Description

Technical Field

[0001] This invention relates to the field of box panel cutting and processing technology, and in particular to a component cutting device for the production and processing of electricity metering boxes. Background Technology

[0002] Plasma cutting is a mainstream process for sheet metal processing of power distribution cabinets and power metering boxes. It utilizes a plasma arc at tens of thousands of degrees Celsius to melt metal sheets, combined with a high-speed airflow to remove molten slag. This allows for the rapid cutting of irregularly shaped parts such as cabinet frames, observation holes, and knockout holes, and is widely used in the batch processing of 8-20mm thick carbon steel and stainless steel metering boxes. However, the plasma cutting process simultaneously generates harmful fumes such as high-temperature molten slag, metal dust, ozone, and nitrogen oxides. Furthermore, hard oxide burrs easily form along the lower edge of the cut. Without an integrated cleaning, cooling, and dust removal system, post-processing labor will be significantly increased, the workshop environment will be polluted, and the quality of the box's powder coating for rust prevention and assembly will be affected.

[0003] An investigation revealed that a Chinese invention patent discloses a plasma cutting device for processing power distribution cabinets (publication number: CN121339625A), which includes a machine tool, a cutting mechanism, and a fixing mechanism. The cutting mechanism is located on the top of the machine tool, and the fixing mechanism is located at the bottom of the cutting mechanism. The cutting mechanism includes an integrated end head, which is located on the top of the machine tool, and a top protective shell is installed at the bottom of the integrated end head.

[0004] While the aforementioned patent improves the flatness of sheet metal cutting by using a multi-angle deflection cutting nozzle adapted to sheet metal with concave and convex shapes and combining it with an elastic pressure shaft mechanism on the upper surface to suppress thermal deformation during thin sheet cutting, this device only solves the problems of nozzle angle adjustment and deformation prevention on the top surface of thin sheets. It lacks integrated solutions for simultaneous scraping of slag at the bottom of the sheet metal, segmented air-cooling buffer cooling, mechanical linkage lateral reciprocating grinding, gravity-graded integrated slag and smoke collection, and follow-up support to prevent falling. It cannot achieve continuous automated operation of cutting, scraping, cooling, grinding, and dust removal. The processing of thick-specification power metering boxes suffers from multiple pain points such as low efficiency, high material consumption, failure to meet environmental standards, difficulty in cleaning burrs at the cut, and equipment interference. Therefore, there is an urgent need for a new integrated bottom-following plasma cutting auxiliary device to solve the above defects.

[0005] Therefore, this application provides a component cutting device for the production and processing of electricity metering boxes to meet the requirements. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a cutting device for parts of electricity metering boxes, so as to solve the problems of difficult slag removal, inefficient grinding, and difficulty in collecting smoke and dust and motion interference caused by the bottom mechanism.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A component cutting device for the production and processing of electricity metering boxes includes a frame and a plasma cutting device. A mounting frame is provided below the plasma cutting device. A first slide rail is mounted on the frame, and two second slide rails are installed between the first slide rails. The mounting frame and the plasma cutting device are respectively mounted on the two second slide rails. A mounting base is mounted on the mounting frame, and a hopper is installed inside the mounting base, with a scraper plate mounted on the hopper. An air supply assembly is provided inside the mounting base for air-cooling the plate and collecting dust. The air supply assembly includes a dust collection hopper and a blower pipe. A grinding mechanism is mounted on the dust collection hopper for repeatedly grinding burrs at the bottom of the cutting line. The grinding mechanism includes a grinding roller, a drive wheel, and a connecting rod.

[0008] Optionally, the blowing pipe is installed close to the hopper, the ash collection hopper is fixedly sleeved on the outside of the blowing pipe and the hopper, and fixedly installed in the mounting base, the bottom of the ash collection hopper is rotatably sealed with a first annular pipe, and the bottom of the blowing pipe is rotatably sealed with a second annular pipe.

[0009] Optionally, the mounting base is sequentially equipped with an air-cooling device, a first collection box, and a second collection box. The bottom of the hopper is sealed to the first collection box, and the second annular pipe is sealed to the air-cooling device.

[0010] Optionally, a suction fan is sealed to the top of the second collection box, and the air inlet of the suction fan is sealed to the first collection box and the first annular pipe respectively.

