Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment, and in particular to a bevel laser cutting machine. Background Technology

[0002] Laser cutting operations generate a large amount of welding slag and dust, which permeate the workshop air. Previously, dust extraction devices were installed on laser cutting machines to address this issue. However, traditional dust extraction devices are mostly located on the side or bottom of the worktable, which is insufficient for large-format laser cutting machines. As the cutting area increases, the dust spreads further, and the cutting location may be far from the dust extraction port. Furthermore, long extraction ducts cause air pressure loss, resulting in relatively low air pressure at the extraction port near the cutting location. This leads to poor extraction efficiency and an inability to effectively remove the pollutants generated during cutting. Utility Model Content

The various technical features in this utility model can be combined interactively without contradicting each other.

[0020] Laser cutting operations generate a large amount of welding slag and dust, which permeate the workshop air. Previously, dust extraction devices were installed on laser cutting machines to address this issue. However, traditional dust extraction devices are mostly located on the side or bottom of the worktable, which is insufficient for large-format laser cutting machines. As the cutting area increases, the dust spreads further, and the cutting location may be far from the dust extraction port. Furthermore, long extraction ducts cause air pressure loss, resulting in relatively low air pressure at the extraction port near the cutting location. This leads to poor extraction efficiency and an inability to effectively remove the pollutants generated during cutting.

[0021] Therefore, this utility model proposes a bevel laser cutting machine, referring to... Figures 1-6It includes a frame 100, a worktable 200, a crossbeam 300, a ventilation assembly 400, a cutting assembly 500, a first drive device 600, and two first guide rails 700. The two first guide rails 700 are arranged parallel to each other on the top sides of the frame 100 and enclose a cutting space. The crossbeam 300 is arranged perpendicular to the first guide rails 700 and slidably connected to them. The first drive device 600 is mounted on the crossbeam 300 and drives the crossbeam 300 to move along the first guide rails 700. The worktable 200 is located within the cutting space and below the crossbeam 300. The cutting assembly 500 is mounted on the crossbeam 100. The top of the beam 300 is slidably connected to the crossbeam 300. The exhaust assembly 400 includes a first exhaust pipe 410, a fan, and multiple cover plate assemblies 430. The first exhaust pipe 410 is fixed to the bottom of the crossbeam 300. The first exhaust pipe 410 is provided with multiple exhaust ports that communicate with the cutting space. The multiple exhaust ports are distributed at intervals along the length direction of the first exhaust pipe 410 and divide the cutting space into multiple exhaust areas. The fan is fixed to the frame 100. The end of the first exhaust pipe 410 is connected to the fan through a pipe. The cover plate assembly 430 covers the exhaust ports one by one and is used to open or close its corresponding exhaust port.

[0022] The frame 100 provides basic support; the worktable 200 holds the workpiece to be cut; the crossbeam 300 supports and carries the cutting assembly 500 and the exhaust assembly 400, and moves along the first guide rail 700 under the drive of the first drive device 600, thereby driving the cutting assembly 500 and the exhaust assembly 400 to work in different positions, expanding the cutting range and the exhaust coverage; the cutting assembly 500 can move along the length of the crossbeam 300 to perform laser cutting on the workpiece on the worktable 200; the end of the first exhaust pipe 410 is connected to the fan through a pipe to transport the collected pollutants to the fan; multiple cover plate assemblies 430 can open or close the corresponding exhaust ports on the first exhaust pipe 410, control the exhaust area according to the actual situation such as the cutting position, enhance the negative pressure effect in the first exhaust pipe 410, and improve the exhaust efficiency. The exhaust assembly 400 moves synchronously with the crossbeam 300 to exhaust and remove dust from the cutting area. The cover plate assembly 430 on the exhaust assembly 400 opens the exhaust port of the corresponding area according to the cutting position, accurately capturing pollutants such as smoke and dust generated at the cutting position, reducing energy consumption while ensuring the exhaust effect.

