Description
Technical Field
[0001] The present invention relates to the technical field of processing annular accessories for wind power generation, and in particular to a core roller multi-station ring rolling machine for processing wind power flanges and a method for using the same. Background Art
[0002] As we all know, wind turbine flanges, as key connecting components of wind turbines, need to withstand huge loads and complex working conditions, and have extremely high requirements for dimensional accuracy, mechanical properties and surface quality. Ring rolling machining is the core process of its production. The ring blank is gradually formed through continuous rolling, which has the advantages of high material utilization, high production efficiency and good mechanical properties of the workpiece. Wind turbine flanges are usually large-size ring structures. The ring rolling machining process includes blank preparation, blank making, ring rolling and subsequent processing. The ring rolling machine works based on the theory of metal plastic deformation. The main roller provides power, the core roller applies radial pressure, the guide roller prevents deviation, and the signal roller controls the size. During rolling, the deformation uniformity needs to be controlled by adjusting parameters such as temperature, speed and feed rate.
[0003] Although the ring rolling machine in the prior art can process the ring parts in multiple stations based on the outer side of the core roller, it is limited by the large size and weight of the wind turbine flange. Therefore, when it is placed in the processing position for the core roller to be inserted into the inner side, the temporary platform for supporting the material and the ring material often collide. Since the plasticity of the material is extremely high and the strength decreases significantly at high temperature, the collision may cause local depression, and even plastic deformation or cracking with a slight external force, thereby affecting the quality of the ring. If the surface oxide layer is not peeled off immediately after processing, it is easy for the oxide layer to be rolled into the material in the subsequent process, causing defects. Based on the above-mentioned situation, we found that it is difficult for the existing ring rolling machine to avoid the above problems at the same time. Therefore, we proposed a multi-station ring rolling machine that can provide buffering and auxiliary lifting during loading and unloading, promote the natural cooling rate of the ring after rolling, and assist in the peeling of the surface oxide layer. Summary of the Invention
[0004] In response to the shortcomings of the existing technology, the present invention provides a core roller multi-station ring rolling machine for wind power flange processing and its use method, which has the advantages of being able to perform buffering and auxiliary lifting during loading and unloading, promote the natural cooling rate after ring rolling, and assist in the peeling of the surface oxide layer.
[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A core roller multi-station ring rolling machine for wind power flange processing, comprising a machine base, a core roller structure, a main roller, two rollers and a movable seat, wherein the core roller structure is installed on the top of the machine base through a lifting device, the main roller is installed on the inner side of the machine base through a driving device, and the two rollers are installed on the inner side of the machine base through an extrusion device. The movable seat is fixedly connected to the right side of the machine base, and two groups of tapered roller frames are installed on the inner side of the movable seat. A side seat is fixedly connected between the machine base and the movable seat, an auxiliary position is provided between the machine base and the movable seat, and a rear section assembly is installed on the top of the side seat; The auxiliary position includes an upper plate, a lower plate and a side cover. The lower plate is located at the bottom of the upper plate. A plurality of through holes are opened on the inner side of the upper plate. A plurality of ball bearings are movably connected to the inner side of the lower plate. The side cover is arranged on the outer side of the upper plate. A fan is provided at the bottom of the lower plate. An air duct is fixedly connected to the output end of the fan. The top of the air duct is connected to the bottom of the side cover.
[0006] The above technical solution is adopted, by setting up a machine base as a structural support, and placing the material at the bottom of the core roller structure when in use. After the core roller structure is inserted into the interior, the main roller approaches the material and contacts it, and the two sets of rollers approach the material through the extrusion device and rotate by rotation drive, thereby extruding the material to reduce the wall thickness and enlarge the size to form the required ring size. The main roller and the core roller structure dominate the radial expansion and wall thickness control, and the tapered roller assists in limiting the axial size and end face quality control. When loading and unloading materials, the auxiliary position can be lifted so that the material is initially lifted before entering the processing position. When the core roller structure, the main roller and the roller drive are processing, the auxiliary position is removed to facilitate the loading action. After the processing is completed, the auxiliary position can be raised again. At the same time, the lower plate is moved up along the upper plate so that the ball extends out from the through hole until the top of the ball contacts the material, and then the material is driven to rotate slowly. The bottom of the material is lifted by the ball to move smoothly, and at the same time, the fan blows in air through the air duct, and the air flow is supplied from the air duct to the position of the side cover. Then the air flow passes between the upper and lower plates, and finally blows out from the through hole and the gap between the ball to cool the bottom of the molded material. Due to the deformation of the material after molding, the contact area between its bottom and the auxiliary position is small, so the air flow will evenly take away the heat from its bottom, inner edge and outer edge, so as to achieve a uniform auxiliary cooling effect. The position where the ball contacts the material can also peel off the bottom oxide layer due to continuous movement contact and air flow blowing.
