Description

Technical Field

[0001] This utility model relates to the field of double-zero aluminum foil rolls, and more particularly to an ultra-high hardness wide double-zero aluminum foil roll. Background Technology

[0002] The ultra-high hardness wide-width double-zero aluminum foil roll is a cold rolling roll specifically designed for rolling double-zero aluminum foil with a thickness of only 0.005-0.009 mm. It has extremely high hardness, with the roll body hardness reaching HSD102-104, which is sufficient to withstand the high pressure during the rolling process of double-zero aluminum foil, ensuring the stability of the rolling process and the quality of the aluminum foil. In addition, its hardened layer depth is large, reaching or exceeding 25 mm, ensuring that the surface and interior of the roll have good hardness and wear resistance, effectively extending the service life of the roll. The hardness uniformity of the roll is also extremely excellent, controlled within HSD±0.5, thereby ensuring the uniformity of aluminum foil thickness during the rolling process and effectively avoiding aluminum foil thickness deviation caused by uneven roll hardness.

[0003] The inventors of this application have discovered the following problems during practical use:

[0004] Currently, some ultra-high hardness wide-width double-zero aluminum foil rolls are designed with a solid structure. Although the structure is sturdy, the weight is relatively heavy, which not only increases the difficulty and cost of transportation, but also makes maintenance more inconvenient and requires more manpower and resources. On the other hand, rolls with a hollow structure reduce weight and are easier to transport and install, but because they are hollow inside, they may be prone to bending and deformation when subjected to high rolling pressure, which affects the rolling accuracy and the quality of aluminum foil, and may even lead to roll damage, increasing production costs and maintenance difficulty.

[0005] Therefore, it is necessary to provide an ultra-high hardness wide-width double-zero aluminum foil roll to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is that solid structure rolls are heavy, inconvenient to transport and maintain, and hollow structure rolls are prone to bending deformation when subjected to large rolling pressure, which affects rolling accuracy and aluminum foil quality, and may even lead to roll damage. In view of the above-mentioned defects of the prior art, an ultra-high hardness wide-width double zero aluminum foil roll is provided.

[0007] To achieve the above objectives, the technical solution of this utility model is: an ultra-high hardness wide-width double-zero aluminum foil roll, comprising a roll, the roll comprising a roll body, the roll body having an installation groove inside, the installation groove having a lightweight mechanism inside, the lightweight mechanism comprising a main skeleton, the main skeleton being disposed at the axis of the roll body, the inner wall of the roll body having two inner skeletons, and the inner skeletons being connected by a spiral auxiliary rib, the inner skeletons being connected to the main skeleton by a reinforcing layer, and the cross-section of the reinforcing layer having multiple irregularly arrayed honeycomb grooves.

[0008] By adopting the above technical solutions, the rolls are made lightweight while maintaining high strength, thereby improving rolling efficiency and stability.

[0009] Furthermore, the lightweight structure is made of aluminum alloy.

[0010] By adopting the above technical solutions, the lightweight mechanism is both lightweight and robust, further improving the performance of the rolls.

[0011] Furthermore, the outer surface of the roller is coated with a diamond coating, and the roller as a whole is arranged in a columnar structure.

[0012] By adopting the above technical solution, the diamond coating possesses extremely high hardness and wear resistance, effectively resisting the wear of aluminum foil on the rolls and extending the rolls' service life. Simultaneously, the columnar structure makes the rolls more stable during the rolling process.

[0013] Furthermore, a first mounting roller and a second mounting roller are respectively provided on both sides of the roller body.

[0014] By adopting the above technical solutions, the installation of the rolls becomes more convenient, and they can be better coordinated with other equipment such as transmission equipment and support equipment, thereby improving the overall efficiency of the rolling production line.

[0015] Furthermore, the roll is made of high-chromium alloy, the first mounting roll is a drive roll, and the second mounting roll is a support roll.

[0016] By adopting the above technical solutions, high-chromium alloys have excellent wear resistance and corrosion resistance, enabling rolls to maintain good performance even in harsh working environments.

[0017] Furthermore, the first mounting roller has a gear-like structure and meshes with an external rotating device.

[0018] By adopting the above technical solutions, the transmission becomes more reliable, ensuring that the rolls maintain a stable speed and torque during the rolling process, thereby improving the rolling accuracy and efficiency.

[0019] Compared with related technologies, the ultra-high hardness wide-width double-zero aluminum foil roll provided by this utility model has the following beneficial effects:

[0020] This invention provides an ultra-high hardness wide-width double-zero aluminum foil roll. By incorporating a lightweight mechanism, inner skeleton, spiral auxiliary ribs, reinforcing layer, honeycomb groove, and main skeleton, the lightweight mechanism, supported by the main and inner skeletons and reinforced by the spiral auxiliary ribs, ensures that the roll maintains sufficient structural strength and stability while reducing weight. This solves the problem of hollow rolls easily flexing and deforming under high rolling pressure, guaranteeing rolling accuracy and aluminum foil quality. Simultaneously, the reinforcing layer, similar to a corrugated cardboard structure, possesses excellent compressive and bending resistance, ensuring that the roll is less prone to flexing and deforming under high rolling pressure while reducing weight, thus guaranteeing rolling accuracy and aluminum foil quality. Therefore, this design reduces weight, lowers transportation difficulty and cost, enhances structural strength and stability, improves rolling accuracy and aluminum foil quality, and facilitates maintenance and replacement.

