Description

Technical Field

[0001] This utility model relates to the field of composite steel plate technology, specifically to a hot rolling roll assembly for composite steel plates. Background Technology

[0002] Composite steel plates are layered structural plates made by combining metal materials with different properties through a specific process. Hot rolling roll assemblies are required in the processing of composite steel plates. Hot rolling rolls are important components and tools used for hot rolling steel. They are mainly used to shape and process heated steel billets through repeated rolling pressure and temperature changes. Their surface quality and performance directly affect the surface quality and dimensional accuracy of the steel.

[0003] During the rolling process, hot rolling rolls are prone to the adhesion of impurities on their surface due to residual iron oxide scale and mechanical friction. Cleaning these impurities requires cleaning the roll surface with a cleaning scraper. Traditional cleaning scrapers are a single unit, making it difficult to disassemble and maintain individual areas. Therefore, it is difficult to perform targeted local replacement based on the wear level of different locations, and the entire cleaning scraper needs to be replaced, which increases maintenance costs. Therefore, a hot rolling roll assembly made of composite steel plate is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a hot rolling roll assembly for composite steel plates, which can perform targeted local replacement of the cleaning scraper according to the wear degree of different positions, without the need to replace the entire cleaning scraper, thereby reducing maintenance costs and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hot-rolling roll assembly for composite steel plates includes supporting side plates arranged symmetrically on both sides. A pair of roll bodies are rotatably connected between the two supporting side plates. A sliding assembly is provided above the supporting side plates, and a cleaning assembly is provided below the sliding assembly. The sliding assembly includes a sliding support plate fixedly connected to the top of the supporting side plates. A sliding support rod is fixedly connected between the two sliding support plates. A sliding support seat is slidably connected to the outer side of the sliding support rod. A connecting support rod is fixedly connected to the bottom of the sliding support seat. The cleaning assembly includes a pair of cleaning rings sleeved on the outer side of the roll bodies. A plurality of cleaning scrapers are attached to the inner side of the cleaning rings. The bottom end of the connecting support rod is fixedly connected to the upper cleaning ring. The two cleaning rings are fixedly connected by a short rod.

[0007] As a further optimization of this utility model, the cleaning scraper is arc-shaped, the outer wall of the cleaning scraper matches the curvature of the inner wall of the cleaning ring, and the inner wall of the cleaning scraper matches the outer dimensions of the roller.

[0008] As a further optimization of this utility model, one end of the cleaning scraper is fixedly connected to a mounting plate, the end of the mounting plate away from the cleaning scraper is fixedly connected to a rubber clip, and the other end of the cleaning scraper is provided with a mounting slot, the mounting slot being configured to match the specifications of the mounting plate and the rubber clip.

[0009] As a further optimization of this utility model, both the mounting plate and the mounting slot are arc-shaped, and the curvature of both the mounting plate and the mounting slot is consistent with the curvature of the cleaning scraper.

[0010] As a further optimization of this utility model, one end of the cleaning scraper is fixedly connected to a mounting plate, and a mounting bolt passes through the center of the mounting plate.

[0011] As a further optimization of this utility model, one end of the cleaning ring is provided with a plurality of mounting screw holes, and the mounting screw holes and mounting bolts are set in equal numbers, corresponding in position and matching in specifications.

[0012] As a further optimization of this utility model, a pair of first magnetic blocks are symmetrically and fixedly connected to the outer side of the cleaning ring sleeve, and the outer side of the first magnetic blocks is flush with the left and right ends of the cleaning ring sleeve. A pair of second magnetic blocks are symmetrically and fixedly connected to the inner side of the support side plate, and the second magnetic blocks and the first magnetic blocks are positioned correspondingly and matched in specifications.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the sliding component provides the cleaning component with sliding displacement capability, allowing it to smoothly pass over the rollers. This enables the cleaning component to perform synchronous cleaning of a pair of rollers. Compared to the traditional method of cleaning different roller surfaces separately using external tools, this not only saves time and effort but also increases cleaning efficiency. Furthermore, the cleaning scraper is easy to disassemble and maintain independently, allowing for targeted local replacement based on the wear level of different locations, eliminating the need for complete scraper replacement and reducing maintenance costs. The disassembly and assembly of the cleaning scraper is also simple. The first and second magnetic blocks can magnetically limit the cleaning component when it is not cleaning, preventing it from affecting the normal operation of the rollers due to a lack of limiting capability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Please see Figure 1-6 This utility model provides a technical solution:

[0025] A hot-rolling roll assembly for composite steel plates includes a support side plate 1, which is symmetrically arranged on the left and right. A pair of roll bodies 2 are rotatably connected between the two support side plates 1. A sliding assembly 3 is provided above the support side plate 1, and a cleaning assembly 4 is provided below the sliding assembly 3. The sliding assembly 3 includes a sliding support plate 301 fixedly connected to the top of the support side plate 1. A sliding support rod 302 is fixedly connected between the two sliding support plates 301. A sliding support seat 303 is slidably connected to the outside of the sliding support rod 302. A connecting support rod 304 is fixedly connected to the bottom of the sliding support seat 303. The cleaning assembly 4 includes a pair of cleaning rings 401. The cleaning rings 401 are sleeved on the outside of the roll body 2. A plurality of cleaning scrapers 402 are attached to the inside of the cleaning rings 401. The bottom end of the connecting support rod 304 is fixedly connected to the cleaning rings 401 located above. The two cleaning rings 401 are fixedly connected by a short rod.