[0007] The present invention is further configured as follows: a plurality of sliding sleeves are fixedly connected to the positions of the inner side of the lower plate corresponding to the through holes, and the inner sides of the sliding sleeves are slidably connected to the balls.
[0008] By adopting the above technical solution, a sliding sleeve is provided for mounting the ball bearings, and the ball bearings can roll smoothly on the inner side of the sliding sleeve, thereby reducing friction during normal operation.
[0009] The present invention is further configured as follows: an electric cylinder is provided at the bottom of the lower plate, the telescopic end of the electric cylinder is fixedly connected to the lower plate, a connecting frame is fixedly connected to the bottom of the fixed end of the electric cylinder, a connecting ear is fixedly connected to the outer side of the upper plate, a shield is fixedly connected to the left side of the upper plate, and the right side of the shield is in contact with the lower plate.
[0010] By adopting the above technical solution, an electric cylinder is set up. When the lower plate needs to be lifted to expose the ball out of the through hole, the lower plate can be pushed upward by extending the electric cylinder. The connecting ears are used to assist in connecting the upper plate and the connecting frame. The shield plate can facilitate blocking the airflow to prevent overflow from between the upper plate and the lower plate.
[0011] The present invention is further configured as follows: the top of the connecting frame is fixedly connected to a short seat, the inner side of the short seat is slidably connected to a flat plate, the bottom of the flat plate is fixedly connected to a hard spring, the bottom of the hard spring and the bottom of the inner wall of the short seat are fixedly connected, the top of the flat plate is fixedly connected to a connecting rod, the outer side of the top of the connecting rod is movably connected to a long seat, the top of the long seat is fixedly connected to the connecting ear, and the top of the fan is fixedly connected to the connecting frame.
[0012] By adopting the above technical solution, a short seat is set to cooperate with the flat plate. When placing the material, the rigid contact may cause it to deform. Therefore, the entire material will first contact the upper plate when it is placed. After the upper plate is subjected to force, the connecting ears and long seats on the outside and the connecting rod inside will be pressed down in the vertical direction. At this time, the flat plate at the bottom of the connecting rod presses against the hard spring to deform to achieve a buffering effect, thereby reducing damage to the material.
[0013] The present invention is further configured as follows: the inner side of the long seat is filled with oil, the inner side of the long seat is fixedly connected to a sleeve, the inner side of the sleeve is provided with a narrow groove, the inner side of the sleeve is slidably connected to a piston plate, and the bottom of the piston plate is fixedly connected to the connecting rod.
[0014] By adopting the above technical solution, when the entire upper plate is impacted, due to the heavy material itself, in addition to the flat plate pressing against the hard spring to protect the material when it falls, the sleeve and piston plate inside the long seat will also be displaced relative to each other during the falling process. At this time, the piston plate will push the oil to flow along the inside of the narrow groove to achieve a damping and buffering effect, thereby protecting the material while avoiding damage caused by rigid collision between structures.
[0015] The present invention is further configured as follows: a reset spring is fixedly connected to the bottom of the long seat, the bottom of the reset spring is fixedly connected to the short seat, an oil seal is provided at the bottom of the long seat, and the inner side of the oil seal is slidably connected to the connecting rod.
[0016] By adopting the above technical solution, a reset spring is set. After the long seat and the short seat are displaced due to the impact on the top, the reset spring rebounds and resets to facilitate the restoration of the structure and push the material to reset at the same time.
