Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum bracket technology, specifically to an aluminum bracket bending device. Background Technology
[0002] Aluminum brackets are structural components made primarily of aluminum alloy. They are lightweight yet strong, capable of withstanding significant loads. They exhibit excellent corrosion resistance, and their surfaces, after oxidation treatment, are resistant to rust, making them suitable for complex environments such as humid and acidic / alkaline conditions. They also possess good machinability, allowing them to be manufactured into various complex shapes through processes such as die casting and extrusion. They are widely used in electronic equipment, medical devices, and automotive manufacturing.
[0003] The core of the aluminum bracket bending device is to achieve precise bending and shaping through mechanical structure. The equipment uses hydraulic power and is equipped with a U-shaped custom mold, which can apply directional torque and pressure to the aluminum bracket, making it bend into a U-shape along a preset trajectory. However, the current aluminum bracket bending devices often have problems with different degrees of bending and inconsistent shapes.
[0004] In view of this, we propose an aluminum bracket bending device. Utility Model Content

A connecting plate is fixedly installed at one end of the piston end of the hydraulic cylinder, and the other end of the connecting plate is fixedly connected to the slide rail.
[0011] In a further embodiment, the fixed column, slide rail, and rack are provided in two sets.
[0012] In a further embodiment, the movement trajectories of the first and second tabletops do not intersect.
[0013] In a further embodiment, the fixed column and the second platform are at the same horizontal level, thereby making the torsion more stable.
[0014] In a further embodiment, an auxiliary component is provided on the workbench. The auxiliary component includes a sleeve. The sleeve is fixedly installed on the top of the workbench. An electric telescopic rod is sleeved inside the sleeve. A fixed rod is fixedly installed on the top of the workbench.

[0015] In a further embodiment, the sleeve, electric telescopic rod, fixing rod, and L-shaped frame are provided in two sets.
[0016] In a further embodiment, the electric telescopic rod and the fixed rod are located at the same horizontal height, thereby making the torsion more stable.
[0017] Compared with the prior art, the present invention provides an aluminum bracket bending device, which has the following advantages:
[0018] 1. This aluminum bracket bending device, in order to improve the bending efficiency and shape consistency of the aluminum bracket, is equipped with a bending assembly. First, the aluminum bracket is placed between the first cylinder, the second cylinder and the rotating shaft. Then, the hydraulic cylinder is activated, and in conjunction with the arc-shaped platform, fixed column, first gear, first sleeve rod, first platform, second gear, second sleeve rod, second platform, slide rail, rack, hydraulic cylinder and connecting plate, the vertical aluminum bracket is bent into a U-shape, and each aluminum bracket has a consistent degree of bending and shape, thus improving bending efficiency and quality.
[0019] 2. In order to facilitate the collection of the bent aluminum brackets, the aluminum bracket bending device raises one end of the L-shaped frame by activating the electric telescopic rod. After the L-shaped frame is tilted, the aluminum brackets placed on the L-shaped frame will roll directly onto the worktable and be blocked by the baffle to prevent them from rolling off. This improves the collection efficiency of the aluminum brackets after the bending work is completed, thus improving work efficiency. Attached Figure Description

[0032] Please see Figures 1-6 This utility model provides a technical solution:
[0033] An aluminum bracket bending device includes a workbench 1, with a leg 2 fixedly installed at the bottom of the workbench 1 and a baffle 3 fixedly installed at the top of the workbench 1.
[0034] In one embodiment of this utility model, a bending assembly 4 is provided on the workbench 1. The bending assembly 4 includes an arc-shaped platform 41, a fixed column 42 fixedly installed on the top of the arc-shaped platform 41, a rotating shaft 43 rotatably installed inside the workbench 1 via bearing components, a first sleeve rod 441 fixedly installed outside the rotating shaft 43, a first gear 441 fixedly installed at the bottom of the first sleeve rod 441, a first table surface 442 fixedly installed at the top of the first sleeve rod 441, a first cylinder 443 fixedly installed on the first table surface 442, a second sleeve rod 451 fixedly installed outside the rotating shaft 43, a second gear 45 fixedly installed at the bottom of the second sleeve rod 451, and a fixed column 42 fixedly installed at the top of the second sleeve rod 451. A second platform 452 is fixedly installed, and a second cylinder 453 is fixedly installed on the top of the second platform 452. A slide rail 46 is fixedly installed inside the worktable 1, and a rack 47 is slidably installed inside the slide rail 46. A first gear 44 and a second gear 45 mesh with the rack 47. A hydraulic cylinder 48 is fixedly installed inside the worktable 1. A connecting plate 49 is fixedly installed at one end of the piston end of the hydraulic cylinder 48, and the other end of the connecting plate 49 is fixedly connected to the slide rail 46. There are two sets of fixed columns 42, slide rails 46 and racks 47. The movement trajectories of the first platform 442 and the second platform 452 do not intersect. The fixed columns 42, the first platform 442 and the second platform 452 are at the same horizontal height.
[0035] In this embodiment, the operator places the center of the straight aluminum bracket to be bent in the central area between the first cylinder 443, the second cylinder 453, and the rotating shaft 43. The operator activates the hydraulic cylinder 48, whose piston pushes the connecting plate 49. The connecting plate 49 drives the slide rail 46 and the rack 47 to move in a preset direction. The linear motion of the rack 47 simultaneously drives the first gear 44 and the second gear 45 meshing with it to rotate. Both drive the first platform 442 and the second platform 452 to perform circular motion around the rotating shaft 43. The first platform 442 and the second platform 452... Moving in opposite directions simultaneously, the first platform 442 and the second platform 452 apply lateral forces to the aluminum bracket through the first cylinder 443 and the second cylinder 453 respectively. After the aluminum bracket is bent, it abuts against the two sets of fixed columns 42. At this time, the aluminum bracket is in a U-shape. Then, the hydraulic cylinder 48 is controlled to move in the opposite direction, driving the rack 47 to reset, so that the first platform 442 and the second platform 452 return to the initial position. The bent aluminum bracket is taken out, and the above process is repeated to achieve continuous processing. This device makes the bending degree and shape of each aluminum bracket consistent, improving bending efficiency and quality.
[0036] In one embodiment of this utility model, an auxiliary component 5 is provided on the workbench 1. The auxiliary component 5 includes a sleeve 51. The sleeve 51 is fixedly installed on the top of the workbench 1. An electric telescopic rod 52 is sleeved inside the sleeve 51. A fixed rod 53 is fixedly installed on the top of the workbench 1. An L-shaped frame 54 is fixedly installed on the top of both the electric telescopic rod 52 and the fixed rod 53. Two sets of sleeve 51, electric telescopic rod 52, fixed rod 53 and L-shaped frame 54 are provided. The electric telescopic rod 52 and the fixed rod 53 are located at the same horizontal height.
[0037] In this embodiment, the two ends of the aluminum bracket to be bent are placed on the L-shaped frame 54. After bending, the electric telescopic rod 52 is extended to raise the L-shaped frame 54 at the top, while the L-shaped frame 54 supported by the fixed rod 53 remains stationary. The two sets of L-shaped frames 54 form an inclined plane. The inclined L-shaped frame 54 causes the aluminum bracket to roll down the inclined plane to the designated area on the workbench 1 due to gravity. The baffle 3 blocks the rolling aluminum bracket, preventing it from rolling directly onto the workbench, thus completing the collection of the bent aluminum bracket and improving the collection efficiency.
