Description

Technical Field

[0001] This invention relates to the field of aluminum profile technology, and in particular to an intelligent aluminum profile straightening machine and an aluminum profile straightening process. Background Technology

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. Common aluminum profiles are generally square strip-shaped metal materials. In the production workshop, aluminum profiles often become unsaleable and limited, resulting in a large number of aluminum profiles needing to be stored after production.

[0003] Current straightening equipment suffers from significant limitations in adaptability when straightening irregularly shaped aluminum profiles. Because the straightening rollers or pressure heads are mostly of general-purpose design, they cannot fully conform to the complex cross-sectional shapes of the profiles. This results in uneven and insufficient compression when applying straightening force, preventing the effective release of residual stress within the profile and limiting the straightening effect. Furthermore, irregularly shaped aluminum profiles often have asymmetrical or thin-walled characteristics. If the force application position or intensity is not properly controlled during straightening, secondary defects such as surface indentations, localized depressions, or contour deformation can easily occur. This not only affects the appearance quality but may also lead to deviations in cross-sectional geometric accuracy, causing secondary deformation problems during the straightening process. The final result is low straightening yield and poor dimensional consistency, making it difficult to meet the process requirements of high-precision aluminum profile products. Summary of the Invention

[0004] Based on the technical problem that existing straightening machines cannot straighten irregularly shaped louver aluminum profiles, which can lead to secondary defects such as surface indentations, local depressions, or contour deformation, affecting not only the appearance quality but also potentially causing cross-sectional geometric accuracy to exceed tolerances and resulting in secondary deformation during the straightening process, this invention proposes an intelligent aluminum profile straightening machine and aluminum profile straightening process.

[0011] Preferably, the clamping device further includes a connecting frame, which is slidably inserted into the outer surface of the push plate. A connecting spring is fixedly installed on the outer surface of the connecting frame, one end of which is fixedly installed on the lower surface of the push plate. An electromagnetic component is fixedly installed on the upper surface of the push plate, and the inner wall of the electromagnet of the electromagnetic component is magnetically connected to the outer surface of the connecting rod of the connecting frame.

[0012] Preferably, a double-ended lead screw is rotatably connected to the outer surface of the connecting frame via a bearing, a connecting slider is threaded onto the outer surface of the double-ended lead screw, the inner wall of the connecting slider is slidably inserted into the outer surface of the guide rail of the connecting frame, a connecting scissor frame is hinged to the outer surface of the connecting slider via a pin, a sliding slider is slidably sleeved on the outer surface of the double-ended lead screw, the outer surface of the sliding slider is hinged to the middle pin of the connecting scissor frame, and one end of the connecting scissor frame is hinged to the outer surface of the connecting block of the double-ended lead screw via a pin.

[0013] Preferably, one end of the double-ended lead screw located on one side is connected by a synchronous belt and a synchronous pulley for transmission. A drive motor is fixedly installed on the outer surface of the connecting frame, and one end of the output shaft of the drive motor drives the rotation of the double-ended lead screw through a bevel gear set.

[0014] Preferably, a movable slide groove is fixedly installed on the outer surface of the pin connecting the scissor frame, a pressing frame is slidably inserted into the inner wall of the movable slide groove, a return spring is fixedly installed on the outer surface of the movable slide groove, one end of the return spring is fixedly installed to the outer surface of the pressing frame, a fixed frame is hinged to the inner wall of the pressing frame through a pin and a torsion spring, the inner wall of the fixed frame is slidably inserted into the outer wall of the positioning template block, and the outer surface of the fixed frame is fixed to the positioning template block by bolts screwed into the threaded groove of the positioning template block.

[0015] Preferably, a ranging sensor is fixedly installed on the outer surface of the frame of the mobile component, and a capture camera is fixedly installed on the inner side wall of the frame.

