Description

Technical Field

[0001] This utility model relates to the field of steel rolling technology, specifically to a guide ruler for a hot rolling coiler. Background Technology

[0002] The guide rail of a hot rolling coiler is an essential device on a hot rolling mill. Its main function is to align the strip steel with the rolling centerline and feed it into the pinch rolls. As the strip enters the pinch rolls, the guide rail clamps it to reduce the tapering of the coil and ensure the strip is correctly and smoothly guided into the coiler. By adjusting the opening of the guide plates on both sides, the alignment of strip steel of different widths and specifications with the coiler can be controlled, thereby ensuring the quality of the strip coiling.

[0003] The patent with publication number CN216801167U discloses a guide ruler for a hot-rolled coiler, which relates to the field of steel rolling technology. It includes a long, narrow guide ruler body with a steel inlet on one side and a steel outlet on the other. Multiple arc-shaped openings are evenly distributed on the bottom surface of the guide ruler body, and multiple bolt holes are evenly distributed on the vertical sidewalls of the guide ruler body. Through-holes, with identical specifications, are provided on the guide ruler body, penetrating the sidewalls and located between every two arc-shaped openings. This invention utilizes alloy powder welded onto a common steel plate to form a wear-resistant block. Through-holes are then created on the guide ruler, and the wear-resistant block is snapped into the through-hole and fixed with screws. This reduces deformation of the guide ruler during installation, improves the yield rate, and allows for double-sided use, increasing its utilization rate. The wear-resistant block is removable and can be replaced without replacing the guide ruler body, extending the guide ruler's service life and saving costs.

[0004] Although the above-mentioned device extends the service life of the guide ruler by incorporating removable wear-resistant blocks, it still has the following shortcomings:

[0005] During the hot rolling process, the friction between the guide and the hot-rolled material generates a large amount of heat and wear. Therefore, cooling water is often used for cooling and lubrication. However, the surface of the rolls and guides will develop an oxide layer due to long-term contact with the cooling water. This is the main cause of abnormal wear on the rolls and guides. We need to lubricate the guides and the hot-rolled material to extend the service life of the rolls and guides. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a guide ruler for a hot rolling coiler, which incorporates a lubrication component to reduce the coefficient of friction between the guide ruler and the hot-rolled material, thereby extending the service life of both the rolls and the guide ruler.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a guide ruler for a hot rolling coiler, comprising a guide ruler body symmetrically arranged at the top and bottom, a liner plate evenly arranged on the inner side of the guide ruler body, clamping components arranged on both sides of the guide ruler body, fixing plates arranged on both sides of the bottom surface of the guide ruler body at the lower end, a lubrication component arranged at the front end of the guide ruler body, the lubrication component comprising a lubrication box that runs through the front and rear, an oil spray plate symmetrically arranged at the top and bottom inside the lubrication box, an atomizing nozzle arranged on the oil spray plate, a lubricating oil tank arranged on one side of the lubrication box, an oil inlet pump arranged on the lubricating oil tank, and the oil spray plate connected to the oil inlet pump through an oil delivery pipe.

[0008] Furthermore, the lubrication box has oil brushes symmetrically arranged above and below the spray plate. An oil drain groove is opened on the bottom surface of the lubrication box at the position of the oil brush. A waste oil tank is set on the other side of the lubrication box. An oil pump is installed on the waste oil tank. An oil drain pipe is installed on one side of the waste oil tank. The oil pump is connected to the oil drain groove through the oil drain pipe.

[0009] Furthermore, the clamping assembly includes a movable block disposed on the side of the upper guide ruler body, the movable block being rotatably connected to a lead screw, the upper end of the lead screw being connected to a drive motor, a motor frame connected to the ground being disposed outside the drive motor, and the lower end of the lead screw being rotatably connected to a fixed plate.

[0010] Furthermore, position detectors are symmetrically arranged on both sides of the guide ruler body between the clamping components.

[0011] Furthermore, heat dissipation cavities are provided on both sides of the guide ruler body.

