Description

Technical Field

[0001] This application relates to the technical field of pipe cutting and welding equipment, and in particular to digital pipe cutting and welding equipment based on BIM models. Background Technology

[0002] In the fields of construction, chemical engineering, and municipal engineering, pipelines are core components, and their processing quality and efficiency directly affect project progress and safety. Currently, pipeline cutting and welding equipment on the market can be mainly divided into three categories: First, manually operated equipment, such as handheld cutting machines and small welding machines, rely on manual tool handling and are only suitable for small-batch, simple-specification pipeline processing; second, semi-automated equipment, which mechanizes some processes through a fixed frame and basic power components (such as pneumatic clamps), but key components such as the cutting head still require manual adjustment; and third, traditional fixed automated equipment, mostly dedicated models, relying on preset programs to drive a single power mechanism to complete processing, commonly found in large-scale standardized pipeline production.

[0003] Traditional equipment lacks multi-dimensional collaborative adjustment capabilities, requiring manual operation step-by-step for processes such as clamping, angle adjustment, and feeding. When dealing with pipes with complex bends, operators must repeatedly adjust positions and manually calibrate, extending processing cycles and increasing the risk of accuracy deviations due to operational errors. In batch processing, manual pipe transfer or parameter resetting is required after each process, hindering continuous production and resulting in low equipment utilization. Furthermore, insufficient automation makes processing highly dependent on skilled workers, requiring significant investment in training, and the instability of manual operation easily leads to batch-related quality issues.

[0004] Traditional cutting and welding operations are fraught with hazards such as sparks, high-temperature radiation, and harmful gases, with risks even greater when working at heights or in confined spaces. Traditional pipe processing equipment requires frequent personnel involvement in pipe loading, unloading, and repositioning, making it impossible to effectively isolate hazardous sources. Personnel in close contact with the processing area are prone to burns, electric shocks, and mechanical injuries. Summary of the Invention

[0005] To achieve efficient automated processing and safe operation, this application provides a BIM-based digital pipe cutting and welding equipment.

[0006] The BIM model-based digital pipe cutting and welding equipment provided in this application adopts the following technical solution: The BIM-based digital pipe cutting and welding equipment includes a processing base and a cutting assembly and a welding robot mounted on the processing base. The processing base includes a base box and a worktable. The worktable is fixedly mounted on the upper surface of the base box. A rotating seat is mounted at the center of the upper surface of the worktable, and an angle motor that drives the rotating seat to rotate is fixedly mounted on the worktable. A control ring frame is fitted on the outer surface of the rotating seat and is fixedly connected to the rotating seat. A first lifting frame and a second lifting frame are slidably mounted at both ends of the control ring frame, and an electric cylinder one for adjusting the height of the first lifting frame and an electric cylinder two for adjusting the height of the second lifting frame are fixedly mounted on the control ring frame. An angle adjustment assembly is mounted on the head of the first lifting frame, and a clamping and feeding assembly is installed in the angle adjustment assembly. An auxiliary guide shell is rotatably mounted on the head of the second lifting frame.

[0007] By adopting the above technical solution, the processing base ensures the equipment can be stably placed on the ground for use. The cutting components and welding robots are fixedly installed on the processing base, allowing them to flexibly perform cutting and welding according to the program. This, combined with adjustable rotation, lifting, and angle mechanisms, enables multi-degree-of-freedom positioning and processing of the pipeline. Integration with BIM model data allows for the acquisition of precise pipeline geometry information in advance, achieving accurate positioning and automated processing, significantly improving processing efficiency and accuracy. The angle motor and rotating seat facilitate horizontal rotation adjustment during processing. The first and second lifting frames are slidably installed at both ends of the control ring frame, allowing for control of the angle adjustment components and auxiliary guide shell height via electric cylinders one and two. The angle adjustment components clamp one end of the pipeline and adjust its elevation angle. When the pipeline is long, the auxiliary guide shell provides additional support to one end, increasing pipeline stability during processing.

[0008] Optionally, the control ring frame includes a central ring seat, a transverse support rod, and an outer ring frame. The central ring seat is sleeved and fixed on the outer side of the rotating seat. The outer ring frame is coaxially installed outside the central ring seat. The transverse support rod is fixedly installed between the outer ring frame and the central ring seat, and both ends of the transverse support rod are fixedly connected to the outer ring frame and the central ring seat, respectively. The two ends of the outer ring frame are respectively provided with guide shell one and guide shell two for sliding installation of the first lifting frame and the second lifting frame.

