Description

Technical Field

[0001] This utility model relates to the technical field of metal pipe processing equipment, and in particular to a heavy-duty laser pipe cutting machine. Background Technology

[0002] Laser tube cutting machines, as key equipment in tube processing, are widely used in the processing of heavy-duty tubes (such as large-diameter, long steel pipes). Traditional heavy-duty laser tube cutting machines typically consist of a frame, a fixed laser cutting head, multiple chucks, and a loading rack. Specifically, the solution described in Chinese utility model patent CN220993145U has the following problems:

[0003] 1. Multiple sets of chucks need to be installed on both the front and rear sides of the fixed laser cutting head to achieve clamping and transportation on the loading and unloading sides, resulting in a large and complex equipment with high cost.

[0004] 2. A feeding mechanism needs to be installed next to each storage conveyor belt to feed raw material pipes into the frame. The pipes are then clamped by a chuck assembly, and multiple feeding mechanisms are used to feed pipes of different lengths. Simultaneously, a feeding device is also needed on the unloading side. This device includes a storage rack and a feeding plate. The feeding plate is rotatably mounted on the frame to receive cut pipes and flip them into the storage rack. This solution is complex, costly, and has poor compatibility with raw material pipes.

[0005] 3. The laser cutting head is fixed, and the waste material obtained from laser cutting is discharged from the through hole inside the frame, which makes cleaning and removal more troublesome.

[0006] These problems severely restrict the processing accuracy and automation level of heavy-duty laser tube cutting machines. Existing technologies urgently need improvement to address these issues. Summary of the Invention

[0007] To address the aforementioned problems, the purpose of this invention is to provide a heavy-duty laser tube cutting machine that offers advantages such as improved equipment integration, enhanced loading and unloading efficiency, and optimized waste disposal capabilities.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] This application provides a heavy-duty laser tube cutting machine, the technical solution of which is as follows: A heavy-duty laser tube cutting machine includes a frame, a laser tube cutting assembly and multiple chucks mounted on the frame and movable along the length of the frame, and a loading rack mounted next to the frame; two sets of tube handling devices are mounted between the loading rack and the frame and movable along the length of the frame; the two sets of tube handling devices can be relatively close or far apart to accommodate tubes of different lengths; the two sets of tube handling devices are respectively used to support or clamp the two ends of the raw material tube or the two ends of the cut tube unit to perform loading or unloading operations.

[0010] This technical solution automates the handling of raw pipe fittings and cut pipe fitting units by setting up two sets of pipe handling devices that can move along the length of the frame and have adjustable spacing. The two sets of pipe handling devices move parallel to the length of the frame, covering the working area between the loading rack and the frame, avoiding the cumbersome equipment caused by relying on chuck movement or adding multiple independent handling units in traditional solutions. The relative approaching or moving away of the two sets of handling devices directly adapts to the clamping requirements of pipe fittings of different lengths, eliminating the need for independent handling mechanisms for different specifications of pipes, thus simplifying the equipment structure. Furthermore, using two sets of pipe handling devices enables loading and unloading without the need for a chuck and unloading structure downstream of the laser cutting assembly, further simplifying the structure and reducing costs. Finally, the simultaneous support or clamping at both ends ensures the stability of long pipes during loading and unloading, while allowing the chuck to focus on fixing the pipe for cutting operations, avoiding process interruptions caused by the chuck needing to perform both clamping and conveying functions in traditional solutions.

[0011] Furthermore, this application proposes that multiple chucks be movable and arranged on the side of the frame; when two sets of pipe handling devices support or clamp the raw pipe fittings on the loading rack to the central axis of the chuck, the chuck moves to engage and clamp the raw pipe fittings. This technical solution breaks through the limitations of traditional fixed chuck layouts by setting the chucks as a modular structure that can move along the side of the frame. After the pipe handling device accurately positions both ends of the raw pipe fittings to the central axis of the chuck, the chuck actively moves to engage the fittings, instead of needing to push them axially to the center of the chuck for engagement as in traditional technology. This design allows the chuck spacing to be dynamically adjusted according to the actual pipe length, avoiding the problem of excessive equipment length caused by too many chucks, and achieving automatic centering and clamping of the pipes through the coordinated action of the chucks and handling devices. The feature of "the chucks being movable and arranged on the side of the frame" gives the chucks spatial freedom, providing the pipe handling device with more operating space during loading and unloading, making it less susceptible to interference from the chucks and frame; and providing a spatial basis for receiving and removing cutting waste later.

