[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Example

[0023] Please refer to Figures 1-4 The small-arc bending device for aluminum processing provided by this utility model mainly consists of a base 1, a bending operation component, and a positioning component. The bending operation component includes a pressure application part and an arc-shaped bending mold structure 2 arranged along the length direction of the base 1. The pressure application part can move vertically above the arc-shaped bending mold structure 2, thereby applying bending force to the aluminum material. The positioning component includes two sets of positioning parts symmetrically arranged on the base 1. These two sets of positioning parts can move towards or away from each other along the width direction of the base 1 to accommodate aluminum materials of different widths. Each positioning part is equipped with a V-shaped limiting frame 44 with a concave limiting space. A limiting plate 43 that can move vertically towards the concave limiting center is also provided inside the V-shaped limiting frame 44, thereby meeting the positioning requirements of aluminum materials of different thicknesses.

[0024] Specifically, the length of base 1 is Figure 1 The X-direction shown has a width direction of [missing information]. Figure 1 The Y direction is shown.

[0025] Specifically, the device also includes a mounting bracket 6 installed on top of the base 1, and the pressure application part consists of a hydraulic cylinder 7 and a bending module 71. The hydraulic cylinder 7 is securely mounted on the mounting bracket 6 to ensure its stability during operation. The bending module 71 is coaxially arranged above the arc-shaped bending die structure 2, and the output rod of the hydraulic cylinder 7 is tightly connected to the bending module 71.

[0026] When the hydraulic cylinder 7 is activated, the output rod drives the bending module 71 to move vertically. By precisely controlling the stroke and pressure of the output rod, the bending force and depth of the aluminum material can be precisely controlled, thereby improving the accuracy and quality of the bending process.

[0027] The top of the V-shaped limiting frame 44 is fixedly connected to a first nut block 41 by welding or bolting, and the first nut block 41 is threadedly connected to a first threaded rod 42. The bottom end of the first threaded rod 42 is fixed to the limiting plate 43 by welding or threaded fastening, and its top end is fixedly connected to a first rotary handle for easy operation. By rotating the first rotary handle, the operator can easily adjust the vertical position of the limiting plate 43 within the V-shaped limiting frame 44 using the threaded transmission principle, thereby flexibly adapting to the positioning requirements of aluminum materials of different thicknesses and ensuring that the aluminum material is not inaccurately positioned due to thickness differences during processing.

[0028] To facilitate the movement of the two positioning units towards or away from each other, the device is equipped with an adjustment assembly 5. The adjustment assembly 5 mainly includes a mounting shell 51, on the inner side of which a second threaded rod 53 is rotatably connected via a bearing. Two sets of second nut blocks 54 are symmetrically threaded onto the second threaded rod 53. The threads of the second nut blocks 54 and the second threaded rod 53 are tightly engaged to ensure accurate transmission.

[0029] A connecting rod 52 is fixed to the second nut block 54 by welding or bolting. One end of the connecting rod 52 extends movably through the outside of the mounting shell 51 and is fixedly connected to the moving plate 3 by welding or bolting. The V-shaped limiting frame 44 is fixedly connected to the moving plate 3. When the second threaded rod 53 is rotated, due to the threaded connection between the two sets of second nut blocks 54 and the second threaded rod 53, and the opposite thread directions, the two sets of second nut blocks 54 will drive the connecting rod 52 and the moving plate 3 to move towards or away from each other, thereby adjusting the position of the V-shaped limiting frame 44 to adapt to the clamping and positioning requirements of aluminum materials of different widths.

[0030] The two sets of oppositely oriented threads on the second threaded rod 53 precisely match the inner wall of the second nut block 54, ensuring that the two sets of second nut blocks 54 can move synchronously and stably in opposite directions when the second threaded rod 53 is rotated. One end of the second threaded rod 53 extends to the outside of the mounting housing 51 and is fixedly connected to a second handle for easy manual rotation by the operator. Inside the mounting housing 51, a guide rod 55 parallel to the second threaded rod 53 is also fixedly connected, and one end of the second nut block 54 slides onto the surface of the guide rod 55. The guide rod 55 guides the movement of the second nut block 54, preventing it from shifting or wobbling during movement, ensuring the smoothness and accuracy of the entire adjustment process.

