10. The method of using the dual-station ring rolling device for new energy wind power generation flanges as described in claim 9, characterized in that: Includes the following steps: S1. Clamp one side of the ring blank between the vertical roller (3) and two clamping rollers (4), and support the bottom of the ring blank with the movable support roller (73); S2. Start the hydraulic rod (9) to push the housing (2) inward along the first slide rail (26) so that the lower pressure roller (212) moves to the bottom of the ring blank and the upper pressure roller (211) is above the ring blank. Then start the cylinder (219) to push the upper pressure roller (211) downward until it contacts the ring blank. S3. Start the motor (5) to drive the drive shaft (6), the first flat bevel gear (217) and the second flat bevel gear (218) to rotate, thereby driving the first slanted bevel gear (214), the first slanted rotating shaft (213) and the upper pressure roller (211) to rotate, and driving the second slanted bevel gear (216), the second slanted rotating shaft (215) and the lower pressure roller (212) to rotate, thereby driving the ring blank to rotate through the upper pressure roller (211) and the lower pressure roller (212); S4. Start the hydraulic rod (9) again to pull the housing (2) outward. At the same time, start the cylinder (219) to push the upper pressure roller (211) downward. The first flat bevel gear (217) follows the upper pressure roller (211) and moves downward along the drive shaft (6) during rotation to expand and roll the ring blank. S5. After the ring blank is expanded, stop the motor (5) and continue to pull the housing (2) outward through the hydraulic rod (9) until the upper pressure roller (211) and the lower pressure roller (212) are separated from the ring blank. Then, push the push rod (78) along the slide groove (79) through the housing (2) so that the push rod (78) pulls the pressure plate (721), slide rod (72) and movable support roller (73) through the wire rope (77) until the movable support roller (73) is separated from the ring blank. Under the action of gravity, the ring blank slides down along the vertical roller (3) and falls onto the transverse support roller (83) of the second support member (8). S6. Restart the hydraulic rod (9) to push the housing (2) inward until the side grinding roller (223) contacts the outer ring surface of the ring blank, and the upper grinding roller (221) and lower grinding roller (222) contact the upper and lower surfaces of the ring blank. Restart the motor (5) to drive the drive shaft (6), the third flat bevel gear (226), the vertical bevel gear (225), and the transverse rotating shaft (224) to rotate, thereby driving the upper grinding roller (221) and lower grinding roller (222) to rotate. 22) Rotation: When the horizontal rotating shaft (224) located on the upper side rotates, it drives the spur gear (228) to rotate, thereby driving the side grinding roller (223) to rotate and polish the ring blank. After the grinding is completed, the hydraulic rod (9) is activated to push the housing (2) to move outward until the upper grinding roller (221) and the lower grinding roller (222) are separated from the ring blank. The upper pressure roller (211), the lower pressure roller (212) and the movable support roller (73) do not block the ring blank. Finally, the ring blank is taken out.
