Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a precision cutting and punching machine for switch cabinet metal housings. Background Technology

[0002] Switchgear, as a critical power distribution device in power systems, typically uses materials such as cold-rolled steel sheets, galvanized sheets, or stainless steel sheets to manufacture its metal casing, which is gradually formed through processes such as cutting, punching, bending, and welding. Among these processes, cutting and punching are core early stages that directly determine the basic structural dimensions, hole accuracy, and surface quality of the casing, thereby affecting subsequent assembly efficiency and overall equipment reliability.

[0003] Patent application number CN202323630365 discloses an integrated cutting and punching machine for grain silo panels, including a machine base. A support is fixedly connected to the top side of the machine base, and a hydraulic press is fixedly connected to the top center of the support. The drive end of the hydraulic press is fixedly connected to the top of a crossbeam. A cutting machine body is fixedly connected to the bottom inner side of the crossbeam. A translation mechanism is provided on the side of the crossbeam, and a sliding groove is provided inside the crossbeam. A cylinder is slidably connected inside the sliding groove, and a retracting mechanism is provided inside the cylinder. In this patent, the translation mechanism achieves the effect of adjusting the distance between the cutting machine body and the punching machine body. The distance can be adjusted according to the needs to facilitate punching at different punching positions, improving the applicability and production efficiency of the device. The retracting mechanism allows the punching machine body to be retracted into the cylinder, reducing the impact on the cutting operation.

[0004] The aforementioned patent, through its translation and retraction mechanisms, can indeed adjust the spacing according to requirements to facilitate punching at different punching positions, and retract the punching machine body into the cylinder to reduce the impact on the cutting operation. However, because the production of switch cabinets typically requires cutting complex metal plate contours, conventional circular saw cutting is inefficient, and relying on fixed molds for long-term use can lead to decreased processing accuracy due to wear and tear, as well as high equipment wear and tear costs. Summary of the Invention

[0005] In order to overcome the defects in the prior art, the purpose of this invention is to provide a precision cutting and punching machine for the metal housing of switch cabinets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a precision cutting and punching integrated machine for the metal housing of switch cabinets, including a base frame and a metal plate placed on its top surface, as well as several coordinate buckles, two slide rail beams symmetrically arranged on the base frame, and a moving device slidably connected on the slide rail beams. A telescopic positioning beam is connected between the two moving devices, and another moving device is slidably connected on the telescopic positioning beam. A laser cutting head is installed at the bottom of this moving device. Several of the aforementioned coordinate buckles are slidably connected to the front edge and left and right edges of the base frame; The moving device includes a sliding box, two pairs of clamping petals rotatably connected to both sides of the sliding box, a vertical rack meshing with the rotating end of each pair of clamping petals, and a linkage sliding frame for driving the two vertical racks to rise and triggering the lower ends of each pair of clamping petals to close together. The telescopic positioning beam includes a positioning beam and telescopic plugs that are slidably connected at both ends of the positioning beam. The two telescopic plugs are respectively inserted into two coordinate buckles at the left and right edges for positioning. A punching device is slidably connected to the top of the base frame. The punching device includes a long slide rail, an L-shaped support rod slidably sleeved on the long slide rail, a hydraulic cylinder fixedly installed at the rear of the L-shaped support rod, an extrusion block slidably connected to the L-shaped support rod, a lifting block slidably connected to the L-shaped support rod, and a punching cutter head for punching holes vertically fixed at the bottom surface of the lifting block.

[0007] As a further improvement to this technical solution, the base frame includes a base plate, support legs, a clamping plate fixed on the base plate, a top plate fixed on the clamping plate, a heightening rod correspondingly fixed to the bottom of the coordinate buckle, and a worktable fixedly installed on the top plate. A base is fixedly provided at the lower end of the heightening rod, and a sliding sleeve is slidably sleeved on the outside of the heightening rod. The sliding sleeve and the corresponding base are clamped at the edge of the top plate, and a connecting rod is fixed between the two corresponding heightening rods on the left and right.

