Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting, and in particular relates to laser cutting equipment for processing and producing switch cabinets. Background Art

[0002] Switchgear is a key device used in power systems to distribute, control, protect, and monitor electrical energy. In order to better install the structure on it, laser cutting is usually used to fit the slots of the assembly parts. Laser cutting technology has the characteristics of high precision, high efficiency, and non-contact processing. It mainly uses a high-density laser beam to locally heat the material to melt or vaporize it, and blows away the slag with auxiliary gas. It is widely used in the processing of metal workpieces and plates. However, during cutting, the cross-section of the cutting gap may be uneven and inclined due to various reasons such as mismatch between laser power and speed, incomplete blowing away of slag, or thick workpieces. This uneven cross-section will make it impossible to accurately connect the workpieces, and tiny cracks will easily appear on the edges. Electrical components need to be arranged and installed very precisely in the switch cabinet, otherwise there will be power safety problems. Under dynamic loads, metal fatigue will be accelerated, leading to fracture. In existing technical solutions, the edges of metal workpieces are generally polished manually using an angle grinder, but this will consume a lot of labor costs, and the heat caused by laser cutting cannot evaporate quickly, and the temperature of the workpiece surface cannot be reduced to room temperature. In order to avoid burns, workers need to wait for a while before they can polish, which will undoubtedly consume some time costs. Therefore, it is necessary to provide a laser cutting equipment for switch cabinet processing and production. Summary of the Invention

[0003] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a laser cutting equipment for switch cabinet processing and production, which solves the problem that the cross-section of the cutting gap is uneven due to various reasons such as mismatch between laser power and speed, slag not being completely blown away or thick workpiece, and parts cannot be accurately installed inside the switch cabinet, which requires a lot of time and labor costs to repair.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a laser cutting device for processing and producing a switch cabinet, comprising a laser cutting device and a conveying mechanism, wherein a workpiece is placed on the conveying mechanism, and further comprising: a base provided at the bottom of the conveying mechanism; A grinding assembly mounted on top of the base; A space for grinding components is reserved in the middle of the conveying mechanism, and a set of rollers are provided on both sides of the top of the conveying mechanism; The grinding assembly includes a bearing plate rotatably mounted on the top of the base, a motor is fixedly mounted on the top of the base, a protective box is fixedly mounted on the top of the base, the bottom of the protective box is hinged to the protective box through a telescopic plate, and the top of the base is connected to the protective box through a hydraulic rod. The internal bearing of the protective box is equipped with a gear 1 and a gear 2 that mesh with each other. The gear 1 is connected to the output shaft of the motor through a transmission belt. The gear 2 is connected to a sanding roller through a transmission belt. The sanding roller is rotatably installed inside the protective box and the sanding part is located at the top of the protective box. A dustproof box is fixedly installed at the bottom of the protective box, the bottom of the dustproof box is connected to an inert gas tank, the top of the dustproof box is connected to a storage box through a rubber tube, and the top of the storage box is connected to a group of metal tubes in a circumferential array, which surround the sanding roller.

[0005] Preferably, the telescopic plate includes a metal sheet, which is arranged at the hinge of the telescopic plate and is respectively connected to the protective box and the protection box. A group of limit rods are respectively mounted on bearings at both ends of the telescopic plate, and each group of limit rods has two limit rods. The transmission belt is wrapped around each group of limit rods in an "S" shape.

[0006] Preferably, two rollers 1 are symmetrically arranged inside the telescopic plate, and the side of the telescopic plate is elastically connected to roller 2 through an elastic component. The roller 2 is slidably arranged on the side of the telescopic plate, and the transmission belt is guided by roller 1 and wound onto roller 2.

[0007] Preferably, a fan connected to gear 2 is installed inside the dustproof box, an air inlet is opened at the bottom of the dustproof box, the air inlet is closed by a metal filter, a hydraulic rod 3 is provided on the top of the base, and the inert gas tank is placed on the top of the hydraulic rod 3.

[0008] Preferably, the hydraulic rod 1 is slidably mounted on the top of the base, the top of the base is fixedly mounted with the hydraulic rod 2, and the movable end of the hydraulic rod 2 is fixedly connected to the bottom of the hydraulic rod 1.

