Description

Technical Field

[0001] This invention belongs to the field of door and window processing technology, specifically relating to a laser cutting device for the production and processing of aluminum alloy doors and windows. Background Technology

[0002] Laser cutting technology in aluminum alloy door and window production utilizes a high-energy-density laser beam to perform non-contact, rapid cutting of aluminum profiles. Compared to traditional sawing, it offers advantages such as high cutting precision, smooth, burr-free cut surfaces, and a small heat-affected zone. It effectively prevents profile deformation and supports complex pattern processing, significantly improving the accuracy of door and window corner assembly and production efficiency.

[0003] Patent CN120244281A discloses a laser cutting device for the production and processing of aluminum alloy doors and windows, which relates to the field of aluminum alloy door and window production technology. The device includes a worktable, a hydraulic cylinder and a laser cutter, and a mounting bracket is provided on the top of the worktable. This invention enables the side wall clamping mechanism and the top wall clamping mechanism to work together. Through the linkage of the connecting plate with the side frame and the movable frame, when the multi-stage telescopic rod extends, the movable frame moves to the right and drives the side frame to move in the opposite direction, precisely clamping the workpiece side wall. During this process, the workpiece pushes the inclined pusher to slide outward, causing the inclined pusher to move upward. Its upward force causes the rotating plate to deflect around the pin shaft, driving the top plate to descend and press tightly against the top wall of the workpiece, completing dual positioning. The electric push rod drives the support frame to move horizontally, and through the sliding connection between the limit sleeve and the limit rod, the top plate flexibly adapts to workpieces of different thicknesses without manual intervention, significantly improving overall production efficiency and ensuring the continuity and high precision of the cutting operation. It achieves automated workpiece clamping and processing. Although this device solves the aforementioned problems, there is still a significant fixing force required when fixing aluminum workpieces during use, which can easily lead to workpiece deformation and processing failure. Summary of the Invention

[0004] The purpose of this invention is to provide a laser cutting device for the production and processing of aluminum alloy doors and windows, so as to solve the problem that when fixing aluminum workpieces, the large fixing force can easily cause the workpieces to deform and be damaged.

[0005] To achieve the above objectives, the present invention provides a laser cutting device for the production and processing of aluminum alloy doors and windows, including a base frame, a protective shell fixedly connected to the top of the base frame, an operating table provided on the outer wall of the base frame, a soft fixing mechanism provided inside the base frame, a slag collection mechanism provided inside the base frame, a pre-treatment mechanism provided inside the base frame, and a feed port rotatably connected to the outer wall of the base frame. The soft-fixing mechanism includes a vertical slide, a lifting plate, a pull frame, a horizontal groove, and a vertical base plate. The vertical slide is slidably connected to the inner wall of the base frame, the lifting plate is fixedly connected to the top of the vertical slide, the pull frame is fixedly connected to the outer wall of the lifting plate, the horizontal groove is opened on the outer wall of the lifting plate, and the vertical base plate is fixedly connected to the bottom of the lifting plate. The vertical base plate is fixedly connected to the vertical slide.

[0006] In one possible implementation, the soft-fixing mechanism further includes a bidirectional screw, a C-shaped guide, a top horizontal plate, a bottom fixed plate, and a horizontal sliding limiter. The bidirectional screw is rotatably connected to the inner wall of the vertical base plate. A motor is provided on the left side of the bidirectional screw, and the bidirectional screw is fixedly connected to the output end of the motor. The C-shaped guide is movably connected to the outer circumferential surface of the bidirectional screw. A locking key is provided on the inner wall of the C-shaped guide, and the locking key is located in the helical groove on the circumferential surface of the bidirectional screw. The top horizontal plate is fixedly connected to the top of the C-shaped guide. The C-shaped guide is slidably connected to the bottom of the lifting plate. The C-shaped guide is slidably connected to the horizontal groove. The top horizontal plate is slidably connected to the lifting plate. The bottom fixed plate is fixedly connected to the outer wall of the top horizontal plate. The horizontal sliding limiter is slidably connected to the inner wall of the top horizontal plate.

