Description

Technical Field

[0001] The present invention relates to the field of door and window processing, and specifically to a laser cutting device for metal door and window processing. Background Technique

[0002] Metal doors and windows mainly refer to door and window products made of metal materials (such as aluminum alloy, steel, etc.). They play an important role in the construction industry and are widely used in residential, commercial, industrial, and public buildings and other fields.

[0003] A Chinese patent discloses a laser cutting device for metal door and window processing (publication number CN217551480U). This patent includes a fixed plate, on which a lifting device is installed, a cross bar is installed on the lifting device, a mounting plate is installed on the cross bar, a cutting device is installed below the mounting plate, a rotating shaft is fixedly arranged on the cutting device, a locking mechanism for locking the rotating shaft is installed on the rotating shaft, and motion devices for driving the rotating shaft to lift are installed on both sides above the rotating shaft; when it is necessary to adjust the angle of the cutting device, after rotating the rotating shaft and fixing the rotating shaft through the locking component, the cutting device can be fixed. When it is necessary to adjust the angle of the other side of the cutting device, the rotating shaft is deflected through the motion device, and the other angle of the cutting device can be offset. Through the above operations, the angle of the cutting device can be quickly adjusted.

[0004] Therefore, based on the above search and combined with the existing ones, when the above device is in use, it is impossible to directly cool the edges of the door and window after cutting. If the heat generated during cutting cannot be dissipated in time, it may cause the edges of the door and window to continue to be heated and problems such as deformation, melting, or thermal cracks may occur, affecting the appearance and quality of the door and window. Additionally, additional processing is required to repair these problems, increasing the production cost and time. Moreover, if the operator does not take appropriate protective measures when handling the just-cut door and window and directly touches the high-temperature edge, it may cause skin burns, affecting their work efficiency and safety. Summary of the Invention

[0016] Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. When the present invention is in use, by setting a water spray pipe, during the use process, when the ejector rod moves downward, it can drive the special-shaped push block to move downward, so that the special-shaped push block pushes the water baffle to slide out between the water spray pipe and the connecting pipe, and then the outer walls of both ends of the silica gel bag are squeezed by two groups of clamp shells, so that the water stored inside the silica gel bag flows upward through the water spray pipe to spray and cool one side edge of the just-cut metal door and window, thereby avoiding the problem that the metal door and window is prone to deformation and melting due to high temperature.

[0019] 2. When the present invention is in use, by setting a bimetallic strip, when the laser cutting head cuts a part of the metal door and window on the top of a group of ejector rods, the ejector rod can conduct the high temperature brought by the laser cutting head, so that the bimetallic strip expands and bends when heated, and the ejector rod moves downward following the bimetallic strip, thereby avoiding the problem that the metal melt adheres to the outer wall during cutting and is difficult to clean.

[0020] 3. When the present invention is in use, the water stored inside the silica gel bag flows upward through the water spray pipe. While cooling the edge of the metal door and window, part of the water can fall into the inner cavity of the ejector rod and continuously flow downward to the top of the bimetallic strip, thereby cooling the bimetallic strip and accelerating its deformation recovery speed, so as to facilitate the reinforcement of the next group of metal doors and windows.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figure 1 - Figure 8, a laser cutting device for metal doors and windows processing, including a lathe 1. A laser cutting head 2 is slidably connected to the top of the lathe 1. A driving structure 3 for driving the movement of the laser cutting head 2 is fixedly installed on the outer wall of the laser cutting head 2. An adjusting structure 4 for adjusting the height of the lathe 1 is fixedly installed at the bottom of the lathe 1. And the height of the lathe 1 is adjusted through the adjusting structure 4 so that the lathe 1 is suitable for other processing equipment, thus facilitating handling and processing. A plurality of ejector rods 5 for supporting the bottom of the metal doors and windows are slidably connected inside the lathe 1. The material of the ejector rod 5 is tungsten, and a fast heat-conducting material is realized by using the material characteristics. An annular blade 8 for removing the metal melt adhered to the outer wall of the ejector rod 5 is fixedly connected to the top of the lathe 1. Since the metal melt just melted and falling on the outer wall of the ejector rod 5 is not fixed on the outer wall of the ejector rod 5 due to its high temperature, when the ejector rod 5 moves down, the annular blade 8 can remove the metal melt adhered to its outer wall. A trigger structure 6 for pushing the ejector rod 5 to move down is fixedly installed at the bottom of the ejector rod 5;

