Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing equipment technology, specifically to a multi-layer composite device for extremely thin metal strips. Background Technology
[0002] In high-end manufacturing fields such as electronics and information, aerospace, and new energy, ultra-thin metal strip multilayer composite materials have become key basic materials due to their unique mechanical properties, electrical and thermal conductivity, and corrosion resistance. The composite process for ultra-thin metal strip multilayer composite devices is mainly achieved through rolling, calendering, and other methods.
[0003] In the prior art, the composite device is equipped with two rollers. When the device is started, the two rollers rotate towards each other in a set direction, thereby forming a working area with specific pressure and motion tendency between the rollers. When the multilayer metal ultrathin strip is fed into this working area formed by the rollers, it will be subjected to pressure from the roller surface. Under this pressure, the metal ultrathin strip undergoes plastic deformation, and the atoms between the multilayer metals approach each other and diffuse, gradually realizing metallurgical bonding.
[0004] However, during the process of applying pressure to multi-layer ultra-thin metal strips to achieve composite, the surface of the metal strip is subjected to extrusion and friction, resulting in the generation of tiny debris or oxides that adhere to the surface of the roll. As the roll continues to rotate, impurities can easily become embedded in the gaps between the metal strips, thus affecting the composite effect of multi-layer ultra-thin metal strips. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example 1
[0024] Please see Figures 1 to 2 This utility model provides a technical solution: a multi-layer composite device for extremely thin metal strips, including a workbench 1, two support plates 2 are fixedly connected to the surface of the workbench 1, two rollers 3 are rotatably connected to the surface of the support plates 2, a cleaning scraper 10 is attached to the surface of the rollers 3, two fixed plates 11 are fixedly connected to the surface of the cleaning scraper 10, two movable plates 5 are slidably connected to the surface of the support plates 2, a connecting plate 9 is fixedly connected to the surface of the movable plates 5, and the connecting plate 9 is inserted into the surface of the fixed plate 11.
[0025] A cleaning scraper 10 is installed on the surface of the roll 3 to remove residual impurities, preventing impurities from mixing with the ultra-thin metal composite strip and improving the quality of the composite product. Through the cooperation of the spring 7, the moving plate 5, and the center rod 6, the cleaning scraper 10 can adapt to changes in the surface of the roll 3 and always maintain contact with the roll 3, improving the cleaning effect. Through the cooperation of the extension plate 12, the elastic block 13, and the limiting block 14 on the connecting plate 9 with the fixing plate 11, the cleaning scraper 10 can be quickly installed and removed, shortening equipment maintenance time and improving production efficiency.
[0026] Example 2
[0027] Please see Figures 1 to 4 Based on the first embodiment, in order to clean the impurities on the surface of the roll 3, two sliding grooves 4 are opened on the surface of each support plate 2. The sliding grooves 4 are square grooves. The sliding grooves 4 provide a sliding track for the moving plate 5, limiting its movement direction so that it can only slide along the length direction of the sliding grooves 4 on the surface of the support plate 2, ensuring that the moving plate 5 drives the cleaning scraper 10 to move smoothly.
[0028] A central rod 6 is fixedly connected between the two ends of the surface of the sliding groove 4. The central rod 6 provides mounting support for the spring 7, so that the spring 7 can be stably sleeved on its surface to play its role. The central rod 6 has a cylindrical structure, and the spring 7 is sleeved on the surface of the central rod 6. The spring 7 is in a stretched state. The spring 7 provides a pulling force to the moving plate 5 toward the roller 3, so that the moving plate 5 drives the cleaning scraper 10 to always be in close contact with the surface of the roller 3. When the diameter of the roller 3 changes due to factors such as wear and temperature changes, the spring 7 automatically adjusts the position of the moving plate 5 through its own expansion and contraction deformation, so as to achieve adaptive adjustment of the contact degree between the cleaning scraper 10 and the surface of the roller 3.
[0029] The movable plate 5 has a square plate structure. The movable plate 5 has a central hole 15 on both sides of its surface. The central hole 15 is a circular hole. The central rod 6 passes through the central hole 15. One end of the spring 7 is fixedly connected to the surface of the movable plate 5, and the other end of the spring 7 is fixedly connected to the surface of the sliding groove 4.