[0007] In one possible implementation, the flexible fixing mechanism further includes a flexible rod, a fixed block, and a stop button. The flexible rod is fixedly connected to the outer wall of the transverse sliding frame, the fixed block is fixedly connected to the inner wall of the flexible rod, and the stop button is fixedly connected to the outer wall of the top transverse plate. The stop button is electrically connected to the motor and is located on the movement trajectory of the fixed block.

[0008] In one possible implementation, the slag collection mechanism includes a partition plate, a handle, a limiting plate, and a horizontal frame. The partition plate is slidably connected to the inner wall of the base frame, the handle is fixedly connected to the outer wall of the partition plate, the limiting plate is fixedly connected to the inner wall of the base frame, the partition plate is slidably connected to the top horizontal plate, and the horizontal frame is fixedly connected to the outer wall of the lifting plate. Before loading, the device pulls the frame to move the lifting plate. After the lifting plate moves to the outside of the base frame, it is convenient for workers to load and unload the device, avoiding the safety hazard caused by workers putting half of their bodies into the base frame.

[0009] In one possible implementation, the slag collection mechanism further includes a flexible tube, an air chamber, and an outlet. The flexible tube is fixedly connected to the outer wall of the horizontal frame and is slidably connected to the limiting plate. The air chamber is fixedly connected to the top of the limiting plate, and the outlet is fixedly connected to the bottom of the air chamber. The air chamber and the flexible tube are fixedly connected.

[0010] In one possible implementation, the slag collection mechanism includes a slag bin, a grating plate, and a sliding box. The slag bin is fixedly connected to the inner wall of the base frame, the grating plate is opened at the top of the slag bin, and the sliding box is slidably connected to the inner wall of the slag bin. The gas exits through the outlet at the bottom of the air chamber. The gas exiting through the outlet blows across the surface of the workpiece, removing the cutting slag from the surface of the workpiece as it is removed from the device. After the cutting slag is removed, it is guided by the airflow to fall into the interior of the slide box for collection, facilitating the unified processing of the cutting slag by the workers.

[0011] In one possible implementation, the pretreatment mechanism includes a helical rod, a vertical frame, and a horizontal rotating frame. The helical rod is rotatably connected to the inner wall of the base frame, the vertical frame is fixedly connected to the inner wall of the air chamber, and the horizontal rotating frame is rotatably connected to the outer wall of the air chamber. The vertical frame and the helical rod are rotatably connected, and the vertical frame and the horizontal rotating frame are connected by a bevel gear set. The horizontal frame is movably connected to the helical rod, and the inner wall of the horizontal frame is provided with a locking key, which is located in a helical groove on the surface of the helical rod.

[0012] In one possible implementation, the pretreatment mechanism includes a brush and a guide rod. The brush is fixedly connected to the outer circumferential surface of the horizontal rotating frame rod, and the guide rod is rotatably connected to the inner wall of the base frame. The guide rod and the spiral rod are connected by a pulley set for transmission.

[0013] In one possible implementation, the pretreatment mechanism further includes a short guide rod and a grinding disc. The short guide rod is rotatably connected to the inner wall of the base, the inner wall of the grinding disc is in contact with the circumferential surface of the guide rod, the short guide rod is in contact with the inner wall of the grinding disc, the grinding disc is located on the movement trajectory of the processed material, and the brush is located on the movement trajectory of the sheet metal. The rotating guide rod drives the grinding disc to rotate, and the rotating grinding disc performs preliminary grinding and removal of burrs on the surface of the cut opening of the workpiece at the bottom, saving the time of subsequent manual grinding of the finished part, thereby improving the production efficiency of the product.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, with the cooperation of the solid block, the stop button, and the flexible rod, the flexible rod moves the solid block during its movement. The solid block moves and contacts the stop button, which then stops the motor by pressing, causing the top horizontal plate to move. At this time, the flexible rod clamps the aluminum alloy material laterally. When the solid block contacts the stop button, the flexible rod also stops moving, thus avoiding excessive pressure from the flexible rod on the aluminum alloy sheet, which could cause deformation and errors in subsequent processing.

