Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate production, and particularly relates to a straightening device for large-bend aluminum plates. Background Art

[0002] An aluminum plate straightening device is a device used to remove the bending, waviness and other forms of unevenness generated during the production, processing or storage of aluminum plates, and ensure the geometric accuracy and surface quality of the final product.

[0003] In the related art, for the straightening of aluminum plates, a relatively common method is to apply continuous bending force to the aluminum plates through a series of upper and lower staggered pressure rollers, and gradually eliminate the residual stress and surface unevenness inside the plates.

[0004] However, this method has poor flexibility. Especially for aluminum plates with a large initial bending degree, dynamic adjustment cannot be achieved. Straightening directly through the pressure rollers at fixed positions will not only cause scratches and indentations on the surface, but even form cracks inside the aluminum plates. In severe cases, it will damage the integrity and mechanical properties of the aluminum plates, and will also leave residual deformation, or over-straighten, causing reverse bending or wavy deformation of the material, affecting the flatness and dimensional accuracy of the final product. Summary of the Invention

Detailed implementation manners

[0024] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0025] The large - curvature aluminum plate straightening device of the embodiments of the present utility model will be described below with reference to the drawings.

[0026] As Figure 1 and Figure 2 shown, the large - curvature aluminum plate straightening device of the embodiments of the present utility model may include a transmission device 100, side plates 200, a rough straightening device 300, and a pressure roller 400.

[0027] Among them, the transmission device 100 is arranged on two opposite side plates 200, and the rough straightening device 300 and the pressure roller 400 are sequentially arranged above the transmission end of the transmission device 100 along the feeding direction.

[0028] It should be noted that both the rough straightening device 300 and the pressure roller 400 are installed between the two side plates 200. The aluminum plate passes through between the rough straightening device 300 and the transmission device 100 and exits between the pressure roller 400 and the transmission device 100 to complete the straightening process.

[0029] As Figure 3 shown, the rough straightening device 300 includes a lifting frame 310, a hydraulic cylinder 320, a first roller 330, a lifting structure 340 and a second roller 350.

[0030] Among them, the lifting frame 310 is slidably arranged between two side plates 200, the hydraulic cylinder 320 is arranged on the side plates 200, and the telescopic end of the hydraulic cylinder 320 is connected to the lifting frame 310.

[0031] It should be noted that, to improve the lifting stability of the lifting frame 310, there can be two hydraulic cylinders 320, which are relatively arranged on both sides of the lifting frame 310.

[0032] The lifting structure 340 is arranged on the lifting frame 310, and the first roller 330 is rotatably arranged on the lifting end of the lifting structure 340.

[0033] The second roller 350 is arranged behind the first roller 330 along the feeding direction and is installed on the lifting frame 310.

[0034] It can be understood that when the aluminum plate passes through between the rough straightening device 300 and the transmission device 100, it first passes through the first roller 330, and is transmitted to the lower part of the second roller 350 under the extrusion of the first roller 330 and the transmission device 100.

[0035] Specifically, when the relevant staff straighten the aluminum plate, first, the relevant staff adjust the rough straightening device 300 according to the flatness of the aluminum plate, that is, by driving the hydraulic cylinder 320, the telescopic end of the hydraulic cylinder 320 drives the lifting frame 310 to lift and lower, so that the first roller 330 and the second roller 350 reach the appropriate positions.

[0036] Then the relevant staff place the aluminum plate on the transmission device 100, and the aluminum plate passes through the first roller 330 and the second roller 350 in turn through the transmission device 100. Through the preliminary extrusion of the first roller 330 and the second roller 350, the bending degree of the aluminum plate becomes smaller, and then passes under the pressing roller 400. The pressing roller 400 performs the final straightening on the aluminum plate, avoiding the situation that the fixed pressing roller 400 directly presses down the aluminum plate, resulting in deformation, surface scratches and internal cracks of the aluminum plate.

[0037] When the bending degree at the front end of the aluminum plate is relatively large, the relevant staff can adjust the first roller 330 to rise through the lifting structure 340, so that there is a certain height difference between the heights of the first roller 330 and the second roller 350. Then the distances between the first roller 330, the second roller 350 and the pressing roller 400 and the transmission device 100 decrease in turn, so that the bent aluminum plate can be gradually straightened, making the straightening of the aluminum plate more delicate.

