[0035] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0036] As shown in Figures 1 to 6, this utility model discloses a cooling device applied to aluminum material 400. The cooling device is used to support and reduce the surface temperature of the aluminum material 400 during the production process. The cooling device 100 includes a tank 1, a cooling pipe 2, and a roller assembly 3. The tank 1 has a cuboid structure and is located between the rolling mill 300 and the take-up mill 500 of the continuous rolling mill during aluminum production. The tank 1 supports the aluminum material 400 to ensure that it maintains a stable position during transport, preventing it from shifting or deforming. The cooling pipe 2 is located at the top of the tank 1 and contains an emulsion. The emulsion provides lubrication and cooling to the aluminum material 400, rapidly absorbing the heat generated during rolling to prevent the aluminum material 400 from overheating and thus reducing surface oxidation. Regarding the formation of cracks, it should be noted that the cooling pipe 2 can also contain water or other liquids for lubrication and cooling of the aluminum material 400. The cooling pipe 2 is adapted to meet specific needs. It consists of a main pipe 21 and multiple branch pipes 22. The branch pipes 22 are spaced apart along the axial direction of the main pipe 21 (as shown in the x direction in Figure 1) to ensure uniform cooling and avoid localized overheating. The cooling pipe 2 is made of high-temperature and corrosion-resistant materials, such as stainless steel, special alloys, or composite materials, to facilitate long-term use in high-temperature environments. It can be adapted to meet specific needs, as long as it can contain the emulsion without causing a reaction. This application does not impose excessive restrictions on this. During assembly, the main pipe 21 is connected to the interior of the tank 1 through multiple branch pipes 22, allowing the emulsion to flow smoothly to the surface of the aluminum material 400.

[0037] Referring again to Figures 1 to 6, a roller assembly 3 is provided at the end of the tank 1. The roller assembly 3 is used to transport the aluminum material 400, enabling it to smoothly pass through the cooling device 100 and enter the next production process, ensuring the normal production of the aluminum material 400. It should be noted that the aluminum material 400 can be in the form of an aluminum rod or an aluminum bar, with the aluminum rod having a larger cross-sectional area than the aluminum bar. For example, in the existing technology for producing aluminum materials (such as aluminum rods), a three-pass continuous rolling mill is required. There is a gap between this rolling mill and the bar-receiving machine. When the aluminum material is located between the rolling mill and the bar-receiving machine, due to its larger cross-section and certain weight, it will deform and bend downwards, thus affecting the quality of the aluminum material. In this application, a cooling device 100 is installed between the rolling mill 300 and the roll take-up machine 500. After the aluminum material 400 is rolled, it is directly conveyed to the cooling device 100. The tank 1 of the cooling device 100 can effectively restrict the position of the aluminum material 400. At the same time, the cooling pipe 2 on the cooling device 100 can uniformly provide emulsion to the aluminum material 400, effectively reducing the temperature of the aluminum material 400 to ensure the quality of the aluminum material 400.

[0038] In some embodiments, as shown in Figures 1 to 3, along the conveying direction of the aluminum material 400 (x direction as shown in Figure 3), the two ends of the trough 1 have an inlet 11 and an outlet 12, respectively. The inlet 11 is connected to one end of the rolling mill 300, and the outlet 12 is connected to one end of the take-up machine 500, ensuring that the aluminum material 400 enters the trough 1 from the inlet 11 and is conveyed to the take-up machine 500 from the outlet 12. A groove 13 is provided at the bottom of the trough 1. The shape of the groove 13 can be adapted as needed. In one example, the groove 13 is close to the inlet 11 or close to the outlet 12 (as shown in Figures 1 and 2). The roller assembly 3 is located in the groove 13. During the conveying process, the roller assembly 3 can reduce the direct friction between the aluminum material 400 and the bottom of the trough 1, reduce wear, and further stabilize and smoothly convey the aluminum material 400, thereby improving production efficiency. In another example, both the inlet 11 and the outlet 12 are provided with grooves 13, and the roller assembly 3 is located within the grooves 13. When the aluminum material 400 is on the cooling device 100, the aluminum material 400 can move through the roller assembly 3 and be conveyed with double lubrication by the emulsion, reducing friction and thus increasing the conveying force. In the height direction of the tank 1 (the z-direction shown in Figure 1), the roller assembly 3 is flush with the bottom of the tank 1, reducing the bending of the aluminum material 400 and preventing deviation from the track or irregular movement.

