[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To address the challenges posed by existing bending structures in practical applications, such as complex adjustment methods, mediocre stability, and difficulty in meeting intelligent manufacturing requirements, please refer to... Figure 1 - Figure 5 This embodiment provides the following technical solution:

[0029] A sheet metal multi-angle bending intelligent processing device includes a support base 1, a telescopic plate 103 installed in the middle of the support base 1, a first top rod 104 installed at the upper end of the telescopic plate 103, support frames 2 installed on both sides of the support base 1, a sheet metal part 4 to be processed installed in the middle of the support frame 2, and a lifting frame 3 installed above the support frame 2. A movable adjustment plate 301 is provided in the middle of the lifting frame 3, and a second top rod 307 is installed at the lower end of the movable adjustment plate 301. Through the double-layer adjustment, the position adjustment effect of the first top rod 104 and the second top rod 307 is better, adapting to different bending operations, with strong working stability, which is conducive to long-term operation.

[0030] In this embodiment, a servo motor 101 is installed on one side of the support base 1. The motor shaft of the servo motor 101 is connected to a threaded screw 108 via a coupling. The threaded screw 108 passes through the telescopic plate 103 and is threadedly connected to the telescopic plate 103. An integrally formed guide groove 109 is provided inside the support base 1. The telescopic plate 103 is slidably connected to the support base 1 via the guide groove 109. The servo motor 101 drives the threaded screw 108 to rotate, so that the telescopic plate 103 moves inside the support base 1.

[0031] In this embodiment, a first electric cylinder 105 is installed at both the front and rear ends of the telescopic plate 103. Both ends of the first electric cylinder 105 are movably connected to the first push rod 104 and the telescopic plate 103 respectively through connecting ears. A sliding bracket 107 is installed at the lower end of the telescopic plate 103, and a roller is installed at the lower end of the sliding bracket 107. A second electric cylinder 106 is installed between the sliding bracket 107 and the first electric cylinder 105. Both ends of the second electric cylinder 106 are movably connected to the first electric cylinder 105 and the sliding bracket 107 respectively through connecting ears. The telescopic plate 103 inside the support base 1 moves. During the movement, the positions of the first electric cylinder 105 and the second electric cylinder 106 above the telescopic plate 103 are displaced, thereby adjusting the specific position of the first push rod 104 and realizing multi-angle bending work.

[0032] In this embodiment, the lifting frame 3 is provided with an integrally formed limiting groove 308 inside. The movable adjustment plate 301 is slidably connected to the lifting frame 3 through the limiting groove 308. Two pull plates 302 are installed at the upper end of the lifting frame 3. Winches 304 are installed on both sides of the lifting frame 3. A wire rope 303 is installed between the winch 304 and the lifting frame 3. The winches 304 on both sides are used to wind and unwind the wire rope, so that the position of the movable adjustment plate 301 is in a stable state, and the position of the mounting box 305 at the lower end of the movable adjustment plate 301 is stable, so that the second top rod 307 can be extended for processing.

[0033] In this embodiment, a mounting box 305 is installed at the lower end of the movable adjustment plate 301, and an electric hydraulic cylinder 306 is installed at the lower end of the mounting box 305. The two ends of the electric hydraulic cylinder 306 are fixedly connected to the mounting box 305 and the second push rod 307, respectively. By adjusting the length of the electric hydraulic cylinder 306, the position of the second push rod 307 is lowered to perform bending processing.

[0034] Specifically, by placing the workpiece 4 to be processed inside the support frame 2, the positions of the support base 1 and the lifting frame 3 are adjusted according to the length of the workpiece 4, so that the support frame 2 adapts to the workpiece 4. According to the bending position, the winch 304 and the servo motor 101 are adjusted to adjust the positions of the moving adjustment plate 301 and the telescopic plate 103, thereby adjusting the positions of the first top rod 104 and the second top rod 307. After adjustment, according to the bending requirements, the telescopic electric cylinder 306 drives the second top rod 307 to descend for bending. By adjusting the first electric cylinder 105 and the second electric cylinder 106, multi-angle bending is performed in conjunction with the first top rod 104. Through the double-layer adjustment method, the position adjustment effect of the first top rod 104 and the second top rod 307 is better, adapting to different bending operations, with strong working stability, which is conducive to long-term operation.

[0035] To address the technical problem that existing bending structures generally lack functionality and cannot meet practical work requirements, please refer to [the relevant documentation / reference]. Figure 1 - Figure 3 The following technical solutions are provided:

[0036] In this embodiment, a fixing plate 102 is welded to the upper ends of both sides of the support base 1. A hydraulic cylinder 201 is installed above the fixing plate 102. A connecting frame 202 is installed at the upper end of the hydraulic cylinder 201. The connecting frame 202 is connected to the lifting frame 3 by fixing screws. By retracting the hydraulic cylinder 201, the hydraulic cylinder 201 drives the lifting frame 3 and the positioning pressure plate 203 to press down the plate to be processed 4, so that the position of the plate to be processed 4 is stable.

