Description

Technical Field

[0001] This invention relates to the technical field of a straightening machine, and more particularly to a straightening machine roller system with a waterproof structure. Background Technology

[0002] Medium and heavy plate hot straightening machines are a type of steel plate finishing equipment, mainly used to correct shape defects in plastically processed steel plates. During the rolling process, steel plates may produce defects such as bending, wavy lines, and warping. Through the straightening process of the straightening machine, these defects can be eliminated under external force, bringing the product to a qualified state.

[0003] The straightening process of steel plates mainly involves repeatedly bending the strip with rollers to release stress and induce plastic deformation, thereby eliminating defects. The temperature of steel plates straightened by a hot straightener for medium and heavy plates is generally between 650 and 1000℃. In addition to internal cooling water within the roller system, external cooling water is also required. After the external cooling water cools the roller system, it is guided into the slag-removing groove through the guide structure on the roller seat.

[0004] Because the side rollers need to move up and down, the requirements for waterproofing are relatively high. Currently, the waterproofing of the side rollers in medium and heavy plate roller systems does not meet the requirements. After a period of use, when the roller system is repaired and adjusted, and when the external cooling water is stopped, the side roller lifting structure will rust. Furthermore, if the protection is inadequate, iron oxide scale from the steel plate can also enter the lifting structure, causing the side roller lifting to jam, which seriously affects the straightening effect. Therefore, it is necessary to improve this technology. Summary of the Invention

[0005] This invention provides a straightener roller system with a waterproof structure to ensure the normal operation of the straightener roller lifting mechanism.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a straightening machine roller system with a waterproof structure, comprising a lower roller box, a side roller seat installed in the lower roller box, a support roller assembly disposed in the lower roller box and fixed on the side roller seat, a side roller disposed on the support roller assembly, a top holding structure disposed in the lower roller box, and elastic support members disposed at both ends of the side roller. A waterproof structure is disposed between the top holding structure and the side roller seat. The waterproof structure includes a water-blocking assembly disposed at the lower part of the side roller seat and the upper part of the support plate, and a waterproof cylinder assembly disposed around the perforation of the support plate.

[0007] As a further improvement, the water-blocking assembly includes a water-blocking rubber plate and a water-blocking strip. The water-blocking rubber plate is disposed at the lower part of the side roller seat, and the water-blocking strip is disposed at the upper part of the support plate of the lower roller box.

[0008] As a further improvement, the water-blocking rubber plate includes a connecting section, a retaining section integrally connected to the connecting section, and an arc-shaped transition section connected to the retaining section. The connecting section is located at the lower part of the side roller seat. The retaining section and the connecting section are integrally formed and perpendicular to each other. The arc-shaped transition section extends outward along the end of the retaining section and transitions in an arc shape.

[0009] As a further improvement, the water-blocking strip includes a horizontal section and a vertical section integrally formed with the horizontal section, the horizontal section being disposed on the upper part of the support plate of the lower roller box.

[0010] As a further improvement, the waterproof cylinder assembly includes a sealing gasket installed at the perforation of the support plate and a waterproof cylinder disposed on the sealing gasket, wherein the diameter of the waterproof cylinder is larger than the diameter of the top rod in the top support structure, and the sealing gasket is installed on the outer periphery of the perforation on the support plate by fasteners.

[0011] As a further improvement, the lower roller box includes two opposing side walls and a support plate disposed between the two side walls, so as to divide the lower roller box into upper and lower chambers by the support plate and the two side walls.

[0012] As a further improvement, the upper cavity is provided with a side roller seat, a support roller assembly and a side roller, the lower cavity is provided with a top holding structure, and the support plate is provided with several through holes at equal intervals for corresponding installation of the top holding structure.

[0013] As a further improvement, the support plate is provided with a number of drainage holes, each set of drainage holes being located on both sides of the support plate and symmetrical about the longitudinal center line of the support plate. Each drainage hole extends outward at an incline along the upper surface of the support plate and communicates with the lower end of the support plate.

[0014] As a further improvement, the angle of inclination of the drain hole to the horizontal direction is 20-40 degrees, preferably 30 degrees.

[0015] As a further improvement, the two side walls are arranged in parallel, the support plate is perpendicular to the two side walls, and fixing blocks are correspondingly arranged on the inner circumferential surfaces of the two side walls. The support plate is placed between the two side walls through the fixing blocks.

