Furthermore, all connections / linkages mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0017] In the traditional field of pipe cutting and processing, laser cutting generates intense laser radiation. If operators are directly exposed to this environment, it can cause serious damage to their eyes and skin. At the same time, cutting produces a large amount of spatter, such as molten metal particles. This spatter may injure operators and also pollute equipment components and the surrounding environment.

[0018] Therefore, this invention proposes an automatic loading and unloading beveling and cutting pipe machine, referring to... Figures 1-7 The system includes a frame 100, a gantry 110 mounted on the frame 100, a laser cutting assembly 200 mounted on the gantry 110 and capable of reciprocating along the front-back and up-down directions of the gantry 110, a rear chuck assembly 210 and a front chuck assembly 220 mounted on the frame 100 and capable of reciprocating along the left-right direction of the frame 100, a receiving assembly 230 located downstream of the frame 100, multiple side seats 120 located on the front side of the frame 100, multiple loading assemblies 240 located on the side seats 120, and multiple follow-up support assemblies 250. The gantry 110 is located on the outer... The assembly is surrounded by a first protective component 300, which includes a housing 310 for housing the laser cutting assembly 200. The housing 310 has first clearance holes 311 on its left and right sides for the rear chuck assembly 210 and the front chuck assembly 220 to pass through. The follow-up support assembly 250 is surrounded by a second protective component 400. The loading assembly 240 is surrounded by a third protective component 500. The rear chuck assembly 210 is surrounded by a fourth protective component 600. The front chuck assembly 220 is surrounded by a fifth protective component 700.

[0019] The frame 100 provides basic support; the gantry 110 is fixed on the frame 100, and the laser cutting assembly 200 can move along the front-to-back and up-and-down directions of the gantry 110 via a slide rail or lead screw mechanism to achieve multi-dimensional cutting; the rear chuck assembly 210 and the front chuck assembly 220 can move along the left-to-right direction of the frame 100 via linear guide rails for clamping and feeding pipes; the receiving assembly 230 is located downstream of the frame 100 for receiving the cut pipes; the side seat 120 is fixed on the front side of the frame 100, and the loading assembly 240 is mounted on the side seat 120 for... The system features automatic feeding; a follow-up support assembly 250 is mounted on the frame 100 to support the pipe during cutting; the housing 310 of the first protective assembly 300 surrounds the gantry 110, forming a closed space that encloses the laser cutting assembly 200 and the front chuck assembly 220; a first clearance hole 311 allows the rear chuck assembly 210 and the front chuck assembly 220 to extend into or out of the housing 310; the cutting follow-up support assembly 250, the feeding assembly 240, and the rear chuck assembly 210 are independently protected by the second, third, and fourth protective assemblies 600, respectively. By setting independent protective assemblies for key working components, the laser cutting area is effectively isolated from the operator, preventing laser radiation, spatter, and exhaust gases from causing harm to personnel, while also protecting equipment components from external interference and damage.

