Description

Technical Field

[0001] This utility model relates to the field of ultra-thin aluminum plate production technology, specifically to a roll assembly for precision rolling of ultra-thin aluminum plates. Background Technology

[0002] The roll assembly for precision rolling of thin aluminum sheets is the core device in aluminum sheet rolling production. It is mainly used to process thick aluminum billets into ultra-thin aluminum sheets through rolling process. It consists of working rolls, support rolls, roll system adjustment mechanism, etc. In the production of ultra-thin aluminum sheets, cold rolling is widely used because it can achieve high-precision rolling. However, this process places extremely high demands on the deformation control of the rolls. During long-term operation, the rolls generate a large amount of heat due to the contact friction with the aluminum sheet. This can easily lead to thermal expansion of the rolls. The thermal expansion of the rolls not only affects the rolling accuracy but may also shorten the service life of the rolls, and in severe cases, may even cause production accidents. To address the issue of thermal expansion of the rolls, the industry practice is to install copper cooling water pipes inside the rolls. These pipes absorb the heat generated by the rolls, thereby reducing their temperature. However, in actual use, new problems have gradually emerged. Because the rolls rotate continuously during operation, they generate vibrations. These vibrations are transmitted to the connection points of the connecting pipes. The connection points are areas where structural stress is relatively concentrated. Under prolonged and high-frequency vibration and impact, the crystal structure inside the metal material will continuously undergo micro-slippage and dislocation, leading to a gradual deterioration of the material's mechanical properties. This accelerates the metal fatigue phenomenon at the connection points, resulting in damage to the connection points and affecting the normal operation of the cooling system. Therefore, a roll assembly for precision rolling of ultra-thin aluminum plates is proposed to address the above problems. Utility Model Content

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A roll assembly for precision rolling of ultra-thin aluminum plates includes a roll body 1, a bearing mechanism 2 fixed inside the roll body 1, and anti-torsion conveying mechanisms 3 fixed through both ends of the bearing mechanism 2. An installation cavity 4 is opened on the inner side of the roll body 1. The bearing mechanism 2 includes a bearing roll 21, a roll neck 22 fixed at the center inside the bearing roll 21, conveying cavities 23 opened at both ends inside the roll neck 22, and a support rib 24 and a cooling pipe 25 fixed on the outer wall of the roll neck 22. The anti-torsion conveying mechanism 3 includes a first flange disk 31, a buffer 32 clamped at one end of the first flange disk 31, a second flange disk 33 clamped at one end of the buffer 32, a protective tube 34 installed inside the buffer 32, and a support seat 35 rotatably mounted at one end of the protective tube 34.