[0008] As a further improvement to this technical solution, the coordinate buckle is square in shape and has symmetrical triangular grooves on its inner side wall. An extension block is also connected between the coordinate buckle in the front row and the corresponding heightening rod. A protrusion is fixed on the outer wall of the sliding box below the vertical rack. A pull spring for resetting and opening the clamping flap is connected between the protrusion and the corresponding vertical rack. A movable gear is fixed at the upper end of the clamping flap. Each vertical rack meshes with two movable gears on the same side. A servo motor for driving the moving device to slide is provided inside the sliding box. A gear is coaxially connected to the output shaft of the servo motor. Another gear is rotatably connected inside the sliding box, and the two gears mesh with each other.

[0009] As a further improvement to this technical solution, the top surface of the coordinate buckle in the front row is provided with two mutually symmetrical extension rods. The rear end of the extension rod is provided with an upper cylindrical magnet. A plug for inserting the coordinate buckle in the front row is provided on the sliding box. An electromagnet is fixedly provided at the top inside the sliding box. The linkage slide frame is equipped with a lower cylindrical magnet at each of the two upper cylindrical magnets near both ends. An iron plate is provided in the middle of the linkage slide frame. After the telescopic positioning beam drives the plug to slide into the coordinate buckle, the opened electromagnet and the upper cylindrical magnet lift the linkage slide frame through magnetic force, thereby driving the vertical rack to rise, and then driving the rotating clamp to clamp the telescopic positioning beam.

[0010] As a further improvement to this technical solution, a snap-fit ​​buckle is provided on the rear side wall of one of the sliding boxes slidably connected to the telescopic positioning beam. A cantilever for suspending and fixing the snap-fit ​​buckle is connected between the snap-fit ​​buckle and the sliding box. An extension block is connected between the electromagnet and the inner wall of the sliding box. Several rollers are rotatably connected between the inner walls of the sliding box. Several rollers are also rotatably connected to the inner wall of the sliding box. The rollers and rollers are always rolling and rubbing against the outer surface of the telescopic positioning beam.

[0011] As a further improvement to this technical solution, the positioning beam is perpendicular to the slide rail beam. A bottom groove is formed at the bottom of the positioning beam, and a disc is rotatably connected to the center of the bottom surface of the groove. Two connecting rods are hinged to the bottom surface of the disc near the edge. Inner protrusions are fixed on both side walls of the two ends of the positioning beam, and outer protrusions are fixed on both side walls of the telescopic plug. A transverse spring connects the inner and outer protrusions. A slide bar is fixedly connected to the bottom of the telescopic plug towards the center of the positioning beam, and the slide bar is slidably connected in the bottom groove. The end of the slide bar near the disc is hinged to the corresponding connecting rod. A rotary motor for driving the disc to rotate is also installed inside the positioning beam. When the disc rotates, the disc can drive the connecting rod to pull back or push out the slide bar, so that the telescopic plugs at both ends extend and retract into the corresponding two coordinate buckles.

[0012] As a further improvement to this technical solution, a flat rack is provided on the top surface of the positioning beam, and the lower gear meshes with the corresponding flat rack; the linkage slide frame never contacts the gear, the roller or the roller, and the roller never contacts the gear or the flat rack; the two moving devices on the left and right sides do not have the clamping flap, the vertical rack, the linkage slide frame or the electromagnet.

[0013] As a further improvement to this technical solution, trapezoidal sliders are slidably connected to the top surface of the workbench on both the left and right sides. A long slide rail is fixedly connected between the two trapezoidal sliders, and the long slide rail is perpendicular to the L-shaped support rod. The L-shaped support rod includes a shorter vertical section and a longer horizontal section. A fixed plate is vertically installed on the rear top surface of the horizontal section. The hydraulic cylinder is vertically installed on the front side wall of the fixed plate. A support plate is installed at the rear end of the top plate. A ball bearing for sliding arbitrarily on the top surface of the support plate is installed at the lower end of the fixed plate. Triangular stabilizing frames are also installed on both sides of the fixed plate. A telescopic rod is installed in front of the hydraulic cylinder, and the front end of the telescopic rod is fixedly connected to the extrusion block.

