Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and more specifically to a cutting and forming equipment for high ring stiffness impact-resistant pipes. Background Technology

[0002] High ring stiffness impact-resistant pipes are widely used in municipal drainage, buried communication sheathing, and industrial fluid transportation due to their excellent ring stiffness, impact resistance, and corrosion resistance. These pipes typically have large wall thicknesses and multi-layered composite structures, which places higher demands on the cutting and forming processes.

[0003] Currently, conventional pipe cutting equipment mostly uses saw blades or single-edged blades for circumferential cutting. During the cutting process, there is a lack of effective synchronous support for the inner and outer walls of the pipe. Because high-ring-stiffness pipes still exhibit some elastic deformation, radial cutting forces can easily lead to pipe end out-of-roundness and excessive ellipticity, affecting the sealing performance of subsequent socket or heat-fusion connections between pipes. Furthermore, ordinary clamping mechanisms only clamp the pipe from the outside, easily causing localized indentations on the pipe wall or delamination between the reinforcing layer and the substrate. This is especially problematic for large-diameter, thick-walled pipes, where the external clamping force is difficult to distribute evenly, often resulting in burrs, cracks, or chipping at the cut end. In addition, the lack of automated internal and external clamping linkage and sequential control means that operation relies on manual experience, making it difficult to achieve consistent quality in mass production. Therefore, there is an urgent need for specialized equipment that can simultaneously support from the inside and clamp from the outside during the cutting process, achieving integrated cutting and forming operations to solve the prominent problems of deformation and low efficiency in the processing of high-ring-stiffness, impact-resistant pipes. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cutting and forming equipment for high ring stiffness impact-resistant pipes to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: a cutting and forming equipment for high ring stiffness impact-resistant pipe, including a mounting frame, a conveying roller mounted on the mounting frame, a motion mechanism provided on the top of the mounting frame, and a support mechanism provided on one side of the mounting frame. The motion mechanism is used to cut the high ring stiffness impact-resistant pipe and to keep the outer side of the pipe clamped and fixed during the cutting process. The support mechanism is used to keep the inner side of the pipe supported and fixed during the cutting process.

[0006] Preferably, the motion mechanism includes a cutting component and a positioning component. The cutting component includes a receiving frame, on which a blade is rotatably mounted. A connector is fixedly mounted on the top of the receiving frame for fixed connection with the output end of a hydraulic device. A power device is provided on the receiving frame for providing rotational force to the blade. A roller is also rotatably mounted on the receiving frame.

[0007] Preferably, the positioning component includes an annular cylinder and a movable frame. The annular cylinder is fixedly installed on the mounting frame. An internal groove is provided on the annular cylinder, and a traction component is provided in the internal groove. Three traction components are evenly arranged.

[0008] Preferably, the traction component includes a clamp, a sliding rod, and a guide post. The sliding rod is fixedly installed in the built-in groove, the clamp is sleeved on the surface of the sliding rod, and the guide post is fixedly installed on the clamp.

[0009] Preferably, a rotating plate is rotatably installed at the opening of the built-in groove, and a guide groove is opened on the rotating plate. Multiple guide grooves are evenly arranged, and the guide grooves are matched with the guide posts.

[0010] Preferably, a first fixed frame and a second fixed frame are fixedly connected to the outer surface of the annular cylinder. The first fixed frame and the second fixed frame are fixedly connected by a guide rod. The movable frame is sleeved on the surface of the guide rod, and a compression spring is also sleeved on the surface of the guide rod.

[0011] Preferably, the movable frame has inclined grooves and straight grooves, and the rollers can roll along the inclined grooves and straight grooves.

[0012] Preferably, a rack is fixedly connected to the bottom of the movable frame, a gear is rotatably mounted on the top of the annular cylinder, a gear ring is fixedly connected to the rotating plate, the rack is meshed with the gear, and the gear ring is meshed with the gear.

[0013] Preferably, the support mechanism includes an electric slide rail and a sliding plate. The electric slide rail is used to pull the sliding plate to move horizontally in a straight line. A stabilizing frame is fixedly connected to the top of the sliding plate. A cylinder is fixedly installed on the top of the stabilizing frame. A sleeve is also fixedly installed on the stabilizing frame.

