Description

Technical Field

[0001] This invention belongs to the field of sheet metal cutting and processing technology, specifically relating to a sheet metal cutting and processing equipment for high and low voltage power distribution cabinets. Background Technology

[0002] Sheet metal work is a comprehensive cold processing technology for thin metal sheets, including shearing, punching, cutting, compounding, bending, welding, riveting, splicing, and forming. Sheet metal parts in high and low voltage distribution cabinets are one of the key components used to manufacture the housings of these power distribution equipment. These sheet metal parts not only provide physical support and protection for electrical components, but also serve as electrical isolation. Sheet metal parts for high and low voltage distribution cabinets need to be cut into specific shapes or holes to facilitate ventilation and heat dissipation. In existing technologies, sheet metal parts are generally transported to the underside of the cutting head via a conveyor belt, and then the transport stops. Through the design of hydraulic cylinders and linear guides, the extension degree of the hydraulic cylinders is preset by the control panel, and the hydraulic cylinders will automatically extend vertically downwards until the cutting blade inside the cutting head contacts the sheet metal parts on the conveyor belt. Then the control panel automatically turns on the switch of the linear guide, which allows the cutting head to move back and forth in a linear motion to cut the sheet metal parts. However, there are the following drawbacks: although the sheet metal parts are carried by the conveyor belt to the underside of the cutting blade for cutting, because the sheet metal parts are not fixed on the conveyor belt, the sheet metal parts will shift when the cutting blade cuts, resulting in inaccurate cutting results.

[0003] A Chinese patent document with publication number CN118513606A proposes a sheet metal cutting device that uses a drive component and a pressing component to clamp and fix the sheet metal part to solve the above problems. However, the drive component has the problem that the transmission process is complicated and it can only complete the single-sided trimming operation at one time, which cannot perform complex cutting processing on the sheet metal part.

[0004] Therefore, this invention proposes a sheet metal cutting and processing equipment for high and low voltage distribution cabinets, which solves the problem that the transmission process of the drive component in the existing sheet metal processing is complicated and can only complete the single-sided trimming operation at one time, making it impossible to perform complex processing on sheet metal parts. By adopting a composite cutting mold, complex cutting and processing of sheet metal parts for high and low voltage distribution cabinets can be performed with the cooperation of stamping equipment, and the edge folding process can be completed at the same time during the cutting process, thereby improving the efficiency of sheet metal processing. Summary of the Invention

[0012] Preferably, the sheet metal cutting table is symmetrically and rotatably mounted with side support wing plates on both sides, the rotating shaft of the side support wing plates is penetrated by limiting sleeves on both sides, and gears are fixedly mounted at both ends of the rotating shaft of the side support wing plates, and the side surfaces of the gears mesh with the side surfaces of the guide rack.

[0013] Preferably, a slide rod is symmetrically and obliquely fixedly installed at 45° on the inner side wall of the sheet metal cutting table, and a support frame is movably installed on the slide rod.

The telescopic push rod device pushes the positioning frame to press the edge of the sheet metal part before cutting, avoiding misalignment and improving processing accuracy. In addition, by adding L-shaped side support wing plates to both sides of the sheet metal cutting table, and using them in conjunction with the folding punch under the stamping mounting plate, the folding operation is completed at the same time as the sheet metal part is cut, improving the efficiency of sheet metal part processing. This solves the problem that the transmission process of the drive assembly in the existing sheet metal part processing process is complicated and can only complete the single-sided edge cutting operation at one time, which cannot perform complex processing of sheet metal parts.

