Abstract

EN LA FABRICACION DE PASOS EN PIEZAS DE CHAPA POR LA CONFORMACION PASO A PASO MEDIANTE HERRAMIENTAS DE CONFORMACION SE DISMINUYE EL ESPESOR DE PARED DEL PASO RESPECTO AL MATERIAL QUE PASA. ESTO OCURRE ESPECIALMENTE EN EL CASO DE ALTURAS MAYORES DE PASO Y CORTES MAYORES DE CHAPA. EL INVENTO INDICA UN PROCEDIMIENTO CON EL CUAL SE PUEDEN FABRICAR PASOS ALTOS CON UN ESPESOR DE PARED PARECIDO AL ESPESOR DEL MATERIAL INICIAL PARA UNIONES ATORNILLADAS DE ALTA RESISTENCIA DE CORTES DE CHAPA CON GRANDES SUPERFICIES. EN EL PROCEDIMIENTO DEL INVENTO SE PRENSA LA SUPERFICIE DE LA CHAPA DESPUES DE HABER EMPEZADO PARCIALMENTE HACER LAS HUELLAS. ELLO SIGNIFICA QUE LA ZONA DEL BORDE YA NO FIJA Y SE MANTIENE PLANO DURANTE LA CONFORMACION COMO SE HIZO HASTA AHORA, SINO SE INTEGRA EN EL PROCESO DE CONFORMACION Y SE ENDEREZA DESPUES DE NUEVO. EL INVENTO TIENE ESPECIAL IMPORTANCIA PARA LA CONSTRUCCION METALICA ESPECIALMENTE EN LA CONSTRUCCION DE AUTOMOVILES Y APARATOS.