[0009] Preferably, a clamping assembly is provided on both sides of the top of the base and the conveying mechanism; The clamping assembly includes a group of positioning plates 1 fixedly mounted on the top of the base, positioning plates 2 are slidably mounted on the positioning plates 1, and a lifting plate is commonly mounted on the bottom of each positioning plate 2. A hydraulic rod 5 is mounted on the top of the base, and the top of the hydraulic rod 5 is fixedly connected to the lifting plate.

[0010] Preferably, the travel track of the workpiece is located between the first positioning plate and the second positioning plate, and the maximum height to which the hydraulic rod five lifts the second positioning plate through the lifting plate is higher than the top of the conveying mechanism.

[0011] Preferably, a speed limiting component is provided on the top of the base; The speed limiting assembly includes a support tube fixedly mounted on the top of the base, and a group of arc-shaped spring telescopic rods are movably clamped on the inner wall of the support tube. Each of the arc-shaped spring telescopic rods is spirally distributed inside the support tube, and one end of the top arc-shaped spring telescopic rod is fixedly mounted on the base, and a hydraulic rod four is provided on the support tube at the other end of the arc-shaped spring telescopic rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a polishing assembly and other structures. The gas in the inert gas tank enters the storage box through the dustproof box and the rubber tube, and is finally ejected through several metal tubes. The temperature around the workpiece gap drops rapidly, reducing the damage to the sanding roller caused by high temperature. The sanding roller rotates, and the hydraulic rod drives the protective box to rise. According to the inertia generated by the rotation of the motor-driven gear one, the gear two guides the rotation of the protective box through resistance to prevent the sanding roller from moving and overlapping with the laser, causing the laser to damage the sanding roller. Finally, the sanding roller gradually polishes the cutting gap to make the cross-section of the cutting gap complete, and facilitates subsequent secondary processing and installation work. This makes the device work without too much manual intervention, and the sanding roller follows behind the moving trajectory of the laser, so it does not cause too much impact on the cutting work.

[0013] The present invention is provided with a grinding component and other structures. As long as the position of the sanding roller changes, the transmission belt will be pulled. Although it can work normally, frequent pulling will force the circumference of the transmission belt to increase and it will be unable to return to its original state. At this time, the transmission efficiency of the transmission belt will be reduced, and the loose state will also cause abnormal noises. When the sanding roller is grinding, slippage may occur between it and the transmission belt, but the elastic component always supports roller two. When the position of the sanding roller changes, the position of roller two can be changed in real time, so that the transmission belt can be continuously tightened, so that the transmission belt is always in the best transmission state to avoid the above situation.

[0014] The present invention cooperates with structures such as a grinding assembly and a speed limiting assembly. During the rotation of the supporting plate, it will also compress the arc spring telescopic rod. The elastic force therein will force the supporting plate to rotate slower, thereby preventing the laser from irradiating the grinding assembly and causing damage to it. When the top arc spring telescopic rod cannot be compressed, the corresponding hydraulic rod retracts, and the end of the upper arc spring telescopic rod pushes the end of the adjacent arc spring telescopic rod below to continuously apply pressure to the supporting plate until all the arc spring telescopic rods are compressed. The grinding work is also completed. The pressure applied by the arc spring telescopic rod on the supporting plate forces the speed of rotation of the supporting plate to continue to decrease, which will extend the grinding time of the sanding roller on the same part, so that the cutting gap can be polished more finely.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 12 As shown, the present invention provides a laser cutting device for processing and producing switch cabinets, comprising a laser cutting device 1 and a conveying mechanism 2, a workpiece 3 being placed on the conveying mechanism 2, and further comprising: a base 4 arranged at the bottom of the conveying mechanism 2; A grinding assembly 6 mounted on top of the base 4; A space is reserved in the middle of the conveying mechanism 2 for grinding the grinding assembly 6, and a set of rollers 22 are provided on both sides of the top of the conveying mechanism 2; The grinding assembly 6 includes a supporting plate 61 rotatably mounted on the top of the base 4. A motor 62 is fixedly mounted on the top of the base 4. A protective box 63 is fixedly mounted on the top of the base 4. The bottom of the protective box 63 is hingedly connected to a protective box 65 via a telescopic plate 64. The top of the base 4 is connected to the protective box 65 via a hydraulic rod 66. The internal bearing of the protective box 63 is equipped with a gear 1 631 and a gear 2 632 that mesh with each other. The gear 1 631 is connected to the output shaft of the motor 62. The gear 2 632 is connected to the sanding roller 634 through a transmission belt 633. The sanding roller 634 is rotatably installed inside the protective box 65, and the sanding part is located at the top of the protective box 65. The bottom of the protective box 63 is fixed with a dustproof box 60, the bottom of the dustproof box 60 is connected to the inert gas tank 69, the top of the dustproof box 60 is connected to the storage box 603 through a rubber tube 602, and the top of the storage box 603 is connected to a group of metal tubes 604 in a circumferential array, and the metal tubes 604 surround the sanding roller 634.

