Description

Technical Field

[0001] This utility model relates to the field of steel coil processing technology, specifically a hot rolling device for steel coils. Background Technology

[0002] Hot rolling is the opposite of cold rolling. Cold rolling is rolling performed below the recrystallization temperature, while hot rolling is rolling performed above the recrystallization temperature. Simply put, a steel billet is heated and rolled several times, then trimmed and straightened to become a steel plate. This is called hot rolling. Existing hot rolling equipment for steel coils can basically meet daily usage needs, but there are still some shortcomings that need to be improved.

[0003] Most of the hot rolling equipment for steel coils widely used in the market first place the steel billet into the heating chamber for heating, and then roll and trim the edges of the heated steel billet through a rolling mill. However, in actual use, burrs and impurities are easily left on the surface of the steel billet. If these impurities are not cleaned in time, they will be incorporated into the interior of the steel plate during the heating process, thus affecting the quality of the steel coil.

[0004] Patent CN221109356U discloses a hot rolling device for steel coils, including a heating chamber and a rolling mill installed behind the heating chamber. A placement platform is installed below the front end of the heating chamber. Two sets of fixed seats are fixed to the outer wall of the front end of the heating chamber, and a threaded rod is rotatably connected between the two sets of fixed seats. A turntable is fixed to the top of the threaded rod, and a movable block is threadedly connected to the outside of the threaded rod. Guide slides are installed on both sides of the threaded rod. By installing a movable block that can move up and down outside the heating chamber, rotating the turntable allows the threaded rod to rotate between the two sets of fixed seats. The movable block, under the action of the thread, drives a horizontal scraper to adjust its position along the guide slides, allowing the horizontal scraper to move to the surface of steel billets of different thicknesses. This scrapes away impurities or burrs from the surface of the steel billet before it enters the heating chamber, preventing impurities from melting into the interior of the steel billet and effectively preventing a decline in the quality of the steel coil.

[0005] However, the impurity removal structure in the above technology can only scrape off impurities or burrs on the upper surface of the steel billet. Impurities or burrs may also exist on the lower surface of the steel billet. If they are not removed, they will still affect the quality of the steel coil. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a hot rolling device for steel coils, which enables the simultaneous scraping of impurities or burrs from the upper and lower surfaces of the steel billet.

[0008] Preferably, the first scraping assembly includes a strip block slidably connected between two slide rods, the bottom of the strip block has a groove, a convex block matching the groove is connected in the groove, and a first scraper is connected to the end of the convex block away from the groove.

[0009] Preferably, the limiting component includes a mounting block connected above the middle strip block at the front end of the heating chamber. The mounting block has a vertical first threaded hole. A half-hole-shaped connecting block is fixedly connected to the top of the strip block. A through hole is opened at the top of the connecting block. A lead screw passing through the first threaded hole and the through hole is connected between the mounting block and the connecting block. A turntable is connected to the top of the lead screw, and a fixing block is connected to the bottom of the lead screw. The thread of the lead screw meshes with the thread of the first threaded hole.

[0010] Preferably, the second scraping assembly includes a convex snap-fit ​​block connected in the snap-fit ​​groove, and a second scraper is connected to one end of the convex snap-fit ​​block away from the snap-fit ​​groove.

[0011] Preferably, a second threaded hole communicating with the outside is provided on the side of the first threaded hole away from the placement platform, and a threaded rod matching the second threaded hole is connected to the second threaded hole, with a rotating ring connected to the end of the threaded rod away from the second threaded hole.

Detailed Implementation

[0023] 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.

[0024] like Figure 1 and Figure 2As shown, a hot rolling device for steel coils includes a heating chamber 1, a placement platform 2 installed below the front end of the heating chamber 1, connecting blocks 3 connected to both sides of the front end of the heating chamber 1, a sliding rod 4 connected between the connecting blocks 3 and the placement platform 2 below them, a first scraping component 5 movably connected between the two sliding rods 4, a limiting component 6 for restricting the movement of the first scraping component 5 provided in the middle of the front end of the heating chamber 1, and a snap-fit ​​groove 7 opened on the top of the placement platform 2 near the heating chamber 1, and a second scraping component 8 connected to the snap-fit ​​groove 7.

