Description
Technical Field
[0001] This invention relates to the field of wind turbine flange processing equipment technology, specifically a large-scale wind turbine flange annular shaping device. Background Technology
[0002] Large wind turbine flanges are key connecting structural components between the tower, hub, and blades of wind turbine generator sets. Wind turbine flanges can be divided into tower flanges, base flanges, generator flanges, and pitch frame flanges. The tower flange mainly connects the tower to the blade shaft and bears the huge bending moment generated by the rotation of the blades; the base flange connects the tower base to the tower and bears the wind turbine itself and the force of the wind; the generator flange connects the generator to the blade shaft and bears the weight and rotational torque of the generator; the pitch frame flange connects the pitch frame to the blade shaft and mainly controls the angle and speed of the blades.
[0003] After being ring-forged, wind turbine flanges typically require shaping. A common shaping method involves using multiple sets of rollers to simultaneously press the inner and outer diameters of the flange as it rotates. However, during the cooling process from a high temperature, the residual stress inside the ring-forged flange is gradually released, which may cause the flange to form an irregular ellipse. Since the multiple sets of rollers are usually arranged at preset intervals according to a perfect circular outline, the irregular shape of the flange may cause a single roller to press the flange while the rollers in other positions do not make sufficient contact with the flange, resulting in flange misalignment. Continuous pressing may cause the flange to become increasingly misaligned, affecting the shaping of the flange. Summary of the Invention
[0004] To solve the above technical problems, the present invention provides a large wind power flange ring shaping device, including a support platform, three mounting platforms fixedly connected to the top of the support platform, friction rollers rotatably connected to the top of each of the three mounting platforms, and pulley sets fixedly connected to the side walls of each of the three friction rollers. Each of the three mounting platforms has a drive motor fixedly connected to its inner wall, and the output ends of each of the three drive motors are fixedly connected to the side wall of the pulley assembly. The system also includes: The shaping mechanism is slidably mounted on the top of the support platform; A support mechanism is slidably mounted on top of the support platform; The adapter mechanism is fixedly installed on the inner wall of the support platform. In operation, the operator uses external hoisting equipment to lift the wind turbine flange to be shaped and move it to the top of the friction roller. Then, the wind turbine flange is placed on top of the friction roller. After placement, the drive motor is started to drive the pulley set to rotate, which in turn drives the friction roller to rotate. The friction between the friction roller and the flange causes the flange to rotate slowly.
[0005] Preferably, the shaping mechanism includes: A drive component is slidably mounted on top of the support platform; The extrusion assembly is slidably disposed on the inner wall of the drive assembly; Once the flange is in place, the extrusion assembly is driven by the drive assembly to move toward the flange.
[0006] Preferably, the support mechanism includes: The push component is slidably mounted on top of the support platform via a slider; The top of the support platform is slidably connected to six sliding blocks, and each of the six sliding blocks is slidably connected to a pusher frame on its inner wall. The synchronization component is fixedly mounted on the top of the support platform by fasteners; The fasteners include a manifold that is fixedly connected to the top of the support platform; When the extrusion component moves, it drives the pushing component to move, and the pushing component will first contact the flange.
[0007] Preferably, the adapter includes: A rotating assembly is fixedly installed on the inner wall of the support platform; A shifting assembly is rotatably mounted on top of the support platform; In use, the rotating component is activated to drive the shifting component to rotate, which in turn drives the extrusion component to move, thus adjusting the distance between the extrusion components.
[0008] Preferably, the drive assembly includes three sliding platforms slidably disposed on the top of the support platform, and two hydraulic cylinders are fixedly connected to the inner wall of each of the three sliding platforms.
[0009] Preferably, the extrusion assembly includes two roller frames slidably connected to the inner wall of the sliding table, extrusion rollers are rotatably connected to the inner walls of the six roller frames, and the output end sidewalls of the six hydraulic cylinders are fixedly connected to the sidewalls of the six roller frames. Once the wind turbine flange is in place, the hydraulic cylinder is extended to push the roller frame toward the flange, bringing the compression rollers closer to the flange.
