Wire bending machine
摘要:
A machine for bending wire into a ring having a plurality of circumferentially spaced and radially outwardly projecting loops. A loop is formed by the cooperation of a pair of first mandrels longitudinally spaced apart on one side of a wire segment and a second mandrel normally positioned on the other side of the wire segment and moved generally transversely across the longitude of the wire segment along a path between the first mandrels while essentially simultaneously the first mandrels are moved generally longitudinally toward each other. Pairs of third and fourth mandrels disposed on opposite sides of the wire form bends in the wire to provide a plurality of rectilinear portions interconnecting adjacent loops to form a ring-like configuration.