[0036] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0037] Example 1

[0038] Please see Figures 1 to 17This invention provides a technical solution: a sheet metal cutting and processing equipment body 1, an electrical control box 11 fixedly installed on the upper side of one side of the body 1, a stamping device 4 fixedly installed at the top inside the body 1, telescopic push rod devices 5 symmetrically fixedly installed on both sides inside the body 1, a stamping and cutting assembly 3 arranged below the stamping device 4, and a cutting table assembly 2 arranged below the stamping and cutting assembly 3, the cutting table assembly 2 including a sheet metal cutting table 2. 1. The lower cutting mounting bracket 23 and the cutting shape plate 25 are cut. The stamping cutting assembly 3 includes a stamping mounting plate 31, an upper cutting mounting bracket 32, and a cutting blade 34. The sheet metal cutting table 21 is fixedly installed inside the middle of the sheet metal cutting processing equipment body 1. Limit sleeves 211 are symmetrically fixedly installed on the outer side of the sheet metal cutting table 21. The lower cutting mounting bracket 23 is fixedly installed above the inner surface of the sheet metal cutting table 21. The cutting shape plate 25 is snapped into the inside of the lower cutting mounting bracket 23. The two sides of the lower cutting mounting bracket 23 are symmetrical. A mounting guide post 231 is provided, and a repulsive magnetic ball 232 is movably installed inside the mounting guide post 231. Mounting holes 251, matching the mounting guide post 231, are provided on both sides of the cutting shape plate 25. The sheet metal cutting table 21 is fixedly installed inside the middle of the sheet metal cutting processing equipment body 1. Limit sleeves 211 are symmetrically fixedly installed on the outer side of the sheet metal cutting table 21. The lower cutting mounting bracket 23 is fixedly installed above the inner surface of the sheet metal cutting table 21. The cutting shape plate 25 is snapped onto the lower cutting mounting bracket 23. Inside, the cutting mounting bracket 23 has symmetrical mounting guide posts 231 on both sides. Mutually repulsive magnetic balls 232 are movably installed inside the mounting guide posts 231. The cutting shape plate 25 has mounting holes 251 on both sides that are compatible with the mounting guide posts 231. The cutting mounting bracket 23 has a fragment export frame 22 below it. The fragment export frame 22 is fixedly installed in the middle of the sheet metal cutting table 21. The sheet metal cutting table 21 and the sheet metal cutting processing equipment body 1 both have through slots that are compatible with the fragment export frame 22 in the middle.

[0039] In this embodiment, the cutting table assembly 2 and the stamping cutting assembly 3 form a complete cutting table. The cutting blade 34 and the cutting shape plate 25 are adapted to serve as a blade and blade table for special-shaped cutting of sheet metal parts for high and low voltage distribution cabinets. The upper cutting mounting bracket 32 ​​is located below the stamping mounting plate 31 and can be fixedly installed below the stamping mounting plate 31 with bolts. Similarly, the cutting shape plate 25 is fixedly installed above the sheet metal cutting table 21 with the lower cutting mounting bracket 23. The installation guide post 231 guides the installation of the cutting shape plate 25. The mounting hole 251 and the installation guide post 231 are positioned and pressed down on the cutting shape plate 25. At this time, the mutual repulsion magnetic balls 232 are squeezed. After installation, the mutual repulsion magnetic balls 232 are used to magnetically interact. The repulsion causes the small ball to be inserted into the mounting hole 251 to fix the cutting shape plate 25. The upper part of the stamping mounting plate 31 is fixed to the stamping equipment 4 with bolts. The operation of the stamping equipment 4 pushes the stamping mounting plate 31 down to make the cutting tool 34 penetrate the sheet metal on the cutting shape plate 25, and cut the sheet metal to form a specific shape or hole, which facilitates ventilation and heat dissipation of the high and low voltage distribution cabinet. The cutting tool 34 and the cutting shape plate 25 are detachable and easy to disassemble and replace. The telescopic push rod device 5 can push the positioning frame 24 to press the edge before the sheet metal is cut, avoid misalignment, and improve the processing accuracy. The limiting sleeve 211 set on the outside of the sheet metal cutting table 21 plays a guiding and positioning role for the guide rack 311 when the stamping mounting plate 31 moves down.

[0040] Example 2

[0041] Please see Figures 1 to 17 Based on Embodiment 1, in order to make sheet metal processing more convenient, this embodiment also proposes that a fragment collection box 12 is movably installed below the internal through groove of the sheet metal cutting and processing equipment body 1, an automatic conveying device 13 and an automatic output device 15 are respectively arranged on both sides of the sheet metal cutting and processing equipment body 1, the cutting and processing table assembly 2 is arranged between the automatic conveying device 13 and the automatic output device 15, a sensing device 14 is arranged above the end of the automatic conveying device 13 near the cutting and processing table assembly 2, the sensing device 14 is fixedly installed on the side wall of the sheet metal cutting and processing equipment body 1, and a sensor is arranged below the sensing device 14 to monitor the edge position of the sheet metal sheet;

