Abstract
A lower punch assembly for use in a rotary table, powdered metal compacting press includes a punch shank defining a cam follower, a core rod disposed within the shank, and a mounting assembly for mounting the shank to the press and permitting the shank to rotate with respect to a vertical axis of the shank. In one embodiment, the mounting assembly includes a bearing member from which a plurality of hanger rods extend. The shank is slidably mounted on the hanger rods. The core rod is engaged by a spring and is connected to the shank so that it will withdraw or extend during an ejection stroke to reduce ejection loading.
