Description

Technical Field

[0001] This utility model relates to the field of distribution box processing technology, specifically to a distribution box plate bending device. Background Technology

[0002] A distribution box is a low-voltage distribution box that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring standards. It integrates multiple electrical components, such as circuit breakers, contactors, and discharge tubes, enabling centralized control, protection, and monitoring of the power system.

[0003] When processing the distribution box, the four sides of the cut iron plate need to be bent. Currently, the bending is done manually by placing the plate at the bending point. During the bending process, the plate bends upwards at one end under pressure, and the worker needs to hold it and move it upwards. Then, the other three sides are processed in the same way. During the operation, the worker needs to be close to the dangerous area of ​​the machine. If the operation is not done properly or the machine malfunctions, it is difficult to operate manually, especially for some large or thick plates. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a technical solution: a power distribution box panel bending device, comprising: a main frame 1, a lifting and lowering pressing plate 3 on one side of the main frame 1, a supporting platform 2 fixedly connected below the pressing plate 3, forming a bending space between the pressing plate and the supporting platform; a limiting movable plate 6 placed in the middle of the main frame 1, and a first linear module 7 for driving the limiting movable plate 6 to move below the limiting movable plate 6; a material picking component placed on the outside of the main frame 1, the material picking component including a horizontally movable limiting block 16, an arc-shaped limiting rod 18 slidably arranged in the middle of the limiting block 16, a servo motor 19 fixedly connected to the top of the arc-shaped limiting rod 18, and an electromagnet 15 fixedly connected to the output end of the servo motor 19 for adsorbing and rotating the workpiece; and a limiting frame 13 placed on one side of the main frame 1 for preventing the material to be processed.

[0024] It should be noted that this utility model is equipped with a controller and an operation panel. The linear module is a lead screw linear module. The cut iron plates are stacked on top of the limiting frame 13. The second linear module 9 moves the limiting block 16 through the connecting slide rod 11. The limiting block 16 moves the electromagnet 15 below the limiting frame 13 through the arc-shaped limiting rod 18. When the electromagnet 15 is energized, it attracts the bottom iron plate. The second linear module 9 moves the connecting slide rod 11 through the connecting plate 10. The connecting slide rod 11 moves through the limiting block 16 and the arc-shaped limiting rod 18, causing the iron plate to bend. The point is concentric with the arc-shaped limiting rod 18. The arc-shaped limiting rod 18 places one end of the iron plate on the top of the support platform 2 through the electromagnet 15. One end of the iron plate contacts the limiting movable plate 6. The pressing plate 3 presses downward against the support platform 2, and the iron plate folds upward, causing the arc-shaped limiting rod 18 to move downward. When the support platform 2 separates from the pressing plate 3, the arc-shaped limiting rod 18 drives the electromagnet 15 to reset. The arc-shaped limiting rod 18 rotates the iron plate through the electromagnet 15, and so on, bending the four sides in a cycle. Then, the workpiece is removed by the unloading robot, and the automated processing of the workpiece is completed in this cycle.

[0025] Please see Figure 3 As shown, a lifting hydraulic cylinder 4 is fixedly connected to the inner side of the main frame 1, and the output end of the lifting hydraulic cylinder 4 is fixedly connected to the pressing plate 3.

[0026] It should be noted that the lifting hydraulic cylinder 4 of this utility model drives the pressing plate 3 to rise and fall, thereby realizing the contact and extrusion between the pressing plate 3 and the support platform 2. The workpiece is extruded and bent into shape by forming a bending space between the pressing plate and the support platform.

[0027] Please see Figure 3 As shown, the first linear module 7 is fixed to the inner wall of the main frame 1. A supporting hydraulic cylinder 8 is fixed to the moving slide of the first linear module 7. A supporting guide rail 5 is fixed to the output end of the supporting hydraulic cylinder 8. The limiting movable plate 6 is detachably installed on the top of the supporting guide rail 5.

[0028] It should be noted that this utility model adjusts the height of the support guide rail 5 by supporting the hydraulic cylinder 8, thereby adjusting the height of the limiting movable plate 6 by supporting the guide rail 5. The first linear module 7 drives the support hydraulic cylinder 8 to move, and the support hydraulic cylinder 8 drives the support guide rail 5 to move along the Y-axis, thereby realizing flexible adjustment according to the bending length of the workpiece.

[0029] Please see Figure 2 , 4As shown, the material handling assembly also includes a second linear module 9 fixed inside the main frame 1. A connecting plate 10 is fixedly attached to the moving slide of the second linear module 9. A connecting slide rod 11 is fixedly attached to one side of the connecting plate 10. The connecting slide rod 11 passes through the middle of the main frame 1 and is slidably connected to the main frame 1. A limit block 16 is fixedly connected to the end of the connecting slide rod 11. A return spring 21 is sleeved on the outside of the arc-shaped limit rod 18 and below the limit block 16. A cylinder 17 is fixedly attached to the outside of the limit block 16 for pressing and fixing the arc-shaped limit rod 18. A groove for the servo motor 19 to move is provided in the middle of the limit frame 13. A bracket 12 is fixedly connected to the bottom of the limit frame 13. A height limit baffle 14 can be adjusted and installed on one side of the limit frame 13.

[0030] It should be noted that when the second linear module 9 of this utility model moves the connecting plate 10 and the connecting slide rod 11, the piston rod of the cylinder 17 presses into the limiting block 16 so that it contacts the arc-shaped limiting rod 18, thereby fixing the arc-shaped limiting rod 18 in the middle of the limiting block 16. When the electromagnet 15 moves to the groove in the middle of the limiting frame 13, the electromagnet 15 is energized and attracts the bottom iron plate. Because the gap between the bottom of the height limiting baffle 14 and the limiting frame 13 contains only one iron plate... Thickness, the second linear module 9 drives the limiting block 16 and electromagnet 15 to pull the bottom iron plate out from the limiting frame 13, place one end of the iron plate on the top of the support platform 2, and then press down through the pressing plate 3. The cylinder 17 retracts and stops pressing the arc-shaped limiting rod 18. The iron plate flips upward, and the iron plate drives the electromagnet 15 to slide upward. After the flip is completed, the servo motor 19 drives the iron plate to rotate through the electromagnet 15, thereby bending each side.