[0039] In some embodiments, as shown in Figures 1 to 4, the roller assembly 3 is used to stably convey aluminum material 400, ensuring that the aluminum material 400 maintains balanced and uniform movement during the cooling process. The roller assembly 3 includes two support seats 31, a connecting shaft 32, and a roller 33. The two support seats 31 are installed on the two side walls of the trough 1 to provide support for the connecting shaft 32 and the roller 33. The roller 33 is sleeved on the connecting shaft 32, which is located between the two support seats 31 and is fixedly connected to the support seats 31, ensuring the stability of the roller 33 and preventing the roller 33 from shifting or shaking during operation, thus achieving smooth conveying of the aluminum material 400.

[0040] In some embodiments, as shown in Figures 1 and 2, the support base 31 has a U-shaped structure and is welded to the trough 1. The U-shaped support base 31 has good adaptability and load-bearing capacity, and is easy to install. It can prevent the aluminum material 400 from shaking during use. The roller 33 is a U-shaped roller. The middle part of the U-shaped roller is flush with the bottom surface of the trough 1. The U-shaped roller matches the surface of the aluminum material 400, which can increase the fit and reduce friction. The roller 33 rotates in the direction of conveying the aluminum material 400 (x direction as shown in Figure 1) to facilitate the conveying of the aluminum material 400 to the next production process.

[0041] In some embodiments, as shown in Figures 1 and 3, two guide plates 4 are provided at one bottom end of the tank 1. The two guide plates 4 are symmetrically arranged along the extension direction of the tank 1 (x direction as shown in Figure 1) and are respectively fixed to the side wall of the tank 1 and welded to the tank 1 to enhance stability. The guide plates 4 are located near the inlet 12 and can guide the rolled aluminum material 400 to move onto the tank 1 of the cooling device 100, so as to avoid the aluminum material 400 from shifting its position and preventing the cooling pipe 2 from effectively cooling down.

[0042] In some embodiments, as shown in Figures 1 to 3, each guide plate 4 has a V-shaped structure. The guide plate 4 is composed of a first plate 41 and a second plate 42. The first plate 41 and the second plate 42 are integrally formed. The first plate 41 has a preset tilt angle relative to the second plate 42. The tilt angle can be 100° or 140°, which can be adaptively set according to the required cross-sectional size of the aluminum material 400. As long as the aluminum material 400 can be guided through, this application does not impose too many restrictions on this.

[0043] In some embodiments, referring again to Figures 1 to 3, two limiting members 5 are provided on the tank 1. The two limiting members 5 are located on the side of the tank 1 away from the guide plate 4, that is, the two limiting members 5 are located near the outlet 12. The limiting members 5 are used to limit the position of the aluminum material 400, so that it can be accurately conveyed to the rod retractor 500 for subsequent operations. Each limiting member 5 has a triangular structure. At least one inclined surface of the limiting member 5 has a preset angle with the side wall surface of the tank 1. The preset angle can be adaptively adjusted as needed to limit the position of aluminum materials 400 with different cross-sectional sizes. In this regard, no further restrictions are imposed in this application.