[0011] Optionally, a first collection box and a second collection box are respectively installed on the first collection box and the second collection box. A baffle is fixedly installed inside the first collection box. An installation platform is fixedly connected to the installation frame, and the installation seat is rotatably connected to the installation platform.

[0012] Optionally, a mounting plate is slidably connected to the top of the hopper, the scraper is mounted on the mounting plate, a plurality of round rods are fixedly connected to the mounting plate, and the bottom of the round rods is slidably inserted into the top of the hopper. A spring is sleeved on the round rod, and the two ends of the spring are fixedly connected to the mounting plate and the hopper, respectively.

[0013] Optionally, the mounting base is movably connected with multiple balls, and the mounting base is symmetrically fixed with protrusions, and the protrusions are rotatably connected with a spline shaft, and two rollers are coaxially fixed on the spline shaft.

[0014] Optionally, a bracket is fixedly connected to the ash collection hopper, and a bevel gear set is provided between the spline shaft and the bracket. The bevel gear set includes two meshing bevel gears, one of which is coaxially fixed with the spline shaft, and the other bevel gear is rotatably connected to the bracket and connected to the drive wheel through a pulley set.

[0015] Optionally, a protective shell is fixedly installed on the bracket, the drive wheel is rotatably connected to the bracket, a movable frame is slidably connected to the bracket, an mounting block is fixedly connected to the movable frame, the grinding roller is rotatably connected between the movable frame and the mounting block, and the connecting rod is rotatably connected between the drive wheel and the movable frame.

[0016] Optionally, the mounting block is rotatably connected to an end face gear and a spur gear, with the end face gear meshing with the spur gear. The spur gear is fixed coaxially with the grinding roller, and the spline shaft slides coaxially with the end face gear.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, the scraper moves synchronously along the cutting trajectory with the plasma cutting equipment, which can scrape off the semi-solidified slag adhering to the lower surface of the plate immediately after cutting. This reduces the cleaning difficulty caused by the increased adhesion strength of the slag after solidification. At the same time, the air-cooled airflow blown out by the air supply component below can quickly cool down the high-temperature plate after cutting, reducing the degree of thermal deformation of the plate. The generated slag falls directly into the hopper for initial collection after being scraped off. The fumes generated during the cutting process are sucked into the ash collection hopper by the air supply airflow and the suction fan, and then sent to the second collection box for collection. This achieves classified collection and treatment of slag and fumes, avoiding the spread of harmful fumes and pollution of the workshop environment.

[0018] By setting up a grinding mechanism that can move synchronously with the scraper, the drive wheel drives the connecting rod to push the movable frame to slide back and forth, driving the grinding roller to grind the hard oxide burrs generated at the lower edge of the cut along the cutting line. This eliminates the need for subsequent manual grinding, reducing post-processing labor costs and improving the overall quality of the cut. Through the spline shaft in conjunction with the bevel gear set and pulley set, power can be obtained by using the friction generated by the plate traveling in contact with the roller. This eliminates the need for an additional power source to drive the grinding roller to rotate and grind, and can also drive the drive wheel to move the grinding roller back and forth, improving energy utilization and reducing the overall energy consumption of the device.

[0019] The first and second collection boxes collect the scraped slag and the sucked-in dust, respectively. With the help of the baffle in the first collection box, gravity classification and feeding are achieved. Large slag particles fall directly into the first collection box, while small dust particles are sucked into the second collection box for collection. This improves the convenience of waste collection and classification. The mounting base is rotatably connected to the mounting platform and can adaptively deflect along the cutting trajectory, ensuring that the grinding mechanism is always positioned behind the plasma cutting equipment. For the cut kerf, the ball bearings provide follow-up support to prevent the plate cutting part from sagging and deforming due to suspension, ensuring cutting accuracy and avoiding interference between the device and the plate movement.

[0020] By integrating cutting and slag scraping, air cooling, burr grinding, and slag and fume collection into the same accompanying auxiliary mechanism, which moves synchronously with the plasma cutting equipment, continuous automated operation of cutting, cleaning, grinding, and dust removal can be achieved. This effectively solves the problems of difficult slag removal, low burr grinding efficiency, and harmful fume diffusion in the existing sheet metal cutting and processing of power metering boxes, and is suitable for batch processing.

