Armored ring forge piece of corrugated compensator

The utility model provides an armored ring forge piece of a corrugated compensator. The armored ring forge piece comprises an outer ring, a middle ring and an inner ring which are sequentially connected from outside to inside, the two side faces of the middle ring are of a symmetrical structure and comprise a first arc face, a plane and a second arc face which are sequentially connected. The first cambered surface is connected with the outer ring; the second cambered surface is connected with the inner ring. The first cambered surface and the second cambered surface are not only used for improving the structural strength of the armored ring, but also used for preventing the joint of the outer ring and the middle ring and the joint of the inner ring and the middle ring from being broken through arc transition. Due to the fact that the protruding part is still in an arc shape when deforming, the plane is cut according to the deformation range of the protruding part of the ripple compensator, the protruding part
