[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Figure 1-Figure 4 The following is a schematic diagram of the entire structure of a bending device for aluminum alloy door and window profiles of the utility model. Figure 1-Figure 4A bending device for aluminum alloy door and window profiles in this embodiment includes a processing table 100 for placing aluminum alloy door and window plates, a supporting frame 200 is fixed on one side of the processing table 100, a top plate 210 is fixed on the top of the supporting frame 200, a pressing device 300 is arranged at the bottom of the rear end of the top plate 210, which can move downward and press against the front end of the top of the processing table 100, a plate limiting mechanism 400 is arranged on one side of the supporting frame 200 and is located in the front end direction of the processing table 100, a cross rail 500 is fixed at the bottom of the top plate 210, a slide seat 510 is slidably arranged at the bottom and inner side of the cross rail 500, and also includes a moving drive component 520 arranged on the cross rail 500 and capable of driving the slide seat 510 to move forward and backward, a hydraulic rod 530 is arranged at the bottom of the slide seat 510, a positioning plate 540 is arranged at the output shaft end of the bottom of the hydraulic rod 530, and the positioning plate 540 is perpendicular to the front end of the processing table 100.

[0023] The pressing device 300 includes a hydraulic rod 310 fixed to the bottom of the top plate 210, a pressure plate 320 fixed to the output shaft end of the bottom of the hydraulic rod 310, and a rubber pad 330 arranged at the bottom of the pressure plate 320. When in use, after the plate is placed, the pressure plate 320 is pushed down by the hydraulic rod 310, and the lower plate and the edge of the plate to be bent are pressed and fixed with the cooperation of the rubber pad 330, and the rubber pad 330 can prevent the pressure plate 320 from causing surface pressure damage to the plate, so that the positioning plate 540 can be convenient for applying pressure to the plate to bend.

[0024] The plate limiting mechanism 400 includes a mounting plate 410 fixed to one side of the support stand 200, a plurality of positioning sleeves 420 fixed to the mounting plate 410, a guide rod 430 slidably matched to the inner side of the positioning sleeve 420 and penetrating the front and rear ends of the mounting plate 410, a baffle 440 perpendicular to the front end direction of the mounting plate 410 and fixedly connected to the front end of the guide rod 430, a threaded screw 450 threadedly connected to the mounting plate 410 through a ball nut and rotatably connected to the baffle 440 through a bearing at the front end, and a hand wheel fixed to the rear end of the threaded screw 450. 460. Since the distance between the bending line of the plate and the front end of the plate is fixed, in order to position the bending line of the plate and adjust the angle, the hand wheel 460 and the threaded screw 450 are rotated, and the baffle 440 is adjusted forward and backward with the cooperation of the guide rod 430, the positioning sleeve 420 and the nut. After the adjustment is completed, the front end of the plate can directly abut against the baffle 440, so that the bending line is just at the front end edge of the processing table 100. There is no need to make adjustments for subsequent operations of the same size, and the plate position can be directly and quickly positioned, which is simple and practical.

By setting the arc chamfer 5401 on one side of the bottom of the positioning plate 540, the positioning plate 540 can be effectively prevented from causing pressure damage and scratches on the surface of the plate when downward pressure is applied, so that the plate can be gradually bent linearly, ensuring the bending quality of the plate. Specifically, when in use, the servo motor 5202 can drive the threaded screw 5201 to rotate, and with the cooperation of the track and the nut, drive the slide 510 and the positioning plate 540 to move back and forth and fine-tune until the distance between the vertical surface of the front end of the positioning plate 540 and the vertical surface of the front end of the processing table 100 is matched with the thickness of the plate. Then, the hydraulic rod 2 530 pushes the positioning plate 540 downward and applies vertical pressure to the bending line of the plate, thereby achieving the purpose of bending the plate, so that the bending device can flexibly fine-tune the plate pressure folding line according to the actual size specifications of the plate, avoiding the problem of extrusion deformation or obvious surface scratches caused by the bending of the plate due to the large thickness of the plate, thereby improving the processing efficiency and finished product quality of the plate.

[0027] It can be understood that, on the basis of the above-mentioned embodiment, in order to further improve the ease of use of the bending device, specifically, a control display 600 is also provided on one side of the outer wall of the cross rail 500, which is respectively connected to the hydraulic rod 1 310, the hydraulic rod 2 530 and the servo motor 5202 signals. The drive unit of the bending device can be integrated and uniformly controlled through the control display 600. At the same time, the distance between the positioning plate 540 and the processing table 100 can be clearly displayed through the control display 600, making the operation more convenient.

[0028] In summary, the bending device of an aluminum alloy door and window profile in this embodiment can adjust the positions of the plate limiting mechanism 400 and the front end baffle 440 in advance when in use, and then place the plate on the processing table 100 so that the front end of the plate is positively abutted against the baffle 440, and then the hydraulic rod 1 310 pushes the pressure plate 320 down and presses and fixes the plate and the edge of the plate to be bent, and then the mobile drive assembly 520 drives the slide 510 and the positioning plate 540 to move back and forth and fine-tune until the distance between the front end vertical surface of the positioning plate 540 and the front end vertical surface of the processing table 100 is matched with the thickness of the plate, and then the hydraulic rod 2 530 pushes the positioning plate 540 downward and applies vertical pressure to the bending line of the plate, thereby achieving the purpose of bending the plate, so that the bending device can flexibly fine-tune the plate pressure folding line according to the actual size specifications of the plate, avoiding the problem of extrusion deformation or obvious scratches on the surface caused by the bending of the plate due to the large thickness of the plate.