[0023] During the cutting process, the first drive device 600 drives the crossbeam 300 to move along two parallel first guide rails 700, bringing the cutting assembly 500 to the set cutting start position. The cutting assembly 500 then begins laser cutting the workpiece on the worktable 200. Simultaneously, the exhaust assembly 400 moves synchronously to the cutting position, and the fan in the exhaust assembly 400 generates suction. Through the exhaust port near the cutting area, the smoke and dust generated during cutting are drawn into the first exhaust pipe 410, achieving follow-up exhaust dust removal along the X-axis. When the cutting assembly 500 moves along the length of the crossbeam 300, the cover plate assembly 430 in the corresponding exhaust area opens the corresponding exhaust port, while the cover plate assembly 430 in other exhaust areas closes the exhaust ports. This ensures that only the exhaust port at the cutting position is connected to the cutting space, enhancing the negative pressure effect within the first exhaust pipe 410 and making the dust removal effect more significant, achieving follow-up exhaust dust removal along the Y-axis. The first exhaust duct 410 can be connected to the fan via a flexible corrugated pipe to accommodate the reciprocating movement of the crossbeam 300.

[0024] In one embodiment, the cover assembly 430 includes a second driving device 431, a cover body 432, an exhaust hood 433, and a second guide rail. The exhaust hood 433 covers the exhaust ports one by one. The top, bottom, and side facing the cutting space of the exhaust hood 433 are provided with a plurality of first air ports 435. The second guide rail is arranged on the exhaust hood 433 along the length direction of the crossbeam 300. The cover body 432 is slidably connected to the second guide rail. The cover body 432 is provided with a plurality of second air ports 436 that match the first air ports 435. The second driving device 431 is arranged on the exhaust hood 433. The output end of the second driving device 431 is connected to the cover body 432 to drive the cover body 432 to move along the second guide rail, so that the first air ports 435 and the second air ports 436 are misaligned or aligned. The cover plate body 432 is driven by the second drive device 431 to move along the second guide rail, thereby switching between the misaligned or aligned states of the first air port 435 and the second air port 436. This controls the opening and closing degree of the exhaust port and the size of the ventilation area. The exhaust can be flexibly adjusted according to the actual cutting position and the amount of smoke and dust generated, thereby improving the accuracy of dust extraction. The state of the air port can be adjusted as needed to make the exhaust process more in line with the actual cutting process, avoiding ineffective or insufficient exhaust, optimizing the airflow direction, and effectively enhancing the exhaust efficiency. Specifically, the second drive device 431 is a cylinder.

[0025] When the cover plate body 432 moves, it may sway or deviate due to external forces, resulting in directional deviation. Therefore, in one embodiment, the cover plate assembly 430 further includes a guide plate 437. The guide plate 437 is disposed on the exhaust hood 433 along the length direction of the crossbeam 300. The guide plate 437 and the exhaust hood 433 enclose each other on the side facing the cutting space to form a second guide rail. The guide plate 437 is disposed on the exhaust hood 433 along the length direction of the crossbeam 300 and together with the exhaust hood 433 to form a second guide rail, providing a guiding path for the movement of the cover plate body 432. Through the cooperation of the guide plate 437 and the exhaust hood 433, the force exerted on the cover plate body 432 during the movement is better borne, reducing swaying and deviation, and ensuring the stability of the movement of the cover plate body 432.

[0026] The weight of the crossbeam 300 and the components mounted thereon may cause insufficient power or transmission jamming during the movement of the first drive device 600. Therefore, in one embodiment, the first drive device 600 includes a first motor 610, a first gear, and a first rack 630. The first rack 630 is mounted on the frame 100 and parallel to the first guide rail 700. The first motor 610 is fixed to the crossbeam 300. The first gear is coaxially rotatable with the output of the first motor 610, and meshes with the first rack 630. The first motor 610 drives the first gear to rotate, and through the meshing of the gear and rack, the rotational motion is converted into linear motion of the crossbeam 300 along the direction of the first guide rail 700, allowing the crossbeam 300 to be positioned at the desired cutting position. The gear and rack transmission can withstand relatively large loads, effectively supporting the weight of the crossbeam 300 and components such as the cutting assembly 500 and the exhaust assembly 400 mounted on the crossbeam 300, while maintaining stable transmission efficiency and motion during the movement of these components.

