Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, and more specifically to a laser cutting device for metal door and window processing. Background Technology

[0002] In the mass production of metal doors and windows, square and rectangular tubes, as a basic profile, often need to be processed into tubes of specific lengths using laser cutting equipment. In order to meet the requirements of subsequent welding processes, it is often necessary to cut a straight end at one end and a bevel at a certain angle at the other end.

[0003] Currently, such laser cutting equipment can efficiently complete the aforementioned cutting tasks. However, existing technologies generally suffer from a significant drawback: the cut surface after laser cutting often retains slag, oxide layers, or microscopic unevenness, directly affecting the accuracy and strength of subsequent welding or assembly. To address this issue, current production lines typically require transferring the fittings to a separate grinding station after the cutting process, where they undergo secondary processing manually or with specialized equipment. This separate processing mode not only increases equipment investment, floor space, and workpiece turnaround time, reducing overall production efficiency, but more importantly, it requires operators to frequently change grinding tools or manually adjust the grinding angle when faced with two drastically different cut shapes—straight and beveled. This process is cumbersome and makes it difficult to ensure consistency in grinding angles across batches of products. Even with semi-automated equipment, complex sensing and control systems are often required to identify and switch grinding modes, increasing equipment costs and maintenance complexity. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a laser cutting device for metal door and window processing to solve the problems existing in the background art.

[0009] Preferably, the two grinding plates are hinged together by connecting rods, and two connecting rods are symmetrically arranged. A power transmission component is provided between the two rotating rods.

[0010] Preferably, the traction mechanism includes a mounting housing and a rack. The mounting housing is fixedly mounted on the receiving frame. A mounting shaft is rotatably mounted inside the mounting housing. One end of the mounting shaft is fixedly connected to a rotating disk, and the other end of the mounting shaft passes through the inner wall of the mounting housing and extends outward. A hollow disk is fixedly connected to the other end of the mounting shaft.

[0011] Preferably, a traction wheel is coaxially rotatably mounted inside the hollow disc, and a gear is coaxially fixedly connected to the traction wheel.

[0015] The beneficial effects of this invention are: In this invention, a grinding mechanism with self-switching state function is integrated next to the laser cutting machine.

In addition, this design effectively solves the problem of poor consistency caused by manual adjustment of grinding angle in traditional methods. Through mechanical linkage, it ensures that each state switch is accurate and reliable, guaranteeing a high degree of uniformity in the grinding quality of all pipe fittings in mass production. This provides a high-quality interface foundation for subsequent welding processes, improving the structural strength and aesthetics of door and window products. Furthermore, the integrated design eliminates the need for a separate grinding station and intermediate handling links, saving equipment costs and factory space, reducing the labor intensity of workers, and achieving efficient, intelligent, and low-cost automated production.

[0026] 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.

[0027] Reference Figures 1 to 4 This invention provides a laser cutting equipment for metal door and window processing, including a base 1. The top of the base 1 is provided with a conveying mechanism 2, an electric slide rail 3, a laser cutter 4, and a receiving frame 5. The receiving frame 5 is equipped with a grinding mechanism 6 and a traction mechanism 7. The conveying mechanism 2 is used to drive a rectangular tube through the bottom of the laser cutter 4. The laser cutter 4 is used to cut the rectangular tube into multiple tubes with one end straight and the other end beveled. The grinding mechanism 6 is provided with a beveled grinding state and a straight grinding state. The beveled grinding state of the grinding mechanism 6 is used to grind the tubes after the laser cutter 4 has completed the bevel cutting. The straight grinding state of the grinding mechanism 6 is used to grind the tubes after the laser cutter 4 has completed the straight cutting. The traction mechanism 7 is used to control the grinding mechanism 6 to switch between the beveled grinding state and the straight grinding state.

[0028] Reference Figures 1 to 5 A first chuck 21 is fixedly installed at the output end of the conveying mechanism 2, and a movable frame 31 is slidably installed on the electric slide rail 3. A second chuck 32 is fixedly installed on the top of the movable frame 31. By setting the fixed first chuck 21 and the movable second chuck 32 that can move along the electric slide rail 3, precise positioning and coordinated clamping of the rectangular tube raw material and the cut tube fittings are achieved, ensuring the stability of the workpieces during cutting and grinding. At the same time, the moving function of the second chuck 32 provides action execution guarantee for separating the tube fittings after cutting and forming the gap required for grinding operations.

[0029] A connector 51 is fixedly installed on the receiving frame 5. The connector 51 is used to fix the connection to the linear motion module. The design of the connector 51 provides a standardized and modular interface, which enables the entire grinding mechanism 6 and traction mechanism 7 to be connected to an external linear drive source, enhances the flexibility of equipment layout, facilitates integration into different automated production lines, and ensures the accurate transmission of drive actions.