[0019] With the above solution, the conveying rollers 21 on the conveying mechanism 2 rotate to move the workpiece 3. The workpiece 3 gradually locates in the space reserved for the grinding assembly 6 on the conveying mechanism 2 and contacts the rollers 22. When the workpiece 3 is in the working position, it can stop. However, at this time, part of the workpiece 3 is still on the conveying rollers 21. The existence of the rollers 22 is only to support the better sliding of the workpiece 3, so as to prevent the workpiece 3 from directly contacting the top of the conveying mechanism 2, which would cause excessive friction between the two and eventually make the workpiece 3 unable to move. When the laser cutting device 1 completes one tenth of the total workload, the inert gas tank 69, the motor 62 and the hydraulic rod 1 66 are started in sequence; The gas in the inert gas tank 69 is not limited, but the gas must have cooling properties. The specific composition and concentration and other data need to be determined according to the actual working conditions. The gas in the inert gas tank 69 enters the interior of the storage box 603 through the dustproof box 60 and the rubber tube 602, and is finally discharged through several metal tubes 604. The temperature around the workpiece gap drops rapidly, thereby reducing the damage to the sanding roller 634 caused by high temperature. When the device completes its work, the temperature on the workpiece will not be too high, causing burns to the workers. When the gas is sprayed into the cutting gap, it also removes the slag and dust on it, thereby effectively improving the cutting quality. The output shaft of the motor 62 drives the gear 2 632 to rotate through the gear 1 631, and the gear 2 632 drives the sanding roller 634 to rotate through the transmission belt 633. When the speed of the sanding roller 634 stabilizes, the hydraulic rod 1 66 drives the protection box 65 to rise, and the telescopic plate 64 is stretched. Since the supporting plate 61 is movably mounted on the base 4, all the structures of the grinding assembly 6 except the motor 62 are mounted on the supporting plate 61. According to the inertia generated by the rotation of the gear 1 631 driven by the motor 62, the gear 2 632 will not rotate immediately, but guide the protection box 63 to rotate through resistance. However, due to the gravity generated by the structure on the supporting plate 61, the supporting plate 61 will cause the rotation speed of the supporting plate 61 to be slow, so as to prevent the sanding roller 634 from moving and overlapping with the laser, causing the laser to damage the sanding roller 634. Finally, the sanding roller 634 gradually polishes the cutting gap to make the cross-section of the cutting gap complete and facilitate subsequent secondary processing and installation work. This makes the device work without too much manual intervention, and the sanding roller 634 follows behind the moving trajectory of the laser, so it does not cause too much impact on the cutting work.

[0020] After cutting, the workpiece is completely separated from the raw material and falls on the top of the protective box 63. However, due to the large friction between the metals and the thickness of the workpiece, the two are temporarily stuck together. When the conveyor roller 21 drives the raw material to move, the workpiece will also move until both are completely located on the conveyor roller 21 and exit the laser cutting equipment 1. Since the cutting gap has been polished, this means that there is no adhesion problem between the workpiece and the raw material, so workers can separate the two more easily, thereby reducing the labor of the staff.

[0021] like Figures 1-9 As shown, the telescopic plate 64 includes a metal sheet 641, which is arranged at the hinge of the telescopic plate 64 and is respectively connected to the protective box 63 and the protective box 65. A group of limiting rods 642 are respectively mounted on bearings at both ends of the telescopic plate 64. There are two limiting rods 642 in each group, and the transmission belt 633 is wrapped around each group of limiting rods 642 in an "S" shape.

