Abstract

SE EXPONE UN PROCEDIMIENTO PARA CONFORMAR UNA PARTE METALICA PRENSADA EN EL QUE SE INSERTA UNA PREFORMA (122) EN UN MOLDE METALICO DE PRENSADO. SE LLENA ENTONCES EL MOLDE CON METAL EN POLVO. EL METAL EN POLVO Y LA PREFORMA SE COMPACTAN PARA CREAR UNA PARTE METALICA COMPACTADA, EN DONDE LA PREFORMA DEFINE UN VOLUMEN CONTIGUO PROXIMO A LA PARTE METALICA COMPACTADA. SE EXPULSA LA PARTE METALICA COMPACTADA DEL MOLDE, Y SE SINTERIZA PARA CREAR UNA PARTE METALICA SINTERIZADA. EN LA ETAPA DE SINTERIZACION, SE EXTRAE LA PREFORMA DE TAL MANERA QUE EL VOLUMEN CONTIGUO SE CONVIERTA EN UNA ZONA DE RECHUPE. SE PUEDE CONFORMAR LA PREFORMA DE COBRE PARA QUE, JUSTO DESPUES DE LA SINTERIZACION, LA PREFORMA SE EXTRAIGA DE LA PARTE METALICA SINTERIZADA POR INFILTRACION. ALTERNATIVAMENTE, SE PUEDE CONFORMAR LA PREFORMA DE ZINC PARA QUE, JUSTO DESPUES DE LA SINTERIZACION, LA PREFORMA SE VAPORICE Y SE EXTRAIGA ASI DE LA PARTE METALICA SINTERIZADA. LA ZONA DE RECHUPE CREADA POR LA EXTRACCION DE LA PREFORMA, PUEDESER UN REBAJE, UN AHUSAMIENTO, UNA ACANALADURA ANULAR, UNA ROSCA O UNA CAVIDAD INTERNA. DE ESTA MANERA, LA PRESENTE INVENCION ELIMINA LA NECESIDAD DE MECANIZAR TALES SUPERFICIES, COMO HA SIDO NECESARIO USANDO METODOS ANTERIORES DE COMPACTACION.