[0014] As a further improvement to this technical solution, a T-shaped slider is fixedly provided on the top surface of the extrusion block, and a sliding shell is provided on the horizontal section of the L-shaped support rod corresponding to the bottom surface of the T-shaped slider. The upper part of the T-shaped slider is slidably sleeved in the sliding shell. A slide rail is provided on the top surface of the horizontal section of the L-shaped support rod at the center line, and a vertical top piece is provided on the top surface of the T-shaped slider. The vertical top piece is slidably inserted into the slide rail. The sliding directions of the extrusion block, the vertical top piece, and the telescopic rod are all parallel to the horizontal section of the L-shaped support rod.

[0015] As a further improvement to this technical solution, both the extrusion block and the lifting block are prisms with a right-angled trapezoid as the base. They are in contact with each other and slidably connected at the inclined surface. The lifting block is also slidably connected to the rear side wall of the vertical section of the L-shaped support rod. When the extrusion block slides forward, the lifting block can be extruded and slide downward. Two upper protrusions are symmetrically arranged on the two side walls of the L-shaped support rod, and two lower protrusions are symmetrically arranged on the two side walls of the lifting block. A return spring is connected between the upper protrusion and the lower protrusion on the same side. The return spring is parallel to the vertical section of the L-shaped support rod. A cross-shaped plug is slidably connected to the front of the top surface of the L-shaped support rod. A rearwardly extending triangular protrusion is fixedly provided at the bottom of the cross-shaped plug. The front end of the vertical top plate has an inclined surface corresponding to the triangular protrusion, which cooperates with the triangular protrusion. When the vertical top plate slides backward with the pressing block, the triangular protrusion slides down along the inclined surface of the vertical top plate, so that the cross-shaped plug can descend and disengage from the snap-fit. When the vertical top plate slides forward, the inclined surface of the triangular protrusion rises along the inclined surface of the vertical top plate, so that the cross-shaped plug can rise and insert into the cross groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This integrated precision cutting and punching machine for switchgear metal casings utilizes a base frame, coordinate clips, slide rail beams, a moving device, a telescopic positioning beam, and a laser cutting head. The moving device includes a plug, and the telescopic positioning beam includes telescopic plugs at both ends for inserting into the coordinate clips. When cutting metal plates, the operator can control the moving device to align and insert the plugs into preset coordinate clips, or control the telescopic plugs to align and insert them into preset coordinate clips. This allows the laser cutting head to align with and lock onto the position requiring a straight cut. After aligning with the corresponding coordinate clips, the machine can slide and cut the metal plate in a straight line in an orthogonal direction to the alignment direction. This achieves precise metal plate cutting and reduces errors caused by repeated cutting and resetting.

[0017] 2. This integrated precision cutting and punching machine for the metal casing of switchgear utilizes a punching device. A cross-shaped plug is vertically slidably connected to an L-shaped support rod, and a vertical top plate is mounted on the extrusion block. When punching is required, a hydraulic cylinder drives a telescopic rod forward, causing the inclined surface of the triangular protrusion to rise along the inclined surface of the vertical top plate. This allows the cross-shaped plug to rise and insert into the cross slot. The punching head can then be aligned to the appropriate position using the same operating mechanism as for cutting. This allows for repeated positioning of the punching location using the moving device, with pressure from the horizontally placed hydraulic cylinder transmitted through the inclined surface for punching. The combination of cutting and punching improves work efficiency. Attached Figure Description

[0022] Please see Figures 1-18 As shown, the present invention provides a precision cutting and punching integrated machine for the metal shell of switch cabinet, including a base frame 1, several coordinate buckles 2, a metal plate 3 placed on the top surface of the base frame 1, two slide rail beams 4 symmetrically arranged on the base frame 1, and a moving device 5 slidably connected on the slide rail beams 4. A telescopic positioning beam 6 is connected between the two moving devices 5, and another moving device 5 is slidably connected on the telescopic positioning beam 6. A laser cutting head 7 is installed at the bottom of this moving device 5.

