METHOD FOR CUTTING HELICALLY WOUND WIRE AND APPARATUS FOR PERFORMING THE SAME

摘要

FIELD: production of wire rings. SUBSTANCE: apparatus includes winding unit 3 having inlet opening 2 for receiving wire piece and providing possibility of forming around lengthwise axis helix fed from winding unit in such a way that free end of wire arranged further according to motion direction describes helical trajectory around lengthwise axis along it; cutting unit 4 arranged behind unit 3 and including stationary cutter spaced from unit 3 by interval for laying wire coils at operation; retractable cutter mounted with possibility of motion from cutting position to idle position allowing further motion of free end of wire; support 8 extending in longitudinal direction from limiter zone according to motion direction. Helix formed by winding unit 3 moves forward along lengthwise axis until resting free end of wire limiter. Then cutter moves to cutting position, cuts ring and it is returned to idle position; cut free end of helix moves forward along its helical trajectory causing motion of cut ring on its support for feeding said ring to next processing unit. EFFECT: enhanced efficiency of process, improved design of apparatus. 1 dwg