[0014] Preferably, a connecting rod is fixedly connected to the cylinder output end. One end of the connecting rod passes through the sleeve. A telescopic assembly is provided on the outside of the sleeve. Multiple telescopic assemblies are evenly arranged. The telescopic assembly includes a support plate, a connecting rod one, a connecting rod two, and a connecting rod three. One end of connecting rod one is hinged to the support plate, and the other end is hinged to the outside of the sleeve. One end of connecting rod two is hinged to the support plate, and the other end is hinged to the outside of the sleeve. One end of connecting rod three is hinged to the support plate, and the other end is hinged to one end of the connecting rod.

[0015] The beneficial effects of this invention are: In this invention, the positioning component and the support mechanism work together in the motion mechanism to simultaneously fix and support the inner and outer walls of the pipe, improving the stability of the cutting process and the quality of the cut. Specifically, when the cutting component moves downwards, the rollers first roll along the inclined groove on the movable frame, driving the movable frame to move horizontally, which in turn drives the rotating plate to rotate. The guide groove on the rotating plate forces the three clamps to move radially and synchronously towards the center, uniformly clamping the pipe from the outside. Subsequently, the rollers enter the straight groove, maintaining a constant clamping force. Simultaneously, the electric slide rail in the support mechanism sends the telescopic component into the inner cavity of the pipe, and the cylinder drives the connecting rod assembly to cause multiple support plates to expand radially outwards synchronously, pressing against the pipe wall from the inside. This structural design of synchronous internal and external support effectively counteracts the radial cutting force generated during cutting, completely avoiding pipe end out-of-roundness or collapse, and is particularly suitable for large-diameter, thick-walled, high-ring-stiffness pipes. Furthermore, the equipment automatically feeds the pipe using conveyor rollers, and after cutting, the support mechanism can move the cut pipe section out, facilitating unloading. This forms a complete automated cycle of feeding, clamping, internal support, cutting, and removal, significantly improving processing efficiency. Compared with existing step-by-step processing equipment, this invention integrates external clamping, internal support and cutting into one unit, with high end face flatness and no delamination burrs. It has good versatility and practical value, and provides a reliable mechanical solution for the precision and efficient processing of high ring stiffness impact-resistant pipes.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 This invention provides a cutting and forming equipment for high ring stiffness impact-resistant pipes, including a mounting frame 1, a conveying roller 2 mounted on the mounting frame 1, a motion mechanism 3 provided on the top of the mounting frame 1, and a support mechanism 4 provided on one side of the mounting frame 1. The motion mechanism 3 is used to cut the high ring stiffness impact-resistant pipe and to keep the outer side of the pipe clamped and fixed during the cutting process. The support mechanism 4 is used to keep the inner side of the pipe supported and fixed during the cutting process.

[0028] Reference Figures 1 to 6 The motion mechanism 3 includes a cutting component 31 and a positioning component 32.

[0029] The cutting assembly 31 includes a receiving frame 311, on which a blade 312 is rotatably mounted. A connector 313 is fixedly mounted on the top of the receiving frame 311 for fixed connection with the output end of a hydraulic device. A power device 314 is provided on the receiving frame 311 to provide rotational force for the blade 312. A roller 315 is also rotatably mounted on the receiving frame 311. The cutting assembly 31 is linked with the hydraulic device through the connector 313 to realize the feeding and cutting of the blade 312. At the same time, the design of the roller 315 provides power input for subsequent clamping linkage, simplifying the drive structure.

[0030] The positioning assembly 32 includes an annular cylinder 321 and a movable frame 322. The annular cylinder 321 is fixedly mounted on the mounting frame 1. An internal groove 3211 is formed on the annular cylinder 3211, and a traction member 327 is disposed within the internal groove 3211. Three traction members 327 are evenly distributed. The positioning assembly 32 uses the annular cylinder 321 as the base and has three evenly distributed traction members 327 inside, providing a structural basis for the uniform clamping of the outer wall of the pipe and avoiding uneven local stress.

[0031] The traction component 327 includes a clamp 3271, a sliding rod 3272, and a guide post 3273. The sliding rod 3272 is fixedly installed in the built-in groove 3211, the clamp 3271 is sleeved on the surface of the sliding rod 3272, and the guide post 3273 is fixedly installed on the clamp 3271. A rotating plate 325 is rotatably installed at the opening of the built-in groove 3211. The rotating plate 325 has guide grooves 3251 evenly distributed, and the guide grooves 3251 match the guide posts 3273. Through the cooperation of the guide grooves 3251 and the guide posts 3273, the rotation of the rotating plate 325 can be converted into the radial sliding of the clamp 3271, achieving synchronous centripetal clamping. The structure is compact and the clamping action is precise.

