Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting machine for manufacturing profiles for metal casement window frames. Background Technology

[0002] In the modern metal door and window manufacturing industry, profile laser cutting machines have become the main equipment for processing aluminum alloy, thermally broken aluminum and other casement window frame profiles. The laser laser machine transmits and focuses the high-energy beam generated by the laser generator through an optical system to form a tiny spot with extremely high power density. This spot is then irradiated onto a predetermined area on the surface of the profile. The irradiated metal material absorbs a large amount of light energy in a short time, and its temperature rises sharply to the melting point or even the boiling point, thus melting or vaporizing. With the relative movement between the beam and the workpiece, the profile is finally cut.

[0003] In the specific processing, the long strip of aluminum alloy or thermally broken aluminum profile is first horizontally clamped on the worktable of the laser cutting machine. A section of the profile body is reserved as the first processing section. Driven by the CNC system, the cutting head completes the feature processing required for the outer frame of the door and window in this suspended area according to the pre-prepared drawings. After the required contour of the area is cut, the servo-driven feeding mechanism pushes the profile along the axis to the next station, and the cutting head begins to perform the same cycle operation on the new area.

[0004] However, in the aforementioned laser cutting process, when laser cutting high-reflectivity and high-thermal-conductivity metal profiles such as aluminum alloys and thermally broken aluminum, the interaction between the laser beam and the metal material causes the metal to melt, generating a large number of dispersed metal fragments. Under the dynamic changes of the molten pool and the disturbance of gas turbulence, the metal fragments exhibit an irregular high-speed splashing state. Among them, the high-temperature, low-viscosity molten droplets are prone to impact and adhere to the cut surface. After condensation, they not only form microscopic nodular protrusions but also are accompanied by oxide layer inclusions, damaging the smoothness and finish of the cut surface. Another part of the medium-temperature metal fragments are scattered on the surface of the profile, thus forming scars. The protrusions on the cut surface, oxide layer inclusions, and scars on the profile surface will lead to insufficient contact between the coating and the profile substrate in the subsequent spraying process, resulting in a decrease in coating adhesion. In subsequent use, coating blistering, peeling, and other failure problems are likely to occur, and appearance defects such as coating color difference and pinholes will also occur. Summary of the Invention

[0005] The purpose of this invention is to provide a profile laser cutting machine for manufacturing metal casement window frames, so as to solve the problem mentioned in the background art of metal spatter affecting the quality of the cut surface and the surface of the profile during the laser cutting process.

[0006] The present invention provides a laser cutting machine for manufacturing metal casement window outer frames, which adopts the following technical solution: A profile laser cutting machine for manufacturing metal casement window frames includes a base frame, a bracket on the base frame, a tooling fixture on the bracket for clamping and conveying profiles, and a laser cutting device on the base frame. The laser cutting device includes a frame, a laser cutting head, and X-axis guide rails, Y-axis guide rails, and Z-axis guide rails on the frame for driving the laser cutting head to move. It also includes a dustproof component and multiple sets of adsorption components. The dustproof assembly includes a cover covering the profile processing area, side plates symmetrically fixed to both sides of the cover, and a mounting bracket connecting the side plates and the bracket. The top of the cover has a channel for the laser cutting head to pass through. Two sets of elastic sealing covers are symmetrically arranged in the channel. A guide kit is slidably connected between the two sets of elastic sealing covers. The laser cutting head can be moved through the guide kit. Multiple sets of the adsorption components are equidistantly distributed along the length of the cover. Each set of adsorption components includes an adsorption nozzle fixed inside the cover and an openable cover plate. The cover plate is used to seal the adsorption nozzle port in the non-processing area. When the laser cutting head moves, it can drive the cover plate of the corresponding processing area to open and close. After the laser cutting head leaves, the cover plate resets and seals.

[0007] Furthermore, it also includes a negative pressure tube assembly, a negative pressure device, and a controller. The negative pressure device provides negative pressure adsorption power to the adsorption nozzle through the negative pressure tube assembly, and the negative pressure device is electrically connected to the controller.

[0008] Furthermore, a gap is provided between the two sets of elastic sealing covers to allow the guide kit to slide.

[0009] Furthermore, each set of elastic sealing covers includes a grooved section, a vertical section symmetrically arranged on the grooved section, a corrugated section connected to the vertical section, and a horizontal section connected to the corrugated section, with the horizontal section fixed to the inner wall of the channel. The guide assembly includes a hollow sleeve block, a protrusion fixed on the hollow sleeve block, and a conical cover fixed to the bottom of the hollow sleeve block, wherein the hollow sleeve block slides in contact with the vertical section, and the protrusion slides in contact with the groove section.