[0010] Preferably, the pushing assembly includes six roller frames disposed on the top of the support platform, and piston plates are fixedly connected to the side walls of each of the six roller frames; The top of each of the six sliding blocks is fixedly connected to a hydraulic sleeve, the outer wall of each of the six piston plates is slidably connected to the inner wall of each of the six hydraulic sleeves, and the inner wall of each of the six hydraulic sleeves is provided with hydraulic oil. The six push frames are arranged in groups of three, and the side walls of the three push frames are fixedly connected to the side walls of the three roller frames near the outer wall of the manifold. The outer walls of the six piston plates are fixedly connected with a sealing ring to enhance their sealing performance. When the roller frame near the manifold moves, it drives the push frame to move, which in turn pushes the sliding block toward the flange, causing the hydraulic sleeve and roller frame to move. As the roller frame continues to move, it pushes the roller frame to contact the flange first.
[0011] Preferably, the synchronization component includes a spring plate slidably connected to the inner wall of the manifold, and six infusion tubing is connected through the inner wall of the manifold. Hydraulic oil is installed on the inner wall of the manifold. The outer walls of the six infusion hoses are all connected to the inner walls of the six hydraulic sleeves. The spring plate is normally in a compressed state, and a sealing ring is fixedly connected to the outer wall of the spring plate. Among them, sealing ring 2 is used to enhance the sealing between the spring plate and the manifold. After the roller frame contacts the flange, the spring plate is in a compressed state and the hydraulic sleeve is connected to the manifold through the infusion hose. The squeezing force of the spring plate will be transmitted to the position of the piston plate through hydraulic oil 1 and hydraulic oil 2, increasing the pushing force of the roller frame. When some roller frames are in contact with the flange and the remaining roller frames are not in contact with the flange, the roller frame will push the flange to move, change the position of the flange, and cause the remaining roller frames to contact the flange, adjusting the rotation center of the flange to align with the center of the manifold. The center of the manifold is the center of the circumferential distribution of multiple push frames. When multiple roller frames are in contact with the flange, the roller frames will stop moving due to the obstruction of the flange. The sliding block continues to move, which will cause hydraulic oil 1 in the hydraulic sleeve to be squeezed by the piston plate, so that some hydraulic oil 1 enters the manifold through the infusion hose and mixes with hydraulic oil 2. Hydraulic oil 2 will then squeeze the spring plate, increasing its rebound force and increasing the squeezing force of the roller frame on the flange. When the flange rotates, when the protruding part of the flange contacts part of the roller frame, the flange will squeeze the roller frame to move, allowing the roller frame to squeeze hydraulic oil into the manifold and squeeze the spring plate to descend. When the concave part of the flange contacts the roller frame, the roller frame has room to move, the spring plate will release part of the rebound force, and squeeze hydraulic oil into the hydraulic sleeve, pushing the roller frame to squeeze the flange. This makes it difficult for the center of the flange to deviate from the center of the manifold when the flange rotates. As the extrusion rollers continue to move, multiple extrusion rollers will come into contact with the flange, extruding the inner and outer diameters of the flange, causing the flange to deform and forcing the flange shape to approach a perfect circle from an irregular ellipse. This reshapes the flange and solves the problem of the flange's rotation center deviating when the flange rotates, improving the roundness of the flange and making the flange shape more regular. After the roller frame contacts the flange, as it continues to move towards the inner wall of the flange, it increases the squeezing force of the roller frame on the flange. When the squeezing roller squeezes the protruding part of the flange, it causes slight deformation in some areas of the flange, causing some recessed parts of the flange to expand slightly outward. At this time, the squeezing force between the roller frame and the flange at some of the recessed parts of the flange will decrease. Then, the spring plate will release some of the rebound force, squeezing hydraulic oil 2 into the hydraulic sleeve and mixing with hydraulic oil 1, allowing hydraulic oil 1 to squeeze the roller frame, increasing the squeezing force of the roller frame on the recessed part of the flange, increasing the support force on the flange, and suppressing the elastic rebound of the flange. This effectively prevents the small squeezing amplitude of the protruding part of the flange each time when the squeezing roller gradually increases the squeezing force on the flange. When the squeezing roller separates from this position, the flange is prone to rebound, increasing the difficulty of shaping.