[0015] 2. In this invention, with the cooperation of the flexible mounting tube, the lifting plate, and the air chamber, after the workpiece is processed, the lifting plate moves out of the device. During the movement of the lifting plate, the horizontal frame moves under the limitation of the limiting plate. During the movement of the horizontal frame, the flexible mounting tube is squeezed and shrinks. After the flexible mounting tube shrinks, the gas inside will enter the air chamber and be discharged from the outlet at the bottom of the air chamber. The gas discharged from the outlet will blow on the surface of the workpiece, so that the cutting slag on the surface of the workpiece is blown away during the removal of the workpiece from the device.

[0016] 3. In this invention, with the cooperation of the horizontal rotating frame, grinding disc, and guide rod, the horizontal rotating frame drives the sweeping brush to move during rotation. The sweeping brush contacts the workpiece at the bottom during rotation, and the airflow from the outlet sweeps away the cutting slag on the surface of the workpiece, causing it to fall into the sliding box, thus improving the device's processing effect on cutting slag. During rotation, the spiral rod drives the guide rod to rotate through the pulley set. The rotation of the guide rod drives the grinding disc to rotate, and the rotation of the grinding disc performs preliminary grinding and removal of burrs on the surface of the cut edge of the workpiece at the bottom, saving the subsequent manual grinding time of the finished parts, thereby improving the production efficiency of the product.

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figure 1 - Figure 8 As shown, one embodiment of the present invention is: a laser cutting device for the production and processing of aluminum alloy doors and windows, including a base 1, a protective shell 2 fixedly connected to the top of the base 1, a control panel 3 provided on the outer wall of the base 1, a soft fixing mechanism 4 provided inside the base 1, a slag collection mechanism 5 provided inside the base 1, a pre-treatment mechanism 6 provided inside the base 1, and a feed inlet 7 rotatably connected to the outer wall of the base 1; The soft mounting mechanism 4 includes a vertical slide 401, a lifting plate 402, a pull bracket 403, a horizontal groove 404, and a vertical base plate 405. The vertical slide 401 is slidably connected to the inner wall of the base 1. The lifting plate 402 is fixedly connected to the top of the vertical slide 401. The pull bracket 403 is fixedly connected to the outer wall of the lifting plate 402. The horizontal groove 404 is opened on the outer wall of the lifting plate 402. The vertical base plate 405 is fixedly connected to the bottom of the lifting plate 402. The vertical base plate 405 is fixedly connected to the vertical slide 401.

[0021] The soft-fixed mechanism 4 also includes a bidirectional screw 406, a C-shaped guide 407, a top horizontal plate 408, a bottom fixed plate 409, and a horizontal sliding limiter 410. The bidirectional screw 406 is rotatably connected to the inner wall of the vertical base plate 405. A motor is installed on the left side of the bidirectional screw 406, and the bidirectional screw 406 is fixedly connected to the output end of the motor. The C-shaped guide 407 is movably connected to the outer circumferential surface of the bidirectional screw 406, and a locking key is provided on the inner wall of the C-shaped guide 407. Located within the spiral groove on the circumferential surface of the bidirectional screw 406, the top horizontal plate 408 is fixedly connected to the top of the C-shaped guide 407. The C-shaped guide 407 is slidably connected to the bottom of the lifting plate 402. The C-shaped guide 407 is slidably connected to the horizontal groove 404. The top horizontal plate 408 is slidably connected to the lifting plate 402. The bottom fixed plate 409 is fixedly connected to the outer wall of the top horizontal plate 408. The horizontal sliding limit frame 410 is slidably connected to the inner wall of the top horizontal plate 408.