[0012] Furthermore, this application proposes that two sets of pipe handling devices are movably mounted on slide rails; the slide rails extend at least beyond the end of the frame, and a material unloading area is provided next to the portion of the slide rails extending beyond the end of the frame. This technical solution expands the working range of the pipe handling devices by setting up a movable material-supporting slide rail system. First, by installing two sets of pipe handling devices on the material-supporting slide rails, the handling devices can move a wide range along the slide rails, not only breaking through the length limitations of traditional fixed handling devices, but also being able to receive cut pipe fitting units for relocation and unloading. Specifically, the material-supporting slide rails extend beyond the end of the frame, and an independent unloading area is set next to this extension, forming a material unloading space physically separated from the processing area. This layout design allows cut pipe fitting units to be directly transported via the slide rails to a dedicated unloading area outside the frame, avoiding accumulation near the frame and interference with equipment operation. At the same time, the adjustable length of the slide rail extension allows for flexible adjustment of the capacity and position of the unloading area according to actual production needs, improving the system's adaptability to different specifications of pipes.

[0013] Furthermore, this application also proposes that the pipe handling device be a clamping robot.

[0014] Furthermore, this application proposes a waste conveying track located below the multiple chuck movement paths to collect and remove waste generated during laser cutting. This technical solution utilizes the waste conveying track to collect waste from the concentrated area below the chuck movement paths. Located directly below the chuck movement paths, the waste conveying track catches the waste falling during cutting, preventing it from scattering and accumulating in other areas of the machine frame. Continuous removal of waste via the conveying track solves the downtime and maintenance problems caused by traditional equipment relying on manual cleaning or independent collection systems, making it particularly suitable for handling large volumes of waste generated from heavy pipe cutting. The spatial relationship between the waste conveying track and the chuck movement paths ensures timely and automated waste collection, thereby improving the continuous operating efficiency of the equipment. In addition, the convenient placement of the waste conveying track relies on the multiple chucks being positioned on the side of the machine frame, allowing waste to fall directly into the track.

[0015] Furthermore, this application proposes that the waste conveying track includes a receiving track, a conveyor belt circulated within the receiving track, and a drive motor for driving the conveyor belt; an elevated section is provided at the end of the receiving track, and a waste outlet is provided within the elevated section. This technical solution achieves automated collection and efficient discharge of waste by optimizing the structural design of the waste conveying track. The receiving track, as the basic structure for waste collection, works in conjunction with the conveyor belt to form a continuous transport channel. The drive motor drives the conveyor belt to circulate, continuously transporting the waste generated from cutting to a designated area, preventing waste from accumulating under the frame. The elevated section creates an inclined slope at the end of the conveying track, using gravity to assist the waste in sliding towards the waste outlet, ensuring that the waste smoothly detaches from the equipment during transport. The waste outlet, as the centralized discharge point for waste, further reduces the need for manual intervention. The synergistic effect of these technical features improves waste processing efficiency, making it particularly suitable for scenarios involving large-volume waste generated from heavy pipe cutting.

[0016] Furthermore, this application proposes a pipe handling device comprising a movable base, a rotating arm mounted on the movable base, a lifting frame rotatably mounted on the rotating arm, and a support platform mounted on the lifting frame. The support platforms on the two sets of pipe handling devices cooperate to support raw material pipe fittings or pipe fitting units for loading and unloading. The rotating arm and lifting frame adapt to the orientation of loading and unloading through rotational movement. The lifting frame is used for lifting and lowering to adapt to the height of loading and unloading. This technical solution achieves flexibility and precise adaptation in pipe handling through a modular structural design. The movable base, as the overall moving carrier, allows the handling device to adjust the spacing along the length of the frame to adapt to the support requirements at both ends of pipe fittings of different lengths. The rotating arm changes the horizontal orientation of the support platform by rotating around its axis, enabling the handling device to adjust the inlet and outlet direction of the pipes according to the positional relationship between the loading rack and the frame, avoiding interference problems caused by mismatched orientations in traditional fixed robotic arms. The lifting frame adjusts the height of the support platform through vertical movement, ensuring precise alignment of the pipes with the chuck axis or the loading rack storage position during loading and unloading, eliminating the risk of pipe slippage due to height deviation. Two sets of support platforms work together to provide synchronous support to both ends of the pipe, maintaining the pipe's stability during handling, making it particularly suitable for the smooth transfer of heavy pipes. The combined motion mechanism of the rotating arm and the lifting frame allows a single handling device to cover loading and unloading scenarios at multiple angles and heights, significantly improving the equipment's adaptability to different working conditions.