[0012] Preferably, the rotating assembly includes a servo motor fixedly connected to the top of the inner wall of the support platform, a bevel gear rotatably connected to the inner wall of the support platform, and the top of the output end of the servo motor fixedly connected to the bottom of the bevel gear rotatably connected.
[0013] Preferably, the displacement assembly includes three threaded rods rotatably connected to the top of the support platform, and three bevel gears are provided on the top of the support platform. The outer walls of the three threaded rods are threadedly connected to the outer walls of the three sliding platforms. The side walls of the three bevel gears are all fixedly connected to the side walls of the three threaded rods, and the outer walls of the three bevel gears are all meshed with the outer walls of the bevel gears. When flanges of different sizes need to be shaped, the servo motor is started to drive the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, causing the second bevel gear to rotate, which in turn drives the threaded rod to rotate. When the threaded rod rotates, it pushes the sliding table to move, which in turn drives the roller frame and the extrusion roller to move. The push frame pulls the sliding block to move, adjusting the distance between multiple sliding tables and increasing or decreasing the spacing between multiple sets of extrusion rollers, thereby adapting to flanges of various sizes and enhancing their versatility.
[0014] The present invention has the following beneficial effects: (1) When using this invention, the operator uses an external hoisting device to hoist the wind turbine flange to be shaped to the top of the friction roller. The hydraulic cylinder is activated to extend and push the roller frame towards the flange, so that the pusher pushes the roller frame to contact the flange first. Through the pusher and synchronization components, multiple roller frames are made to contact the flange, and the rotation center of the flange is adjusted to align with the center of the manifold. At the same time, the flange is supported so that when the flange rotates, the center of the flange is difficult to deviate from the center of the manifold. As the extrusion rollers continue to move, multiple extrusion rollers will contact the flange, extruding the inner and outer diameters of the flange, causing the flange to deform and forcing the flange shape to approach a perfect circle from an irregular ellipse. This shapes the flange and solves the problem that the rotation center of the flange will deviate when the flange rotates, improving the roundness of the flange and making the flange shape more regular.
[0015] (2) When the extrusion roller is not in contact with the flange, the present invention aligns the rotation center of the flange with the center of the manifold. When the extrusion roller moves toward the flange, the extrusion pressure on the flange protrusion will gradually increase during the movement of the extrusion roller, thereby reducing the local deformation of the flange and reducing the extrusion pressure on the flange protrusion after the extrusion roller is in contact with the flange. This effectively prevents the flange surface from being damaged by the extrusion roller when the flange protrusion is in contact with the extrusion roller after the extrusion roller is in contact with the flange.
[0016] (3) After the roller frame contacts the flange, as the roller frame continues to move toward the inner wall of the flange, it will increase the squeezing force of the roller frame on the flange. When the squeezing roller squeezes the protruding position of the flange, it will cause a slight deformation in a part of the flange, and cause a slight outward expansion of a part of the recessed position of the flange. The spring plate will release part of the rebound force, increase the squeezing force of the roller frame on the recessed position of the flange, increase the support force on the flange, and suppress the elastic rebound of the flange. This effectively prevents the small squeezing amplitude of the protruding position of the flange each time when the squeezing roller gradually increases the squeezing force on the flange. When the squeezing roller separates from this position, the flange is prone to rebound, increasing the difficulty of shaping.
[0017] (4) When different sizes of flanges need to be shaped, the present invention starts the servo motor and drives the threaded rod to rotate through the displacement component, which will push the sliding table to move, thereby driving the roller frame and the extrusion roller to move, increasing or decreasing the distance between multiple sets of extrusion rollers, thereby adapting to flanges of various sizes and enhancing their versatility. In addition, by gradually increasing the extrusion pressure on the flange protrusion position by the extrusion roller, the friction force between the two is small each time they come into contact, which effectively prevents the extrusion roller from applying too much extrusion pressure to the flange when extruding the flange protrusion position, resulting in excessive friction between the two and affecting the smooth rotation of the flange.

