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 meets the design requirement, the roller path fatigue resistance is improved, the product quality is improved, meanwhile, the turning allowance is reduced, the machining efficiency is improved, and raw materials are saved.
Description
technical field [0001] The invention relates to the technical field of forging processing, in particular to a device and method for forming and rolling the outer diameter raceway of an inner sleeve of a wind power spindle forging. Background technique [0002] At present, the processing process of the inner sleeve ring of the wind power spindle forging is blanking→heating→blank making→rolling→rough turning→semi-finishing→finishing outer diameter raceway→follow-up processing. Generally, the section of the forging is processed into a rectangular section, and the material other than the raceway is removed. It has the following defects: the streamline continuity of the ring raceway is poor, the structure density of the raceway part and the fatigue resistance of the raceway are low, and at the same time, there is a lot of machining allowance, and more materials need to be turned off, resulting in the loss of raw materials. waste. Contents of the invention [0003] The technic...