[0017] The present invention is further configured as follows: the rear section assembly includes a mounting block, two first telescopic cylinders are provided at the bottom of the mounting block, the top of the fixed end of the front first telescopic cylinder is fixedly connected to the bottom of the mounting block, the bottom of the fixed end of the front first telescopic cylinder and the bottom of the fixed end of the rear first telescopic cylinder are respectively fixedly connected with a short plate and a wide plate, the bottoms of the short plate and the wide plate are both provided with an adjustment plate, the opposite sides of the two adjustment plates are provided with a driving motor, the opposite sides of the two adjustment plates are provided with a grinding wheel, the output end of the driving motor passes through the adjustment plate and is fixedly connected to the grinding wheel, the telescopic end of the front first telescopic cylinder passes through the short plate and is fixedly connected to the top of the front adjustment plate, the telescopic end of the rear first telescopic cylinder passes through the wide plate and is fixedly connected to the top of the rear adjustment plate.
[0018] By adopting the above technical solution, a mounting block is provided for mounting the rear section assembly on the side seat. After the ring rolling operation, if the surface oxide layer is difficult to fall off, the first telescopic cylinder can be extended along the mounting block. At this time, the outer edge of the grinding wheel on the inner side of the two sets of adjustments contacts the surface of the ring material, and is driven to rotate by a driving motor to perform preliminary grinding on its surface to promote the shedding of the oxide layer.
[0019] The present invention is further configured as follows: a second telescopic cylinder is fixedly connected to the front side of the short plate, and a telescopic end of the second telescopic cylinder passes through the short plate and is fixedly connected to the front side of the wide plate.
[0020] By adopting the above technical solution, when it is necessary to assist the inner and outer edges in removing the oxide layer, the second telescopic cylinder can be extended to extend the distance between the short plate and the wide plate, and make the ends of the two sets of grinding wheels contact the inner and outer walls of the annular material.
[0021] The present invention is further configured as follows: a horizontal guide rail is fixedly connected to the top of the side seat, a vertical guide rail is fixedly connected to the right side of the machine base, sliders are slidably connected to the inner sides of the horizontal guide rail and the vertical guide rail, screw rods are rotatably connected to the inner sides of the horizontal guide rail and the vertical guide rail, servo motors are installed on the outer sides of the horizontal guide rail and the vertical guide rail, the output end of the servo motor is fixedly connected to the screw rod, the right side of the slider inside the vertical guide rail is fixedly connected to the fan frame, and the bottom of the slider inside the horizontal guide rail is fixedly connected to the mounting block.
[0022] By adopting the above technical solution, by setting a horizontal guide rail in combination with a slider, when the horizontal position of the rear-section component needs to be adjusted, the external servo motor can be used to drive the screw rod to drive the rear-section component to move horizontally, and the vertical guide rail and the slider are combined. When the servo motor drives the screw rod to rotate, it will drive the entire auxiliary position to rise or fall in the vertical direction.
[0023] A method for using a core roller multi-station ring rolling machine for processing wind power flanges comprises the following steps: S1. The vertical guide rail drives the auxiliary station to rise to the appropriate height. When the wind turbine flange blank to be processed is placed on the upper plate, the elastic deformation of the hard spring and the oil damping buffer structure in the long seat absorb the impact of the blank's gravity, preventing the high-temperature blank from sinking or cracking due to rigid contact. After the blank is placed stably, the auxiliary station descends and evacuates the processing area via the vertical guide rail, ensuring that the core roller structure, main rollers, and rolling rollers can enter the rolling station smoothly. S2. After the ring rolling process is completed, the auxiliary position rises again, and the electric cylinder extends to push the lower plate upward, allowing the ball to pass through the upper plate through the through-hole to support the bottom of the flange. At the same time, the fan is started, and the air flow passes through the air duct, side cover and through-hole gaps to sweep the bottom, inner edge and outer edge of the flange, achieving uniform air cooling. The flange rotates slowly under the drive, and the dual effects of the rolling friction of the ball and the air flow sweeping initially peel off the bottom oxide layer; If the oxide layer has not completely fallen off, the horizontal guide rail drives the rear section assembly to move horizontally to the corresponding position of the flange. The first telescopic cylinder extends to allow the grinding wheel to contact the flange surface, and the drive motor drives the grinding wheel to rotate and grind. If the inner and outer walls need to be processed, the second telescopic cylinder extends to adjust the distance between the short and wide plates, so that the two sets of grinding wheels contact the inner and outer edges respectively and operate synchronously. After processing is completed, the components retract and reset, and the auxiliary position descends to complete the unloading.