[0017] Furthermore, this application also proposes that auxiliary baffles are provided on both sides of the support platform; the auxiliary baffles are hinged to the sides of the support platform and connected to the piston rod of the opening and closing cylinder.

[0018] Furthermore, this application proposes that a roller is also installed next to the support platform; the rolling direction of the roller is consistent with the length direction of the raw material pipe or pipe unit; the upper end face of the roller is slightly higher than the top surface of the support platform. This technical solution optimizes the pipe handling process by adding a specific structure. The rolling direction of the roller is consistent with the axial direction of the pipe, allowing the pipe to roll freely along its own length during handling, reducing frictional resistance and avoiding jamming caused by direct contact between the pipe and the support platform. The design of the upper end face of the roller being slightly higher than the top surface of the support platform creates a height difference, ensuring that the main body of the pipe is supported by the rolling of the roller for smooth movement, while the support platform provides auxiliary limiting to prevent the pipe from deviating during rolling. The synergistic effect of both significantly improves the load-bearing capacity of the handling device for heavy pipes, and at the same time, the physical structure adapts to the conveying needs of pipes of different lengths, achieving stable loading and unloading operations without additional adjustments.

[0019] Furthermore, this application proposes a pipe handling device including a clamping device disposed within a baffle plate. The clamping device comprises two sets of interconnected movable seats that can move closer or further apart, a lifting cylinder mounted on the movable seats, and a clamping plate mounted on the output end of the lifting cylinder. The lifting cylinder drives the clamping plate to extend out of or retract into the baffle plate. This technical solution, through the structural design of the clamping device, achieves flexible clamping and handling of pipes of different lengths. Specifically, the two sets of interconnected movable seats adjust the clamping distance by moving closer or further apart, thereby adapting to changes in pipe length. The lifting cylinder on the movable seats drives the clamping plate to adjust its vertical position, ensuring the clamping height is aligned with the pipe axis and preventing pipe misalignment. The clamping plate, as the actuator directly contacting the end of the pipe, is raised or lowered by the thrust of the lifting cylinder, thereby controlling the height of the clamping plate. The linkage design of the moving seat allows the two sets of clamping plates to move synchronously when adjusting the spacing, which simplifies the control logic and improves the coordination of clamping actions, thereby achieving efficient and precise pipe handling in a limited space.

[0020] Furthermore, a receiving box for receiving tail waste is provided on one end of the frame away from the unloading area, and a guide ramp for guiding tail waste into the receiving box.

[0021] As can be seen from the above, the heavy-duty laser tube cutting machine and its tube handling device and waste disposal system provided in this application realize the automatic loading and unloading of tubes of various specifications through two sets of adjustable spacing tube handling devices. Combined with a moving chuck and an integrated waste disposal system, it effectively solves the technical problems of large footprint, low loading and unloading efficiency and waste accumulation of traditional equipment. It has the advantages of improving equipment integration, enhancing loading and unloading efficiency and optimizing waste disposal capabilities. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0034] In existing technologies, laser tube cutting machines commonly suffer from complex structures and low loading / unloading efficiency in the heavy-duty tube processing field. Traditional solutions increase the number of chucks 3 to suppress the swinging of long tubes, resulting in an increased frame length 1 and greater difficulty in coordinated control. The loading / unloading process relies on the movement of the chucks 3 themselves or an independent robotic arm, leading to process interruptions and poor compatibility. Cutting waste falls directly and requires manual cleaning, affecting equipment operating efficiency.

[0035] To address the aforementioned issues, researchers discovered that existing equipment suffers from redundant handling mechanisms, resulting in an excessively long structure and an inability to accommodate various pipe specifications. Analysis revealed that simultaneous clamping at both ends of the pipe improves handling stability, but the traditional solution lacks an adjustable-spacing handling device 5. Further consideration was given to arranging the handling device 5 parallel to the frame 1, covering the loading rack 4 and the processing area, while adapting to pipes of different lengths through relative displacement. This resulted in a solution employing two sets of movable handling devices 5 operating simultaneously, simplifying the structure and preventing interruptions in the cutting process.

