9. The method for using the double-station ring rolling device for wind turbine flanges according to claim 1, characterized in that: The following steps are involved: S1. Place the ring material on the fixed plate (101), adjust the telescopic distance of the first telescopic rod (106), so that the rotating roller (102) in the fixed frame (108) contacts the surface of the ring material, and then use the first motor (103) to drive the sprocket (107) to rotate, so that the sprocket (107) drives the rotating roller (102) to rotate, thereby realizing the feeding operation of the ring material; S2. After the ring material is conveyed onto the placement plate (301), the first hydraulic rod (207) is retracted so that the clamping block (2012) is located in the inner ring of the ring material. After the four clamping blocks (2012) completely enter the inner ring of the ring material, the first hydraulic rod (207) is extended so that the second slider (2014) moves outward. At the same time, the turntable (2010) drives the four connecting rods (2011) to rotate synchronously, thereby extending the four connecting frames (2013). At this time, the clamping block (2012) contacts the inner wall of the ring material, and under the action of the spring (2016) in the sleeve (2015), the clamping block (2012) is tightly fitted with the inner wall of the ring material, so that the workpiece does not become loose. S3. After the clamping is completed, the second telescopic rod (205) is retracted, and the second motor (204) drives the screw rod (202) to rotate, so that the first slider (203) slides along the top of the inner wall of the support frame (201), and the second telescopic rod (205) is moved as a whole to the top of the shell (206), and the second telescopic rod (205) is extended so that the workpiece is sleeved on the side wall of the core shaft module (306). At this time, the first hydraulic rod (207) is retracted to release the pressure of the clamping block (2012) on the workpiece, and the shell (206) is retracted as a whole to prepare for the next conveying; S4. After the ring material falls on the core shaft module (306), the wind turbine flange is gradually rolled by the cooperation between the core shaft module (306) and the driving module (307). During the working process, the diameter of the flange ring is adjusted by the driving module (307), and the height of the flange ring is adjusted by the height adjustment module (305). At the same time, since the movable end of the height adjustment module (305) is fixedly connected to the first distance measuring module (3010), the height of the height adjustment module (305) can be calculated by the first distance measuring module (3010), thereby measuring the height of the flange ring, and the rotation angle of the adjustment module (308) is measured according to the angle measuring module (3012). At the same time, the distance between the core shaft module (306) and the driving module (307) can be detected by the second distance measuring module (3011), thereby realizing the measurement of the width of the flange ring. Finally, the data can be summarized to calculate the various dimensions of the flange ring; S5. After the flange ring is manufactured, the operations of S2, S3 and S1 are performed in sequence, and the manufactured flange ring can be placed in the conveying device (1) to realize automatic loading and unloading and hoisting.