[0033] The trigger structure 6 includes a bimetallic strip 601. The bimetallic strip 601 is fixedly installed in the inner cavity of the lathe 1. The ejector rod 5 is attached to the top of the bimetallic strip 601. A push plate 602 is rotatably connected to the bottom of the bimetallic strip 601. A partition plate 603 is slidably connected to the top of the push plate 602. A pressing plate 604 for pushing the ejector rod 5 to move down is rotatably connected to the top of the partition plate 603. Specifically, a connecting column is fixedly connected to the inner cavity of the pressing plate 604, and the pressing plate 604 is fixedly connected to the outer wall of the ejector rod 5 through the connecting column; The pressing plate 604 is located above the bimetallic strip 601 and is in contact with the bimetallic strip 601. A magnetic block 605 for limiting the pressing plate 604 is installed at one end of the pressing plate 604 away from the ejector rod 5. When the bimetallic strip 601 is heated and bent, the end of the push plate 602 away from the partition plate 603 is pushed down, causing the other end of the push plate 602 to move up, thereby pushing the pressing plate 604 to flip and separate from the magnetic block 605. After the distance between the pressing plate 604 and the magnetic block 605 becomes larger, the magnetic block 605 cannot attract the pressing plate 604. After the pressing plate 604 loses its limit, it uses its own weight and the connecting column to push the ejector rod 5 to move down and retract into the inner cavity of the lathe 1, thus avoiding the metal melt generated during cutting from adhering to the outer wall of the ejector rod 5;

[0034] More specifically, a square groove is opened in the inner cavity of the lathe 1. A first support rod 606 is fixedly connected to the inner cavity of the square groove. The push plate 602 is rotatably sleeved on the outer wall of the first support rod 606. A top plate is fixedly connected to one end of the push plate 602 close to the partition plate 603. When the partition plate 603 rotates, the partition plate 603 can be lifted by the top plate; A second support rod 607 is fixedly connected to the inner cavity of the square groove. The pressing plate 604 is rotatably sleeved on the outer wall of the second support rod 607. A magnetic block 602 for attracting the magnetic block 605 is installed in the inner cavity of one end of the pressing plate 604 close to the magnetic block 605. When the magnetic block 605 and the magnetic block 602 are close to each other and attract each other, the pressing plate 604 is limited to keep it in a horizontal state.

[0035] At the bottom of the trigger structure 6, a water spraying structure 7 for cooling metal doors and windows is installed, and the water spraying structure 7 cools the edges of the metal doors and windows that have just been cut;

[0036] Specifically, when the laser cutting head 2 cuts the doors and windows at the top of any group of ejector rods 5, by using its characteristic of rapid heat conduction, the bimetal sheet 601 is heated and bent downward. When the ejector rod 5 moves downward following it, the water spraying structure 7 is driven to cool the outer wall edges of the metal doors and windows that have just been cut, thereby avoiding the cooling of the metal doors and windows caused by high temperature.

[0037] Please refer to Figure 3 - Figure 4 , the bottom of the ejector rod 5 is threadedly connected with a bottom rod 501, and the bottom rod 501 supports the bottom of the ejector rod 5, thereby facilitating the replacement of the ejector rod 5. Specifically, a threaded column groove 502 is provided in the inner cavity of the ejector rod 5, and a threaded sleeve rod 503 is threadedly connected in the inner cavity of the threaded column groove 502. The bottom of the threaded sleeve rod 503 is fixedly connected to the top of the bottom rod 501. When the ejector rod 5 needs to be replaced, the ejector rod 5 can be rotated to separate the threaded column groove 502 from the threaded sleeve rod 503.

[0038] Please refer to Figure 2 - Figure 3 , at both ends of the bottom of the bimetal sheet 601 and the push plate 602, there are obliquely pushing blocks 619 for pushing the bimetal sheet 601 and the push plate 602 to reset. At one end of the two groups of obliquely pushing blocks 619 close to the bimetal sheet 601 and the push plate 602, there are springs 620 for pushing the obliquely pushing blocks 619 to reset. The obliquely pushing blocks 619 and the springs 620 are fixedly connected through a connecting plate 621. When the push plate 602 flips downward, the two groups of obliquely pushing blocks 619 are pushed to move and the springs 620 are compressed. When the bimetal sheet 601 cools and straightens, the push plate 602 loses the suppression, and the springs 620 push the bimetal sheet 601 and the push plate 602 to reset through the obliquely pushing blocks 619.

