Abstract
A method is provided for bending a difficult-to-work metallic wire into a complicated profile. A predetermined length of the difficult-to-work metallic wire is prepared. Part of a portion thereof is held by a conductive clamping device. A first conductive pressure member is brought into contact with a first bending work position of the workpiece, while applying a predetermined pressing force thereto, electric power is supplied between the first member and the clamping device via the wire. Thereby, the wire is bent by a predetermined amount, which part of the wire thus bent by the predetermined amount is located on a conductive rod having a circular cross-section. A second conductive pressure member is brought into contact with a second bending work position of the wire, while applying a constant pressing force to the second member, electric power is supplied between the second member and the conductive rod via the wire. In this state, the relative displacement is caused between the second member and the conductive rod in the bending direction.
