Abstract
To easily adjust and change a locus of a leading end (an endless locus) of a cutter, a wire rod cutting apparatus of spring manufacturing machine has structure so that a slide may vertically slide via a connection rod by rotating a rotation shaft, and a cutter mounting oscillating arm can oscillate laterally via a sliding element by oscillating the connection rod, so that the locus thereof in the oscillating arm can be set to a predetermined shape which is endless in a front view and different between an outward and a homeward routes, by sliding the slide and oscillating the oscillating arm by actuation of the actuating apparatus and that a lateral oscillating amount of the oscillating arm can be changed by changing the position of the sliding element, to change the locus of the cutter leading end.