[0010] Furthermore, multiple sets of telescopic components are equidistantly arranged between the channel and the vertical section along the length direction. Each set of telescopic components includes a sleeve hinged to the side wall of the channel, a rod movably inserted into the sleeve, and a first spring set on the rod. The end of the rod away from the sleeve is hinged to the vertical section.

[0011] Furthermore, the adsorption assembly also includes a shaft fixed to the cover plate, a support seat that rotates with the shaft, a gear fixed to the shaft, a rack meshing with the gear, a conical trigger block fixed to the top of the rack, and a trigger plate fixed to the guide assembly. The trigger plate and the conical trigger block are both inclined surfaces. The rack slides through the support seat, and when the trigger plate slides with the guide assembly, it can sequentially abut against the conical trigger block to control the rotation and opening of the cover plate.

[0012] Furthermore, a second spring is provided on the rack, with its two ends fixed to the conical trigger block and the support base, respectively.

[0013] Furthermore, each end of the shaft is provided with a first torsion spring, and the two ends of the first torsion spring are respectively fixed to the cover plate and the support base.

[0014] Furthermore, a ball bearing is movably provided at the top of the conical trigger block, and the ball bearing slides in contact with the bottom of the trigger plate.

[0015] Furthermore, sealing components are symmetrically provided at both ends of the cover. The sealing components include four sets of mounting seats distributed circumferentially along the edge of the cover port. Each set of mounting seats is hinged to a flap for fitting the surface of the profile via a rotating shaft. A second torsion spring is provided on the rotating shaft. The two ends of the second torsion spring are fixed to the mounting seat and the flap respectively. Adjacent sets of flaps are connected by a flexible connector.

[0016] The beneficial effects of this invention are: By incorporating dustproof components, the hood can form a closed cavity in the profile processing area, spatially limiting the spread of debris and dust. Combined with the sealing components at both ends of the hood, dynamic sealing is achieved during the profile conveying process, preventing debris from escaping from both ends of the hood. At the same time, the two sets of elastic sealing covers symmetrically arranged in the top channel of the hood, together with multiple sets of telescopic components, can effectively seal the area covered by the guide kit as the guide kit moves with the laser cutting head, effectively preventing debris from the cutting area from drifting out from the gaps around the guide kit, reducing the probability of debris sticking to the cutting surface or scattering on the upper surface of the profile after large-scale splashing.

[0017] By setting up an adsorption component, when the laser cutting head moves to the corresponding processing area, the trigger plate on the guide kit cooperates with the inclined surface of the conical trigger block to drive the rack to move down and drive the cover plate to rotate and open through gear transmission. This allows the adsorption nozzle to accurately align with the area where the debris is generated for targeted adsorption. After the laser cutting head leaves, the cover plate can quickly reset and seal the adsorption nozzle port, avoiding the waste of negative pressure caused by the continuous opening of the adsorption nozzle in non-processing areas. The concentrated airflow improves the adsorption efficiency of the cutting area, ensuring that various debris such as high-temperature droplets and medium-temperature particles can be removed in a timely manner.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-2 The present invention provides a profile laser cutting machine for manufacturing metal casement window frames, including a base frame 1, a bracket 2 mounted on the base frame 1, a tooling fixture 3 mounted on the bracket 2 for clamping and conveying profiles, and a laser cutting device 4 mounted on the base frame 1. The laser cutting device 4 includes a frame 41, a laser cutting head 42, and an X-axis guide rail 43, a Y-axis guide rail 44, and a Z-axis guide rail 45 mounted on the frame 41 for driving the laser cutting head 42 to move.

[0022] Reference Figures 2-4 It also includes a dustproof component 5 and multiple adsorption components 6.

[0023] Specifically, the dustproof component 5 is mainly used to enclose the profile processing area to limit the spread of splashes and dust. The dustproof component 5 includes a cover 51 covering the profile processing area, side plates 52 symmetrically fixed on both sides of the cover 51, and a mounting bracket 53 connecting the side plates 52 and the bracket 2. The mounting bracket 53 allows the cover 51 to be stably installed above the bracket 2, forming a closed processing cavity. The top of the cover 51 has a channel 54 for the laser cutting head 42 to pass through. The laser cutting head 42 can move inside the cover 51 to cut the profile. Two sets of elastic sealing covers 55 are symmetrically arranged in the channel 54. A guide kit 56 is slidably connected between the two sets of elastic sealing covers 55. The laser cutting head 42 can move through the guide kit 56. When the laser cutting head 42 moves, the guide kit 56 will slide between the elastic sealing covers 55. The dustproof component 5 can form a relatively closed space in the cutting area.