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.
[0022] Example 1, please refer to Figures 1-4 The present invention is a large wind turbine flange ring shaping device, including a support platform 13, three mounting platforms 14 fixedly connected to the top of the support platform 13, friction rollers 15 rotatably connected to the top of each of the three mounting platforms 14, and pulley sets 17 fixedly connected to the side walls of each of the three friction rollers 15. Each of the three mounting platforms 14 has a drive motor 16 fixedly connected to its inner wall, and the output ends of the three drive motors 16 are fixedly connected to the side wall of the pulley assembly 17. The assembly also includes: Shaping mechanism 1 is slidably disposed on the top of support platform 13; Support mechanism 2 is slidably mounted on the top of support platform 13; The adapter mechanism 3 is fixedly installed on the inner wall of the support platform 13. In operation, the operator uses external hoisting equipment to lift the wind turbine flange to be shaped and move it to the top of the friction roller 15. Then, the wind turbine flange is placed on top of the friction roller 15. Figure 2 As shown in the position of G, after placement, the drive motor 16 is started to drive the pulley group 17 to rotate, which in turn drives the friction roller 15 to rotate. Through the friction between the friction roller 15 and the flange, the flange is driven to rotate slowly.
[0023] Plastic surgery facility 1 includes: Drive component 11 is slidably disposed on the top of support platform 13; The extrusion assembly 12 is slidably disposed on the inner wall of the drive assembly 11; Once the flange is in place, the extrusion assembly 12 is pushed by the drive assembly 11 to move toward the flange.
[0024] Supporting mechanism 2 includes: Push component 21 is slidably mounted on top of support platform 13 via a slider; The top of the support platform 13 is slidably connected to six sliding blocks 211, and the inner walls of the six sliding blocks 211 are slidably connected to push frames 212; Synchronization component 22 is fixedly mounted on the top of support platform 13 by fasteners; The fasteners include a manifold 221 that is fixedly connected to the top of the support platform 13; When the extrusion component 12 moves, it will drive the push component 21 to move, and the push component 21 will first contact the flange.
[0025] The third compatible organization includes: Rotating component 31 is fixedly installed on the inner wall of support platform 13; The shifting component 32 is rotatably mounted on the top of the support platform 13; In use, the rotating component 31 is activated to drive the shifting component 32 to rotate, thereby moving the extrusion component 12 and adjusting the distance between the extrusion components 12.
[0026] Example 2, please refer to Figures 3-9 The present invention is a large wind turbine flange ring shaping device. Based on Example 1, the drive assembly 11 includes three sliding tables 111 slidably disposed on the top of the support platform 13, and two hydraulic cylinders 112 are fixedly connected to the inner wall of each of the three sliding tables 111.
[0027] The extrusion assembly 12 includes two roller frames 121 slidably connected to the inner wall of the slide table 111, extrusion rollers 122 rotatably connected to the inner walls of the six roller frames 121, and the output end sidewalls of the six hydraulic cylinders 112 are fixedly connected to the sidewalls of the six roller frames 121. After the wind turbine flange is placed in place, the hydraulic cylinder 112 is activated to extend and push the roller frame 121 toward the flange, so that the pressing roller 122 approaches the flange.
[0028] The pushing assembly 21 includes six roller frames 214 disposed on the top of the support platform 13, and piston plates 215 are fixedly connected to the side walls of the six roller frames 214. The top of each of the six sliding blocks 211 is fixedly connected to a hydraulic sleeve 213, the outer wall of each of the six piston plates 215 is slidably connected to the inner wall of each of the six hydraulic sleeves 213, and hydraulic oil is provided on the inner wall of each of the six hydraulic sleeves 213. The six pushers 212 are arranged in groups of three, and the side walls of the three pushers 212 are fixedly connected to the side walls of the three roller frames 121 near the outer wall of the manifold 221. The outer walls of the six piston plates 215 are fixedly connected with sealing rings to enhance their sealing performance. When the roller frame 121 near the manifold 221 moves, it will drive the push frame 212 to move, causing the push frame 212 to push the sliding block 211 to move towards the flange, which in turn drives the hydraulic sleeve 213 and the roller frame 214 to move. As the roller frame 121 continues to move, it will push the roller frame 214 to contact the flange first.
