Patent attributes
A jawset for crimping and punching an associated clamping workpiece has a pair of spaced apart side plates, a pair of pivot pins holding a pair of jawarms between the side plates, tooth members formed on the jawarms to crimp an associated clamp ring workpiece in a first direction, and a punch member slidable in the jawset relative to the jawarms to punch the associated workpiece in a second direction transverse the first direction. In one form, a timing disk is provided extending between the jawarms and through the slidable punch member. A biasing member is provided for urging the jawarms in an opening direction opposite the crimping direction. A workpiece alignment area is defined by a region of the spaced apart side plates for enabling relative alignment between the jawset and the associated workpiece. In a further embodiment, a pair of auxiliary side plates are carried adjacent ruggedized side plates for enabling an alignment area without adding undue weight or cost to the jawset. In a further embodiment, the jawarms are provided with stop members forward of the pivot pins including inwardly directed abutment surfaces for controlling a closure amount of the tooth members during the crimping operation. Still further, the punch member selectively provides both a hard stop during the crimping operation as well as a movable punch during the pressing operation based on a relative size of the workpiece.
