Description

Technical Field

[0001] This utility model relates to the field of strip rolling technology, and in particular to a rolling device for improving the uniformity of strip density. Background Technology

[0002] Metal rolling is a specialized equipment used to roll metal billets to a certain thickness using pressure from rolls. It is widely used in the processing of metal materials. Traditional rolling equipment typically consists of one or more pairs of relatively rotating rolls. The rolling efficiency and finished product thickness are controlled by changing the pressure and gap between the rolls. In existing technologies, the slab rolling process faces a significant limitation: the roll gap cannot be adjusted quickly and easily, which restricts the diversity of product specifications and production flexibility.

[0003] To address this issue, utility model patent CN221734422U discloses an adjustable slab rolling device, belonging to the field of rolling technology. It solves the technical problem of quickly and conveniently adjusting the gap between rolls. The solution is as follows: symmetrical fixed supports are arranged above the base; roll gap adjustment components are respectively mounted on two fixed supports; a driven shaft is arranged across the two sets of fixed supports; a driven gear set and a driven roll are installed on the driven shaft; a replacement component is installed at the position of the driven gear set; a central support frame is arranged on the base between the fixed supports; a drive shaft is arranged across the central support frame and the fixed supports; a drive gear and a drive roll are installed on the drive shaft; the driven roll and the drive roll are located on the same side of the central support frame. This utility model, by adjusting the driven gears of different nominal diameters in the driven gear set to mesh with the drive gear, can quickly and conveniently adjust the gap between the driven roll and the drive roll, thus enabling the production of slabs of different thicknesses using the same rolling equipment.

[0004] However, in actual use, we found that the above device can only adjust for multiple thicknesses and cannot achieve stepless adjustment within the adjustable range, resulting in poor overall adaptability. Therefore, it is necessary to consider how to solve the above problem. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rolling device that improves the uniformity of strip density. Compared with existing technologies, this rolling device can achieve stepless adjustment within an adjustable range, is applicable to various strips, and further improves the adaptability of the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rolling apparatus for improving the uniformity of strip density includes a base plate, two vertical plates symmetrically fixedly connected to the upper end of the base plate, a first rolling roll rotatably connected between the two vertical plates, and a second rolling roll disposed between the two vertical plates; a lifting mechanism for moving the second rolling roll up and down, each of the two vertical plates having a strip-shaped opening, an electric telescopic rod installed at the inner top of each of the two strip-shaped openings, and a slider fixedly connected to the telescopic end of each of the two electric telescopic rods; two rotating shaft ends of the second rolling roll being rotatably connected to the corresponding sliders; and a driving mechanism for simultaneously driving the two second rolling rolls to rotate.

[0008] Preferably, each slider is slidably connected to the inner wall of the corresponding strip-shaped opening.

[0009] Preferably, the driving mechanism includes a connecting plate fixedly connected to the right side of the vertical plate, a rotating shaft passing through the connecting plate, the rotating shaft being rotatably connected to the connecting plate via a bearing, a third bevel gear being fixedly connected to the lower end of the rotating shaft, the right end rotating shaft of the first rolling roll passing through the corresponding vertical plate and equipped with a fourth bevel gear, the third bevel gear meshing with the fourth bevel gear.

[0010] Preferably, an L-shaped plate is fixedly connected to the lower end of the slider on the right side, and a rotating cylinder is provided through the horizontal part of the L-shaped plate. The rotating cylinder and the horizontal part of the L-shaped plate are rotatably connected by a bearing. The right end of the rotating shaft of the second rolling roll passes through the corresponding slider and is fixedly connected to a first bevel gear. A second bevel gear is installed on the rotating cylinder. The first bevel gear meshes with the second bevel gear. The upper end of the rotating shaft passes through the rotating cylinder.

[0011] Preferably, a strip-shaped guide groove is provided on one side of the rotating shaft, and a guide bar is fixedly connected to the inner side of the rotating cylinder. One side of the guide bar extends into the strip-shaped guide groove and is slidably connected.

[0012] Preferably, a drive motor is installed on the right side of the vertical plate located on the right side, and the output shaft of the drive motor is fixedly connected to the upper end of the rotating shaft.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] During the rolling operation, the drive motor, rotating shaft, and bevel gear transmission structure stably drive the first and second rolling rolls to rotate synchronously in opposite directions, efficiently completing the strip rolling and making the strip uniformly thinner. When the strip thickness changes and the rolling gap needs to be adjusted, the synchronous controller controls the electric telescopic rod to extend and retract synchronously, allowing for precise and stepless adjustment of the second rolling roll position, achieving flexible adaptation of the rolling gap. During the adjustment process, the unique adaptive transmission structure ensures that rolling is uninterrupted. At the same time, the two rolling rolls are subjected to force at both ends, resulting in uniform pressure distribution and greatly improving the uniformity of strip density.

[0020] 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.

[0021] Reference Figures 1-4 A rolling device for improving the uniformity of strip density includes a base plate 1, two vertical plates 2 are symmetrically fixedly connected to the upper end of the base plate 1, a first rolling roll 3 is rotatably connected between the two vertical plates 2, and a second rolling roll 7 is arranged between the two vertical plates 2.

