Description

Technical Field

[0001] This invention relates to the field of plasma cutting technology, and in particular to a plasma cutting device for the production of electrical cabinets. Background Technology

[0002] In the manufacturing process of electrical cabinets, the precise and efficient opening and cutting of the cabinet panels is a key process. Currently, the industry has gradually adopted automated equipment to replace the traditional manual or semi-automatic processing methods.

[0003] The invention patent with authorization announcement number CN117340445B discloses an intelligent laser cutting device for switch cabinet panels. The device includes a base, which houses a No. 1 motor. The output of the No. 1 motor is fixedly connected to a No. 1 turntable. The upper part of the No. 1 turntable has several workstation slots, and the turntable also has circular slots corresponding to the workstation slots, as well as a material discharge channel. The circular slots are connected to the workstation slots, and each circular slot is equipped with a positioning mechanism. The material discharge channel is located inside the workstation slots. A feeding mechanism, a laser cutter, and a discharging mechanism are sequentially arranged around the circumference of the base. The feeding mechanism continuously moves the cabinet panel to the workstation, and then two cutting heads simultaneously cut the cabinet panel below it. Finally, the discharging mechanism lifts the cabinet panel and rotates it to discharge the material. This allows feeding, cutting, and discharging to be performed on the same turntable, forming a complete operation and improving work efficiency.

[0004] However, the above invention still has technical defects: 1. In order to achieve full automation, too many complex mechanisms with independent drives are integrated. The unloading mechanism needs to complete two actions: impacting the waste and lifting the workpiece. For this purpose, an expansion mechanism including a motor, worm gear, turntable, four-jaw chuck and external expansion rod is designed; 2. The loading mechanism uses a paddle to paddle the bottom workpiece from the bottom of the basket and uses a roller to lift the upper workpiece to reduce pressure. The paddle and the workpiece are in rigid contact. Although the upper workpiece is lifted when paddled, the workpiece surface may still be scratched during the paddle process, affecting the product appearance; 3. The size and shape of the workstation slot are fixed and cannot adapt to cabinet panels of different sizes or shapes. Therefore, a plasma cutting device for electrical cabinet production is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art, and to propose a plasma cutting device for the production of electrical cabinets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A plasma cutting device for electrical cabinet production includes a cutting table, two side supports fixed to one side of the cutting table, a pusher plate slidably connected between the two side supports, a connecting plate fixed to the side of the pusher plate away from the cutting table, a mounting plate fixed to the bottom of the connecting plate, a guide plate fixed to the bottom of the mounting plate, a storage frame fixed to the top of the cutting table, and the pusher plate sliding within the storage frame. A support frame is provided on the side of the storage frame away from the push plate. The support frame is rotatably connected to the cutting table via a second shaft. An installation slide rail is provided on the side of the support frame away from the second shaft. A first slide block is slidably connected to the top of the installation slide rail. A second slide block is slidably connected to the top of the first slide block. A plasma cutting mechanism is fixed to one side of the second slide block. A central mounting bracket is fixedly connected to the bottom of the top plate of the cutting table. A motor is fixedly connected to the top of the central mounting bracket. A second gear is fixedly connected to the output shaft of the motor. A first gear meshes with the outer wall of the second gear. The first gear is rotatably connected to the central mounting bracket via a first shaft. Two transmission wheels are arranged above the first shaft. Belts are fitted around the outer walls of the two transmission wheels. The end of the first shaft is fixedly connected to one of the transmission wheels. A missing gear is fixedly connected to the other transmission wheel via a shaft. The missing gear is rotatably connected to the bottom of the cutting table via a shaft. A full gear meshes with the outer wall of the missing gear.

[0007] Preferably, the gear is rotatably connected to the bottom of the cutting table via a shaft and is fixedly connected to a bearing rod, with the same annular spring fixedly connected to both sides of the bearing rod.

[0008] Preferably, a positioning rod is slidably connected to one side of the mounting plate, and the other end of the positioning rod is fixedly connected to the bottom of the cutting table. A return spring is arranged around the outer wall of the positioning rod, and the two ends of the return spring are fixedly connected to the cutting table and the mounting plate, respectively.

[0009] Preferably, a mounting rod is fixed to the outer wall of the first shaft, the mounting rod is located between the first gear and the transmission wheel, and a push rod is fixed to the end of the mounting rod away from the first shaft. The push rod is installed on the side facing the cutting table.

[0010] Preferably, a demolding rod is provided on the side of the bearing frame away from the storage frame. The demolding rod is rotatably connected to the support on the cutting table through a shaft. A gear is fixedly connected to the end of the shaft of the demolding rod. A rack is meshed on the outer wall of the gear. An inclined block is fixedly connected to the bottom end of the rack. A first spring is fixedly connected between the inclined block and the cutting table.

[0011] Preferably, a second gear is fixedly connected to the end of the second shaft, and a helical rack meshes with the outer wall of the second gear. The helical rack is slidably connected to the cutting table, and a second spring is fixedly connected between the helical rack and the cutting table.