[0022] With the above solution, during the laser cutting process, some slag will fall, which will be blocked by the metal sheet 641, thereby preventing the slag from contacting the transmission belt 633 and causing it to be burned. The presence of each set of limit rods 642 reduces the frequency of the transmission belt 633 contacting other structures, which effectively increases the service life of the transmission belt 633, avoids the problem of frequent subsequent replacement, and also reduces the cost of use during the operation. It should be noted that the sanding roller 634 is located below the workpiece 3, and the thickness of the metal parts used for the switch cabinet components and the casing is usually not high, so the sanding roller 634 does not need to be raised too high, and the bending angle of the telescopic plate 64 and its two end structures and the bending angle of the metal sheet 641 will not be too large, thereby avoiding damage to the metal sheet 641 due to metal fatigue, which prolongs the maintenance cycle of the device and further reduces the working time and energy of the staff.

[0023] like Figure 8 As shown, two rollers 1 643 are symmetrically arranged inside the telescopic plate 64, and the side of the telescopic plate 64 is elastically connected to the roller 2 645 through the elastic component 644. The roller 2 645 is slidably arranged on the side of the telescopic plate 64, and the transmission belt 633 is guided by the roller 1 643 and wound onto the roller 2 645.

[0024] The above solution is adopted: although it is mentioned above that the sanding roller 634 does not need to be raised too high, the bending angle of the telescopic plate 64 and its end structures and the bending angle of the metal sheet 641 will not be too large, but as long as the position of the sanding roller 634 changes, the transmission belt 633 will be pulled. Although it can work normally, the frequent pulling will force the circumference of the transmission belt 633 to increase and it will not be able to return to its original state. At this time, the transmission efficiency of the transmission belt 633 will be reduced, and the loose state will also cause abnormal noises, etc., and the sanding roller 634 may slip between it and the transmission belt 633 when sanding. The elastic component 644 always supports the second roller 645. When the position of the sanding roller 634 changes, the position of the second roller 645 can be changed in real time, so that the transmission belt 633 can be continuously tightened, so that the transmission belt 633 is always in the best transmission state to avoid the above situation.

[0025] like Figure 1-Figure 7 As shown, a fan 601 connected to gear 2 632 is installed inside the dustproof box 60, an air inlet is opened at the bottom of the dustproof box 60, and the air inlet is closed by a metal filter. A hydraulic rod 3 68 is set on the top of the base 4, and an inert gas tank 69 is placed on the top of the hydraulic rod 3 68.

[0026] Adopting the above scheme: Gear 2 632 drives fan 601, and simultaneously extracts the inert gas released by the inert gas tank 69 and the external air, which can make the temperature of the gas stored in the inert gas tank 69 lower and reduce the amount of gas released, but the temperature of the gas discharged through the metal pipe 604 and the cutting gap can be normally cooled, and the inert gas tank 69 can be used for a longer time, avoiding frequent replacement by the staff, which consumes a lot of time.

[0027] like Figures 1-9 As shown, hydraulic rod 1 66 is slidably installed on the top of base 4 , hydraulic rod 2 67 is fixedly installed on the top of base 4 , and the movable end of hydraulic rod 2 67 is fixedly connected to the bottom of hydraulic rod 1 66 .

[0028] With the above solution, the hydraulic rod 2 67 can control the position of the hydraulic rod 1 66 , which means that the sanding roller 634 can not only move vertically but also change its horizontal position, thereby adapting to cutting of different shapes.

[0029] like Figures 1-4 As shown, a clamping assembly 7 is provided on both sides of the top of the base 4 and the conveying mechanism 2; The clamping assembly 7 includes a group of positioning plates 71 fixed to the top of the base 4, and positioning plates 72 are slidably installed on the positioning plates 71. A lifting plate 73 is commonly installed at the bottom of each positioning plate 72. A hydraulic rod 74 is installed on the top of the base 4, and the top of the hydraulic rod 74 is fixedly connected to the lifting plate 73.

