Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to a hot rolling composite device for aluminum composite plates. Background Technology
[0002] Aluminum composite panels, as a high-performance and widely used new type of composite material, are extensively used in building curtain walls, transportation, electronic equipment, and other fields due to their lightweight, high strength, corrosion resistance, and good decorative effect. Hot-rolling composite technology is one of the key processes in the manufacturing of aluminum composite panels. By bonding aluminum layers with different properties under high temperature and pressure conditions, a tight bond and performance optimization of the materials are achieved, thereby meeting the requirements for high strength and high added value.
[0003] Currently, most common hot rolling equipment for aluminum composite panels on the market uses a single roll or multiple sets of rolls to apply the same pressure for hot rolling. While these devices are relatively simple in structure and easy to operate, they have significant shortcomings. First, the single-pressure hot rolling method cannot meet the differentiated pressure requirements of different areas of the aluminum composite panel throughout the hot rolling process, resulting in uneven stress on the sheet and easily causing localized insufficient pressure or overload, affecting composite quality and product performance. Second, rolls under uniform pressure often struggle to gradually apply pressure to the aluminum composite panel, leading to unreasonable stress distribution during hot rolling. This can easily cause problems such as warping, delamination, or internal stress concentration in the sheet, reducing product consistency and stability. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a hot-rolling composite device for aluminum composite plates, thereby solving the aforementioned problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a hot-rolling composite device for aluminum composite plates, comprising an outer casing, which is open from front to back. Several lower rollers are sequentially installed from front to back inside the bottom of the outer casing, and an upper roller is positioned directly above each lower roller. Several lower pressing components, each connected to an upper roller, are sequentially installed from front to back on the top of the outer casing. The downward pressure of the pressing components increases sequentially from front to back. Each pressing component specifically includes a mounting frame, a lifting platform, an electric hydraulic cylinder, and a clamping spring. The mounting frame serves as the upper roller mounting structure. The electric hydraulic cylinder is mounted on the top of the outer casing. The lifting platform is connected to the end of the piston rod of the electric hydraulic cylinder. Three clamping springs are correspondingly installed at the left and right ends and the center position between the mounting frame and the lifting platform.
[0008] As a preferred technical solution of this utility model, the downward pressure of the electric hydraulic cylinders inside the several pressing parts increases sequentially.
[0009] As a preferred technical solution of this utility model, telescopic connecting rods are installed on both the left and right sides of the center between the mounting frame and the lifting platform.
[0010] As a preferred technical solution of this utility model, guide columns are installed at the left and right ends of the top of each lifting platform, and the guide columns on both sides are slidably connected to the top of the outer casing.
[0011] As a preferred technical solution of this utility model, several vertically distributed guide grooves are sequentially opened on the left and right side walls inside the outer casing from front to back, and each guide groove is equipped with a guide component that cooperates with the lifting operation of the mounting frame.
[0012] As a preferred technical solution of this utility model, the guide assembly includes a guide post installed inside the guide groove and a guide sleeve slidably sleeved on the guide post, wherein the inner wall of the guide sleeve is connected to the outer wall of the mounting bracket on the same side.
[0013] Compared with the prior art, this utility model provides a hot rolling composite device for aluminum composite plates, which has the following beneficial effects:
[0014] By achieving progressively increasing pressing pressure, the aluminum composite panel is ensured to be subjected to uniform and gradual pressure during hot rolling, effectively avoiding local overload or underload, thereby significantly improving the uniformity of hot rolling effect and the overall quality of the panel.
[0015] By precisely controlling the lifting platform with an electric hydraulic cylinder, the pressure of each roll increases progressively, improving the uneven pressure distribution problem in the traditional single-pressure hot rolling method and enhancing the density and bonding performance of the sheet during hot rolling.
[0016] The auxiliary function of the compression spring and the stable guiding design of the guide structure ensure the stable operation of the rolls during the step-by-step pressurization process, effectively reducing deviation and vibration, and improving the working stability and production efficiency of the equipment.
[0017] The progressively increasing hot rolling process can better control the stress distribution during hot rolling, reduce plate deformation and stress concentration, improve the surface quality and internal structure uniformity of aluminum composite panels, and thus ensure that the final product has better performance indicators.
[0018] The use of multi-stage pressure gradient hot rolling technology helps to achieve higher production efficiency and better product quality, reduce defect rate, extend equipment service life, and reduce maintenance costs.
