Abstract

SE DESCRIBE UN METODO Y UN APARATO PARA EL DOBLADO DE CHAPA DE METAL PERFILADA, TRANSVERSALMENTE A LAS CRESTAS Y SURCOS LONGITUDINALES DEL PERFIL. ESTO INCLUYE LA SUJECION DE LA CHAPA ENTRE UNA PRIMERA Y UNA SEGUNDA MORDAZAS GIRATORIAS (3,4) SEPARADAS LONGITUDINALMENTE, GIRANDO LA PRIMERA MORDAZA (3) PARA CAUSAR LA DEFORMACION DE LA CHAPA ALREDEDOR DE UNA ESTAMPA (11) MONTADA SOBRE LA PRIMERA MORDAZA, MIENTRAS QUE AL MISMO TIEMPO SE APLICA UNA CARGA DE TRACCION A LA CHAPA MEDIANTE LA SEGUNDA MORDAZA (4). CON PREFERENCIA LA CARGA DE TRACCION SE MANTIENE A UN VALOR CONSTANTE, Y LA SEGUNDA MORDAZA (4) ESTA LIBRE PARA GIRAR ALREDEDOR DE UN EJE BAJO LA INFLUENCIA DE LA CHAPA QUE SE DOBLA.A METHOD AND APPARATUS FOR THE BENDING OF PROFILED METAL SHEET, CROSS-CUTTING TO THE PROFILES AND LONGITUDINAL GROOVES OF THE PROFILE, IS DESCRIBED. THIS INCLUDES THE HOLDING OF THE SHEET BETWEEN A FIRST AND A SECOND ROTATING JAWS (3,4) SEPARATED LONGITUDINALLY, ROTATING THE FIRST JAW (3) TO CAUSE THE DEFORMATION OF THE SHEET AROUND A STAMP (11) MOUNTED ON THE FIRST JAW, WHILE AT THE SAME TIME A TRACTION LOAD IS APPLIED TO THE SHEET METHOD THROUGH THE SECOND CLAMP (4). WITH PREFERENCE THE TRACTION LOAD IS MAINTAINED AT A CONSTANT VALUE, AND THE SECOND CLAMP (4) IS FREE TO ROTATE AROUND A SHAFT UNDER THE INFLUENCE OF THE BENDING SHEET.