[0025] Specifically, by setting a first scraping component 5 that is movably connected to the slide bar 4, the debris or burrs on the upper surface of the steel billet can be scraped off. At the same time, the position of the first scraping component 5 can be adjusted to adapt to steel billets of different thicknesses. After the position of the first scraping component 5 is determined, the first scraping component 5 is limited to the required position by using the limiting component 6 for subsequent use. Meanwhile, by setting a second scraping component 8, the debris or burrs on the lower surface of the steel billet can be scraped off. In this way, the debris or burrs on the upper and lower surfaces of the steel billet can be scraped off at the same time.

[0026] like Figure 3 As shown, the first scraping assembly 5 includes a strip block 9 slidably connected between two slide rods 4. A groove 10 is provided at the bottom of the strip block 9. A convex block 11 matching the groove 10 is connected in the groove 10. A first scraper 12 is connected to the end of the convex block 11 away from the groove 10.

[0027] Specifically, the first scraper 12 can scrape away debris or burrs on the upper surface of the steel billet. By setting the groove 10 and the convex block 11, when the first scraper 12 is damaged, pushing the convex block 11 can push the convex block 11 and the first scraper 12 out of the groove 10 together, which facilitates the replacement of the convex block 11 and the first scraper 12.

[0028] like Figure 2 and Figure 4 As shown, the limiting component 6 includes a mounting block 13 connected above the middle strip block 9 at the front end of the heating chamber 1. The mounting block 13 has a vertical first threaded hole 14. A half-mouth-shaped connecting block 15 is fixedly connected to the top of the strip block 9. A through hole 16 is opened at the top of the connecting block 15. A lead screw 17 passing through the first threaded hole 14 and the through hole 16 is connected between the mounting block 13 and the connecting block 15. A turntable 18 is connected to the top of the lead screw 17. A fixing block 19 is connected to the bottom of the lead screw 17. The thread of the lead screw 17 meshes with the thread of the first threaded hole 14.

[0029] Specifically, when in use, the turntable 18 is rotated. The rotation of the turntable 18 will cause the lead screw 17 and the fixing block 19 to move up or down. By changing the position of the fixing block 19, the position of the first scraping component 5 can be adjusted and the first scraping component 5 can be limited to the required position.

[0030] like Figure 5 As shown, the second scraping assembly 8 includes a convex snap-fit ​​block 20 connected in the snap-fit ​​groove 7, and a second scraper 21 is connected to one end of the convex snap-fit ​​block 20 away from the snap-fit ​​groove 7.

[0031] Specifically, the second scraper 21 can scrape away debris or burrs on the lower surface of the steel billet. By setting the snap-fit ​​groove 7 and the convex snap-fit ​​block 20, when the second scraper 21 is damaged, pushing the convex snap-fit ​​block 20 can push the convex snap-fit ​​block 20 and the second scraper 21 out of the snap-fit ​​groove 7 together, which facilitates the replacement of the convex snap-fit ​​block 20 and the second scraper 21.

[0032] like Figure 2 and Figure 4 As shown, a second threaded hole 22 communicating with the outside is provided on the side of the first threaded hole 14 away from the placement platform 2. A threaded rod 23 matching the second threaded hole 22 is connected to the second threaded hole 22. A rotating ring 24 is connected to the end of the threaded rod 23 away from the second threaded hole 22.

[0033] Specifically, by setting the second threaded hole 22 and the threaded rod 23, the lead screw 17 can be prevented from rotating in the mounting block 13, thereby making the limiting component 6 more firmly limiting the first scraping component 5. The rotating ring 24 can facilitate the rotation of the threaded rod 23.

[0034] like Figure 4 As shown, the turntable 18 has a first anti-slip texture 25.

[0035] Specifically, by setting the first anti-slip texture 25, the friction between the hand and the turntable 18 can be increased, thus making it easier for the staff to rotate the turntable 18.

[0036] like Figure 4 As shown, the rotating ring 24 has a second anti-slip texture 26.

[0037] Specifically, by setting a second anti-slip texture 26, the friction between the hand and the rotating ring 24 can be increased, making it easier for the staff to rotate the rotating ring 24.

[0038] 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.