[0019] In summary, this hot-rolling composite unit, through its innovative design and progressively increasing pressure hot rolling technology, effectively overcomes the shortcomings of traditional single-pressure hot rolling, significantly improving the hot rolling effect of aluminum composite plates. Its multi-point, multi-stage pressure control system ensures uniform stress on the plate throughout the hot rolling process, resulting in higher quality stability and superior performance. The equipment has a rational structure, a stable and reliable guiding system, and precise operation control, providing a strong guarantee for achieving high-quality, high-efficiency aluminum composite plate production. The application of this technology not only optimizes the hot rolling process but also has promising prospects for widespread adoption, contributing to the technological and industrial upgrading of the aluminum processing industry and meeting the growing market demand for high-quality aluminum composite plates.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.
[0029] It should be noted that if the utility model embodiment involves directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0030] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them.

[0031] Please see Figure 1-4 A hot-rolling composite device for aluminum composite panels includes an outer casing 1. The outer casing 1 has a through-structure, with several lower rollers 2 arranged sequentially from front to back at its bottom. An upper roller 3 is positioned directly above each lower roller 2. Several lower pressure members 4 are sequentially installed from front to back at the top of the outer casing 1. Each lower pressure member 4 is connected to a corresponding upper roller 3, and the downward pressure of each lower pressure member 4 increases progressively from front to back. This allows the aluminum composite panel to undergo gradual hot rolling after entering the outer casing 1, resulting in a more uniform hot rolling effect.
[0032] Specifically, each pressing component 4 includes a mounting frame 41, a lifting platform 42, an electric hydraulic cylinder 43, and a clamping spring 44. The mounting frame 41 serves as the mounting support structure for the upper roll 3, ensuring the stable positioning of the upper roll. The electric hydraulic cylinder 43 is fixedly installed on the top of the outer casing 1, with its piston rod end docking with the lifting platform 42. The lifting platform 42 achieves up-and-down lifting movements through the drive of the electric hydraulic cylinder 43. Three clamping springs 44 are provided, respectively installed at the left and right ends and the center position between the mounting frame 41 and the lifting platform 42, to provide auxiliary clamping force and ensure stability and uniformity during the pressing process.
[0033] The downward pressure applied by the electric hydraulic cylinders 43 inside each pressing component 4 increases sequentially, forming a pressure gradient from front to back, in order to adapt to the pressing requirements of different areas of the aluminum composite plate during hot rolling.
[0034] Telescopic connecting rods 45 are provided at the center and on the left and right sides between the mounting frame 41 and the lifting platform 42, respectively, to connect and adjust the relative position between the two, thereby enhancing the rigidity and coordination of the overall structure.
[0035] Guide columns 46 are installed at both ends of the top of the lifting platform 42. The guide columns 46 slide through the guide holes at the top of the outer casing 1 to ensure the stable guidance of the lifting platform 42 during the lifting process and prevent it from shifting laterally.
[0036] Several vertically distributed guide grooves 11 are sequentially formed on the left and right side walls inside the outer casing 1, from front to back. Each guide groove 11 contains a guide assembly 12, which includes a guide post 121 installed inside the guide groove 11 and a guide sleeve 122 slidably sleeved on the guide post 121. The guide sleeve 122 is connected to the outer wall of the mounting frame 41 on the same side through its inner wall, so as to realize stable guidance during the lifting and lowering operation of the mounting frame 41, ensuring its smooth vertical movement and avoiding lateral swaying.
[0037] The working process of the hot rolling composite device for aluminum composite plates is as follows: The aluminum composite plate enters the outer casing 1 from the front end and passes sequentially through a rolling zone composed of several sets of upper and lower rollers 2 and 3. Each set of upper rollers 3 is fixed by a mounting frame 41, and the corresponding lower pressure component 4 applies progressively increasing downward pressure. Specifically, the electric hydraulic cylinder 43 drives the lifting platform 42 to move up and down, and the upper rollers 3 rise and fall accordingly, pressing the aluminum composite plate. The pressure spring 44 provides auxiliary pressure to ensure uniform and stable pressing. As the aluminum composite plate passes through each section of rollers, it is subjected to a gradually increasing pressure gradient from front to back, achieving progressively increased pressure during hot rolling, ultimately ensuring uniform hot rolling effect and stable quality.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
