Description

Technical Field

[0001] This utility model relates to the field of finishing mill technology, specifically to a baffle for the upper guard plate of a finishing mill. Background Technology

[0002] The upper guard plate at the F1-6 inlet of the 1750 finishing mill is installed at the mill inlet to seal the cooling water of the work rolls, preventing the cooling water from flowing onto the surface of the intermediate strip and causing abnormal steel temperature. Secondly, the guard plate also serves as the guide plate for the dust suction port of the finishing mill's dust removal pipeline, guiding dust and other particles generated during the rolling process to the suction port, enhancing the on-site dust removal effect. In the high temperature and high humidity environment, dust and other particles adhere to the back of the upper guard plate, forming rust and ash. During the rolling process, due to equipment vibration, the upper guard plate lacks a device to prevent the adhered rust and ash from peeling off, causing them to fall onto the upper surface of the intermediate strip, resulting in foreign matter being pressed into the strip surface, thus affecting the production quality of the strip. Utility Model Content

[0003] The purpose of this utility model is to provide a baffle for the upper guard plate of a finishing mill, so as to solve the problem that during the rolling process, due to equipment vibration, the lack of a device to prevent the adhesion of rust and dust after the upper guard plate falls onto the upper surface of the strip, causing foreign objects to be pressed into the surface of the strip.

[0004] To achieve the above objectives, the basic solution provided by this utility model is as follows: a baffle for a finishing mill upper guard plate, comprising an upper guard plate and a mounting plate, the upper guard plate and the mounting plate being bolted together, a rotating tube being fixedly connected to both ends of the mounting plate, a rotating rod being rotatably connected inside the rotating tube, a baffle being fixedly connected to the rotating rod, an adjusting plate one being fixedly connected to both ends of the mounting plate, and an adjusting plate two being detachably connected to both ends of the baffle, each adjusting plate one having a fan-shaped groove one, each adjusting plate two sliding within the fan-shaped groove one, each adjusting plate one being provided with a limiting component for fixing the adjusting plate two, and a scraper being detachably connected to the mounting plate, the scraper being provided with a moving component for moving the scraper.

[0005] The principle and beneficial effects of this utility model are as follows: According to actual needs, the angle of the baffle is adjusted by sliding the second adjusting plate in the first sector groove. After the angle is adjusted, it is fixed by the limiting component. The baffle catches the rust and dust that fall due to equipment vibration, reducing the amount of rust and dust falling onto the upper surface of the strip and being pressed into the strip surface. When there is too much rust and dust on the baffle, the scraper is moved by the moving component to remove the rust and dust from the baffle, thus increasing the practicality of the device.

[0006] Option 2, a preferred embodiment of the basic option, includes two movable rods, two pins, two limiting rings, and several limiting blocks. Each movable rod is fixedly connected to an adjusting plate, and each limiting block is fixedly connected to an adjusting plate. Each adjusting plate has an arc-shaped through hole on one side. Each movable rod rotatably passes through the arc-shaped through hole and is connected to the limiting ring. Each limiting ring and limiting block are fixed by a pin. In use, the limiting ring is moved, causing the movable rod to move within the arc-shaped through hole, which in turn causes the adjusting plate to slide within the fan-shaped groove, ultimately adjusting to the required angle of the baffle. Then, the limiting ring is rotated to align the limiting ring and the limiting block, and finally fixed by the pin.

[0007] Option 3, which is a preferred option of the basic option, includes two sluices and two sliders. Each sluice is fixed to the mounting plate, each slider is detachably connected to the scraper, and each slider is slidably connected to the sluice. In use, the slider slides in the sluice, causing the scraper to move directionally on the baffle to remove rust and dust from the baffle.

[0008] Option 4, a preferred option of Option 3, features a detachable adjusting plate 3 on the slider. The adjusting plate 3 has a fan-shaped groove 2, within which the scraper slides. Several limiting blocks 2 are fixed to the adjusting plate 3, and a movable rod 2 is fixed to the scraper. An arc-shaped through hole 2 is also present on the adjusting plate 3, through which the movable rod 2 movably passes. A limiting ring 2 is rotatably connected to the free end of the movable rod 2. The limiting ring 2 and the limiting blocks 2 are fixed by a pin 2. In use, the limiting ring 2 is moved, causing the movable rod 2 to move within the arc-shaped through hole 2, allowing the scraper to slide within the fan-shaped groove 2. The scraper is adjusted to the same angle as the baffle. Then, the limiting ring 2 is rotated to align the limiting ring 2 and the limiting blocks 2. Finally, the scraper is fixed by the pin 2. This reduces the gap between the scraper and the baffle, increasing the effectiveness of removing rust and dust from the baffle.

[0009] Option 5, a preferred option of Option 4, features a T-shaped slider and groove, with each slider and adjusting plate 3 rotatably connected. When the scraper needs replacement, the slider is rotated so that the free end of the T-shaped slider is horizontal, allowing it to be removed from the T-shaped groove. After replacing the scraper, the horizontally positioned T-shaped slider is placed back into the T-shaped groove, and then rotated until its free end is vertical. Due to the weight of the scraper and adjusting plate 3, the T-shaped slider is secured within the T-shaped groove. This structure is simple and easy to operate, increasing the practicality of the device.

[0010] Option 6, an optimal choice from the basic option, features two bolt holes on each side of the baffle, a limit hole on each adjusting plate, and a strip-shaped through hole at each end of the baffle. The adjusting plate moves within the strip-shaped through hole, and a fixing bolt is threaded into each bolt hole, with the fixing bolt moving through the limit hole. When the baffle needs maintenance, the fixing bolt is removed from the bolt hole, and then the strip-shaped through hole and the adjusting plate are separated, facilitating baffle maintenance and increasing the baffle's service life.

Each of the two surfaces has two bolt holes 24, and the baffle 3 has strip-shaped through holes 17 at both ends. The adjusting plate 2 5 moves within the strip-shaped through holes 17. Each bolt hole 24 is threaded with a fixing bolt 12, which moves through the limiting hole 11. Each adjusting plate 4 is provided with a limiting component for fixing the adjusting plate 2 5. The limiting component includes two movable rods 18, two pins 10, two limiting rings 8, and several limiting blocks 9. Each movable rod 18 is fixedly connected to the adjusting plate 2 5, and each limiting block 9... The sliding block 19 and the adjusting plate 14 are fixedly connected. Each adjusting plate 14 has an arc-shaped through hole 16 on one side. Each movable rod 18 is rotatably connected to the limiting ring 8 by passing through the arc-shaped through hole 16. Each limiting ring 8 and the limiting block 9 are fixed by a pin 10. The scraper 7 is provided with a moving assembly for moving the scraper 7. The moving assembly includes two slide grooves 13 and two sliders 14. Each slider 14 and slide groove 13 is T-shaped. Each slider 14 and slide groove 13 are slidably connected. Each slide groove 13 and the mounting plate are connected to the mounting plate. 2. Fixed connection: Each slider 14 is rotatably connected to an adjusting plate 3 6.