[0016] The present invention discloses an aluminum profile straightening process using an intelligent aluminum profile straightening machine, comprising the following steps:

[0017] S1: After the worker places the aluminum profile to be straightened at the set position on the roller conveyor belt, the roller conveyor belt is started, which moves the aluminum profile toward the frame. After the aluminum profile reaches the set position, the roller conveyor belt stops running. At the same time, the moving hydraulic cylinder is started, which pushes the clamping jaws close to the middle end of the aluminum profile. The clamping jaws clamp the tilted aluminum profile, making the tilted and irregularly shaped aluminum profile parallel to the roller conveyor belt. The distance measuring sensor on the moving component measures the distance between the two ends and the middle end of the aluminum profile to determine the shape of the aluminum profile bending, whether it is an arch or an inverted arch.

[0018] S2: Pressing the hydraulic cylinder pushes the connecting push plate to descend. After the electromagnetic component of the push plate is energized, it is magnetically connected to the connecting frame. After the connecting frame is fixed, it descends. After the gap formed between the inner positioning template blocks is aligned with one end of the aluminum profile, the moving component drives the connecting frame to move, so that the gap of the positioning template block is inserted into one end of the aluminum profile. The slight deformation of the aluminum profile causes the fixed frame connected to the positioning template block to deflect slightly, so that the positioning template block fits the aluminum profile better and increases the contact area. Multiple positioning template blocks are sequentially sleeved on both ends of the aluminum profile. The deformation of the aluminum profile causes the fixed frame to deflect and the pressing frame to rise and fall.

[0019] S3: The drive motor on the connecting frame starts, which drives the rotation of the double-ended lead screw. The movement of the double-ended lead screw causes the connecting slider to move. The connecting slider causes the connecting scissor frame to be stretched. After the connecting scissor frame is stretched, it causes the sliding slider to move, which causes the pressing frame to be pulled. The pressing frame causes the fixed frame to move, so that the positioning template block moves to a suitable position, which makes it easy to adjust the position of the positioning template block according to the degree of bending.

[0020] S4: The hydraulic cylinder pushes the support plate upward, the hydraulic cylinder presses the connecting frame downward, the electromagnetic component is de-energized, and after the pressing frame contacts the support plate below, the pressing frame is limited. The pressing hydraulic cylinder pushes the push plate downward, the push plate drives the pressing block to move downward on the connecting frame, the connecting spring is compressed, the pressing block presses the pressing frame, the pressing frame drives the fixed frame to descend, and after the fixed frame descends through the positioning template block, the upward-bent aluminum profile is pressed. At the same time, the positioning template block fits with the irregular aluminum profile to prevent the irregular aluminum profile from deforming. The reset spring resets. When it is necessary to press the middle, after the positioning template block moves to the middle of the aluminum profile, the pressing block can press the middle of the aluminum profile. The detection of the aluminum profile after pressing is completed by the cooperation of the capture camera and the distance sensor.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. By setting up a support device, the aluminum profile that needs to be straightened can be supported and fixed, and the irregular aluminum profile can be positioned. By pushing the hydraulic cylinder, the clamping jaws can clamp the tilted aluminum profile, so that the aluminum profile is deflected and becomes horizontal. By pushing the hydraulic cylinder to move the support plate between the rollers of the roller conveyor belt, it is easy to limit the pressing frame, so that the lower end of the pressing frame is consistent, and the straightening of the aluminum profile is completed.

[0023] 2. By setting up straightening components, irregularly shaped aluminum profiles can be straightened. The positioning template blocks adhere to the aluminum profiles, reducing deformation during straightening. The fixed frame deflects on the pressing frame, and the lifting and lowering of the pressing frame facilitates the alignment of the positioning template blocks with the aluminum profiles. By pressing the pressing frame, the rising and falling pressing frames maintain consistency, thus straightening the aluminum profiles by changing their position. The movement of the pressing frame allows for adjustments based on the location of aluminum profile deformation. This solves the technical problem of existing straightening machines being unable to straighten irregularly shaped louver aluminum profiles, leading to secondary defects such as surface indentations, localized dents, or contour deformation. These defects not only affect appearance quality but may also cause cross-sectional geometric accuracy deviations, resulting in secondary deformation during the straightening process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figures 1-8 An intelligent straightening machine for aluminum profiles includes a frame 1 and a roller conveyor belt 11 installed on the inner wall of the frame 1. The roller conveyor belt 11 conveys the aluminum profiles forward by rotating the rollers. A support device is fixedly installed on the outer surface of the frame of the roller conveyor belt 11, and a straightening component is fixedly installed on the inner wall of the frame 1.