Detailed Implementation

[0023] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0024] like Figures 1 to 9 As shown, an embodiment of the present invention provides a component cutting device for the production and processing of electricity metering boxes, including a frame 1 and a plasma cutting device 4. A mounting frame 5 is provided below the plasma cutting device 4. A first slide rail 2 is installed on the frame 1, and two second slide rails 3 are installed between the first slide rails 2. The mounting frame 5 and the plasma cutting device 4 are respectively installed on the two second slide rails 3. A mounting base 6 is installed on the mounting frame 5. A hopper 16 is installed in the mounting base 6, and a scraper 17 is installed on the hopper 16. An air supply component is provided in the mounting base 6. The air supply component is used for air cooling of the plate and collecting dust. The air supply component includes a dust collection hopper 21 and a blower duct 22. A grinding mechanism is installed on the dust collection hopper 21. The grinding mechanism is used for repeatedly grinding the burrs at the bottom of the cutting line. The grinding mechanism includes a grinding roller 20, a drive wheel 31, and a connecting rod 32.

[0025] The first slide rail 2 is the horizontal movement track for the whole machine. The two independent second slide rails 3 respectively support the plasma cutting equipment 4 and the bottom mounting frame 5, realizing the synchronous linkage of the cutting unit, slag scraping, cooling and grinding unit. There is no positional deviation during the movement process, ensuring that slag scraping, air cooling and grinding are always accurately aligned with the cutting seam. This solves the problem of motion interference between the bottom cleaning mechanism and the plate support from the root. It should be noted that there are adjustable telescopic components, such as hydraulic rods, between the plasma cutting equipment 4 and the mounting frame 5 and the two second slide rails 3. These components can drive the plasma cutting equipment 4 and the mounting frame 5 to adaptively fit the plate. The plasma cutting equipment 4, the first slide rail 2, the second slide rail 3 and the telescopic components are all existing mature devices in plasma cutting technology, and will not be elaborated on here.

[0026] like Figures 3 to 6As shown, the blower pipe 22 is installed adjacent to the hopper 16. The ash collection hopper 21 is fixedly sleeved on the outside of the blower pipe 22 and the hopper 16, and fixedly installed in the mounting base 6. The bottom of the ash collection hopper 21 is rotatably sealed with the first annular pipe 26, and the bottom of the blower pipe 22 is rotatably sealed with the second annular pipe 27. The air-cooling device 11, the first collection box 9, and the second collection box 12 are sequentially installed on the mounting base 6. The bottom of the hopper 16 is sealed to the first collection box 9, and the second annular pipe 27 is sealed to the air-cooling device 11. The first annular pipe 26 and the second annular pipe 27 are rotatably sealed. The sealed structure ensures that the air duct remains airtight during the deflection and adjustment of the mounting base 6, guaranteeing the continuous and stable operation of air cooling and negative pressure dust removal. The top of the second collection box 12 is sealed with a suction fan 14, and the air inlet of the suction fan 14 is sealed with the first collection box 9 and the first annular pipe 26 respectively. The first collection box 9 and the second collection box 12 are respectively equipped with a first collection box 10 and a second collection box 13. A baffle 15 is fixedly installed inside the first collection box 9, and a mounting platform 7 is fixedly connected to the mounting frame 5. The mounting base 6 is rotatably connected to the mounting platform 7.

[0027] Baffle 15 forms a gravity settling chamber inside the first collection box 9, realizing the physical classification and diversion of molten slag and dust. High-temperature large pieces of steel slag settle to the first collection box 10 by their own weight, and will not be sucked into the rear air duct by the negative pressure airflow, thus avoiding the high-temperature waste slag from puncturing and burning the dust removal filter material. The blower 22 directionally discharges air, which, together with the suction fan 14, forms a directional airflow field under negative pressure. This can quickly cool the high-temperature plate and collect all the cutting dust into the dust collection hopper 21, preventing smoke from overflowing and improving the environmental protection effect of the workshop. The rotating seal first annular pipe 26 and second annular pipe 27 are adapted to the mounting base 6 for cutting. The profile adaptive deflection prevents air leakage due to bending of the duct. The air volume for both cooling and suction remains stable throughout. It should be noted that the installation positions of the air-cooling device 11 and the suction fan 14 can be selected according to their actual dimensions. The figure shows an example of installation on the mounting bracket 5. If the air-cooling device 11 and the suction fan 14 are large, they can be installed on the frame 1. The connection between them can be sealed with a hose of sufficient length, which does not affect the movement and deflection of the mounting base 6, while also ensuring continuous air supply. Both the air-cooling device 11 and the suction fan 14 are existing mature technologies in this field and will not be elaborated on further here.