[0022] It also includes a lifting mechanism for moving the second rolling roll 7 up and down. Each of the two vertical plates 2 has a strip-shaped opening 4. An electric telescopic rod 6 is installed on the inner top of each of the two strip-shaped openings 4. A slider 5 is fixedly connected to the telescopic end of each of the two electric telescopic rods 6. The two rotating shaft ends of the second rolling roll 7 are respectively rotatably connected to the corresponding slider 5. Each slider 5 is slidably connected to the inner wall of the corresponding strip-shaped opening 4. It should be noted that the two electric telescopic rods 6 are controlled by a synchronous controller, which can realize the synchronous extension and retraction of the two electric telescopic rods 6.

[0023] The system also includes a drive mechanism for simultaneously driving the two second rolling rolls 7 to rotate. The drive mechanism includes a connecting plate 14 fixedly connected to the right side of the vertical plate 2. A rotating shaft 9 is provided through the connecting plate 14. The rotating shaft 9 and the connecting plate 14 are rotatably connected by a bearing. A third bevel gear 15 is fixedly connected to the lower end of the rotating shaft 9. The rotating shaft at the right end of the first rolling roll 3 passes through the corresponding vertical plate 2 and is equipped with a fourth bevel gear 16. The third bevel gear 15 and the fourth bevel gear 16 mesh.

[0024] The lower end of the slider 5 on the right side is fixedly connected to an L-shaped plate 10. A rotating cylinder 13 is installed through the horizontal part of the L-shaped plate 10. The rotating cylinder 13 and the horizontal part of the L-shaped plate 10 are rotatably connected by a bearing. In this way, the L-shaped plate 10 can support the rotating cylinder 13. The right end of the rotating shaft of the second rolling roller 7 passes through the corresponding slider 5 and is fixedly connected to a first bevel gear 11. A second bevel gear 12 is installed on the rotating cylinder 13. The first bevel gear 11 and the second bevel gear 12 mesh. The upper end of the rotating shaft 9 passes through the rotating cylinder 13. A strip-shaped guide groove 17 is opened on one side of the rotating shaft 9. A guide strip 18 is fixedly connected to the inner side of the rotating cylinder 13. One side of the guide strip 18 extends into the strip-shaped guide groove 17 and is slidably connected. A drive motor 8 is installed on the right side of the vertical plate 2 on the right side. The output shaft of the drive motor 8 is fixedly connected to the upper end of the rotating shaft 9.

[0025] In this invention, when the device is in its initial state, an initial rolling gap is formed between the first rolling roll 3 and the second rolling roll 7, and the strip to be rolled is fed into the initial rolling gap between the first rolling roll 3 and the second rolling roll 7.

[0026] When the drive motor 8 is started, its output shaft begins to rotate, causing the rotating shaft 9, which is fixedly connected to it, to rotate synchronously. The rotating shaft 9 is rotatably connected to the connecting plate 14 through bearings, ensuring the stability of the rotation of the rotating shaft 9.

[0027] The third bevel gear 15, which is fixedly connected to the lower end of the rotating shaft 9, rotates synchronously with the rotating shaft 9. Since the third bevel gear 15 meshes with the fourth bevel gear 16 on the right end of the rotating shaft of the first rolling roll 3, the fourth bevel gear 16 drives the first rolling roll 3 to rotate under the action of bevel gear transmission. When the rotating shaft 9 rotates, the guide bar 18 slides in the strip-shaped guide groove 17, and at the same time drives the rotating cylinder 13 to rotate. The second bevel gear 12 installed on the rotating cylinder 13 rotates synchronously with the rotating cylinder 13. Since the second bevel gear 12 meshes with the first bevel gear 11, which is fixedly connected to the right end of the rotating shaft of the second rolling roll 7, the first bevel gear 11 drives the second rolling roll 7 to rotate under the action of bevel gear transmission. The rotation direction of the second rolling roll 7 is matched with the rotation direction of the first rolling roll 3, and together they roll the strip, so that the strip is squeezed and thinned in the rolling gap.

[0028] When the rolling gap needs to be adjusted according to the change in strip thickness, the two electric telescopic rods 6 are controlled to extend and retract synchronously by a synchronous controller. The telescopic ends of the electric telescopic rods 6 are fixedly connected to the sliders 5, and the sliders 5 are slidably connected to the inner wall of the strip opening 4. Driven by the electric telescopic rods 6, the sliders 5 slide up and down inside the strip opening 4. Since the two rotating shaft ends of the second rolling roll 7 are respectively rotatably connected to the corresponding sliders 5, when the sliders 5 slide up and down, they drive the second rolling roll 7 to move up and down synchronously. During the up and down movement of the second rolling roll 7, the rotational connection between the rotating cylinder 13 and the L-shaped plate 10, and the connection between the rotating shaft 9 and the rotating cylinder 13 via the guide strip 18 are maintained. The sliding connection between the strip guide groove 17 and the transmission structure ensures adaptive adjustment. Even if the position of the second rolling roll 7 changes, the rotating shaft 9 can still drive the first rolling roll 3 to rotate through the third bevel gear 15 and the fourth bevel gear 16. At the same time, it drives the second rolling roll 7 to rotate through the rotating cylinder 13, the second bevel gear 12 and the first bevel gear 11, so that the rolling process can continue when the rolling gap is adjusted. It can achieve stepless adjustment within the adjustable range. Furthermore, since both ends of the first rolling roll 3 and the second rolling roll 7 are subjected to force, the pressure applied to the strip is relatively uniform during rolling, and the density of the pressed strip is relatively consistent.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