[0023] Several coordinate buckles 2 are slidably connected to the front edge and left and right edges of the base frame 1; The moving device 5 includes a sliding box 50, two pairs of clamping petals 52 rotatably connected to both sides of the sliding box 50, a vertical rack 53 meshing with the rotating end of each pair of clamping petals 52, and a linkage sliding frame 54 for driving the two vertical racks 53 to rise and triggering the lower ends of each pair of clamping petals 52 to close together. The telescopic positioning beam 6 includes a positioning beam 60 and telescopic plugs 61 that are slidably connected to both ends of the positioning beam 60. The two telescopic plugs 61 are respectively inserted and positioned with two coordinate buckles 2 at the left and right edges.

[0024] A punching device 8 is slidably connected to the top of the base frame 1. The punching device 8 includes a long slide rail 80, an L-shaped support rod 81 slidably sleeved on the long slide rail 80, a hydraulic cylinder 82 fixedly installed at the rear of the L-shaped support rod 81, an extrusion block 83 slidably connected to the L-shaped support rod 81, a lifting block 84 slidably connected to the L-shaped support rod 81, and a punching cutter head 85 for punching that is vertically fixed at the bottom surface of the lifting block 84.

[0025] Specifically, the base frame 1 includes a base plate 10, support legs 101, a clamping plate 11 fixed on the base plate 10, a top plate 12 fixed on the clamping plate 11, an extension rod 13 fixed to the bottom of the coordinate buckle 2, and a worktable 14 fixed on the top plate 12. A base 130 is fixed at the lower end of the extension rod 13, and a sliding sleeve 131 is slidably sleeved on the outside of the extension rod 13. The sliding sleeve 131 and the corresponding base 130 are clamped at the edge of the top plate 12. A connecting rod 132 is fixed between the two corresponding extension rods 13 on the left and right sides so that the positions of the two corresponding coordinate buckles 2 on the left and right sides can be synchronized. When the extension rod 13 slides to the appropriate position, the edge of the top plate 12 can be clamped by tightening the bolt between the sliding sleeve 131 and the corresponding base 130, thereby providing a coordinate buckle 2 with a precise position and available for docking for the plug 502 or the telescopic plug 61 during cutting and positioning.

[0026] Specifically, the coordinate buckle 2 is square in shape and has symmetrical triangular grooves on its inner side wall. The front coordinate buckle 2 is also connected to the corresponding heightening rod 13 by an extension block 20 so that the front coordinate buckle 2 can contact the plug 502. A protrusion 501 is fixed on the outer wall of the sliding box 50 below the vertical rack 53. A pull spring 530 for resetting and opening the clamping flap 52 is connected between the protrusion 501 and the corresponding vertical rack 53. A movable gear 520 is fixed at the upper end of the clamping flap 52. Each vertical rack 53 meshes with two movable gears 520 on the same side. When the electromagnet 55 is energized and the two upper cylindrical magnets 210 are aligned with the two lower cylindrical magnets 540, the magnetic attraction between the upper and lower cylindrical magnets, plus the attraction between the electromagnet 55 and the iron piece 541, causes the linkage slide frame 54 to rise. The electromagnet 55 contacts and attracts the iron piece 541, and the vertical rack 53 rises, causing the movable gear 520 to rotate. The clamping flap 52 clamps the positioning beam 60, at which point the laser cutting head 7 can slide linearly along the direction parallel to the slide rail beam 4. When the electromagnet 55 is de-energized and demagnetized, the magnetic attraction between the electromagnet 55 and the iron plate 541 disappears, and the pull spring 530 pulls the corresponding vertical rack 53 downward to slide downward, thereby driving the movable gear 520 and causing the clamping flap 52 to loosen, so that the corresponding moving device 5 can slide along the telescopic positioning beam 6. The sliding box 50 is equipped with a servo motor 510 for driving the moving device 5 to slide. A gear 51 is coaxially connected to the output shaft of the servo motor 510, and another gear 51 is rotatably connected inside the sliding box 50, and the two gears 51 mesh with each other.