[0035] like Figures 2-3In order to position the irregular aluminum profile of the louver, so that the aluminum profile, which is attached to the roller conveyor belt 11 and is inclined, is deflected, and the non-irregular part of the irregular aluminum profile can be parallel to the roller conveyor belt 11, which is convenient for subsequent straightening, the support device is located on the outer surface of the frame of the roller conveyor belt 11 and clamps and supports the aluminum profile conveyed by the roller conveyor belt 11. The support device includes clamping claws 21, which clamp and position the conveyed aluminum profile.

[0036] Specifically, in order not to affect the conveying of aluminum profiles, the support device also includes a movable hydraulic cylinder 2. The movable hydraulic cylinder 2 is fixedly installed on the outer surface of the frame of the roller conveyor belt 11. One end of the piston rod of the movable hydraulic cylinder 2 is fixedly installed on the outer surface of the clamping claw 21. By pushing the movable hydraulic cylinder 2, the clamping claw 21 can be brought closer to the middle section of the aluminum profile to complete the clamping and adjustment of the aluminum profile. The clamping claw 21 is a hydraulically driven or motor-driven claw, which makes it easy to control the clamping force and clamping speed.

[0037] Specifically, in order to limit the straightening components, a push hydraulic cylinder 22 is fixedly installed inside the frame of the roller conveyor belt 11. A support plate 23 is fixedly installed at one end of the piston rod of the push hydraulic cylinder 22. The push hydraulic cylinder 22 is distributed below the two ends and the middle end of the aluminum profile that need to be clamped, so as to provide auxiliary support for the straightening of the two ends or the middle end of the aluminum profile.

[0038] like Figures 4-8 As shown, in order to reduce the deformation caused by straightening the irregular aluminum profile, the straightening component is located on the inner top wall of the frame 1 and performs straightening work on the aluminum profile held by the support device. The straightening component includes a pressing device and a clamping device. The pressing device includes a pressing block 33. The descent of the pressing block 33 straightens the aluminum profile. The clamping device includes a positioning template block 59. The positioning template block 59 positions the aluminum profile.

[0039] Specifically, in order to adjust the pressing device and clamping device according to the required straightening position, the pressing device also includes a moving component 3. The moving component 3 is fixedly installed on the inner top wall of the frame 1. The moving component 3 consists of a frame installed on the inner top wall of the frame 1, a double threaded rod rotatably connected to the frame, a motor driving the double threaded rod to rotate, and a slider threadedly connected to the double threaded rod and slidably inserted into the frame. A pressing hydraulic cylinder 31 is fixedly installed on the lower surface of the slider of the moving component 3. A push plate 32 is fixedly installed on one end of the piston rod of the pressing hydraulic cylinder 31. The lower surface of the push plate 32 is fixedly installed on the upper surface of the pressing block 33. The pressing hydraulic cylinder 31 can adjust the position of the clamping device and push the pressing block 33 to descend to complete the straightening work.

[0040] Specifically, in order to clamp the aluminum profile, the clamping device also includes a connecting frame 4, which is slidably inserted into the outer surface of the push plate 32. A connecting spring 41 is fixedly installed on the outer surface of the connecting rod of the connecting frame 4. One end of the connecting spring 41 is fixedly installed on the lower surface of the push plate 32 to facilitate the reset of the connecting frame 4. An electromagnetic component 42 is fixedly installed on the upper surface of the push plate 32. The inner wall of the electromagnet of the electromagnetic component 42 is magnetically connected to the outer surface of the connecting rod of the connecting frame 4. The electromagnetic component 42 includes an isolation shell and an electromagnet installed in the shell to facilitate pushing the connecting frame 4 to descend as the push plate 32 descends.

