Description

Technical Field

[0001] This invention relates to the field of pipe cutting equipment technology, specifically to an anti-deviation pipe cutting device for water conservancy engineering construction. Background Technology

[0002] In water conservancy engineering construction, pipelines, as core components for water conveyance, drainage, and the connection of water conservancy facilities, directly affect the quality and safety of the project due to their cutting precision. Whether it's the steel pipe connection of water conveyance trunk lines, the laying of PE pipes for irrigation systems, or the installation of concrete pipes in dam seepage prevention projects, precise pipe cutting is essential to ensure interface fit, sealing performance, and structural stability. If the cut is off, it may lead to excessive gaps between pipe connections, uneven stress, and consequently, problems such as leakage, pressure loss, or even pipe rupture. In severe cases, this can affect the overall function of the water conservancy project and increase subsequent maintenance costs.

[0003] Traditional pipe cutting equipment causes the pipe to shake or shift due to the cutting impact during the cutting process. There is no structure to limit the pipe at the cut point, and the overall limiting structure has poor limiting effect, making it easy for the pipe to deviate during the cutting process. This results in low overall cutting accuracy and requires cutting to the required length. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pipe cutting device for preventing deviation during water conservancy engineering construction, comprising a conveying component and a cutting component, wherein the conveying component penetrates the cutting component;

[0005] A positioning component is fixedly installed at the output end of the conveying component.

[0006] The positioning component includes a vertical plate, which has an inner cavity, and a fastener is fixedly connected inside the inner cavity;

[0007] The fixing component includes hydraulic rods, which are fixedly installed inside the inner cavity. There are two hydraulic rods. The output end of the hydraulic rod is fixedly connected to an arc-shaped plate, and the end of the arc-shaped plate is fixedly connected to a fixing block. A rotating rod is rotatably connected to the side of the fixing block near the arc-shaped plate. One end of the pipe is installed inside the push plate, and the other end of the pipe is located inside the inner cavity. The pipe is positioned between the two intermediate rods and the two rotating rods on both sides. Subsequently, the hydraulic rods work to push the arc-shaped plate towards the central pipe, causing the arc-shaped plate to push the rotating rod to contact the outer side of the pipe in the horizontal direction. At the same time, as the arc-shaped plate moves, the arc-shaped block slides inside the arc-shaped groove, thereby compressing the spring and making the intermediate rod perpendicular to the pipe. The outer contact in the direction, the grid structure, with the middle rod and rotating rod forming a surrounding limit on the pipe from four directions (up, down, left, and right), can firmly fix the pipe in the middle position, effectively avoiding the pipe's position deviation caused by external forces such as the impact of the cutting tool or the pipe's own vibration during the cutting process, ensuring the accuracy of the cutting trajectory, and can adapt to pipes of different diameters within a certain range. By adjusting the distance between the middle rod and the rotating rod, the pipe is always kept stable in the middle, enhancing the versatility and flexibility of positioning. An arc-shaped groove is opened on one side of the arc plate, and an arc-shaped block is slidably connected inside the arc-shaped groove. The end of the arc block away from the arc-shaped groove is fixedly connected to the middle rod. There are two middle rods, and the middle rod and the rotating rod form a grid structure.

[0008] An electric push rod is fixedly connected to the side of the positioning component near the cutting component. A guide rod is fixedly connected to the output end of the electric push rod. The guide rod is slidably connected to the positioning component. A baffle is fixedly connected to the end of the guide rod away from the electric push rod. A collection frame is fixedly connected to the end of the positioning component away from the conveying component. A conical cylinder is fixedly connected to the middle of the side of the baffle near the guide rod.