[0036] like Figures 1-7As shown, this embodiment relates to a heavy-duty laser tube cutting machine, which includes a frame 1, a laser tube cutting assembly 2, a chuck 3, and a loading rack 4. Two sets of tube handling devices 5, movable in a parallel direction, are arranged between the loading rack 4 and the frame 1. The two sets of devices can move relatively close or far apart to accommodate tubes of different lengths, respectively supporting or clamping the ends of raw material tubes 6 or the ends of cut tube units 7 to perform loading and unloading operations. The tube handling device 5 refers to a material transfer mechanism that can move along the length of the frame 1. Specifically, it can be implemented using a combination of a slide rail 8 and a drive motor, and its movement range covers the working area from the loading rack 4 to the frame 1. "Relatively close or far apart" means that the distance between the two sets of devices is adjusted through an independent drive system, for example, using a servo motor in conjunction with a screw drive mechanism to match the distance between the handling devices 5 to the length of the tube. "Supporting or clamping" refers to the method of fixing the ends of the tubes, specifically using mechanical grippers or bracket structures to ensure the stability of the tubes during handling.

[0037] Specifically, two sets of conveying devices 5 are arranged parallel to the frame 1 and move synchronously to the loading rack 4 during loading and unloading. The spacing between the two sets of devices 5 is adjusted so that their clamping points correspond to the actual length of the pipe to be conveyed. During conveying, the devices 5 simultaneously support or clamp both ends of the pipe to prevent bending deformation caused by single-point force. After clamping, the conveying device 5 moves along the slide rail 8 to the central axis of the chuck 3, at which point the chuck 3 moves to fix the pipe. After cutting, the conveying device 5 clamps both ends of the pipe unit 7 again and transfers it to the unloading area 9.

[0038] Compared to existing technologies, traditional solutions rely on the movement of the chuck 3 to transport pipes, leading to interruptions in the cutting process and increased equipment length. This solution utilizes an independent handling device 5 for material transfer, allowing the chuck 3 to focus on fixing the pipe for cutting. Existing technologies with multiple independent loading units are simplified into two adjustable-spacing devices 5, reducing mechanical complexity and improving compatibility with pipes of different lengths. Through this technical solution, this application achieves automated connection of the loading and unloading processes, eliminating processing interruptions caused by the movement of the chuck 3 in traditional solutions. The adjustable-spacing handling device 5 reduces the equipment footprint and avoids the need for separate mechanisms for different pipe specifications. Synchronous clamping at both ends ensures the stability of long pipe handling and reduces positioning errors caused by vibration. The integrated handling system simplifies the equipment structure, reducing manufacturing costs and maintenance difficulty.

[0039] Specifically, multiple chucks 3 are movable and mounted on the side of the frame 1. When the two sets of pipe handling devices 5 support or clamp the raw material pipe fittings 6 on the loading rack 4 to the central axis of the chucks 3, the chucks 3 move to engage and clamp the raw material pipe fittings 6. The multiple chucks 3 being movable and mounted on the side of the frame 1 means that the chucks 3 are installed on the side of the frame 1 via slide rails or linear modules. Specifically, a servo motor can drive a ball screw to move the chucks 3 along the length of the frame 1. This feature allows the chucks 3 to dynamically adjust their spacing according to the pipe length and the length of the cutting unit, avoiding excessive equipment length due to fixed chuck spacing. The movement of the chucks 3 to engage and clamp the raw material pipe fittings 6 means that after the handling device 5 completes the pipe positioning, the chucks 3 actively move towards the central axis of the pipe. Specifically, a hydraulic cylinder or electric push rod can drive the chuck 3 jaws to close, achieving engagement. This feature, through the coordinated action of the chucks 3 and the handling device 5, ensures automatic centering during pipe clamping, eliminating manual adjustment errors.