[0038] In an embodiment of the present utility model, as Figure 1 and Figure 3 shown, sliding portions 201 are respectively provided on two side plates 200, sliders 311 are respectively provided at both ends of the lifting frame 310, and the sliders 311 are slidably connected to the corresponding sliding portions 201.

[0039] It should be noted that when the lifting frame 310 is pushed by the hydraulic cylinder 320, the slider 311 slides within the sliding portion 201 to ensure the stability of the lifting frame 310 during lifting and lowering.

[0040] In addition, a cleaning brush 312 is provided on the lifting frame 310. The cleaning brush 312 can be provided on one side of the lifting frame 310 close to the feeding end, so that before the aluminum plate passes through the rough straightening device 300, the surface of the aluminum plate is brushed by the cleaning brush 312 to remove dust and debris.

[0041] Bearing seats 351 are respectively provided on both sides of the lifting frame 310, and both ends of the second roller 350 are rotatably provided on the corresponding bearing seats 351.

[0042] To clearly illustrate the previous embodiment, in an embodiment of the present utility model, the lifting frame 310 is a rectangular frame structure. Both the first roller 330 and the second roller 350 are located inside the lifting frame 310, and the bottoms of both the first roller 330 and the second roller 350 are lower than the bottom of the lifting frame 310.

[0043] It should be noted that through the design that the bottoms of both the first roller 330 and the second roller 350 are lower than the bottom of the lifting frame 310, it can be ensured that when the lifting frame 310 descends, the first roller 330 and the second roller 350 are in contact with the surface of the aluminum plate, avoiding the situation where the lifting frame 310 contacts the aluminum plate.

[0044] In an embodiment of the present utility model, as Figure 4 and Figure 5 shown, the lifting structure 340 includes a mounting frame 341, a connecting block 342, a threaded rod 343, and a handwheel 344.

[0045] Among them, the mounting frame 341 is provided on the lifting frame 310, the connecting block 342 is slidably provided inside the mounting frame 341, the threaded rod 343 is threadedly connected to the top of the mounting frame 341 and passes through the mounting frame 341 and is rotatably connected to the connecting block 342, and the handwheel 344 is provided on the top of the threaded rod 343.

[0046] Among them, the first roller 330 is rotatably provided on the connecting block 342.

[0047] It should be noted that when the relevant staff adjusts the height of the first roller body 330, the relevant staff can rotate the handwheel 344 to rotate the threaded rod 343, so that the threaded rod 343 drives the connecting block 342 to lift in the mounting frame 341, so as to adjust the height of the first roller body 330 connected to the connecting block 342.

[0048] In an embodiment of the present invention, the transmission device 100 includes a driving motor 110, a transmission roller 120 and a transmission structure 130.

[0049] Among them, a plurality of transmission rollers 120 are rotatably arranged between two side plates 200 in sequence, and two adjacent transmission rollers 120 are respectively connected by a transmission structure 130, and the output end of the driving motor 110 is connected to one of the transmission rollers 120.

[0050] As a possible case, the transmission structure 130 includes two synchronous pulleys and a synchronous belt. The two synchronous pulleys are coaxially arranged with two adjacent transmission rollers 120 respectively, and the synchronous belt connects the two synchronous pulleys.

[0051] It should be noted that the driving motor 110 can be fixed on the ground or the side plate 200 through a mounting seat and connected to one of the transmission rollers 120 through a belt. When the transmission device 100 is started, the driving motor 110 drives the transmission roller 120 connected thereto to rotate, and then the transmission roller 120 drives the adjacent transmission roller 120 to rotate synchronously through the transmission structure 130, so as to realize the synchronous rotation between a plurality of transmission rollers 120.

[0052] In summary, according to the large-bend aluminum plate straightening device of the embodiment of the present invention, the initial large-bend degree of the aluminum plate can be preliminarily straightened through the rough straightening device 300, so that the bending degree of the material is reduced before entering the pressure roller 400, avoiding excessive pressure on the aluminum plate, reducing the risk of surface scratches and internal cracks, protecting the integrity and surface quality of the aluminum plate, improving the overall straightening accuracy. In addition, through the liftable first roller body 330, fine adjustment can be further carried out for different degrees of bending of the aluminum plate.