[0009] The upright plate is fixedly connected to the end of the conveying assembly near the cutting assembly. A guide plate is fixedly connected to the side of the upright plate away from the cutting assembly. An electric actuator is fixedly connected to the side of the upright plate near the cutting assembly, and the output end of the electric actuator passes through the upright plate. The guide rod is slidably connected to the guide plate. A side plate is fixedly connected to the bottom of the side of the upright plate near the collection frame. There are two side plates, which are symmetrically arranged with the collection frame as the center. An inclined plate is fixedly connected to the side of the upright plate near the guide plate. The symmetrically arranged inclined plates slope from the outlet end of the pipe towards the middle, forming a natural guide channel. When the material in the pipe is discharged, the inclined plate can receive the material and guide it to slide down along the inclined direction into the inside of the collection frame, avoiding the accumulation or retention of material at the outlet end. This design reduces the manual cleaning of accumulated material and makes the material conveying process smoother. At the same time, the inclined plate buffers the impact force and reduces the probability of material deformation or damage due to collision. There are two inclined plates, which are symmetrically arranged on the upright plate. The inclined plate is located below the guide plate, and the side plate is located below the inclined plate.

[0010] Two hydraulic rods are symmetrically arranged inside the inner cavity. There are two arc-shaped plates, and two fixing blocks are symmetrically arranged at both ends of the arc-shaped plates. There are two arc-shaped blocks, and the two arc-shaped blocks are symmetrically arranged with the middle rod as the center. Compression springs are fixedly connected to the opposite sides of the two arc-shaped blocks. The grid structure forms an encircling fixation from the top, bottom, left, and right directions of the pipe. The contact points with the pipe are evenly distributed, which can distribute the fixing force to multiple positions on the pipe surface and avoid excessive local stress that may cause pipe deformation or surface damage. The two middle rods are symmetrically arranged with the compression spring as the center. The two ends of the compression spring are fixedly connected to the two arc-shaped blocks located in the same arc-shaped groove. There are two rotating rods, and the two rotating rods are symmetrically arranged on an arc-shaped plate with the middle rod as the center.

[0011] In the second embodiment, based on the first embodiment, as shown in the figure, the conveying assembly includes a platform that passes through the cutting assembly. The end of the platform near the cutting assembly is fixedly connected to a vertical plate. The platform has a U-shaped design, and two slide rails are fixedly connected to the open end of the platform. A push plate is slidably connected to the top of each slide rail. The push plate is located at the end of the platform away from the cutting assembly. A through hole is provided in the middle of the push plate, and a clamping block is slidably connected inside the through hole. One end of the pipe is placed in the middle of the push plate, and then the clamping block slides inside the push plate, making axial contact with the end of the pipe, thereby clamping the end of the pipe. Then, the push plate slides on the top of the slide rails, causing the push plate to push the pipe along the guide wheel towards the cutting assembly. The electric actuator moves the guide rod and baffle to adjust the cutting length of the pipe. By fixing the end, it can effectively limit the displacement and shaking during operation, ensuring accurate welding point connection and reducing problems such as weld deviation and incomplete welding. There are multiple clamping blocks, which are evenly distributed inside the through hole of the push plate. There are multiple connecting seats that slide inside the opening of the platform. Two connecting seats are grouped together. Guide wheels are set on the opposite sides of the two connecting seats in a group. The two ends of the guide wheels are rotatably connected to the two connecting seats in the group. A base is fixedly connected to the end of the platform away from the push plate. There are two V-shaped blocks fixedly connected to the top of the base. A slot is opened in the middle of the top of the V-shaped block.

