Description

Technical Field

[0001] This utility model relates to the field of mechanical bending technology, and in particular to an aluminum profile bending device. Background Technology

[0002] An aluminum profile bending machine is a mechanical device used to bend aluminum profiles into specific shapes. It bends the aluminum profile under precisely controlled conditions by applying pressure and bending force, and is commonly used in the processing of aluminum alloy profiles. This device has a compact structure, is simple to operate, and enables efficient mass production. A bending machine generally consists of bending dies, a hydraulic system, and an electrical control system. It can adjust the pressure and bending angle according to different aluminum profile specifications to meet production needs. It is widely used in industries such as construction, machinery, and automobiles, and plays a particularly important role in the production of door and window frames, brackets, and other components.

[0003] Patent CN221133680U discloses an aluminum profile bending device. Specifically, the patent discloses a technical solution comprising: a frame, a conveying assembly mounted on the frame for pulling aluminum tubes, two fixed pressure rollers positioned behind the upper end face of the frame, and an adjusting roller assembly positioned in front of the upper end face of the frame, located between the two fixed pressure rollers; the adjusting roller assembly includes a fixed assembly, a rotating assembly, a moving assembly, and an unlocking assembly. This achieves the technical effect that: the adjusting roller assembly has a posture locking function, effectively maintaining its position and posture when frequent movement is not required; and it can also unlock the posture lock of the adjusting roller assembly, allowing for adjustment at any time when frequent movement of the pressing rollers is required.

[0004] Existing equipment is prone to wear and tear during long-term use, leading to a gradual decline in its accuracy and efficiency, which in turn affects production quality. At the same time, if the aluminum profiles are not properly pre-treated during the bending process, the surface is prone to oxidation, forming an oxide film, which reduces the corrosion resistance of the aluminum profiles. This not only affects the service life of the aluminum profiles themselves, but may also lead to unsatisfactory bending results, further affecting the overall quality and reliability of the product.

[0005] Therefore, we propose an aluminum profile bending device. Utility Model Content

[0024] The working process of this utility model: Step 1: When the device is started, the water pump sprays the pretreatment liquid from the pretreatment tank 3 through the connecting pipe 4 to the spray head 5. The water flow from the spray head 5 evenly covers the surface of the aluminum profile, so that the pretreatment liquid can form a protective film on the surface of the aluminum profile to prevent oxidation reaction and thus improve the corrosion resistance of the aluminum profile. During this process, the spray head 5 is located above the pretreatment plate 2 to ensure that the aluminum profile is uniformly pretreated before bending. Step 2: The moving component controls the movement of the bidirectional threaded rod 16 through the knob 18, thereby driving the threaded block 17 to move horizontally.

Through the cooperation of the first roller 20, the second roller 21 and the guide block 23, the aluminum profile is accurately clamped and positioned. The moving component can adapt to different types of aluminum profiles. Through precise control, the stability and accuracy of the aluminum profile during the bending process are ensured. Step 3: After the aluminum profile is precisely positioned, the motor 8 drives the rotating shaft 11 to rotate, which in turn drives the first bending head 12 and the second bending head 14 to move in coordination. Through the cooperation of the protrusions and convex rods between the two, the aluminum profile is bent into the required shape under the action of the protrusions and convex rods. The bending roller 25 and the bending seat 24 are precisely fixed to the aluminum profile through the fixing holes to ensure that the aluminum profile will not be deviated or damaged during the bending process, thereby obtaining a high-quality bending effect.