[0029] The synchronization component 22 includes a spring plate 222 that is slidably connected to the inner wall of the manifold 221, and six infusion tubing 223 are connected through the inner wall of the manifold 221. Hydraulic oil is installed on the inner wall of the manifold 221. The outer walls of the six infusion hoses 223 are all connected to the inner walls of the six hydraulic sleeves 213. The spring plate 222 is normally in a compressed state. A sealing ring is fixedly connected to the outer wall of the spring plate 222. Among them, the second sealing ring is used to enhance the sealing between the spring plate 222 and the manifold 221. After the roller frame 214 contacts the flange, the spring plate 222 is in a compressed state, and the hydraulic sleeve 213 is connected to the manifold 221 through the infusion hose 223. The compressive force of the spring plate 222 is transmitted to the position of the piston plate 215 through hydraulic oil one and hydraulic oil two, increasing the pushing force of the roller frame 214. When part of the roller frame 214 contacts the flange, and the remaining roller frames 214 do not contact the flange, the roller frame 214 will push the flange to move, change the position of the flange, and cause the remaining rollers to move. When the frame 214 contacts the flange, the rotation center of the flange is adjusted to align with the center of the manifold 221. The center of the manifold 221 is the center of the circumferential distribution of multiple push frames 212. When multiple roller frames 214 are in contact with the flange, the roller frames 214 will stop moving due to the obstruction of the flange. The sliding block 211 continues to move, which will cause the hydraulic oil in the hydraulic sleeve 213 to be squeezed by the piston plate 215. This will cause some of the hydraulic oil to enter the manifold 221 through the infusion hose 223 and mix with the hydraulic oil. The hydraulic oil will then squeeze the spring plate 222, increasing its rebound force and increasing the squeezing force of the roller frame 214 on the flange. When the flange rotates, when the protruding part of the flange contacts part of the roller frame 214, the flange will squeeze the roller frame 214 to move, allowing the roller frame 214 to squeeze hydraulic oil into the manifold 221 and squeeze the spring plate 222 to descend. When the concave part of the flange contacts the roller frame, the roller frame 214 has room to move, the spring plate 222 will release part of the rebound force, and squeeze hydraulic oil into the hydraulic sleeve 213, pushing the roller frame 214 to squeeze the flange. This makes it difficult for the center of the flange to deviate from the center of the manifold 221 when the flange rotates. As the extrusion rollers 122 continue to move, multiple extrusion rollers 122 will come into contact with the flange, extruding the inner and outer diameters of the flange, causing the flange to deform and forcing the flange shape to approach a perfect circle from an irregular ellipse. This reshapes the flange and solves the problem that the center of rotation of the flange will deviate when the flange rotates, improving the roundness of the flange and making the flange shape more regular. After the roller frame 214 contacts the flange, as the roller frame 121 continues to move towards the inner wall of the flange, the squeezing force of the roller frame 214 on the flange increases. When the squeezing roller 122 squeezes the protruding part of the flange, it causes a slight deformation in a part of the flange, causing a slight outward expansion of the recessed part of the flange. At this time, the squeezing force between the roller frame 214 and the flange at the recessed part of the flange will decrease. At this time, the spring plate 222 will release part of the rebound force, squeezing hydraulic oil 2 into the hydraulic sleeve 213 and mixing with hydraulic oil 1, allowing hydraulic oil 1 to squeeze the roller frame 214, increasing the squeezing force of the roller frame 214 on the recessed part of the flange, increasing the support force on the flange, and suppressing the elastic rebound of the flange. This effectively prevents the small squeezing amplitude of the protruding part of the flange each time the squeezing roller 122 gradually increases the squeezing force on the flange. When the squeezing roller 122 separates from this position, the flange is prone to rebound, increasing the difficulty of shaping.
