Abstract

LA INVENCION SE REFIERE A UN SOPORTE HUECO DE CARROCERIA PERFILADO, POR EJEMPLO UN MONTANTE DELANTERO, FABRICADO SEGUN EL PROCEDIMIENTO DE MOLDEO A ALTA PRESION INFERIOR. PARA QUE ESTAS PIEZAS PUEDAN FABRICARSE MAS ECONOMICAMENTE Y CON UN ALTO GRADO DE TRANSFORMACION, DE ACUERDO CON LA INVENCION SE UTILIZA PARA EL SOPORTE HUECO DE CARROCERIA UNA CHAPA DE ACERO LAMINADA EN CALIENTE DE 1,5 A 2 MM DE GROSOR Y DE LA CALIDAD DE ACERO STW24. EL MATERIAL DE PARTIDA PROPUESTO ES MAS ECONOMICO QUE OTROS ACEROS SIMILARES LAMINADOS EN FRIO. ADEMAS, LA CHAPA DE ACERO LAMINADA EN CALIENTE ES MAS DUCTIL, DE CARA AL PROCESO DE MOLDEO A ALTA PRESION INTERIOR, QUE LA CHAPA LAMINADA EN FRIO, Y PUEDE SOMETERSE A UN RECOCIDO INTERMEDIO, SI ES PRECISO, SIN PERDER RESITENCIA.
