ABSTRACT:
The present invention relates to a ring applying and clinching device for applying successive C-shaped rings to a workpiece. The device comprises a housing structure and a magazine assembly constructed and arranged to support a supply of releasably interconnected C-shaped rings. Each of the rings have opposing leg portions defining an opening therebetween for providing access to an interior of each ring. The magazine assembly comprises structure configured to move the ring supply in a feeding direction such that a lead ring is disposed in a feeding position ready. A pair of opposing jaw members have ring engaging inner surfaces facing generally towards one another. The inner surfaces engage the lead ring in the feeding position. A ring clinching and applying mechanism is constructed and arranged such that manual operation of the actuating mechanism causes the clinching and applying mechanism to (1) move the jaws in a clinching direction such that the inner surfaces thereof engage exterior surfaces of the lead ring in the feeding position thereof so as to grasp the ring without substantially closing the ring opening defined between the opposing leg portions thereof, (2) then move the jaws in an forward direction towards the workpiece without substantial further movement thereof in the clinching direction so as to separate the lead ring from the ring supply and move the lead ring into an applying position wherein the lead ring is disposed forwardly of the housing structure to enable a portion of the workpiece to be received within the lead ring interior through the lead ring opening, and (3) thereafter further move the jaws in the clinching direction such that the inner surfaces further move generally towards one another so as to close the lead ring opening and thereby apply the lead ring in surrounding relation to the workpiece portion received in the interior thereof.
