Technical Field
[0001] This utility model relates to the field of power cabinet bending technology, specifically a power cabinet processing bending device. Background Technology
[0002] An electrical cabinet is a power distribution device that combines specific electrical components to achieve the required power distribution. It is usually made by stamping, punching, and bending strip-shaped or plate-shaped metal plates, and then welding the frame together. A bending device is required when bending the metal plates.
[0003] The bending device consists of a bending head, a hydraulic cylinder, and a placement table. By placing the metal plate on the placement table, the pressure plate presses and fixes the metal plate, and the hydraulic cylinder operates, the hydraulic rod pushes the bending head to bend the metal plate, thus achieving the bending of the electrical cabinet.
[0004] When processing power cabinets, metal plates need to be bent. During the bending process, the bending length needs to be determined, but the bending length is not easy to measure, which leads to inaccurate bending positions and affects bending accuracy. Therefore, a bending device for processing power cabinets is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a bending device for processing power cabinets.

The line is aligned with the zero mark of the ruler. A fixed frame is welded to the placement platform. A second sliding groove is opened on the side wall of the fixed frame, and a second slider is installed in the second sliding groove. A pressure plate is welded to the second slider. A hydraulic cylinder is welded to the fixed frame, and a hydraulic rod is connected to the bottom end of the hydraulic cylinder. The hydraulic rod passes through the top plate of the fixed frame and is fixedly connected to the pressure plate. By rotating the lead screw, the first slider drives the push plate to move horizontally. The push plate pushes the metal plate to move horizontally on the placement platform. The distance between the push plate and the edge of the placement platform is the bending length. The bending length can be quickly determined by observing the ruler. This mechanism can quickly determine the bending position of the metal plate, which is beneficial to improving bending accuracy.
[0007] Preferably, limiting components are symmetrically installed on the placement platform. The limiting components include a mounting plate with a guide hole and a guide rod passing through the guide hole. By installing the guide rod, the clamping plate moves horizontally and linearly under the guidance of the guide rod, which helps to place the metal plate horizontally with the edge of the placement platform.
[0008] Preferably, a limit block is welded to the top of the guide rod, and a clamping plate is welded to the other end of the guide rod. A spring is fixedly installed between the clamping plate and the mounting plate. The spring is sleeved around the guide rod. By installing the spring, the spring is compressed, and the spring exerts a clamping force on the metal plate, which is beneficial for horizontally limiting the metal plate.
[0009] Preferably, two sets of first movable plates are symmetrically welded to the side wall of the placement platform. Each first movable plate has a first movable groove, which is L-shaped. Two sets of second movable plates are symmetrically and rotatably mounted on the side wall of the placement platform. A rotating rod is fixedly welded between the two sets of second movable plates. A rod hole is provided inside the placement platform, through which the rotating rod passes. A motor is mounted on the side wall of the placement platform via a base. The output shaft of the motor is fixedly connected to the rotating rod. A second movable groove is provided inside the second movable plate, and a movable block is assembled within the second movable groove. A bending rod is rotatably mounted between the two sets of movable blocks. The bending rod is assembled within the two sets of first movable grooves. With the rotation of the two second movable plates, the bending rod moves along the first movable groove. The movable blocks at both ends of the bending rod slide within the second movable groove. The moving structure of the bending rod is a right-angle structure, enabling rapid bending of the metal plate. The metal plate is clamped and fixed on the placement platform, preventing the metal plate from warping during bending. Simultaneously, the bending rod maintains stable contact with the metal plate, which helps improve the bending quality.
[0010] The advantages of this utility model are:
[0011] 1. This utility model uses a lead screw to rotate, which drives the first slider to move the push plate horizontally. The push plate pushes the metal plate to move horizontally on the placement table. The distance between the push plate and the edge of the placement table is the bending length. The bending length can be quickly determined by observing the scale. This mechanism can quickly determine the bending position of the metal plate, which is conducive to improving bending accuracy. By installing a guide rod, the clamping plate always moves horizontally and linearly under the guidance of the guide rod, which is beneficial to make the metal plate and the edge of the placement table horizontally placed.
