Description

Technical Field

[0001] This utility model relates to the field of rolling mill rolls, specifically a magnetic levitation tension roller device. Background Technology

[0002] Steel rolling refers to the pressure processing process of changing the shape of steel ingots and billets between rotating rolls. Like other pressure processing methods, the purpose of steel rolling is twofold: firstly, to obtain the desired shape, such as steel plates, strips, wire rods, and various structural steel sections; and secondly, to improve the internal quality of the steel. Common examples include automotive steel sheets, bridge steel, boiler steel, pipeline steel, rebar, reinforcing bars, electrical silicon steel, galvanized sheets, tinplate, and even train wheels, all of which are processed through steel rolling.

[0003] In existing technologies, steel rolling mainly involves shaping steel by rotating two rolls, thereby changing the shape and size of the steel to obtain the desired shape. Steel rolling is mainly divided into two types: hot rolling and cold rolling. Hot rolling is suitable for shaping steel softened at high temperatures and for mass production, while cold rolling is suitable for producing steel that requires higher precision and surface quality. Rolls are usually installed in the groove of the rolling mill to rotate. However, over a long period of time, the rotational friction between the rolls and the rolling mill will increase the frictional wear of the rolls and increase energy consumption, thereby shortening the service life of the rolls. Utility Model Content

[0004] To address the shortcomings of existing technologies, which cause increased frictional wear and energy consumption and shortened service life of rolls due to long-term rotational friction between the rolls and the rolling mill, this invention proposes a magnetic levitation tension roll device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a magnetic levitation tension roller device, including a fixed frame, and a steel rolling mechanism is provided on one side of the fixed frame;

[0006] The rolling mechanism includes a support plate, one side of which is fixedly connected to one side of a fixed frame. A motor is fixedly connected to the top of the support plate, and the output shaft of the motor is fixedly connected to a first roll. A first hollow groove is formed on the surface of the fixed frame, and the surface of the first roll is rotatably connected to the inner cavity of the first hollow groove. A second hollow groove is formed on the surface of the fixed frame, and an electromagnet is provided in the inner cavity of the second hollow groove. A second roll is provided on the top of the electromagnet.

[0007] Preferably, the surface of the fixing frame is provided with a third hollow groove and a limiting groove. A stop block is slidably connected to the inner cavity of the third hollow groove. A limiting block is fixedly connected to the top of the stop block, and one side of the limiting block is slidably connected to the inner cavity of the limiting groove.

[0008] Preferably, the inner cavity of the fixing frame is provided with a fourth hollow groove, the inner cavity of the fourth hollow groove is fixedly connected to a first magnet plate, and one side of the stop block is fixedly connected to a second magnet plate.

[0009] Preferably, a connecting block is fixedly connected to one side of the fixing frame, and an arc-shaped block is provided at the bottom of the second roller, with the surface of the arc-shaped block fixedly connected to one side of the connecting block.

[0010] Preferably, the surface of the electromagnet is provided with a protective shell, the bottom of which is fixedly connected to the inner cavity of the second hollow groove, and the surface of the protective shell is provided with a through hole.

[0011] Preferably, a hollow block is fixedly connected to the surface of the electromagnet, and a threaded groove is provided in the inner cavity of the fixing frame. The hollow block and the inner cavity of the threaded groove are threadedly connected by bolts.

[0012] Preferably, a rubber block is provided at the bottom of the second roll, and the surface of the rubber block is fixedly connected to the inner cavity of the arc-shaped block.

[0013] The advantages of this utility model are:

[0014] This invention achieves magnetic levitation of the second roll within a hollow groove by energizing an electromagnet, which generates electromagnetic force. The second roll, made of permanent magnet material, repels the electromagnet. A motor then drives the first roll to rotate, conveying the steel to be cold-rolled between the first and second rolls. The rotation of the first and second rolls performs the cold rolling process. Because the second roll is magnetically levitated within the hollow groove, it achieves a contactless connection with the fixing frame, thus reducing frictional resistance, frictional damage, and energy consumption, thereby extending its service life. This solves the problem that prolonged rotational friction between the second roll and the rolling mill increases frictional wear and energy consumption, ultimately shortening the second roll's lifespan.

