Spring manufacturing apparatus

A spring manufacturing apparatus for forming a spring from a wire fed from an end of a wire guide, and forcibly bending or coiling the wire with the use of tools which are pointed against the wire for bending and coiling the wire, and are arranged slidably in a radial pattern toward a spring-forming space near the end of the wire guide said wire guide having an internal portion with internal walls, said wire guide having a wire feedout hole within internal walls for feeding the wire to the spring-forming space,

• the apparatus comprising:
• rotating means, rotatably provided in a central area of a main body of the apparatus where sliding locus of the tools intersects, for rotating the wire guide around the wire feedout hole while supporting the wire guide;
• first driving means for transmitting rotation force to said rotating means;
• wire-feeding means, provided in an upstream side of a wire-feeding path along a wire direction of said rotating means, for feeding the wire to the spring-forming space through the wire feedout hole by rotating the wire while gripping the wire;
• second driving means for driving said wire-feeding means;
• wire-gripping means, provided in said internal portion of said wire guide, for gripping the wire between the internal walls of said wire feedout hole;
• third driving means for driving said wire-griping means to grip the wire;
• and
• controlling means for controlling said first, second and third driving means at a predetermined timing, and rotating said rotating means while said wire-feeding means and said wire-gripping means grip the wire, so that the wire positioned between said wire-feeding means and wire-gripping means is temporarily twisted and a direction of the wire fed from the wire feedout hole is changed.