[0027] Specifically, the top surface of the front row coordinate buckle 2 is provided with two symmetrical extension rods 21. The rear end of the extension rod 21 is provided with an upper cylindrical magnet 210. The sliding box 50 is provided with a plug 502 for inserting the front row coordinate buckle 2. An electromagnet 55 is fixedly installed at the top inside the sliding box 50. Near the two ends of the linkage slide frame 54, a lower cylindrical magnet 540 is installed corresponding to the two upper cylindrical magnets 210. An iron plate 541 is provided in the middle of the linkage slide frame 54. After the telescopic positioning beam 6 drives the plug 502 to slide into the coordinate buckle 2, the opened electromagnet 55 and the upper cylindrical magnet 210 lift the linkage slide frame 54 through magnetic force, thereby driving the vertical rack 53 to rise, and then driving the rotating clamp 52 to clamp the telescopic positioning beam 6.

[0028] In addition, a snap fastener 503 is provided on the rear side wall of one of the sliding boxes 50 that is slidably connected to the telescopic positioning beam 6. A cantilever 5031 for suspending and fixing the snap fastener 503 is connected between the snap fastener 503 and the sliding box 50. An extension block 550 is connected between the electromagnet 55 and the inner wall of the sliding box 50 to fix the electromagnet 55 directly above the iron plate 541. Several rollers 56 are rotatably connected between the inner walls of the sliding boxes 50. Several rollers 57 are also rotatably connected to the inner walls of the sliding boxes 50. The rollers 56 and rollers 57 are always rolling and rubbing against the outer surface of the telescopic positioning beam 6, so that the moving device 5 can achieve linear sliding more stably and accurately.

[0029] It is worth noting that the positioning beam 60 is perpendicular to the slide rail beam 4. A bottom groove 600 is provided at the bottom of the positioning beam 60. A T-shaped strip 602, which allows the telescopic plug 61 to slide stably in a straight line, is also fixedly installed on the positioning beam 60 at the position of the telescopic plug 61. A disc 603 is rotatably connected to the center of the bottom surface of the bottom of the bottom groove 600. Two connecting rods 604 are hinged to the bottom surface of the disc 603 near its edge. Inner protrusions 601 are fixedly installed on both sides of the positioning beam 60, and outer protrusions 610 are fixedly installed on both sides of the telescopic plug 61. A transverse spring 62 connects the inner and outer protrusions 601 and 610. The bottom of the telescopic plug 61 faces the positioning beam 60. A slider 611 is fixedly connected at the center and slidably connected in the bottom groove 600. The end of the slider 611 near the disc 603 is hinged to the corresponding connecting rod 604. The positioning beam 60 is also equipped with a rotary motor 6030 for driving the disc 603 to rotate. When the disc 603 rotates, the disc 603 can drive the connecting rod 604 to pull back or push out the slider 611, so that the telescopic plugs 61 at both ends are extended and inserted into the corresponding two coordinate buckles 2. Then, the positioning beam 60 is positioned and fixed by the coordinate buckles 2. The moving device 5 on the positioning beam 60 can move linearly along the positioning beam 60 to cut the metal plate 3, along with the laser cutting head 7 at the bottom.

[0030] In addition, a flat rack 605 is provided on the top surface of the positioning beam 60, and the lower gear 51 meshes with the corresponding flat rack 605; when the servo motor 510 is not powered on, all moving devices 5 are in a non-self-locking state that can slide due to external force; the linkage slide frame 54 never contacts the gear 51, roller 56 or roller 57, and the roller 56 never contacts the gear 51 or flat rack 605; the two moving devices 5 on the left and right sides are not equipped with clamping petals 52, vertical racks 53, linkage slide frames 54 or electromagnets 55, and the two moving devices 5 on the left and right sides are connected to the coordinate buckles 2 on the left and right sides through the telescopic plug 61, without the need for magnetic force.

