being processed by the scraping knife 4 passes through this gap. And plugging springs 14 are respectively provided at the positions on the tool holder body 3 that are directly opposite to the bearing holes 13 up and down. During operation, the size of the gap is adjusted through the plugging springs 14 to ensure that the two bearings 10 are in contact with the material and have an operating gap, reducing the impact on the material. When adjusting the size of the gap through the plugging springs 14, the maximum up and down telescopic distance of each bearing 10 is 4 mm, so as to adapt to materials of different thicknesses passing through. Further, as Figure 3 and Figure 4 shown, each bearing assembly includes two bearings 10, and the two bearings 10 are arranged side by side axially on the corresponding mounting shaft 9 to further reduce the impact on the material.
[0019] The scraper 4 is installed in the first knife sleeve 5 and the second knife sleeve 6. The first knife sleeve 5 is placed at the bottom of the U-shaped opening, and the first knife sleeve 5 is fastened to the knife seat body 3 by the fastening bolts 15 inserted through the holes in the outer wall of the knife seat body 3. The fastening bolts 15 also play the role of jacking and adjusting the tightness. The second knife sleeve 6 is connected to the rotating adjustment frame 7 fixed on the knife seat body 3 by screws. The rotating adjustment frame 7 includes a semicircular angle adjustment plate 7-1 perpendicular to the surface of the knife seat body 3. The semicircular angle adjustment plate 7-1 is used to adjust the inclination angle of the scraper 4. After the second knife sleeve 6 slides to a preset position along the semicircular angle adjustment plate 7-1, the screws are tightened to fix it, and the fastening bolts 15 are tightened to fix the first knife sleeve 5. An angle scale can also be provided on the semicircular angle adjustment plate 7-1 to facilitate the observation of the inclination angle value of the scraper 4. Furthermore, the rotation adjustment frame 7 also includes a mounting base 7-2, which is a plate-like structure and is fixedly connected to the tool holder body 3 by screws. The semicircular angle adjustment plate 7-1 is integrally formed with the mounting base 7-2. The semicircular angle adjustment plate 7-1 is perpendicular to the mounting base 7-2, and the semicircular angle adjustment plate 7-1 and the mounting base 7-2 are both located below the anti-rotation through hole.
[0020] The burr cleaning assembly is fixed to one side of the blade holder body 3 where the bearing assembly is located, forming a cleaning area to sweep away the burrs scraped by the scraper 4 from the material surface, ensuring that the burrs are not rolled into the material surface. Specifically, the burr cleaning assembly in this embodiment can sweep away the burrs scraped by the scraper 4 from the material surface by means of a brush or gas.
[0021] When the burr cleaning component uses a brush, such as Figure 4 As shown, the burr cleaning assembly includes a brush 16 and a brush holder 17. The brush holder 17 is T-shaped, and the T-shaped rod is fixedly connected to the tool holder body 3 by a nut. The brush 16 is L-shaped, and one side of the L-shaped is fixed to the top of the brush holder 17 by a screw and a nut. The edge of the material processed by the scraper 4 passes through the bristles at the bottom of the brush 16, thereby sweeping off the burrs on the surface of the material.
[0022] The brush can also be replaced by an air pipe, which can be realized by using the original air pipe of the steel coil slitting equipment. When the burr cleaning component uses gas, the burr cleaning component includes an air pipe and an air pipe clamping frame, the air pipe clamping frame is fixedly connected to the knife holder body 3, the air pipe is clamped and fixed on the air pipe clamping frame, and the air outlet direction of the air pipe is aligned with the contact position between the scraper 4 and the material, and air is blown toward the edge of the material, so as to use the gas to blow off the burrs.
[0023] Generally, the burr appears on one side of the material, either on the left or the right. The mounting holes of the tool holder body 3 are symmetrical, and the mounting directions of the accessories can be adjusted so that the device can handle the burrs appearing on different positions on the left and right.
[0024] This device is used during the operation of the steel coil slitting equipment and is installed on one side in the advancing direction of the material. The material contacts in sequence with the scraping knife 4 first, and then the edge of the material passes through the gap between the bearings 10. By adjusting the inclination angle of the scraping knife 4, the blade contacts the position of the burrs to be processed. During the operation of the material, the scraping knife 4 scrapes off the burrs. The material after being processed by the scraping knife 4 then passes through the gap between the bearings 10. Because there is a sealing spring 14, there is a certain vertical telescopic space between the two groups of bearings 10 to ensure that the material can pass through. The function of the bearings 10 is to ensure the stable operation of the material, reduce the fluctuation amplitude of the material near the scraping knife 4, and ensure the stable contact between the scraping knife 4 and the material.
[0025] The burr processing device can directly process burrs on the slitting equipment, with a fast processing speed and no energy consumption; it replaces the subsequent manual work and solves problems in this process to avoid the expansion of problems.