[0039] Please refer to Figure 2 and Figure 4, the water spraying structure 7 includes a silica gel bag 701 for storing water. A water spraying pipe 702 is fixedly connected to the top of the silica gel bag 701. At both ends of the outer wall of the silica gel bag 701, clamping shells 703 for extruding the outer wall of the silica gel bag 701 are fixedly connected; specifically, a second spring 704 for pulling the clamping shells 703 to approach each other is fixedly connected between the two groups of clamping shells 703. One end of a group of clamping shells 703 close to the second spring 704 is rotatably connected to a plug rod 705 through a first connecting piece. A support rod 706 is clamped on the outer wall of the plug rod 705. One end of the support rod 706 close to the second spring 704 is rotatably connected to the outer wall of a group of clamping shells 703 through a second connecting piece. A third spring 707 for supporting the support rod 706 is fixedly connected to the bottom of the support rod 706. When a group of clamping shells 703 is slightly extruded and the support rod 706 flips downward, the plug rod 705 flips upward following the shape of the outer wall of the support rod 706, causing the two groups of clamping shells 703 to lose support. Through the pulling of the second spring 704, the two ends of the outer wall of the silica gel bag 701 are extruded, enabling the water stored inside the silica gel bag 701 to flow upward through the water spraying pipe 702 and be sprayed on the edge of the metal door and window for cooling. At the same time, part of the water can fall into the inner cavity of the top rod 5 and continuously flow downward to the top of the bimetallic strip 601, thereby cooling the bimetallic strip 601 and accelerating its deformation recovery speed;

[0040] Above the water spraying pipe 702 and at the top of the top rod 5, a triangular baffle 504 for protecting the top of the water spraying pipe 702 is rotatably connected. A special-shaped block is fixedly connected to the top of the top rod 5, and a shaft rod is fixedly connected inside the special-shaped block. The triangular baffle 504 is rotatably connected to the outer wall of the shaft rod, so that when the top rod 5 moves downward, the triangular baffle 504 fan-shapedly moves and flips open around the shaft rod; a column groove is provided in the inner cavity of the bottom rod 501, and the water spraying pipe 702 is slidably connected to the inner cavities of the top rod 5 and the bottom rod 501. The water spraying pipe 702 penetrates through the outer wall of the bottom rod 501 and is fixedly installed in the inner cavity of the lathe 1, so that when the bottom rod 501 drives the top rod 5 to move downward, the position of the water spraying pipe 702 remains unchanged.

[0041] Multiple groups of pipes are provided between several silica gel bags 701 for connection. A water tank is fixedly installed at the bottom of the lathe 1. The pipes are inserted into the inside of the pipes, and a water pump is installed at the end of the pipes, so that through the water pump, water enters the inside of the silica gel bags 701 through the pipes;

[0042] A connecting pipe 708 is fixedly connected to the bottom of the water spraying pipe 702. The water spraying pipe 702 and the connecting pipe 708 are fixedly connected through a flexible hose. A water baffle 709 is slidably inserted between the water spraying pipe 702 and the connecting pipe 708 at the end far from the flexible hose. When the water baffle 709 slides between the water spraying pipe 702 and the connecting pipe 708, the flexible hose is extruded, so that the water flow inside the connecting pipe 708 cannot pass through the flexible hose and enter the inside of the water spraying pipe 702, but is sprayed upward. When the water baffle 709 moves out between the water spraying pipe 702 and the connecting pipe 708, the water inside the connecting pipe 708 can pass through the flexible hose and enter the water spraying pipe 702 to flow upward and be sprayed.

