Abstract
METODO PARA DOBLAR MATERIAL DE CHAPA. CONSISTE EN SITUAR EL MATERIAL DE CHAPA (A) ENTRE UN ELEMENTO DE PUNZON MACHO (15) Y UN ELEMENTO DE MOLDES HEMBRA (25) QUE TIENE UN CONTRAPUNZON MOVIL (26) SITUADO EN EL, PARA OPONERSE DE MANERA CONTROLABLE A LA FUERZA DEL PUNZON (15). AL PRENSAR UN ELEMENTO CONTRA OTRO, EL MATERIAL (A) SE VA DOBLANDO EN DIFERENTES ETAPAS CON EL FIN DE PERMITIR RECUPERACIONES ELASTICAS SUCESIVAS. COMO ALTERNATIVA, ESTA INVENCION ADMITE LA REALIZACION DEL DOBLADO EN UNA ETAPA UNICA.