[0009] By adopting the above technical solution, a stable and guiding frame is constructed by designing the control ring frame as a combination of a central ring seat, transverse support rods, and an outer ring frame. The central ring seat is designed to fit snugly onto the rotating seat, allowing for synchronous rotation and adjustment during use. The transverse support rods connect the central ring seat and the outer ring frame, ensuring their synchronous rotation. The guide shell on the outer ring frame provides a precise sliding path for the first and second lifting frames, ensuring the stability and repeatability of the lifting frames, laying the foundation for subsequent precision cutting and welding.

[0010] Optionally, the first lifting frame includes a longitudinal shell, a diagonal brace, and a control box door. The longitudinal shell is slidably installed in a guide shell. The diagonal brace is symmetrically installed at the head of the longitudinal shell, and the lower end of the diagonal brace is fixedly connected to the longitudinal shell. A positioning ring seat is also fixedly installed at the head of the diagonal brace. The control box door is installed on the longitudinal shell, and one side of the control box door is rotatably connected to the longitudinal shell.

[0011] By adopting the above technical solution, the first lifting frame is designed with a structure consisting of a longitudinal shell, a diagonal brace, and a control box door. The longitudinal shell ensures the stability of lifting and facilitates the internal placement of corresponding control components, enabling convenient control of equipment such as the upper motor. The design of the control box door facilitates the maintenance of internal wiring and components. The diagonal brace and positioning ring provide a reliable connection between the head of the first lifting frame and the subsequent angle adjustment assembly, ensuring the stability of force transmission and the accuracy of angle adjustment.

[0012] Optionally, the second lifting frame includes a sliding rod and a concave seat. The sliding rod is slidably installed in the second guide shell, and the concave seat is fixedly installed at the head of the sliding rod. The concave seat has positioning shaft holes on both sides for the auxiliary guide shell to be rotated and installed.

[0013] By adopting the above technical solution, the second lifting frame is designed with a sliding rod and a concave seat in combination. This ensures smooth lifting during use through the sliding rod, while the concave seat provides a stable mounting base for the auxiliary guide shell and has reserved a positioning shaft hole to facilitate the rotation and installation of the auxiliary guide shell. This plays a key role in the positioning and guidance of the auxiliary pipeline.

[0014] Optionally, the angle adjustment assembly includes a flip shell assembly and an angle driving component for driving the flip shell assembly to rotate. The flip shell assembly has an outer shaft fixedly installed on both sides, and the outer shaft is rotatably installed in a positioning ring seat. The angle driving component is fixedly installed on the outer side of the longitudinal shell.

[0015] By adopting the above technical solution, the tilting shell assembly is connected to the positioning ring seat of the first lifting frame via an external shaft, and the tilting shell assembly achieves precise angular rotation via an angle drive component. This allows the equipment to adaptively adjust according to the bending angle of the pipe in the BIM model, enabling cutting and welding of pipes at any angle.

[0016] Optionally, the flipping shell assembly includes a feeding shell and a transmission shell. The feeding shell is fixedly installed at one end of the transmission shell, and guide grooves are provided on both sides of the feeding shell and the transmission shell.

[0017] By adopting the above technical solution, the internal structure of the tilting shell assembly has been further refined. The feed shell provides the inlet for the pipeline, while the transmission shell integrates the drive and control mechanisms. The guide grooves on both sides provide a stable motion trajectory for the clamping and feeding components, ensuring their precise movement within the tilting shell assembly.

[0018] Optionally, the angle driving component includes a side motor and a drive gear. The side motor is fixedly mounted on the outer side surface of the longitudinal housing, and the drive gear is sleeved and fixed on the output shaft of the side motor. A driven gear that meshes with the drive gear is fixedly mounted on the outer end of the outer shaft.

[0019] By adopting the above technical solution, the angle drive component is designed as a structure in which a side motor and a drive gear cooperate. This ensures that during use, the side motor drives the driven gear on the outer shaft to rotate via the drive gear, thereby driving the tilting housing assembly to adjust the angle. The gear transmission method features a compact structure, high transmission accuracy, and rapid response, enabling precise angle control.

