[0002] With the progress of the times and the continuous development of technology, steel is being industrialized in various ways and then reprocessed before being sold. When it is necessary to press steel to the required thickness, rolling mills are used to process the steel. In order to meet different needs during processing, it is particularly important to propose a fixed beam fine-tuning mechanism for 18-roll rolling mills.

[0003] Chinese Utility Model Patent Application No. CN218873265U discloses a novel adjusting and fixing device for the inlet crossbeam of a rolling mill, relating to the field of inlet crossbeams of rolling mills. The device includes a rolling mill body and an inlet crossbeam. A sliding groove is provided on the front side wall of the rolling mill body, and a slider is slidably installed within the groove. The inlet crossbeam is located on the front side of the slider, and a threaded groove is provided inside the slider, with a threaded rod threadedly installed within the groove. This utility model supports the slider via the threaded rod, thereby supporting the inlet crossbeam and ensuring its stability. The inlet crossbeam can be adjusted by rotating the threaded rod, which is convenient. Furthermore, the device can be adjusted online during operation to ensure the alignment of the inlet crossbeam with the rolling line, thereby reducing the occurrence of steel pile-up accidents.

[0004] While the aforementioned mill inlet crossbeam adjustment and fixing device is convenient for ensuring steel output and reducing steel pile-up accidents, it still has the following defects in actual use: 1. When the pressed steel plate is output, it cannot be limited and supported, making it easy for the steel plate to shift and cause steel pile-up when it is rolled and output; 2. The square cone corner of the crossbeam opening is prone to scratching the surface of the steel plate when it is output, affecting the quality of the steel plate. Summary of the Invention

[0005] The purpose of this utility model is to address the problems of the lack of a limiting component for the output of the pressed steel plate, which makes the steel plate prone to deviation and steel piling when it is rolled out, and the square cone angle of the crossbeam opening easily scratching the surface of the steel during steel production, affecting the quality of the steel.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fixed beam fine-tuning mechanism for an 18-roll rolling mill includes an 18-roll rolling mill body, a lifting groove formed on one side of the 18-roll rolling mill body, and a lifting plate disposed on one side of the 18-roll rolling mill body, and further includes:

[0008] The limiting structure includes a first connecting slide plate disposed on one side of the lifting groove, a second connecting slide plate fixed to the inner side wall of the first connecting slide plate, a connecting frame fixed to the bottom end of the second connecting slide plate, a connecting rod rotatably connected inside the connecting frame, a limiting rotating column fixed to the outer side wall of the connecting rod, a slide rod disposed on one side of the second connecting slide plate, a driving rotating rod disposed on one side of the first connecting slide plate, and a driving motor installed at one end of the driving rotating rod.

[0009] A guide structure is provided inside the lifting plate to support and guide the steel plate output from the 18-roll mill.

[0010] In a preferred embodiment of the present invention, the lifting groove is provided with a lifting structure, which includes a lifting motor installed at the bottom of the 18-roll mill body, a lifting shaft installed at the output end of the lifting motor, and lifting blocks fixed on both sides of the lifting plate.

[0011] In a preferred embodiment of this utility model, the outer wall of the lifting shaft is uniformly provided with external threads, the interior of the lifting block is uniformly provided with internal threads, and the lifting shaft and the lifting block are threadedly connected.

[0012] In a preferred embodiment of the present invention, the guide structure includes a bottom groove fixed to the bottom end of the inner sidewall of the lifting plate, a guide plate disposed at the top end of the bottom groove, a connecting shaft passing through the inside of the guide plate, and mounting nuts threaded to both ends of the connecting shaft.

[0013] In a preferred embodiment of the present invention, an arc-shaped groove is provided at the top of the bottom groove, a cylindrical fixing block is fixed at the bottom of the guide plate, and the two ends of the connecting shaft pass through the two ends of the bottom groove and extend to the outside of the lifting plate.

[0014] In a preferred embodiment of this utility model, a cleaning structure is provided on one side of the lifting plate. The cleaning structure includes an extension rod fixed to the outer wall of the lifting plate, an electric telescopic mechanism fixed to the outer side of the bottom end of the extension rod, a connecting block fixed to the bottom end of the electric telescopic mechanism, a cleaning shaft installed on the inner wall of the connecting block, a cleaning brush installed on the outer wall of the cleaning shaft, and a cleaning motor installed on one end of the cleaning brush.