[0032] A fixed frame 3212 and a fixed frame 3213 are fixedly connected to the outer surface of the annular cylinder 321. The fixed frame 3212 and the fixed frame 3213 are fixedly connected by a guide rod 323. A movable frame 322 is sleeved on the surface of the guide rod 323, forming a sliding guide fit with the guide rod 323 along its axial direction. A compression spring 3231 is also sleeved on the surface of the guide rod 323. The movable frame 322 has an inclined groove 3221 and a straight groove 3222, allowing the roller 315 to roll along these grooves. The sequential design of the inclined groove 3221 and the straight groove 3222 ensures that the roller 315 first drives the movable frame 322 to translate and clamp. After entering the straight groove 3222, the clamping force remains constant, while the compression spring 3231 provides power for resetting, thus achieving automatic sequential control of clamping and releasing.

[0033] A rack 328 is fixedly connected to the bottom of the movable frame 322, a gear 324 is rotatably mounted on the top of the annular cylinder 321, and a gear ring 326 is fixedly connected to the rotating plate 325. The rack 328 and gear 324 are meshed together. Through the two-stage transmission of the rack 328, gear 324, and gear ring 326, the horizontal movement of the movable frame 322 is efficiently converted into the rotational movement of the rotating plate 325, ensuring the strict synchronization of the three chucks 3271.

[0034] In use, the conveying roller 2 transports the high-ring stiffness, impact-resistant pipe and pulls it through the annular cylinder 321. When the pipe reaches the preset position, the conveying roller 2 stops transporting, and the hydraulic equipment drives the cutting assembly 31 to move downwards as a whole through the connector 313. During this process, the roller 315 of the cutting assembly 31 first rolls downwards along the inclined groove 3221. As the roller 315 rolls along the inclined groove 3221, due to the compression of the roller 315, the movable frame 322 slides along the guide rod 323, compressing the spring 32. 31 gradually stretches and increases elasticity, the movable frame 322 moves and drives the gear 324 to rotate around its own axis through the rack 328, the gear 324 rotates and drives the rotating plate 325 to rotate around its own axis through the gear ring 326, during the rotation of the rotating plate 325, with the cooperation of the guide groove 3251 and the guide post 3273, the chuck 3271 slides along the sliding rod 3272, and the three chucks 3271 move synchronously towards the center of the annular cylinder 321, the chucks 3271 clamp and fix the pipe; Afterwards, the roller 315 leaves the inclined groove 3221 and rolls down along the straight groove 3222. During this process, the position of the chuck 3271 remains unchanged, and the chuck 3271 keeps the pipe clamped and fixed. At the same time, the support mechanism 4 supports and fixes the inner side of the pipe. Afterwards, the cutting assembly 31 continues to move downwards as a whole, the roller 315 continues to roll downwards along the straight groove 3222, and the blade 312, which rotates under the drive of the power device 314, passes through the pipe and cuts the pipe. Afterwards, the support mechanism 4 releases its support and fixation on the inside of the cut pipe, and the workers can then remove the cut pipe. Subsequently, the hydraulic equipment drives the cutting assembly 31 to move upward as a whole. During this process, the roller 315 of the cutting assembly 31 first rolls upward along the straight groove 3222. During this process, the position of the chuck 3271 remains unchanged. When the roller 315 leaves the straight groove 3222 and rolls upward along the inclined groove 3221, the elastic force of the compression spring 3231 is gradually released. The elastic force of the compression spring 3231 drives the movable frame 322 to slide along the guide rod 323. Similarly, the three chucks 3271 move synchronously in the direction away from the center of the annular cylinder 321. The chucks 3271 release the clamping and fixing of the pipe and return to the initial position. Then, the conveyor roller 2 conveys the high ring stiffness impact-resistant pipe again, repeating the above steps, and so on.

