DIE, PUNCH AND CORE ROD ASSEMBLY FOR COMPACTING POWDER MATERIAL

摘要

A die, punch and core rod assembly for a powder compacting press wherein the core rod or rods remain stationary while the punch or punches are reciprocable relative to the die. The invention provides individual longitudinal position adjustment for the core rods by fitting the end of the core rods in a threaded member such as a set screw threading in a bore in the core rod support plate. Alternatively, the invention provides for position adjustment of the core rod support plate by supporting the support plate below the die plate by spacer sleeves having a threaded peripheral portion threading in a bore in the core rod support plate. By combining an adjustable core rod support plate with individually adjustable core rods, the core rods can be adjusted longitudinally relative to each other, and in unison by way of the position adjustment provided for their support plate.
