Description

Technical Field

[0001] This utility model relates to the field of aluminum profile bending technology, specifically to an aluminum profile bending device with automatic feeding function. Background Technology

[0002] Aluminum profiles are widely used in building curtain walls, transportation, and electronic equipment due to their advantages such as being lightweight, corrosion-resistant, and recyclable. Bending aluminum profiles is a key process for shaping their complex structures; for example, curved window frames for buildings and lightweight automotive parts both require bending to form.

[0003] For example, Chinese utility model patent application number 202122901273.1 discloses an aluminum profile bending device. This device allows for adjustment based on the length of the aluminum profile body via an adjustment mechanism, enabling the aluminum profile body to be placed on a support plate for bending operations. This improves bending efficiency, saves time and labor, and is highly practical. It also ensures that the clamping plate is tightly attached to the surface of the aluminum profile body, preventing the aluminum profile body from shifting, thereby improving the bending effect. However, this device still has certain shortcomings.

[0004] Relying on manual material loading, operators need to manually move aluminum profiles to the bending station, which is labor-intensive and inefficient. Prolonged handling can easily cause operator fatigue, leading to decreased attention and an increased probability of operational errors. This results in quality problems such as scratches and deformation on the aluminum profile surface, producing a large number of defective products and increasing production costs. Utility Model Content

[0005] The purpose of this utility model is to provide a bending device for aluminum profiles with automatic feeding, so as to solve the problems mentioned in the background art. Currently, the market relies on manual feeding, and operators need to manually carry aluminum profiles to the bending station. This is labor-intensive, inefficient, and the long-term carrying can easily cause operator fatigue, leading to decreased attention and an increased probability of operational errors. As a result, quality problems such as scratches and deformation on the surface of the aluminum profiles are caused, resulting in a large number of defective products and increased production costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending device for aluminum profiles with automatic feeding effect, including a workbench, a support frame installed above the workbench, and a connecting plate installed below the support frame via a hydraulic rod, an upper bending die installed below the connecting plate, a lower bending die installed on the upper surface of the workbench, and guide rail assemblies provided on both the left and right sides of the lower bending die;

[0007] A storage box is installed above the workbench via a fixed frame. A vertical plate is installed on the rear side of the workbench, and a cylinder is installed on the rear side of the vertical plate. A movable block is installed on the front side of the cylinder via a pneumatic telescopic rod. Connecting seats are installed on both the front and rear sides of the movable block. A rotating roller is installed between the connecting seats, and a push bar assembly and a support bar assembly are installed on the rotating roller.

[0008] Preferably, the lower bending die is located directly below the upper bending die, and the upper surface of the lower bending die is provided with a bending groove.

[0009] With the above structural design, the lower bending die and the upper bending die are precisely aligned vertically, the bending groove ensures the accurate bending position of the aluminum profile body, and the vertical pressing of the hydraulic rod improves the bending accuracy and stability.

[0010] Preferably, a movable plate is installed at the bottom of the bending groove via a telescopic spring, and the movable plate is slidably connected to the bending groove.

[0011] With the above structural design, the movable plate in the bending groove automatically resets after bending through the telescopic spring, buffering the pressure while pushing out the finished product, making it easy to pick up the material.

[0012] Preferably, the guide rail assembly is provided with a limit block, and the aluminum profile body is slidably connected to the guide rail assembly.

[0013] With the above structural design, the limiting block of the guide rail assembly constrains the conveying position of the aluminum profile body, ensuring that the aluminum profile body slides stably to the bending station and reducing bending failures caused by position deviation.

[0014] Preferably, the storage box has an open structure at both the top and bottom, the aluminum profile body is slidably connected to the storage box, and the storage box is located above the guide rail assembly.

[0015] With the above structural design, the upper and lower openings of the storage box facilitate the stacking of aluminum profiles. The bottom aluminum profile body automatically abuts against the guide rail assembly, realizing continuous feeding and improving production continuity.

