Description

Technical Field

[0001] The invention relates to the technical field of metal sheet processing for a power distribution cabinet, and in particular to a metal sheet processing device for a power distribution cabinet. Background Art

[0002] The metal sheets used in the power distribution cabinet usually play an important role. The materials of metal sheets are various, and the common ones are stainless steel, galvanized steel plates, etc. Stainless steel has good corrosion resistance and can maintain stable performance in a relatively harsh environment. Metal sheets have many functions in the power distribution cabinet. According to the use scenario of the metal sheet, the metal sheet needs to be processed into a suitable shape;

[0003] When installing some parts in the distribution cabinet, L-shaped metal sheets are required. Therefore, the metal sheets need to be bent and then cut to form metal sheets of appropriate size and shape. However, the existing L-shaped metal sheets are usually bent on a hydraulic press and then moved to a cutting machine for cutting after bending. This method is more troublesome and greatly reduces the processing efficiency of the metal sheets. In addition, since the metal sheets used for general processing are longer, the metal sheets can be cut into multiple metal sheets. However, using two devices for processing greatly reduces the processing efficiency of the metal sheets. At the same time, during cutting, the debris generated by cutting will adhere to the metal sheets, resulting in the need to clean the metal sheets later, which is more troublesome. Therefore, it is necessary to design a processing equipment for metal sheets of distribution cabinets to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a metal sheet processing equipment for distribution cabinets is proposed.

After each cutting, the metal sheet can be automatically pushed a certain distance, so that a metal sheet can be quickly cut into multiple metal sheets of the same size, and the cut sheet can be separated from the debris generated by the cutting.

The one-way bearing is a kind of one-way bearing that can rotate freely in one direction and in the other direction.

When the first rack 17 moves up, the second gear 39 will drive the first rotating rod 9 to rotate. At the same time, the first rack 17 is shorter, so that before the pressure plate 16 contacts the metal sheet, the first rack 17 and the second gear 39 are no longer engaged. The first rotating rod 9 is connected to the threaded rod through the first transmission assembly 10. The first transmission assembly 10 includes a first sprocket arranged on the first rotating rod 9 and the threaded rod, and the two first sprockets are connected through a first chain transmission.

The second rotating rod 12 passes through the two fixed blocks 11, and a worm gear 13 is provided on the second rotating rod 12. The first rotating rod 9 is provided with a threaded layer, and the threaded layer is a threaded layer similar to that of a worm. The second rotating rod 12 is connected to the third rotating rod 21 through a second transmission assembly 22. The second transmission assembly 22 includes a second sprocket arranged on the second rotating rod 12 and the third rotating rod 21, and the two second sprockets are connected through a second chain transmission.

[0033] Among them, a clamping assembly is provided on the right side of the stopper, and the clamping assembly includes a connecting plate 26 arranged at the lower end of the stopper, and the connecting plate 26 is rotatably connected to the lower end of the baffle, and a torsion spring is provided on the rotating shaft where the connecting plate 26 is rotatably connected to the baffle, so that the clamping assembly can be reset, and a pneumatic telescopic plate 27 is fixedly connected to the right side of the connecting plate 26. Each time the pressing plate 16 moves down to the lowest end, the controller will control the pneumatic telescopic plate 27 to automatically operate, so that the two U-shaped blocks 18 and the cut metal sheet move to the right, and the upper end of the pneumatic telescopic plate 27 is fixedly connected with two U-shaped blocks 18. After a period of time, the controller will control the pneumatic telescopic plate 27 to contract, so that the two U-shaped blocks 18 are reset. During this period of time, the cut metal sheet will automatically fall down, and the inner tops of the two U-shaped blocks 18 are provided with electromagnets 28. A clamping plate 24 is provided in each of the two U-shaped blocks 18. The clamping plate 24 is made of magnetic material. When the electromagnet 28 is energized, a repulsive force is generated on the clamping plate 24. The two clamping plates 24 are elastically connected to the adjacent sides of the corresponding electromagnets 28 through multiple springs 25. The adjacent sides of the two U-shaped blocks 18 are commonly fixedly connected with an infrared sensor 19. When the metal sheet moves right to below the infrared sensor 19, the infrared sensor 19 generates an electrical signal and transmits it to the controller. The controller controls the electromagnet 28 to be energized, thereby causing the two clamping plates 24 to move downward to clamp the metal sheet. When the output shaft of the servo motor 36 rotates counterclockwise, the controller controls the electromagnet 28 to be powered off. A PLC control program is provided in the controller, and the servo motor 36, the pneumatic telescopic plate 27 and the electromagnet 28 are controlled by the PLC control program.

