ABSTRACT:
A wire straightening machine comprising a motor-driven, rotatable hollow shaft with at least three serially arranged dies mounted thereon, having central apertures through which the wire is passed. The outer end dies are fixed with respect to the shaft, with their apertures located on the axis of rotation. The middle die is movable radially between a first position in which its aperture is coaxial with the axis of rotation, and a second position in which the aperture is eccentrically offset with respect to the axis of rotation. The middle die is carried by a block that slides through a transverse slot in the shaft, and the ends of the block have inclined parallel faces that engage inclined guideways on a slotted link, which slides axially along the shaft. An actuating device is connected to the slotted link so that the latter can be shifted axially to move the aperture of the middle die from one position to the other.