[0020] Optionally, the clamping and feeding assembly includes a clamping roller frame, an external slide, and a control component. Two sets of external slides are provided and symmetrically installed on the tilting shell assembly. The external slides are slidably installed in the guide groove, and the lower end of the external slide extends into the tilting shell assembly through the guide groove. The clamping roller frame is fixedly installed on the lower end of the external slide. The control component is installed on the tilting shell assembly and is used to adjust the distance between the two sets of external slides.

[0021] By adopting the above technical solution, the clamping and feeding assembly is designed as a structure that combines a clamping roller frame, an external sliding frame, and a control component. During use, two sets of symmetrical external sliding frames move in guide grooves, driving the clamping roller frame to clamp and feed the pipe. The control component can precisely adjust the distance between the two sets of external sliding frames, thereby achieving adaptive clamping of pipes of different diameters. This ensures the stability and feeding accuracy of the pipe during cutting or welding.

[0022] Optionally, the clamping roller frame includes a wheel seat, a drive clamping roller, and a feeding clamping roller. The drive clamping roller is rotatably mounted on the head of the wheel seat, and a bottom motor for driving the drive clamping roller to rotate is fixedly mounted on the lower end of the wheel seat. The drive clamping roller is uniformly rotated in the wheel seat.

[0023] By adopting the above technical solution, the structure of the clamping roller frame has been further refined. The cooperation between the drive clamping roller and the feeding clamping roller enables stable clamping of the pipe, and the rotation of the drive clamping roller achieves precise feeding of the pipe. The bottom motor directly drives the clamping roller, resulting in high transmission efficiency and precise control. The drive clamping roller and the feeding clamping roller can be coated with wear-resistant rubber or polyurethane to provide good friction and protection for the pipe surface.

[0024] Optionally, a connecting screw tube is fixedly installed in the middle of the external carriage. The control component includes a top motor and a double-ended screw that cooperates with the connecting screw tube. The two ends of the double-ended screw are rotatably installed on the upper end of the transmission housing. The top motor is fixedly installed on the upper end face of the transmission housing, and the top motor is connected to the double-ended screw through a transmission belt.

[0025] By adopting the above technical solution, the top motor drives the double-headed screw to rotate via a transmission belt. The double-headed screw, through a connecting solenoid, drives two sets of external sliding frames to move inward or outward, thereby achieving adaptive clamping of the pipe diameter and precise control of the pipe spacing. This achieves precise control of the clamping torque, ensuring the stability and reliability of the clamping process.

[0026] In summary, this application includes at least one of the following beneficial technical effects: This application utilizes multiple sets of motors and electric cylinders to flexibly clamp, adjust the angle, and automatically feed the pipes to be processed, achieving automated and digitalized pipe cutting and welding operations, eliminating significant manual intervention, and greatly shortening the processing cycle. Data linkage with the BIM model allows the equipment to directly obtain precise processing instructions, eliminating the need for complex on-site measurements and manual calculations, thus improving efficiency from the source. Based on the precise geometric information of the BIM model, the equipment can accurately position, cut, and weld pipes. Automated processing reduces reliance on skilled workers, lowering labor costs. Precise cutting and welding reduce material waste, avoiding waste caused by human error. Simultaneously, the equipment enables continuous production, improving equipment utilization.

[0027] This equipment also improves operational safety. Traditional pipe cutting and welding operations pose significant safety risks, such as sparks and working at heights. It automates most of the process, requiring operators to focus on monitoring and simple loading and unloading, greatly reducing the probability of personnel exposure to hazards and enhancing operational safety. Furthermore, its flexible, multi-degree-of-freedom adjustment capabilities allow it to easily handle various complex pipeline needs, enabling precise processing of pipes of any shape, thus overcoming the shortcomings of traditional stationary equipment.

[0040] This application discloses a digital pipe cutting and welding device based on a BIM model.

