Abstract
A rolling mill of rotating expander type for tubular bodies, comprising: working rollers (1, 2) arranged inclined with respect to the rolling axis; a tip (3) fitted on a beam (4), so that the tubular body is pushed in rotation between the rollers and the tip, and subjected to deformation in order to increase the perimeter; a tip-stabilizing system placed behind said tip, about the beam, and integrated in the rolling mill.
Claims10
A rolling mill of rotating expander type for tubular bodies, comprising:
- first working rollers provided with rotation axes arranged inclined by a first angle (β) with respect to the rolling axis, and placed at determined heights diametrically opposite to the rolling axis;
- a tip fitted on a beam, said tubular body being pushed so as to rotate between said first rollers and said tip, and subjected to a deformation for increasing the perimeter;
- wherein the rolling mill comprises a tip-stabilizing system placed behind the tip, about the beam, and integrated in the rolling mill.