[0043] Please refer to Figure 2 and Figure 5 - Figure 6 Figure 6 , the trigger structure 6 further includes a special-shaped push block 608, the special-shaped push block 608 is fixedly connected to the outer wall of the ejector rod 5, the bottom of the special-shaped push block 608 is attached to the top of the water baffle 709, so that when the special-shaped push block 608 moves downwards following the ejector rod 5, it pushes the water baffle 709 to move. One end of the special-shaped push block 608 away from the ejector rod 5 is rotatably connected to a sliding rod 609. An annular groove 610 for providing sliding of the sliding rod 609 is opened in the inner cavity of the lathe 1. A third magnet 611 for pushing the sliding rod 609 to move upwards is fixedly connected to the bottom of the annular groove 610. A push rod 612 for pushing the clamping shell 703 to move is slidably sleeved on the outer wall of the sliding rod 609. Specifically, one end of the special-shaped push block 608 close to the push rod 612 is rotatably connected to a first extension rod 613. The first extension rod 613 away from the special-shaped push block 608 is slidably connected to a second extension rod 614. A third extension rod 615 is slidably connected between the first extension rod 613 and the second extension rod 614; a fourth magnet repulsive to the third magnet 611 is fixedly connected to the inner cavity of the sliding rod 609, so that when the sliding rod 609 slides along the inner shape of the annular groove 610 to the bottom of the annular groove 610, the third magnet 611 pushes the sliding rod 609 to move upwards and reset;

[0044] A through groove 616 is opened in the inner cavity of the push rod 612, and the sliding rod 609 is slidably connected to the inner cavity of the through groove 616, so that when the sliding rod 609 slides in the inner cavity of the annular groove 610, it can drive the push rod 612 to move through the through groove 616; one end of the push rod 612 close to the clamping shell 703 is fixedly connected to a moving block 617, so that when the push rod 612 moves, it pushes the moving block 617 to move. Rollers 618 for increasing the flexibility of the moving block 617 are fixedly installed at both ends of the moving block 617. An concave groove for providing sliding of the push rod 612 and the moving block 617 is opened in the inner cavity of the lathe 1.

[0045] Embodiment 2: Please refer to Figure 1 and Figure 7, A laser cutting device for metal door and window processing, which is different from that of Embodiment 1 in that the driving structure 3 includes a first threaded rod 301 for driving the laser cutting head 2 to adjust its height. The first threaded rod 301 is rotatably connected to the top of the lathe 1. A belt 302 for driving the laser cutting head 2 to move is rotatably connected to the side end of the first threaded rod 301. A second threaded rod 303 for driving the laser cutting head 2 to move is rotatably connected to the bottom of the belt 302. Specifically, a bracket for supporting the first threaded rod 301 is fixedly connected to the outer wall of the lathe 1, and a first motor 304 for driving the first threaded rod 301 to rotate is fixedly connected to the bottom of the first threaded rod 301; A driving wheel for driving the belt 302 to rotate is rotatably connected to the inner cavity of the belt 302. A second motor for driving the belt 302 to rotate is fixedly connected to the axis of the driving wheel. A driven wheel is rotatably connected to the inner cavity of the end of the belt 302 away from the driving wheel; A third motor 305 for driving the second threaded rod 303 to rotate is fixedly connected to the side end of the second threaded rod 303.

[0046] Embodiment 3: Please refer to Figure 1 and Figure 8 - Figure 9 , A laser cutting device for metal door and window processing, which is different from that of Embodiment 1 in that the adjusting structure 4 includes a sliding leg 401. The top of the sliding leg 401 is fixedly connected to the bottom of the lathe 1. A fixed leg 402 is slidably connected to the outer wall of the sliding leg 401. A tooth 403 for urgently limiting the sliding leg 401 is rotatably connected to the inner cavity of the fixed leg 402. Specifically, a tooth block 404 is fixedly connected to the inner cavity of the sliding leg 401. The tooth block 404 is meshed with a gear 405. A motor 406 for driving the gear 405 to rotate is fixedly installed on the outer wall of the fixed leg 402;

[0047] More specifically, a grooved rod 407 is fixedly connected to the output shaft of the drive motor 406. A column shaft 408 is slidably connected to the inner cavity of the grooved rod 407. One end of the column shaft 408 away from the grooved rod 407 is fixedly connected to the center of the gear 405. Thus, during the use process, when the motor 406 fails and causes the sliding leg 401 to drive the tooth block 404 to move downward rapidly, it drives the gear 405 to rotate rapidly. When the gear 405 rotates at a high speed, under the influence of centrifugal force and inertial force, it moves into the internal of the engaging tooth 403, causing the engaging tooth 403 to engage with the gear 405, limiting the sliding leg 401, thereby preventing the sliding leg 401 and the lathe 1 from continuously sliding downward and generating a huge impact force. When the sliding leg 401 drives the lathe 1 to collide with the top of the fixed leg 402, the internal parts of the lathe 1 are damaged; a hollow groove is provided in the inner cavity of the fixed leg 402. A rod body 409 is fixedly connected to the inner cavity of the hollow groove. The engaging tooth 403 is rotatably connected to the outer wall of the rod body 409. A fourth spring 410 is also fixedly connected to the inner cavity of the hollow groove. One end of the fourth spring 410 close to the engaging tooth 403 is fixedly connected to the outer wall of the engaging tooth 403, thereby providing a certain rotation space for the engaging tooth 403 to facilitate better docking with the gear 405 and thus engaging the gear 405.