The processing base 1 includes a seat box 11 and a worktable 12. The worktable 12 is fixedly mounted on the upper surface of the seat box 11. A rotating seat 2 is mounted at the center of the upper surface of the worktable 12, and an angle motor that drives the rotating seat 2 to rotate is fixedly mounted on the worktable 12. A control ring frame 3 is fitted on the outer surface of the rotating seat 2 and is fixedly connected to the rotating seat 2. A first lifting frame 4 and a second lifting frame 5 are slidably mounted on both ends of the control ring frame 3, and an electric cylinder 301 for adjusting the height of the first lifting frame 4 and an electric cylinder 302 for adjusting the height of the second lifting frame 5 are fixedly mounted on the control ring frame 3. An angle adjustment component 6 is mounted on the head of the first lifting frame 4, and a clamping and feeding component 7 is mounted in the angle adjustment component 6. An auxiliary guide shell 8 is rotatably mounted on the head of the second lifting frame 5. The processing base 1 ensures the equipment can be stably placed on the ground for use. Cutting components and welding robots are fixedly installed on the processing base 1, allowing for flexible cutting and welding operations according to the program. This, combined with adjustable rotation, lifting, and angle mechanisms, enables multi-degree-of-freedom positioning and processing of the pipeline. Integration with BIM model data allows for the acquisition of precise pipeline geometry information in advance, achieving accurate positioning and automated processing, significantly improving processing efficiency and precision. The angle motor and rotating base 2 facilitate horizontal rotation adjustment during processing. The first lifting frame 4 and the second lifting frame 5 are slidably installed at both ends of the control ring frame 3, allowing for control of the angle adjustment component 6 and the auxiliary guide shell 8's height via electric cylinders 301 and 302. The angle adjustment component 6 clamps one end of the pipeline and adjusts its elevation angle. For longer pipelines, the auxiliary guide shell 8 provides additional support to one end, increasing pipeline stability during processing.

[0042] Reference Figure 3 and Figure 4The control ring frame 3 includes a central ring seat 31, a transverse support rod 32, and an outer ring frame 33. The central ring seat 31 is sleeved and fixed on the outer surface of the rotating seat 2. The outer ring frame 33 is coaxially installed outside the central ring seat 31. The transverse support rod 32 is fixedly installed between the outer ring frame 33 and the central ring seat 31, and its two ends are fixedly connected to the outer ring frame 33 and the central ring seat 31, respectively. The two ends of the outer ring frame 33 are respectively provided with guide shell 1 331 and guide shell 2 332 for sliding installation of the first lifting frame 4 and the second lifting frame 5. By designing the control ring frame 3 as a combination of the central ring seat 31, the transverse support rod 32, and the outer ring frame 33, a stable frame with guiding function is constructed. The central ring seat 31 is set to ensure that it is sleeved on the rotating seat 2 and can rotate and be adjusted synchronously with the rotating seat 2 during use. The transverse support rod 32 connects the central ring seat 31 and the outer ring frame 33, thus ensuring that the central ring seat 31 and the outer ring frame 33 rotate synchronously. The guide shell on the outer ring frame 33 provides a precise sliding path for the first and second lifting frames 5, ensuring the stability and repeatability of the lifting frames and laying the foundation for subsequent precision cutting and welding.

[0043] Reference Figure 4 and Figure 5 The first lifting frame 4 includes a longitudinal shell 41, a diagonal brace 42, and a control box door 43. The longitudinal shell 41 is slidably installed in the guide shell 331.

The control box door 43 is installed on the longitudinal shell 41, and one side of the control box door 43 is rotatably connected to the longitudinal shell 41. By designing the first lifting frame 4 into a structure in which the longitudinal shell 41, the diagonal brace 42, and the control box door 43 cooperate, the longitudinal shell 41 ensures the stability of lifting and facilitating the internal installation of corresponding control components, thus facilitating the control of equipment such as the upper motor. The design of the control box door 43 facilitates the maintenance of internal wiring and components. The diagonal brace 42 and the positioning ring seat 421 provide a reliable connection between the head of the first lifting frame 4 and the subsequent angle adjustment assembly 6, ensuring the stability of force transmission and the accuracy of angle adjustment. The second lifting frame 5 includes a sliding rod portion 51 and a concave seat 52. The sliding rod portion 51 is slidably installed in the guide housing 332, and the concave seat 52 is fixedly installed on the head of the sliding rod portion 51. Positioning shaft holes 521 are provided on both sides of the concave seat 52 for the rotatable installation of the auxiliary guide housing 8. By designing the second lifting frame 5 with a structure in which the sliding rod portion 51 and the concave seat 52 cooperate, smooth lifting is ensured during use through the sliding rod portion 51. The concave seat 52 provides a stable mounting base for the auxiliary guide housing 8 and has reserved positioning shaft holes 521 to facilitate the rotatable installation of the auxiliary guide housing 8. This plays a crucial role in the positioning and guiding of the auxiliary pipeline.