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a magnetic levitation tension roller device. (Refer to...) Figure 1-2 A magnetic levitation tension roller device includes a fixed frame 1, a steel rolling mechanism 2 is provided on one side of the fixed frame 1, the interior of the fixed frame 1 can be used to place the steel rolling mechanism 2, and the steel rolling mechanism 2 can roll and shape steel.

[0025] The rolling mechanism 2 includes a support plate 201, one side of which is fixedly connected to one side of the fixed frame 1. A motor 202 is fixedly connected to the top of the support plate 201. The output shaft of the motor 202 is fixedly connected to a first roll 204. A first hollow groove 203 is opened on the surface of the fixed frame 1. The surface of the first roll 204 is rotatably connected to the inner cavity of the first hollow groove 203. A second hollow groove 207 is opened on the surface of the fixed frame 1. An electromagnet 206 is provided in the inner cavity of the second hollow groove 207. A second roll 205 is provided on the top of the electromagnet 206.

[0026] The first hollow groove 203 on the surface of the fixed frame 1 can be used to place the first roll 204, so that the first roll 204 can rotate stably inside the fixed frame 1. The second roll 205 is located at the bottom of the first roll 204. The first roll 204 and the second roll 205 can perform steel rolling and shaping treatment by rotating. The support plate 201 can be used to support the motor 202, and the motor 202 can drive the first roll 204 to rotate, making the rotation of the first roll 204 more convenient and enabling it to actively rotate to drive the steel for rolling. The interior of the second hollow groove 207 can be used to place the second roll 205 and the electromagnet 206, and the electromagnet 206 is located at the bottom of the second roll 205. The second roll 205 is made of permanent magnet material, such as neodymium iron boron and AlNiCo, but permanent magnet material is not suitable for hot rolling. Since the steel is cold-rolled, the first roll 204 and the second roll 205 can only perform cold rolling on the steel. The electromagnet 206 can be energized to generate electromagnetic force, so that the upper second roll 205 can repel the electromagnet 206 and thus magnetically levitate above the electromagnet 206 and inside the second hollow groove 207. At this time, the second roll 205 can cooperate with the first roll 204 to roll the steel. The magnetically levitated second roll 205 can achieve contactless connection, thereby achieving contactless frictional resistance, reducing frictional damage and energy consumption of the second roll 205, and improving the service life of the second roll 205. Furthermore, by controlling the current of the electromagnet 206, the magnetic field strength can be adjusted, thereby controlling the magnetic levitation height of the second roll 205, so as to adjust the distance between the first roll 204 and the second roll 205, and thus achieve the function of adjusting tension.

[0027] Reference Figure 4 The surface of the fixed frame 1 is provided with a third hollow groove 3 and a limiting groove 5. A stop block 4 is slidably connected to the inner cavity of the third hollow groove 3. A limiting block 6 is fixedly connected to the top of the stop block 4. One side of the limiting block 6 is slidably connected to the inner cavity of the limiting groove 5. The third hollow groove 3 allows the second roller 205 to be easily removed from the inside of the second hollow groove 207 for replacement. The stop block 4 can block the third hollow groove 3, making it difficult for the second roller 205 to detach from the third hollow groove 3 during normal use. The inside of the limiting groove 5 can be used to place the limiting block 6, and the limiting block 6 can limit the stop block 4, so that the stop block 4 can be stably placed inside the third hollow groove 3 and is not easily squeezed out of the third hollow groove 3 by the second roller 205.