[0024] Compared with the prior art, the present invention provides a core roller multi-station ring rolling machine for wind power flange processing and its use method, which has the following beneficial effects: The core roller multi-station ring rolling machine for wind power flange processing and its use method are characterized by providing a machine base as a structural support. When in use, the material is placed at the bottom of the core roller structure. After the core roller structure is inserted into the interior, the main roller approaches the material and contacts it. The two sets of rollers approach the material through an extrusion device and are driven to rotate by rotation, thereby extruding the material to reduce the wall thickness and enlarge the size to form a required ring size. The main roller and the core roller structure dominate the radial expansion and wall thickness control, and the tapered roller assists in limiting the axial size and end face quality control. When loading and unloading materials, the auxiliary position can be lifted so that the material is initially lifted before entering the processing position. The auxiliary position can be removed when the core roller structure, the main roller and the roller drive are processing to facilitate the loading action. After the processing is completed, it can be re- The auxiliary position is newly raised, and the lower plate is moved up along the upper plate, so that the ball extends out from the through hole until the top of the ball contacts the material, and then the material is driven to rotate slowly. The bottom of the material is lifted by the ball to move smoothly, and at the same time, the fan blows in air through the air duct, and the air flow is supplied from the air duct to the position of the side cover. Then the air flow passes between the upper and lower plates, and finally bulges out from the through hole and the gap between the ball to cool the bottom of the molded material. Due to the deformation of the material after molding, the contact area between its bottom and the auxiliary position is small, so the air flow will evenly take away the heat from its bottom, inner edge and outer edge, so as to achieve a uniform auxiliary cooling effect. The position where the ball contacts the material can also peel off the bottom oxide layer due to continuous movement contact, combined with air blowing. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] Example 1 See also Figures 1-6 A core roller multi-station ring rolling machine for wind power flange processing and its use method, including a machine base 1, a core roller structure 2, a main roller 3, two rollers 4 and a movable base 5, the core roller structure 2 is installed on the top of the machine base 1 through a lifting device, the main roller 3 is installed on the inner side of the machine base 1 through a driving device, the two rollers 4 are installed on the inner side of the machine base 1 through an extrusion device, the movable base 5 is fixedly connected to the right side of the machine base 1, two groups of tapered roller frames 6 are installed on the inner side of the movable base 5, a side seat 7 is fixedly connected between the machine base 1 and the movable base 5, an auxiliary position 8 is provided between the machine base 1 and the movable base 5, and a rear section component 9 is installed on the top of the side seat 7; The auxiliary station 8 includes an upper plate 81, a lower plate 82 and a side cover 83. The lower plate 82 is located at the bottom of the upper plate 81. A plurality of through holes 84 are opened on the inner side of the upper plate 81. A plurality of balls 85 are movably connected to the inner side of the lower plate 82. The side cover 83 is arranged on the outer side of the upper plate 81. A fan 86 is provided at the bottom of the lower plate 82. The output end of the fan 86 is fixedly connected to an air duct 87. The top of the air duct 87 is connected to the bottom of the side cover 83. By setting the machine base 1 as a structural support, the material is placed at the bottom of the core roller structure 2 when in use. After the core roller structure 2 is inserted into the interior, the main roller 3 approaches the material and contacts it. The two sets of rollers 4 approach the material through the extrusion device and rotate by rotation, thereby extruding the material to reduce the wall thickness and increase the size to form the required ring size. The main roller 3 and the core roller structure 2 dominate the radial expansion and wall thickness control, and the tapered roller assists in limiting the axial size and end face quality control. When loading and unloading materials, the auxiliary position 8 can be lifted so that the material is initially lifted before entering the processing position. When the core roller structure 2, the main roller 3 and the roller 4 drive the processing, the auxiliary position 8 is removed to facilitate the loading action. After the processing is completed, the auxiliary position 8 can be raised again, and the lower plate 8 is moved up along the upper plate 81 at the same time. 2. Make the ball 85 extend from the through hole 84 until the top of the ball 85 contacts the material, and then continue to drive the material to rotate slowly. The bottom of the material is lifted by the ball 85 to move smoothly, and at the same time, the fan 86 blows air into the air duct 87. The air flow is supplied from the air duct 87 to the position of the side cover 83, and then the air flow passes between the upper plate 81 and the lower plate 82, and finally bulges out from the gap between the through hole 84 and the ball 85 to perform air cooling on the bottom of the molded material. Due to the deformation of the material after molding, the contact area between its bottom and the auxiliary position 8 is small, so the air flow will evenly take away heat from its bottom, inner edge and outer edge, so as to achieve a uniform auxiliary cooling effect. The position where the ball 85 contacts the material can also play a role in peeling off the bottom oxide layer due to continuous movement contact and air purge.