[0024] Reference Figure 4 Multiple adsorption components 6 are equidistantly distributed along the length of the cover 51. Each adsorption component 6 includes an adsorption nozzle 61 fixed inside the cover 51 and an openable cover plate 62. The cover plate 62 is used to seal the port of the adsorption nozzle 61 in the non-processing area. The port of the adsorption nozzle 61 is located in the area near the top on both sides of the profile. When the laser cutting head 42 moves, it can drive the cover plate 62 of the corresponding processing area to open and close, so that the adsorption nozzle 61 can specifically adsorb the splashes and dust in the area. After the laser cutting head 42 leaves, the cover plate 62 can reset and seal. By setting the adsorption components 6 that open as needed, the adsorption airflow can be concentrated in the cutting area, improving the adsorption efficiency.

[0025] Reference Figure 1 , Figures 3-4 and Figure 12 It also includes a negative pressure tube assembly 7, a negative pressure device 9, and a controller 10. The ends of multiple suction nozzles 61 that are away from the cover plate 62 extend to the outside of the cover 51 and are connected to the negative pressure tube assembly 7. The negative pressure device 9 provides negative pressure suction power to the suction nozzles 61 through the negative pressure tube assembly 7, thereby generating negative pressure at the suction nozzles 61 to suck in metal splashes and dust. The negative pressure device 9 is electrically connected to the controller 10, and the start and stop of the negative pressure device 9 and the suction power can be controlled as needed.

[0026] Reference Figures 5-6A gap is provided between the two sets of elastic sealing covers 55 for the guide kit 56 to slide. Furthermore, each set of elastic sealing covers 55 includes a grooved section 551, a vertical section 552 symmetrically arranged on the grooved section 551, a corrugated section 553 connected to the vertical section 552, and a horizontal section 554 connected to the corrugated section 553. The horizontal section 554 is fixed to the inner wall of the channel 54. The grooved section 551 and the corrugated section 553 are preferably made of rubber material. Rubber material has excellent elasticity and durability, effectively resisting cutting spatter and localized high temperatures that may exist in the processing environment, while providing sufficient deformation capacity to accommodate the sliding of the guide kit 56. The 6 includes a hollow sleeve 561, a protrusion 562 fixed on the hollow sleeve 561, and a conical cover 563 fixed to the bottom of the hollow sleeve 561. The laser cutting head 42 passes through the hollow sleeve 561 and the conical cover 563. The hollow sleeve 561 slides in contact with the vertical section 552, and the protrusion 562 slides in contact with the groove section 551. The groove section 551 and the protrusion 562 cooperate to guide and support the device. At the same time, the elasticity of the groove section 551 and the corrugated section 553 provides a flexible seal when the guide kit 56 slides. The conical cover 563 helps to further limit the spatter below the cutting head within the adsorption range of the adsorption assembly 6.

[0027] To further enhance the stability of the guide assembly 56 during sliding, multiple sets of telescopic components 57 are equidistantly arranged along the length direction between the channel 54 and the vertical section 552. Each set of telescopic components 57 includes a sleeve 571 hinged to the side wall of the channel 54, a rod 572 movably inserted into the sleeve 571, and a first spring 573 disposed on the rod 572. The end of the rod 572 facing away from the sleeve 571 is hinged to the vertical section 552. When the guide assembly 56 slides, the telescopic component 57 provides elastic support and buffering through the first spring 573 inside, so that the vertical section 552 can maintain close contact with the hollow sleeve block 561 during sliding, further improving the sealing effect.

[0028] Reference Figures 7-11The adsorption assembly 6 also includes a shaft 63 fixed to the cover plate 62, a support 64 rotatably engaged with the shaft 63, a gear 65 fixed to the shaft 63, a rack 66 meshing with the gear 65, a conical trigger block 67 fixed to the top of the rack 66, and a trigger plate 69 fixed to the guide assembly 56. The trigger plate 69 and the conical trigger block 67 are both inclined surfaces. The rack 66 slides through the support 64, and the adsorption nozzle 61 has a hole for the rack 66 to move downward. When the laser cutting head 42 moves with the guide assembly 56, the trigger plate 69 slides with the guide assembly 56 and can sequentially abut against the conical trigger block 67. Since the trigger plate 69 and the conical trigger block 67 are inclined surfaces, the adsorption assembly 69 is suitable for the adsorption assembly 63. The contact of the trigger plate 69 drives the rack 66 to move downward. When the rack 66 moves downward, it can pass through the hole and, through its meshing with the gear 65, drive the shaft 63 to rotate, thereby causing the cover plate 62 fixed on the shaft 63 to rotate and open. When the laser cutting head 42 leaves the area of ​​the adsorption assembly 6, the trigger plate 69 disengages from the conical trigger block 67. It should be noted that the top of the conical trigger block 67 is movably provided with a ball bearing 671. The ball bearing 671 slides in contact with the bottom of the trigger plate 69. When the trigger plate 69 slides with the guide kit 56 and abuts against the conical trigger block 67 in sequence, the setting of the ball bearing 671 can effectively reduce the friction between the trigger plate 69 and the conical trigger block 67 during sliding.