[0030] The grinding mechanism 6 includes two grinding plates 61 and two rotating rods 62. The rotating rods 62 are rotatably mounted on the top of the support frame 5, with two corresponding grinding plates 61. The grinding plates 61 are fixedly mounted on the surface of the rotating rods 62. The two grinding plates 61 are hinged together by two connecting rods 63. A power transmission component 64 is provided between the two rotating rods 62. Preferably, the power transmission component 64 is a chain drive structure. This dual-grinding-plate 61 linkage structure ensures absolute synchronization of the two grinding surfaces during angle changes through the hinged connecting rods 63. The power transmission component 64 effectively distributes the driving force and improves stability, making the two grinding plates 61 move as a single unit. Its compact structure and high power transmission efficiency are the foundation for achieving stable and uniform grinding operations.

[0031] In summary, by setting up a grinding mechanism 6 consisting of a grinding plate 61, a rotating rod 62, a connecting rod 63, and a power transmission component 64, instantaneous and adaptable grinding of the cut edges of laser-cut pipe fittings is achieved. The two grinding plates 61 are linked by symmetrically hinged connecting rods 63, ensuring the synchronization, angle consistency, and stability of the two grinding surfaces during state switching. This allows for precise matching of straight or beveled edges, enabling uniform and comprehensive grinding of the cut edges. This structure transforms complex angle adjustments into rotational motion around a fixed axis, resulting in rapid response, reliable operation, and avoiding structural redundancy and increased costs associated with using multiple independent grinding units. The power transmission component 64 further simplifies the drive logic; only one power input is needed to control the coordinated operation of the two grinding plates 61, improving the rigidity and motion accuracy of the mechanism. This provides a mechanical basis for obtaining high-quality, burr-free cut surfaces and solves the technical bottlenecks of cumbersome tool replacement and difficulty in achieving uniform angles in traditional methods.

[0032] Reference Figures 1 to 8The traction mechanism 7 includes a mounting housing 71 and a rack 76. The mounting housing 71 is fixedly mounted on the receiving frame 5. A mounting shaft 72 is rotatably mounted inside the mounting housing 71. One end of the mounting shaft 72 is fixedly connected to a rotating disk 73. The other end of the mounting shaft 72 passes through the inner wall of the mounting housing 71 and extends outward. A hollow disk 77 is fixedly connected to the other end of the mounting shaft 72. A traction wheel 78 is coaxially rotatably mounted inside the hollow disk 77. A gear 79 is coaxially fixedly connected to the traction wheel 78. The rack 76 is fixedly mounted on the base 1. The gear 79 matches the rack 76. A ratchet 771 is provided on the inner wall of the hollow disk 77. A trigger assembly is provided on the outer surface of the traction wheel 78. Multiple trigger assemblies are provided. The meshing of gear 79 and fixed rack 76 cleverly transforms the overall linear movement into the rotational motion of traction wheel 78. The ratchet 771 set in the hollow disc 77 and the multiple trigger components on the traction wheel 78 together form a unidirectional transmission structure. Its core function is to determine whether to output torque according to the direction of movement, thereby realizing the control logic of triggering action when moving forward and idling over when returning.

[0033] The triggering assembly includes a connecting shaft 781, a stabilizing block 782, and a compression spring 783. The connecting shaft 781 is rotatably mounted on the traction wheel 78, and the stabilizing block 782 is fixedly mounted on the surface of the connecting shaft 781. One end of the compression spring 783 is fixedly connected to the stabilizing block 782, and the other end is fixedly connected to the outer surface of the traction wheel 78. A triggering surface 7821 is provided on the stabilizing block 782. The connecting shaft 781 provides the pivot point for the stabilizing block 782, and the compression spring 783 gives it elastic restoring capability. The triggering surface 7821 ensures effective thrust transmission when in contact with the ratchet 771. In the reverse direction, the stabilizing block 782 can squeeze the compression spring 783 and swing around the connecting shaft 781 to slide past the ratchet 771. This design mechanically achieves directional selectivity of action.

[0034] A transmission shaft 74 and a rotating shaft 75 are rotatably mounted inside the mounting housing 71. A moving rod 742 is fixedly connected to one end of the transmission shaft 74. A guide hole 7421 is provided on the moving rod 742. A guide post 731 is eccentrically provided on the rotating disk 73. The guide post 731 is located inside the guide hole 7421. A gear 2 741 is fixedly connected to the surface of the transmission shaft 74. A worm gear 751 and a gear 3 752 are fixedly connected to the surface of the rotating shaft 75. Gear 2 741 and gear 3 752 are meshed together. One end of a rotating rod 62 extends into the mounting housing 71, and a worm wheel 753 is fixedly connected to one end of the rotating rod 62. The worm wheel 753 is meshed with the worm gear 751. The eccentrically positioned guide post 731 and the motion rod 742 with the guide hole 7421 constitute a variant of the crank-slider structure, which transforms the continuous rotational motion of the mounting shaft 72 into the reciprocating oscillation of the transmission shaft 74. This is the key link in realizing the transformation of motion form. The meshing of gear two 741 and gear three 752 realizes the transmission and acceleration of motion. The cooperation between the worm gear 751 and the worm wheel 753 has a self-locking characteristic, which can ensure that the grinding plate 61 is locked at the required angle in the non-drive state and maintain the stability of the working posture.