[0029] Among them, the inner side of the lower plate 82 is fixedly connected to the position of the through hole 84 with a plurality of sliding sleeves 10, and the inner side of the sliding sleeve 10 is slidably connected to the ball 85. By setting the sliding sleeve 10, the ball 85 is installed, and the ball 85 can roll smoothly on the inner side of the sliding sleeve 10 to reduce friction during normal operation. The bottom of the lower plate 82 is provided with an electric cylinder 11, and the telescopic end of the electric cylinder 11 is fixedly connected to the lower plate 82. The bottom of the fixed end of the electric cylinder 11 is fixedly connected to the connecting frame 12, the outer side of the upper plate 81 is fixedly connected to the connecting ear 13, and the left side of the upper plate 81 is fixedly connected to the shield plate 14. The right side of the shield plate 14 contacts the lower plate 82. By setting the electric cylinder 11, when the lower plate 82 needs to be lifted to expose the ball 85 from the through hole 84, the electric cylinder 11 can be used to lift the lower plate 82. The cylinder 11 extends to push the lower plate 82 upward, and the connecting ear 13 is used to assist in connecting the upper plate 81 and the connecting frame 12. The shield 14 is provided to facilitate blocking the airflow to avoid overflow from between the upper plate 81 and the lower plate 82. The top of the connecting frame 12 is fixedly connected with a short seat 15, and the inner side of the short seat 15 is slidably connected with a flat piece 16. The bottom of the flat piece 16 is fixedly connected with a hard spring 17. The bottom of the hard spring 17 is fixedly connected to the bottom of the inner wall of the short seat 15. The top of the flat piece 16 is fixedly connected with a connecting rod 18, and the outer side of the top of the connecting rod 18 is movably connected with a long seat 19. The top of the long seat 19 is fixedly connected to the connecting ear 13, and the top of the fan 86 is fixedly connected to the connecting frame 12. By setting the short seat 15 in conjunction with the flat piece 16, when placing the material When the material is being loaded, the rigid contact may cause it to deform, so the entire material will first contact the upper plate 81 when it is placed. After the upper plate 81 is subjected to force, the connecting ear 13 and the long seat 19 on the outside and the connecting rod 18 inside will be pressed down in the vertical direction. At this time, the flat piece 16 at the bottom of the connecting rod 18 presses the hard spring 17 to deform to have a buffering effect, reducing damage to the material. The inside of the long seat 19 is filled with oil, and the inside of the long seat 19 is fixedly connected to the inside of the long seat 19. A narrow groove 21 is provided on the inside of the sleeve 20. The inside of the sleeve 20 is slidably connected to the piston piece 22. The bottom of the piston piece 22 is fixedly connected to the connecting rod 18. When the entire upper plate 81 is impacted, since the material itself is heavy, it will not only pass through when it falls. In addition to the flat piece 16 pressing against the hard spring 17 to protect the material, the sleeve 20 and the piston piece 22 inside the long seat 19 will also be displaced relative to each other during the falling process of the long seat 19. At this time, the piston piece 22 will push the oil to flow along the narrow groove 21 to achieve a damping and buffering effect, while protecting the material and avoiding damage caused by rigid collision between structures. The bottom of the long seat 19 is fixedly connected with a return spring 23, and the bottom of the return spring 23 is fixedly connected to the short seat 15. The bottom of the long seat 19 is provided with an oil seal, and the inner side of the oil seal is slidably connected to the connecting rod 18. By setting the return spring 23, after the top between the long seat 19 and the short seat 15 is displaced due to impact, the return spring 23 rebounds and resets to facilitate the restoration of the structure and push the material to reset at the same time.