[0034] The present invention can explain its functional principle through the following operation mode: when processing the metal sheet, the metal sheet is placed between the two rectangular plates 2, so that the upper and lower ends of the metal sheet are in contact with the multiple conveying rollers 5, and the right end of the metal sheet is flush with the rightmost side of the stopper. At this time, the staff can control the two hydraulic rods 15 to stretch, so that the pressure plate 16 moves down. In the process of the pressure plate 16 moving down, since a one-way bearing is provided between the second gear 39 and the first rotating rod 9, when the first rack 17 moves down, the one-way bearing will automatically lock, and the rotation of the second gear 39 will not drive the first rotating rod 9 to rotate. When the pressure plate 16 moves down to be flush with the upper surfaces of the two U-shaped blocks 18, the first rack 17 is no longer meshed with the second gear 39;

[0035] When the pressing plate 16 moves down to a specified distance, the hydraulic rod 15 can be controlled to contract, so that the pressing plate 16 moves back. During the process of the pressing plate 16 moving back, when the first rack 17 is meshed with the second gear 39, the second gear 39 drives the first rotating rod 9 to rotate, thereby driving the threaded rod to rotate through the first transmission assembly 10, so that the pushing plate pushes the metal sheet to move right into the two U-shaped blocks 18. At this time, after the infrared sensor 19 senses the metal sheet, it controls the electromagnet 28 to be energized, so that the electromagnet 28 generates a repulsive force on the pressing plate 24, thereby pressing the metal sheet;

[0036] At this time, the staff can control the hydraulic rod 15 to stretch again, so that during the stretching process of the hydraulic rod 15, the pressing plate 16 will move downward, thereby bending the metal sheet on the right side of the stopper to 90 degrees, and during the bending process of the metal sheet downward, the two U-shaped blocks 18 will rotate downward;

[0037] After bending, the controller will automatically control the output shaft of the servo motor 36 to rotate clockwise and then counterclockwise, so that the saw blade 23 rotates. At the same time, the servo motor 36 drives the first gear 35 to rotate through the third transmission assembly 33, so that the first gear 35 drives the slider 38 mounting seat 30 to move forward to cut the metal sheet, thereby cutting the next L-shaped metal sheet. When the cutting is completed, the controller controls the output shaft of the servo motor 36 to rotate counterclockwise, so that the slider 38 drives the saw blade 23 and the mounting seat 30 to reset, and the controller controls the electromagnet 28 to cut off the power.

[0038] After the electromagnet 28 is powered off, the clamping plate 24 will be reset under the action of multiple springs 25. At this time, the controller will automatically control the pneumatic telescopic plate 27 to stretch, so that the cut metal sheet is away from the block. Then, under the action of gravity, the metal sheet falls on the inclined plate 20 and slides to the left (because the distance between the reset of the clamping plate 24 and the U-shaped block 18 is greater than the distance between the groove and the right side of the block, and the left side of the U-shaped block 18 is an inclined surface, so that the metal sheet can automatically fall on the inclined plate 20). When the metal sheet falls, the staff can control the hydraulic rod 15 to retract and reset, and the pneumatic telescopic plate 27 to retract and reset at the same time. According to the above method, one metal sheet can be processed into multiple L-shaped metal sheets.

[0039] Since the air pump is always in operation, when the metal sheet falls on the inclined plate 20, it will slide to the left to the flip plate 37, so that the air pump can blow away the metal sheet and the debris on the inclined plate 20. At the same time, when the first rotating rod 9 rotates, the second rotating rod 12 is driven to rotate by the worm gear 13, so that the third rotating rod 21 drives multiple flip plates 37 to rotate, so that the metal sheet can be flipped, and the airflow is used to blow away the debris on the metal sheet as much as possible. Since the flip plate 37 is also in a tilted state after being flipped, the flipped metal sheet will continue to slide to the left, and then fall into the outside through the opening 7 on the left for collection.

[0040] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