[0031] Furthermore, to improve production efficiency, multiple V-shaped limiting frames 44 are provided, and these V-shaped limiting frames 44 are evenly arranged along the axial direction of the moving plate 3. Multiple V-shaped limiting frames 44 can simultaneously fix and clamp multiple aluminum workpieces, completing the bending processing of multiple workpieces at one time, greatly shortening the processing time and improving production efficiency.

[0032] The top of the base 1 is machined with an arc-shaped groove 100, into which the arc-shaped bending die structure 2 can be inserted. The end of the arc-shaped bending die structure 2 is integrally formed or welded with a fixing block 8. The fixing block 8 has threaded holes, and is connected and fixed to the base 1 by fixing bolts. This installation method is convenient and quick. When processing aluminum materials with different curvatures, the fixing bolts can be easily loosened, and different sizes of arc-shaped bending die structures 2 can be replaced, enhancing the versatility and adaptability of the device.

[0033] To prevent damage to the aluminum surface during bending, an arc-shaped protective pad 21 is attached to the top of the arc-shaped bending mold structure 2 by means of glue or bolts, and a flat protective pad 45 is attached to the inner side of the V-shaped limit frame 44 by means of glue or bolts.

[0034] The curved protective pad 21 and the flat protective pad 45 are usually made of materials with certain elasticity and wear resistance, such as rubber and silicone. They can effectively buffer pressure during processing, prevent defects such as scratches and indentations on the aluminum surface, and improve the surface quality of the product.

[0035] In some of the operating procedures of this application, firstly, the fixing block 8 of the arc bending mold structure 2 is aligned with the threaded hole at the end of the arc groove 100 at the top of the base 1 and inserted into the arc groove 100. Then, the fixing block 8 is fastened to the base 1 with fixing bolts to ensure that the arc bending mold structure 2 is installed firmly.

[0036] Depending on the thickness of the aluminum material to be processed, manually turn the first handle to make the first threaded rod 42 rotate in the first nut block 41, which will drive the limiting plate 43 to move vertically within the V-shaped limiting frame 44 and adjust it to a suitable height position.

[0037] According to the width of the aluminum material to be processed, turn the second handle, and the second threaded rod 53 will rotate accordingly. Under the action of the thread, the two sets of second nut blocks 54 will move towards or away from each other along the guide rod 55. The moving plate 3 and the V-shaped limit frame 44 will be adjusted in position through the connecting rod 52 so that the spacing between the V-shaped limit frames 44 is adapted to the width of the aluminum material.

[0038] The aluminum material to be processed is placed between two sets of V-shaped limiting frames 44, with both sides of the aluminum material contacting the inner sidewalls of the V-shaped limiting frames 44. The V-shaped limiting frames 44 and the limiting plates 43 are used to position and clamp the aluminum material. If multiple workpieces are processed simultaneously, multiple aluminum materials can be placed sequentially within multiple V-shaped limiting frames 44.

[0039] Hydraulic cylinder 7 is activated, and its output rod extends, causing bending module 71 to move vertically above the arc-shaped bending die structure 2, applying pressure to the aluminum material. As bending module 71 descends, the aluminum material is gradually bent into the required small arc on the arc-shaped bending die structure 2. During processing, arc-shaped protective pad 21 and flat protective pad 45 effectively protect the surface of the aluminum material, preventing scratches and other problems.

[0040] When processing aluminum materials with different curvatures, first shut down the hydraulic cylinder 7 to return the bending module 71 to its initial position. Then loosen the fixing bolts, remove the curved bending die structure 2 from the base 1, replace it with a suitable curved bending die structure 2, and repeat the above steps for installation, adjustment, and processing.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
