Flange machine device capable of automatically overturning

The utility model relates to the technical field of flange machines, and discloses a flange machine device capable of automatically overturning, which comprises a flange machine, the bottom of the tail end of the flange machine is connected with a positioning plate, and a positioning ring is movably arranged below the positioning plate and positioned at the middle end of a supporting leg of the flange machine. After a flange ring is cut off through a flange machine, the speed reduction motor installed on the front wall of the positioning plate is started, the output end of the speed reduction motor drives the connecting rod to rotate, at the moment, the ram conducts circular motion with the connecting rod as the circle center, and the ram overturns upwards from the lower portion of the through opening and ascends from the lower portion of the supporting rod to pick up the flange ring backwards; the ram continues to turn over, the flange ring is driven to turn over towards the rear supporting rod along with ba
