ABSTRACT:
A clamping jaw for gripping wire stock used in nail production machines includes a quick change system that allows efficient replacement of a removable tool insert. The clamping jaw includes a main body that is partially split so as to define a gap between first and second opposing clamping fingers having a recess portion there between for receiving and retaining the insert. The main body includes a top surface, a bottom surface, a central bore that extends between the first and second surfaces, and a countersunk cavity formed in the bottom surface. A tapered projection formed from the first and second clamping fingers extends into the countersunk cavity. A clamping member, having a tapered recess for receiving the projection, is positioned in the countersunk cavity. A fastener is tightened to draw the clamping member onto the projection to close the clamping fingers in order to grip the insert.