[0042] In this embodiment, the stamping mounting plate 31 presses down to cause the cutting blade 34 to penetrate the sheet metal on the cutting shape plate 25, cutting the sheet metal to form a specific shape or hole. The generated fragments are collected in the fragment collection box 12 through the fragment export box 22. The fragment collection box 12 can be removed for cleaning. The automatic conveying device 13 and the automatic output device 15 both play the role of automatic feeding and unloading. The automatic conveying device 13 conveys the sheet metal sheet above the cutting shape plate 25. The sensing device 14 uses a sensor to locate the edge position of the sheet metal sheet. When the sheet metal sheet reaches the designated position, the automatic conveying device 13 stops. Then, the sheet metal sheet is cut and processed into sheet metal parts for high and low voltage distribution cabinets and output through the automatic output device 15, making sheet metal processing more convenient and improving processing efficiency.

[0043] Example 3

[0044] Please see Figures 1 to 17 Based on Embodiment 2, in order to keep the sheet metal parts stable during processing, this embodiment also proposes that positioning frames 24 are symmetrically slidably installed on both sides of the upper surface of the cutting mounting frame 23. The outer surfaces of the two sets of positioning frames 24 are respectively fixedly connected to the output end of the telescopic push rod device 5 by bolts. A pressing strip 241 is slidably installed on the inner side of the positioning frame 24. The inner side of the pressing strip 241 is set as a bevel. A movable extrusion core plate 242 is fixedly installed on the upper surface of the pressing strip 241. A sliding groove adapted to the movable extrusion core plate 242 is provided on the upper inner wall of the positioning frame 24. The movable extrusion core plate 242 is composed of a semi-circular pad and a trapezoidal wedge. A pressing spring 243 is fixedly installed on the inner side wall of the positioning frame 24. The lower end of the pressing spring 243 is fixedly connected to one side of the upper surface of the pressing strip 241.

[0045] In this embodiment, the telescopic push rod device 5 pushes the positioning frame 24 to move inward. The pressing strip 241 presses the sheet metal sheet on the cutting shape plate 25 under the action of the pressing spring 243. The pressing strip 241 is set as an inclined plate, which can simultaneously squeeze both sides of the sheet metal sheet during the movement to keep it in a centered position. It is also easier to generate inward cutting pressure to stably clamp and fix both sides of the sheet metal sheet. The movable extrusion core plate 242 moves upward and protrudes when the pressing strip 241 presses the sheet metal sheet on the cutting shape plate 25. The rear stamping mounting plate 31 presses down so that the cutting knife 34 can press the movable extrusion core plate 242 when cutting. During the cutting process, the pressing strip 241 is stably fixed to both sides of the sheet metal to avoid movement error. The special shape of the movable extrusion core plate 242 can evenly distribute the pressure and maintain the pressing strip 241 to generate stable pressure on the top of the sheet metal part.

[0046] Example 4

[0047] Please see Figures 1 to 17Based on Embodiment 3, in order to allow for folding of the sheet metal parts during the cutting process, this embodiment further proposes that side support wing plates 26 are symmetrically and rotatably mounted on both sides of the sheet metal cutting table 21. Limiting sleeves 211 pass through both sides of the rotating shaft of the side support wing plates 26. Gears 261 are fixedly mounted at both ends of the rotating shaft of the side support wing plates 26. The side surfaces of the gears 261 mesh with the side surfaces of the guide racks 311. Slide rods 212 are symmetrically and obliquely fixedly mounted at 45° on the inner side wall of the sheet metal cutting table 21. A support frame 213 is movably mounted on the slide rod 212. One end of the support frame 213 is movably connected to the inner surface of the side support wing plates 26. A spring 214 is sleeved on the outside of the slide rod 212. One end of the spring 214 is connected to the side surface of the support frame 213. The inner wall of the sheet metal cutting table 21 is symmetrically and obliquely fixedly installed with a slide rod 212 at 45°. A support frame 213 is movably installed on the slide rod 212. One end of the support frame 213 is movably connected to the inner surface of the side support wing plate 26. A spring 214 is sleeved on the outside of the slide rod 212. One end of the spring 214 is in contact with the side surface of the support frame 213. A guard plate 321 is provided below the cutting blade 34. Connecting metal gaskets 3211 are symmetrically fixedly installed on both sides of the upper surface of the guard plate 321. A pad mounting slide 3212 that matches the connecting metal gasket 3211 is symmetrically fixedly installed on both sides of the lower surface of the upper cutting mounting frame 32. The guard plate 321 is slidably installed below the pad mounting slide 3212 through the connecting metal gasket 3211.

