[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution for a bending processing device for the production of mirror aluminum plates: It includes a worktable 1, with two pairs of limiting rollers 101 symmetrically rotatably mounted at the center of the outer top surface of the worktable 1. Positioning rollers 102 and 103, parallel to each other, are fixedly mounted at the left and right ends of the outer top surface of the worktable 1, respectively. Rings 104 are rotatably mounted at the upper and lower ends of the outer circumferential surface of the positioning rollers 102. A U-shaped frame 105 is fixedly connected to the outer circumferential sidewalls of the two rings 104. A displacement component 3 is provided inside the worktable 1 to drive the U-shaped frame 105 to perform circular motion around the positioning rollers 102. The displacement component 3 includes a semi-circular through-type groove 301 opened on the outer top surface of the worktable 1. The upper and lower ends of the workbench 1 are rotatably mounted with a rotating shaft 302. The upper and lower ends of the outer circumferential surface of the rotating shaft 302 are respectively fixedly mounted with a circular plate 303 and a gear 304. The outer top surface of the circular plate 303 is fixedly mounted with a connecting plate 305. The top end of the connecting plate 305 passes through the slide groove 301 and is fixedly connected to the outer bottom surface of the U-shaped frame 105. The inner bottom surface of the workbench 1 is fixedly mounted with an electric push rod 306. The output end of the electric push rod 306 is fixedly mounted with a straight plate 307. The outer wall of the straight plate 307 near the gear 304 is fixedly mounted with a rack 308. The rack 308 and the gear 304 are meshed. The inner bottom surface of the workbench 1 is fixedly mounted with a U-shaped slider 309. The straight plate 307 is slidably sleeved in the inner side of the U-shaped slider 309.

[0028] In practical application, the aluminum plate is first placed between two pairs of limiting rollers 101. The end that needs to be bent is then passed through the inside of the U-shaped frame 105. Next, the electric push rod 306 is activated to drive the straight plate 307 to slide inside the U-shaped slider 309. First, the rack 308 drives the gear 304 to rotate, then the rotating shaft 302 drives the circular plate 303 to rotate. Then, the connecting plate 305 slides inside the groove 301. This allows the U-shaped frame 105 to perform a semi-circular motion around the positioning roller 102 as needed, thereby bending the aluminum plate along the positioning roller 102. This enables bending operations of different curvatures on the aluminum plate according to different processing requirements, improving the applicability of the device. Furthermore, after bending the aluminum plate once, it is pushed to continue moving inside the U-shaped frame 105 for a second bending, thus satisfying the need for continuous multiple bending operations on the aluminum plate, increasing the flexibility of the device.

[0029] The U-shaped frame 105 is equipped with a reinforcing component 2 for limiting the aluminum plate. The reinforcing component 2 includes a U-shaped frame 201 inside the U-shaped frame 105. A guide roller 202 is fixedly installed on the inner side of the U-shaped frame 201. The upper and lower ends of the inner side of the U-shaped frame 105 are provided with through-type horizontal openings 203. The two ends of the U-shaped frame 201 slide on the inner side of the two sets of horizontal openings 203 through connecting rods. An electric push rod 204 is fixedly installed on the outer wall of the side of the U-shaped frame 105 away from the positioning roller 102. The output end of the electric push rod 204 extends into the interior of the U-shaped frame 105 and is fixedly connected to the outer wall of the U-shaped frame 201. Slide rods 205 are fixedly installed at both ends of the outer wall of the U-shaped frame 201. One end of the two slide rods 205 extends to the outer wall of the U-shaped frame 105.

[0030] Furthermore, when the end of the aluminum plate that needs to be bent moves into the interior of the U-shaped frame 105, the electric push rod 204 is activated to drive the U-shaped frame 201 to move inside the U-shaped frame 105. With the assistance of the transverse opening 203 and the connecting rod, the stability of the movement of the U-shaped frame 201 is ensured, thereby allowing the guide roller 202 to push the aluminum plate to fit tightly against the outer peripheral side wall of the positioning roller 102. This facilitates the bending of the aluminum plate according to the required curvature and also prevents the aluminum plate from shifting during bending, which would affect the bending effect.

[0031] Both ends of the outer circumferential surface of the positioning roller 2 103 are fixedly installed with rings 2 4. A U-shaped frame 3 401 is fixedly connected to the outer circumferential sidewalls of the two rings 2 4. A vertical plate 402 is provided inside the U-shaped frame 3 401. A positioning square plate 403 is fixedly installed on the outer wall of one end of the vertical plate 402, while a threaded rod 404 is rotatably connected to the other end. The upper and lower ends of the inner side of the U-shaped frame 3 401 have through-type horizontal openings 2 405. (U-shaped frame 2 201) Both ends of the sliding rod 404 are slidable within the two sets of horizontal openings 405 via movable blocks. One end of the threaded rod 404 extends to the outer wall of the U-shaped frame 401 and is fixedly mounted with a knob 406. The two ends of the vertical plate 402, located outside the threaded rod 404, are fixedly mounted with sliding rods 407. One end of the two sliding rods 407 extends to the outer wall of the U-shaped frame 401, and the two sliding rods 407 are threadedly fixed to the U-shaped frame 401 via positioning screws 408.

[0032] In specific operation, the screw rod 404 is rotated by turning the knob 406, which allows the vertical plate 402 to move along the inner side of the U-shaped frame 401 with the positioning square plate 403. With the assistance of the horizontal opening 405 and the moving block, the stability of the positioning square plate 403 is ensured, so that the positioning square plate 403 fits against the outer wall of the aluminum plate to fix it and cooperates with the guide roller 202 to fix the aluminum plate. Then, the positioning screw 408 is turned to fix the sliding rod 407 and the U-shaped frame 401 together with the screw thread to ensure the fixing effect of the positioning square plate 403, thereby preventing the aluminum plate from shifting during bending and affecting the bending effect.

[0033] The working principle of this utility model is as follows: When using it, the aluminum plate is first placed between two pairs of limiting rollers 101, and its two ends are placed and passed through the interior of U-shaped frame 105 and U-shaped frame 301 respectively.

[0034] At the same time, first turn the knob 406 to drive the threaded rod 404 to rotate, which drives the vertical plate 402 to move with the positioning square plate 403 inside the U-shaped frame 401, so that the positioning square plate 403 fits against the outer wall of the aluminum plate to limit and fix it.

[0035] At the same time, the electric push rod 204 drives the U-shaped frame 201 to move, so that the guide roller 202 pushes the aluminum plate to fit tightly against the positioning roller 102, which limits its position and makes it easier for the aluminum plate to be bent according to the required curvature.

[0036] Finally, the electric push rod 306 is activated to drive the straight plate 307 to slide inside the U-shaped slider 309. First, the rack 308 drives the gear 304 to rotate, and then the rotating shaft 302 drives the circular plate 303 to rotate. The connecting plate 305 slides inside the slide groove 301, driving the U-shaped frame 105 to make a semi-circular circumferential motion around the positioning roller 102. This allows the aluminum plate to be bent at different arcs along the positioning roller 102 according to different processing requirements.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