[0020] In practical applications, the pipe to be cut is fed into the upstream storage area of ​​the feeding assembly 240. The feeding assembly 240 then begins operation, gradually conveying the pipes one by one to multiple follower support assemblies 250 through its own transmission mechanism. The follower support assemblies 250 lift the pipes according to their size and position, placing them coaxial with the rear chuck assembly 210 and the front chuck assembly 220. The rear chuck assembly 210 clamps the pipes and pushes them towards the laser cutting assembly 200 along the left and right directions of the frame 100 via a linear guide rail, thus achieving cutting feed. During the cutting process, the front chuck assembly 220, together with the rear chuck assembly 210, clamps the pipes to ensure their stability. The receiving assembly 230 provides support for the pipes above it during the cutting process. Because the housing 310 of the first protective component 300 surrounds the gantry 110, forming a closed space, it encloses the laser cutting component 200 and part of the front chuck component 220. The first clearance hole 311 allows the rear chuck component 210 and the front chuck component 220 to extend into or out of the housing 310, enabling the pipe to be cut in a closed cutting environment, effectively preventing laser radiation, spatter, and exhaust gas from harming personnel. When there is remaining tail material in the pipe, the rear chuck component 210 releases its grip on the tail material, and the front chuck component 220 holds the remaining tail material alone, sending the part of the tail material to be cut below the laser cutting component 200 for cutting, reducing the distance between the tail material and the laser cutting component 200, and reducing the amount of tail material. After cutting, the tail material / short material is discharged between the laser cutting component 200 and the receiving component 230. A receiving box 822 can be placed at the tail material / short material discharge point to receive the tail material / short material, eliminating the need for conveying via the receiving component 230. The cut pipes fall onto the receiving assembly 230 under gravity. When unloading is required, the receiving assembly 230 tilts, causing the cut pipe segments to roll downstream under gravity, thus achieving automatic unloading. At this time, the pipes can be collected and stacked with the assistance of a mechanical crane or manual labor. Subsequently, the system resets, and the feeding assembly 240 begins to push the next pipe, entering the next work cycle.

[0021] Cutting debris and fumes may escape through the clearance holes, exposing operators to these hazardous substances. Therefore, in one embodiment, the first protective assembly 300 further includes two protective covers 320, each covering one of the first clearance holes 311. Each protective cover 320 includes a cover body 321, clips 322, and a protective curtain 323. The two cover bodies 321 are respectively located at both ends of the housing 310, and the two clips 322 are respectively located on the side of the two cover bodies 321 away from the housing 310. The upper parts of the two protective curtains 323 are clamped between the clips 322 and the cover bodies 321 by fasteners. The protective covers 320 are fixed around the first clearance holes 311 of the housing 310 by bolts or welding. The cover 321 is a metal plate, the clamping plate 322 is a strip-shaped pressure plate, and the protective curtain 323 is made of rubber or canvas. The upper edge of the protective curtain 323 is clamped between the clamping plate 322 and the cover 321 by screws or other fasteners. The protective curtain 323 hangs down to cover the first clearance hole 311 and deforms as the chuck assembly moves. The protective cover 320 can dynamically cover the first clearance hole 311, adapting to the reciprocating movement of the rear chuck assembly 210 and the front chuck assembly 220, preventing cutting debris and smoke from escaping from the clearance hole, while reducing friction and interference during the movement of the chuck assembly, and improving the continuity and reliability of protection.

[0022] If an emergency adjustment or maintenance is required during the cutting process, the machine must be stopped, which interrupts the production process, leading to a significant decrease in production efficiency and an increase in production costs. Therefore, in one embodiment, the first protective component 300 further includes an operating hole 312, a slide rod 330, a slide block 331, and a movable door 332. The operating hole 312 is located on the front side wall of the housing 310 and communicates with the internal space of the housing 310. The slide block 331 is fixed to the housing 310. The slide rod 330 is located on the side of the movable door 332 near the housing 310 and is slidably connected to the slide block 331. The movable door 332 is used to open or close the operating hole 312. The operating hole 312 is located on the front side wall of the housing 310, facilitating access for the operator's hands or tools. The slide block 331, a guide rail or slider, is fixed to the housing 310. The slide rod 330, a rod-like structure, is fixed to the back of the sliding door 332 and works with the slide block 331 to slide. The sliding door 332, a plate-like structure, slides on the slide block 331 via the slide rod 330 to open or close the operating hole 312. The operating hole 312 allows operators to perform emergency adjustments or maintenance without shutting down the machine. The sliding door 332 provides a flexible opening and closing mechanism, ensuring it remains closed during non-operational periods to maintain its protective effect and improve equipment availability and safety. The sliding structure ensures smooth and stable opening and closing of the sliding door 332, reducing space occupation and effortless operation. It also ensures that the sliding door 332 is not easily deformed or jammed during frequent use, extending its service life.

