RADIAL-AXIAL RING ROLLING MILL FOR RING ROLLING Russian patent published in 2021 - IPC B21H1/06 B21B13/08 B21B31/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a radial-axial rolling mill for rolling a ring. The mill has an axial rolling device and a radial rolling device. The radial rolling device has a main roll and a roller mandrel, between which the possibility of forming the specified ring is provided. The roller mandrel in its upper region is held in the head of the mandrel support, which is installed with the possibility of horizontal permutation in the first linear permutation device so that the roller mandrel is movable perpendicular to its longitudinal extension in the direction of the main roll and opposite to it. The first linear permutation device together with the mandrel support head and the roller mandrel are made with the possibility of vertical permutation in the form of a single module by means of a second linear permutation device so that it is possible to extract the roller mandrel from the inner space of the ring and insert it into it.

EFFECT: geometric relationship is adjusted to the size of the ring to be rolled.
