SPRING MANUFACTURING MACHINE

PROBLEM TO BE SOLVED: To provide a spring manufacturing machine which can keep respective travel distances of plural processing tools at a prescribed ratio.SOLUTION: A spring manufacturing machine is equipped with a wire feed roller for feeding a wire; plural tool holders for holding a processing tool which processes the wire fed from the wire feed roller into a spring; and a mover mechanism for moving the plural tool holders. The spring manufacturing machine is characterized in that the mover mechanism has a support plate for supporting a power source, a main slider which is slidably provided on the support plate and is linearly moved by a power from the power source, plural follower sliders which are connected to the main slider and hold the plural tool holders, and plural connection parts which connect the main slider and each of the plural follower sliders to each other, and each of the plural connection parts is so located as to cross a movement locus of the main slider at a prescribed angle.SELECTED DRAWING: Figure 3 【課題】複数の加工ツールそれぞれの移動距離を所定の比率に保つことができるばね製造機を提供する。【解決手段】線材を送出する線材送りローラと、該線材送りローラから送出された線材をばねに加工する加工ツールを保持する複数のツール保持具と、該複数のツール保持具を移動させるための移動機構とを備えるばね製造機において、前記移動機構は、動力源を支持する支持板と、該支持板に摺動可能に設けられており、前記動力源の動力によって直線的に移動する主動スライダ及び該主動スライダに連結され、前記複数のツール保持具を保持した複数の従動スライダと、前記主動スライダ及び複数の従動スライダそれぞれを連結する複数の連結部とを有し、前記複数の連結部それぞれは、前記主動スライダの移動軌跡に対して所定の角度で交差するように配置されていることを特徴とするばね製造機。【選択図】図３
