Abstract

SE EXPONE UNA PRENSA DE METAL EN POLVO DE ACCION MULTIPLE, PARA REALIZAR PIEZAS COMPACTAS DE ENGRANAJE HELICOIDAL DOBLE EN FORMA TOSCA. LA PRENSA TIENE PUNZONES INFERIORES, INTERIOR Y EXTERIOR, Y UN PUNZON SUPERIOR EXTERIOR. LOS PUNZONES EXTERIORES, SUPERIOR E INFERIOR, TIENEN PERFILES HELICOIDALES EXTERIORES A IZQUIERDAS Y A DERECHAS, ELEGIDOS DE MANERA QUE SE PRODUZCA UN ENGRANAJE HELICOIDAL DESEADO. LOS PUNZONES COOPERAN CON TROQUELES HELICOIDALES A IZQUIERDAS Y A DERECHAS SOPORTADOS POR LA PRENSA ALREDEDOR DE LOS PUNZONES. LAS CARAS HELICOIDALES EXIGEN QUE LOS TROQUELES GIREN EN RELACION CON LOS PUNZONES DURANTE SU FUNCIONAMIENTO. UN MECANISMO DE LEVA Y RODILLO PUEDE ACCIONAR ESTA ROTACION. EL PROCESO DE FORMACION COMPACTA COMIENZA CON UNA POSICION ABIERTA EN LA QUE SE INTRODUCE POLVO EN UNA CAVIDAD LIBRE DEL TROQUEL INFERIOR. LAS PORCIONES SUPERIORES DE LA PRENSA AVANZAN HACIA ABAJO PARA CERRAR LA CAVIDAD. TODAS LAS PARTES DE LA PRENSA, EXCEPTO EL PUNZON INFERIOR INTERIOR, O DE TRANSFERENCIA, SE MUEVEN ENTONCES HACIA ABAJO, A LA MISMA VELOCIDAD, PARA TRANSFERIR EL POLVO A LOS EXTREMOS DEL ESPACIO HUECO. UNA VEZ COMPLETADA LA TRANSFERENCIA, SE PUEDEN DETENER AMBOS PUNZONES INFERIORES, MIENTRAS QUE LOS PUNZONES SUPERIORES CONTINUAN AVANZANDO. LOS TROQUELES AVANZAN A LA MITAD DE LA VELOCIDAD DE LOS PUNZONES SUPERIORES, GIRANDO PARCIALMENTE A MEDIDA QUE LO HACEN. UNA VEZ QUE EL POLVO ALCANZA SU DENSIDAD COMPACTADA, CESA EL MOVIMIENTO DE LOS PUNZONES SUPERIORES E INFERIORES, PERO SUS TROQUELES CONTINUAN GIRANDO, SEPARANDOSE ENTRE ELLOS Y DE LA PIEZA COMPRIMIDA. POR ULTIMO, LA PIEZA ES EXPULSADA Y LA PRENSA RETORNA A SU POSICION INICIAL.