[0044] In some embodiments, as shown in FIG3, the main pipe 21 includes an L-shaped guide pipe 210 and a storage pipe 211. One end of the L-shaped guide pipe 210 has an inlet 2101 and is connected to an emulsion device, which provides emulsion to the cooling pipe 2. The other end is connected to the storage pipe 211. The emulsion flows into the storage pipe 211 through the guide pipe 210 for subsequent spraying. The cooling pipe 2 is also provided with a plurality of branch pipes 22 spaced apart along the axial direction of the main pipe 21 (x direction as shown in FIG3) to ensure uniform cooling and lubrication of the aluminum material 400 surface. The first end 220 of the plurality of branch pipes 22 is connected to the storage pipe 211, and the second end 221 is connected to the side wall of the tank 1. During the conveying of the aluminum material 400, the emulsion device provides emulsion to the main pipe 21. The emulsion is collected into the storage pipe 211 through the inlet 2101, and then the plurality of branch pipes 22 make the emulsion enter the tank 1 evenly from multiple positions, thereby effectively cooling and lubricating the aluminum material 400. It should be noted that the nozzle angle of the branch pipe 22 can be adjusted according to the conveying direction of the aluminum material 400 to ensure that the emulsion can be accurately sprayed onto the surface of the aluminum material 400, so as to prevent emulsion waste or insufficient cooling. In addition, the number of branch pipes 22 can be 6 or 8, etc., which can be adapted to the length of the tank 1. This will not be elaborated in detail in this application.

[0045] In some embodiments, as shown in Figures 3 to 5, a drainage trough 6 is provided between the bottom and sidewall of the tank 1. The drainage trough 6 can effectively collect excess emulsion for subsequent centralized processing. The drainage trough 6 extends along the conveying direction of the aluminum material 400 (x direction as shown in Figure 3). In one example, as shown in Figures 4 and 5, the bottom of the drainage trough 6 has a drain outlet 61. During use, after the emulsion is sprayed onto the aluminum material 400, the excess emulsion flows into the drainage trough 6 and can flow into the collection box through the drain outlet 61 for subsequent centralized processing. At the same time, it ensures the cleanliness of the inside of the cooling device 100, so that the emulsion does not accumulate at the bottom of the tank 1, reducing the risk of dirt or corrosion inside the device, thereby enhancing the service life of the device and protecting the environment.

[0046] As shown in Figure 6, this application provides a continuous rolling mill. Aluminum material 400 is rolled into the required shape, thickness or width by multiple rolling processes of a multi-pass rolling mill 300. The continuous rolling mill includes a machine body 200 and a multi-pass rolling mill 300 mounted on the machine body 200, as well as a cooling device 100 as described above. The cooling device 100 is located on one side of the multi-pass rolling mill 300 and is detachably connected to the machine body 200. This ensures that when maintenance, replacement or cleaning is required during production, operators can easily disassemble, install and replace the device, thereby increasing the flexibility and maintainability of the equipment and reducing production downtime.

[0047] The working principle of the cooling device and continuous rolling mill disclosed in this application is as follows:

[0048] As shown in Figures 1 to 6, firstly, the raw metal material (e.g., trapezoidal aluminum billet) enters the mill body 200 of the continuous rolling mill through the conveying system. At this time, the raw metal material is at a high temperature and is rolled through three rolling mills 300. Each rolling mill 300 gradually reduces the thickness of the raw metal material and increases its length by adjusting the spacing and speed of the rolls to achieve the required aluminum material 400 (e.g., aluminum rod).

[0049] After multiple rolling passes, the pre-formed aluminum material 400 is guided into the tank 1 through the inlet 11 by the guide plate 4 and continues to be conveyed. At the same time, multiple branches 22 of the cooling pipe 2 spray emulsion evenly onto the surface of the aluminum material 400 for cooling and lubrication. The cooled aluminum material 400 is conveyed to the take-up machine 500 through the outlet 12 by the roller assembly 3. Under the dual action of the emulsion and the rollers 33 on the roller assembly 3, the quality of the aluminum material 400 can be ensured, and cracking, oxidation or deformation can be avoided. At this time, the temperature of the aluminum material 400 has dropped to the appropriate temperature range and the shape is fixed, and it can be further processed as needed (such as cutting, packaging, etc.).

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
