Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window processing technology, and in particular to a sheet metal bending device for aluminum alloy door and window processing. Background Technology
[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions, and sashes. In the daily manufacturing process of doors and windows, the bending of aluminum alloy sheets is mostly done manually by workers using equipment.
[0003] In the prior art, Chinese Patent Publication No. CN222220794U discloses an aluminum alloy sheet bending device for aluminum alloy door and window production, relating to the field of aluminum alloy sheet bending technology. This utility model includes a main frame mechanism, which includes a worktable. A bending assembly is installed inside the worktable, and a limit assembly is installed on the top of the worktable. The bending assembly includes a motor, and a bidirectional threaded rod is fixedly connected to the right output end of the motor via a coupling. A top cutter is installed on the top of the worktable. This utility model, by setting up the bending assembly, specifically by starting the motor to drive the bidirectional threaded rod to rotate, simultaneously drives the top cutter to move upward, pushing the sheet upward. At the same time, the pressure plate moves downward through the action of the threaded rod, bending the sheet. This avoids manual bending, significantly reducing the workload of workers, greatly improving work progress, and significantly reducing physical harm to workers.
[0004] However, in actual use, the distance between the two pressure plates is fixed and not easy to adjust. When encountering boards of different widths, if the width of the board is less than the distance between the two pressure plates, the pressure plates may not be able to make enough contact with the board when pressing down, thus affecting the bending of the board. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this invention is to provide a sheet metal bending device for aluminum alloy door and window processing, which facilitates bending of sheets of different widths.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plate bending device for aluminum alloy door and window processing, comprising a support platform, a stabilizing frame fixedly connected to the top of the support platform, cylinders fixedly connected to both sides of the stabilizing frame, a telescopic rod fixedly connected to the output end of the cylinder, an adjusting arm fixedly connected to the bottom of the telescopic rod, a through hole provided inside the adjusting arm, a pressure-resistant rod fixedly connected to the inner wall of the stabilizing frame, an electric push rod fixedly connected to the bottom of the adjusting arm, a pressure rod fixedly connected to the bottom of the electric push rod, and a buffer layer fixedly connected to the outer surface of the pressure rod.
[0007] By adopting the above technical solution, when using the equipment, the operator places and fixes the plate in the middle, then activates the cylinder according to the width of the plate. The cylinder drives the telescopic rod to extend and retract appropriately, which in turn moves the adjusting arm. The two ends of the adjusting arm are supported by the anti-pressure rod. When moving, the perforated part slides on the surface of the anti-pressure rod, so that the distance between the two pressure rods corresponds to the width of the plate. After the pressure rods align with the top of both sides of the plate, the electric push rod extends to press down the pressure rods to bend the plate. The contact area between the bottom of the pressure rod and the plate is small, and the force is more concentrated. When in contact with the plate, the buffer layer plays a buffering role to prevent excessive impact force. The adjustment is flexible, which is convenient for bending plates of different widths and increases the processing range.
[0008] A further feature of this invention is that a buffer telescopic rod is fixedly connected to the bottom of the adjusting arm, and the bottom of the buffer telescopic rod is fixedly connected to the pressure rod.
[0009] By adopting the above technical solution, the buffer telescopic rod follows the lifting and extending of the pressure rod.
[0010] A further feature of this invention is that a groove is provided at the bottom of the support platform, and a hydraulic cylinder is fixedly connected to the inner wall of the groove.
[0011] By adopting the above technical solution, the hydraulic cylinder is activated during bending.
[0012] A further feature of this invention is that a hydraulic telescopic rod is fixedly connected to the output end of the hydraulic cylinder, and a lifting plate is fixedly connected to the bottom of the hydraulic telescopic rod.
[0013] By adopting the above technical solution, the hydraulic telescopic rod retracts, causing the lifting plate to rise automatically.
[0014] A further feature of this invention is that a bending mold is fixedly connected to the top of the lifting plate, and a moving groove is provided on the top of the support platform.
[0015] By adopting the above technical solution, when the bending die rises, it slides upward on the inner wall of the moving groove.
[0016] A further feature of this invention is that a sliding strip is fixedly connected to the inner wall of the moving groove, and an anti-slip groove is provided on the outer surface of the bending mold.
[0017] By adopting the above technical solution, the sliding resistance of the slider and anti-slip groove is increased, making the lifting and lowering more stable.
[0018] A further feature of this invention is that a second cylinder is fixedly connected to the top of the stabilizer, and a second telescopic rod is fixedly connected to the output end of the second cylinder.
[0019] By adopting the above technical solution, after the second cylinder is started, it drives the second telescopic rod to extend downward.
[0020] A further feature of this invention is that a top plate is fixedly connected to the bottom of the second telescopic rod, and a buffer pad is fixedly connected to the bottom of the top plate.
[0021] By adopting the above technical solution, the top plate is pressed down to fix the plate in the middle when it is placed, and the buffer pad cushions the pressure of the top plate when it is pressed down.
[0022] A further feature of this invention is that a wear-resistant pad is fixedly connected to the bottom of the buffer pad, and the bottom of the wear-resistant pad is provided with anti-slip protrusions.
[0023] By adopting the above technical solution, the wear-resistant pad prevents the buffer pad from being worn and has a high degree of flatness.
[0024] A further feature of this invention is that the number of the buffer telescopic rods is six, and the six buffer telescopic rods are grouped into sets of three.
[0025] By adopting the above technical solution, the buffer telescopic rod provides rigid support for the pressure rod during extension and retraction, thus preventing the pressure rod from swaying.
[0026] The beneficial effects of this utility model are:
[0027] 1. This utility model, through the coordinated arrangement of a support platform, a stabilizing frame, a cylinder, a telescopic rod, an adjusting arm, a perforation, a pressure-resistant rod, an electric push rod, a pressure rod, and a buffer layer, enables the device to be used by the operator. After the sheet material is placed and fixed in the middle, the cylinder is activated according to the width of the sheet material. The cylinder drives the telescopic rod to extend and retract appropriately, which in turn moves the adjusting arm. The two ends of the adjusting arm are supported by the pressure-resistant rod. When moving, the perforation slides on the surface of the pressure-resistant rod, so that the distance between the two pressure rods corresponds to the width of the sheet material. After the pressure rods align with the top sides of the sheet material, the electric push rod extends to press down the pressure rods to bend the sheet material. The contact area between the bottom of the pressure rod and the sheet material is small, resulting in more concentrated force. When in contact with the sheet material, the buffer layer acts as a buffer to prevent excessive impact. The device is flexible in adjustment and can be used to bend sheets of different widths, increasing the processing range.

This utility model, through the coordinated arrangement of the buffer telescopic rod, groove, hydraulic cylinder, hydraulic telescopic rod, lifting plate, bending die, moving groove, slide bar, anti-slip groove, second cylinder, second telescopic rod, top plate, buffer pad, and wear-resistant pad, enables the buffer telescopic rod to follow the lifting and extending of the pressure rod during use. When bending, the hydraulic cylinder is activated, the hydraulic telescopic rod retracts, and the lifting plate automatically rises. When the bending die rises, it slides upward on the inner wall of the moving groove. The slide bar and anti-slip groove increase resistance when sliding, making the lifting and lowering more stable. After the second cylinder is activated, it drives the second telescopic rod to extend downward. When the plate is placed, the top plate presses down for intermediate fixation. The buffer pad cushions the pressure of the top plate when it is pressed down, and the wear-resistant pad prevents the buffer pad from being worn, resulting in high flatness. The buffer telescopic rod provides rigid support for the pressure rod when it extends and retracts, preventing the pressure rod from shaking. Attached Figure Description
