Abstract

LA INVENCION SE REFIERE A UNA PARTE (7) PRENSADA DE POLVO METALICO, EN PARTICULAR PARTE (7) SINTERIZADA CON AL MENOS UNA ENTRADA (3) DE MOLDEO QUE SE ENCUENTRA DE FORMA TRANSVERSAL CON RESPECTO A LA DIRECCION DE PRENSADO, QUE MEDIANTE LA CONFORMACION DE UNA PARTE (2) DE PRENSADO DE PRODUCTO PREVIO DE UNA SOLA PIEZA SE CONFORMA PARA LA OBTENCION DE UNA PARTE (7) FABRICADA A TRAVES DE UN PROCESO DE PRENSADO ADICIONAL. LA PARTE (2) DE PRENSADO DE PRODUCTO PREVIO, QUE PUEDE MOSTRAR UNA DISPOSICION DE ESPALDILLA QUE SOBRESALE EN LA ENTRADA (3) DE MOLDEADO, DISPONE EN LA CARA DIRIGIDA A ESTA ENTRADA (3) DE MOLDEO UNA OTRA DISPOSICION (5) DE ESPALDILLA QUE SOBRESALE Y LIMITA DE TAL MODO, QUE UNA DE LAS ESPALDILLAS (5) SE EJECUTA EN FORMA DE RECIPIENTE (8) DE RESERVA DE MATERIAL EQUIVALENTE A TRAVES DE UN PROCESO DE PRENSADO ADICIONAL, QUE DISPONE DE UNA MATRIZ (14) QUE MUESTRA LA FORMA CORRESPONDIENTE, SIENDO APOYADA ESTA FORMA EN LA ESPALDILLA (5) Y PRESIONADA. LA MATRIZ (14) SE COMPONE AL MENOSDE DOS SEGMENTOS (15) MOVILES DE FORMA TRANSVERSAL CON RESPECTO A LA DIRECCION DE PRENSADO, RESULTANDO PRENSADOS UNO CON OTRO EN EL PROCESO DE PRENSADO POR MEDIO DE UN DISPOSITIVO DE SUJECION Y SIENDO MOVIDOS UNO CON OTRO SEGUN EL PROCESO DE PRENSADO PARA EL DESMOLDEADO DE LA PIEZA (7) DE PRENSADO POR EJEMPLO POR MEDIO DE FUERZA ELASTICA.
