Description

Technical Field

[0001] The present invention relates to the technical field of cutting, and specifically to a laser cutting and blanking device and a blanking method for high and low voltage switch cabinet bodies. Background Art

[0002] The main function of a switch cabinet is to open, close, control, and protect electrical equipment during the processes of power generation, power transmission, power distribution, and power conversion in a power system; The components inside a switch cabinet mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers, and various protection devices, etc. There are many classification methods for switch cabinets. For example, they can be divided into withdrawable switch cabinets and fixed switch cabinets according to the installation method of the circuit breaker; or according to different cabinet structures, they can be divided into open switch cabinets, metal enclosed switch cabinets, and metal enclosed armored switch cabinets; According to different voltage levels, they can also be divided into high voltage switch cabinets, medium voltage switch cabinets, and low voltage switch cabinets, etc., and are mainly applicable to various different occasions such as power plants, substations, petrochemical industries, metallurgical rolling mills, light industry and textile industries, factories and mines, residential communities, high-rise buildings, etc.

[0003] The cabinet body of a switch cabinet is usually formed by welding multiple plates together, and usually, the plates need to be cut in the previous step before welding; Therefore, by searching for the cutting direction of the plates, a plate laser cutting device is disclosed, with the publication number: CN211708404U; Most of the existing cutting equipment is for vertical cutting, including but not limited to the above patent. This cutting method requires re-cutting on the subsequent cabinet body welding equipment to cut out a 45° inclined surface at the end, and the inclined surfaces are mirror - set for easy docking; Secondly, based on the above - mentioned 45° inclined cutting method, due to the different orientations of the cut surfaces, the cutting angle needs to be adjusted during cutting. Refer to the attached drawings of the specification Figure 6 ; However, the cut surfaces of this method face different directions and are relatively scattered, which is not conducive to the subsequent welding and splicing work. Therefore, a laser cutting and blanking device for high and low voltage switch cabinet bodies is provided to solve the problems of inclined cutting and non - uniform cut surfaces. Summary of the Invention

[0010] Furthermore, the second adjustment component includes two first strip plates slidably installed on the opposite sides of the two bearing seats.

[0011] Furthermore, the transmission component includes a gear set rotatably installed on the bearing seat and meshing with each other.

[0014] The present invention also provides a method for laser cutting and blanking of a high-voltage and low-voltage switchgear cabinet body. Using the above-mentioned laser cutting and blanking device for a high-voltage and low-voltage switchgear cabinet body, the method includes the following steps: Step 1: Convey the cut plate into the transfer plate by the rotation of the driving roller. Step 2: Flip and blank the plate through the turnover of the transfer plate, and adjust the cut surface of some plates at intervals at the same time.

[0015] The present invention has the following beneficial effects: (1) For the laser cutting and blanking device for a high-voltage and low-voltage switchgear cabinet body, the adjustable feeding mechanism conveys the plate at equal intervals. Among them, the adjustable feeding mechanism can be adjusted according to the thickness of the plate, so that its limitation is relatively low.

[0016] (2) For the laser cutting and blanking device for a high-voltage and low-voltage switchgear cabinet body, the opposite inclined cutting mechanism cuts the plate. Among them, the opposite inclined cutting mechanism cuts at a 45° inclination on one side and then moves to its mirror position for cutting. After this movement, its cutting position remains unchanged and the cutting angles are opposite, so that the cutting size of each plate is unified. Secondly, the power for adjusting the opposite inclined cutting mechanism comes from the adjustable feeding mechanism. That is to say, when the adjustable feeding mechanism is feeding, it drives the adjustment of the opposite inclined cutting mechanism, and the adjustment ends after the feeding ends. Therefore, there is no need for separate driving and debugging, and its use cost is lower.

[0017] (3) For the laser cutting and blanking device for a high-voltage and low-voltage switchgear cabinet body, the flipping and blanking mechanism flips and blanks the cut plate, that is, transfers the cut plate to the blanking process. Due to the characteristics of cutting, the cut surfaces of the plates are not unified, which affects the subsequent work to a certain extent. Therefore, when carrying out the transfer work, according to the law of the cut surface orientation, the flipping and blanking mechanism adjusts the cut surfaces of the plates to face the same direction, so as to facilitate the subsequent work.

