[0002] As a pillar industry of the national economy, the steel industry has undergone long-term development and has gradually moved from traditional large-scale production to a modern stage of high-quality and high-efficiency development. Among the many stages of steel production, billet rolling is the core process connecting steelmaking and rolling. Its processing quality directly affects the performance and precision of subsequent products and has a key impact on the stability and economy of the entire steel production chain.

[0003] The existing steel rolling mill's billet cross-section increasing rolling guide device has poor synchronization of guide structure spacing adjustment during use, which easily leads to billet conveying deviation, and then causes hard friction between the billet and the guide components. This not only scratches the billet surface and affects the rolling quality, but also aggravates the wear of the guide components, shortens the service life of the equipment, and seriously affects the production efficiency of the steel rolling mill.

[0004] Therefore, a billet cross-section increasing rolling guide device for steel rolling collaboration is proposed to address the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] like Figures 1 to 5 As shown, this utility model provides a billet cross-section increasing rolling guide device for steel rolling cooperation, including a conveying component 1. The conveying component 1 consists of several conveying rollers 12 and two conveying frames 11. The conveying rollers 12 are driven by a motor to achieve synchronous rotation. Several guide components 2 are fixedly connected to the top of the two conveying frames 11.

[0030] The guiding assembly 2 includes a guide frame 21, which is fixedly connected to the conveyor frame 11. A cylinder 23 is fixedly connected to the top of the guide frame 21. The output end of the cylinder 23 passes through the guide frame 21 and is fixedly connected to a moving plate 25. Two inclined grooves 27 are opened at one end of the moving plate 25. The two inclined grooves 27 are mirror-distributed. A slider 242 is slidably connected to the inner surface of each of the two inclined grooves 27. A guide rod 24 is fixedly connected to one end of each of the two sliders 242. A gap is left between two adjacent conveyor rollers 12. The bottom end of the guide rod 24 extends into the gap between the two conveyor rollers 12. An installation groove 244 is opened at one end of the guide rod 24. The upper and lower inner walls of the installation groove 244 are rotatably connected to a guide roller 243. The cylinder 23 drives the moving plate 25 to drive the inclined grooves 27 and the sliders 242 to cooperate, so as to realize the synchronous reverse movement of the guide rod 24, accurately adjust the spacing of the guide rollers 243, adapt to different specifications of billets, solve the problem of billet offset caused by asynchronous adjustment of traditional guiding devices, and improve guiding stability.

[0031] Specifically, the outer surfaces of the conveyor roller 12 and the guide roller 243 are fixedly fitted with high-temperature resistant anti-slip sleeves. The high-temperature resistant anti-slip sleeves not only enhance the friction between the conveyor roller 12 and the billet, and between the guide roller 243 and the billet, preventing the billet from slipping in a high-temperature environment, but also resist the erosion of high-temperature rolling, reduce the direct friction damage between the billet and the roller body, and ensure the surface quality of the billet.

[0032] like Figures 1 to 5 As shown, guide grooves 28 are provided on both inner walls of the guide frame 21. Guide blocks 26 that cooperate with the guide grooves 28 are fixedly connected to both ends of the moving plate 25. The sliding cooperation between the guide blocks 26 and the guide grooves 28 restricts the lifting trajectory of the moving plate 25, prevents the moving plate 25 from deviating or shaking during the movement, ensures the stability of the cylinder 23 drive, and thus improves the adjustment accuracy of the guide rod 24.

[0033] Furthermore, the inner walls on both sides of the guide frame 21 are fixedly connected with crossbars 29. One end of the guide rod 24 has a through groove 241. The crossbar 29 is slidably connected to the guide rod 24 through the through groove 241. The cooperation between the crossbar 29 and the through groove 241 provides stable support and sliding guidance for the guide rod 24, preventing the guide rod 24 from bending and deforming during adjustment and operation, ensuring the constraint effect of the guide roller 243 on the blank, and improving the overall structural reliability of the device.

[0034] like Figures 1 to 5 As shown, both the through groove 241 and the crossbar 29 have rectangular cross sections, and the outer surface of the crossbar 29 is coated with a lubricating layer. The rectangular cross section of the through groove 241 and the crossbar 29 cooperate to prevent the guide rod 24 from rotating when sliding, ensuring the stability of the guide roller 243. The lubricating layer reduces the sliding friction between the through groove 241 and the crossbar 29, reduces wear, improves the smoothness of the guide rod 24 adjustment, and extends the service life of the equipment.

[0035] It is worth noting that the guide frame 21 includes a fixed rod 22 fixedly connected to the lower inner wall of the guide frame 21. The bottom end of the fixed rod 22 is provided with a receiving groove 221. A return spring 223 is fixedly connected to the upper inner wall of the receiving groove 221. A movable rod 225 is fixedly connected to the bottom end of the return spring 223. A cleaning plate 226 is fixedly connected to the bottom end of the movable rod 225 by bolts. A wire brush 227 is fixedly connected to the bottom end of the cleaning plate 226. The return spring 223 pushes the movable rod 225 to keep the wire brush 227 in contact with the top surface of the billet, and simultaneously removes dust and oxide scale debris from the surface of the billet, avoiding impurities from affecting the rolling accuracy. Moreover, no additional driving equipment is required, simplifying the structure and reducing energy consumption.

[0036] like Figures 1 to 5 As shown, two limiting grooves 224 are formed on the inner surface of the receiving groove 221. A limiting block 222 that works with the two limiting grooves 224 is fixedly connected to the outer surface of the movable rod 225. The sliding engagement between the limiting block 222 and the limiting groove 224 restricts the movement direction of the movable rod 225, preventing the movable rod 225 from shifting or rotating under the action of the return spring 223, ensuring the stability of the cleaning direction of the wire brush 227 and improving the cleaning effect.

[0037] It is worth emphasizing that the length of the cleaning plate 226 is adapted to the width of the billet conveying direction, and both the cleaning plate 226 and the wire brush 227 are made of high-temperature resistant materials. The length of the cleaning plate 226 is adapted to the width of the billet to ensure that there are no dead corners for cleaning on the top surface of the billet. The cleaning plate 226 and the wire brush 227, made of high-temperature resistant materials, can withstand the high temperature of the rolling environment and avoid deformation or damage due to high temperature, thus ensuring the long-term stable performance of the cleaning function.

[0038] Working principle and process: During use, the motor drives the conveyor roller 12 to rotate synchronously, moving the billet along the conveying direction; according to the billet specifications, the cylinder 23 drives the moving plate 25 to rise and fall, and the moving plate 25 drives the slider 242 to slide through the mirror-distributed inclined groove 27, thereby causing the guide rod 24 to move synchronously in the opposite direction along the through groove 241 of the crossbar 29, adjusting the spacing of the guide rollers 243 to a suitable billet size; during the billet movement, the guide rollers 243 constrain the billet to shift laterally through rolling contact, while the reset spring 223 below the fixed rod 22 pushes the movable rod 225, causing the wire brush 227 to adhere to the top surface of the billet, synchronously removing surface impurities; the guide blocks 26 at both ends of the moving plate 25 slide along the guide groove 28, and the limiting block 222 on the movable rod 225 slides along the limiting groove 224, ensuring stable movement of each component, ultimately achieving precise guidance and cleaning of the billet, and ensuring the quality of the cross-section rolling.