[0040] Specifically, during the feeding process, the chuck 3 is first moved so that the distance between the two chucks 3 is greater than the length of the raw material pipe fitting 6. When the pipe handling device 5 lifts both ends of the raw material pipe fitting 6 to the height of the central axis of the chuck 3, the chuck 3 moves along the side slide rail of the frame 1 to a position aligned with the pipe axis, and then the clamps close to complete the fitting. The movement path of the chuck 3 covers the entire length of the side of the frame 1, and the clamping position can be freely adjusted according to the pipe length, eliminating the need for a fixed chuck assembly. The handling device 5 only needs to initially position the pipe in the axial direction, and the chuck 3 achieves precise clamping through active movement. The cooperation of the two reduces the complex transmission mechanism required for axial pushing of the pipe in traditional technologies. Through the above technical solution, this application solves the problems of difficult pipe positioning and redundant equipment caused by the fixed chuck 3 layout, and realizes the cooperative clamping of the chuck 3 and the handling device 5. The active movement of the chuck 3 to attach the pipe improves clamping accuracy and avoids manual intervention; the function of dynamically adjusting the spacing of the chuck 3 simplifies the equipment structure and reduces the floor space; at the same time, the design of the chuck 3 moving along the side of the frame 1 frees up space for the movement of the pipe handling device 5 and the setting of the waste conveying track 10, avoiding interference.

[0041] In a further embodiment, two sets of pipe handling devices 5 are movably mounted on slide rails 8, which extend at least beyond the end of the frame 1. A discharge area 9 is located adjacent to the portion of the slide rails 8 extending beyond the end of the frame 1. The slide rail 8 refers to the track structure used to support and guide the movement of the pipe handling devices 5. Specifically, it can be implemented using linear guides or a rack and pinion transmission system, and its extension length can be adjusted according to actual needs. This structure allows the handling devices 5 to move along the slide rails 8 to the discharge area 9 outside the frame 1, preventing pipes from accumulating in the processing area. The discharge area 9 refers to the material storage space located outside the frame 1 and adjacent to the extension of the slide rail 8. Specifically, it can be implemented by setting up an independent platform, a conveyor belt system, or a loading / unloading rack. This area is physically separated from the processing area to prevent the cut pipe units 7 from interfering with equipment operation. In particular, when the two sets of pipe handling devices 5 move along the slide rails 8, they can cover the entire path from the loading rack 4 to the chuck 3 axis and the discharge area 9 outside the frame 1. During the unloading operation, the conveying device 5 clamps the cut pipe unit 7 and moves it along the slide rail 8 to the unloading area 9, which extends beyond the end of the frame 1, and then releases the pipe unit 7 into this area. The extension length of the slide rail 8 can be adjusted according to the length of the pipe. The independent setting of the unloading area 9 allows waste or finished pipes to be transferred directly to an external area for centralized processing or transshipment without being temporarily stored near the frame 1.

[0042] like Figures 1-3 As shown, a waste conveying track 10 is installed below the moving paths of multiple chucks 3 to receive and remove waste generated during laser cutting. The waste conveying track 10 refers to the material transfer channel located directly below the moving paths of the chucks 3. Specifically, it can be implemented using a track structure with a conveyor belt 1002, whose extension direction is parallel to the moving direction of the chucks 3. Through its targeted spatial layout, this track can directly receive waste falling from the chuck 3 area during cutting, preventing waste from scattering to other areas. The area below the moving paths of the chucks 3 refers to the track area covered by the chucks 3 as they move axially along the side of the frame 1. Specifically, the waste conveying track 10 can be installed and positioned at the bottom of the frame 1. This area allows waste to fall naturally into the track under gravity, without the need for additional guiding devices. In essence, the waste conveying track 10 is located below the moving paths of the chucks 3, and waste generated during cutting falls directly onto the track surface after detaching from the tubing. The waste conveyor track 10 transfers waste along a predetermined direction, such as from the cutting area to the outside of the equipment, via a continuously operating conveyor belt 1002. Waste is continuously removed during the conveying process, preventing accumulation inside the frame 1. The spatial correspondence between the chuck 3's movement path and the waste conveyor track 10 ensures that the waste collection area covers the chuck 3's working area, reducing the need for manual intervention.