[0012] In the third embodiment, based on embodiments one and two, as shown in Figures 1-2, the cutting assembly includes a gantry frame. A platform passes through the gantry frame, and two square slots are formed on the inner side of the gantry frame. A screw is rotatably connected inside each square slot. A motor is fixedly connected to the top of the gantry frame, and the output end of the motor is fixedly connected to the screw. A slider is provided inside each square slot, with its two ends located inside the two square slots respectively. The slider is rotatably connected to the screw, and a connecting plate is fixedly connected to one side of the slider. When the push plate pushes the end of the pipe away from the push plate to contact the baffle, the motor, powered by an external power source, operates. The motor drives the screw to rotate, causing the screw to move the slider downwards, allowing the slider to pass through... The connecting plate moves the positioning plate downwards, positioning it inside the slot of the V-block. At this point, the positioning plate and the groove of the V-block naturally fit the outer contour of the pipe, forming a wrap-around clamping effect on the pipe from both sides of the cutting edge. As the slider continues to move downwards, the externally powered motor operates, driving the rotating shaft to rotate. This rotating shaft then drives the cutting blade to rotate, thus cutting the pipe. This close fit allows the fixing force to be applied more evenly to the pipe surface, avoiding pipe deformation caused by excessive localized force. It also effectively limits the radial rotation and axial movement of the pipe during the cutting process, ensuring the stability of the cutting position and providing a foundation for precise cutting. Furthermore, the fixing points are concentrated... The design minimizes interference with other parts of the pipeline at both sides of the cutting area. It also avoids uneven stress on the pipeline caused by overall fixation, reducing the risk of secondary deformation due to fixation. Simultaneously, the stable fixation near the cutting area allows the cutting tool to be closer to the work point, reducing cutting deviations caused by pipeline movement and improving the flatness and perpendicularity of the cut surface. The connecting plate has a V-shaped design, with both ends fixedly connected to the slider. A motor is fixedly connected to one connecting plate near the positioning component, located in the middle of the connecting plate away from the slider. A rotating shaft is located on the opposite side of the connecting plate, with both ends rotatably connected to the two connecting plates. The motor's output end passes through... A connecting plate is fixedly connected to a rotating shaft. A cutting blade is fixedly connected to the middle of the outer side of the rotating shaft. A protective cover is fitted on the outer side of the cutting blade. The side of the protective cover near the motor is rotatably connected to the rotating shaft. An annular groove is opened inside the connecting plate. A cleaning component is installed inside the protective cover near the cutting blade. A sliding rod is slidably connected inside the annular groove. A return spring is fixedly connected to the outer side of the sliding rod. The end of the return spring away from the sliding rod is fixedly connected to the bottom of the slider. Two connecting rods are slidably connected inside the connecting plate. A positioning plate is fixedly connected to the bottom of the connecting rod. The positioning plate has a V-shaped design. A limit plate is fixedly connected to the end of the connecting rod away from the positioning plate. The limit plate is located inside the connecting plate.

[0013] The cleaning component includes a rotating plate. A limit rod is fixedly connected to the side of the rotating plate near the protective cover, penetrating the protective cover. A circular block is fixedly connected to the end of the limit rod away from the rotating plate. A through groove is formed in the middle of the outer side of the circular block, and a cleaning plate is fixedly connected inside the through groove. The end of the cleaning plate near the cutting blade is trapezoidal, and the opposite end of the arc plate is inclined. The inclined sides of the arc plate and the cleaning plate are parallel. The cleaning plate is installed inside the groove of the circular block, and then a fixing plate is installed inside the groove. At the same time, the end of the arc plate contacts the side of the cleaning plate, thus mounting the cleaning plate on the circular block. The machine's operation drives the rotating shaft to rotate, which in turn drives the cutting blade to rotate, thus cutting the pipe. At the same time, the cleaning plate cleans the edge surface of the cutting blade, promptly removing impurities and extending its service life. A groove is opened in the middle of the side of the cleaning plate away from the circular block. An arc plate is fixedly connected to the outer side of the circular block near the cleaning plate. There are two arc plates, and a fixing plate is fixedly connected to the opposite side of the arc plates. The fixing plate is located inside the groove. A pressure spring is set on the outer side of the limiting rod, and a turntable is rotatably connected to the outer side of the limiting rod. The two ends of the pressure spring are fixedly connected to the turntable and the circular block, respectively.

[0014] This invention provides a pipe cutting device for preventing pipe deviation during hydraulic engineering construction. It has the following beneficial effects:

[0015] I. The anti-deviation pipe cutting equipment used in this water conservancy project employs a grid structure with a central rod and rotating rod forming a closed-loop limit on the pipe from four directions (up, down, left, and right). This firmly fixes the pipe in the center position, effectively preventing pipe deviation caused by external forces such as the impact of the cutting tool or the pipe's own vibration during the cutting process. This ensures the accuracy of the cutting trajectory and can adapt to pipes of different diameters within a certain range. By adjusting the distance between the central rod and rotating rod, the pipe is always kept stable in the center, enhancing the versatility and flexibility of the positioning.