[0027] During frequent movement of the crossbeam 300, the rigidly connected ductwork will be subjected to significant tensile forces, easily leading to duct breakage, interface detachment, and other damage. Therefore, in one embodiment, the exhaust assembly 400 further includes a second exhaust pipe 440 and an exhaust box 450. The exhaust box 450 is fixed to one end of the crossbeam 300. The end of the first exhaust pipe 410 is connected to the second exhaust pipe 440 through the exhaust box 450. The exhaust box 450 is slidably connected to the second exhaust pipe 440, and one end of the second exhaust pipe 440 is connected to the air inlet of the fan. The exhaust box 450 connects the first exhaust pipe 410 and the second exhaust pipe 440 and can slide on the second exhaust pipe 440, ensuring that the connectivity between the various parts of the exhaust assembly 400 is not affected when it moves with the crossbeam 300, adapting to the exhaust needs of different locations; avoiding damage to the ductwork caused by tensile forces during the movement of the crossbeam 300, and maintaining the structural stability of the exhaust system.

[0028] During the movement of the exhaust box 450 along with the crossbeam 300, the connection between the second exhaust pipe 440 and the exhaust box 450 may be interrupted, resulting in the dust generated in the cutting area not being extracted in time. Therefore, in one embodiment, the exhaust box 450 includes a box body 451, a pressure belt 452, two upper rollers 453 and two lower rollers 454. The side of the box body 451 is provided with a first opening connected to the first exhaust pipe 410, the bottom surface of the box body 451 is provided with a second opening, the top of the second exhaust pipe 440 is provided with a third opening, the two ends of the pressure belt 452 are respectively fixed to the two ends of the second exhaust pipe 440 and cover the third opening, the two upper rollers 453 are provided at the two ends of the inner top of the box body 451, and the two lower rollers 454 are provided at the two ends of the inner bottom of the box body 451. The pressure belt 452 passes around the lower rollers 454 and the upper rollers 453 in sequence so that the second opening and the third opening remain connected during movement. By passing the pressure belt 452 sequentially around the lower roller 454 and the upper roller 453, the second opening and the third opening can always remain connected during the relative movement of the exhaust box 450 and the second exhaust pipe 440, ensuring smooth airflow transmission within the exhaust assembly 400. The pressure belt 452 covers the third opening and fits tightly under the action of the roller, enhancing the sealing of the connection, preventing air leakage during exhaust, maintaining a negative pressure environment within the exhaust pipe, and improving exhaust efficiency.

[0029] Preferably, the exhaust box 450 further includes at least two sets of pulleys 455. The two sets of pulleys 455 are respectively disposed on the front and rear side walls of the box body 451 along the moving direction of the first guide rail 700. The wheel surface of the pulley 455 abuts against the outer surface of the pressure belt 452, so that the pressure belt 452 is tightly pressed against the top surface of the second exhaust pipe 440. By providing pulleys 455 on the front and rear side walls of the exhaust box 450, and making their wheel surfaces abut against the outer surface of the pressure belt 452, the pressure belt 452 can be pressed more tightly against the top surface of the second exhaust pipe 440, enhancing the sealing effect. The pulleys 455 play an auxiliary supporting and constraining role for the pressure belt 452, enabling the pressure belt 452 to maintain appropriate tension and shape during movement.

