Abstract

PROCEDIMIENTO Y APARATO PARA LA VIBRACION Y LA COMPACTACION DE ARENA, PARA MOLDES DE FUNDICION. UNA UNIDAD DE COMPACTACION DE ARENA (12) PARA MOLDES DE FUNDICION QUE POSEE UN BASTIDOR (14) MONTADO ELASTICAMENTE EN UN SOPORTE RIGIDO (10); EL BASTIDOR SOSTIENE RIGIDAMENTE UNA CAJA DE MOLDEO (24) Y TIENE POR LO MENOS UNA PAREJA DE MOTORES SINCRONIZADOS (A) CON ROTORES EXCENTRICOS ACOPLADOS CON EL BASTIDOR PARA EFECTUAR UN MOVIMIENTO VIBRATORIO CONJUNTAMENTE CON EL MISMO. LAS PAREJAS DE MOTORES ESTAN SINCRONIZADAS PARA ROTACION EN SENTIDO CONTRARIO; CADA PAREJADA PRODUCE UN VECTOR DE FUERZA NETA PERPENDICULAR A UNA LINEA QUE UNE ENTRE SI SUS MOTORES. EXISTEN TRES PAREJAS DE MOTORES (A, B, C) ACTUANDO SEGUN TRES EJES DIFERENTES, PERPENDICULARES ENTRE SI CONTROLADAS POR MEDIO DE UN PROGRAMA QUE PERMITE ESPECIFICAR SECUENCIALMENTE -SOBRE UNA AMPLIA GAMA DE VALORES- LA ACELERACION DEL VECTOR NETO Y EL TIEMPO DE DURACION DE LA MISMA. LOS MOTORES SON MANTENIDOS DURANTE EL INTERCAMBIO DE LAS CAJAS DEMOLDEO EN UNA RELACION SINCRONIZADA DE FASES, COMENZANDO LOS VECTORES DE COMPACTACION A PARTIR DE UNA CONDICION INICIAL DE MARCHA EN VACIO.
