Abstract
UNA BARRA PARACHOQUES (1) PARA VEHICULOS SE FORMA A PARTIR DE ACERO EN LAMINAS ENROLLADAS (5) CON UN PERFIL TUBULAR CERRADO CON UNA SOLDADURA LONGITUDINAL (13) ENTRE EXTREMOS SALIENTES DE LA LAMINA Y SE DISEÑA PARA TENER UNA ALTA RESISTENCIA A LOS GOLPES, ALTA PROPORCION ENTRE RESISTENCIA Y PESO, Y UN BAJO COSTE DE FABRICACION. LA BARRA SE EXTIENDE PREFERENTEMENTE A LO LARGO DE SU EJE LONGITUDINAL PARA FORMAR UNA CURVATURA DE ACUERDO CON LOS MODERNOS DISEÑOS DE AUTOMOVILES. EL APARATO PARA FABRICAR LA BARRA INCLUYE UNOS PRIMEROS RODILLOS (23-29) QUE FORMAN UNA MUESCA EN EL TUBO Y SEGUNDOS RODILLOS (29A, 29B) QUE SE ACOPLAN A LA MUESCA PARA HACER AVANZAR EL TUBO EN EL ELEMENTO DE FORMACION DE LA EXTENSION (33), EL ELEMENTO DE FORMACION DE LA EXTENSION INCLUYE UN CONJUNTO DE EJES CORTOS (34A, 34B) LLEVADOS POR ELEMENTOS DE SOPORTE (41, 42) SOPORTADOS POR UNA ESTRUCTURA DE ANCLAJE (43).
