Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO PARA EL PRENSADO EN SECO DE UN MATERIAL GRANULAR O EN POLVO, A UN DISPOSITIVO ADECUADO PARA UTILIZARLO AL LLEVAR A CABO EL PRENSADO Y A UN APARATO PRENSADOR QUE CONTIENE EL DISPOSITIVO. EL PROCESO DE LA INVENCION COMPRENDE UN PASO DURANTE EL CUAL SE CAMBIA LA PROFUNDIDAD DEL MOLDE Y LA SUPERFICIE SUPERIOR DEL MATERIAL QUE SE ENCUENTRA EN EL MOLDE SE IGUALA SIMULTANEAMENTE. EL DISPOSITIVO CONSTA DE UNA BASE, UN CUERPO PARA SOPORTAR AL MOLDE INFERIOR Y UNA PLURALIDAD DE CILINDROS HIDRAULICOS Y PISTONES SUMINISTRADOS POR UN ELEMENTO DIVISOR DEL FLUJO. LA INVENCION PERMITE OBTENER CUALQUIER PERFIL DE DISTRIBUCION DEL MATERIAL QUE SE ENCUENTRA EN EL MOLDE, EN LA DIRECCION DE LOS ELEMENTOS DE IGUALACION, PARA ASI COMPENSAR CUALQUIER INSUFICIENCIA DE DISTRIBUCION.THE PRESENT INVENTION REFERS TO A PROCESS FOR THE DRY PRESSING OF A GRANULAR OR POWDERED MATERIAL, TO A SUITABLE DEVICE FOR USE IN CONDUCTING THE PRESSING AND TO A PRESSURE DEVICE CONTAINING THE DEVICE. THE PROCESS OF THE INVENTION INCLUDES A STEP DURING WHICH THE DEPTH OF THE MOLD IS CHANGED AND THE UPPER SURFACE OF THE MATERIAL FOUND IN THE MOLD IS SIMULTANEOUSLY EQUAL. THE DEVICE CONSISTS OF A BASE, A BODY TO SUPPORT THE LOWER MOLD AND A PLURALITY OF HYDRAULIC CYLINDERS AND PISTONS SUPPLIED BY A FLOW DIVIDING ELEMENT. THE INVENTION ALLOWS TO OBTAIN ANY PROFILE OF DISTRIBUTION OF THE MATERIAL THAT IS IN THE MOLD, IN THE DIRECTION OF THE ELEMENTS OF EQUALIZATION, IN ORDER TO COMPENSATE ANY INSUFFICIENCY OF DISTRIBUTION.
