Spring forming device and forming method therefor

A spring forming device comprising:

• a wire supplying mechanism for supplying a steel wire using a plurality of feeding rollers,
• a heating mechanism for heating the steel wire,
• a coiling mechanism for forming in a coiled state the heated steel wire, and
• a cutting mechanism for cutting the steel wire coiled at a given number of turns off the steel wire remained backward,
• wherein the coiling mechanism comprises:
• a wire guide for inducing the steel wire supplied by the feeding rollers to an appropriate position in a processing portion,
• a coiling tool for processing the steel wire supplied through the wire guide to a coiled shape, and
• a pitching tool for forming pitches on the steel wire in a coiled shape, the cutting mechanism comprises:
• a cutting blade for cutting the steel wire coiled at a given number of turns off the steel wire remained backward, and
• a receiving blade for supporting the steel wire arranged opposite to the cutting blade,
• a region for heating the steel wire in the heating mechanism is arranged between the feeding rollers and the wire guide, and
• the cutting blade follows tracks having a speed Va that moves to the receiving blade and a speed Vc that moves in an axial direction of the coiled steel wire, in cutting of the steel wire.