[0031] Specifically, trapezoidal sliders 801 are slidably connected to the top surface of the workbench 14 on both the left and right sides. A long slide rail 80 is fixedly connected between the two trapezoidal sliders 801. The long slide rail 80 is perpendicular to the L-shaped support rod 81. The L-shaped support rod 81 includes a shorter vertical section and a longer horizontal section. A fixing plate 810 is vertically installed on the rear top surface of the horizontal section. A hydraulic cylinder 82 is vertically installed on the front side wall of the fixing plate 810. A support plate 15 is installed at the rear end of the top plate 12. A ball bearing 8101 for sliding arbitrarily on the top surface of the support plate 15 is installed at the lower end of the fixing plate 810. Triangular stabilizing frames 8102 are also installed on both sides of the fixing plate 810. A telescopic rod 820 is installed in front of the hydraulic cylinder 82. The front end of the telescopic rod 820 is fixedly connected to the extrusion block 83 to fix the hydraulic cylinder 82 and make the back-and-forth sliding of the extrusion block 83 more stable.

[0032] Specifically, a T-shaped slider 830 is fixedly installed on the top surface of the extrusion block 83, and a sliding shell 813 is installed on the horizontal section of the L-shaped support rod 81 corresponding to the bottom surface of the T-shaped slider 830. The upper part of the T-shaped slider 830 is slidably sleeved in the sliding shell 813. A slide rail 811 is opened at the center line on the top surface of the horizontal section of the L-shaped support rod 81, and a vertical top piece 831 is installed on the top surface of the T-shaped slider 830. The vertical top piece 831 is slidably inserted into the slide rail 811. The sliding directions of the extrusion block 83, the vertical top piece 831, and the telescopic rod 820 are all parallel to the horizontal section of the L-shaped support rod 81, so that the extrusion block 83, the vertical top piece 831, and the telescopic rod 820 can all be controlled by the hydraulic cylinder 82 and slide synchronously.

[0033] Specifically, both the extrusion block 83 and the lifting block 84 are prisms with a right trapezoid as the base. They are in contact with each other and slidably connected at the inclined surface. The lifting block 84 is also slidably connected to the rear side wall of the vertical section of the L-shaped support rod 81. When the extrusion block 83 slides forward, the lifting block 84 can be extruded and slide downward, thereby driving the punching head 85 to move downward to open a hole in the metal plate 3. Two upper protrusions 812 are symmetrically arranged on the two side walls of the L-shaped support rod 81, and two lower protrusions 840 are symmetrically arranged on the two side walls of the lifting block 84. A return spring 841 is connected between the upper protrusion 812 and the lower protrusion 840 on the same side. The return spring 841 is parallel to the vertical section of the L-shaped support rod 81, so that after the hole is opened and the telescopic rod 820 retracts backward, the return spring 841 can drive the lifting block 84 and the punching head 85 to lift upward and detach from the metal plate 3.

[0034] A cross-shaped plug 86 is slidably connected to the front of the top surface of the L-shaped support rod 81. Two vertical slide rails 860 for sliding connection of the cross-shaped plug 86 are also vertically fixed to the top surface of the L-shaped support rod 81. A rearwardly extending triangular protrusion 861 is fixedly provided at the bottom of the cross-shaped plug 86. The front end of the vertical top plate 831, corresponding to the triangular protrusion 861, has an inclined surface that mates with the triangular protrusion 861. When the vertical top plate 831 slides backward with the pressing block 83, the triangular protrusion 861 slides down the inclined surface of the vertical top plate 831, thereby allowing the cross-shaped plug 86 to descend and disengage from the latch 503. When the vertical top plate 831 slides forward, the triangular protrusion 861... The inclined surface rises along the inclined surface of the vertical top plate 831, so that the cross plug 86 can rise and be inserted into the cross groove 5030. After the cross plug 86 is inserted into the cross groove 5030, the inclined surface of the vertical top plate 831 can continue to slide forward with the extrusion block 83, passing over the inclined surface of the triangular protrusion 861 and sliding to below the triangular protrusion 861. After passing over, the height of the cross plug 86 remains unchanged and can always be inserted into the cross groove 5030. When the cross plug 86 is inserted into the cross groove 5030, the punching head 85 is relatively fixed to the moving device 5 that is slidably connected to the positioning beam 60, and the punching head 85 can be synchronously driven by the moving device 5.

