Abstract

UN APARATO PARA DOBLAR UN MIEMBRO ALARGADO (12) DE MANERA TRANSVERSAL RESPECTO AL ALMA (46) DE LA MISMA, SIN ALTERAR SUSTANCIALMENTE LA CONFIGURACION DE LA SECCION TRANSVERSAL DE LA MISMA, QUE INCLUYE UNA PIEZA (11) QUE TIENE UNA PLURALIDAD DE ASIENTOS PIVOTALES (17 Y 26) Y UNAS PLACAS FLEXIBLES (39). UNOS MANDRILES FLEXIBLES (63) QUE INCLUYEN UNA PLURALIDAD DE PLACAS PARALELAS (67) SON RECIBIDOS EN DEL MIEMBRO ALARGADO (12) Y, EN COMBINACION CON UNA PLURALIDAD DE ABRAZADERAS (52, 53 Y 54), LA PIEZA (11) Y UNA PLACA DE PRENSAR (33) QUE SOPORTA AL MIEMBRO ALARGADO (12), PREVIENEN QUE LAS FUERZAS DE DOBLADO QUE SE EJERCEN SOBRE EL DISTORSIONEN LA CONFIGURACION DE LA SECCION TRANSVERSAL DEL MIEMBRO ALARGADO (12). LA PIEZA (11) DISTRIBUYE LA FUERZA EJERCIDA, REQUERIDA PARA DOBLAR UNA LONGITUD SELECCIONADA DEL MIEMBRO ALARGADO (12), CON LO QUE SE REDUCE LA FUERZA UNITARIA EJERCIDA EN CUALQUIER PUNTO SELECCIONADO A UN NIVEL QUE NO COMBARA AL MIEMBRO ALARGADO (12).