[0041] Specifically, in order to adjust the position of the positioning template block 59 to adapt to the degree of bending of the aluminum profile, a double-ended lead screw 5 is rotatably connected to the outer surface of the connecting frame 4 via a bearing. A connecting slider 51 is threadedly connected to the outer surface of the double-ended lead screw 5. The inner wall of the connecting slider 51 is slidably connected to the outer surface of the guide rail of the connecting frame 4. A connecting scissor frame 52 is hinged to the outer surface of the connecting slider 51 via a pin. A sliding slider 53 is slidably sleeved on the outer surface of the double-ended lead screw 5. The sliding slider 53 is slidably inserted into the outer surface of the guide rail of the connecting frame 4 to complete the limiting. The outer surface of the sliding slider 53 is hinged to the middle pin of the connecting scissor frame 52. One end of the connecting scissor frame 52 is hinged to the outer surface of the connecting block of the double-ended lead screw 5 via a pin, so that one end of the connecting scissor frame 52 is limited, thereby allowing the connecting scissor frame 52 to unfold and converge. The movement of the connecting slider 51 can drive the sliding slider 53 to move in the same way using the connecting scissor frame 52.

[0042] Specifically, in order to drive the rotation of the double-ended lead screw 5, one end of the double-ended lead screw 5 located on one side is connected by a synchronous belt and a synchronous pulley for transmission. A drive motor 54 is fixedly installed on the outer surface of the connecting frame 4. One end of the output shaft of the drive motor 54 drives the rotation of the double-ended lead screw 5 through a bevel gear set.

[0043] Specifically, to facilitate the unfolding of the positioning template block 59, a movable slide 55 is fixedly installed on the outer surface of the pin connecting the scissor bracket 52. A pressing frame 56 is slidably inserted into the inner wall of the movable slide 55. Two sets of scissor brackets 52 on one side maintain the stability of the pressing frame 56's movement. A return spring 57 is fixedly installed on the outer surface of the movable slide 55. One end of the return spring 57 is fixedly installed on the outer surface of the pressing frame 56 to facilitate the return of the pressing frame 56, ensuring that multiple pressing frames 56 maintain the same height. This facilitates the positioning of the template block 59. The inner wall of the pressing frame 56 is hinged to the aluminum profile by a pin and a torsion spring to form a fixed frame 58. The torsion spring allows the fixed frame 58 to return to its original position after deflection. The inner wall of the fixed frame 58 is slidably inserted into the outer wall of the positioning template block 59. The outer surface of the fixed frame 58 is fixed to the positioning template block 59 by screwing bolts into the threaded grooves of the positioning template block 59. By unscrewing the bolts, the positioning template block 59 can be fixed in place, thereby allowing the positioning template block 59 to be disassembled and replaced with different positioning template blocks 59 to adapt to different irregular aluminum profiles.

[0044] Specifically, in order to inspect aluminum profiles, a distance sensor 6 is fixedly installed on the outer surface of the frame of the moving component 3, and a capture camera 61 is fixedly installed on the inner side wall of the frame 1.

[0045] The present invention discloses an aluminum profile straightening process using an intelligent aluminum profile straightening machine, comprising the following steps:

[0046] S1: After the worker places the aluminum profile to be straightened at the set position on the roller conveyor belt 11, the roller conveyor belt 11 is started to move the aluminum profile toward the frame 1. After the aluminum profile reaches the set position, the roller conveyor belt 11 stops running. At the same time, the moving hydraulic cylinder 2 is started to push the clamping jaw 21 close to the middle end of the aluminum profile. After the clamping jaw 21 clamps the inclined aluminum profile, the inclined irregular aluminum profile is parallel to the roller conveyor belt 11. The distance sensor 6 on the moving component 3 measures the distance between the two ends and the middle end of the aluminum profile to determine the shape of the aluminum profile bending, whether it is an arch or an inverted arch.

[0047] S2: Pressing the hydraulic cylinder 31 pushes the connecting push plate 32 to descend. After the electromagnetic component 42 of the push plate 32 is energized, it is magnetically connected to the connecting frame 4. After the connecting frame 4 is fixed, the connecting frame 4 descends. After the gap formed between the inner positioning template blocks 59 is aligned with one end of the aluminum profile, the moving component 3 drives the connecting frame 4 to move, so that the gap of the positioning template blocks 59 is inserted into one end of the aluminum profile. The slight deformation of the aluminum profile causes the fixed frame 58 connected to the positioning template blocks 59 to deflect slightly, so that the positioning template blocks 59 fit the aluminum profile better and increase the contact area. Multiple positioning template blocks 59 are sequentially sleeved on both ends of the aluminum profile. The deformation of the aluminum profile causes the fixed frame 58 to deflect and the pressing frame 56 to rise and fall.