[0044] Reference Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 The angle adjustment assembly 6 includes a tilting shell assembly 61 and an angle drive component 62 that drives the tilting shell assembly 61 to rotate. External shafts 610 are fixedly mounted on both sides of the tilting shell assembly 61, and the external shafts 610 are rotatably mounted in the positioning ring seat 421. The angle drive component 62 is fixedly mounted on the outer surface of the longitudinal shell 41. The tilting shell assembly 61 is connected to the positioning ring seat 421 of the first lifting frame 4 via the external shafts 610, and the precise angle rotation of the tilting shell assembly 61 is achieved via the angle drive component 62. This allows the equipment to adaptively adjust according to the bending angle of the pipe in the BIM model, enabling cutting and welding of pipes at any angle. The tilting shell assembly 61 includes an inlet shell 611 and a transmission shell 612. The inlet shell 611 is fixedly mounted on one end of the transmission shell 612, and guide grooves 613 are provided on both sides of the inlet shell 611 and the transmission shell 612. The internal structure of the tilting shell assembly 61 is further refined. The inlet shell 611 provides the pipe inlet, while the transmission shell 612 integrates the drive and control mechanisms. The guide grooves 613 on both sides provide a stable motion trajectory for the clamping and feeding assembly 7, ensuring its precise movement within the tilting housing 61. The angle drive component 62 includes a side motor 621 and a drive gear 622. The side motor 621 is fixedly mounted on the outer side of the longitudinal housing 41, and the drive gear 622 is sleeved and fixed on the output shaft of the side motor 621. A driven gear 623 meshing with the drive gear 622 is fixedly mounted on the outer end of the outer shaft 610. By designing the angle drive component 62 into a structure where the side motor 621 and the drive gear 622 cooperate, it is ensured that during use, the side motor 621 drives the driven gear 623 on the outer shaft 610 to rotate via the drive gear 622, thereby driving the tilting housing 61 to adjust the angle. The gear transmission method has a compact structure, high transmission accuracy, and rapid response, enabling precise angle control. A preferred model is the side motor 621, which can be a servo motor, such as the Panasonic MINAS A5 series, which has high precision and high responsiveness. The drive gear 622 and driven gear 623 can be high-precision hardened gears made of alloy steel, which are precision machined and heat-treated to ensure wear resistance and transmission accuracy.

