A three-dimensionally shaped round metallic wire having a cross-section non-circular portion in a predetermined portion without performing additional processing and having specified dimensional accuracy and accuracy of form. In an intermediate step in which the round metallic wire is processed in a predetermined three-dimensional shape, a cross-section non-circular portion forming machine 20 which forms the cross-section non-circular portion having a non-circular cross-sectional shape in at least one position is included. At the time of bending, the cross-section non-circular portion is held by a wire holding portion of a bending machine 30, and the bending is performed in the predetermined three-dimensional shape. Holding the cross-section non-circular portion causes relative rotation between the cross-section non-circular portion and the wire holding portion to be suppressed as compared with a case of the cross-section circular shape. Accordingly, bending accuracy in the three-dimensional shape for the round metallic wire is improved.

To simplify a commissioning and parameter change in a 3D bending process of wires, a 3D bending device and a 3D bending method for bending a wire are provided. The wire is held by a first leg and a second leg and the legs are moved, via a first to third relative movement device, in a first to third relative movement with a first to third movement axis in order to change, in an adjustable manner independently of one another, torsion angles of the first and second legs and a distance between the central axes of the legs.

A hairpin type of stator coil forming apparatus includes a first forming machine configured to form a vertex in a material coil so that a central portion of the material coil protrudes upward, and to form inclined portions inclined to both sides of the vertex, a second forming machine configured to receive the material coil bent-formed by the first forming machine and to form a front/rear bent portion in the material coil by bending one inclined portion and a portion of the other inclined portion based on the vertex, and a third forming machine configured to receive the material coil bent-formed by the second forming machine and to roundly form the inclined portions in front and rear directions.