[0037] In this embodiment, a positioning pressure plate 203 is installed inside the support frame 2, and a connecting slide plate 204 is installed on the upper end of the positioning pressure plate 203. The connecting slide plate 204 is fixedly connected to the lifting frame 3. The positioning pressure plate 203 is used to fix the plate to be processed 4. The position of the lifting frame 3 is kept stable by the connecting slide plate 204, which can adapt to high-intensity work.

[0038] Specifically, after the plate to be processed 4 is installed, the hydraulic cylinder 201 is retracted, which drives the lifting frame 3 and the positioning pressure plate 203 to press down the plate to be processed 4, stabilizing its position. Furthermore, by installing directional wheels at the bottom of the support base 1, the plate to be processed 4 is subjected to pressure during bending, causing both ends of the plate to be processed 4 to retract, thereby pulling the support base 1 to perform movement and displacement work, thus improving the working efficiency. In addition, distance sensors can be added to both sides of the support base 1, which are connected to the servo motor 101 and the winch 304 via a PLC, thereby intelligently adjusting the positions of the first push rod 104 and the second push rod 307, improving work efficiency.

[0039] The intelligent processing flow for multi-angle bending of sheet metal includes the following steps:

[0040] The workpiece 4 to be processed is placed inside the support frame 2. The positions of the support base 1 and the lifting frame 3 are adjusted according to the length of the workpiece 4 to adapt the support frame 2 to the workpiece 4. Distance sensors are added to both sides of the support base 1, and a servo motor 101 and a winch 304 are connected via a PLC. This allows for intelligent adjustment of the positions of the first push rod 104 and the second push rod 307, improving work efficiency. After the workpiece 4 is installed, the hydraulic cylinder 201 is retracted. The hydraulic cylinder 201 drives the lifting frame 3 and the positioning pressure plate 203 to press down on the workpiece 4, stabilizing its position. The lifting frame 3 is kept stable by the connecting slide plate 204, adapting to high-intensity work. The winch 304 and the servo motor 101 are adjusted according to the bending position to adjust the positions of the moving adjustment plate 301 and the telescopic plate 103. The machine 101 drives the threaded screw 108 to rotate, causing the telescopic plate 103 to move inside the support base 1, thereby adjusting the position of the first push rod 104 and the second push rod 307. The winches 304 on both sides rewind and unwind respectively, so that the position of the moving adjustment plate 301 is in a stable state, and the position of the mounting box 305 at the lower end of the moving adjustment plate 301 is stable, so that the second push rod 307 can be extended for processing. After the adjustment is completed, according to the bending requirements, the telescopic electric cylinder 306 drives the second push rod 307 to descend for bending. By adjusting the first electric cylinder 105 and the second electric cylinder 106, in conjunction with the first push rod 104, multi-angle bending can be performed. Through the double-layer adjustment method, the position adjustment effect of the first push rod 104 and the second push rod 307 is better, adapting to different bending operations, with strong working stability, which is conducive to long-term operation.

[0041] Working principle: The workpiece 4 to be processed is placed inside the support frame 2. The positions of the support base 1 and the lifting frame 3 are adjusted according to the length of the workpiece 4 to adapt the support frame 2 to the workpiece 4. Distance sensors are added to both sides of the support base 1, connected to the servo motor 101 and the winch 304 via a PLC, allowing intelligent adjustment of the positions of the first push rod 104 and the second push rod 307. After the workpiece 4 is installed, the hydraulic cylinder 201 is retracted, causing the lifting frame 3 and the positioning pressure plate 203 to press down on the workpiece 4, stabilizing its position. The lifting frame 3 is kept stable by the connecting slide plate 204, adapting to high-intensity work. The winch 304 and the servo motor 101 are adjusted according to the bending position, causing the positions of the moving adjustment plate 301 and the telescopic plate 103 to be adjusted. 01 drives the threaded screw 108 to rotate, causing the telescopic plate 103 to move inside the support base 1, thereby adjusting the position of the first push rod 104 and the second push rod 307. The winches 304 on both sides rewind and unwind respectively, so that the position of the moving adjustment plate 301 is in a stable state, and the position of the mounting box 305 at the lower end of the moving adjustment plate 301 is stable, so that the second push rod 307 can be extended for processing. After adjustment, according to the bending requirements, the telescopic electric cylinder 306 drives the second push rod 307 to descend for bending. By adjusting the first electric cylinder 105 and the second electric cylinder 106, in conjunction with the first push rod 104, multi-angle bending can be performed. Through the double-layer adjustment method, the position adjustment effect of the first push rod 104 and the second push rod 307 is better, adapting to different bending operations, with strong working stability, which is conducive to long-term operation.
