Description

Technical Field

[0001] This invention relates to the field of aluminum profile bending technology, and more particularly to a bending equipment for aluminum profile processing. Background Technology

[0002] Aluminum profiles, with their advantages of being lightweight, high-strength, and corrosion-resistant, are widely used in construction, aerospace, and transportation. Bending is a key process in aluminum profile forming, and its processing accuracy and efficiency directly determine product quality. Currently, aluminum profile bending equipment has gradually replaced traditional manual bending methods, achieving automated processing. However, existing equipment still has many shortcomings. A newer method involves fixing the aluminum profile in a fixed mold and two bending molds. The fixed mold remains stationary, while one bending mold moves in a circular motion along with the other, causing the aluminum profile to undergo simultaneous arc deformation, thus achieving the bending purpose.

[0003] Aluminum profiles with different cross-sectional shapes, such as cylindrical and rectangular, as well as products with different bending diameters and specifications, are in extremely wide demand in actual production. Currently, most conventional aluminum profile bending equipment on the market uses a single fixed mold structure, which can only adapt to the processing of aluminum profiles with specific cross-sectional shapes and fixed bending diameters. Different types of profiles require the replacement of the entire mold set, which is not only cumbersome to operate but also significantly extends production preparation time, failing to meet the flexible processing needs of multi-specification, small-batch aluminum profiles. Therefore, it is necessary to design a bending equipment for aluminum profile processing to solve the above problems. Summary of the Invention

[0036] Before starting the equipment, the operator completes the initial settings through the control panel 8, and adjusts each component according to the shape, bending angle, bending radius, and other parameters of the aluminum profile to be processed. For the bending processing of cylindrical aluminum profiles, the cylindrical aluminum profile is first passed through the cylindrical sleeve 752 of the first clamping member 75. The jaws 755 on the mounting ring 754 are tightly attached to the surface of the aluminum profile under the action of spring force, realizing the stable clamping of the cylindrical aluminum profile and effectively preventing the aluminum profile from rotating circumferentially or shifting axially during the conveying and bending process. The control panel 8 precisely controls the third cylinder 58 to shorten, driving the first sliding frame 59, the first mounting platform 510, the first moving mold 513, and the second moving mold 514 to move backward. The first fixed mold 511 and the first moving mold 513 form a cylindrical channel on the lower side, and the second fixed mold 512 and the second moving mold 514 form a cylindrical channel on the lower side. At the same time, according to the preset bending radius of the aluminum profile, the control panel 8 precisely controls the action of the first cylinder 46 and the second cylinder 47 of the adjustment component 4: the first cylinder 46 extends and retracts, driving the first sliding plate 43 to move up and down along the vertical slide rail 42 to achieve vertical position calibration of the bending component 5; the second cylinder 47 extends and retracts, driving the mounting plate 45 to move back and forth along the horizontal slide rail 44 to complete the horizontal position adjustment of the bending component 5. The cylindrical channel formed by the first fixed mold 511 and the first moving mold 513 or the cylindrical channel formed by the second fixed mold 512 and the second moving mold 514 remains coaxially aligned with the center of the cylindrical sleeve 752, ultimately making the bending component 5 accurately positioned to the preset bending working position. The drive motor 710 is started via the control panel 8. The output shaft of the drive motor 710 drives the lead screw 79 to rotate at a constant speed through the coupling. The nut on the lead screw 79 drives the moving plate 72 and the first clamping member 75 to move synchronously, thereby driving the clamped cylindrical aluminum profile to move smoothly towards the bending assembly 5 until the preset bending position of the aluminum profile accurately reaches the mold between the molds of the bending assembly 5. The drive motor 710 then stops working, completing the feeding and positioning. When the aluminum profile reaches the preset feeding position, the fourth cylinder 64 of the feeding assembly 6 extends and retracts, driving the second sliding frame 62 to move back and forth along the second straight slide rail 61, adjusting the first feeding mold 69 and the second feeding mold 610 to the position corresponding to the aluminum profile.