[0016] The above-mentioned technical solution of the present invention has the following beneficial effects: The straightening machine roller system with waterproof structure of the present invention can effectively prevent external cooling water and impurities such as iron oxide scale from entering below the side roller seat, thereby extending the service life of the roller system, and can accurately control the position of the straightening roller, improve the straightening accuracy of the steel plate, and thus ensure the normal use of the straightening roller lifting and lowering.

[0019] The following embodiments further illustrate the content of the present invention, but should not be construed as limiting the present invention. Any modifications or substitutions made to the methods, steps, or conditions of the present invention without departing from the spirit and essence of the invention are within the scope of protection of the present invention.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings and examples.

[0021] Please see Figures 1 to 2 As shown, the present invention discloses a straightening machine roller system with a waterproof structure, including a lower roller box 5, a side roller seat 3 installed in the lower roller box 5, a support roller assembly 2 disposed in the lower roller box 5 and fixed on the side roller seat 3, a side roller 1 disposed on the support roller assembly 2, a top holding structure 4 disposed in the lower roller box 5, disc springs 6 disposed at both ends of the side roller 1, and a waterproof structure disposed between the top holding structure 4 and the side roller seat 3.

[0022] The lower roller box 5 includes two opposing side walls 501 and a support plate 502 disposed between the two side walls, dividing the lower roller box 5 into upper and lower chambers via the support plate 502 and the side walls. The upper chamber houses a side roller seat 3, a support roller assembly 2, and a side roller 1. The lower chamber houses a top-holding structure 4, and the support plate 502 has several equally spaced through holes for mounting the top-holding structure 4.

[0023] Please refer to the following: Figure 2 As shown, in this embodiment, two side walls 501 are arranged in parallel, and the support plate 502 is perpendicular to the two side walls. Fixing blocks 503 are correspondingly provided on the inner circumferential surfaces of the two side walls 501. The support plate 502 is positioned between the two side walls 501 via the fixing blocks 503, dividing the lower roller box 5 into upper and lower chambers. A side roller seat 3 is provided on the surface of the support plate 502 in the upper chamber. A corresponding supporting structure 4 is provided in each through hole on the support plate 502 to assist the side roller seat 3 in moving along the upper chamber of the lower roller box 5. Several sets of drainage holes 8 are correspondingly provided on the support plate 502 to facilitate the timely drainage of water splashed onto the bottom of the side roller seat. Each set of drainage holes 8 is located on both sides of the support plate 502. Specifically, there are two drainage holes 8 in each set, and they are symmetrical about the longitudinal center line of the support plate 502. Each drainage hole 8 extends outward at an angle along the upper surface of the support plate 502 and communicates with the lower end of the support plate 502. In this embodiment, the angle of inclination of the drainage hole 8 with the horizontal direction is 20 degrees to 40 degrees. Preferably, the angle of inclination of the drainage hole 8 with the horizontal direction is 30 degrees.

[0024] Please refer to the following: Figure 2 As shown, the support roller assembly 2 is placed in the upper cavity of the lower roller box 5 and positioned on the upper part of the side roller seat 3 to support the side roller 1. Specifically, the support roller assembly 2 includes two rows of staggered support rollers 201. A plurality of support rollers 201 in one row are close to the inner circumferential surface of one side wall 501 of the lower roller box 5 and fixed to the upper part of the side roller seat 3. A plurality of support rollers 201 in the other row are close to the inner circumferential surface of the other side wall 501 of the lower roller box 5 and fixed to the upper part of the side roller seat 3. A preset distance is left between the centers of the two rows of staggered support rollers 201 to stably support the side roller 1. In this embodiment, each row of support rollers 201 is designed to have four rollers, which are equally spaced.

[0025] The top holding structure 4 is placed in the lower cavity of the lower roller box 5 and is correspondingly set in each through hole on the support plate 502 to assist the side roller 1 on the side roller seat 3 in moving in the upper cavity of the lower roller box 5.

[0026] Specifically, please refer to the following: Figure 1 as well as Figure 2 As shown, the top-holding structure 4 includes several top-holding components arranged at equal intervals. These components are correspondingly disposed within the through holes of the support plate 502 and can move up and down within these holes. Each top-holding component includes a top rod 401 and an elastic reset member 402 sleeved on the top rod 401. The top rod 401 is placed in the lower cavity of the lower roller box 5, with one end passing through the through hole of the support plate 502 and abutting against the lower circumferential surface of the side roller seat 3. The other end of the top rod 401 forms a retaining protrusion 403. A retaining groove is formed on the outer circumferential surface of the through hole in the support plate 502, and the diameter of the retaining protrusion 403 is smaller than the diameter of the retaining groove. The elastic reset member 402 is a helical spring, and the helical spring is sleeved at the end near the retaining protrusion 403 of the top rod 401.