[0043] In a further embodiment, the waste conveying track 10 includes a receiving track 1001, a conveyor belt 1002 circulated within the receiving track 1001, and a drive motor 1003 for driving the conveyor belt 1002. An elevated section 1004 is provided at the end of the receiving track 1001, and a waste outlet 1005 is provided within the elevated section 1004. The receiving track 1001 is the basic structure used to collect and guide waste, and can be implemented using a metal channel or steel frame structure. Its cross-sectional shape can be U-shaped to concentrate waste and prevent scattering. The conveyor belt 1002 is the circulating load-bearing component, and can be implemented using a rubber belt or metal chain plate structure. Anti-slip textures or baffles can be provided on the surface to increase the stability of waste transportation. The drive motor 1003 is the device that provides power to the conveyor belt 1002, and can be implemented using a geared motor or servo motor, connected to the conveyor belt 1002 via chain drive or gear drive. The raised section 1004 refers to the upward-sloping portion at the end of the receiving track 1001. It can be implemented using an arc-shaped transition section or a straight ramp structure, with an inclination angle ranging from 30° to 60°. This creates a height difference, raising the waste outlet 1005 above the ground, allowing a container to be placed below it to collect the waste. The waste outlet 1005 is the discharge port located at the end of the raised section 1004, and can be implemented using a rectangular opening or a funnel-shaped structure. The opening size can be adapted to a waste collection container or external conveying equipment. Specifically, the waste conveying track 10 receives the waste generated from laser cutting via the receiving track 1001. The conveyor belt 1002, driven by the drive motor 1003, circulates along the receiving track 1001, continuously conveying the waste towards the raised section 1004. When the waste material moves to the elevated section 1004 along the conveyor belt 1002, it is lifted by the inclined track and slides towards the waste outlet 1005, eventually leaving the equipment and entering the external collection system. The cooperation between the conveyor belt 1002 and the receiving track 1001 ensures that the waste material remains stable during transportation, avoiding accumulation along the way; the slope design of the elevated section 1004 reduces the load pressure on the conveyor belt 1002 by gravity-assisted discharge.

[0044] In one embodiment, this application further proposes that the pipe handling device 5 is a clamping robot. The clamping robot refers to an automated handling device with active clamping function, specifically implemented as a robotic arm structure with adjustable grippers. The spacing of the grippers can be dynamically adjusted according to the pipe length. The clamping force of the clamping robot can be controlled by a hydraulic or pneumatic system, specifically by using a proportional valve to adjust the clamping pressure to adapt to the gripping requirements of pipes of different diameters. The clamping robot applies controllable clamping force to both ends of the pipe through its grippers, maintaining the pipe's stable posture during handling. The adjustable gripper spacing allows the same robot to adapt to pipes of different lengths, eliminating the need for separate handling units for specific lengths. During loading and unloading operations, the clamping robot directly grips the pipe ends through clamping actions, replacing the passive support of the traditional support platform 504 and preventing the pipe from shifting due to its own weight. When loading, the gripping robot transfers the raw material pipe 6 from the loading rack 4 to the axis position of the chuck 3. When unloading, it transfers the cut pipe unit 7 to the unloading area 9, realizing a single device compatible with bidirectional handling functions.

[0045] In such Figure 4 and 5In another embodiment shown, the pipe handling device 5 includes a movable base 501, a rotating arm 502 mounted on the movable base 501, a lifting frame 503 rotatably mounted on the rotating arm 502, and a support platform 504 mounted on the lifting frame 503. The support platforms 504 on the two sets of pipe handling devices 5 cooperate to support the raw material pipe fittings 6 or pipe fitting units 7 for loading and unloading. The rotating arm 502 and the lifting frame 503 adapt to the orientation of loading and unloading through rotational movement. The lifting frame 503 is used for lifting and lowering to adapt to the height of loading and unloading. The movable base 501 refers to the base structure that supports the overall movement of the handling device 5. Specifically, it can be implemented using a ball screw mechanism driven by a servo motor. The distance between the two sets of handling devices 5 is adjusted by sliding along the slide rail 8 to adapt to the end support requirements of pipe fittings of different lengths. The rotating arm 502 refers to a rotatable robotic arm mounted on the movable base 501. Specifically, it can be driven by a worm gear transmission structure. Horizontal rotation changes the orientation of the support platform 504, allowing the pipe to adjust its entry and exit direction based on the relative position of the loading rack 4 and the frame 1 during transport. The lifting frame 503 refers to a vertical motion mechanism mounted on the rotating arm 502. Specifically, it can be driven by a hydraulic cylinder or an electric push rod. Vertical lifting adjusts the height of the support platform 504, ensuring precise alignment of the pipe with the axis of the chuck 3 or the storage position of the loading rack 4. The support platform 504 is a planar structure that directly contacts and supports the pipe. Specifically, it can be made of steel plate covered with anti-slip rubber, with adjustable baffles on both sides to limit lateral displacement of the pipe and maintain stability during transport. Specifically, after the movable base 501 moves along the length of the frame 1 to the target position, the rotating arm 502 drives the lifting frame 503 to rotate to an alignment with the loading rack 4 or the frame 1. The lifting frame 503 then moves vertically to a height matching the storage position or chuck 3, and the supporting platform 504 simultaneously lifts both ends of the pipe fitting to complete the clamping. During the handling process, the two sets of handling devices 5 maintain the horizontal posture of the pipe fitting through synchronous movement. The rotation angle of the rotating arm 502 can be adjusted in multiple positions according to the layout of the loading rack 4, and the stroke range of the lifting frame 503 covers the height difference between the storage position of the loading rack 4 and the axis of the chuck 3. After clamping the pipe fitting, the supporting platform 504 transports the pipe fitting to the processing area or unloading area 9 of the frame 1 through the translation of the movable base 501, realizing fully automated handling throughout the process.