[0030] The rotating assembly 31 includes a servo motor 311 fixedly connected to the top of the inner wall of the support platform 13, and a bevel gear 312 rotatably connected to the inner wall of the support platform 13. The top of the output end of the servo motor 311 is fixedly connected to the bottom of the bevel gear 312.
[0031] The shifting assembly 32 includes three threaded rods 322 rotatably connected to the top of the support platform 13. The top of the support platform 13 is provided with three bevel gears 321. The outer walls of the three threaded rods 322 are threadedly connected to the outer walls of the three sliding tables 111. The side walls of the three bevel gears 321 are fixedly connected to the side walls of the three threaded rods 322, and the outer walls of the three bevel gears 321 are meshed with the outer walls of the bevel gears 312. When flanges of different sizes need to be shaped, the servo motor 311 is started to drive the bevel gear 312 to rotate. The bevel gear 312 meshes with the bevel gear 321, causing the bevel gear 321 to rotate, which in turn drives the threaded rod 322 to rotate. When the threaded rod 322 rotates, it pushes the sliding table 111 to move, which in turn drives the roller frame 121 and the pressing roller 122 to move. The push frame 212 pulls the sliding block 211 to move, adjusting the distance between multiple sliding tables 111 and increasing or decreasing the distance between multiple sets of pressing rollers 122, thereby adapting to flanges of various sizes and enhancing their versatility.
[0032] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.
[0033] One specific application of this embodiment is as follows: When using this invention, the operator uses external hoisting equipment to lift the wind turbine flange to be shaped and move it to the top of the friction roller 15. Then, the wind turbine flange is placed on top of the friction roller 15, as shown below. Figure 2 As shown in the position of G, after placement, the drive motor 16 is started to drive the pulley group 17 to rotate, the pulley group 17 drives the friction roller 15 to rotate, and the friction between the friction roller 15 and the flange drives the flange to rotate slowly. Once the flange is in place, the hydraulic cylinder 112 extends and pushes the roller frame 121 toward the flange, causing the compression roller 122 to move. As the roller frame 121 moves closer to the manifold 221, it drives the push frame 212 to move, which in turn pushes the sliding block 211 toward the flange, causing the hydraulic sleeve 213 and the roller frame 214 to move. As the roller frame 121 continues to move, it pushes the roller frame 214 to contact the flange first. At this time, since the spring plate 222 is under compression and the hydraulic sleeve 213 is connected to the manifold 221 via the infusion hose 223, the compressive force of the spring plate 222 is transmitted to the position of the piston plate 215 through hydraulic oil one and hydraulic oil two, increasing the pushing force of the roller frame 214. When part of the roller frame 214 is in contact with the flange, and the remaining roller frames 214 are not in contact with the flange, the roller frames 214 will push the flange to move, change the position of the flange, and cause the remaining roller frames 214 to contact the flange, adjusting the rotation center of the flange to align with the manifold. The center of the manifold 221 is the center of the circle where multiple push frames 212 are distributed circumferentially. When multiple roller frames 214 are in contact with the flange, the roller frames 214 will stop moving due to the obstruction of the flange. The sliding block 211 continues to move, which will cause the hydraulic oil in the hydraulic sleeve 213 to be squeezed by the piston plate 215. This will cause some of the hydraulic oil to enter the manifold 221 through the infusion hose 223 and mix with the hydraulic oil. The hydraulic oil will then squeeze the spring plate 222, increasing its rebound force and increasing the squeezing force of the roller frame 214 on the flange. When the flange rotates, when the protruding part of the flange contacts part of the roller frame 214, the flange will squeeze the roller frame 214 to move, allowing the roller frame 214 to squeeze hydraulic oil into the manifold 221 and squeeze the spring plate 222 to descend. When the concave part of the flange contacts the roller frame, the roller frame 214 has room to move, the spring plate 222 will release part of the rebound force, and squeeze hydraulic oil into the hydraulic sleeve 213, pushing the roller frame 214 to squeeze the flange. This makes it difficult for the center of the flange to deviate from the center of the manifold 221 when the flange rotates. As the extrusion rollers 122 continue to move, multiple extrusion rollers 122 will come into contact with the flange, extruding the