[0012] Furthermore, the lubrication box is symmetrically equipped with feed rollers above and below the oil spray plate.

[0013] Furthermore, a connecting block is provided in the middle of the top surface of the liner plate, and the guide ruler body has a connecting groove that fits with the connecting block. The guide ruler body and the connecting block are connected by bolts.

[0014] Furthermore, the liner is arranged in a parallelogram shape, the front end of the guide ruler body is provided with a guide plate that fits the liner, and the lubrication box is provided with a guide groove that fits the guide plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By installing a lubrication component in front of the guide ruler, the hot-rolled material is evenly sprayed with lubricating oil before entering the guide ruler, reducing the coefficient of friction between the guide ruler and the liner, thereby extending the service life of the liner and the guide ruler, and also preventing the hot-rolled material from being worn in the guide ruler; by symmetrically installing oil brushes above and below the oil spray plate, not only can the lubricating oil on the hot-rolled material be evenly spread, but excess lubricating oil can also be brushed off. This waste oil will fall into the oil drain tank and enter the waste oil tank through the oil extraction pipe and oil pump. After being processed by the staff, it will be added back into the lubricating oil tank, reducing the loss of lubricating oil and improving the resource utilization rate.

[0017] 2. By setting clamping components on both sides of the guide ruler, the opening and closing degree of the guide ruler can be adjusted by the clamping components, which can adapt to the alignment of strip steel of different widths and specifications with the coiler, thus expanding the scope of application; by setting a through heat dissipation cavity, the heat dissipation efficiency of the guide ruler is improved, preventing the guide ruler from being damaged due to overheating; by setting a position detector, the distance between the upper and lower guide rulers is monitored in real time, ensuring that the guide ruler body operates in the correct position, thus enhancing the safety and reliability of the equipment.

[0025] 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.

[0026] like Figures 1 to 6 As shown, a guide ruler for a hot rolling coiler includes a guide ruler body 1 symmetrically arranged vertically. A liner plate 2 is evenly arranged on the inner side of the guide ruler body 1. Clamping components 3 are arranged on both sides of the guide ruler body 1. Fixing plates 4 are arranged on both sides of the bottom surface of the guide ruler body 1 at the lower end. A lubrication component 5 is arranged at the front end of the guide ruler body 1. The lubrication component 5 includes a lubrication box 501 that runs through the front and rear. Oil spray plates 502 are symmetrically arranged vertically inside the lubrication box 501. Atomizing nozzles 503 are arranged on the oil spray plates 502. A lubricating oil tank 504 is arranged on one side of the lubrication box 501. An oil inlet pump 505 is arranged on the lubricating oil tank 504. The oil spray plates 502 are connected to the oil inlet pump 505 through an oil delivery pipe 506.

[0027] like Figure 1 As shown, the hot-rolled coiler guide ruler in this utility model is similar in structure to existing hot-rolled coiler guide rulers, such as the hot-rolled coiler guide ruler disclosed in patent publication number CN216801167U. The main improvement of this utility model is that it sets a lubrication component to reduce the coefficient of friction between the guide ruler and the hot-rolled material, such as... Figures 1 to 6As shown, in this utility model, the guide ruler of the hot rolling coiler is adjusted according to the width and specifications of the strip steel. The drive motor 303 is then controlled to rotate the lead screw 302, thereby driving the moving block 301 and the guide ruler body 1 to move up and down. After moving to the appropriate position, the hot-rolled material will enter the lubrication box 501 with the assistance of the feed roller 512. Subsequently, with the cooperation of the oil pump 505 and the oil delivery pipe 506, the lubricating oil will be sent to the spray plate 502 and then sprayed by the atomizing nozzle 503 on the spray plate 502. The process involves atomizing the hot-rolled material and spraying it onto both the top and bottom surfaces to achieve initial lubrication. The hot-rolled material then advances, and as it passes the oil brush 507, the brush evenly coats both surfaces with lubricating oil while brushing off excess oil. This waste oil falls into the oil drain trough 508 and enters the waste oil tank 509 via the oil extraction pipe 511 and the oil pump 510. The lubricated hot-rolled material exits from the lubrication tank 501 and enters the guide plate 103 into the guide ruler body 1, where it is then clamped by the liner plate 2 to reduce the tower shape of the steel coil.