[0022] The soft-fixed mechanism 4 also includes a soft rod 411, a fixed block 412, and a stop button 413. The soft rod 411 is fixedly connected to the outer wall of the horizontal sliding limit frame 410, the fixed block 412 is fixedly connected to the inner wall of the soft rod 411, and the stop button 413 is fixedly connected to the outer wall of the top horizontal plate 408. The stop button 413 is electrically connected to the motor and is located on the movement trajectory of the fixed block 412. When the fixed block 412 contacts the stop button 413, the flexible rod 411 also stops moving, so as to avoid the flexible rod 411 from excessively squeezing the aluminum alloy sheet, causing deformation of the aluminum alloy sheet and resulting in errors in subsequent processing.

[0023] The slag collection mechanism 5 includes a partition plate 501, a handle 502, a limiting plate 503, and a horizontal frame 504. The partition plate 501 is slidably connected to the inner wall of the base frame 1, the handle 502 is fixedly connected to the outer wall of the partition plate 501, the limiting plate 503 is fixedly connected to the inner wall of the base frame 1, the partition plate 501 is slidably connected to the top horizontal plate 408, and the horizontal frame 504 is fixedly connected to the outer wall of the lifting plate 402.

[0024] The slag collection mechanism 5 also includes a flexible tube 505, an air chamber 506, and an outlet 507. The flexible tube 505 is fixedly connected to the outer wall of the horizontal frame 504 and is slidably connected to the limiting plate 503. The air chamber 506 is fixedly connected to the top of the limiting plate 503 and the outlet 507 is fixedly connected to the bottom of the air chamber 506. The air chamber 506 and the flexible tube 505 are fixedly connected.

[0025] The slag collection mechanism 5 includes a slag bin 508, a grating plate 509, and a sliding box 510. The slag bin 508 is fixedly connected to the inner wall of the base frame 1, the grating plate 509 is opened on the top of the slag bin 508, and the sliding box 510 is slidably connected to the inner wall of the slag bin 508. During the movement of the horizontal frame 504, the flexible tube 505 is squeezed and contracted. After the flexible tube 505 contracts, the gas inside will enter the air chamber 506 and be discharged from the outlet 507 at the bottom of the air chamber 506. The gas discharged from the outlet 507 will blow on the surface of the workpiece, so that the cutting slag on the surface of the workpiece will be blown away during the removal of the device.

[0026] Working principle: Before use, the workpiece to be cut is placed on top of the bottom fixed plate 409. Then, the motor is started to drive the bidirectional screw 406 to rotate. The rotation of the bidirectional screw 406 drives the C-shaped guide 407 to move under the limit of the lifting plate 402 through the spiral groove on the circumferential surface. During the movement of the C-shaped guide 407, the top horizontal plate 408 is moved. During the movement of the top horizontal plate 408, the bottom fixed plate 409 is moved. The movement of the bottom fixed plate 409 causes the flexible rod 411 to come into contact with the material to be processed. This, in turn, pushes the flexible rod 411 to move in the opposite direction. During the movement, the flexible rod 411 drives the fixed block 412 to move, which in turn pushes the flexible rod 411 to move the transverse sliding limit frame 410 and compress the spring. After the subsequent workpiece is discharged, the compressed spring can drive the flexible rod 411 and the transverse sliding limit frame 410 to reset, making it convenient for the next use. The fixed block 412 moves and contacts the stop button 413. Then, the stop button 413 is triggered by squeezing and sends an electrical signal to the motor. After receiving the electrical signal, the motor will shut down and stop driving the top transverse plate 408 to move.

[0027] At this time, the flexible rod 411 clamps the aluminum alloy material laterally. When the fixed block 412 contacts the stop button 413, the flexible rod 411 also stops moving to avoid the flexible rod 411 excessively squeezing the aluminum alloy sheet, causing deformation of the aluminum alloy sheet and resulting in errors in subsequent processing. Before loading, the device pulls the pull frame 403 to drive the lifting plate 402 to move. After the lifting plate 402 moves to the outside of the base frame 1, it is convenient for workers to load and unload the device, avoiding the safety hazard caused by workers half-peeping into the inside of the base frame 1.