[0018] (4) The laser cutting and blanking device for a high-voltage and low-voltage switchgear cabinet body has a relatively high degree of automation, can reduce the labor cost and improve the processing efficiency to a certain extent at the same time, and has relatively high practicability.

[0019] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the advantages described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] Next, according to Figures 1 - 21 Describe the laser cutting and blanking device for the high and low voltage switch cabinet body provided by the embodiment of the present invention.

[0025] As shown Figures 1 - 21 in the figure, an embodiment of the present invention provides a technical solution: a laser cutting and blanking device for a high and low voltage switch cabinet body, which includes a cutting bed 1 and a plurality of legs fixed to the bottom of the cutting bed 1, and further includes an installation groove opened on the cutting bed 1, and an adjustable feeding mechanism is installed in the installation groove; a cutting groove 101 opened on the cutting bed 1, an oppositely inclined cutting mechanism is installed above the cutting groove 101, and the oppositely inclined cutting mechanism is connected to the adjustable feeding mechanism; a blanking port opened at the end of the cutting bed 1, and a flipping blanking mechanism matched with the adjustable feeding mechanism is installed at the blanking port; two limiting members 102 arranged oppositely, and the two limiting members 102 are fixed on the cutting bed 1 for limiting the plate.

[0026] In the embodiment of the present invention, the raw material moves towards the oppositely inclined cutting mechanism through the adjustable feeding mechanism, and the movement is intermittent and equidistant. After the cutting position of the raw material moves to the position of the cutting groove 101, the movement stops, and then the cutting is carried out through the oppositely inclined cutting mechanism. Finally, the blanking is carried out through the flipping blanking mechanism.

[0027] The oppositely inclined cutting mechanism includes two sleeve plates 3 slidably installed on the cutting bed 1, and a sliding plate 301 is slidably installed on each of the two sleeve plates 3; a guiding plate 302 is rotatably installed between the two sliding plates 301, a lead screw 304 is rotatably installed on one side of the guiding plate 302, a first threaded sleeve 303 in threaded cooperation with the lead screw 304 is sleeved on the lead screw 304, the first threaded sleeve 303 is slidably matched with the guiding plate 302, and a laser cutting gun 305 is fixed on the first threaded sleeve 303; electric push rods are installed on both of the two sleeve plates 3, and the movable rods of the electric push rods are fixed to the sliding plates 301; first adjusting components are installed on opposite sides of the two sleeve plates 3, and the first adjusting components are connected to the adjustable feeding mechanism.

[0028] In the embodiment of the present invention, a main shaft rod perpendicular to the lead screw 304 is rotatably installed on the guiding plate 302. The main shaft rod is meshed with a bevel gear coaxially fixed to the end of the lead screw 304 through a bevel gear coaxially fixed to the end. A second motor is also fixed on the guiding plate 302, and the output shaft of the second motor is coaxially fixed to the main shaft rod; When the second motor works, it drives the main shaft rod to rotate through its output shaft, so that when the main shaft rod rotates, the lead screw 304 is driven to rotate through the meshing of the two bevel gears. When the lead screw 304 rotates, the first threaded sleeve 303 and the laser cutting gun 305 fixed on the first threaded sleeve 303 are driven to move along the axial direction of the lead screw 304 through the threaded cooperation with the first threaded sleeve 303. Of course, the reverse operation of the second motor corresponds to the reverse movement of the first threaded sleeve 303; When the laser cutting gun 305 works and is combined with its axial movement, it cuts the plate located at the cutting groove 101; Among them, when the adjustable feeding mechanism works, it drives the first adjusting component to work, so as to drive the laser cutting gun 305 to flip through the work of the first adjusting component.

[0029] The first adjusting component includes a first worm gear 3012 coaxially fixed at both ends of the guide plate 302, and a first worm 308 is rotatably installed on one side of the first worm gear 3012 and is matched with it; A transmission cylinder 309 is rotatably installed on the sleeve plate 3. A plurality of transmission bars are fixed on the inner wall of the transmission cylinder 309. The transmission bars are slidably matched with the transmission grooves formed on the rod body part of the first worm 308. A first gear 3010 is coaxially fixed at the end of the transmission cylinder 309, and the first gear 3010 is matched with a second rack plate 3011 fixed on the cutting bed 1; The two sleeve plates 3 are also connected to a reciprocating member installed on the cutting bed 1, and the reciprocating member is connected to the adjustable feeding mechanism.