inner and outer diameters of the flange, causing the flange to deform and forcing the flange shape to approach a perfect circle from an irregular ellipse. This reshapes the flange and solves the problem that the center of rotation of the flange will deviate when the flange rotates, improving the roundness of the flange and making the flange shape more regular. When a circular flange rotates, the distance from the flange center should be equal at every point on the outer diameter and equal at every point on the inner diameter. In this specific application, the flange protrusion does not mean that there is a protrusion on the flange surface, but rather that the distance from the outer diameter to the flange center is the greatest when the flange rotates. Similarly, the recessed position does not mean that there is a recess on the flange surface, but rather that the distance from the inner diameter to the flange center is the smallest. Secondly, when the extrusion roller 122 is not in contact with the flange, the center of rotation of the flange is aligned with the center of the manifold 221. As the extrusion roller 122 moves towards the flange, due to the irregular shape of the flange, the protruding part of the flange will contact a portion of the extrusion roller 122. Figure 8 As shown by the positions of H, I, and J, the extrusion roller 122 will extrude the flange, causing the flange to deform. As the extrusion roller 122 moves, the extrusion force on the flange protrusion will gradually increase, reducing the local deformation of the flange and reducing the extrusion force on the flange protrusion after the extrusion roller 122 is in contact with the flange. This effectively prevents the flange surface from being damaged by excessive extrusion force when the flange protrusion comes into contact with the extrusion roller 122 after the extrusion roller 122 is in contact with the flange. Secondly, after the roller frame 214 contacts the flange, as the roller frame 121 continues to move towards the inner wall of the flange, the squeezing force of the roller frame 214 on the flange will increase. When the squeezing roller 122 squeezes the protruding part of the flange, it will cause a slight deformation in a part of the flange, and cause a slight outward expansion of a part of the recessed part of the flange. At this time, the squeezing force between the roller frame 214 and the flange at part of the recessed part of the flange will decrease. At this time, the spring plate 222 will release part of the rebound force, and the squeezing hydraulic oil 2 enters the hydraulic sleeve 213 and mixes with the hydraulic oil 1, allowing the hydraulic oil 1 to squeeze the roller frame 214, increasing the squeezing force of the roller frame 214 on the recessed part of the flange, increasing the support force on the flange, and suppressing the elastic rebound of the flange. This effectively prevents the small squeezing amplitude of the protruding part of the flange each time when the squeezing roller 122 gradually increases the squeezing force on the flange. When the squeezing roller 122 separates from this position, the flange is prone to rebound, increasing the difficulty of shaping. After the flange is shaped, the drive motor 16 is stopped to stop the flange from rotating. Then the hydraulic cylinder 112 is retracted to pull the roller frame 121 to move, so that the extrusion roller 122 is separated from the flange. At the same time, the push frame 212 pulls the sliding block 211 to move, so that the roller frame 214 is separated from the flange. The spring plate 222 will release part of the rebound force to return to its original position. Then, the flange is lifted and separated from the friction roller 15 by the hoisting equipment. Secondly, when flanges of different sizes need to be shaped, the servo motor 311 is started to drive the bevel gear 312 to rotate. The bevel gear 312 meshes with the bevel gear 321, causing the bevel gear 321 to rotate, which in turn drives the threaded rod 322 to rotate. When the threaded rod 322 rotates, it pushes the sliding table 111 to move, which in turn drives the roller frame 121 and the pressing roller 122 to move. The push frame 212 pulls the sliding block 211 to move, adjusting the distance between the multiple sliding tables 111 and increasing or decreasing the distance between the multiple sets of pressing rollers 122, thereby adapting to flanges of various sizes and enhancing their versatility. In addition, by gradually increasing the pressing force on the protruding part of the flange by the pressing roller 122, the friction between the two is reduced each time they come into contact. This effectively prevents the pressing roller 122 from applying excessive pressing force to the flange when pressing the protruding part of the flange, which would cause excessive friction between the two and affect the smooth rotation of the flange.