[0035] In summary, by setting up a traction mechanism 7 consisting of a mounting housing 71, a rack 76, a hollow disc 77, a ratchet 771, and a trigger assembly, the automatic identification and switching of the working state of the grinding mechanism 6 is achieved. The core advantage of this mechanism lies in its mechanical triggering and control logic. When the equipment moves and the gear meshes with the fixed rack, the rotation direction of the traction wheel 78, in conjunction with the ratchet 771, converts the linear motion into a unidirectional intermittent rotation of the mounting shaft 72, thereby driving the grinding mechanism 6 to complete the state switching. The setting of the compression spring 783 and the stabilizing block 782 in the trigger assembly allows the traction wheel 78 to smoothly slide past the ratchet 771 without driving the mounting shaft 72 when rotating in the opposite direction, thus ensuring the uniqueness and accuracy of the state switching action. That is, the switching only occurs when the grinding mechanism 6 moves forward and approaches the workpiece, and the state remains unchanged when returning. This design requires no additional sensors, controllers, or electric actuators, utilizing only the reciprocating motion of the equipment itself as the power source and control signal. This simplifies the system configuration and improves the reliability, durability, and cost-effectiveness of the equipment, making it a key control element for achieving automated production line operations of "one piece, one grinder".

[0036] The working principle of this invention is as follows: The conveying mechanism 2 conveys the rectangular tube, allowing it to pass through the first chuck 21 and the second chuck 32 in sequence. Then, the first chuck 21 and the second chuck 32 clamp and fix the rectangular tube. The laser cutting machine 4 performs laser cutting on the rectangular tube. Under the action of the laser cutting machine 4, a bevel is formed at the cut. The electric slide rail 3 then pulls the movable frame 31 and the second chuck 32 to move in the same direction away from the first chuck 21. The movement of the second chuck 32 drives the cut tube to move synchronously, forming a gap between the tube and the rectangular tube.

[0037] Subsequently, the linear motion module drives the receiving frame 5 to move horizontally in a linear motion via the connector 51. The grinding mechanism 6 and the traction mechanism 7 move synchronously with the receiving frame 5 towards the gap. During this process, gear 79 first contacts and meshes with the rack 76. As gear 79 moves along the rack 76, the traction wheel 78 rotates counterclockwise around its own axis, and the stabilizing block 782 rotates synchronously counterclockwise with the traction wheel 78. During this process, the trigger plane 7821 on the stabilizing block 782 abuts against the ratchet 771, causing the hollow disk 77 and the mounting shaft 72 to rotate synchronously around the axis of the mounting shaft 72. The rotation of the mounting shaft 72 drives the rotating disk 73 to rotate synchronously around the axis of the mounting shaft 72. During the first half of one revolution of the rotating disk 73, the guide post 731 on the rotating disk 73 moves along the guide hole 7421 on the moving rod 742, causing the moving rod 742 and the transmission shaft 74 to rotate as a whole around the axis of the transmission shaft 74. The rotation of the transmission shaft 74 drives the rotating shaft 75 to rotate synchronously around its own axis through the gear two 741 and the gear three 752. The rotation of the rotating shaft 75 drives a rotating rod 62 to rotate synchronously around its own axis through the worm gear 751 and the worm wheel 753. The rotation of the rotating rod 62 drives another rotating rod 62 to rotate synchronously around its own axis through the power transmission component 64. The rotation of the rotating rod 62 drives the grinding plate 61 to rotate synchronously around the axis of the rotating rod 62.

[0038] After gear 79 separates from rack 76, the rotating disk 73 completes the first half of one revolution. At this time, the grinding mechanism 6 switches from straight grinding to oblique grinding, and the grinding plate 61 is arranged at an angle. Then, the linear motion module continues to drive the grinding mechanism 6 and the traction mechanism 7 to move towards the gap. During this process, since gear 79 and rack 76 do not have any contact, the grinding mechanism 6 maintains the oblique grinding state. The grinding plate 61 passes through the gap and contacts the two bevel end faces of the laser cutting. As the grinding plate 61 moves along the bevel end faces, the bevel end faces are ground.

