[0021] Such as Figure 1 、 2 、3, 4 show, a bending device for processing aluminum single plates, including a processing table 1, both sides of the upper surface of the processing table 1 are fixedly installed with side plates 3, between the two side plates 3, a top plate 5 is fixedly installed at the top, a guide plate 7 is slidably installed between the two side plates 3, the lower surface of the guide plate 7 is fixedly installed with a bending knife 10, the upper surface of the top plate 5 is fixedly installed with a first hydraulic cylinder 6, the output end of the first hydraulic cylinder 6 is arranged on the upper surface of the guide plate 7, the upper surface of the processing table 1 is provided with a positioning assembly 2, the other side of the upper surface of the processing table 1 is slidably installed with a limiting plate 8, and a bending support frame 14 is fixedly installed on the upper surface of the processing table 1, and the bending support frame 14 is located directly below the bending knife 10.

[0022] Such asFigure 1 , 4 As shown in 4 , on one side of the two side plates 3 close to each other, a first sliding groove 4 is provided. At both ends of the guiding plate 7, a first sliding block 9 is fixedly installed. The first sliding block 9 is slidably installed inside the first sliding groove 4. By slidably installing the first sliding block 9 inside the first sliding groove 4, the stability can be better when the guiding plate 7 moves.

[0023] As Figure 3 shown in Figure 3 , on the upper surface of the processing table 1, a second sliding groove 11 is provided. On the lower surface of the limiting plate 8, a second sliding block 12 is fixedly installed. The second sliding block 12 is slidably installed inside the second sliding groove 11. On the side of the processing table 1, a second hydraulic cylinder 13 is fixedly installed. The output end of the second hydraulic cylinder 13 is arranged on the side of the second sliding block 12. By the telescopic movement of the output end of the second hydraulic cylinder 13, at this time, the second sliding block 12 can be driven to slide inside the second sliding groove 11. At this time, the limiting plate 8 can be pushed to move forward. Move the limiting plate 8 to a suitable distance from the bending support frame 14. At this time, by placing the aluminum single plate to be bent on the upper surface of the bending support frame 14 and making one end of the aluminum single plate fit on the surface of the limiting plate 8, the distance between the limiting plate 8 and the bending support frame 14 is the bending position of the aluminum single plate, so as to ensure the accuracy of the bending position of the aluminum single plate.

[0024] As Figure 2 , 5 shown in 5 , the positioning assembly 2 includes two installation grooves 207 which are respectively provided on the side surfaces of the side plates 3. A rotating shaft 208 is rotatably installed between the inner side walls on both sides of the two installation grooves 207. On the side surfaces of the two rotating shafts 208, a connecting rod 210 is fixedly installed. On the inner surface of the installation groove 207, a return spring 209 is fixedly installed. The top end of the return spring 209 is arranged on the side surface of the rotating shaft 208. At the top ends of the two connecting rods 210, a mounting plate 201 is fixedly installed. On both sides of the upper surface of the mounting plate 201, a sliding column 203 is fixedly installed. A pressing plate 202 is slidably installed in the middle of the sliding column 203. At the top end of the sliding column 203, a positioning plate 204 is fixedly installed. On the positioning plate 204, a lead screw 206 is installed through a lead screw nut 205. The lower end of the lead screw 206 is rotatably arranged on the upper surface of the pressing plate 202.

The aluminum single plate is arranged between the pressing plate 202 and the mounting plate 201, playing a role in fixing the aluminum single plate and ensuring the accuracy of the position of the aluminum single plate when it is bent.

[0025] The working principle of the bending device for aluminum single plates:

[0026] When in use, when it is necessary to bend the aluminum veneer, first, the output end of the second hydraulic cylinder 13 expands and contracts. At this time, it can drive the second slider 12 to slide inside the second chute 11. At this time, it can push the limit plate 8 to move forward, and move the limit plate 8 to a suitable distance from the bending support frame 14. At this time, place the aluminum veneer to be bent on the upper surface of the bending support frame 14, and attach one end of the aluminum veneer to the surface of the limit plate 8. At this time, the distance between the limit plate 8 and the bending support frame 14 is the bending position of the aluminum veneer, so as to ensure the accuracy of the bending position of the aluminum veneer. At this time, the staff rotates the screw rod 206, so that the screw rod 206 cooperates with the screw rod sleeve 205 to move downward. At this time, it can drive the pressing plate 202 to move downward, so that the pressing plate 202 fits on the upper surface of the aluminum veneer, and the aluminum veneer is arranged between the pressing plate 202 and the mounting plate 201, playing a role in fixing the aluminum veneer and ensuring the accuracy of the position of the aluminum veneer during bending. At this time, the output end of the first hydraulic cylinder 6 expands and contracts. At this time, it can drive the guide plate 7 to move downward, so that the folding knife 10 also moves downward to bend the aluminum veneer. And because a rotating shaft 208 is rotatably installed between the inner walls of both sides of the installation groove 207, connecting rods 210 are fixedly installed on the sides of both rotating shafts 208, and a return spring 209 is fixedly installed on the inner surface of the installation groove 207. The top of the return spring 209 is arranged on the side of the rotating shaft 208, and the tops of the two connecting rods 210 are fixedly installed with a mounting plate 201, which can make the mounting plate 201 flip under the action of an external force, and at the same time will not affect the flipping of the aluminum veneer and will not affect the bending of the aluminum veneer. This device can ensure the stability of the aluminum veneer and the efficiency of bending the aluminum veneer when bending the aluminum veneer.

For those of ordinary skill in the art, based on the above description, other different forms of changes or modifications can be made. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present utility still fall within the protection scope of the present utility.
