[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] like Figure 1-Figure 4 As shown, the automatic bending machine with adjustable curvature includes a support platform 1, which is a rectangular body with a hollow interior and closed walls. A fixed plate 2 is fixedly connected to one side of the top of the support platform 1. The fixed plate 2 is fixedly connected to a side of the fixed plate 2 close to the inner side of the support platform 1. The output ends of the multiple groups of hydraulic rods 201 are hinged together with a group of bending plates 202, which are rubber elastic plates; the inner wall of the bottom of the support platform 1 is fixedly connected to a motor 3 and two groups of limit rods 303, the output end of the motor 3 is fixedly connected to a screw rod 301, and the screw rod 301 is threadedly connected to multiple groups of forming plates 30 2. Two groups of limit rods 303 are respectively located on both sides of the screw rod 301, and the forming plates 302 are slidably connected to the two groups of limit rods 303. One side of multiple groups of forming plates 302 is respectively provided with bending grooves 3021 of different curvatures. Multiple groups of forming plates 302 are equidistantly separated by partitions 305 to prevent misalignment between bending grooves 3021 of different curvatures. A through groove 101 is provided on the top of the support platform 1, and the top of the screw rod 301 passes through the through groove 101 and extends to the outside of the support platform 1; a blanking component 4 is provided inside the support platform 1, and the blanking component 4 is used to feed the aluminum material after bending.

[0024] like Figure 1 and Figure 2As shown, the blanking component 4 includes a cylinder 401, and a blanking trough 102 connected to the through groove 101 is provided on the top of the support platform 1. The bottom of the cylinder 401 is fixedly connected to the inner wall of the support platform 1 on one side of the blanking trough 102. The output end of the cylinder 401 is fixedly connected to a connecting block 402, and the top of the connecting block 402 is fixedly connected to a support plate 403. The support plate 403 is slidably connected to the inside of the blanking trough 102 to automatically unload the aluminum material, reduce the labor intensity of manual material collection, and improve work efficiency.

[0025] like Figure 1 As shown, two groups of support seats 5 are fixedly connected to the inner wall of the bottom of the support platform 1, and the top of the two groups of support seats 5 is fixedly connected with an inclined blanking plate 501, which is located below the blanking trough 102. A rubber pad 5011 is fixedly connected to the inner wall of the blanking plate 501, and a discharge trough 103 is provided on the side wall of the support platform 1. One end of the blanking plate 501 is connected to the bottom of the discharge trough 103. The bent aluminum material is fed through the blanking plate 501 and then taken out through the discharge trough 103, which improves the convenience of taking and storing, and requires manual labor to only load the material.

[0026] like Figure 1 and Figure 4 As shown, slide grooves 4031 are provided on both sides of the support plate 403, and an adjusting rod 404 is slidably connected inside the slide groove 4031. The top of the adjusting rod 404 is fixedly connected to a limit plate 405 that is in contact with the top wall of the support plate 403, and the bottom of the adjusting rod 404 is threadedly connected to a fixing bolt 406 that is in contact with the bottom of the support plate 403. The aluminum material is limited by the limit plates 405 on the two groups of adjusting rods 404, which facilitates the center alignment of the aluminum material and the press-bending groove 3021 on the forming plate 302. At the same time, the adjusting rod 404 is loosened by rotating the fixing bolt 406, and then the sliding adjusting rod 404 drives the limit plate 405 to move, which is convenient for limiting aluminum materials of different lengths.

[0027] like Figure 1 and Figure 4 As shown, two groups of sliding rods 4021 are fixedly connected to one side of the connecting block 402, and a support block 407 is fixedly connected to the bottom of one side of the discharge chute 102. The sliding rods 4021 are slidably connected to the support block 407. When the support plate 403 slides, the two groups of sliding rods 4021 are driven by the connecting block 402 to slide on the support block 407 to support the support plate 403, thereby improving the sliding stability.

[0028] like Figure 1 As shown, a support frame 304 is fixedly connected to one side of the top of the support platform 1, and the top of the screw rod 301 is rotatably connected to the inner wall of the support frame 304. The top of the screw rod 301 is supported by the support frame 304 to improve the stability of the screw rod 301 driving the forming plate 302 to rise and fall.

[0029] like Figure 1 and Figure 2 As shown, two groups of photoelectric sensors 306 are fixedly connected to the top of the support platform 1, and the center lines of the two groups of photoelectric sensors 306 are aligned. The two groups of photoelectric sensors 306 are respectively located on both sides of the through slot 101, and the height is the same as the thickness of the forming plate 302, which is convenient for controlling the motor 3 to stop and align the forming plate 302 with the bending plate 202.

[0030] In this application, the model of the photoelectric sensor 306 is Penfun HA-E3F-DS30C1.

[0031] The working principle of the present invention is as follows: when the user uses it, he moves the two sets of limit plates 405, adjusts the distance between the two sets of limit plates 405 to be the same as the length of the aluminum material, and the distance between the two sets of limit plates 405 and the midpoint of the bending groove is the same, and then the aluminum material is placed on the support plate 403 between the two sets of limit plates 405, and the aluminum material is positioned. Then, according to the curvature requirement of the bending, the forming plate 302 to be used is determined, and then the motor 3 is started, and the motor 3 drives the screw rod 301 to rotate, and the screw rod 301 drives the multiple sets of forming plates 302 to move upward, and the forming plates 302 move upward from the through groove 101. When the height of the top of the forming plate 302 moving out of the through slot 101 is sensed by the photoelectric sensor 306, the photoelectric sensor 306 controls the motor 3 to stop. At this time, the forming plate 302 is aligned with the bending plate 202. If the first forming plate 302 is not the forming plate 302 with the required curvature, the motor 3 is started again to drive the forming plate 302 to move upward, and the bending plate 202 moves to counteract the aluminum material, pushing the aluminum material to move and the forming plate 302 until the required forming plate 302 is aligned with the bending plate 202. Then, multiple groups of hydraulic rods 201 and 202 are started. 1 Push the bending plate 202 to move and press the aluminum material, then multiple groups of hydraulic rods 201 push the bending plate 202 to continue to apply pressure to the aluminum material, the bending plate 202 deforms and pushes the aluminum material to deform and fit into the bending groove 3021, bending the aluminum material into the required curvature. During bending, the side of the forming plate 302 away from the bending groove 3021 abuts against the inner wall of the through groove 101, improving the ability of the forming plate 302 to withstand extrusion. After waiting for a certain period of time, start the hydraulic rod 201 to drive the bending plate 202 to reset, and then start the cylinder 401. The cylinder 401 drives the aluminum placed through the connecting block 402 The support plate 403 of the material slides in the discharge chute 102, and the support plate 403 continues to move to the bottom of the bending plate 202, so that the aluminum material on the support plate 403 is against the bending plate 202. When the support plate 403 drives the aluminum material to be against the bending plate 202, the support plate 403 continues to move, and the bending plate 202 blocks the aluminum material, so that the aluminum material is separated from the support plate 403, falls into the discharge plate 501 through the discharge chute 102, and then slides out from the discharge chute 103, reducing the process of manual material removal, and only requires manual loading, reducing labor intensity and improving work efficiency.

However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