[0028] like Figure 7As shown, a mounting plate 23 is slidably connected to the top of the hopper 16, and a scraper plate 17 is mounted on the mounting plate 23. Multiple round rods 28 are fixedly connected to the mounting plate 23, with the bottom of each rod 28 slidably inserted into the top of the hopper 16. Springs 29 are fitted onto each rod 28, and both ends of the springs 29 are fixedly connected to the mounting plate 23 and the hopper 16, respectively. The multiple round rods 28 provide vertical guidance and limit to the mounting plate 23, while the springs 29 continuously push the scraper plate 17 upwards to conform to the bottom surface of the plate, forming a floating adaptive structure. (The last sentence appears to be incomplete and possibly refers to a partial view of the plate.) When there is warping or tolerance in the thickness of the sheet material, the scraper 17 can automatically move downwards, preventing it from scraping the sheet material and causing scratches on the surface. At the same time, it always stays close to the lower edge of the cut and removes the slag before it is completely solidified, which greatly reduces the adhesion strength of slag agglomerates and reduces the subsequent grinding load. The scraper 17, the hopper 16, and the components near the plasma cutting equipment 4 are all made of high-temperature resistant materials to ensure that the device below will not be damaged by high temperature during the cutting of the sheet material. The scraper 17 and the mounting plate 23 can be detached for easy replacement later.

[0029] like Figure 8 and Figure 9 As shown, multiple ball bearings 8 are movably connected to the mounting base 6. Protrusions are symmetrically fixed to the mounting base 6, and a splined shaft 33 is rotatably connected between the protrusions. Two rollers 25 are coaxially fixed to the splined shaft 33. A bracket 18 is fixedly connected to the ash hopper 21. A bevel gear set 36 is provided between the splined shaft 33 and the bracket 18. The bevel gear set 36 includes two meshing bevel gears. One bevel gear is coaxially fixed to the splined shaft 33, and the other bevel gear is rotatably connected to the bracket 18 and connected to the drive wheel 31 via a pulley set 37. A protective shell 24 is fixedly installed on the bracket 18 to isolate the high temperature of cutting and splashed slag, protecting the material. The internal bevel gear group 36, pulley group 37, drive wheel 31 and other transmission components extend the service life of the mechanism. The drive wheel 31 is rotatably connected to the bracket 18. The movable frame 19 is slidably connected to the bracket 18. The mounting block 30 is fixedly connected to the movable frame 19. The grinding roller 20 is rotatably connected between the movable frame 19 and the mounting block 30. The connecting rod 32 is rotatably connected between the drive wheel 31 and the movable frame 19. The end face gear 34 and the spur gear 35 are rotatably connected inside the mounting block 30. The end face gear 34 and the spur gear 35 mesh. The spur gear 35 is coaxially fixed with the grinding roller 20. The spline shaft 33 is coaxially sliding with the end face gear 34.

[0030] The ball bearing 8 continuously supports the cutting point of the plate, solving the problem of the middle part being suspended and deformed due to only the edge support of the large plate, and ensuring the cutting dimension accuracy. The roller 25 drives the entire transmission mechanism by walking friction, without the need for an additional motor or cylinder as the grinding power, simplifying the overall power configuration of the machine and reducing equipment energy consumption and manufacturing costs. The bevel gear group 36, the pulley group 37, the end face gear 34, and the spur gear 35 form a two-stage transmission, which synchronously outputs the rotational power of the grinding roller 20 and the lateral reciprocating sliding force of the movable frame 19, realizing the cross reciprocating compound grinding of rotational grinding and vertical cutting line, thoroughly removing the oxide burrs distributed laterally along the lower edge of the cut. The spline shaft 33 and the end face gear 34 slide in fit, adapting to the continuous and stable power transmission during the repeated movement of the grinding roller 20, without transmission disengagement failure.

[0031] The working principle of the technical solution provided by this invention is as follows: During operation, the first slide rail 2 on the frame 1 drives the two sets of second slide rails 3 to move synchronously. The plasma cutting equipment 4 and the supporting mounting frame 5 below are respectively mounted on the two second slide rails 3. The two always keep in sync, so that the entire bottom mechanism of slag scraping, air cooling, grinding and dust collection always follows the plasma cutting torch closely and moves synchronously along the cutting trajectory.