[0030] The travel track of the workpiece 3 is located between the positioning plate 1 71 and the positioning plate 2 72 . The hydraulic rod 5 74 lifts the positioning plate 2 72 through the lifting plate 73 to a maximum height higher than the top of the conveying mechanism 2 .

[0031] The above solution is adopted: when the workpiece 3 is located in the working position, the hydraulic rod 5 74 lifts the positioning plate 2 72 through the lifting plate 73, so that the positioning plate 2 72 cooperates with the positioning plate 1 71 to clamp the workpiece 3, and at the same time disengages from the conveying mechanism 2, thereby increasing the stability of the workpiece 3 when being cut, avoiding the deviation of the cutting trajectory on the workpiece 3 and the occurrence of defective products.

[0032] like Figure 10-12 As shown, a speed limiting component 5 is provided on the top of the base 4; The speed limiting assembly 5 includes a support tube 51 fixed on the top of the base 4. A group of arc-shaped spring telescopic rods 52 are movably connected to the inner wall of the support tube 51. Each arc-shaped spring telescopic rod 52 is spirally distributed inside the support tube 51. One end of the topmost arc-shaped spring telescopic rod 52 is fixed on the base 4. A hydraulic rod four 53 is provided on the support tube 51 at the other end of the arc-shaped spring telescopic rod 52.

[0033] With the above solution, as the support plate 61 rotates, it also compresses the arc-shaped spring telescopic rod 52. The elastic force therein forces the support plate 61 to rotate more slowly, thereby preventing the laser from irradiating the grinding assembly 6 and causing damage thereto. When the topmost arc-shaped spring telescopic rod 52 cannot be compressed any more, the corresponding hydraulic rod 4 53 retracts, and the end of the upper arc-shaped spring telescopic rod 52 pushes the end of the lower adjacent arc-shaped spring telescopic rod 52, thereby continuously applying pressure to the support plate 61. Until all the arc spring telescopic rods 52 are compressed, the grinding work is also finished. The above-mentioned working process can be Figure 11 and Figure 12 As can be seen in detail, the pressure exerted by the arc-shaped spring telescopic rod 52 on the supporting plate 61 forces the rotation speed of the supporting plate 61 to continue to decrease, which will extend the sanding time of the sanding roller 634 on the same part, so that the cutting gap can be polished more finely.

[0034] The working principle and use process of the present invention: The conveying roller 21 on the conveying mechanism 2 rotates to move the workpiece 3, and the workpiece 3 is gradually positioned in the space reserved for the grinding assembly 6 on the conveying mechanism 2; When the laser cutting device 1 completes one tenth of the total workload, the inert gas tank 69, the motor 62 and the hydraulic rod 1 66 are started in sequence; The gas in the inert gas tank 69 enters the interior of the storage box 603 through the dustproof box 60 and the rubber tube 602, and is finally discharged through several metal tubes 604. The temperature around the workpiece gap drops rapidly, thereby reducing the damage to the sanding roller 634 caused by high temperature. The output shaft of the motor 62 drives the gear 2 632 to rotate via the gear 1 631, and the gear 2 632 drives the sanding roller 634 to rotate via the transmission belt 633. When the speed of the sanding roller 634 stabilizes, the hydraulic rod 1 66 drives the protection box 65 to rise, and the telescopic plate 64 is stretched. Since the supporting plate 61 is movably mounted on the base 4, all the structures in the grinding assembly 6 except the motor 62 are mounted on the supporting plate 61. According to the inertia generated by the rotation of the gear 1 631 driven by the motor 62, the gear 2 632 will not rotate immediately, but guide the protection box 63 to rotate through resistance. However, due to the gravity generated by the structure on the supporting plate 61, the supporting plate 61 will cause the rotation speed of the supporting plate 61 to be slow, so as to prevent the sanding roller 634 from moving and overlapping with the laser. Finally, the sanding roller 634 gradually polishes the cutting gap, forcing the cross-section of the cutting gap to be complete. The cut workpiece is completely separated from the raw material, and the workpiece falls on the top of the protective box 63. However, due to the large friction between the metals and the thickness of the workpiece, the two are temporarily stuck together. When the conveying roller 21 drives the raw material to move, the workpiece will also move until both are completely located on the conveying roller 21 and exit the laser cutting equipment 1.