[0030] In the embodiment of the present invention, when the adjustable feeding component works, it drives the reciprocating member to work, so as to drive the two sleeve plates 3 to move along the length direction of the cutting bed 1 when the reciprocating member works. When the sleeve plate 3 moves, it correspondingly drives the skateboard 301 and the components installed on the sleeve plate 3 and the skateboard 301 to move as a whole; When the sleeve plate 3 and the skateboard 301 move, they drive the first gear 3010 and the transmission cylinder 309 to move horizontally, and during their horizontal movement, they are engaged with the second rack plate 3011, so that the first gear 3010 and the transmission cylinder 309 rotate. When the transmission cylinder 309 rotates, it drives the first worm 308 to rotate synchronously through the cooperation of the transmission bar and the transmission groove, so as to drive the first worm gear 3012 to rotate when the first worm 308 rotates. When the two first worm gears 3012 rotate, they drive the guide plate 302 to flip. At the same time, the lifting of the skateboard 301 is driven by an electric push rod, so that the laser cutting gun 305 moves to the mirror image state. Please refer to Figure 5 ; Among them, the reciprocating member mainly drives the sleeve plate 3 and the skateboard 301 to move back and forth. The engagement between the first gear 3010 and the second rack plate 3011 directly drives the rotation of the first worm 308. For example, when moving forward, it drives the laser cutting gun 305 to flip, and when moving back, it drives the laser cutting gun 305 to flip in the opposite direction; By driving the flipping of the laser cutting gun 305, after the plate is cut, it can be in a relatively inclined state on one side, which is convenient for subsequent docking and welding and other work. Its form can be referred to Figure 6 ; It should also be noted that the electric push rod in the present invention is not shown.

[0031] The reciprocating member includes two reciprocating lead screws 307 rotatably installed on the cutting bed 1. Two second thread sleeves 306 that are threadedly engaged with the reciprocating lead screws 307 are sleeved on the two reciprocating lead screws 307, and the two second thread sleeves 306 are respectively fixed to the two sleeve plates 3; One end of the reciprocating lead screw 307 is rotatably installed with a second transmission shaft 503 perpendicular to the reciprocating lead screw 307. The second transmission shaft 503 is connected to the reciprocating lead screw 307 through a first bevel gear set 504, and the second transmission shaft 503 is also connected to an adjustable feeding mechanism.

[0032] In the embodiment of the present invention, when the adjustable feeding assembly works, it drives the second transmission shaft 503 to rotate. When the second transmission shaft 503 rotates, it drives the reciprocating lead screw 307 to rotate through the first bevel gear set 504, so that when the reciprocating lead screw 307 rotates, it drives the second thread sleeve 306 and the sleeve plate 3 to reciprocate axially along the reciprocating lead screw 307 through the threaded engagement with the second thread sleeve 306.

[0033] The adjustable feeding mechanism includes two bearing seats 2 fixed in the installation groove and arranged oppositely. Two sliders 201 are slidably installed on the opposite sides of the two bearing seats 2, and two feeding rollers 2013 are rotatably installed in the two sliders 201; The two sliders 201 on one side are connected by a second adjustment assembly, and the two feeding rollers 2013 are connected by a transmission assembly.

[0034] In the embodiment of the present invention, when the second adjustment assembly works, it drives the two sliders 201 to move relatively or in the opposite direction, so as to drive the two feeding rollers 2013 to move relatively or in the opposite direction through the relative or opposite movement of the sliders 201, so as to realize the conveying work of plates with different thicknesses; Among them, the relative rotation of the two feeding rollers 2013 is driven by the transmission assembly, and the plate between the two feeding rollers 2013 is conveyed through the relative rotation of the two feeding rollers 2013, and the thickness of the plate is not limited.

[0035] The second adjustment assembly includes two first strip plates 205 slidably installed on the opposite sides of the two bearing seats 2. The two first strip plates 205 are respectively fixed to the two sliders 201, and a driving gear 202 meshing with the two first strip plates 205 is rotatably installed between the two first strip plates 205; A third worm gear 203 is coaxially fixed on the driving gear 202. A third worm 204 that is matched with the third worm gear 203 is rotatably installed on one side of the third worm gear 203. One end of the third worm 204 is rotatably installed with a first transmission shaft 207 perpendicular to it. The first transmission shaft 207 and the third worm 204 are connected through a second bevel gear set 206, and the two first transmission shafts 207 on both sides are connected through a timing belt 2015.

