Abstract

EL DISPOSITIVO EN CUESTION PARA ABOCARDAR EXTREMOS DE TUBOS (9) PRESENTA UNA MATRIZ (1) QUE RODEA EL EXTREMO DEL TUBO, LA CUAL, A SU VEZ, POSEE UNA ABERTURA QUE CORRESPONDE A LA FORMA DEL ABOCARDADO QUE SE PRETENDE EFECTUAR. EN EL INTERIOR DE LA MATRIZ (1) SE ENCUENTRA UN CASQUILLO ENSANCHADOR (4, 14), EL CUAL SE ENSANCHA GRACIAS A UN MANDRIL DE ENSANCHE (3) QUE SE DESPLAZA POR LA ACCION DE UN EMBOLO (15). AL SER ACCIONADO DICHO MANDRIL, QUEDA APRISIONADO EL TUBO (8) ENTRE LA MATRIZ (1) Y EL CASQUILLO DE ENSANCHE (4, 14), Y EL CASQUILLO DE ENSANCHE ESTA PROVISTO DE UN MACHO (5) DESPLAZABLE QUE, AL MOVERSE HACIA LA ABERTURA (10), ABOCARDA EL EXTREMO (9) DEL TUBO.THE DEVICE IN QUESTION TO FOCUS TUBE ENDS (9) PRESENTS A MATRIX (1) THAT SURROUNDS THE END OF THE TUBE, WHICH, IN turn, POSSESSES AN OPENING THAT CORRESPONDS TO THE SHAPE OF THE FOCUS THAT IT IS INTENDED TO CARRY OUT. INSIDE THE MATRIX (1) IS A SPREADING BUSHING (4, 14), WHICH IS SPREADING THROUGH A SPREADING CHUCK (3) THAT MOVES BY THE ACTION OF A PLUNGER (15). WHEN SUCH A CHUCK IS OPERATED, THE TUBE (8) BETWEEN THE MATRIX (1) AND THE ENSANCHE BUSHING (4, 14), AND THE WIDING BUSH IS PROVIDED WITH A MOVABLE MALE (5) WHICH, WHEN MOVING TOWARDS THE OPENING (10), FACES THE END (9) OF THE TUBE.