[0023] Dust, debris, and other foreign objects from the outside can easily enter the area where the follower support assembly 250 is located. These foreign objects can become trapped between the moving parts of the assembly, increasing the coefficient of friction and accelerating the wear rate of the various parts of the follower support assembly 250 during frequent operation. Therefore, in one embodiment, the second protective assembly 400 includes a first protective plate 410 and a second protective plate 420. One end of the first protective plate 410 is fixedly connected to the corresponding side seat 120, and the other end of the first protective plate 410 is fixedly connected to one end of the second protective plate 420 by bolts. The other end of the second protective plate 420 is fixedly connected to the front side wall of the frame 100. The first protective plate 410, the second protective plate 420, the side seat 120, and the frame 100 enclose a first installation space for installing the follower support assembly 250. The first protective plate 410 and the second protective plate 420 of the second protective assembly 400 are metal plates, which are fixed to the side seat 120 and the frame 100 by welding or bolts, respectively, forming a U-shaped or L-shaped enclosure structure. The connection between the first protective plate 410 and the second protective plate 420 and the side seat 120 and the frame 100 forms a first installation space for installing the follower support assembly 250, creating a relatively enclosed space that physically blocks external foreign objects, preventing dust, debris and other foreign objects from entering the area where the follower support assembly 250 is located, reducing component wear caused by foreign object intrusion, and effectively extending the service life of the follower support assembly 250. The first protective plate 410 and the second protective plate 420 are fixed to the side seat 120 and the frame 100 respectively by welding or bolting. This connection method not only ensures the firmness of the protective assembly installation, but also facilitates the relatively convenient disassembly of the protective plate when it is necessary to inspect, maintain or replace the follower support assembly 250, and enter the installation space to carry out the corresponding work.

[0024] During the loading process, the pipes may deviate from their original conveying path due to external forces, potentially preventing them from accurately entering subsequent processing positions. Therefore, in one embodiment, the third protective component 500 includes a protective frame 510 and two protective nets 520. The protective frame 510 is disposed on one side of the loading component 240 and includes a baffle 511 and two first uprights 512. The two ends of the baffle 511 are respectively connected and fixed to the two first uprights 512. The height of the baffle 511 matches the height of the loading component 240, preventing displacement of the pipes placed in the loading component 240 in the vertical direction of the transport direction. The two protective nets 520 are respectively disposed on the left and right sides of the loading component 240. Each protective net 520 includes at least two second uprights 521 and multiple horizontal bars 522, which are spaced apart vertically. The two ends of each horizontal bar 522 are respectively connected and fixed to the adjacent second upright 521. The baffle 511 of the protective frame 510 is a vertical plate structure, fixed to the ground or frame 100 by the first column 512, located on one side of the conveying direction of the feeding assembly 240. It acts as a barrier in the vertical direction of the conveying direction, preventing unnecessary displacement of the pipe to one side and ensuring that the pipe moves smoothly along the conveying direction of the feeding assembly 240, maintaining the orderliness of the feeding. The second column 521 of the protective net 520 is a vertical bar, and the horizontal bar 522 is a horizontal or inclined bar, connected by welding or fasteners to form a grid-like barrier, located on the left and right sides of the feeding assembly 240. The third protective assembly 500 restricts the movement range of the pipe during the feeding process through the baffle 511 and the protective net 520, preventing the pipe from rolling, falling or colliding, ensuring the feeding sequence and safety, and reducing the risk of material loss and personnel injury.