[0017] As a further implementation of this scheme, the shape of the support rib 24 and the shape of the cooling pipe 25 are both spirally arranged. The vertical cross-sectional shape of the support rib 24 and the vertical cross-sectional shape of the cooling pipe 25 are both rectangular. The width of the support rib 24 is 1.5 times the width of the cooling pipe 25. The outer side of the support rib 24 and the outer side of the cooling pipe 25 are both in contact with the inner side of the mounting cavity 4. The two ends of the support rib 24 are respectively fixedly connected to the two ends inside the mounting cavity 4. The two ends of the cooling pipe 25 extend into the inside of the roll neck 22. The two ends of the cooling pipe 25 are respectively connected to the inside of the two conveying cavities 23. Connecting grooves 26 for adapting the cooling pipe 25 are opened on both sides of the surface of the roll body 1. Specifically, in this design, the spiral support rib 24 and cooling pipe 25 fit tightly against the inner side of the mounting cavity 4. The support rib 24 is wider, which can enhance the structural stability. The spiral path extends the contact time between the cooling pipe 25 and the roll body 1, improving the heat dissipation efficiency. The connecting groove 26 ensures that the cooling pipe 25 is installed firmly, allowing the cooling and support functions to work together. As a further implementation of this solution, the buffer 32 includes a buffer body 321. The outer wall of the buffer body 321 is provided with buffer cavities 322 arranged in a circle. Both ends of the buffer body 321 are provided with a set of spring mounting positions. A support spring 324 is fixed inside the spring mounting position. A fitting block 325 is fixed at the front end of the support spring 324. The fitting block 325 fits against the inner side of the first flange disk 31 and the second flange disk 33. A mounting groove 323 is provided in the spring mounting position. Specifically, the buffer cavities 322 of the buffer body 321 are arranged in a circular pattern, which can evenly disperse circumferential vibration. The mounting groove 323 is in the spring mounting position, which, together with the support spring 324 and the fitting block 325, can effectively buffer longitudinal vibration. The fitting block 325 ensures a tight connection with the first flange disk 31 and the second flange disk 33, improving the overall shock absorption effect and reducing component fatigue. As a further implementation of this solution, the end of the first flange disk 31 near the buffer body 321 has a protruding structure. The first flange disk 31 and the second flange disk 33 have the same structure. The interior of the first flange disk 31 and the second flange disk 33 are both hollow structures. The included angle between the first flange disk 31 and the second flange disk 33 is 90°. Specifically, the raised structure of the first flange disk 31 facilitates engagement with the buffer 32, enhancing connection stability. The cavity structure of the first flange disk 31 and the second flange disk 33 reduces weight without affecting strength. The 90° angle design makes the layout of the protective tube 34 reasonable, adapting to the force transmission direction when the roll body 1 rotates, and improving the operational coordination of the anti-torsion conveying mechanism 3. As a further implementation of this solution, the support base 35 includes a support base body 351, with mounting seats fixed on both sides of the support base body 351. A bearing 352 is fixed at one end of the support base body 351 near the second flange disk 33. The second flange disk 33 is embedded in the inner side of the bearing 352, and the second flange disk 33 is rotatably connected to the bearing 352. A water flow channel 353 is opened at the center inside the support base body 351, and an inlet and outlet 354 for connecting the water flow channel 353 is opened at the top of the support base body 351. Specifically, the bearing 352 allows the second flange disk 33 to rotate smoothly, reducing friction loss; the water flow channel 353 ensures efficient flow of the cooling medium; and the inlet and outlet 354 facilitates connection with external pipes, enabling the support body 351 to provide stable support and efficiently transport the cooling medium, connecting internal and external systems. As a further implementation of this solution, the protective pipe 34 includes a protective pipe body 341, which is embedded in the interior of the buffer body 321. One end of the protective pipe body 341 passes through the interior of the first flange disk 31 and is fixedly connected to the interior of the conveying cavity 23. The outer wall of the protective pipe body 341 is provided with a movable groove 342, and the other end of the protective pipe body 341 is fixed with a connecting ring 343. The connecting ring 343 is rotatably connected to the interior of the water flow channel 353 through a sealing element. The position of the movable groove 342 corresponds to the position of the buffer body 321. Specifically, the protective tube body 341 is embedded in the buffer body 321, and the movable groove 342 corresponds to the position of the buffer body 321. It can deform with the buffer 32 to enhance shock absorption adaptability, reduce the continuous effect of alternating stress on metal parts, and delay the occurrence of fatigue damage. The connecting ring 343 cooperates with the sealing element to ensure that the cooling medium is sealed and rotates flexibly during transportation, ensuring stable cooling circulation and reducing the damage of vibration to the protective tube 34.

[0018] Workflow: External cooling medium (such as cooling water) enters the water flow channel 353 of one of the support bases 35 through a pipe connected to the inlet / outlet 354 of one of the support bases 35; The cooling medium in the water flow channel 353 enters the protective tube 34 through the rotating connection of the seal. Since one end of the protective tube 34 passes through the interior of the second flange disk 33 and is connected to the water flow channel 353, the cooling medium can flow smoothly in the protective tube 34. The other end of the protective tube 34 passes through the interior of the first flange disk 31 and is fixedly connected to the conveying cavity 23 on the roller neck 22. The cooling medium enters the conveying cavity 23 through the protective tube 34. Cooling medium flows from conveying chamber 23 into cooling pipe 25. Cooling pipe 25 is spirally arranged, and its outer side is in contact with the mounting cavity 4 inside the roll body 1. During the process of cooling medium flowing through cooling pipe 25, it can fully absorb the heat generated by the roll body 1 during operation, thereby cooling the roll body 1. After absorbing heat, the cooling medium re-enters the delivery chamber 23 from the other end of the cooling pipe 25, and then flows back to the water flow channel 353 of the corresponding support seat 35 through the protective pipe 34 on the other side. The connection method of the protective pipe 34 is the same as that of the protective pipe 34 on the input side. Finally, it is discharged through the pipe connected to the inlet and outlet 354 of the support seat 35, thus completing the entire cooling cycle. During the rotation of the roll body 1, circumferential and longitudinal vibrations are generated. When the vibration is transmitted to the anti-torsion conveying mechanism 3, the buffer cavity 322 in the buffer 32 will cancel or weaken the circumferential vibration. At the same time, the mounting groove 323 in the buffer 32 will cancel or weaken the longitudinal vibration. In addition, the movable groove 342 of the protective tube 34 corresponding to the position of the buffer 32 can better move and deform with the buffer 32 to further cancel the vibration, reduce the continuous effect of alternating stress on the metal parts, and delay the occurrence of fatigue damage. The support rib 24 in the bearing mechanism 2 is spirally arranged. Its vertical cross section is rectangular and its width is greater than that of the cooling pipe 25. The outer side of the support rib 24 fits against the inner side of the mounting cavity 4, and its two ends are fixedly connected to the two ends inside the mounting cavity 4, which can provide a solid support for the roll body 1 and the bearing roll 21, enhance the structural stability of the entire assembly, ensure that the roll body 1 maintains a good shape during the precision rolling process, and ensure the rolling accuracy of the ultra-thin aluminum plate.