[0021] This invention provides an ultra-high hardness wide-width double-zero aluminum foil roll with a diamond coating. The diamond coating has extremely high wear resistance, enabling it to withstand friction and wear during the aluminum foil rolling process for extended periods. This wear resistance not only extends the roll's service life but also reduces surface defects on the aluminum foil caused by roll wear, thus improving the yield of the aluminum foil. Furthermore, diamond has excellent thermal conductivity, which can quickly conduct away the heat generated during rolling, reducing the temperature of the roll and aluminum foil. This thermal conductivity helps reduce the impact of thermal stress on the roll and aluminum foil, improving rolling stability and aluminum foil quality. Attached Figure Description

[0027] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0028] Example 1:

[0029] like Figures 1-4 As shown, an ultra-high hardness wide-width double-zero aluminum foil roll includes a roll 1, which includes a roll body 101. An installation groove 104 is formed inside the roll body 101. A lightweight mechanism 2 is disposed inside the installation groove 104. The lightweight mechanism 2 includes a main frame 205, which is located at the axis of the roll body 101. Two inner frames 201 are provided on the inner wall of the roll body 101, and a spiral auxiliary rib 202 connects the inner frames 201. A reinforcing layer 203 connects the inner frames 201 and the main frame 205, and the cross-section of the reinforcing layer 203 has multiple irregularly arrayed... The honeycomb groove 204, through the design of the mounting groove 104 inside the roll 1 and the installation of the lightweight mechanism 2 in the mounting groove 104, realizes the lightweight design of the roll. The main skeleton 205 in the lightweight mechanism 2 is located at the axis of the roll body 101. Together with the two inner skeletons 201 on the inner wall and the spiral auxiliary ribs 202 between them, as well as the reinforcing layer 203 between the inner skeleton 201 and the main skeleton 205 and the multiple irregular array honeycomb grooves 204 opened on its cross surface, it enhances the structural strength and stability of the roll, while reducing the weight and improving the rolling efficiency and energy utilization rate.

[0030] See Figure 3 , Figure 4 The lightweight mechanism 2 is made of aluminum alloy. The use of aluminum alloy in the lightweight mechanism 2 not only reduces the overall weight of the roll, but also takes advantage of the good machinability and corrosion resistance of aluminum alloy. This makes the lightweight mechanism 2 easy to manufacture and maintain while maintaining high strength, extending the service life of the roll and reducing production costs.

[0031] Example 2:

[0032] See Figure 1 , Figure 4 The outer surface of the roll body 101 is coated with a diamond coating 105. The roll body 101 has an overall columnar structure. The diamond coating 105 on the outer surface of the roll body 101 greatly improves the hardness and wear resistance of the roll, enabling the roll to resist the wear of aluminum foil during rolling and maintain surface smoothness, thereby improving the product quality of aluminum foil. At the same time, the columnar structure design of the roll body 101 makes the roll more uniformly stressed, enhancing the stability of rolling.

[0033] See Figure 3 , Figure 4The roll body 101 has a first mounting roll 102 and a second mounting roll 103 on both sides, which facilitates the installation and positioning of the roll. This design allows the roll to be more accurately connected to other equipment during installation, improving installation efficiency. It also facilitates the disassembly and maintenance of the roll, reducing maintenance costs.

[0034] See Figure 1 , Figure 2 The roll 1 is made entirely of high-chromium alloy. The first mounting roll 102 is the drive roll, and the second mounting roll 103 is the support roll. The high-chromium alloy material provides excellent wear resistance and corrosion resistance, allowing the roll to maintain good performance even in harsh working environments. The first mounting roll 102, as the drive roll, is responsible for transmitting power, while the second mounting roll 103, as the support roll, provides stable support. Their clear division of labor and seamless cooperation improve the overall efficiency and stability of the rolling production line.

[0035] See Figure 1 , Figure 4 The first mounting roll 102 has a gear-like structure and meshes with an external rotating device. This design makes the transmission more reliable and efficient. The gear-like structure ensures uniform torque transmission during the transmission process, avoiding a decrease in rolling accuracy due to unstable transmission. At the same time, the meshing design with the external rotating device allows for more flexible adjustment of the roll's speed and direction, meeting the needs of different rolling processes.

[0036] In practice, firstly, when the roll 1 is reproduced, the lightweight mechanism 2 is made of metal 3D printing technology. At this time, the main frame 205 of the lightweight mechanism 2 is aligned with the axis of the roll 1 to ensure that the two are concentric. The lightweight mechanism 2 is then placed smoothly into the mounting groove 104 of the roll 1.

[0037] Between the inner frame 201 of the lightweight mechanism 2 and the inner wall of the roll 1, some fasteners are installed to ensure the stability of the lightweight mechanism 2 in the roll 1. After installation, the position of the lightweight mechanism 2 in the roll 1 is adjusted to ensure that it is in the best working condition.

[0038] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0039] 1. By setting up lightweight mechanisms, inner skeletons, spiral auxiliary ribs, reinforcing layers, honeycomb grooves, and main skeletons, the weight of the rolls is reduced, the transportation difficulty and cost are lowered, the structural strength and stability of the rolls are enhanced, the rolling accuracy and the quality of aluminum foil are improved, and maintenance and replacement are facilitated.

[0040] 2. The design of the reinforcing layer is similar to that of corrugated paper, which has good compressive and bending resistance, ensuring that the rolls are not prone to bending deformation when subjected to large rolling pressure, thereby ensuring the stability of rolling and the quality of finished aluminum foil.

[0041] 3. The diamond coating provides extremely high wear resistance, enabling it to withstand friction and wear during the aluminum foil rolling process for extended periods. This extends the service life of the rolls, reduces surface defects on the aluminum foil caused by roll wear, and improves the yield of finished aluminum foil.

[0042] 4. The diamond coating also has good thermal conductivity, which can quickly conduct away the heat generated during the rolling process, reduce the temperature of the rolls and aluminum foil, help reduce the impact of thermal stress on the rolls and aluminum foil, and further improve the rolling stability and the quality of the aluminum foil.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
