Wire spring forming apparatus

A wire spring forming apparatus in which a plurality of forming tools are radially arranged around the axis of a quill guiding a wire which is held between pressure feed rollers and is pressure fed on the basis of a rotation of the pressure feed rollers so as to be movable forward and backward in perpendicular to or substantially in perpendicular to the axis of the quill, the pressure feed rollers can revolve around the axis of the wire in the state of holding the wire to be pressure fed between the pressure feed rollers,

• wherein one of the pressure feed rollers and a power transmitting means for transmitting a drive force to the pressure feed roller are mounted to a main portion main frame of a revolving means supported to a main body frame rotatably or position adjusting arms in both sides respectively swingably supported to the main portion main frame, and another of the pressure feed rollers is mounted to supporting arms in both sides swingably attached to a fulcrum shaft rotatably supported to the main portion main frame in perpendicular to the wire pressure feeding direction, in the state that gears for driving the pressure feed rollers arranged neighbouring the respective pressure feed rollers are engaged with each other, respectively, and
• the pressure feed rollers are positioned at the middle or a substantially middle of spindles having both ends supported or pivoted to the main portion main frame or the position adjusting arms and the supporting arms in both sides respectively swingably supported to the main portion main frame, and a point of application of pressure with respect to the pressure feed roller in the side of the supporting arm is positioned immediately above the pressure feed rollers.
