Patent ID: 7363799

Claim:
A jawset for crimping and punching an associated clamp ring workpiece, the jawset comprising: a pair of spaced apart side plates defining a gap therebetween; a pair of pivot pins extending transversely between the side plates; a pair of jaw arms disposed between said pair of side plates in said gap, the pair of jaw arms having pivot pin openings receiving said pivot pins between said side plates, each jaw arm having inner and outer edges laterally spaced from and extending forwardly, along, and rearwardly of the corresponding pivot pin opening, said inner edges including laterally inwardly directed tooth members and laterally inwardly open opposed jaw recesses forwardly of the pivot pin openings and inwardly facing cam surfaces rearwardly of the openings, the jaw arms during use of the jawset being pivotable about the pivot pins in response to first forces laterally outwardly against the cam surfaces to displace the tooth members laterally inwardly in a first direction to crimp said associated clamp ring workpiece; a punch member extending between said pair of side plates and between said pair of jaw arms, the punch member having a distal end defining an elongate slot and an enlarged proximal end, the punch member during use of the jawset being selectively movable along a longitudinal axis rearwardly in response to a workpiece reactionary force against said distal end during said crimp and forwardly in response to a second force against said enlarged proximal end to slide the distal end forwardly along said inner edges of said pair of jaw arms extending forwardly of the pivot pin openings to punch the associated workpiece in a second direction transverse said first direction; and, a timing disk carried in opposed first and second recesses formed in said inner edges of said pair of jaw arms and extending in said elongate slot defined by said punch member, the timing disk synchronizing relative movement of said pair of jaw arms when a one of said pair of jaw arms is rotated relative to said other of said pair of jaw arms in response to said first forces laterally outwardly against the cam surfaces.