[0016] Second, the anti-deviation pipe cutting equipment used in this water conservancy project adjusts the cutting length of the pipe by moving the guide rod and baffle through the operation of the electric actuator. After fixing the end, it can effectively limit the displacement and shaking during the operation, ensure precise connection of the welding points, and reduce problems such as weld deviation and incomplete welding.

[0017] Third, the anti-deviation pipe cutting equipment used in this water conservancy project uses symmetrically arranged inclined plates that tilt from the pipe outlet end towards the middle to form a natural guide channel. When the material in the pipe is discharged, the inclined plates can receive the material and guide it to slide down along the inclined direction and fall into the inside of the collection box, avoiding the accumulation or retention of material at the outlet end. This design reduces the need for manual cleaning of accumulated material and makes the material conveying process smoother.

[0018] Fourth, the anti-deviation pipe cutting equipment used in this water conservancy project, by concentrating the fixed points on both sides of the cutting point, can minimize interference with other parts of the pipe, avoid uneven stress on the pipe caused by overall fixing, reduce the risk of secondary deformation caused by fixing, and at the same time, the stable fixing near the cutting area allows the cutting tool to be closer to the work point, reduce cutting deviation caused by pipe shaking, and improve the flatness and verticality of the cutting surface.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] First embodiment, such as Figures 1 to 6 As shown, the present invention provides a technical solution: a pipe cutting device for preventing deviation in water conservancy engineering construction, comprising a conveying component 1 and a cutting component 2, wherein the conveying component 1 passes through the cutting component 2;

[0036] Positioning component 3 is fixedly installed at the output end of conveying component 1;

[0037] The positioning component 3 includes a vertical plate 31, and an inner cavity 35 is opened inside the vertical plate 31. A fastener 36 is fixedly connected inside the inner cavity 35.

[0038] The fixing component 36 includes a hydraulic rod 361, which is fixedly installed inside the inner cavity 35. There are two hydraulic rods 361. The output end of the hydraulic rod 361 is fixedly connected to an arc-shaped plate 362. The end of the arc-shaped plate 362 is fixedly connected to a fixing block 364. A rotating rod 365 is rotatably connected to the side of the fixing block 364 near the arc-shaped plate 362. One end of the pipe is installed inside the push plate 15, and the other end of the pipe is located inside the inner cavity 35. The pipe is located between the two intermediate rods 366 and the two rotating rods 365 on both sides. Then, the hydraulic rod 361 works to push the arc-shaped plate 362 to move towards the middle of the pipe, so that the arc-shaped plate 362 pushes the rotating rod 365 to contact the outer side of the pipe in the horizontal direction. At the same time, as the arc-shaped plate 362 moves, the arc-shaped block 367 slides inside the arc-shaped groove 363, thereby compressing the spring 368. This allows the intermediate rod 366 to contact the outer side of the pipe in the vertical direction. The grid structure, formed by the intermediate rod 366 and the rotating rod 365, encloses and limits the pipe from four directions (up, down, left, and right), firmly fixing the pipe in the middle position. This effectively prevents the pipe from shifting due to external forces such as the impact of the cutting tool or the vibration of the pipe itself during the cutting process, ensuring the accuracy of the cutting trajectory. It can adapt to pipes of different diameters within a certain range. By adjusting the distance between the intermediate rod 366 and the rotating rod 365, the pipe is always kept stable in the middle, enhancing the versatility and flexibility of the positioning. An arc groove 363 is opened on one side of the arc plate 362. An arc block 367 is slidably connected inside the arc groove 363. The end of the arc block 367 away from the arc groove 363 is fixedly connected to the intermediate rod 366. There are two intermediate rods 366. The intermediate rods 366 and the rotating rod 365 form a grid structure.