[0048] S3: The drive motor 54 on the connecting frame 4 starts, which drives the rotation of the double-ended lead screw 5. The movement of the double-ended lead screw 5 causes the connecting slider 51 to move. The connecting slider 51 causes the connecting scissor frame 52 to be stretched. After the connecting scissor frame 52 is stretched, it causes the sliding slider 53 to move, which causes the pressing frame 56 to be pulled. The pressing frame 56 causes the fixed frame 58 to move, so that the positioning template block 59 moves to a suitable position, which is convenient to adjust the position of the positioning template block 59 according to the degree of bending.

[0049] S4: The hydraulic cylinder 22 pushes the support plate 23 to rise, the hydraulic cylinder 31 pushes the connecting frame 4 to fall, the electromagnetic component 42 is de-energized, and after the pressing frame 56 contacts the support plate 23 below, the pressing frame 56 is limited. The pressing hydraulic cylinder 31 pushes the push plate 32 to fall, and the push plate 32 drives the pressing block 33 to move downward on the connecting frame 4. The connecting spring 41 is compressed, and the pressing block 33 presses the pressing frame 56. The pressing frame 56 drives the fixed frame 58 to fall. After the fixed frame 58 falls through the positioning template block 59, the upward-bent aluminum profile is pressed. At the same time, the positioning template block 59 fits with the irregular aluminum profile to prevent the irregular aluminum profile from deforming. The return spring 57 returns to its original position. When it is necessary to press the middle, the positioning template block 59 moves to the middle of the aluminum profile, and the pressing block 33 presses the middle of the aluminum profile. The detection of the aluminum profile after pressing is completed by the cooperation of the capture camera 61 and the distance sensor 6.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

After the aluminum profile reaches the set position, the roller conveyor belt (11) stops running. At the same time, the moving hydraulic cylinder (2) is started to push the clamping jaw (21) close to the middle end of the aluminum profile. After the clamping jaw (21) clamps the inclined aluminum profile, the inclined irregular aluminum profile is parallel to the roller conveyor belt (11). The distance sensor (6) on the moving component (3) measures the distance between the two ends and the middle end of the aluminum profile to determine the shape of the aluminum profile bending, whether it is an arch or an inverted arch.

The movement of the double-headed screw (5) causes the connecting slider (51) to move. The connecting slider (51) causes the connecting scissor frame (52) to stretch. After the connecting scissor frame (52) is stretched, it causes the sliding slider (53) to move, which causes the pressing frame (56) to be pulled. The pressing frame (56) causes the fixed frame (58) to move, so that the positioning template block (59) moves to a suitable position, which is convenient to adjust the position of the positioning template block (59) according to the degree of bending. S4: The hydraulic cylinder (22) pushes the support plate (23) upward, the pressing hydraulic cylinder (31) pushes the connecting frame (4) downward, the electromagnetic component (42) is de-energized, after the pressing frame (56) contacts the support plate (23) below, the pressing frame (56) is limited, the pressing hydraulic cylinder (31) pushes the push plate (32) downward, the push plate (32) drives the pressing block (33) to move downward in the connecting frame (4), the connecting spring (41) is compressed, the pressing block (33) presses the pressing frame (56), the pressing frame (56) drives the fixed frame ( 58) The fixed frame (58) is lowered through the positioning template block (59), so that the upward-curved aluminum profile is pressed. At the same time, the positioning template block (59) fits with the irregular aluminum profile to prevent the irregular aluminum profile from deforming. The reset spring (57) resets. When it is necessary to press the middle, the positioning template block (59) moves to the middle of the aluminum profile. The pressing block (33) can press the middle of the aluminum profile. The detection of the aluminum profile after pressing is completed by the cooperation of the capture camera (61) and the distance sensor (6).