[0012] 2. This utility model uses a spring that is compressed to clamp the metal plate, facilitating horizontal positioning of the metal plate. Two second moving plates rotate, causing the bending rod to move along the first moving groove. Moving blocks at both ends of the bending rod slide within the second moving groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3As shown, a bending device for processing power cabinets includes a base 1. A first groove 2 is formed on the base 1. A lead screw 3 is rotatably mounted on the inner wall of the first groove 2 via a bearing. One end of the lead screw 3 passes through the side wall of the first groove 2 and is welded with a knob 4. A first slider 5 is assembled inside the first groove 2, and the first slider 5 is sleeved around the lead screw 3. The first slider 5 has a thread and slides with the lead screw 3 through the thread. A push plate 6 is welded to the top of the first slider 5. A scale 7 is fixedly mounted on the base 1, and the scale 7 and push plate 6 are placed horizontally. A placement platform 8 is welded to the base 1, and the edge line of the placement platform 8 is aligned with the zero point of the scale 7. The scale is aligned, and a fixing frame 9 is welded onto the placement platform 8. A second sliding groove 10 is provided on the side wall of the fixing frame 9, and a second slider 11 is installed in the second sliding groove 10. A pressure plate 12 is welded onto the second slider 11. A hydraulic cylinder 13 is welded onto the fixing frame 9, and a hydraulic rod 14 is connected to the bottom end of the hydraulic cylinder 13. The hydraulic rod 14 passes through the top plate of the fixing frame 9 and is fixedly connected to the pressure plate 12. Limiting components are symmetrically installed on the placement platform 8. The limiting components include a mounting plate 15, which has a guide hole. A guide rod 16 passes through the guide hole, and a limiting block 17 is welded to the top end of the guide rod 16. The other end of the guide rod 16 is welded with... There is a clamping plate 18, and a spring 19 is fixedly installed between the clamping plate 18 and the mounting plate 15. The spring 19 is sleeved around the guide rod 16. During operation, when processing the power cabinet, the metal plate needs to be bent. During the bending process, the bending length needs to be determined. The bending length is not easy to measure, which leads to inaccurate bending position and affects bending accuracy. By placing the metal plate on the placement platform 8, the metal plate is located between the two clamping plates 18. The clamping plates 18 move horizontally and linearly under the guidance of the guide rod 16. The spring 19 is compressed, and the spring 19 has a clamping force on the metal plate, so that the metal plate is horizontally placed with respect to the edge of the placement platform 8. Given the known bending length of the metal plate, the edge of the placement platform 8 is aligned with the zero mark of the scale 7. Rotating the knob 4 causes the lead screw 3 to rotate, and the first slider 5 on the lead screw 3 moves within the first groove 2. The first slider 5 drives the push plate 6 to move horizontally, and the push plate 6 pushes the metal plate horizontally on the placement platform 8. The distance between the push plate 6 and the edge of the placement platform 8 is the bending length. Through the operation of the hydraulic cylinder 13, the hydraulic rod 14 moves downward, and the hydraulic rod 14 drives the pressure plate 12 to move downward, thus achieving the fixed clamping of the metal plate. This mechanism can quickly determine the bending position of the metal plate, which is beneficial for improving bending accuracy.
[0021] Please see Figure 4As shown, two sets of first movable plates 20 are symmetrically welded to the side wall of the placement platform 8. Each first movable plate 20 has a first movable groove 21, which is L-shaped. Two sets of second movable plates 22 are symmetrically and rotatably mounted on the side wall of the placement platform 8. A rotating rod 23 is fixedly welded between the two sets of second movable plates 22. A rod hole is provided inside the placement platform 8, through which the rotating rod 23 passes. A motor 24 is mounted on the side wall of the placement platform 8 via a base. The output shaft of the motor 24 is fixedly connected to the rotating rod 23. A second movable groove 25 is provided inside the second movable plate 22. A movable block 26 is assembled inside the second movable groove 25. A bent rod 27 is rotatably mounted between the two sets of movable blocks 26, and the bent rod 27 is assembled within the two sets of first movable grooves 21. During operation, the bending process of the existing bending device is unstable, resulting in poor bending effect and affecting bending quality. By clamping and fixing the metal plate, the motor 24 rotates, which drives the two second moving plates 22 to rotate. The bending rod 27 on the second moving plate 22 is initially located at the top of the first moving groove 21. During the rotation of the second moving plate 22, the bending rod 27 moves along the first moving groove 21. The moving blocks 26 at both ends of the bending rod 27 slide in the second moving groove 25. The moving structure of the bending rod 27 is a right-angle structure, which realizes the rapid bending of the metal plate. The metal plate is clamped and fixed on the placement platform 8, which prevents the metal plate from warping during bending. At the same time, the bending rod 27 is in stable contact with the metal plate, which helps to improve the bending quality.
[0022] Working principle: When processing the power cabinet, the metal plate needs to be bent. During the bending process, the bending length needs to be determined, which is difficult to measure, leading to inaccurate bending positions and affecting bending accuracy. The metal plate is placed on the placement table 8, positioned between two clamping plates 18. Guided by the guide rod 16, the clamping plates 18 move horizontally and linearly, compressing the spring 19, which exerts a clamping force on the metal plate, ensuring the metal plate is horizontally positioned with respect to the edge of the placement table 8. Given the bending length of the metal plate, the edge of the placement table 8 is aligned with the zero mark of the scale 7. Rotating the knob 4 rotates the lead screw 3, causing the first slider 5 on the lead screw 3 to move within the first slide groove 2. The first slider 5 drives the push plate 6 to move horizontally, pushing the metal plate horizontally on the placement table 8. The distance between the push plate 6 and the edge of the placement table 8 is the bending length. The hydraulic cylinder 13 operates, causing the hydraulic rod 14 to move downwards. The hydraulic rod 14 drives the pressure plate 12 to move downward, thus fixing and clamping the metal plate. This mechanism can quickly determine the bending position of the metal plate, which is beneficial to improving bending accuracy. The bending process of the existing bending device is unstable, resulting in poor bending effect and affecting bending quality. By clamping and fixing the metal plate, the motor 24 rotates, which drives the two second moving plates 22 to rotate. The bending rod 27 on the second moving plate 22 is initially located at the top of the first moving groove 21. During the rotation of the second moving plate 22, the bending rod 27 moves along the first moving groove 21. The moving blocks 26 at both ends of the bending rod 27 slide in the second moving groove 25. The moving structure of the bending rod 27 is a right-angle structure, which realizes the rapid bending of the metal plate. The metal plate is clamped and fixed on the placement platform 8, which prevents the metal plate from warping during bending. At the same time, the bending rod 27 is in stable contact with the metal plate, which is beneficial to improving bending quality.