[0039] An electric push rod 5 is fixedly connected to the side of the positioning component 3 near the cutting component 2. A guide rod 6 is fixedly connected to the output end of the electric push rod 5. The guide rod 6 is slidably connected to the positioning component 3. A baffle 7 is fixedly connected to the end of the guide rod 6 away from the electric push rod 5. A collection frame 4 is fixedly connected to the end of the positioning component 3 away from the conveying component 1. A conical cylinder 8 is fixedly connected to the middle of the side of the baffle 7 near the guide rod 6.

[0040] The upright plate 31 is fixedly connected to the end of the conveying assembly 1 near the cutting assembly 2. A guide plate 34 is fixedly connected to the side of the upright plate 31 away from the cutting assembly 2. An electric push rod 5 is fixedly connected to the side of the upright plate 31 near the cutting assembly 2. The output end of the electric push rod 5 passes through the upright plate 31. A guide rod 6 is slidably connected to the guide plate 34. A side plate 32 is fixedly connected to the bottom of the side of the upright plate 31 near the collecting frame 4. There are two side plates 32, which are symmetrically arranged with the collecting frame 4 as the center. An inclined plate 33 is fixedly connected to the side of the upright plate 31 near the guide plate 34. The symmetrically arranged inclined plates 33 are located at the discharge end of the pipe. Inclined towards the center, forming a natural guiding channel, when material is discharged from the pipe, the inclined plate 33 can receive the material and guide it to slide down along the inclined direction and fall into the collection frame 4, avoiding material accumulation or retention at the discharge end. This design reduces the manual cleaning of accumulated material, making the material conveying process smoother. At the same time, the inclined plate 33 buffers the impact force through its receiving action, reducing the probability of material deformation or damage due to collision. There are two inclined plates 33, which are symmetrically arranged on the vertical plate 31. The inclined plate 33 is located below the guide plate 34, and the side plate 32 is located below the inclined plate 33.

[0041] Two hydraulic rods 361 are symmetrically arranged inside the inner cavity 35. There are two arc-shaped plates 362, which are symmetrically arranged inside the inner cavity 35. There are two fixing blocks 364, which are symmetrically arranged at both ends of the arc-shaped plates 362. There are two arc-shaped blocks 367, which are symmetrically arranged with the middle rod 366 as the center. Compression springs 368 are fixedly connected to the opposite sides of the two arc-shaped blocks 367. The grid structure forms a surrounding fixation from the top, bottom, left, and right directions of the pipe. The contact points with the pipe are evenly distributed, which can distribute the fixing force to multiple positions on the pipe surface and avoid excessive local force that may cause pipe deformation or surface damage. The two middle rods 366 are symmetrically arranged with the compression springs 368 as the center. The two ends of the compression springs 368 are fixedly connected to the two arc-shaped blocks 367 located in the same arc-shaped groove 363. There are two rotating rods 365, which are symmetrically arranged on an arc-shaped plate 362 with the middle rod 366 as the center.

[0042] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 7As shown, the conveying assembly 1 includes a platform 11 that passes through the cutting assembly 2. One end of the platform 11 near the cutting assembly 2 is fixedly connected to a vertical plate 31. The platform 11 has a U-shaped design. A slide rail 12 is fixedly connected to the open end of the platform 11. There are two slide rails 12. A push plate 15 is slidably connected to the top of the slide rail 12. The push plate 15 is located at the end of the platform 11 away from the cutting assembly 2. A through hole is provided in the middle of the push plate 15. A clamping block 16 is slidably connected inside the through hole of the push plate 15. One end of the pipe is placed in the middle of the push plate 15, and then the clamping block 16 slides inside the push plate 15, making axial contact with the end of the pipe, thereby clamping the end of the pipe. Then, the push plate 15 slides on the top of the slide rail 12, causing the push plate 15 to push the pipe on the guide wheel 14 towards the cutting assembly 2. The push rod 5 pushes the guide rod 6 and the baffle 7 to move, thereby adjusting the cutting length of the pipe. After fixing the end, it can effectively limit the displacement and shaking during operation, ensure accurate welding point connection, and reduce problems such as welding deviation and incomplete welding. There are multiple clamping blocks 16, which are evenly distributed inside the through hole of the push plate 15. The opening of the platform 11 is slidably connected to the connecting seat 13. There are multiple connecting seats 13, and two connecting seats 13 are divided into a group. The two connecting seats 13 in a group are provided with guide wheels 14 on opposite sides. The two ends of the guide wheels 14 are rotatably connected to the two connecting seats 13 in the group. The end of the platform 11 away from the push plate 15 is fixedly connected to the base 17. The top of the base 17 is fixedly connected to the V-shaped block 18. There are two V-shaped blocks 18. A slot 19 is opened in the middle of the top of the V-shaped block 18.

