Abstract

Espansore meccanico per tubi per espandere, simultaneamente, più tubi ad U, in modo tale da stabilire una relazione di interbloccaggio con più alette, includente un telaio con un mezzo atto a supportare le porzioni piegate dei tubi. Inoltre, viene prevista, sul telaio, una struttura di supporto per impegnare e supportare una prima aletta terminale. Viene pure impiegata una piastra di pressione supportante una pluralità di barre di espansione, ognuna allineata con i tubi ad U. Le barre di espansione si estendono attraverso le corrispondenti aperture di guida. Viene pure prevista una struttura per impegnare un secondo foglio terminale. Vengono pure impiegati dispositivi separati di comando per effettuare un movimento selettivo e coordinato della piastra di pressione, delle piastre di estrazione e della struttura di supporto. Viene ottenuto un allargamento del diametro delle porzioni a ramo diritte per effettuare un fissaggio di ognuna delle alette ai tubi ad U e ai tubi diritti.