[0036] In the embodiment of the present invention, one of the No. 1 transmission shafts 207 is driven to rotate manually or by a motor, so that when one of the No. 1 transmission shafts 207 rotates, the other No. 1 transmission shaft 207 is driven to rotate by a synchronous belt 2015, thereby making the two No. 1 transmission shafts 207 rotate synchronously; When the No. 1 transmission shaft 207 rotates, the No. 3 worm 204 is driven to rotate through the No. 2 bevel gear set 206. The No. 3 worm 204 rotates, and the No. 3 worm gear 203 cooperates with the No. 3 worm gear 203 to drive the two No. 3 worm gears 203 and the driving gear 202 to rotate. When the driving gear 202 rotates, the two No. 1 strips 205 and the slider 201 are driven to move relative / oppositely through meshing with the two No. 1 strips 205. By driving the two sliders 201 to move relative or oppositely to each other, the two feeding rollers 2013 can be driven to move relative or oppositely to each other, so that the distance between the two feeding rollers 2013 can be adjusted, so that plates of different thicknesses can be transported; Secondly, the present invention transmits power by cooperating between the third worm wheel 203 and the third worm 204, and can have a self-locking effect while transmitting. Correspondingly, after adjusting the two feed rollers 2013, the distance between the two feed rollers 2013 will not change due to external interference.

[0037] The transmission assembly includes a gear set 208 rotatably mounted on the bearing seat 2 and meshing with each other, two gear sets 208 are coaxially fixed with limit slide bars 209, and two limit slide bars 209 are slidably sleeved with limit slide cylinders 210; Among them, a plurality of transmission grooves are evenly spaced on the circumference of the limit slide bar 209, and a transmission bar is fixed on the circumference of the inner wall of the limit slide cylinder 2010, and the transmission bar and the transmission groove are slidably matched; A connecting frame 2014 is rotatably mounted on the limiting slide 2010, and the connecting frame 2014 is rotatably connected to the feeding roller 2013. A first helical gear 2011 is coaxially fixed on the limiting slide 2010, and the first helical gear 2011 is meshed with a second helical gear 2012 coaxially fixed on the feeding roller 2013; The two limit slide bars 209 on the same side are connected by a No. 1 transmission chain 501, and the limit slide bar 209 on the other side is connected to the No. 2 transmission shaft 503 through a No. 2 transmission chain 502; the four limit slide bars 209 on both sides are defined as: the first limit rod and the second limit rod on the left side, the third limit rod and the fourth limit rod on the right side for the convenience of description, the second limit rod and the fourth limit rod are connected by a No. 1 transmission chain 501, and the first limit rod and the third limit rod are connected to the No. 2 transmission shaft 503 through the No. 2 transmission chain 502 respectively, which can be referred to Figure 10 , Figure 16 and Figure 17 .

[0038] In an embodiment of the present invention, a motor bracket is fixed to the bottom of the cutting bed 1, and a first motor 5 is fixed to the motor bracket. The output shaft of the first motor 5 is connected to the second limiting rod and the fourth limiting rod through a first transmission chain 501, so that when the first motor 5 operates, its output shaft drives the second limiting rod and the fourth limiting rod to rotate through the first transmission chain 501. When the second limiting rod rotates, it drives the first limiting rod to rotate relatively through two gear sets 208. When the fourth limiting rod rotates, it drives the third limiting rod to rotate relatively through the gear set 208. Since the structure in this embodiment is mirror - set, only one end will be described here, and its motion state and effect are the same; When the second limiting rod rotates, it drives the first limiting rod to rotate relatively through the gear set 208, and synchronously drives the limiting sliding cylinder 2010 to rotate. When the limiting sliding cylinder 2010 rotates, it drives the feeding roller 2013 to rotate through the meshing of the second helical gear 2012 and the first helical gear 2011. Since both the two limiting sliding rods 209 and the limiting sliding cylinder 2010 rotate relatively, the rotation of the two feeding rollers 2013 driven by the second helical gear 2012 and the first helical gear 2011 is also relative rotation; Among them, when the limiting sliding rod 209 rotates, it drives the limiting sliding cylinder 2010 to rotate through the cooperation of the transmission bar and the transmission groove. Its function is that while rotating, the limiting sliding cylinder 2010 can slide axially along the limiting sliding rod 209; When the two feeding rollers 2013 move relatively or in opposite directions, it drives the limiting sliding cylinder 2010 to slide axially on the limiting sliding rod 209 through the connecting frame 2014. That is to say, the distance between the two feeding rollers 2013 can be adjusted arbitrarily, and any distance will not disengage from the transmission; It should be noted that when the limiting sliding rod 209 rotates, it also drives the second transmission shaft 503 to rotate through the second transmission chain 502; It should also be noted that rubber layers are fixed on both of the two feeding rollers 2013. During transportation, the relative movement of the two feeding rollers 2013 clamps the plate. The force of this clamping will be offset by the travel of the rubber layer, so that the extrusion force will not be all applied to the plate. At the same time, the abutting force between the rubber layer and the plate is increased to prevent relative sliding between the plate and the rubber layer, that is, the so - called "slipping".

