The invention discloses a device and a method for forming and ring-rolling an outer-diameter roller path of an inner sleeve of a wind-power main shaft forge piece. The device comprises a blank pressing mechanism, a ring-rolling mechanism and a ring piece needing to be machined, wherein the ring piece is sequentially machined through the blank pressing mechanism and the ring-rolling mechanism; andthe ring-rolling mechanism further comprises a centering mechanism and an end face rolling mechanism. The method comprises the following steps of: a, preparing a blank; b, distributing and pressing; c, conducting contour machining; d, heating the blank; and e, conducting forming and ring-rolling. According to the device and method for forming and ring-rolling the outer-diameter roller path of theinner sleeve of the wind-power main shaft forge piece, the continuity of a roller path metal flow line and the structure compactness of the roller path part can be improved, the forge piece outer-diameter contour roller path m