[0035] In summary, the sequential control of the cutting action and the clamping action on the outer wall of the pipe is achieved through the linkage design of the cutting component 31 and the positioning component 32. When the hydraulic equipment drives the cutting component 31 to move downward, the roller 315 first rolls along the inclined groove 3221, driving the movable frame 322 to slide horizontally, which in turn causes the rotating plate 325 to rotate. The guide groove 3251 on it forces the three chucks 3271 to move synchronously towards the center, clamping the pipe evenly from the outside. During this process, the synchronous radial movement of the three chucks 3271 ensures that the clamping force is evenly distributed, avoiding the indentation or delamination of the pipe wall caused by local force in ordinary clamping mechanisms. This is especially suitable for multi-layer composite structures of high ring stiffness impact-resistant pipes. In addition, when the roller 315 enters the straight groove 3222, the position of the chucks 3271 is locked, and the clamping force remains constant. At the same time, the support mechanism 4 supports the pipe wall from the inside. The synchronous fixation inside and outside effectively offsets the radial cutting force during cutting, solving the problems of pipe end out-of-roundness and excessive ellipticity. In addition, after the cutting is completed, the hydraulic equipment drives the cutting component 31 to move upward. When the roller 315 moves upward along the straight groove 3222, the clamping force remains unchanged until it enters the inclined groove 3221, where it automatically resets under the elastic force of the compression spring 3231. The entire clamping and releasing process does not require additional power or manual intervention, and the sequence is accurate and the reliability is high, which improves the level of automation and processing consistency.

[0036] Reference Figures 1 to 8 The support mechanism 4 includes an electric slide rail 41 and a sliding plate 42. The electric slide rail 41 is used to pull the sliding plate 42 to move horizontally and linearly. A stabilizing frame 43 is fixedly connected to the top of the sliding plate 42. A cylinder 44 is fixedly installed on the top of the stabilizing frame 43. A sleeve 46 is also fixedly installed on the stabilizing frame 43. A connecting rod 45 is fixedly connected to the output end of the cylinder 44. One end of the connecting rod 45 passes through the sleeve 46. A telescopic component 47 is provided on the outside of the sleeve 46. The telescopic component 47 can automatically move forward and backward through the electric slide rail 41, and can be accurately inserted into the inner cavity of the pipe without manual intervention, thus improving positioning efficiency and automation level.

[0037] Multiple telescopic components 47 are evenly arranged. Each telescopic component 47 includes a support plate 471, a first connecting rod 472, a second connecting rod 473, and a third connecting rod 474. One end of the first connecting rod 472 is hinged to the support plate 471, and the other end is hinged to the outside of the sleeve 46. One end of the second connecting rod 473 is hinged to the support plate 471, and the other end is hinged to the outside of the sleeve 46. One end of the third connecting rod 474 is hinged to the support plate 471, and the other end is hinged to one end of the connecting rod 45. The use of multiple sets of connecting rod hinge structures allows multiple support plates 471 to expand radially outward simultaneously, providing a large and circumferentially uniform supporting force, effectively preventing the inner wall from collapsing or becoming out of round during pipe cutting.

[0038] In use, the electric slide rail 41 can pull the sliding plate 42 to move towards the mounting bracket 1. The movement of the sliding plate 42 drives the stabilizing bracket 43 to move synchronously. The movement of the stabilizing bracket 43 drives the sleeve 46 and the telescopic component 47 to be inserted into one end of the pipe as a whole. Then, the output end of the cylinder 44 extends, and the connecting rod 45 moves synchronously under the drive of the cylinder 44. While the connecting rod 45 moves, under the cooperation of the first connecting rod 472, the second connecting rod 473 and the third connecting rod 474, multiple support plates 471 move synchronously in the direction away from the sleeve 46. The multiple support plates 471 support and fix the inner side of the pipe. After the blade 312 completes the cutting of the pipe, the electric slide rail 41 pulls the sliding plate 42 to move away from the mounting bracket 1. The cut pipe also moves synchronously away from the mounting bracket 1. Then, the output end of the cylinder 44 shortens. Similarly, multiple support plates 471 move synchronously towards the sleeve 46. The multiple support plates 471 release the support and fixation on the inside of the cut pipe, and the operator can then remove the cut pipe.