[0045] Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10The clamping and feeding assembly 7 includes a clamping roller frame 71, an external slide 72, and a control component 73. Two sets of external slides 72 are symmetrically mounted on a tilting shell assembly 61. The external slides 72 are slidably mounted in a guide groove 613, with their lower ends extending through the guide groove 613 into the tilting shell assembly 61. The clamping roller frame 71 is fixedly mounted on the lower end of the external slides 72. The control component 73 is mounted on the tilting shell assembly 61 and is used to adjust the distance between the two sets of external slides 72. The composition and working principle of the clamping and feeding assembly 7 are described. By designing the clamping and feeding assembly 7 with a structure in which the clamping roller frame 71, the external slide 72, and the control component 73 cooperate, during use, the two symmetrical sets of external slides 72 move in the guide groove 613, driving the clamping roller frame 71 to clamp and feed the pipe. The control component 73 can precisely adjust the spacing between the two sets of external sliding frames 72, thereby achieving adaptive clamping of pipes of different diameters. This ensures the stability and feeding accuracy of the pipes during cutting or welding. The clamping roller frame 71 includes a wheel base 711, a drive clamping roller 712, and a feeding clamping roller 713. The drive clamping roller 712 is rotatably mounted on the head of the wheel base 711, and a bottom motor 714 that drives the drive clamping roller 712 is fixedly mounted on the lower end of the wheel base 711. The drive clamping roller 712 rotates evenly within the wheel base 711. This further refines the structure of the clamping roller frame 71. The cooperation between the drive clamping roller 712 and the feeding clamping roller 713 enables stable clamping of the pipes, and the rotation of the drive clamping roller 712 achieves precise feeding of the pipes. The bottom motor 714 directly drives the clamping roller 712, resulting in high transmission efficiency and precise control. The preferred configuration is as follows: the bottom motor 714 can be a DC brushless motor, such as the FAULHABER series, providing high torque and precise speed control; the drive clamping roller 712 and the feeding clamping roller 713 can be coated with wear-resistant rubber or polyurethane, providing good friction and protection for the pipe surface. A connecting solenoid 721 is fixedly installed in the middle of the external carriage 72. The control assembly 73 includes a top motor 731 and a double-ended screw 732 that cooperates with the connecting solenoid 721. The two ends of the double-ended screw 732 are rotatably mounted on the upper end of the transmission housing 612. The top motor 731 is fixedly mounted on the upper surface of the transmission housing 612 and is connected to the double-ended screw 732 via a transmission belt. The drive and adjustment mechanisms of the control assembly 73 are described in detail. The top motor 731 drives the double-ended screw 732 to rotate via a transmission belt. The double-ended screw 732, through the connecting solenoid 721, drives two sets of external sliding frames 72 to move inward or outward, thereby achieving adaptive clamping of the pipe diameter and precise control of the pipe spacing. This design achieves precise control of the clamping torque, ensuring the stability and reliability of the clamping.Preferred models include: Top motor 731, which can be a stepper motor or servo motor, such as the Kollmorgen AKM series, providing high-precision positioning and torque control; Double-ended screw 732, which can be a high-precision trapezoidal screw with an anti-loosening structure to ensure the stability and repeatability of adjustment; and Drive belt, which can be a synchronous belt, such as the Gates PowerGrip GT series, featuring constant transmission ratio and no slippage. The implementation principle of the BIM model-based digital pipe cutting and welding equipment in this application embodiment is as follows: During actual processing, firstly, the precise geometric information of the pipe to be processed is obtained through the BIM model, including its length, diameter, bending angle, and position. This information is input into the core controller of the equipment. The controller plans the digital cutting or welding path based on this data, generates an optimized cuttable range, and, combined with the movement range of the cutting machine, generates the position to be cut. One end of the pipe to be processed is inserted into the feed shell 611 of the flip shell assembly 61, and the other end is inserted into the auxiliary guide shell 8 (the auxiliary guide shell 8 can be omitted when the pipe is short). This ensures the stable fixation of the pipe in the equipment and allows the cutting component or welding robot to accurately align with the middle of the pipe for operation.

[0046] Then, angle and height adjustments are performed. The controller, based on BIM model data, drives the angle motor (not explicitly labeled), but to achieve rotation of the rotating seat, the control ring frame 3 rotates as a whole, aligning the flip shell assembly 61 with the cutting or welding area of ​​the pipe. Simultaneously, the side motor 621 in the angle drive component 62 drives the flip shell assembly 61 to precisely adjust its angle around the outer shaft 610 to match the pipe's bending angle. Electric cylinders 301 and 302, based on the pipe height information in the BIM model, adjust the heights of the first lifting frame 4 and the second lifting frame 5 respectively, ensuring the clamping and feeding assembly 7 and the auxiliary guide shell 8 are in the optimal working position, guaranteeing that the cutting or welding assembly can accurately contact the pipe surface. Once the pipe is positioned, the top motor 731 is activated, driving the double-headed screw 732 to rotate via a transmission belt. The double-headed screw 732 drives the connecting screw tube 721 inward, causing the two sets of external sliding frames 72 to move inward, simultaneously driving the clamping roller frame 71 to clamp the pipe. The clamping force can be precisely controlled by adjusting the torque or speed of the top motor, ensuring clamping stability and protecting the pipe surface.

[0047] Finally, cutting or welding operations are performed. When cutting is required, after the pipe is securely clamped, the cutting components, such as laser cutting heads or plasma cutting heads (not described in detail in the claims, but essential for the cutting function), begin operation and perform precise cutting according to a preset cutting path. When welding is required, after the pipe is securely clamped, the welding robot, such as a welding torch mounted on a robotic arm (not described in detail in the claims, but essential for the welding function), begins operation and performs precise welding according to a preset welding path. After cutting or welding is completed, the bottom motor 714 is activated, driving the drive clamping wheel 712 to rotate. The drive clamping wheel 712, through friction with the pipe, pushes the pipe axially to move a set length, preparing for the next cutting or welding operation. In this way, the equipment can achieve continuous automated processing operations without human intervention.

[0048] Repeat the above steps until all pipe cutting or welding tasks are completed. Once finished, release the pipes from the equipment, ready for the next batch of processing.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