[0032] In addition, the plate is placed on the workbench and supported only by the four edges. After the cutting is started, the plasma cutting equipment 4 completes the arc cutting along the preset contour of the plate. The molten steel slag generated by the cutting adheres downward to the lower edge of the plate cut under the action of the plasma gas flow. The scraper plate 17 moves closely to the bottom surface of the plate and removes large pieces of molten slag directly before the slag has completely cooled and solidified. The scraper plate 17 is floatingly assembled on the top of the hopper 16 through the mounting plate 23, the round rod 28 and the spring 29. The spring 29 continuously provides an upward clamping force to ensure that the scraper plate 17 always adheres to the bottom surface of the plate. When the plate warps slightly, it can automatically retract to avoid scratching or jamming the plate.

[0033] In addition, the large chunks of hot molten slag that are blown off fall vertically into the hopper 16 and eventually into the first collection box 9. The first collection box 9 is equipped with baffles 15 to create a gravity settling zone, allowing the large solid slag chunks to settle directly into the first collection box 10 for separate collection, achieving pre-separation of the slag and preventing high-temperature waste slag from entering the rear dust removal duct. Simultaneously with cutting, the air-cooling equipment 11 is activated, sending cold air through the second annular pipe 27 into the blowing pipe 22. The blowing pipe 22 blows low-temperature air laterally towards the cut, rapidly and forcibly cooling the newly cut high-temperature plate, shortening the plate's cooling time. To avoid the direct baking of the grinding mechanism by high temperature, which would cause the consumables to age and be damaged, the suction fan 14 continuously generates negative pressure. The air intake end of the suction fan 14 is connected to the first annular pipe 26 at the bottom of the first collection box 9 and the ash hopper 21. Under the action of negative pressure, fine dust and cooling hot air flow into the ash hopper 21 and are sent to the second collection box 12 through the pipeline. Fine dust is uniformly deposited inside the second collection box 13, realizing the graded and separate collection of slag and dust, preventing high temperature large slag from clogging and burning the dust removal filter material, and avoiding the unorganized diffusion of dust and pollution of the workshop.

[0034] In addition, the mounting base 6 is rotated and assembled on the mounting platform 7, and the bottom ball bearings 8 follow the bottom surface of the plate to support it. Since there is a center of gravity offset and a certain eccentricity between the mounting base 6 and the mounting platform 7, the mounting base 6 can rotate adaptively when the plasma cutting equipment 4 turns, ensuring that the grinding roller 20 and the air blowing pipe 22 are always behind the plasma cutting equipment 4 in the direction of travel, so as to cool and grind the cut kerf. The ball bearings 8 lift the cutting point of the plate in real time, solving the problem of the large-size plate being suspended and deformed in the middle, while avoiding interference between the bottom motion mechanism and the plate support structure.

[0035] In addition, during the movement of the equipment, the rollers 25 on both sides of the mounting base 6 continuously rub against the lower surface of the plate, and the spline shaft 33 rotates synchronously by the friction of the whole machine. The spline shaft 33 transmits the rotational power to the drive wheel 31 through the bevel gear group 36 and the pulley group 37. The drive wheel 31 and the connecting rod 32 form a crank-slider mechanism, which pulls the movable frame 19 on the bracket 18 to slide back and forth in a direction perpendicular to the cutting line, driving the grinding roller 20 to move laterally and crosswise, performing multiple cross-friction cutting on the burrs at the lower edge of the cut. At the same time, the spline shaft 33 and the end face gear 34 are synchronously transmitted through spline sliding cooperation. The end face gear 34 meshes with the spur gear 35 to drive the grinding. Roller 20 rotates on its own, and the self-rotating grinding combined with the transverse reciprocating sliding motion forms a compound grinding motion, which can remove the oxide burrs and small slags distributed under the cut to the maximum extent. The entire device relies on the slide rail to realize the synchronous linkage between the cutting unit and the bottom cleaning unit, and sequentially completes the fully automated operation of synchronous slag scraping, air cooling, dust extraction, mechanical linkage reciprocating grinding, and slag and smoke classification collection. The plate can be cut and the bottom burrs can be cleaned in a single pass without the need to transfer it to an independent grinding station, which greatly improves the sheet metal processing efficiency of the power metering box and improves the workshop processing environment. After processing, the first collection box 10 and the second collection box 13 can be directly pulled out to clean the steel slag and dust respectively.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