[0039] The flipping and discharging mechanism includes a bracket 4 installed at one end of the cutting bed 1 away from the adjustable conveying mechanism. A synchronous hexagonal roller 406 is rotatably installed on the bracket 4. A hexagonal support cylinder 401 fixed to it is sleeved on the synchronous hexagonal roller 406. Transfer plates 402 are installed on six sides of the hexagonal support cylinder 401; Among them, three transfer plates 402 evenly distributed in a circumferential manner are connected to a flipping assembly installed in the hexagonal support cylinder 401, and the other three transfer plates 402 are fixed to the hexagonal support cylinder 401; A driving roller 103 is rotatably installed on the cutting bed 1. The rotating shaft of the driving roller 103 is coaxially fixed to the motor transmission shaft installed on the cutting bed 1. When the motor works, the driving roller 103 is driven to rotate by its transmission shaft.

[0040] In the embodiment of the present invention, when the plate moves to the cutting groove 101 for cutting, one end of the plate is on the driving roller 103. After the cutting is completed, the cut plate is driven by the rotation of the driving roller 103 to move into the transfer plate 402. A stepping motor is also installed on the bracket 4. The output shaft of the stepping motor is connected to the driving disk 405 rotatably installed on the bracket 4 through a bevel gear set. A driven disk 404 cooperating with the driving disk 405 is coaxially fixed on the synchronous hexagonal roller 406. When the stepping motor works, its output shaft drives the driving disk 405 to rotate one circle through the bevel gear set. When the driving disk 405 rotates one circle, the driven disk 404 is driven to rotate one-sixth. At the same time, the synchronous hexagonal roller 406, the hexagonal support cylinder 401, and the transfer plate 402 are driven to rotate synchronously through the driven disk 404, thereby realizing the equal-angle rotation of the transfer plate 402, so that there will be a transfer plate 402 in the waiting position each time the hexagonal support cylinder 401 and the transfer plate 402 rotate. Therefore, each time after cutting, when the material is discharged through the driving roller 103, the cut plate can move into the transfer plate 402. Secondly, when the hexagonal support cylinder 401 and the transfer plate 402 rotate, the flipping assembly is also driven to work, and the transfer plate 402 connected to the flipping assembly is driven to rotate through the flipping assembly.

[0041] It should also be noted that the driven disk 404 and the driving disk 405 are the application of the Maltese cross mechanism in the prior art. Since it is the prior art, its specific working principle will not be elaborated. Among them, when the driving disk 405 rotates one circle, the driven disk 404 is driven to rotate one-sixth, and when the driven disk 404 is not driven to rotate, the driving disk 405 applies locking to the driven disk 404.

[0042] The flipping assembly includes three second worm wheels 408 rotatably installed in the hexagonal support cylinder 401 and arranged at equal circumferential intervals. One side of each of the three second worm wheels 408 is rotatably installed with a second worm 409 cooperating therewith. Both ends of the three second worms 409 are coaxially fixed with second gears 4010. An installation frame 403 is fixed at the end of the cutting bed 1. An internal gear ring 407 is arranged in the installation frame 403, and the internal gear ring 407 cooperates with the three second gears 4010. Among them, six transfer plates 402 are arranged at equal circumferential intervals on the hexagonal support cylinder 401. Three of them are rotatably connected to the hexagonal support cylinder 401, and the rotating shaft is coaxially fixed to the second worm wheel 408, and the other three are fixed to the hexagonal support cylinder 401.