[0029] To achieve automatic reset of the cover plate 62, a second spring 68 is provided on the rack 66. The two ends of the second spring 68 are fixed to the conical trigger block 67 and the support base 64, respectively. When the trigger plate 69 drives the rack 66 to move and open the cover plate 62, once the trigger plate 69 leaves the conical trigger block 67, the elastic force of the second spring 68 will reset the rack 66 to the initial position, thereby driving the cover plate 62 to close and seal the suction nozzle 61 port.

[0030] Furthermore, both ends of the shaft 63 are provided with a first torsion spring 631. The two ends of the first torsion spring 631 are fixed to the cover plate 62 and the support seat 64 respectively. When the cover plate 62 is opened, the first torsion spring 631 is twisted and stores energy. When the opening force is released, the elastic force of the first torsion spring 631 will quickly return the cover plate 62 to the closed position, further ensuring the sealing effect.

[0031] Reference Figure 13The two ends of the cover 51 are symmetrically provided with sealing components 8. Specifically, the sealing components 8 include four sets of mounting seats 81 distributed circumferentially along the edge of the port of the cover 51. Each set of mounting seats 81 is hinged with a flap 82 for fitting the surface of the profile through a rotating shaft. A second torsion spring 83 is provided on the rotating shaft. The two ends of the second torsion spring 83 are fixed to the mounting seat 81 and the flap 82 respectively, so that the flap 82 can fit tightly against the profile entering and exiting the cover 51 to form a dynamic seal. Adjacent sets of flaps 82 are connected by flexible connectors 84 to close the gap between adjacent flaps 82, further enhancing the sealing effect.

[0032] The working principle of a laser cutting machine for manufacturing metal casement window frames is as follows: First, a long strip of aluminum alloy or thermally broken aluminum profile is horizontally clamped onto the tooling fixture 3 of the bracket 2. The first section of the profile body is processed into the cover 51 of the dustproof component 5. Under the action of the second torsion spring 83, the flaps 82 of the sealing components 8 at both ends of the cover 51 are tightly attached to the surface of the profile. The flexible connectors 84 between adjacent flaps 82 seal the gaps, forming a closed initial processing environment. Subsequently, the controller 10 controls the negative pressure device 9 to start, and the negative pressure pipe assembly 7 provides suction to the suction nozzles 61 of each suction component 6. The negative pressure adsorption power is supplied, and the laser cutting equipment 4 is started. The laser cutting head 42 is driven by the X-axis guide rail 43, Y-axis guide rail 44, and Z-axis guide rail 45 to begin laser cutting the profile according to the preset processing path. The laser cutting head 42 is movably inserted into the guide kit 56, and drives the guide kit 56 to move along the channel 54 at the top of the cover 51. When the laser cutting head 42 moves above the first processing area, the guide kit 56 slides synchronously. The grooved section 551 and corrugated section 553 of the elastic sealing cover 55 undergo elastic deformation as the guide kit 56 moves. The telescopic component 57 passes through... An internal first spring 573 provides elastic support, ensuring the sealing continuity between the guide assembly 56 and the elastic sealing cover 55. During this process, the trigger plate 69 on the guide assembly 56 contacts the conical trigger block 67 of the corresponding area adsorption assembly 6. Due to the inclined surface engagement between the trigger plate 69 and the conical trigger block 67, a thrust is applied to move the conical trigger block 67 and the rack 66 connected to it downwards. The rack 66 drives the shaft 63 to rotate through meshing with the gear 65, thereby causing the cover plate 62 to rotate and open. The adsorption nozzle 61 then begins to adsorb the metal debris generated during the cutting process. After the laser cutting head 42 completes the feature processing of the area according to the preset drawing, the laser cutting head 42 drives the guide kit 56 to continue moving. The adsorption components 6 of the subsequent area are opened in sequence under the action of the trigger plate 69. The adsorption components 6 of the unprocessed area are kept in a sealed state by the second spring 68 and the first torsion spring 631. The debris generated by cutting is extracted by the negative pressure device 9 through the adsorption nozzle 61 and the negative pressure tube assembly 7 until the cutting of the entire profile is completed. Finally, the controller 10 controls each component to stop in sequence, the tooling fixture 3 releases the profile, and the single processing cycle is completed.