[0025] Foreign objects such as cutting debris and dust can easily enter the moving device and chuck drive device, accelerating component wear. Therefore, in one embodiment, the fourth protective component 600 includes a first housing 610, a second housing 620, and a cover plate 630. The first housing 610 is disposed on the rear chuck assembly 210, and the first housing 610 encloses a second mounting space for mounting the moving device of the rear chuck assembly 210. The second housing 620 is disposed on the rear chuck assembly 210. The cover plate 630 is detachably disposed on the second housing 620 by fasteners. The second housing 620 and the cover plate 630 enclose a third mounting space for mounting the chuck drive device of the rear chuck assembly 210. The second housing 620 has a second clearance hole 621 on the side near the front chuck assembly 220 for the clamping device of the rear chuck assembly 210 to extend out. The cover plate 630 has a heat dissipation hole 631. The first housing 610 and the second housing 620 are metal covers, which are fixed to the base of the rear chuck assembly 210 by bolts; the moving device (such as a motor and guide rail) is installed in the second mounting space, and the chuck driving device (such as a hydraulic or electric actuator) is installed in the third mounting space; the cover plate 630 can be opened for maintenance, the second clearance hole 621 allows the chuck's jaws to extend and clamp the tubing, and the heat dissipation hole 631 promotes heat dissipation of the actuator; the fourth protective component 600 protects the movement and driving device of the rear chuck assembly 210 from the intrusion of cutting debris and dust, reduces component wear and failure, the heat dissipation hole 631 ensures good heat dissipation of the driving device, extends the equipment life, and at the same time, the removable cover plate 630 facilitates maintenance and repair.

[0026] Foreign objects such as cutting debris and dust can easily enter the moving device and chuck drive device, accelerating component wear. Therefore, in one embodiment, the fifth protective component 700 includes a third housing 710 and a fourth housing 720. The third housing 710 is disposed on the front chuck assembly 220, and the third housing 710 encloses a fourth mounting space for mounting the moving device of the front chuck assembly 220. The fourth housing 720 is disposed on the front chuck assembly 220, and the fourth housing 720 encloses a fifth mounting space for mounting the chuck drive device of the front chuck assembly 220. The fourth housing 720 is provided with a third clearance hole 721 for the tubing to extend into the clamping device of the rear chuck assembly 210. The third housing 710 and the fourth housing 720 are metal covers and are fixed to the base of the front chuck assembly 220 by bolts. The moving mechanism (such as a motor and guide rail) of the front chuck assembly 220 is installed in the fourth mounting space, and the chuck drive mechanism (such as a hydraulic or electric actuator) of the front chuck assembly 220 is installed in the fifth mounting space. The third clearance hole 721 allows the tubing to extend into the jaws of the front chuck for securing the tubing. The fifth protective assembly 700 protects the moving and drive mechanism of the front chuck assembly 220 from the intrusion of cutting debris and dust, reducing component wear and malfunctions. The heat dissipation hole 631 ensures good heat dissipation of the drive mechanism, extending the equipment life.

[0027] The large amount of harmful fumes and exhaust gases generated during cutting will fill the work area, significantly increasing the concentration of harmful substances in the air. Prolonged exposure to such an environment can easily lead to the inhalation of harmful components and health problems for operators. Therefore, in one embodiment, a ventilation assembly 800 is also included. The ventilation assembly 800 includes a ventilation pipe 810, a baffle 820, and a ventilation device. The ventilation pipe 810 is mounted on the gantry 110 and located below the laser cutting assembly 200. The air inlet of the ventilation pipe 810 is located inside the housing 310 and communicates with the internal space of the housing 310. The air outlet of the ventilation pipe 810 is connected to the ventilation device. The baffle 820 is mounted on the gantry 110 and covers the air inlet of the ventilation pipe 810. The baffle 820 has an exhaust hole 821. The ventilation pipe 810 is a metal or plastic pipe, fixed to the gantry 110, with its air inlet facing the cutting area. The baffle 820 has a mesh or plate structure, covering the air inlet of the exhaust pipe 810, and the exhaust holes 821 are multiple small holes or slits. The exhaust device (such as a fan) is connected to the air outlet of the exhaust pipe 810 through a pipe, generating negative pressure to draw out smoke and mist. The exhaust assembly 800 effectively removes smoke and exhaust gas generated during laser cutting, improving the working environment and reducing health hazards; the baffle 820 prevents short pipes or tail material from directly impacting the exhaust pipe 810 when falling, avoiding pipe damage, and at the same time guides the airflow for concentrated suction, improving exhaust efficiency.