[0027] A waterproof structure is installed between the top support structure 4 and the side roller seat 3 to prevent water from flowing into the top rod position of the top support structure 4, thus preventing corrosion of the top rod and the elastic reset component 402. Specifically, the waterproof structure includes a water-blocking component installed at the lower part of the side roller seat 3 and the upper part of the support plate 502, and a waterproof cylinder component installed around the perforation of the support plate 502. This component guides external cold water into the drainage trough and discharges it into the slag flushing ditch, preventing water from flowing into the lower part of the side roller seat 3 and causing rust on the top rod and spring. Secondly, it prevents iron oxide scale and other debris from entering the lower part of the side roller seat 3, which could cause the side roller 1 to fail to fall into place and affect the straightening accuracy of the steel plate. The water-blocking component includes a water-blocking rubber plate 7 and a water-blocking strip 11. The water-blocking rubber plate 7 is installed at the lower part of the side roller seat 3 to guide external cold water to flow out of the water trough. The water-blocking strip 11 is installed at the upper part of the support plate 502 of the lower roller box 5 to prevent waste such as iron oxide scale from entering the bottom of the side roller seat and affecting its use.

[0028] The water-blocking rubber plate 7 includes a connecting section, a retaining section integrally connected to the connecting section, and an arc-shaped transition section connected to the retaining section. The connecting section is located at the lower part of the side roller seat 3. The retaining section and the connecting section are integrally formed and perpendicular to each other. The arc-shaped transition section extends outward along the end of the retaining section and transitions in an arc shape. This is to guide external cold water into the drainage trough and discharge it into the slag flushing ditch, preventing water from flowing into the lower part of the side roller seat 3 and causing the top rod and spring to rust. The water-blocking strip 11 includes a horizontal section and a vertical section integrally formed with the horizontal section. The horizontal section is located on the upper part of the support plate 502 of the lower roller box 5 to prevent iron oxide scale and other materials from entering the lower part of the side roller seat 3, causing the side roller 1 to not fall into place and affecting the straightening accuracy of the steel plate.

[0029] A waterproof sleeve assembly is installed on the outer periphery of the perforation in the support plate 502 of the lower roller box 5 to further prevent small amounts of splashed water from entering the top support structure 4 and causing corrosion of the top rod and spring. Specifically, the waterproof sleeve assembly includes a sealing gasket 10 installed at the perforation in the support plate 502 and a waterproof sleeve 12 installed on the sealing gasket 10, with the diameter of the waterproof sleeve 12 being larger than the diameter of the top rod 401 in the top support structure 4. The sealing gasket 10 is installed on the outer periphery of the perforation in the support plate 502 by fasteners.

[0030] The side roller 1 is placed on two rows of staggered support rollers 201. The two rows of staggered support rollers are set on the side roller seat 3. The side roller seat and the lower roller box of the entire roller system have corresponding guide structures to achieve overall lifting and lowering. A corresponding top support structure 4 is set under the side roller seat 3. There is a corresponding helical spring between the top rod of the top support structure 4 and the lower roller box to assist the side roller in descending, so that the side roller can actively rise and fall, thereby adjusting the size of the roller gap and controlling the thickness of the plate. In addition, a waterproof structure set between the top support structure 4 and the side roller seat 3 prevents water from flowing into the top rod position of the top support structure 4, preventing the top rod and elastic reset part 402 from rusting, and preventing iron oxide scale from entering below the side roller seat 3, causing the side roller 1 to not fall into place and affecting the straightening accuracy of the steel plate. At the same time, drainage holes 8 are correspondingly set on the support plate 502 of the lower roller box 5, so that water splashed to the bottom of the side roller seat can be discharged in time.

[0031] In summary, the straightening machine roller system of the present invention with a waterproof structure can effectively prevent external cooling water and impurities such as iron oxide scale from entering below the side roller seat, thereby extending the service life of the roller system. Furthermore, it can precisely control the position of the straightening rollers, improve the straightening accuracy of the steel plate, and thus ensure the normal operation of the straightening roller lifting mechanism.

[0032] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