[0030] The auxiliary position 8 is driven to rise as a whole by the vertical guide rail 26 to receive the wind turbine flange blank to be processed. When the blank is placed, it first contacts the surface of the upper plate 81. Its gravity presses the upper plate 81 and drives the long seat 19 downward through the connecting ear 13. The long seat 19 pushes the connecting rod 18 and the flat plate 16 to compress the hard spring 17 in the short seat 15, and uses the spring deformation to initially cushion the impact. At the same time, the piston plate 22 in the long seat 19 slides along the sleeve 20 to push the oil to flow slowly from the narrow groove 21 to form a hydraulic damping buffer, which further weakens the impact and prevents the blank from being dented or cracked due to rigid contact. After buffering, the reset spring 23 rebounds and drives the upper plate 81 and the blank to reset slightly to ensure accurate alignment. During the processing stage, the auxiliary position 8 descends and evacuates the processing area through the vertical guide rail 26. The lower plate 82 is in a low position under the contraction of the electric cylinder 11, and the ball bearing 85 is completed. It is fully housed in the sliding sleeve 10 without contacting the blank, and the baffle 14 fits the side of the lower plate 82 to close the gap and avoid interfering with the rolling process; in the post-processing stage, the auxiliary position 8 rises again, and the electric cylinder 11 extends to push the lower plate 82 upward so that the ball 85 passes through the through hole 84 of the upper plate 81 and extends out to contact the bottom of the formed flange to form a rolling support. After the fan 86 is started, the air flow is transported to the side cover 83 through the air duct 87, and then ejected upward through the gap between the upper plate 81 and the lower plate 82, the through hole 84 and the gap between the ball 85, evenly blowing the bottom, inner edge and outer edge of the flange to achieve rapid air cooling. At the same time, the flange rotates slowly under the drive, and the bottom and the ball 85 continue to roll in contact with the air flow to cooperate with the air flow blowing. The oxide scale is peeled off through the dual effects of mechanical friction and air flow impact. After the processing is completed, the electric cylinder 11 contracts to retract the ball 85, and the auxiliary position 8 is lowered as a whole to facilitate flange unloading.
[0031] Example 2 refer to Figures 1-9A core roller multi-station ring rolling machine for wind power flange processing also includes a rear section component 9, wherein the rear section component 9 includes a mounting block 91, and two first telescopic cylinders 92 are provided at the bottom of the mounting block 91. The top of the fixed end of the front first telescopic cylinder 92 is fixedly connected to the bottom of the mounting block 91, and the bottom of the fixed end of the front first telescopic cylinder 92 and the bottom of the fixed end of the rear first telescopic cylinder 92 are respectively fixedly connected with a short plate 93 and a wide plate 94. The bottoms of the short plate 93 and the wide plate 94 are both provided with adjustment plates 95. The opposite sides of the two adjustment plates 95 are both provided with drive motors, and the opposite sides of the two adjustment plates 95 are both provided with grinding wheels 96. The output end of the drive motor passes through The adjusting plate 95 is fixedly connected to the grinding wheel 96, the telescopic end of the front first telescopic cylinder 92 passes through the short plate 93 and is fixedly connected to the top of the front adjustment plate 95, and the telescopic end of the rear first telescopic cylinder 92 passes through the wide plate 94 and is fixedly connected to the top of the rear adjustment plate 95. The mounting block 91 is provided to mount the rear section assembly 9 on the side seat 7. After the ring rolling operation, if the surface oxide layer is difficult to fall off, the first telescopic cylinder 92 can be extended along the mounting block 91. At this time, the outer edge of the grinding wheel 96 on the inner side of the two sets of adjustment handles contacts the surface of the ring material, and is driven to rotate by a driving motor to perform preliminary grinding on its surface to promote the shedding of the oxide layer.