[0043] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 14As shown, the cutting assembly 2 includes a gantry frame 21, through which a platform 11 passes. Two square slots 22 are formed on the inner side of the gantry frame 21. A screw 23 is rotatably connected inside each square slot 22. A motor 24 is fixedly connected to the top of the gantry frame 21, and its output end is fixedly connected to the screw 23. A slider 25 is installed inside each square slot 22, with its two ends located inside the two square slots 22 respectively. The slider 25 is rotatably connected to the screw 23. A connecting plate 26 is fixedly connected to one side of the slider 25. When the push plate 15 pushes the end of the pipe furthest from the push plate 15 into contact with the baffle 7, the motor 24, powered by an external power source, operates. The motor 24 drives the screw 23 to rotate, causing the screw 23 to move the slider 25 downwards. This causes the slider 25 to move downwards via the connecting plate 26, moving the positioning plate 213 downwards. The positioning plate 213 then positions itself inside the slot 19 of the V-block 18. At this point, the positioning plate 213 and the groove of the V-block 18 naturally fit the outer contour of the pipe, forming a wrap-around clamping effect on the pipe from both sides of the cutting point. As the slider 25 continues to move downwards, the motor 27, powered by an external power source, operates, driving the rotating shaft 211 to rotate. This, in turn, drives the cutting blade 212 to rotate, thus cutting the pipe. This close fit allows the fixing force to be applied more evenly to the pipe surface, preventing pipe deformation caused by excessive localized force. Simultaneously, it effectively limits the radial rotation and axial movement of the pipe during the cutting process, ensuring the stability of the cutting position and providing precision. The precise cutting provides a foundation, and the fixed points are concentrated on both sides of the cutting area, which minimizes interference with other parts of the pipeline. It also avoids uneven stress on the pipeline caused by overall fixing, reducing the risk of secondary deformation caused by fixing. At the same time, the stable fixing near the cutting area allows the cutting tool to be closer to the work point, reducing cutting deviation caused by pipeline shaking and improving the flatness and perpendicularity of the cut surface. The connecting plate 26 has a V-shaped design, and both ends of the connecting plate 26 are fixedly connected to the slider 25. A motor 27 is fixedly connected to one of the connecting plates 26 near the positioning component 3. The motor 27 is located in the middle of the connecting plate 26 away from the slider 25. A rotating shaft 211 is provided on the opposite side of the connecting plate 26, and the two ends of the rotating shaft 211 are respectively connected to two connecting... The connecting plate 26 is rotatably connected. The output end of the motor 27 passes through the connecting plate 26 and is fixedly connected to the rotating shaft 211. A cutting blade 212 is fixedly connected to the middle of the outer side of the rotating shaft 211. A protective cover 210 is fitted on the outer side of the cutting blade 212. The side of the protective cover 210 near the motor 27 is rotatably connected to the rotating shaft 211. An annular groove 217 is formed inside the connecting plate 26. A cleaning component 28 is provided inside the protective cover 210 near the cutting blade 212. A sliding rod 29 is slidably connected inside the annular groove 217. A return spring 216 is fixedly connected to the outer side of the sliding rod 29. The end of the return spring 216 away from the sliding rod 29 is fixedly connected to the bottom of the slider 25. Two connecting rods 214 are slidably connected inside the connecting plate 26.A positioning plate 213 is fixedly connected to the bottom of the connecting rod 214. The positioning plate 213 has a V-shaped design. A limiting plate 215 is fixedly connected to the end of the connecting rod 214 away from the positioning plate 213. The limiting plate 215 is located inside the connecting plate 26.