[0016] Preferably, a connecting shaft is provided between the connecting seats, the rotating roller is sleeved on the connecting shaft, the rotating roller is rotatably connected to the connecting shaft, and the rotational friction between the rotating roller and the connecting shaft is less than the weight of the aluminum profile.

[0017] With the above structural design, the cylinder is activated, and the cylinder drives the movable block to move to the left through the pneumatic telescopic rod. When the rotating roller on the movable block passes under the storage box, the support assembly abuts against the horizontal plate under the action of gravity. The pusher assembly pushes an aluminum profile body along the guide slide rail assembly to the bending lower die position for feeding.

[0018] Preferably, the push bar assembly has a hollow structure design, the support bar assembly has a solid structure design, the weight of the support bar assembly is greater than that of the push bar assembly, a horizontal plate is installed on the right side of the movable block, when the push bar assembly and the support bar assembly are not under force, the support bar assembly abuts against the horizontal plate, and the left end of the push bar assembly is in a horizontal state.

[0019] With the above structural design, the weight of the support bar assembly is greater than that of the push bar assembly. When not under force, the support bar assembly abuts against the horizontal plate, keeping the push bar assembly horizontal and accurately controlling the push of one aluminum profile at a time, thus avoiding the stacking of multiple materials.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the aluminum profile bending device with automatic feeding function:

[0021] 1. Automatic feeding and precise conveying: The aluminum profile body in the storage box can be pushed along the guide rail assembly for feeding. The moving block pushes the aluminum profile body to the bending die through the push bar assembly on the rotating roller. No manual handling is required. At the same time, the guide rail assembly ensures the precise conveying path and reduces offset error.

[0022] 2. Continuous operation and high-efficiency production: The cylinder drives the pneumatic telescopic rod to move the movable block back and forth. The support bar assembly and the push bar assembly work together to realize the synchronous action of "picking up and feeding". One cycle can complete one feeding. With the rapid pressing down of the hydraulic rod, the production efficiency is greatly improved and the waiting time is reduced. Attached Figure Description

[0031] Please see Figures 1-6 This utility model provides a technical solution: a bending device for aluminum profiles with automatic feeding effect, including a workbench 1, a support frame 2, a hydraulic rod 3, a connecting plate 4, an upper bending die 5, a lower bending die 6, a bending groove 7, a telescopic spring 8, a movable plate 9, a guide rail assembly 10, a fixed frame 11, a storage box 12, a vertical plate 13, a cylinder 14, a pneumatic telescopic rod 15, a movable block 16, a connecting seat 17, a rotating roller 18, a push bar assembly 19, a support bar assembly 20, and a horizontal plate 21. The support frame 2 is installed above the workbench 1, and the connecting plate 4 is installed below the support frame 2 via the hydraulic rod 3. The upper bending die 5 is installed below the connecting plate 4. The lower bending die 6 is installed on the upper surface of the workbench 1, located directly below the upper bending die 5, and the upper surface of the lower bending die 6 has an opening. The upper bending die 5 is driven down by a hydraulic rod 3 via a bending groove 7. The bending of the aluminum profile body is completed by the cooperation of the bending groove 7 and the movable plate 9. The movable plate 9 is installed at the bottom of the bending groove 7 via a telescopic spring 8. The movable plate 9 is slidably connected to the bending groove 7. After the aluminum profile body is bent, the movable plate 9 moves upward and resets under the action of the telescopic spring 8, pushing out the finished product. Guide slide rail assemblies 10 are provided on both the left and right sides of the lower bending die 6. Limit blocks are provided on the guide slide rail assemblies 10. The aluminum profile body is slidably connected to the guide slide rail assemblies 10. When the aluminum profile body is conveyed, it can move along the guide slide rail assemblies 10, so that the aluminum profile body can be pushed above the lower bending die 6 and abut against the limit blocks on the guide slide rail assemblies 10, which facilitates bending.

