Abstract
A stretch reducer and/or calibrating rolling mill for rod-shaped bodies, in particular tubular bodies, in particular hollow bodies, said rolling mill comprising a plurality of rolling stands each comprising a plurality of rolling rollers mutually arranged so as to define a passage for said rod-shaped bodies, wherein said rolling stands are arranged in sequence along a rolling direction so that the respective passages are substantially aligned to define a rolling path substantially parallel to said rolling direction, wherein each of at least two of said rolling stands comprises three rolling rollers.
Claims14
A calibrating roll mill for rod-shaped bodies comprising a plurality of rolling stands, wherein each of said plurality of rolling stands comprises a plurality of rolling rollers mutually arranged so as to define a respective passage for said rod-shaped bodies, wherein said plurality of rolling stands are arranged in sequence along a rolling direction so that said respective passages are aligned to define a rolling path parallel to said rolling direction, wherein at least two rolling stands of said plurality of rolling stands each comprise said plurality of rolling rollers consisting of three rolling rollers, wherein each rolling stand of said at least two rolling stands is individually constrained within said calibrating rolling mill;
- wherein each rolling stand of said at least two rolling stands is translationally positionable between a first position, in which said respective passages are substantially aligned to define said rolling path, and a second position;
- and
- wherein, in said first position, each rolling stand of said at least two rolling stands rests on a respective positioning guide shaped so that a translation from said second position to said first position on said respective positioning guide results in an at least vertical positioning of said rolling stand;
- and
- wherein for each rolling stand of said at least two rolling stands, said calibrating rolling mill comprises at least one fixed transversal positioning abutment for positioning said rolling stand transversely to said rolling direction and parallel to a translation direction of said rolling stand from said second position to said first position.
A stretch reducer rolling mill for rod-shaped bodies comprising a plurality of rolling stands, wherein each of said plurality of rolling stands comprises a plurality of rolling rollers mutually arranged so as to define a respective passage for said rod-shaped bodies, wherein said plurality of rolling stands are arranged in sequence along a rolling direction so that said respective passages are aligned to define a rolling path parallel to said rolling direction, wherein at least two rolling stands of said plurality of rolling stands each comprise three rolling rollers, wherein each rolling stand of said at least two rolling stands is individually constrained within said stretch reducer rolling mill;
- wherein each rolling stand of said at least two rolling stands is translationally positionable between a first position, in which said respective passages are substantially aligned to define said rolling path, and a second position;
- wherein, in said first position, each rolling stand of said at least two rolling stands rests on a respective positioning guide shaped so that a translation from said second position to said first position on said respective positioning guide results in an at least vertical positioning of said rolling stand;
- and
- wherein for each rolling stand of said at least two rolling stands, said stretch reducer rolling mill comprises at least one fixed transversal positioning abutment for positioning said rolling stand transversely to said rolling direction and parallel to a translation direction of said rolling stand from said second position to said first position.
