Abstract
Rolling stand for oblong metal products comprising a plurality of rolling rolls (11) each installed on a respective rotation shaft (12), between at least one rotation shaft (12) and the respective rolling roll (11). A coupling member (15) is provided and is configured to couple the rolling roll (11) and the rotation shaft (12) to each other. The coupling member (15) comprises a tubular body (16) interposed between the rolling roll (11) and the rotation shaft (12) and provided with a chamber (17) in which a deformer element (18) is inserted mobile.
Claims15
A rolling stand for oblong metal products comprising a plurality of rolling rolls each installed on a respective rotation shaft, between at least one rotation shaft and the respective rolling roll there being provided a coupling member configured to couple said rolling roll and said rotation shaft to each other, said coupling member comprising a tubular body interposed between said rolling roll and said rotation shaft, wherein said tubular body is provided with at least one chamber in which at least one deformer element is inserted mobile and is able to be selectively driven to deform said chamber and said tubular body.
A method to install a rolling roll of a rolling stand on a rotation shaft which provides to couple said rolling roll and said rotation shaft by interposing a coupling member, wherein said coupling is achieved by moving at least one deformer element in at least one chamber of a tubular body interposed between said rolling roll and said rotation shaft in order to deform said chamber and said tubular body.
A method to remove a rolling roll of a rolling stand from a rotation shaft, said rolling roll being coupled to said rotation shaft by interposing a coupling member, wherein said removal is achieved by moving at least one deformer element in at least one chamber of a tubular body interposed between said rolling roll and said rotation shaft in order to take said deformer element to a position of non-interference with said chamber.