[0028] Reference Figure 4The inner cavity of the fixed frame 1 is provided with a fourth hollow groove 7. A first magnet plate 8 is fixedly connected to the inner cavity of the fourth hollow groove 7. A second magnet plate 17 is fixedly connected to one side of the stop block 4. The interior of the fourth hollow groove 7 can be used to place the first magnet plate 8, while one side of the stop block 4 can be connected to the second magnet plate 17. The first magnet plate 8 and the second magnet plate 17 are located on both sides of the second roll 205, respectively, and both repel the second roll 205. This makes it difficult for the second roll 205 to come into contact with the inner wall of the second hollow groove 207 and generate friction when it rotates inside the second hollow groove 207, thereby reducing friction loss. In addition, the first magnet plate 8 and the second magnet plate 17 are small in size and have weak magnetic fields, so they will not affect the normal magnetic levitation of the second roll 205 by the electromagnet 206.

[0029] Reference Figure 5 A connecting block 14 is fixedly connected to one side of the fixed frame 1. An arc-shaped block 15 is provided at the bottom of the second roller 205. The surface of the arc-shaped block 15 is fixedly connected to one side of the connecting block 14. The connecting block 14 can connect to the arc-shaped block 15, so that the arc-shaped block 15 can be located on the lower side of the second roller 205. The arc-shaped block 15 can support the second roller 205 when it is not in use, so that the second roller 205 will not hit the electromagnet 206 when it is not in use and falls downward.

[0030] Reference Figure 5 The surface of the electromagnet 206 is provided with a protective shell 9. The bottom of the protective shell 9 is fixedly connected to the inner cavity of the second hollow groove 207. The surface of the protective shell 9 is provided with a through hole 10. The protective shell 9 can protect the electromagnet 206, while the through hole 10 can facilitate the placement and passage of wires on the surface of the electromagnet 206.

[0031] Reference Figure 3 A hollow block 11 is fixedly connected to the surface of the electromagnet 206. A threaded groove 12 is provided in the inner cavity of the fixing frame 1. Bolts 13 are threadedly connected to the inner cavities of the hollow block 11 and the threaded groove 12. Bolts 13 can be connected to the interior of the hollow block 11 and the threaded groove 12 to connect the fixing frame 1 and the electromagnet 206. At the same time, bolts 13 can also be rotated to disengage from the hollow block 11 and the threaded groove 12, so as to disassemble and replace the electromagnet 206.

[0032] Reference Figure 3 A rubber block 16 is provided at the bottom of the second roller 205. The surface of the rubber block 16 is fixedly connected to the inner cavity of the arc-shaped block 15. The rubber block 16 can buffer the second roller 205 that falls into the arc-shaped block 15.

[0033] Working Principle: When using this device, the electromagnet 206 is first energized, causing it to generate electromagnetic force. The second roller 205, made of permanent magnet material, repels the electromagnet 206, thus achieving magnetic levitation of the second roller 205 inside the second hollow groove 207. Then, the motor 202 is started to drive the first roller 204 to rotate. Finally, the steel to be cold-rolled is conveyed between the first roller 204 and the second roller 205. The rotation of the first roller 204 and the second roller 205 performs cold rolling on the steel. Because the second roller 205 is magnetically levitated inside the second hollow groove 207, it can achieve a non-contact connection with the fixed frame 1, thereby achieving non-contact frictional resistance, reducing frictional damage and energy consumption of the second roller 205, and improving the efficiency of the second roller. The service life of the roll 205 is extended, and the magnetic field strength can be adjusted by controlling the current of the electromagnet 206, thereby controlling the magnetic levitation height of the second roll 205 to adjust the distance between the first roll 204 and the second roll 205, thus achieving the effect of adjusting tension. Furthermore, the first magnet plate 8 and the second magnet plate 17 inside the second hollow groove 207 are located on both sides of the second roll 205 and repel the second roll 205, so that the second roll 205 will not contact the inner wall of the second hollow groove 207, further reducing friction loss. This solves the problem that the rotational friction between the second roll 205 and the rolling mill over a long period of time will increase the friction loss of the second roll 205 and increase energy consumption, thereby shortening the service life of the second roll 205.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
