<p>A wire spring forming device whereby it is possible to increase the number of slide plates without requiring an increase in the number of servo-motors serving as drive sources. The wire spring forming device comprises a rotating table (10) disposed around a quill (6) for guiding a wire material (41), slide units (15) which are radially disposed on the table (10) at approximately equidistant positions in the circumferential direction and which are capable of moving forward or backward, and slide plates (33) which are disposed on the outside of the table (10) at multiple positions radially corresponding to slide units (16) and which are capable of being driven forward and backward in the radial direction by the servo-motors (M3). The forward movement of a desired slide plate (33) presses and moves forward the corresponding slide unit (16) and makes tools (T) attached to the slide unit (16) abut against the wire material (41) fed from the quill (6), thereby forming the wire spring. The slide plates (33) are annularly disposed in proximity to each other, and a pair of slide plates (33, 33) are selectively moved forward by driving one servo-motor (M3) installed in such a manner as to correspond to each pair of adjacent slide plates (33, 33).</p> |
