ABSTRACT:
Apparatus for high speed, fully automatic and precise bending of a wire or rod in three dimensions and with the same or different bending radii or bending contours for each bend comprises a passive bending tool (16) having a wire-receiving passage therethrough and a plurality of circumferentially spaced-apart bending surfaces or grooves at its exit end and a bending head (B) having an active bending tool (F) thereon. The passive bending tool (16) is selectively rotatable about a first axis (X) along which the wire extends to align a desired bending surface with a desired bending plane. The bending head (B) is also rotatable about the first axis (X) to position the bending tool (F) at the appropriate side of the wire. The bending tool (F) is rotatable about a second axis (Y), which is perpendicular to the first axis (X), to bend the wire along the selected bending surface.