[0012] Preferably, the support frame is provided with symmetrically distributed central sliding plates, the two central sliding plates are slidably connected to the cutting table, the bottom of the central mounting frame is fixedly connected to the unloading box, the middle of the unloading box is fixedly connected to the partition, and the partition is flush with the edge of the support frame.

A threaded rod is threadedly connected to the top of the discharge baffle, and the threaded rod is threadedly connected to the inside of the storage frame.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention, by setting adjustable push blocks, discharge baffles, and a central sliding plate, enables the device to quickly adapt to cabinet panels of different lengths, thicknesses, and widths, thus overcoming the shortcomings of traditional special-purpose machines that can only process products of a single specification.

[0015] Using a single power source to sequentially drive the feeding, demolding, and unloading actions replaces the design with multiple drives and complex independent mechanisms in the comparison document, significantly reducing the manufacturing cost and energy consumption of the equipment, reducing failure points, improving long-term operational stability and reliability, and simplifying maintenance.

[0016] The design incorporates a step-by-step process where waste material is first topped off and then the finished product is flipped over. The two are physically separated in a collection device, which effectively avoids waste residue, reduces the risk of damage to the cutting edges of the workpiece, and ensures product quality.

[0017] The entire process of the device, from feeding, centering, cutting to the sorting and collection of finished products and waste, is fully automated and requires no manual intervention. Through the intermittent transmission of missing and full gears and the cooperation of push rods and inclined planes, precise timing control between each process is achieved, ensuring a smooth and efficient production process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Reference Figure 1 - Figure 12A plasma cutting device for electrical cabinet production includes a cutting table 1. Two side supports 6 are fixedly connected to one side of the cutting table 1. A pusher plate 5 is slidably connected between the two side supports 6. A connecting plate 19 is fixedly connected to the side of the pusher plate 5 away from the cutting table 1. A mounting plate 20 is fixedly connected to the bottom of the connecting plate 19. A guide plate 23 is fixedly connected to the bottom of the mounting plate 20. A storage frame 2 is fixedly connected to the top of the cutting table 1. The pusher plate 5 slides within the storage frame 2. A support frame 8 is provided on the side of the storage frame 2 away from the push plate 5. The support frame 8 is rotatably connected to the cutting table 1 via the second shaft 39. A mounting slide rail 16 is provided on the side of the support frame 8 away from the second shaft 39. A first slide block 13 is slidably connected to the top of the mounting slide rail 16. A second slide block 15 is slidably connected to the top of the first slide block 13. A plasma cutting mechanism 11 is fixedly connected to one side of the second slide block 15. A central mounting bracket 17 is fixedly connected to the bottom of the top plate of the cutting table 1. A motor 34 is fixedly connected to the top of the central mounting bracket 17. A second gear 33 is fixedly connected to the output shaft of the motor 34. A first gear 31 meshes with the outer wall of the second gear 33. The first gear 31 is rotatably connected to the central mounting bracket 17 through a first shaft 32.

[0023] A positioning rod 21 is slidably connected to one side of the mounting plate 20. The other end of the positioning rod 21 is fixedly connected to the bottom of the cutting table 1. A return spring 22 is arranged around the outer wall of the positioning rod 21. The two ends of the return spring 22 are fixedly connected to the cutting table 1 and the mounting plate 20, respectively.

[0024] A mounting rod 25 is fixedly connected to the outer wall of the first shaft 32. The mounting rod 25 is located between the first gear 31 and the transmission wheel 29. A push rod 24 is fixedly connected to the end of the mounting rod 25 away from the first shaft 32. The push rod 24 is installed on the side facing the cutting table 1.

[0025] A demolding rod 10 is provided on the side of the support frame 8 away from the storage frame 2. The demolding rod 10 is rotatably connected to the support on the cutting table 1 via a shaft. A gear 37 is fixedly connected to the end of the shaft of the demolding rod 10. A rack 36 meshes with the outer wall of the gear 37. An inclined block 35 is fixedly connected to the bottom end of the rack 36. A first spring 42 is fixedly connected between the inclined block 35 and the cutting table 1.

[0026] In this embodiment, the motor 34 then starts, driving the first gear 31 and the first shaft 32 to rotate via the second gear 33. This causes the mounting rod 25 on the first shaft 32 to slide along the guide plate 23 via the push rod 24. The mounting plate 20, connecting plate 19, and push plate 5 push the bottom cabinet panel out of the storage frame 2. The two centering slide plates 9 limit the automatic centering. Then, the first slide block 13, along with the second slide block 15, slides along the mounting slide rail 16. The second slide block 15, along with the plasma cutting mechanism 11, slides along the first slide block 13. The plasma cutting mechanism 11 slides on the second slide block 15, opening a window in the cabinet panel. After cutting, the mounting rod 25 rotates with the push rod 24 to below the inclined block 35. The push rod 24 abuts against the inclined block 35 and pushes the inclined block 35 upward, thereby driving the demolding rod 10 to rotate toward the support frame 8 through the gear 1 37. The demolding rod 10 separates the plate cut in the middle of the support frame 8. The cut plate falls to one side of the partition 12 in the material box 14. When the mounting rod 25 rotates to below the angled rack 41, it also pushes the angled rack 41 upward. Through the gear 2 40, it drives the second shaft 39 and the support frame 8 to rotate downward, dropping the electrical cabinet plate into the material box 14, which is the other side of the partition 12.

