Abstract

L'INVENTION CONCERNE UNE CINTREUSE POUR TUBES SERVANT A FORMER DES COUDES. AU BATI 27 DE LA CINTREUSE SONT FIXES, DE MANIERE DETACHABLE, UN MANDRIN COURBE 1 ALLANT EN S'EPAISSISSANT ET UN BRAS DE MAINTIEN 2. LE BRAS DE MAINTIEN 2 S'ETEND SELON UN ARC DE CERCLE DE PLUS DE 110, EST RELIE DE MANIERE DETACHABLE A L'EXTREMITE DU MANDRIN 1 PAR L'INTERMEDIAIRE D'UN ENGRENEMENT D'ACCROCHAGE 7 ET EST MAINTENU DE FACON MOBILE PAR RAPPORT AU BATI 27 POUR LIBERER L'ENGRENEMENT D'ACCROCHAGE 7. CETTE CINTREUSE PERMET DE FABRIQUER DES COUDES COUVRANT UN DOMAINE DE PLUS DE 180.THE INVENTION CONCERNS A BENDER FOR TUBES FOR FORMING ELBOWS. TO FRAME 27 OF THE BENDER ARE FIXED, IN A DETACHABLE MANNER, A CURVED CHUCK 1 GOING THICKENING AND A HOLDING ARM 2. THE HOLDING ARM 2 EXTENDS ACCORDING TO A CIRCLE ARC OF MORE THAN 110, IS CONNECTED BY DETACHABLE WAY AT THE END OF CHUCK 1 BY INTERMEDIATE OF A HITCH GEAR 7 AND IS MAINTAINED MOVABLE IN RELATION TO THE BUILD 27 TO RELEASE THE HITCH GEAR 7. THIS BENDER ALLOWS TO MAKE COVER ELBOWS A DOMAIN OF OVER 180.