[0015] In a preferred embodiment of this utility model, the extension rod and the electric telescopic machine are symmetrically arranged on both sides of the lifting plate, and the connecting block and the cleaning shaft are rotatably connected.

[0016] In a preferred embodiment of this utility model, the connecting rotating rod and the limiting rotating post are arranged at equal intervals inside the connecting frame, and the outer wall of the driving rotating rod is provided with external threads in opposite directions.

[0017] This invention solves the problems in the prior art where the steel plate lacks a limiting component upon exiting the rolling mill, leading to steel plate shifting and piling during output, and where the square cone angle of the crossbeam opening easily scratches the steel plate surface during production, affecting steel quality.

[0018] 1. This utility model provides a fixed beam fine-tuning mechanism for an 18-roll mill. By setting a limiting structure, including a connecting frame, a connecting rotating rod, and a limiting rotating column, the limiting rotating column rotates outside the connecting rotating rod to limit the steel during steel output, assisting in the direction of the steel plate. This allows the mill to limit the output of the rolled steel plate, thereby enabling more precise output and reducing the possibility of steel pile-up accidents.

[0019] 2. This utility model provides a fixed beam fine-tuning mechanism for an 18-roll mill. By setting a guide structure, the guide plate is installed on the bottom groove by connecting the rotating shaft and the mounting nut, so that the bottom groove can support the passing steel, allowing the mill to make smoother contact with the bottom surface of the steel plate when facing the limited output steel plate, reducing wear on the surface of the steel plate.

[0020] 3. This utility model provides a fixed beam fine-adjustment mechanism for an 18-roll mill. By setting a cleaning structure, an electric telescopic motor, a connecting block, a cleaning shaft, and a cleaning motor cooperate with each other to adjust the distance between the cleaning brushes. This allows the mill to clean the steel surface according to different thicknesses when the steel is being tapped, making subsequent coiling more convenient. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a fixed beam fine-tuning mechanism for an 18-roll mill includes an 18-roll mill body 1, a lifting groove 3 opened on one side of the 18-roll mill body 1, and a lifting plate 4 disposed on one side of the 18-roll mill body 1. It also includes a limiting structure 7, which includes a first connecting slide plate 701 disposed on one side of the lifting groove 3, a second connecting slide plate 702 fixed to the inner side wall of the first connecting slide plate 701, a connecting frame 703 fixed to the bottom end of the second connecting slide plate 702, a connecting rod 704 rotatably connected inside the connecting frame 703, a limiting rotating column 705 fixed to the outer side wall of the connecting rod 704, a slide rod 706 disposed on one side of the second connecting slide plate 702, a driving rotating rod 707 disposed on one side of the first connecting slide plate 701, and a driving motor 708 installed at one end of the driving rotating rod 707. The connecting rod 704 and the limiting rotating column 705 are evenly distributed inside the connecting frame 703, and the outer side wall of the driving rotating rod 707 is provided with external threads in opposite directions.

[0030] It should be noted that when the steel plate is pressed and output, a limiting structure 7, a connecting frame 703, a connecting rotating rod 704, and a limiting rotating column 705 are set up. When the steel is discharged, the limiting rotating column 705 rotates outside the connecting rotating rod 704 to limit the steel and assist the steel's direction. When facing steel plates of different widths, the drive motor 708 is started to drive the drive rotating rod 707 to rotate. At this time, the second connecting slide plates 702 at both ends of the drive rotating rod 707 can move in the same direction to adjust the distance. This allows the rolling mill to be limited when the steel plate is rolled out, enabling more accurate transmission and reducing the possibility of steel piling accidents.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the guide structure 5 is further disposed inside the lifting plate 4 to support and guide the steel plate produced by the 18-roll mill body 1. The guide structure 5 includes a bottom groove 501 fixed to the bottom end of the inner wall of the lifting plate 4, a guide plate 502 disposed at the top end of the bottom groove 501, a connecting shaft 503 passing through the inside of the guide plate 502, and mounting nuts 504 threaded to both ends of the connecting shaft 503. The top end of the bottom groove 501 is provided with an arc-shaped groove, and a cylindrical fixing block is fixed at the bottom end of the guide plate 502. The two ends of the connecting shaft 503 pass through the two ends of the bottom groove 501 and extend to the outside of the lifting plate 4.