[0039] In summary, the automatic advance and retreat of the telescopic component 47 is achieved through the cooperation of the electric slide rail 41, the sliding plate 42, and the stabilizing frame 43. This allows for precise insertion into the pipe cavity without manual intervention, improving operational efficiency and positioning consistency. Furthermore, the connecting rod 45 is driven by a cylinder 44, and through the hinged linkage of multiple sets of connecting rods 472, 473, and 474, multiple support plates 471 can synchronously and uniformly expand radially outward, pressing the pipe wall tightly from the inside. Compared to traditional airbags or single-point supports, this linkage-type telescopic structure has advantages such as high support force, high rigidity, and controllable stroke. It is suitable for large-diameter, thick-walled, high-ring-stiffness pipes and can effectively prevent pipe end collapse or out-of-roundness caused by radial cutting forces during cutting, ensuring the true roundness of the pipe cross-section. In addition, the number of support plates 471 can be flexibly set to ensure uniform distribution of support force along the circumference, avoiding localized stress concentration that could damage the inner wall of the pipe—a multi-layered composite structure. After cutting, the electric slide rail 41 directly pulls the sliding plate 42 to remove the cut pipe section. At the same time, the cylinder 44 retracts, causing the support plate 471 to automatically close, achieving synchronized action of material cutting and support release, simplifying the operation process. The entire support mechanism 4 and motion mechanism 3 work together to form a fully automatic cycle of external clamping, internal support, cutting, and removal, improving the dimensional consistency and production efficiency of batch processing, while reducing the labor intensity of operators, providing a reliable internal wall support solution for the precision forming of high ring stiffness impact-resistant pipes.

[0040] The working principle of this invention: The conveying roller 2 conveys the high-ring stiffness impact-resistant pipe and pulls the pipe through the annular cylinder 321. When the pipe moves to the preset position, the conveying roller 2 stops conveying, and the hydraulic equipment drives the cutting assembly 31 to move downward as a whole through the connector 313. During this process, the roller 315 of the cutting assembly 31 first rolls downward along the inclined groove 3221. When the roller 315 rolls along the inclined groove 3221, due to the compression of the roller 315, the movable frame 322 slides along the guide rod 323, compressing the spring. Spring 3231 gradually stretches and increases elasticity. Movable frame 322 moves and drives gear 324 to rotate around its own axis through rack 328. Gear 324 rotates and drives rotating plate 325 to rotate around its own axis through gear ring 326. During the rotation of rotating plate 325, with the cooperation of guide groove 3251 and guide post 3273, chuck 3271 slides along sliding rod 3272, and the three chucks 3271 move synchronously towards the center of annular cylinder 321, clamping and fixing the pipe.

[0041] Afterwards, the roller 315 leaves the inclined groove 3221 and rolls down along the straight groove 3222. During this process, the position of the chuck 3271 remains unchanged, and the chuck 3271 keeps the pipe clamped and fixed.

[0042] At the same time, the electric slide rail 41 pulls the sliding plate 42 to move towards the mounting bracket 1. The sliding plate 42 moves and drives the stabilizing bracket 43 to move synchronously. The stabilizing bracket 43 moves and drives the sleeve 46 and the telescopic component 47 to be inserted into one end of the pipe as a whole. Then, the output end of the cylinder 44 extends, and the connecting rod 45 moves synchronously under the drive of the cylinder 44. While the connecting rod 45 moves, under the cooperation of the first connecting rod 472, the second connecting rod 473 and the third connecting rod 474, multiple support plates 471 move synchronously in the direction away from the sleeve 46. The multiple support plates 471 support and fix the inner side of the pipe.

[0043] Afterwards, the cutting assembly 31 continues to move downwards as a whole, the roller 315 continues to roll downwards along the straight groove 3222, and the blade 312, which rotates under the drive of the power device 314, passes through the pipe and cuts the pipe.

[0044] Afterwards, the electric slide rail 41 pulls the sliding plate 42 to move away from the mounting bracket 1, and the cut pipe also moves synchronously away from the mounting bracket 1. Then, the output end of the cylinder 44 shortens. Similarly, multiple support plates 471 move synchronously towards the sleeve 46. The multiple support plates 471 release the support and fixation on the inside of the cut pipe, and the workers can then remove the cut pipe.

[0045] Subsequently, the hydraulic equipment drives the cutting assembly 31 to move upward as a whole. During this process, the roller 315 of the cutting assembly 31 first rolls upward along the straight groove 3222. During this process, the position of the chuck 3271 remains unchanged. When the roller 315 leaves the straight groove 3222 and rolls upward along the inclined groove 3221, the elastic force of the compression spring 3231 is gradually released. The elastic force of the compression spring 3231 drives the movable frame 322 to slide along the guide rod 323. Similarly, the three chucks 3271 move synchronously in a direction away from the center of the annular cylinder 321. The chucks 3271 release the clamping and fixing of the pipe and return to the initial position.

[0046] Then, the conveyor roller 2 conveys the high ring stiffness impact-resistant pipe again, repeating the above steps, and so on.
