Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy door and window production technology, specifically a bending device for aluminum alloy door and window production. Background Technology
[0002] Aluminum alloy doors and windows refer to doors and windows made using extruded aluminum alloy profiles as frames, mullions, and sashes. In the production process of irregularly shaped aluminum alloy door and window components, bending devices are needed to bend the aluminum alloy raw materials. Workers mainly use stamping and bending dies to process the irregularly shaped raw materials. However, when processing irregularly shaped raw materials, workers usually place the aluminum alloy raw material on top of the die, and then press down with the bending die head to bend the aluminum alloy raw material to fit the die, thus completing the bending process. In the production process, it is often necessary to process irregularly shaped raw materials with different angles. However, since the angle of the die is fixed, the workers need to change dies with different angles. The dies are mostly fixed by bolts, which is time-consuming and laborious to replace. At the same time, the contact area between the die and the aluminum alloy raw material is rubbed when the aluminum alloy raw material is bent, which generates heat. After a long period of processing, the die temperature will continue to rise if it is not cooled. When the workers handle the workpiece, they are likely to be burned by the die. Moreover, the high temperature will accelerate the wear of the die and reduce its service life. Utility Model Content

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1
[0026] like Figures 1-6 As shown, a bending device for aluminum alloy door and window production includes: an equipment cabinet 1, a mounting frame 11 fixedly connected to the top of the equipment cabinet 1, a hydraulic cylinder 12 fixedly mounted on the top of the mounting frame 11, a bending plate 13 fixedly mounted on the bottom of the hydraulic cylinder 12, and two rotatably connected carrier plates 14 on the top of the equipment cabinet 1; an adjustment component, located on the equipment cabinet 1, for adjusting the included angle of the two carrier plates 14; and a cooling component, located inside the equipment cabinet 1, for cooling the two carrier plates 14.
[0027] During processing, the aluminum alloy frame is placed on two carrier plates 14, and the part to be bent is aligned with the bending plate 13. Then, the angle between the two carrier plates 14 is adjusted by the adjustment component according to the required bending angle. After the adjustment is completed, the hydraulic cylinder 12 is activated to push the bending plate 13 downward. The bending plate 13 squeezes the aluminum alloy frame to make it bend. After the aluminum alloy frame bends and fits the two carrier plates 14, the processing is completed. The hydraulic cylinder 12 drives the bending plate 13 to retract to the initial position. During bending, the cooling component can cool the two carrier plates 14 to prevent the aluminum alloy frame from rubbing against the two carrier plates 14 when deforming, which would cause its temperature to rise. Example 2
[0028] Based on Embodiment 1, the adjustment assembly includes: a groove 2, a bidirectional threaded screw 21, a movable block 22, a connecting block 23, and a support plate 24. A groove 2 is provided on the top of the equipment cabinet 1. A bidirectional threaded screw 21 is rotatably connected between the inner walls of the groove 2 and its opposite sides. Movable blocks 22 are threaded onto two oppositely oriented threads on the outer two sections of the bidirectional threaded screw 21. Connecting blocks 23 are fixedly connected to the tops of the two movable blocks 22 and the bottoms of the two carrier plates 14, respectively. A support plate 24 is connected between the two connecting blocks 23 located on the same side. A movable cavity 25 is provided on the equipment cabinet 1, and one end of the bidirectional threaded screw 21 extends into the movable cavity 25. A bevel gear a26 is fixedly connected to the equipment cabinet 1. A drive motor 27 is fixedly installed at the top of the equipment cabinet 1. The drive shaft at the top of the drive motor 27 extends into the movable cavity 25 and is fixedly connected to a bevel gear b28. The bevel gear b28 meshes with the bevel gear a26. Two guide rods 29 are fixedly connected between the inner walls of opposite sides of the groove 2. The two guide rods 29 are located on both sides of the bidirectional threaded screw 21. Two moving blocks 22 are slidably connected to the outside of the two guide rods 29. A fixed frame 210 is fixedly connected at the bottom of the groove 2 near the middle position. Two carrier plates 14 are rotatably connected between the inner walls of opposite sides of the fixed frame 210.
[0029] When adjusting the angle between the two carrier plates 14, the drive motor 27 is started to drive the bevel gear b28 to rotate. The rotation of the bevel gear b28 meshes with the bevel gear a26, which in turn drives the bevel gear a26 to drive the bidirectional threaded screw 21 to rotate. When the bidirectional threaded screw 21 rotates, it meshes with the two moving blocks 22. The moving blocks 22 are restricted by the two guide rods 29, so that the moving blocks 22 can only move in the horizontal direction. Therefore, when the threads are engaged, the two moving blocks 22 will move relative to each other. When the moving blocks 22 move, they drive the connected carrier plates 14 to close and reduce the angle through the support plate 24. The drive motor 27 is a forward and reverse motor. When the drive motor 27 reverses, the two carrier plates 14 separate and expand the angle according to the above principle. In this way, it can be adjusted according to the required bending degree without replacing the carrier plates 14 with different angles, which is more time-saving and labor-saving, and improves the practicality of the device. Example 3
[0030] Based on Embodiment 1, the cooling component includes: a water tank 3, a water pump 31, a water supply pipe 32, a cooling chamber 33, a radiator 34, and a return pipe 35. The equipment cabinet 1 is equipped with a water tank 3, and the water tank 3 is equipped with a water pump 31. The top of the water pump 31 is fixedly connected to the water supply pipe 32. The two carrier plates 14 are each equipped with a cooling chamber 33. One end of the water supply pipe 32 passes through the equipment cabinet 1 and is connected to the two cooling chambers 33. The top of the water tank 3 is fixedly installed with a radiator 34. The radiator 34 is equipped with a return pipe 35. One end of the return pipe 35 is connected to the two cooling chambers 33 respectively, and the other end of the return pipe 35 is connected to the water tank 3.
[0031] When bending, the water pump 31 is activated to draw out the coolant from the water tank 3 and deliver it to the two cooling chambers 33 through the water supply pipe 32. The coolant absorbs the heat from the carrier plate 14, thereby initiating the cooling effect. The coolant that has absorbed the heat flows to the radiator 34 through the return water pipe 35, where it is cooled down to ensure that the coolant is at a low temperature. After being cooled, the coolant flows back into the water tank 3 to form a circulation. This can prevent the carrier plate 14 from heating up due to friction with the workpiece during long-term processing, thus avoiding burns to the user's hands.