[0028] like Figure 1 As shown, the lubrication box 501 has oil brushes 507 symmetrically arranged above and below the oil spray plate 502. The bottom surface inside the lubrication box 501 has an oil drain groove 508 at the position of the oil brushes 507. The other side of the lubrication box 501 has a waste oil tank 509. The waste oil tank 509 is equipped with an oil pump 510. The oil drain groove 508 has an oil suction pipe 511 on one side of the waste oil tank 509. The oil pump 510 is connected to the oil drain groove 508 through the oil suction pipe 511.

[0029] Specifically, by symmetrically setting oil brushes 507 above and below the spray plate 502, not only can the lubricating oil on the hot-rolled material be evenly applied, but excess lubricating oil can also be brushed off. This waste oil will fall into the drain trough 508 and enter the waste oil tank 509 through the oil extraction pipe 511 and the oil pump 510. After being processed by the staff, it will be added back into the lubricating oil tank 504, reducing the loss of lubricating oil and improving the resource utilization rate.

[0030] like Figure 2 and Figure 3 As shown, the clamping assembly 3 includes a movable block 301 disposed on the side of the upper guide ruler body 1. The movable block 301 is rotatably connected to a lead screw 302. The upper end of the lead screw 302 is connected to a drive motor 303. The drive motor 303 is provided with a motor frame 304 connected to the ground. The lower end of the lead screw 302 is rotatably connected to a fixed plate 4.

[0031] Specifically, driven by the drive motor 303, the lead screw 302 rotates to drive the moving block 301 to move up and down, thereby controlling the guide ruler body 1 located at the upper end and adjusting the opening and closing degree between the guide ruler bodies 1, so as to adapt to strip steel of different widths and specifications, and expand the application range of the guide ruler.

[0032] like Figure 1 and Figure 2 As shown, position detectors 6 are symmetrically arranged on both sides of the guide ruler body 1 between the clamping components 3. This arrangement can monitor the distance between the upper and lower guide rulers in real time, ensuring that the guide ruler body 1 is operated in the correct position, thereby enhancing the safety and reliability of the equipment.

[0033] like Figure 2 As shown, the guide ruler body 1 has through heat dissipation cavities 101 on both sides. This design can improve the heat dissipation efficiency of the guide ruler body 1 and prevent the guide ruler body 1 from being damaged due to overheating.

[0034] like Figure 5 and Figure 6 As shown, the lubrication box 501 is symmetrically equipped with feed rollers 512 in front of the oil spray plate 502. This arrangement makes it convenient for workers to guide hot-rolled materials into the lubrication box 501.

[0035] like Figure 2 and Figure 4 As shown, a connecting block 201 is provided in the middle of the top surface of the liner plate 2, and a connecting groove 102 that fits with the connecting block 201 is provided on the guide ruler body 1. The guide ruler body 1 and the connecting block 201 are connected by bolts. The liner plate 2 is arranged in a parallelogram shape. A guide plate 103 that fits with the liner plate 2 is provided at the front end of the guide ruler body 1. A guide groove 513 that fits with the guide plate 103 is provided in the lubrication box 501.

[0036] Specifically, by setting the connecting block 201, we can connect the liner plate 2 and the guide ruler body 1 with bolts, which makes it convenient for the staff to replace the liner plate 2. The parallelogram-shaped liner plate 2 allows the liner plate 2 to be installed in sequence to avoid misalignment. The guide plate 103 is set at the front end of the guide ruler body 1, which can cooperate with the liner plate 2 to introduce the hot-rolled material onto the liner plate 2. At the same time, it cooperates with the guide groove 513 to guide the lubrication box 501, so that the two are tightly fitted together.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