[0037] During bending, the control panel 8 starts the servo motor 52. The output shaft of the servo motor 52 drives the rotating shaft 53 to rotate at a constant speed through the transmission action of the synchronous pulley 54 and the synchronous belt 55. The rotating shaft 53 synchronously drives the rotating frame 56 and the components on the frame to rotate together, so that the first moving mold 513 and the second moving mold 514 rotate smoothly around the axis of the rotating shaft 53. The first moving mold 513, the second moving mold 514 cooperate with the first fixed mold 511 and the second fixed mold 512 to apply a uniform bending force to the cylindrical aluminum profile, so that the aluminum profile undergoes uniform plastic deformation along the semi-cylindrical track of the mold and bends to the preset angle. During the bending process, the fifth cylinder 67 on the lower side extends synchronously, driving the connecting block 68, the lower guide rail 65, and the corresponding first feeding mold 69 and second feeding mold 610 to move to the left. The semi-cylindrical track of the feeding mold is tightly engaged with the side walls of the first fixed mold 511 and the second fixed mold 512, keeping the cylindrical aluminum profile in contact with the surface of the fixed mold, effectively preventing the aluminum profile from shifting, wrinkling, or cracking during bending. If bending is required on the other side of the aluminum profile, the motor of the rotating component 753 is started, which drives the cylindrical sleeve 752 to rotate through two meshing gears, thereby driving the cylindrical aluminum profile to rotate to a preset angle, and then repeating the above bending process to achieve multi-directional bending processing. During the bending process, the guide wheel 94 of the support component 9 is always in contact with the surface of the aluminum profile and rotates synchronously with the bending action of the aluminum profile, continuously providing stable support force to prevent the aluminum profile from sagging or shifting due to its own weight or bending force, further ensuring bending accuracy and surface flatness.

[0038] To address the bending requirements of irregularly shaped aluminum profiles, the first step is to adapt and clamp the molds, and adjust the bending position. Based on the cross-sectional dimensions and shape of the irregularly shaped aluminum profile, suitable special molds are installed in the rectangular mounting slots of the bending assembly 5 and the feeding assembly 6, as well as in the fixed clamping seat 761 and the movable clamping seat 764. This ensures that the molds are fully fitted to the cross-section of the irregularly shaped aluminum profile, preventing defects such as profile deformation and wrinkles during bending. Subsequently, by rotating the screw 78, the screw 78 moves the slide plate 74 to contact the fixed block 77. At this point, the first clamping member 75 is located at the rear, and the second clamping member 76 is located in the middle. Simultaneously, the control panel 8 controls the first cylinder 46 and the second cylinder 47 of the adjusting assembly 4 to work together, causing the bending assembly 5 to complete vertical and horizontal position adjustments. This aligns the clamping channel formed by the first fixed mold 511 and the first movable mold 513, or the clamping channel formed by the second fixed mold 512 and the second movable mold 514, on the upper side of the bending assembly 5 with the center of the second clamping member 76 of the feeding assembly 7. Simultaneously, the clamping distance of the feeding component 7 is adjusted to ensure it matches the length specifications of the irregular aluminum profile, preparing for subsequent clamping and feeding. The irregular aluminum profile is placed stably between the fixed clamping seat 761 and the movable clamping seat 764 of the second clamping component 76. The micro cylinder 765 is extended and retracted by the control panel 8, driving the movable clamping seat 764 to slide smoothly along the guide block 763 on the guide seat 762 until the movable clamping seat 764 and the matching mold on the fixed clamping seat 761 are completely fitted, achieving a firm clamping of the irregular aluminum profile. Then, the drive motor 710 is started, which drives the slide plate 74 and the second clamping component 76 to move through the lead screw 79, thereby driving the irregular aluminum profile to be conveyed towards the bending component 5 until the preset bending part reaches between the molds, at which point the drive motor 710 stops working. During the feeding process, the second clamping component 76 always maintains a firm clamping of the irregular aluminum profile to prevent the profile from shifting or shaking. The bending principle is the same as the bending process of the cylindrical aluminum profile.

[0039] After processing, the servo motor 52 reverses, driving the rotating frame 56 and the rotating shaft 53 back to their initial positions; the third cylinder 58 extends and retracts, driving the first sliding frame 59 to reset, separating the first fixed mold 511 from the first moving mold 513, and the second fixed mold 512 from the second moving mold 514; the fifth cylinder 67 of the feeding assembly 6 extends and retracts, driving the second sliding plate 66 to reset; the fourth cylinder 64 extends and retracts, driving the second sliding frame 62 to reset; the miniature cylinder 765 of the second clamping member 76 in the unloading assembly 7 resets, releasing the clamping of the irregular aluminum profile; the drive motor 710 reverses, driving the slide plate 74 and the above components back to their initial feeding positions.