[0027] Two transmission wheels 29 are arranged above the first shaft 32. The outer walls of the two transmission wheels 29 are fitted with belts 30. The end of the first shaft 32 is fixedly connected to one of the transmission wheels 29. The other transmission wheel 29 is fixedly connected to a missing gear 38 through a shaft. The missing gear 38 is rotatably connected to the bottom of the cutting table 1 through a shaft. The outer wall of the missing gear 38 is meshed with a full gear 26. The full gear 26 is rotatably connected to the bottom of the cutting table 1 through a shaft and is fixedly connected to a bearing rod 28. The same ring spring 27 is fixedly connected to both sides of the bearing rod 28.

[0028] The end of the second shaft 39 is fixedly connected to a gear 40, and the outer wall of the gear 40 is meshed with a helical rack 41. The helical rack 41 is slidably connected to the cutting table 1, and a second spring 43 is fixedly connected between the helical rack 41 and the cutting table 1.

[0029] In this embodiment, before the bearing frame 8 rotates, the first shaft 32 drives the missing gear 38 to rotate through the transmission wheel 29 and the belt 30. When the missing gear 38 meshes with the full gear 26, it drives the bearing rod 28 to rotate, so that the bearing rod 28 no longer supports the other end of the bearing frame 8, which facilitates the subsequent cutting of the plate by the bearing frame 8.

[0030] The support frame 8 is provided with symmetrically distributed central sliding plates 9. The two central sliding plates 9 are slidably connected to the cutting table 1. The bottom of the central mounting frame 17 is fixedly connected to the unloading box 14. The middle of the unloading box 14 is fixedly connected to the partition 12. The partition 12 is flush with the edge of the support frame 8.

[0031] A door panel 3 is hinged to one side of the storage frame 2. A push block 4 is slidably connected to the door panel 3. A discharge baffle 7 is slidably connected to the side of the storage frame 2 away from the door panel 3. A threaded rod 18 is threadedly connected to the top of the discharge baffle 7. The threaded rod 18 is threadedly connected to the inside of the storage frame 2.

[0032] In this implementation scheme, electrical cabinet panels are stacked in the storage frame 2. The distance that the push block 4 moves on the door panel 3 is adjusted according to the thickness and length of the cabinet panels, so that after the door panel 3 is closed, the push block 4 presses the cabinet panels against the discharge baffle 7 to ensure their neatness. The threaded rod 18 is adjusted according to the thickness of the cabinet panels so that only one cabinet panel can slide out from the bottom of the discharge baffle 7. The distance between the two central sliding plates 9 is adjusted so that the distance between the two central sliding plates 9 is the same width as the cabinet panels.

[0033] The working principle and usage of this invention are explained in detail below: The electrical cabinet panels are stacked in the storage frame 2. The distance that the push block 4 moves on the door panel 3 is adjusted according to the thickness and length of the cabinet panels so that after the door panel 3 is closed, the push block 4 presses the cabinet panels against the discharge baffle 7 to ensure their neatness. The threaded rod 18 is adjusted according to the thickness of the cabinet panels so that only one cabinet panel can slide out from the bottom of the discharge baffle 7. The distance between the two central sliding plates 9 is adjusted so that the distance between the two central sliding plates 9 is equal to the width of the cabinet panels.

[0034] Subsequently, motor 34 starts, driving first gear 31 and first shaft 32 to rotate via second gear 33. This causes mounting rod 25 on first shaft 32 to slide along guide plate 23 via push rod 24. Through mounting plate 20, connecting plate 19, and push plate 5, the lowest cabinet panel is pushed out of storage frame 2. It automatically centers itself via two centering slide plates 9. Then, first slide block 13, carrying second slide block 15, slides along mounting rail 16. Second slide block 15, carrying plasma cutting mechanism 11, slides along first slide block 13. Plasma cutting mechanism 11 slides on second slide block 15, performing window cutting on the cabinet panel. After cutting, the mounting rod 25 rotates with the push rod 24 to below the inclined block 35. The push rod 24 abuts against the inclined block 35 and pushes the inclined block 35 upward, thereby driving the demolding rod 10 to rotate toward the support frame 8 through the gear 1 37. The demolding rod 10 separates the plate cut in the middle of the support frame 8. The cut plate falls to one side of the partition 12 in the material box 14. When the mounting rod 25 rotates to below the helical rack 41, it also pushes the helical rack 41 upward. Through the gear 2 40, it drives the second shaft 39 and the support frame 8 to rotate downward, dropping the electrical cabinet plate into the material box 14, which is the other side of the partition 12.

[0035] Before the bearing frame 8 rotates, the first shaft 32 drives the missing gear 38 to rotate through the transmission wheel 29 and belt 30. When the missing gear 38 meshes with the full gear 26, it drives the bearing rod 28 to rotate, so that the bearing rod 28 no longer supports the other end of the bearing frame 8, which makes it easier for the bearing frame 8 to cut the cut plate.

[0036] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