[0046] Furthermore, auxiliary baffles 505 are provided on both sides of the support platform 504. The auxiliary baffles 505 are hinged to the sides of the support platform 504 and connected to the piston rod of the opening / closing cylinder 506. The auxiliary baffles 505 are plate-like structures installed on both sides of the support platform 504 to restrict the lateral movement of the pipe. They can be made of welded metal sheets, and their height can be adjusted according to the pipe diameter. This structure prevents slippage during handling by constraining the space on both sides of the pipe. The hinge refers to the structural form in which the auxiliary baffles 505 and the support platform 504 are connected by a rotating shaft. This can be achieved using a pin and bearing, allowing the baffles 505 to rotate around the shaft to complete the opening and closing action. The opening / closing cylinder 506 is the power element that drives the movement of the auxiliary baffles 505. It can be a double-acting cylinder, where the extension and retraction of the piston rod drives the baffles 505 to rotate around the hinge point, achieving synchronous opening and closing of the two baffles 505. Specifically, when the pipe is placed on the support platform 504, the opening and closing cylinder 506 drives the piston rod to retract, causing the auxiliary baffles 505 on both sides to rotate inward and close, forming a wrap-around restraint on the pipe. In the closed state, the inner wall of the baffle 505 remains in contact with the outer surface of the pipe, effectively suppressing lateral displacement caused by inertia or vibration during handling. After the loading and unloading operations are completed, the cylinder 506 drives the piston rod to extend, causing the baffle 505 to rotate outward and unfold, releasing the restraint on the pipe for subsequent processing. The hinged structure allows the opening and closing angle of the baffle 505 to automatically adjust according to the pipe diameter. For example, the unfolding range of the baffle 505 is smaller when handling large-diameter pipes and larger when handling small-diameter pipes, thus adapting to the restraint requirements of different pipe specifications.

[0047] In a further embodiment, a roller 507 is installed beside the support platform 504. The rolling direction of the roller 507 is consistent with the length direction of the raw material pipe 6 or pipe unit 7, and the upper end face of the roller 507 is slightly higher than the top surface of the support platform 504. The roller 507 is a cylindrical component that can rotate around its own axis. Specifically, it can be implemented using a metal roller with a wear-resistant coating and rolling bearings. Its rolling direction is parallel to the axial direction of the pipe, causing rolling friction between the pipe and the roller 507 during movement. The upper end face of the roller 507 being slightly higher than the top surface of the support platform 504 means that there is a slight height difference between the top of the roller 507 and the surface of the support platform 504. This can be achieved by adjusting the height of the roller 507 mounting base or by using adjustable pads. This height difference ensures that the main body of the pipe is supported by the roller 507 while its edge contacts the support platform 504. Specifically, when the pipe is clamped by the handling device 5 and placed on the support platform 504, the axial direction of the pipe remains parallel to the rolling direction of the roller 507. Since the surface of the roller 507 can rotate freely, rolling occurs between the pipe and the roller 507 as the pipe moves along its length, significantly reducing resistance compared to the sliding friction of a traditional fixed support surface. The design of the roller 507 being slightly higher than the support platform 504 allows the main body of the pipe to be supported by the roller 507 and roll freely. This structure eliminates the need to adjust the limiting mechanism for pipes of different lengths; stable support and guidance are achieved solely through the height difference between the roller 507 and the support platform 504.

