Description

Technical Field

[0001] The utility model relates to the technical field of metal plate processing equipment, in particular to an aluminum plate bending mechanism capable of accurately controlling the angle. Background Art

[0002] An aluminum plate is a plate made of aluminum. Its relatively small density makes the aluminum plate light in weight, convenient for handling and installation. Aluminum will also form a dense oxide film in the air, which can effectively prevent the aluminum plate from being corroded, making it have good corrosion resistance. Moreover, the aluminum plate is easy to process and form, and can be made into products of various shapes and sizes through processes such as stamping, bending, and stretching. During the aluminum plate processing, a bending mechanism is needed to perform bending treatment on it;

[0003] An aluminum plate bending mechanism is a mechanical device for bending aluminum plates. When in use, the aluminum plate is placed on the lower die of the bending mechanism. By setting the bending angle and other parameters through the control system, the power system drives the upper die to move downward, and together with the lower die, applies pressure to the aluminum plate, causing the aluminum plate to undergo plastic deformation, thereby achieving bending;

[0004] However, during the use of marine equipment, usually only aluminum plates with a single angle can be folded. To adjust the bending angle, other auxiliary tools need to be used or secondary processing is required. This not only increases the complexity and time cost of production, but also reduces the overall production efficiency. Therefore, an aluminum plate bending mechanism capable of accurately controlling the angle is proposed to solve the above problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1 and Figure 3 An embodiment provided by the present utility model: An aluminum plate bending mechanism capable of precisely controlling the angle, including a protective frame 2. A motorized telescopic plate 13 is fixedly connected to the top of the protective frame 2. The output end of the motorized telescopic plate 13 is fixedly connected to a bending head 14. A two-way cylinder 3 is fixedly connected to the bottom of the inner wall of the protective frame 2. Connecting blocks 4 are fixedly connected to both output ends of the two-way cylinder 3. A first rack 5 is fixedly connected to one side of each connecting block 4. A second gear 7 is arranged at the bottom of one of the first racks 5. The one first rack 5 and the second gear 7 are meshed with each other. A first gear 6 is arranged at the top of the other first rack 5. The other first rack 5 and the first gear 6 are meshed with each other. A second bending plate 10 is fixedly connected to the outer wall of the first gear 6. A first bending plate 9 is fixedly connected to the outer wall of the second gear 7. A fixing assembly is arranged inside the protective frame 2 and is used for fixing the plate. The fixing assembly includes a workbench 22. The bottom of the workbench 22 is fixedly connected to the bottom of the inner wall of the protective frame 2. A limiting post 8 is fixedly connected to the inside of the second gear 7. The outer wall of the limiting post 8 is fixedly connected to the inside of the first gear 6. One end of the limiting post 8 is slidably connected to the inside of the protective frame 2. A plurality of fixing blocks 11 are fixedly connected to the outer walls of the first bending plate 9 and the second bending plate 10. A slide bar 12 is fixedly connected to the inside of each fixing block 11. The outer wall of the slide bar 12 is slidably connected to the inside of the protective frame 2.

[0033] Specifically, during the actual use of the device, first start the motorized telescopic plate 13, and its output end drives the bending head 14 to move, starting to perform extrusion operations on the plate. At the same time, start the two-way cylinder 3, and the output ends on both sides thereof start to drive the first racks 5 on one side of the connecting blocks 4 to move. When the two first racks 5 move in opposite directions, a strong force will be generated, thereby driving the first gear 6 and the second gear 7 to rotate in opposite directions. The reverse rotation of the first gear 6 and the second gear 7 further drives the first bending plate 9 and the second bending plate 10 to move. Driven by the gears, the first bending plate 9 and the second bending plate 10 fold towards the opposite sides of the two sides of the plate. At the same time, the first bending plate 9 and the second bending plate 10 will drive the slide bars 12 to slide through the inside of the protective frame 2 through the fixing blocks 11, thereby enhancing the stability during the rotation of the first bending plate 9 and the second bending plate 10, and finally achieving the purpose of controlling the bending angle of the plate, solving the problem that traditional devices can only fold the aluminum plate at a single angle and are difficult to meet actual requirements, simplifying the production process, and improving the production efficiency of the device.

[0034] Reference Figure 2 and Figure 4 Figure 4 , a working bin 1 is fixedly connected to the bottom of the protective frame 2, a bottom box 21 is fixedly connected to the bottom of the working bin 1, a motor 15 is fixedly connected to the bottom of the inner wall of the protective frame 2, a third gear 16 is fixedly connected to the output end of the motor 15, second racks 17 are arranged on both sides of the third gear 16, the third gear 16 meshes with the second racks 17, clamping plates 18 are fixedly connected to the outer walls of both second racks 17, a plurality of limiting bars 19 are slidably connected inside the clamping plates 18, fixing plates 20 are fixedly connected to both ends of the limiting bars 19, one end of the limiting column 8 is slidably connected to the top of one fixing plate 20, and the bottom of the fixing plate 20 is fixedly connected to the bottom of the inner wall of the protective frame 2.

[0035] Specifically, during the process of fixing the plate, first place the plate to be processed on the top of the workbench 22. At this time, the workbench 22 provides a stable support plane for the plate. At the same time, the inside of the workbench 22 is hollow to reserve a bending space for the plate. Then start the motor 15. The output end of the motor 15 drives the third gear 16 to rotate, thereby driving the second racks 17 on both sides to move towards the opposite side. During this process, the clamping plates 18 also slide smoothly on the outer walls of the limiting bars 19 synchronously. The limiting bars 19 limit and guide the movement of the clamping plates 18. When the clamping plates 18 are driven by the second racks 17, they will generate a squeezing force on both sides of the plate to fix the plate, achieving the purpose of specifically fixing plates of different sizes and specifications, solving the problem that traditional equipment can only fix aluminum plates of a single size. When it is necessary to fix aluminum plates of other sizes, it is necessary to replace the fixing components, increasing the complexity of equipment fixing, and improving the fixing efficiency of the equipment for aluminum plates.

[0036] Working principle: During the use of the equipment, the output end of the electric telescopic plate 13 drives the folding head 14 to move to the surface of the plate and squeeze it. At the same time, start the double-acting cylinder 3. The output ends on both sides of the double-acting cylinder 3 drive the first rack 5 on one side of the connecting block 4 to move. When the two first racks 5 move in opposite directions, they will drive the first gear 6 and the second gear 7 to rotate in opposite directions, thereby driving the first bending plate 9 and the second bending plate 10 to move, folding both sides of the plate towards the opposite side to achieve the purpose of controlling the bending angle of the plate. During the process of fixing the plate, place the plate on the top of the workbench 22, and then start the motor 15. The output end of the motor 15 drives the third gear 16 to rotate, thereby driving the second racks 17 on both sides to move towards the opposite side. During this process, the clamping plates 18 also slide on the outer walls of the limiting bars 19 synchronously. The limiting bars 19 limit and guide the movement of the clamping plates 18. When the limiting bars 19 move to both sides of the plate, the squeezing force of the limiting bars 19 on both sides of the plate is used to achieve the purpose of specifically fixing different plates.