[0044] The cleaning component 28 includes a rotating plate 281. A limiting rod 282 is fixedly connected to the side of the rotating plate 281 near the protective cover 210. The limiting rod 282 passes through the protective cover 210, and a circular block 283 is fixedly connected to the end of the limiting rod 282 away from the rotating plate 281. A through groove 285 is opened in the middle of the outer side of the circular block 283. A cleaning plate 284 is fixedly connected inside the through groove 285. The end of the cleaning plate 284 near the cutting blade 212 is trapezoidal, and the opposite end of the arc plate 286 is inclined. The arc plate 286 and the inclined side of the cleaning plate 284 are parallel. The cleaning plate 284 is installed inside the groove 2810 of the circular block 283. Then, a fixing plate 289 is installed inside the groove 2810. At the same time, the end of the arc plate 286 contacts the side of the cleaning plate 284, so that the cleaning plate 284 is installed on the circular block 283. The motive 27 drives the rotating shaft 211 to rotate, which in turn drives the cutting blade 212 to rotate, thereby cutting the pipe. At the same time, the cleaning plate 284 cleans the edge surface of the cutting blade 212, removing impurities and extending its service life. The cleaning plate 284 has a slot 2810 in the middle of the side away from the round block 283. An arc plate 286 is fixedly connected to the outer side of the round block 283 near the cleaning plate 284. There are two arc plates 286. A fixing plate 289 is fixedly connected to the opposite side of the arc plates 286. The fixing plate 289 is located inside the slot 2810. A pressure spring 288 is provided on the outer side of the limiting rod 282. A turntable 287 is rotatably connected to the outer side of the limiting rod 282. The two ends of the pressure spring 288 are fixedly connected to the turntable 287 and the round block 283, respectively.

[0045] In use, one end of the pipe is placed in the middle of the push plate 15, and then the clamping block 16 slides inside the push plate 15, so that the clamping block 16 contacts the axial outer side of the end of the pipe, thereby clamping the end of the pipe. Then the push plate 15 slides on the top of the slide rail 12, so that the push plate 15 pushes the pipe to move towards the cutting assembly 2 on the guide wheel 14.

[0046] The other end of the pipe is positioned inside the inner cavity 35, with the pipe located between the two intermediate rods 366 and the two rotating rods 365 on both sides. Subsequently, the hydraulic rod 361 works to push the arc plate 362 towards the middle of the pipe, causing the arc plate 362 to push the rotating rod 365 to contact the outer side of the pipe in the horizontal direction. At the same time, as the arc plate 362 moves, the arc block 367 slides inside the arc groove 363, thereby compressing the spring 368 and causing the intermediate rod 366 to contact the outer side of the pipe in the vertical direction. The grid structure, formed by the intermediate rods 366 and the rotating rods 365, encloses and limits the pipe from four directions: up, down, left, and right. The electric actuator 5 works to push the guide rod 6 and the baffle 7 to move, thereby adjusting the cutting length of the pipe.

[0047] When the pusher plate 15 pushes the end of the pipe away from the pusher plate 15 into contact with the baffle 7, the motor 24 is powered by an external power source. The motor 24 drives the screw 23 to rotate, causing the screw 23 to move the slider 25 downward. The slider 25 then drives the positioning plate 213 downward through the connecting plate 26, so that the positioning plate 213 is located inside the slot 19 of the V-block 18. At this time, the positioning plate 213 and the groove of the V-block 18 naturally fit with the outer contour of the pipe, forming a wrapping clamp on the pipe from both sides of the cutting point. As the slider 25 continues to move downward, the motor 27 is powered by an external power source. The motor 27 drives the rotating shaft 211 to rotate, causing the rotating shaft 211 to drive the cutting blade 212 to rotate, thereby cutting the pipe with the cutting blade 212.