[0048] The working principle of the present invention is as follows: First, drive the motor 406 to push the sliding leg 401 to drive the lathe 1 to move up and down through the gear 405 and the tooth block 404, adjust the height according to requirements, then place the metal door and window on the top of the lathe 1, and respectively drive the first motor 304, the third motor 305 and the second motor to drive the laser cutting head 2 to move on the top of the lathe 1, and cut the metal door and window placed on the top of the lathe 1 as needed;

[0049] When the laser cutting head 2 cuts a part of the metal door and window on the top of a group of top rods 5, the top rods 5 can conduct the high temperature brought by the laser cutting head 2, causing the bimetallic strip 601 to expand and bend downward due to heat, thereby pushing the push plate 602 to move downward. When the push plate 602 moves downward, it pushes the inclined push block 619 to retract, and at the same time pushes the end of the push plate 602 away from the partition plate 603 downward, causing the other end of the push plate 602 to move upward, thereby pushing the pressing plate 604 to flip and separate from the first magnet 605. After the distance between the pressing plate 604 and the first magnet 605 becomes larger, the first magnet 605 cannot attract the pressing plate 604. After the pressing plate 604 loses its limit, it uses its own weight to push the top rod 5 to move further downward through the connecting column, and retracts into the inner cavity of the lathe 1;

[0050] At the same time, when the push rod 5 moves downward, the special-shaped push block 608 can be driven to move downward, so that the special-shaped push block 608 pushes the water baffle 709 to slide out from between the water spray pipe 702 and the connecting pipe 708, and at the same time pushes the special-shaped push block 608 to move toward the end of the push rod 612, and pushes the slide bar 609 to rotate around the inside of the annular groove 610, so that when the slide bar 609 drives the push rod 612 to move toward the end of the moving block 617, the moving block 617 is pushed to squeeze a group of clamp shells 703, so that when a group of clamp shells 703 are squeezed, the support rod 706 flips downward. The plug rod 705 turns upwards following the shape of the outer wall of the support rod 706, so that the two sets of clamp shells 703 lose their support, and the two ends of the outer wall of the silica gel bag 701 are squeezed by the pulling of the spring 2 704, so that the water stored in the silica gel bag 701 flows upwards through the water spray pipe 702 and sprays on the edge of the metal door and window to cool down. At the same time, part of the water can fall into the inner cavity of the top rod 5 and continue to flow downwards to the top of the bimetallic strip 601, thereby cooling the bimetallic strip 601 and accelerating its deformation recovery speed;

[0051] When the bimetallic strip 601 cools down and its bending arc gradually becomes smaller, the spring 1 620 can push the bimetallic strip 601 upward to reset through the oblique push block 619, and at the same time push the push plate 602 to flip and reset, so that the partition 603 squeezes the push plate 602 downward to reset, so that the pressure plate 604 loses its thrust. When the bimetallic strip 601 moves upward, it pushes the pressure plate 604 to flip upward, so that the pressure plate 604 and the magnetic block 1 605 are close to each other, so that the pressure plate 604 and the magnetic block 1 605 attract each other again, so that the pressure plate 604 keeps The connecting rod 705 is in a horizontal state, thereby driving the top rod 5 to reset through the connecting rod; and then driving the water pump to allow the water inside the water tank to enter the inner cavity of the silicone bag 701 through the pipe to prop up the silicone bag 701. When the silicone bag 701 is propped up, a gap will be generated between the two groups of clamp shells 703, so that the spring three 707 pushes the support rod 706 to flip upward, and the insertion rod 705 naturally flips downward, so that the insertion rod 705 is clamped in the inner cavity of the support rod 706 again, limiting the two groups of clamp shells 703, thereby helping to share the pressure of the silicone bag 701.
