ABSTRACT:
In 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 clamping the end of the core rods in a collet-like threaded member such as a slotted set screw threading in a threaded bore in a core rod support member. The core rod support member is preferably in the form of a pair of plates one bolted below the other. The end of each core rod is immobilized in its adjusted position by being disposed in an axial bore in the collet-like threaded member and by being clamped between the sidewalls of a longitudinal slot extending part of the length of the set screw, as a result of the tendency of the slot to close when the set screw is driven through the lower plate with its tapered end engaged with a tapered surface at the end of an aligned bore in the upper plate.