[0028] During the processing, the isolation plate 501 is located at the bottom of the workpiece. When the laser passes through the workpiece, it is blocked by the isolation plate 501 to prevent the laser beam from being too strong and causing damage to the main body of the device other than the workpiece, thus preventing damage to the device. After the workpiece is processed, a special hook is used to hook the pull frame 403 and then the lifting plate 402 is moved out of the device. (If the cost is sufficient, a set of electric slide rails can be installed at the bottom of the vertical slide frame 401 to enable automatic material discharge without the need for manual tools to hook the pull frame 403.) During the movement of the lifting plate 402, the horizontal frame 504 moves under the limitation of the limiting plate 503. During the movement, the horizontal frame 504 squeezes the flexible tube 505, causing the flexible tube 505 to contract. After the flexible tube 505 contracts, the gas inside will enter the air chamber 506 and then be discharged from the only outlet 507 at the bottom of the air chamber 506. The gas discharged from the outlet 507 will blow on the surface of the workpiece, so that the surface of the workpiece is cooled during the removal of the device, thus preventing the workers from being burned during the subsequent handling of the sheet metal.

[0029] like Figure 1 - Figure 8 As shown, in another embodiment of the present invention based on the above embodiments, the pretreatment mechanism 6 includes a spiral rod 601, a vertical frame 602, and a horizontal rotating frame rod 603. The spiral rod 601 is rotatably connected to the inner wall of the base 1, the vertical frame 602 is fixedly connected to the inner wall of the air chamber 506, and the horizontal rotating frame rod 603 is rotatably connected to the outer wall of the air chamber 506. The vertical frame 602 and the spiral rod 601 are rotatably connected, and the vertical frame 602 and the horizontal rotating frame rod 603 are connected by a bevel gear set. The horizontal frame 504 is movably connected to the spiral rod 601, and the inner wall of the horizontal frame 504 is provided with a locking key, which is located in the spiral groove on the surface of the spiral rod 601.

[0030] The pretreatment mechanism 6 includes a brush 604 and a guide rod 605. The brush 604 is fixedly connected to the outer circumferential surface of the horizontal rotating frame rod 603, and the guide rod 605 is rotatably connected to the inner wall of the base 1. The guide rod 605 and the spiral rod 601 are connected by a belt pulley group for transmission.

[0031] The pretreatment mechanism 6 also includes a short guide rod 606 and a grinding disc 607. The short guide rod 606 is rotatably connected to the inner wall of the base 1. The inner wall of the grinding disc 607 is in contact with the circumferential surface of the guide rod 605. The short guide rod 606 is in contact with the inner wall of the grinding disc 607. The grinding disc 607 is located on the movement trajectory of the processed material, and the brush 604 is located on the movement trajectory of the sheet metal. During the rotation of the spiral rod 601, the guide rod 605 is driven to rotate through the pulley assembly. The rotation of the guide rod 605 drives the grinding disc 607 to rotate. The rotating grinding disc 607 performs preliminary grinding and removal of burrs on the surface of the cut opening of the workpiece, saving the subsequent manual grinding time of the finished part and thus improving the production efficiency of the product.

[0032] Working principle: During the movement of the lifting plate 402, the horizontal frame 504 is moved. The horizontal frame 504, through its internal locking mechanism, drives the spiral rod 601 to rotate. The spiral rod 601, in turn, drives the horizontal rotating frame rod 603 to rotate via a bevel gear set. The horizontal rotating frame rod 603, in turn, drives the sweeping brush 604 to move. During its rotation, the sweeping brush 604 contacts the workpiece at the bottom, removing cutting slag from the workpiece surface and causing it to fall into the sliding box 510, thus improving the device's ability to handle cutting slag. During the rotation of the spiral rod 601, the guide rod 605 is driven to rotate via a pulley set. The rotation of the guide rod 605 drives the grinding disc 607 to rotate. The grinding disc 607 performs preliminary grinding and removal of burrs on the cut surface of the workpiece at the bottom, saving subsequent manual grinding time on the finished parts and thus improving production efficiency.