[0039] Subsequently, the linear motion module drives the grinding mechanism 6 and the traction mechanism 7 to move in opposite directions. During this process, gear 79 contacts and meshes with rack 76 again. As gear 79 moves along rack 76, traction wheel 78 rotates clockwise around its own axis, and stabilizing block 782 rotates clockwise synchronously with traction wheel 78. During this process, the trigger plane 7821 on stabilizing block 782 does not come into contact with ratchet 771, and compression spring 783 switches back and forth between compression and tension. Stabilizing block 782 gradually passes over each ratchet 771. Mounting shaft 72 and hollow disk 77 remain stationary, and grinding mechanism 6 remains in oblique grinding state. After gear 79 separates from rack 76, the linear motion module continues to drive grinding mechanism 6 and traction mechanism 7 back to their initial positions.

[0040] Afterwards, chuck 21 and chuck 32 release their clamps, and the laser-cut tube is transferred by the staff to the subsequent production and processing equipment. The electric slide rail 3 controls chuck 32 to move towards chuck 21 and back to its initial position. The conveying mechanism 2 conveys the rectangular tube through chuck 21 and chuck 32 in sequence. Chuck 21 and chuck 32 then clamp and fix the rectangular tube. The laser cutting machine 4 performs laser cutting on the rectangular tube. Under the action of the laser cutting machine 4, a straight edge is formed at the cut. The electric slide rail 3 then pulls chuck 32 to move away from chuck 21. The movement of chuck 32 drives the cut tube to move synchronously, and a gap is formed between the tube and the rectangular tube again.

[0041] Subsequently, the linear motion module drives the receiving frame 5 to move horizontally in a linear motion via the connector 51. The grinding mechanism 6 and the traction mechanism 7 move synchronously with the receiving frame 5 towards the gap. During this process, gear 79 first contacts and meshes with the rack 76. As gear 79 moves along the rack 76, the traction wheel 78 rotates counterclockwise around its own axis, and the stabilizing block 782 rotates synchronously counterclockwise with the traction wheel 78. During this process, the trigger plane 7821 on the stabilizing block 782 abuts against the ratchet 771, causing the hollow disk 77 and the mounting shaft 72 to rotate synchronously around the axis of the mounting shaft 72. The rotation of the mounting shaft 72 drives the rotating disk 73 to rotate synchronously around the axis of the mounting shaft 72. As the rotating disk 73 completes the second half of one rotation cycle, the guide post 731 on the rotating disk 73 moves along the guide hole 7421 on the moving rod 742, causing the moving rod 742 and the transmission shaft 74 to rotate as a whole around the axis of the transmission shaft 74. The rotation of the transmission shaft 74 drives the rotating shaft 75 to rotate synchronously around its own axis through the gear two 741 and the gear three 752. The rotation of the rotating shaft 75 drives a rotating rod 62 to rotate synchronously around its own axis through the worm gear 751 and the worm wheel 753. The rotation of one rotating rod 62 drives another rotating rod 62 to rotate synchronously around its own axis through the power transmission component 64. The rotation of the rotating rod 62 drives the grinding plate 61 to rotate synchronously around the axis of the rotating rod 62.

[0042] After gear 79 separates from rack 76, the rotating disk 73 completes the second half of its rotation. At this time, the grinding mechanism 6 switches from oblique grinding to straight grinding, and the grinding plate 61 is arranged vertically. Then, the linear motion module continues to drive the grinding mechanism 6 and the traction mechanism 7 to move towards the gap. During this process, since gear 79 and rack 76 do not have any contact, the grinding mechanism 6 maintains the straight grinding state. The grinding plate 61 passes through the gap and contacts the two straight end faces of the laser cutting. As the grinding plate 61 moves along the straight end faces, the straight end faces are ground.

[0043] Subsequently, the linear motion module drives the grinding mechanism 6 and the traction mechanism 7 to move in opposite directions. During this process, gear 79 contacts and meshes with rack 76 again. As gear 79 moves along rack 76, traction wheel 78 rotates clockwise around its own axis, and stabilizing block 782 rotates clockwise synchronously with traction wheel 78. During this process, the trigger plane 7821 on stabilizing block 782 does not come into contact with ratchet 771, and compression spring 783 switches back and forth between compression and tension. Stabilizing block 782 gradually passes over each ratchet 771. Mounting shaft 72 and hollow disk 77 remain stationary, and grinding mechanism 6 maintains a straight grinding state. After gear 79 separates from rack 76, the linear motion module continues to drive grinding mechanism 6 and traction mechanism 7 back to their initial positions.

[0044] Afterwards, chuck 21 and chuck 32 release their clamps, and the laser-cut tubes are transferred by the workers to the subsequent production and processing equipment. The electric slide rail 3 controls chuck 32 to return to its initial position, and the conveying mechanism 2 conveys the rectangular tubes through chuck 21 and chuck 32 in sequence. Chuck 21 and chuck 32 then clamp and fix the rectangular tubes, and the above steps are repeated in a continuous cycle.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