[0032] Among them, the front side of the short plate 93 is fixedly connected to the second telescopic cylinder 24, the telescopic end of the second telescopic cylinder 24 passes through the short plate 93 and is fixedly connected to the front side of the wide plate 94. When it is necessary to assist the inner and outer edges to separate the oxide layer, the second telescopic cylinder 24 can be extended to extend the distance between the short plate 93 and the wide plate 94, and make the ends of the two sets of grinding wheels 96 contact the inner and outer walls of the annular material. The top of the side seat 7 is fixedly connected to the horizontal guide rail 25, and the right side of the machine base 1 is fixedly connected to the vertical guide rail 26. The inner sides of the horizontal guide rail 25 and the vertical guide rail 26 are slidably connected to the slider 27, and the inner sides of the horizontal guide rail 25 and the vertical guide rail 26 are both rotated The horizontal guide rail 25 and the vertical guide rail 26 are dynamically connected with a screw rod, and servo motors are installed on the outside of the horizontal guide rail 25 and the vertical guide rail 26. The output end of the servo motor is fixedly connected to the screw rod, and the right side of the slider 27 inside the vertical guide rail 26 is fixedly connected to the fan 86 frame. The bottom of the slider 27 inside the horizontal guide rail 25 is fixedly connected to the mounting block 91. By setting the horizontal guide rail 25 to cooperate with the slider 27, when it is necessary to adjust the horizontal position of the rear section component 9, the screw rod can be driven by an external servo motor to drive the rear section component 9 to move horizontally, and the vertical guide rail 26 and the slider 27 cooperate. When the servo motor drives the screw rod to rotate, it will drive the entire auxiliary position 8 to lift or lower in the vertical direction.
[0033] After the ring rolling operation is completed, if the oxide layer on the surface of the wind turbine flange is difficult to peel off naturally through air cooling and friction of the ball bearing 85, the servo motor on the outside of the horizontal guide rail 25 drives the screw to rotate, driving the slider 27 and the mounting block 91 to move horizontally, and accurately positioning the rear section component 9 to the flange processing area; then, the first telescopic cylinders 92 on the front and rear sides extend synchronously, pushing the adjustment plate 95 and the grinding wheel 96 close to the flange, so that the outer edge of the grinding wheel 96 contacts the flange surface, and the driving motor drives the grinding wheel 96 to rotate at high speed to remove the surface oxide layer through mechanical friction; if the flange needs to be processed The inner and outer walls, the second telescopic cylinder 24 extends, pushing the wide plate 94 away from the short plate 93, so that the ends of the two sets of grinding wheels 96 contact the inner and outer edges of the flange at the same time, realizing multi-surface synchronous processing; during the oxide layer treatment process, the servo motor on the outside of the vertical guide rail 26 drives the slider 27 to rise and fall through the screw rod, so that the auxiliary position 8 rises to the height of the ball 85 supporting the flange, ensuring that the flange remains stable during slow rotation and cooperates with the grinding wheel 96 to operate; after the treatment is completed, each telescopic cylinder retracts and resets, the rear section component 9 returns horizontally to the standby position, the auxiliary position 8 drops, and the entire system returns to its initial state.

10. A method for using a core roller multi-station ring rolling machine for wind power flange processing according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. The vertical guide rail (26) drives the auxiliary position (8) to rise to the appropriate height as a whole. When the wind turbine flange blank to be processed is placed on the upper plate (81), the elastic deformation of the hard spring (17) and the oil damping buffer structure in the long seat (19) are used to absorb the impact of the gravity of the blank, thereby preventing the high-temperature blank from being dented or cracked due to rigid contact. After the blank is placed stably, the auxiliary position (8) is lowered and evacuated from the processing area through the vertical guide rail (26), ensuring that the core roller structure (2), the main roller (3) and the rolling roller (4) can smoothly enter the rolling station; S2. After the ring rolling process is completed, the auxiliary position (8) rises again, and the electric cylinder (11) extends to push the lower plate (82) upward, so that the ball (85) passes through the through hole (84) of the upper plate (81) to support the bottom of the flange.

After the processing is completed, each component retracts and resets, and the auxiliary position (8) descends to complete the unloading.
