Abstract

Procedimento per conformare secondo una sezione trasversale circolare l'estremità di un tubo (2) a sezione trasversale oblunga, in cui la conformazione avviene in un'unica fase di compressione radiale dall'esterno. Il tubo (2) viene disposto con il proprio asse minore in corrispondenza di due superfici di contrasto fisse (12, 14), aventi un profilo circolare con raggio di curvatura (R) circa pari al raggio della sezione circolare del tubo che si desidera ottenere. Quindi di esercita una compressione radiale lungo l'asse maggiore della sezione oblunga del tubo indeformato mediante una coppia di superfici di conformazione (22, 24), aventi un'estensione angolare complementare a quella delle superfici di contrasto fisse (12, 14).(fig. 4).
