[0002] In modern industry, aluminum alloy profiles are widely used in construction, automobile manufacturing, rail transportation, aerospace, and many other industries due to their excellent properties such as lightweight, high strength, and corrosion resistance. As industries increasingly demand personalized and customized products, aluminum alloy profiles of different specifications and sizes are being used more and more frequently in production and processing. Among these processes, bending is one of the key steps in aluminum alloy profile forming, and its processing accuracy and efficiency directly affect the quality and performance of the final product.

[0003] Existing bending devices, such as the aluminum alloy profile bending device disclosed in CN208288720U, employ a straight beam placement frame fixed on a workbench, a lower pressure block located on top of the straight beam placement frame, and a drive structure that drives the lower pressure block. The aluminum profile is placed on the straight beam placement frame and then bent by stamping. The structure is simple and easy to operate. However, the straight beam placement frame is a fixed structure and cannot be adjusted in size. When bending profiles of different sizes is required, operators often need to replace the entire set of molds or perform large-scale disassembly and adjustment of the device. This not only consumes a lot of time and labor costs, reducing production efficiency, but may also lead to a decrease in the assembly accuracy of the device due to frequent component replacements, thereby affecting the accuracy of the bending process and causing problems such as profile bending angle deviation and surface damage. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-4 An aluminum alloy profile bending device includes a workbench 1 and a pressing component 2 fixedly installed on the top of the workbench 1. The pressing component 2 is a prior art used in the field described in this invention. It drives the pressing block to move down through a hydraulic cylinder to press and bend the aluminum profile, so it will not be described in detail.

[0016] A fixed plate 3 is fixedly connected to the front side of the pressing component 2, and a connecting plate 4 is fixedly connected to the bottom of the worktable 1. A screw 5 is rotatably connected inside the connecting plate 4. The screw 5 is rotatably connected to the connecting plate 4 through a bearing, which can ensure the stability of the screw 5 when rotating. The front end of the screw 5 passes through the outer wall of the connecting plate 4 and is slidably connected to a crank handle 6. The sliding connection between the crank handle 6 and the screw 5 can adopt a key connection combined with a sliding groove structure, which facilitates the disassembly and installation of the crank handle 6 and can transmit torque. The crank handle 6 is connected to a moving plate 7 through a gap adjustment structure. An adjustable limit component 8 that is adjusted according to the thickness of the aluminum profile is fixedly connected to one end of the fixed plate 3. The gap adjustment structure includes a limiting groove 9 on the top of the workbench 1. The limiting groove 9 has a T-shaped cross-section. A movable plate 10 is slidably connected inside the limiting groove 9. The bottom shape of the movable plate 10 is adapted to the limiting groove 9 to prevent the movable plate 10 from shifting during sliding. The movable plate 10 is threadedly connected to the screw 5. The movable plate 10 has a threaded hole that matches the screw 5. The bottom of the movable plate 10 is fixedly connected to the moving plate 7. The connection method can be welding or bolting to ensure the firmness of the connection. When the crank handle 6 is turned, the screw 5 rotates accordingly. Under the action of the thread, the movable plate 10 slides along the limiting groove 9, thereby driving the moving plate 7 to move synchronously, realizing the adjustment of the gap between the moving plate 7 and the fixed plate 3. An opening 11 is provided on the outer wall of the fixed plate 3. The length of the opening 11 is adapted to the movement range of the movable plate 7. A base plate 12 is fixedly connected to the opposite side of the movable plate 7. The thickness of the base plate 12 is slightly less than the height of the opening 11. The base plate 12 is slidably connected to the opening 11. During the movement of the movable plate 7, the base plate 12 slides along the opening 11, which can provide auxiliary support and guidance for the movable plate 7 and enhance the stability of the movable plate 7 during movement. A recessed panel 14 is fixedly connected to one side of the fixed plate 3. The recessed panel 14 can be made of high-strength alloy and its surface is polished to reduce friction with the profile. A notch 13 that matches the recessed panel 14 is opened at the middle of the outer wall of the movable plate 7. The depth of the notch 13 matches the thickness of the recessed panel 14. The recessed panel 14 and the notch 13 are slidably connected. The recessed panel 14 is located directly below the pressing component 2. The recessed panel 14 and the notch 13 cooperate to position the profile and ensure that the profile is in the correct position during the bending process. At the same time, the sliding connection between the two does not affect the adjustment of the movable plate 7. The adjustable limiting assembly 8 includes a limiting plate 15 fixedly connected to the left side of the fixed plate 3. The limiting plate 15 and the fixed plate 3 can be integrally formed or bolted together. A sliding rod 17 is fixedly connected to the top of the limiting plate 15. There are two sliding rods 17, symmetrically arranged on both sides of the limiting plate 15. An upper pressure plate 16 is slidably connected to the sliding rod 17. The upper pressure plate 16 has a sliding hole that matches the sliding rod 17. A capped screw 18 is rotatably connected to the top of the limiting plate 15. The capped screw 18 is connected to the limiting plate 15 through a bearing. The capped screw 18 passes through the outer wall of the upper pressure plate 16 and is threaded. The upper pressure plate 16 has a threaded hole that matches the capped screw 18. By rotating the capped screw 18, the upper pressure plate 16 can move up and down along the sliding rod 17 under the guidance of the sliding rod 17, thereby adjusting the distance between the upper pressure plate 16 and the limiting plate 15 according to the thickness of the profile. The bottom of the upper pressure plate 16 is provided with a buffer groove 19. There are multiple buffer grooves 19, which are evenly distributed on the bottom of the upper pressure plate 16. A spring 20 is fixedly connected to the inner wall of the buffer groove 19. The spring 20 is made of high-strength spring steel and has good elastic recovery performance. A compression plate 21 is slidably connected to the inner wall of the buffer groove 19. The compression plate 21 can be made of rubber or polyurethane and has a certain elasticity. The end of the spring 20 away from the capped screw 18 is fixedly connected to the compression plate 21. When the profile is clamped, the compression plate 21 contacts the profile, and the spring 20 is compressed, which can play a buffering role to prevent the profile from being pinched and at the same time enhance the clamping force on the profile.

[0017] Working principle:

[0018] First, adjust the adjustable limiting component 8 according to the thickness of the aluminum profile, rotate the capped screw 18 to drive the upper pressure plate 16 to move down along the slide rod 17, and clamp the profile through the elastic cooperation of the spring 20 and the extrusion plate 21 to prevent displacement during bending; place the profile horizontally in the positioning groove formed by the concave panel 14 and the notch 13, ensuring that its two ends are tightly attached to the base plate 12 of the fixed plate 3 and the movable plate 7 respectively. Rotate the screw 5 by the crank handle 6 to drive the movable plate 10 to slide along the T-shaped limiting groove 9, so that the movable plate 7 moves synchronously until the base plate 12 is inserted into the through hole 11 and presses against the end of the profile, completing the precise adjustment of the horizontal gap.

[0019] Subsequently, the pressing assembly 2 is activated, and the hydraulic cylinder drives the pressing block to press down vertically on the middle of the profile. The sliding fit between the concave panel 14 and the notch 13 ensures that the profile remains stably positioned during bending, while the cushioning effect of the extrusion plate 21 prevents damage to the profile surface. After bending is completed, the pressing block is reset, and the rocker handle 6 is turned in the opposite direction to make the moving plate 7 retract, so that the formed workpiece can be taken out. By adjusting the feed amount of the screw 5, it can adapt to the processing needs of profiles of different lengths. The overall operation is simple and the positioning is reliable.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
