ABSTRACT:
An apparatus for making a copper-aluminum transition joint characterized by utilizing a combination die and metal shears mounted between a pair of abrading brushes and wire feeding devices that are operable, respectively, to feed a copper wire and an aluminum wire into overlapping relationship between relatively movable die surfaces, after the wires have been abraded to remove oxidized portions thereof and to remove contaminants from the wires. The respective wire feeding devices cooperate with limit stops formed in the relatively movable dies to assure rapid, accurate positioning of the two wires over a punch in a double-action die that operates to form a cold welded transition joint between the wires when the dies are closed. The wire feed devices also selectively retract the sheared ends of the wires from the transition joint to facilitate rapid ejection of the joint from the die. A reciprocally operable pusher member is mounted adjacent the die punch to eject transition joints from the die in a direction transverse to the paths of movement of the copper and aluminum wires between the dies.