[0030] Example 3
[0031] Please see Figures 1 to 5 Based on Embodiment 2, in order to replace the cleaning scraper 10, the connecting plate 9 has a square plate structure. The connecting plate 9 provides an installation base for the extension plate 12, ensuring that the extension plate 12 and the moving plate 5 are fixedly connected. The extension plate 12 is fixedly connected to one end surface of the connecting plate 9. The extension plate 12 has a square plate structure. The extension plate 12 is used to realize the initial docking of the connecting plate 9 and the fixed plate 11, and provides a channel and support for the engagement of the limiting block 14 and the fixed plate 11, so that the cleaning scraper 10 can establish a connection relationship with the moving plate 5.
[0032] The surface of the extension plate 12 has a telescopic groove 16, which provides movement space for the elastic block 13 and the limiting block 14. When the limiting block 14 is squeezed, it can drive the elastic block 13 to retract in the telescopic groove 16, so as to pass smoothly through the limiting hole 8 of the fixed plate 11. When the limiting block 14 passes the edge of the limiting hole 8, the elastic block 13 restores its deformation and pushes the limiting block 14 out, so as to achieve the locking and fixing with the fixed plate 11.
[0033] Elastic blocks 13 are fixedly connected to the center of both sides of the telescopic groove 16, while the other parts are in contact with the surface of the elastic blocks 13. The elastic blocks 13 use their own elastic deformation characteristics to provide telescopic power for the limiting blocks 14. A limiting block 14 is fixedly connected to each of the two ends of the elastic block 13.
[0034] The limiting block 14 is in a square block structure. The surfaces of the two ends of the limiting block 14 away from each other are provided with inclined surfaces, which facilitate automatic contraction and entry into the telescopic groove 16 when being pressed during insertion. After being inserted in place, it pops out under the action of the elastic block 13 and is clamped on the surface of the fixed plate 11, preventing the connecting plate 9 from separating from the fixed plate 11, ensuring that the cleaning scraper 10 is firmly installed on the moving plate 5. The fixed plate 11 is in a "C"-shaped plate structure. A limiting hole 8 is formed on the surface of one end of the fixed plate 11. The limiting hole 8 is a square hole. The extension plate 12 passes through the surface of the limiting hole 8 and presses the limiting block 14 against the surface of the fixed plate 11.
[0035] During actual use, when the device is started for multi-layer compounding of ultra-thin metal strips, the rolling rolls 3 start to rotate towards each other, and the multi-layer ultra-thin metal strips are fed between the rolling rolls 3 for compounding processing. At the same time, under the pre-tightening force of the spring 7, the cleaning scraper 10 closely adheres to the surface of the rolling roll 3. As the rolling roll 3 rotates, impurities on the surface of the rolling roll 3 are removed in a timely manner. When the diameter of the rolling roll 3 changes due to factors such as wear and temperature change on the surface of the rolling roll 3 or the cleaning scraper 10 is worn after long-term use, the moving plate 5 can slide along the sliding groove 4 on the central rod 6, and the spring 7 gradually returns to its original state from the stretched state, enabling the cleaning scraper 10 to always maintain a good fitting state with the rolling roll 3 and ensuring the cleaning effect.
[0036] When it is necessary to disassemble and replace the cleaning scraper 10, the operator only needs to press the limiting block 14 by hand to make it retract into the telescopic groove 16, and then pull out the extension plate 12 on the surface of the connecting plate 9 from the limiting hole 8 of the fixed plate 11, and then the cleaning scraper 10 can be removed. The operation is simple and convenient. When installing a new cleaning scraper 10, align the extension plate 12 and insert it into the limiting hole 8. The limiting block 14 automatically contracts under the action of the inclined surface. When the extension plate 12 is completely inserted, the limiting block 14 pops out under the action of the elastic block 13 and is clamped on the surface of the fixed plate 11, completing the rapid installation of the cleaning scraper 10.
[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
