Abstract

SE DESCRIBEN UN METODO Y UN APARATO PARA FORMAR UN MUELLE HELICOIDAL CILINDRICO (10). EL APARATO, DE ACUERDO CON EL INVENTO, TIENE UNA CABEZA GIRATORIA (24), Y UN DISPOSITIVO DE FIJACION (48,50) PARA UNIR UN EXTREMO DEL MUELLE HELICOIDAL CON LA CABEZA GIRATORIA, UNA CABEZA DE EMBUTICION (58) QUE SE INSERTA ENTRE LOS ENROLLAMIENTOS ADYACENTES DEL MUELLE CERCA DE DICHO EXTREMO PARA QUE UN TROQUEL DE EMBUTICION SE APOYE CONTRA LA SUPERFICIE INTERIOR DE UN ENROLLAMIENTO, UN PRIMER DISPOSITIVO GIRATORIO PARA HACER GIRAR LA CABEZA EN UN APRIMERA DIRECCION ALREDEDOR DE UN EJE COINCIDENTE CON EL EJE LONGITUDINAL DEL MUELLE HELICOIDAL, Y UN SEGUNDO DISPOSITIVO GIRATORIO PARA HACER GIRAR LA CABEZA DE EMBUTICION EN UNA SEGUNDA DIRECCION, OPUESTA A LA PRIMERA, ALREDEDOR DE UN EJE COINCIDENTE CON EL EJE LONGITUDINAL DEL MUELLE HELICOIDAL. EL METODO, DE ACUERDO CON EL INVENTO, COMPRENDE LAS FASES DE FIJAR UN EXTREMO DEL MUELLE HELICOIDAL A UNA CABEZA GIRATORIA, INSERTAR AL MENOS UN TROQUEL DE EMBUTICION ENTRE LOS ENROLLAMIENTOS ADYACENTES PARA QUE SE APOYE CONTRA LA SUPERFICIE INTERIOR DE UNENROLLAMIENTO, GIRAR LA CABEZA GIRATORIA EN UNA PRIMERA DIRECCION ALREDEDOR DE UN PRIMER EJE COINCIDENTE CON EL EJE LONGITUDINAL DEL MUELLE HELICOIDAL, Y GIRAR AL MENOS EL TROQUEL DE EMBUTICION EN UNA SEGUNDA DIRECCION, OPUESTA A LA PRIMERA, ALREDEDOR DE UN EJE COINCIDENTE CON EL EJE LONGITUDINAL DEL MUELLE HELICOIDAL.