[0026] As a further implementation of this solution, the cleaning scraper 402 is arc-shaped, with the outer wall of the cleaning scraper 402 matching the curvature of the inner wall of the cleaning ring 401, and the inner wall of the cleaning scraper 402 matching the outer dimensions of the roller body 2. The arc-shaped design of the cleaning scraper 402 can better fit the inner wall of the cleaning ring 401 and the outer side of the roller body 2, thereby ensuring the stability of the cleaning scraper 402 and the cleaning effect.

[0027] As a further implementation of this solution, a mounting plate 403 is fixedly connected to one end of the cleaning scraper 402, and a rubber clip 404 is fixedly connected to the end of the mounting plate 403 away from the cleaning scraper 402. A mounting slot 405 is provided at the other end of the cleaning scraper 402. The mounting slot 405 is configured to match the specifications of the mounting plate 403 and the rubber clip 404. The cooperative use of the mounting plate 403, the rubber clip 404 and the mounting slot 405 can provide good combination capability between the cleaning scraper 402. Therefore, targeted local replacement can be carried out according to the wear degree of the cleaning scraper 402 in different positions, without the need to replace the entire cleaning scraper 402, thereby reducing maintenance costs.

[0028] As a further implementation of this solution, both the mounting plate 403 and the mounting slot 405 are arc-shaped. The curvature of the mounting plate 403 and the mounting slot 405 is consistent with the curvature of the cleaning scraper 402. The arc-shaped mounting plate 403 and the mounting slot 405 can make a more matching combination between the cleaning scrapers 402.

[0029] As a further implementation of this solution, a mounting plate 406 is fixedly connected to one end of the cleaning scraper 402, and a mounting bolt 407 passes through the center of the mounting plate 406. The mounting plate 406 and the mounting bolt 407 can provide an installation base between the cleaning scraper 402 and the cleaning ring 401.

[0030] As a further implementation of this solution, a number of mounting screw holes 408 are provided at one end of the cleaning ring 401. The mounting screw holes 408 and the mounting bolts 407 are set in equal numbers, corresponding positions and matching specifications. By screwing the mounting bolts 407 in the mounting support plate 406 into the mounting screw holes 408, a stable connection can be provided between the cleaning scraper 402 and the cleaning ring 401.

[0031] As a further implementation of this solution, a pair of first magnetic blocks 5 are symmetrically and fixedly connected to the outer side of the cleaning ring 401. The outer side of the first magnetic blocks 5 is flush with the left and right ends of the cleaning ring 401. A pair of second magnetic blocks 6 are symmetrically and fixedly connected to the inner side of the support side plate 1. The second magnetic blocks 6 and the first magnetic blocks 5 are positioned correspondingly and matched in specifications. The first magnetic blocks 5 and the second magnetic blocks 6 can limit the cleaning component 4 by magnetic attraction when the cleaning component 4 is not cleaning, so as to prevent the cleaning component 4 from affecting the normal operation of the roller 2 due to lack of limiting ability.

[0032] Workflow: When processing composite steel plates, the roller body 2 operates normally for rolling. When it is necessary to scrape and clean impurities from the surface of the roller body 2, the machine is first stopped. Then, the cleaning ring 401 is moved towards the roller body 2. The two cleaning rings 401 move synchronously. The cleaning ring 401 slides on the sliding support rod 302 between the sliding support plates 301 via the connecting support rod 304 and the sliding support 303, so that the cleaning ring 401 slides from one end of the roller body 2 to the other end. During this process, the cleaning scraper 402 in the cleaning ring 401 will contact the outer side of the roller body 2 and move... The cleaning rings 401, which move synchronously, scrape away impurities from the outer surface of the passing rollers 2. This method, compared to the traditional method of cleaning different roller surfaces separately using external tools, is not only more time-saving and labor-saving but also more efficient. Furthermore, the cleaning scrapers 402 can be independently disassembled and maintained, allowing for targeted replacement based on their wear levels, eliminating the need for complete replacement and reducing maintenance costs. The process is relatively simple. When assembling the cleaning scrapers 402, first insert the mounting plate 403 and rubber clip 404 at one end of one cleaning scraper 402 into the mounting slot 405 at one end of another cleaning scraper 402. The rubber clip 404 will deform due to compression when inserted into the mounting slot 405, and will return to its original shape after being fully inserted, thus locking the two cleaning scrapers 402 together. The remaining cleaning scrapers 402 can be assembled in the same way. The assembled cleaning scrapers 402 will form a complete ring. Pass the end of this ring without the mounting support plate 406 through the cleaning scraper. The ring 401 is used to hold the mounting plate 406 in place at one end of the cleaning ring 401. The ring is rotated and adjusted so that the holes of the mounting bolts 407 correspond to the positions of the mounting screw holes 408. Finally, the mounting bolts 407 are screwed into the mounting screw holes 408 one by one. The same principle applies to disassembly. When it is not necessary to scrape and clean the surface of the roller body 2, the cleaning component 4 is slid to the inside of the support side plate 1 on one side by the sliding component 3. The cleaning component 4 is limited by the magnetic attraction of the first magnetic block 5 and the second magnetic block 6 to prevent the cleaning component 4 from affecting the normal operation of the roller body 2 due to the lack of limiting ability.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