[0048] Furthermore, the pipe handling device 5 includes a clamping device, which is disposed within the enclosure plate 511. The clamping device includes two sets of interconnected movable seats 508 that can move closer or further apart, a lifting cylinder 509 disposed on the movable seats 508, and a clamping plate 510 disposed on the output end of the lifting cylinder 509. The lifting cylinder 509 drives the clamping plate 510 to extend out of the enclosure plate 511 or retract into the enclosure plate 511. The movable seat 508 refers to a load-bearing structure that moves horizontally along a guide rail. Specifically, it can be implemented using a servo motor-driven lead screw transmission. The clamping distance is adjusted by the relative position of the two sets of movable seats 508, thereby adapting to pipes of different lengths. The lifting cylinder 509 is a power element that moves vertically. Specifically, it can be a double-acting cylinder. The height of the clamping plate 510 is adjusted by the cylinder stroke, allowing it to lower during pipe loading and unloading to avoid obstruction. When fixing the pipe fitting, the clamping plate 510 can be raised to align the clamping position with the pipe fitting's axis. The clamping plate 510 is the clamping component that contacts the end of the pipe fitting. It can be a curved plate structure with anti-slip texture. Clamping force is applied by the cylinder thrust to ensure the pipe fitting remains stable during handling. Specifically, the moving seat 508 moves synchronously in opposite directions on the guide rail, adjusting the spacing of the clamping plates 510 according to the pipe fitting length. The lifting cylinder 509 drives the clamping plates 510 to rise or fall, adjusting between avoiding obstruction and clamping the pipe fitting. After the clamping plates 510 close, friction fixes the end of the pipe fitting, and the moving seat 508 moves the entire pipe fitting to the target position. During handling, the dynamic adjustment of clamping spacing and height prevents pipes from shifting or slipping, ensuring that pipes of different lengths remain stable during loading and unloading.

[0049] The loading and unloading directions of the aforementioned heavy-duty laser tube cutting machine are not explicitly specified, such as... Figure 1 and 2 As shown, the main structure of the heavy-duty laser tube cutting machine, such as the frame 1, laser tube cutting assembly 2, chuck 3, and loading rack 4, is located on the left side, while the unloading area 9 is located on the right side of the frame. However, as... Figure 6 and 7 In another embodiment shown, the main structure of the heavy-duty laser tube cutting machine, such as the frame 1, laser tube cutting assembly 2, chuck 3, and loading rack 4, can be located on the right side, while the unloading area 9 and its unloading rack 91 are located on the left side, thus achieving right-side unloading. Based on the adjustable loading and unloading direction of the heavy-duty laser tube cutting machine, it can adapt to the layout requirements of the equipment location. Furthermore, in... Figure 6 and 7In the illustrated embodiment, a receiving box 110 for receiving tail waste is provided on the end of the frame away from the unloading area 9, and a guide ramp 111 for guiding the tail waste into the receiving box 110. During processing, the tail waste remaining after laser cutting of the pipe is generally held by the chuck at the very end. After the chuck is released, it can be guided into the receiving box 110 by the guide ramp 111, thus completing the recycling and receiving of the tail waste. The receiving box 110 is located at the end of the waste conveying track 10. The receiving box 110 and the waste conveying track 10 can be combined to receive tail waste and the waste obtained from cutting, respectively. The guide ramp 111 is provided below or at the end of the chuck 3's moving path. During the unloading of tail waste, the chuck at the end only needs to move to the side of the guide ramp 111, without needing to move to the end of the frame. This design avoids excessive waste material at the tail end from causing the waste conveying track 10 to jam, reduces the movement path length of the chuck, and simplifies the social security structure.

[0050] As can be seen from the above, the heavy-duty laser tube cutting machine and its tube handling device 5 and waste disposal system provided in this application realize the automatic loading and unloading of tubes of various specifications through two sets of adjustable spacing tube handling devices 5. Combined with the mobile chuck 3 and integrated waste disposal system, it effectively solves the technical problems of large footprint, low loading and unloading efficiency and waste accumulation of traditional equipment. It has the advantages of improving equipment integration, enhancing loading and unloading efficiency and optimizing waste disposal capacity.
