Description

Technical Field

[0001] This utility model relates to the field of curtain wall construction technology, and in particular to a bending device for aluminum single-panel curtain walls. Background Technology

[0002] Aluminum single-panel curtain walls are a type of metal decorative panel used on building facades. They are typically formed by bending to achieve the desired shape and structure. Bending generally relies on a bending machine in conjunction with a positioning structure to press and bend the aluminum single-panel to meet the design requirements of the building curtain wall in terms of size, angle, and connection method.

[0003] Existing aluminum panel bending equipment typically includes a support frame, a bending mechanism, and a drive unit. The aluminum panel is placed on the worktable and bent by pressing down with a die or pressure bar. To ensure the accuracy of the bending angle and position, the equipment is often equipped with simple stops or backing plates for positioning. However, these structures are mostly fixed stops with limited adjustment methods, making it difficult to adapt to the bending requirements of aluminum panels of different specifications.

[0004] Because existing limiting mechanisms are relatively simple, common problems include: the limiting position cannot be quickly adjusted, the limiting accuracy is low, and the unstable limiting causes displacement of the aluminum panel during bending, resulting in inaccurate bending line positions. Although some devices have adjustable limiting structures, the adjustment structure is complex, inconvenient to use, and cannot accommodate multi-specification processing scenarios. Therefore, a bending device with reliable limiting, quick adjustment, and applicability to aluminum panels of different sizes is needed. Utility Model Content

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a curtain wall aluminum single panel bending device, including a support structure 100, a bending component 200 is provided on the support structure 100, and a limit mechanism 300 is provided on one side of the bending component 200.

[0022] The support structure 100 includes a base 101, on which a first support plate 102 and a second support plate 103 are fixedly connected. The two support plates form a stable left and right support interface, facilitating the installation of the transmission roller and bending assembly 200.

[0023] The bending assembly 200 includes a motor 201, the output shaft of which is fixedly connected to the input end of a reduction gearbox 202. The reduction gearbox 202 is fixedly connected to the base 101, and a pulley 203 is fixedly connected to the output end of the reduction gearbox 202. The reduction gearbox 202 converts the high-speed output of the motor 201 into a low-speed, high-torque transmission more suitable for the operation of the conveying rollers. A first conveying roller 211 and a second conveying roller 212 are disposed between the first support plate 102 and the second support plate 103. A second rotating shaft 210 and a third rotating shaft 209 are sequentially fixed and threaded onto the first conveying roller 211 and the second conveying roller 212. The two ends of the second rotating shaft 210 and the third rotating shaft 209 are rotatably connected to the first support plate 102 and the second support plate 103. The two parallel conveying rollers provide a stable linear conveying trajectory, reducing the vibration of the aluminum sheet before it enters the bending area. A rotating shaft 206 is rotatably connected to the support plate 102. A gear 205 and a pulley 204 are fixedly connected to the rotating shaft 206. The pulley 204 is connected to the pulley 203 via a belt drive. Gears 207 and 208 are fixedly connected to the rotating shaft 210 and rotating shaft 209, respectively. Gear 205 is located between gears 207 and 208, and meshes with them. This gear meshing enables synchronous rotation of the two conveying rollers, preventing inconsistent conveying speeds on the left and right sides. The upper parts of the support plate 102 and support plate 103 have guide holes. A lifting plate 214 is slidably connected within the guide holes. A screw 213 is rotatably connected to the lifting plate 214, and the two screws 213 are threadedly connected to the upper ends of the support plate 102 and support plate 103, respectively. A rotating shaft 216 is rotatably connected to the two lifting plates 214, and a bending roller 215 is fixedly connected to the rotating shaft 216. The lifting plates 214 are adjusted by screw 213 to move the bending roller 215 up and down to adapt to different thicknesses or different bending depths.

[0024] The limiting mechanism 300 includes a support frame 301, with its two ends fixedly connected to the sides of the first support plate 102 and the second support plate 103, respectively. A sliding rod 302 is fixedly connected to the support frame 301, and two sliders 303 are symmetrically arranged on the sliding rod 302. A limiting plate 304 is fixedly connected to the top surface of each slider 303, and the limiting plate 304 is used to abut against the side of the aluminum single panel to maintain lateral position consistency. An ear plate 305 is fixedly connected to the side of each slider 303, and a connecting rod 306 is hinged to the ear plate 305. A second screw 308 is threadedly connected to the support frame 301, with a bearing 309 interference-fitted to one end of the second screw 308 and a rocker arm 310 fixedly connected to the other end. The bearing 309 is fixedly connected to a hinge block 307, and the two connecting rods 306 are hinged to the hinge block 307. The screw 308 pushes the hinge block 307 to generate linear displacement. The geometric linkage of the connecting rod 306 converts the linear displacement into symmetrical movement of the two sliders 303, thereby achieving precise adjustment of the distance between the limiting plates 304. This allows the limiting mechanism 300 to adapt to aluminum panels of different widths, while maintaining the synchronicity of the limiting adjustment process. This ensures that the limiting plates 304 on both sides are simultaneously tightened or loosened, preventing the aluminum panels from becoming biased.

[0025] Working principle: such as Figures 1 to 4 As shown, during the bending process of the aluminum panel for the curtain wall, the aluminum panel is first placed above conveyor roller 211 and conveyor roller 212. Motor 201 drives gearbox 202 to output power. Pulley 203 at the output end of gearbox 202 drives pulley 204 via a belt, causing shaft 206 to rotate. Gear 205 on shaft 206 meshes with gears 207 and 208, causing shafts 210 and 209 to rotate synchronously. This drives conveyor rollers 211 and 212 to convey the aluminum panel in the same direction, ensuring its stable entry into the bending area. After the aluminum panel enters below the bending roller 215, the lifting plate 214 can be moved up and down along the guide holes on the support plate 102 and the support plate 203 by adjusting the screw 1 213, thereby driving the rotating shaft 4 216 and the bending roller 215 to adjust up and down, so that the bending roller 215 applies bending force to the aluminum panel to realize the bending process.

[0026] A limiting mechanism 300 is installed on the side of the bending assembly 200. Its function is to laterally position the aluminum panel before it enters the bending roller 215, ensuring that the aluminum panel maintains a stable position during conveying and bending. A slide rod 302 is provided on the support frame 301, and two sliders 303 are respectively sleeved on the slide rod 302, which can move linearly along the slide rod 302. The top of each slider 303 is fixed with a limiting plate 304. The two limiting plates 304 can be moved inward or outward during adjustment to abut against the two side edges of the aluminum panel, thereby adapting to the width of the aluminum panel and providing lateral limiting. An ear plate 305 is fixed to the side of the slider 303. The ear plate 305 is hinged to the connecting rod 306, and the other end of the connecting rod 306 is hinged to the hinge block 307. When the screw 2 308 rotates, the bearing 309 at the end of the screw 2 308 drives the hinge block 307 to move along the length of the support frame 301. The movement of the hinge block 307 causes the two connecting rods 306 to swing symmetrically, causing the two sliders 303 to move simultaneously in opposite or opposite directions along the sliding rod 302: when the connecting rod 306 swings inward, the two sliders 303 move closer to each other, realizing the clamping and positioning of the aluminum panel by the limiting plate 304; when the connecting rod 306 swings outward, the two sliders 303 move away from each other, and the distance between the limiting plates 304 increases, which is suitable for aluminum panels with a larger width.

[0027] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