[0030] When cutting complex-shaped workpieces, it may be impossible to cut along curved or irregular paths, resulting in workpieces that do not meet processing requirements. Therefore, in one embodiment, the cutting assembly 500 includes a cutting head 510, a third driving device 520, a moving seat 530, and a fourth driving device 540. The moving seat 530 is disposed on the top of the crossbeam 300 and slidably connected to the crossbeam 300. The third driving device 520 is disposed on the moving seat 530 and drives the moving seat 530 to move along the length direction of the crossbeam 300. The fourth driving device 540 is disposed on the moving seat 530, and the cutting head 510 is disposed on the driving part of the fourth driving device 540. The fourth driving device 540 is used to drive the cutting head 510 to move vertically. The third drive device 520 drives the moving base 530 to move along the length of the crossbeam 300, and the fourth drive device 540 drives the cutting head 510 to move vertically. The cutting head 510 can flexibly adjust its position in a two-dimensional plane, easily meeting the cutting needs of workpieces of different shapes and sizes, improving the cutting flexibility and applicability of the laser cutting equipment; the position and height of the cutting head 510 can be quickly adjusted according to the cutting task, improving work efficiency. Specifically, the third drive device 520 is a combination of a motor and a gear and rack mechanism, and the fourth drive device 540 is a combination of a motor and a ball screw mechanism.

[0031] When beveling is required, it may be difficult to quickly and accurately switch the angle of the cutting head 510. Therefore, in one embodiment, the cutting assembly 500 further includes an X-axis rotary platform 550 and a Y-axis rotary platform 560. The X-axis rotary platform 550 is mounted on the drive unit of the fourth drive device 540, the Y-axis rotary platform 560 is mounted on the drive unit of the X-axis rotary platform 550, and the cutting head 510 is mounted on the drive unit of the Y-axis rotary platform 560. The rotation axis of the X-axis rotary platform 550 is parallel to the length direction of the first guide rail 700, and the rotation axis of the Y-axis rotary platform 560 is perpendicular to the rotation axis of the X-axis rotary platform 550. By flexibly adjusting the angle of the cutting head 510 through the X-axis rotary platform 550 and the Y-axis rotary platform 560, the cutting head 510 can be driven to rotate to form various bevel angles, thus broadening the processing function of the equipment and improving its applicability. Controlling the rotation angle of the cutting head 510 ensures the accuracy of the bevel angle, making the bevel cutting surface flatter and smoother, with higher dimensional accuracy, improving the cutting quality of the workpiece, and reducing errors caused by the bevel angle.

[0032] The exhaust system 400 may not be able to collect all pollutants in a timely manner, and some smoke and dust may permeate the workshop. Therefore, in one embodiment, the bevel laser cutting machine further includes a dust removal chamber 800 and a support base 810. The dust removal chamber 800 is fixedly connected to the crossbeam 300 and moves synchronously with the crossbeam 300 along the first guide rail 700. The dust removal chamber 800 surrounds the cutting space to form a closed cutting working cavity. The support base 810 is located at the bottom of the crossbeam 300 and is slidably connected to the first guide rail 700 by a slider. The dust removal chamber 800 is enclosed outside the cutting space to form a closed cutting operation cavity, reducing the spread of pollutants such as smoke and dust generated during cutting to other areas of the workshop. It works in conjunction with the exhaust fan 400 to better remove smoke and dust, effectively improving the air quality of the workshop and creating a healthier working environment for operators. The dust removal chamber 800 moves synchronously along the first guide rail 700 with the crossbeam 300. No matter where the cutting head 510 moves to for cutting, it can always maintain the closed nature of the cutting operation cavity, ensuring that the cutting process is in a relatively stable and clean environment, reducing the impact of external factors such as airflow disturbances on laser cutting.

[0033] Irregularly shaped scrap space may not be fully utilized, leading to waste and increased material costs. Therefore, in one embodiment, the beveling laser cutting machine further includes a scanning component, which includes a control system, a camera 900, and a contour scanner 910. The camera 900 is fixed on the movable base 530 and faces the cutting space, while the contour scanner 910 is fixed on the drive unit of the fourth drive device 540 and moves synchronously with the cutting head 510. Both the camera 900 and the contour scanner 910 are electrically connected to the control system. The camera 900 performs an initial positioning search on the scrap material on the worktable 200. After the search is completed, the scrap material contour is input into the operating system interface. After confirming the graphic, the contour scanner 910 on the right side of the cutting head 510 performs a second precise scan and height confirmation. After the scan is completed, the cutting pattern is automatically laid out within the scrap material contour, and cutting is started, which is beneficial for the utilization of the scrap material.