[0032] It should be noted that by setting the guide structure 5, the guide plate 502 is installed on the bottom groove 501 by connecting the rotating shaft 503 and the mounting nut 504, so that the bottom groove 501 can support the passing steel. The top of the guide plate 502 is arc-shaped, which can reduce the direct contact surface with the steel and is less likely to damage the surface of the steel plate. This allows the rolling mill to make smoother contact with the bottom surface of the steel when facing the steel that has been limited, reducing wear on the steel surface and improving the pressing quality of the steel plate.

[0033] like Figure 1 , Figure 2 and Figure 5As shown, in a preferred embodiment, based on the above method, a lifting structure 2 is further provided inside the lifting groove 3. The lifting structure 2 includes a lifting motor 201 installed at the bottom of the 18-roll mill body 1, a lifting shaft 202 installed at the output end of the lifting motor 201, and lifting blocks 203 fixed to both sides of the lifting plate 4. The outer wall of the lifting shaft 202 is uniformly provided with external threads, and the interior of the lifting blocks 203 is uniformly provided with internal threads. The lifting shaft 202 and the lifting blocks 203 are threadedly connected. A cleaning device is provided on one side of the lifting plate 4. Structure 6, the cleaning structure 6 includes an extension rod 601 fixed to the outer wall of the lifting plate 4, an electric telescopic mechanism 602 fixed to the outer side of the bottom end of the extension rod 601, a connecting block 603 fixed to the bottom end of the electric telescopic mechanism 602, a cleaning shaft 604 installed on the inner wall of the connecting block 603, a cleaning brush 605 installed on the outer wall of the cleaning shaft 604, and a cleaning motor 606 installed at one end of the cleaning brush 605. The extension rod 601 and the electric telescopic mechanism 602 are symmetrically arranged on both sides of the lifting plate 4, and the connecting block 603 and the cleaning shaft 604 are rotatably connected.

[0034] It should be noted that by setting up the cleaning structure 6, the electric telescopic machine 602, the connecting block 603, the cleaning shaft 604 and the cleaning motor 606 cooperate with each other to adjust the distance between the cleaning brushes 605 so that the brush surface of the cleaning brushes 605 can contact the steel surface. Starting the cleaning motor 606 will cause the cleaning shaft 604 and the cleaning brushes 605 to rotate and start cleaning. This allows the rolling mill to clean the steel surface according to different thicknesses when the steel is exiting, making the subsequent coiling process more convenient.

[0035] In use, this invention utilizes the connecting frame 703, connecting rod 704, and limiting rotating column 705. During steel tapping, the limiting rotating column 705 rotates outside the connecting rod 704 to limit the steel's movement and assist in its trajectory. When dealing with steel of varying widths, the drive motor 708 is activated to rotate the drive rod 707. At this time, the second connecting slide plates 702 at both ends of the drive rod 707 can move in the same direction, adjusting the distance and reducing the possibility of steel stacking accidents. The guide plate 502 is installed on the bottom receiving groove 501 via the connecting shaft 503 and mounting nut 504, allowing the bottom receiving groove 501 to support the passing steel. The top of the plate 502 is arc-shaped, which allows the rolling mill to make smoother contact with the bottom surface of the steel when facing the steel that has been stopped, reducing wear on the steel surface. The electric telescopic mechanism 602, the connecting block 603, the cleaning shaft 604, and the cleaning motor 606 work together to adjust the distance between the cleaning brushes 605, so that the brush surface of the cleaning brushes 605 can contact the steel surface. Starting the cleaning motor 606 will cause the cleaning shaft 604 and the cleaning brushes 605 to rotate and begin cleaning. This allows the fixed beam fine-tuning mechanism of the 18-roll rolling mill to clean the steel surface according to different thicknesses when the steel is exiting, making subsequent coiling more convenient.

[0036] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
