Abstract

UN METODO DE PRODUCCION DE COMPONENTES (15) MEDIANTE LA COMPRESION DE UN MATERIAL EN POLVO EN UN MOLDE HUECO (12) INCLUYE EL USO DE UN MANGUITO (16) EN EL MOLDE PARA REDUCIR LA PRESION REQUERIDA PARA QUITAR EL PRODUCTO (15) DEL MOLDE (12) DESPUES DE LA COMPRESION, Y PARA REDUCIR LA DESCOMPOSICION TERMICA EN EL PRODUCTO DESPUES DE LA DEFORMACION RESIDUAL EN LA LIBERACION DEL COMPONENTE. UN MANGUITO ELASTICAMENTE DEFORMABLE (16) QUE TIENE UNA SUPERFICIE INTERNA CILINDRICA Y UNA SUPERFICIE EXTERNA CONICA SE INSERTA EN UNA APERTURA CONICA EN UNA PLACA MOLDE (12) PARA REDUCIR ELASTICAMENTE EL DIAMETRO INTERNO DEL MANGUITO. EL COMPONENTE SE PRODUCE MEDIANTE LA COMPRESION DEL MATERIAL EN POLVO EN EL INTERIOR DEL MANGUITO MEDIANTE TROQUELES SUPERIOR E INFERIORES (13, 14). EL TROQUEL SUPERIOR (13) ES ENTONCES RETIRADO Y EL MANGUITO (16) ES PARCIALMENTE RETIRADO CON EL PRODUCTO (15) DEL MOLDE (12), MEDIANTE UN MOVIMIENTO CONTRA LA DIRECCION CONICA. LA DIMENSION INTERIOR DEL MANGUITO (16) AUMENTA ELASTICAMENTE Y EL PRODUCTO (15) ES ENTONCES RETIRADO DEL MANGUITO LEVANTANDO EL TROQUEL INFERIOR (14).
