Radial/axial ring rolling mill for rolling a ring
A radial/axial ring rolling mill for rolling a ring has an axial rolling device and a radial rolling device. The radial rolling device includes a main roller and a roller mandrel, between which the ring can be shaped. The roller mandrel is retained in the upper region thereof on a mandrel bearing head supported in a first linear adjustment device to be able to be horizontally adjusted in such that the roller mandrel can be moved perpendicularly to the longitudinal extent thereof in the direction towards the main roller and in the opposite direction thereto. The first linear adjustment device together with the mandrel bearing head and the roller mandrel is able to be adjusted as a unit by a second linear adjustment device in a vertical manner so that the roller mandrel can be pulled out of the inner space of the ring and introduced therein.
1. Radial/axial ring rolling mill for rolling a ring comprising an axial rolling device and a radial rolling device, wherein the radial rolling device has a main roller and a roller mandrel, between which the ring can be shaped, wherein the roller mandrel is retained in an upper region of the roller mandrel on a mandrel bearing head which is supported in a first linear adjustment device so as to be able to be horizontally adjusted in such a manner that the roller mandrel can be moved perpendicularly to a longitudinal extent of the roller mandrel in a direction towards the main roller and in an opposite direction away from the main roller, wherein the first linear adjustment device together with the mandrel bearing head and the roller mandrel can be translated vertically as a unit by a second linear adjustment device so that the roller mandrel can be pulled out of an inner space of the ring and introduced therein.
