ABSTRACT:
A tool assembly for shaping workpieces, which comprises a reciprocable punch having a working end engageable with a die to shape a workpiece therebetween. The punch is mounted at its driven end on a reciprocable punch actuator and extends through a floating punch guide having an end adjacent the die which is axially and circumferentially engaged with a recess in the die to align the die and punch axes during the workpiece shaping operation. A workpiece feed tube opens laterally into the punch guide, and the punch guide is reciprocable in response to reciprocation of the punch to open and close the discharge end of the feed tube so as to assure singular feeding of workpieces to the die cavity.
