Straightening device for air valve steel machining

The utility model discloses a straightening device for air valve steel machining, which comprises an adjusting device for supporting, the upper end face of the adjusting device is in threaded sliding connection with a supporting sliding seat, one side of the upper end face of the supporting sliding seat is symmetrically provided with guide sliding grooves, and the other side of the upper end face of the supporting sliding seat is symmetrically provided with guide threaded holes. Upper straightening rollers are evenly and rotationally clamped to the inner end face of the supporting sliding base at equal intervals. By arranging the adjusting device, when air valve steel of different models is adjusted and controlled, a user can synchronously drive the two sets of connecting lead screws through the servo motor, then the distance between the supporting sliding base and the adjusting device is rapidly adjusted, meanwhile, the straightening force of the upper straightening roller and the straightening force of the