[0035] The working principle of this invention is as follows: First, the worker needs to place the metal plate 3 in a suitable position on the workbench 14. Then, the worker needs to use a measuring tool to slide the coordinate buckles 2 on the front row and the left and right sides and clamp the top plate 12 at the edge by tightening the bolts between the sliding sleeve 131 and the corresponding base 130; or by inserting the plug 502 and the telescopic plug 61 into the coordinate buckles 2 and then using the corresponding moving device 5 to drive the coordinate buckles 2 to a suitable position and clamp the top plate 12 at the edge by tightening the bolts between the sliding sleeve 131 and the corresponding base 130. Through the above methods, the positions of multiple coordinate buckles 2 corresponding to the cutting points can be fixed. If a straight cut is required along the direction of the positioning beam 60, the corresponding servo motor 510 is started to slide the telescopic positioning beam 6 to the approximate position of the pre-set coordinate buckle 2, and the corresponding servo motor 510 is turned off. Then, the rotation motor 6030 is started, so that the disc 603 rotates and drives the connecting rod 604 to push the slide bar 611. The slide bar 611 then pushes the telescopic plug 61 to insert into the triangular groove of the coordinate buckle 2. As the telescopic plugs 61 at both ends are fully inserted and contact the triangular groove wall of the corresponding coordinate buckle 2, the positioning beam 60 gradually aligns to the precise straight cut position. Then, the rotation motor 6030 is turned off, and the moving device 5 on the positioning beam 60 is started, thereby driving the laser cutting head 7 to cut along the straight line of the positioning beam 60. If a straight cut is required along the direction of the slide beam 4, first activate the moving device 5 on the positioning beam 60 to move the plug 502 to the approximate position of the pre-set front coordinate buckle 2, and ensure that the servo motor 510 of the moving device 5 sliding on the positioning beam 60 is de-energized and the electromagnet 55 is energized and activated; then, by activating the servo motors 510 on both sides, slide the telescopic positioning beam 6 towards the front of the integrated machine, so that the plug 502 slides forward until the plug 502 is fully inserted and contacts the triangular groove wall of the corresponding coordinate buckle 2. During this process, the positioning beam 6... The sliding device 5 gradually aligns with the precise straight cutting position; thus, the two upper cylindrical magnets 210 align with the two lower cylindrical magnets 540. The magnetic attraction between the upper and lower cylindrical magnets, plus the attraction between the electromagnet 55 and the iron plate 541, causes the linkage slide frame 54 to rise. The electromagnet 55 contacts and attracts the iron plate 541, the vertical rack 53 rises, causing the movable gear 520 to rotate, and the clamping flap 52 clamps the positioning beam 60. At this time, the servo motors 510 in the sliding devices 5 on both sides are started again to slide backward to perform straight cutting along the direction of the slide beam 4. After cutting, if punching is required, the control moving device 5 moves the snap fastener 503 above the cross plug 86, and then the hydraulic cylinder 82 is activated to drive the telescopic rod 820 to extend forward. As a result, the inclined surface of the triangular protrusion 861 rises along the inclined surface of the vertical top plate 831, so that the cross plug 86 can rise and be inserted into the cross groove 5030. At this time, the moving device 5 can be activated in the same way as the cutting to control the punching head 85 to be aligned with the appropriate position. After alignment, the hydraulic cylinder 82 is activated again to drive the telescopic rod 820 to extend forward. As the extrusion block 83 slides forward, the lifting block 84 can be extruded and slide downward, thereby driving the punching head 85 to move downward to open a hole in the metal plate 3.