[0043] In an embodiment of the present invention, the internal gear ring 407 is an incomplete gear ring; When the hexagonal support cylinder 401 rotates, it drives the synchronous hexagonal roller 406 to rotate synchronously, so that the three second worm gears 409 rotate circumferentially with the synchronous hexagonal roller 406 as the axis; When the second worm gear 409 rotates circumferentially, it drives the second worm gear 409 to rotate through the meshing of the second gear 4010 and the internal gear ring 407. This rotation refers to self-rotation during circumferential rotation. When the second worm gear 409 rotates self, it drives the transfer plate 402 connected to the second worm gear 408 to rotate through the cooperation with the second worm gear 408. After the transfer plate 402 rotates 180° self, the second gear 4010 disengages from the internal gear ring 407; Then, when the transfer plate 402 rotates 180° with the synchronous hexagonal roller 406 as the axis, blanking is carried out. After the transfer plate 402 completes blanking, it will mesh with the internal gear ring 407 again during the subsequent 180° rotation with the synchronous hexagonal roller 406 as the axis, so that the transfer plate 402 rotates 180° self again and returns to the initial state; The transfer plate 402 fixed on the hexagonal support cylinder 401 can only be flipped and cannot rotate self; Please refer to Figure 18 and Figure 20 . Simply put, the cut plates have alternating front and back cutting surfaces. When the transfer plate 402 carries the plate and flips 180° while rotating 180° self, the effect is that the cutting surface orientation is not changed during flipping and blanking; The transfer plate 402 that can only be flipped and cannot rotate self will flip the plate 180°. The above-mentioned self-rotating and non-self-rotating work alternately, so that the self-rotating station can only act on the plate with the cutting surface facing down, and the non-self-rotating station can only act on the plate with the cutting surface facing up. By this method, the cutting surfaces of the blanking can be unified, which is convenient for subsequent operations.

[0044] The above-mentioned transfer plate 402 rotates on the hexagonal support cylinder 401. In order to avoid interference between one transfer plate 402 and the transfer plates 402 on both sides during rotation, the diameter of the hexagonal support cylinder 401 can be increased, such as Figure 20 shown.

[0045] The hexagonal support cylinder 401 can also be set to a square or a triangle, etc. Of course, the angle of each rotation of the hexagonal support cylinder 401 needs to be adjusted accordingly, that is, the matching ratio between the driven disk 404 and the driving disk 405 is adjusted to control the angle of driving the driving disk 405 and the hexagonal support cylinder 401 to rotate, such as Figure 21 shown. In actual production, it can be selected according to actual production, and the present invention does not make specific limitations.

[0046] Secondly, the above-mentioned blanking is carried out after the sheet material is rotated 180° through the transfer plate 402. The sheet material is conveyed to the rear conveyor belt 6 by two relatively rotating blanking wheels 601 and conveyed by the conveyor belt 6. Of course, stacking can also be carried out. The blanking wheels 601 are rotatably installed on the conveyor belt 6.

[0047] The above-mentioned transfer plate 402 is rectangularly arranged, and one end is open, and the sheet material can be inserted into the opening.

[0048] It should also be noted that the six transfer plates 402 are arranged at equal circumferential intervals. Among them, the first, third, and fifth are rotatably installed, and the rotating shafts are coaxially fixed with the second worm gear 408, that is, they can rotate while flipping; The second, fourth, and sixth are fixed on the hexagonal support cylinder 401, that is, they can only flip the sheet material and cannot rotate.

[0049] The specific process of the present invention is that the sheet material is evenly conveyed through the adjustable feeding mechanism. When the sheet material is moved to the cutting position (the position of the cutting groove 101), the sheet material is inclinedly cut by the oppositely inclined cutting mechanism; After cutting is completed, the cut sheet material is conveyed by the driving roller 103 so that the sheet material is inserted into the transfer plate 402 of the flipping and blanking mechanism. When the flipping and blanking mechanism works, the cut sheet material is transferred and blanked, and the cut surfaces of the cut sheet material are unified.

[0050] The present invention also provides a method for laser cutting and blanking of a high-voltage and low-voltage switch cabinet body. Using the above-mentioned laser cutting and blanking device for a high-voltage and low-voltage switch cabinet body, it includes the following steps: Step 1: Convey the cut sheet material into the transfer plate 402 by the rotation of the driving roller 103; Step 2: Flip and blank the sheet material through the turnover of the transfer plate 402, and adjust the cut surfaces of some sheet materials at intervals at the same time.
