Patent attributes
A clinching machine and method for using a clinching machine are provided. In another aspect, a hand-held clinching machine and method employ a movable jaw, a cam wedge, and a rocker arm to control opening and closing movement of the clinching jaw. Another aspect of a clinching machine and method includes a movable clinching jaw, a fluid activated piston, a manually actuated switch which causes fluid actuated rotation of a lever, a manually actuated trigger to fluidically advance a piston and a block attached to a forward end of a piston rod, and an abutting stop surface movable with the movable jaw, where the stop surface abuts against the lever in an operating condition to limit opening rotation of the movable jaw to an intermediate position between a fully open position and a fully closed and clinching position.