[0032] A storage box 12 is mounted on top of the workbench 1 via a fixed frame 11. The storage box 12 has an open structure at both the top and bottom. The aluminum profile body is slidably connected to the storage box 12. The storage box 12 is located above the guide rail assembly 10. The aluminum profile bodies are stacked inside the storage box 12, with the bottom aluminum profile body abutting against the guide rail assembly 10. A vertical plate 13 is mounted on the rear side of the workbench 1, and a cylinder 14 is mounted on the rear side of the vertical plate 13. A movable block 16 is mounted on the front side of the cylinder 14 via a pneumatic telescopic rod 15. Connecting seats 17 are mounted on both the front and rear sides of the movable block 16, and a connecting shaft is provided between the connecting seats 17. A rotating roller 18 is sleeved on the connecting shaft, and the rotating roller 18 is rotatably connected to the connecting shaft. The rotational friction between the rotating roller 18 and the connecting shaft is less than the weight of the aluminum profile. The cylinder 14 drives the pneumatic telescopic rod 15 to move the movable block 16 to the left. When the rotating roller 18 on block 16 passes under the storage box 12, the support assembly 20 droops to the horizontal plate 21 due to gravity. The pushing strip assembly 19 pushes an aluminum profile body along the guide rail assembly 10 to the bending lower die 6 position, realizing feeding. The rotating roller 18 is installed between the connecting seats 17, and the pushing strip assembly 19 and the support assembly 20 are installed on the rotating roller 18. The pushing strip assembly 19 has a hollow structure design, and the support assembly 20 has a solid structure design. The weight of the support assembly 20 is greater than that of the pushing strip assembly 19. The horizontal plate 21 is installed on the right side of the movable block 16. When the pushing strip assembly 19 and the support assembly 20 are not under force, the support assembly 20 abuts against the horizontal plate 21. The left end of the pushing strip assembly 19 is in a horizontal state. After feeding is completed, the cylinder 14 drives the pneumatic telescopic rod 15 to move the movable block 16 to the right to reset. When the movable block 16 passes under the storage box 12, as shown in the instruction manual... Figure 4 Included with instruction manual Figure 5 As shown, since the rotational friction between the rotating roller 18 and the connecting shaft is less than the weight of the aluminum profile, the push bar assembly 19 rotates with the rotating roller 18 under the obstruction of the aluminum profile body below the storage box 12, so that the push bar assembly 19 can pass smoothly under the storage box 12. After passing, the support bar assembly 20 rotates under the action of gravity until it abuts against the horizontal plate 21 and is reset.

[0033] Working principle: When using this aluminum profile bending device with automatic feeding function, firstly, the cylinder 14 drives the pneumatic telescopic rod 15 to move the movable block 16 to the left. When the rotating roller 18 on the movable block 16 passes under the storage box 12, the support bar assembly 20 hangs down to the horizontal plate 21 due to gravity. The pushing bar assembly 19 pushes an aluminum profile body along the guide slide rail assembly 10 to the position of the lower bending die 6 to realize feeding. The aluminum profile body abuts against the limit block on the guide slide rail assembly 10. The hydraulic rod 3 drives the upper bending die 5 to press down. The bending of the aluminum profile body is completed by the cooperation of the bending groove 7 and the movable plate 9. After the aluminum profile body is bent, the movable plate 9 moves upward and resets under the action of the telescopic spring 8, and the finished product is pushed out. The finished product can be picked up manually.

[0034] After feeding is completed, cylinder 14 drives pneumatic telescopic rod 15 to move movable block 16 to the right and reset. When movable block 16 passes under storage box 12, due to the rotational friction between rotating roller 18 and connecting shaft being less than the weight of aluminum profile, push bar assembly 19 rotates with rotating roller 18 under the obstruction of aluminum profile body below storage box 12, allowing push bar assembly 19 to pass smoothly under storage box 12. After passing, support bar assembly 20 rotates under gravity to abut against horizontal plate 21 and resets, allowing for the next material conveying, thus completing a series of operations. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