[0048] In this embodiment, the side support wing plate 26 is L-shaped and initially holds in an upturned position, with its upper end flush with the cutting shape plate 25, providing auxiliary support to both sides of the sheet metal plate. When the stamping mounting plate 31 is pressed down, the guide rack 311 moves down, driving the gear 261 to rotate, causing the side support wing plate 26 to flip downwards. When the cutting tool 34 completes the through-cutting of the cutting shape plate 25, the folding punches 33 installed on both sides below the stamping mounting plate 31 cooperate with the side support wing plate 26 to complete the folding of the sheet metal plate. This avoids the problems of inconvenient cutting caused by bending before cutting in the traditional processing mode and deformation of the cutting groove caused by cutting before bending. It improves processing efficiency by performing the process simultaneously. The support frame 213 provides auxiliary support to the side support wing plate 26. The support frame 213 slides on the slide rod 212 in conjunction with the flipping of the side support wing plate 26. After the cutting is completed, the stamping mounting plate 31 rises, and the spring 214 pushes the support frame 213 to reset, which in turn pulls the side support wing plate 26 to flip and reset. This allows the cut sheet metal parts to be pushed out for easy unloading. In addition, the guard plate 321 is installed below the cutting blade 34 to protect the edge of the cutting blade 34. The guard plate 3211 is installed on the pad mounting slide 3212 through the connecting metal shim 3211. When the cutting blade 34 penetrates the cutting shape plate 25 for cutting, the connecting metal shim 3211 rises and is compressed and expanded. The pad mounting slide 3212 squeezes it to keep the guard plate 321 at a certain height and avoids overpressure.

[0049] Example 5

[0050] Please see Figures 1 to 17 Based on Embodiment 4, in order to make the cutting of the cutting blade 34 more stable, this embodiment also proposes that the outer surface of the upper cutting mounting bracket 32 ​​is fixedly installed with a side arc-shaped protective pressure plate 322 by bolts, and a spring sleeve 341 is movably installed inside the cutting blade 34. The cutting blade 34 is provided with a threaded mounting hole that matches the spring sleeve 341, and a spring push rod is movably installed inside the spring sleeve 341.

[0051] In this embodiment, when the cutting tool 34 is cutting, the side arc-shaped protective pressure plate 322 is installed on the outside to provide a certain protective function. At the same time, during the cutting process, the downward deformation presses against the movable extrusion core plate 242 to ensure the stable fixation of the pressure strip 241 on both sides of the sheet metal. The spring sleeve 341 is rotatably installed on the inside of the cutting tool 34. When the cutting tool 34 penetrates and cuts, the spring push rod inside can push out the fragments from the cutting opening, which facilitates the discharge of the fragments.

[0052] Example 6

[0053] Please see Figures 1 to 17Based on Embodiment 5, this embodiment also proposes a method for using sheet metal cutting and processing equipment for high and low voltage distribution cabinets, including the following steps:

[0054] Step 1: Feeding the sheet metal sheet. The automatic conveying equipment 13 conveys the sheet metal sheet to the top of the cutting shape board 25. The sensing equipment 14 uses sensors to position the edge of the sheet metal sheet. After the sheet metal sheet reaches the designated position, the automatic conveying equipment 13 stops. The telescopic push rod equipment 5 pushes the positioning frame 24 to press the edge before the sheet metal part is cut.

[0055] Step 2: Cutting process. The stamping equipment 4 pushes the stamping mounting plate 31 down to make the cutting tool 34 penetrate the sheet metal on the cutting shape plate 25 and cut the sheet metal to form a specific shape or hole.

[0056] Step 3, unloading: The stamping equipment 4 is raised to lift the stamping mounting plate 31. The spring 214 pushes the support frame 213 to reset, and the side support wing plate 26 is pulled and flipped to reset. The cut sheet metal parts can then be output through the automatic output device 15.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
