MOVABLE BLADE STRUCTURE AND CUTTING DEVICE USING THE SAME

To provide a movable blade structure which can be made a compact and which can reduce production cost, and a cutting device using the same.SOLUTION: A cutting device 10 is configured so that, a stationary blade 180 and a movable blade 110 provided on a movable blade structure 90 cut a plate-shaped member W. The movable blade structure 90 comprises at least two movable blades 110 in a manner in which, heights of crown parts 112 of the movable blades are different each other. The cutting device further comprises an air cylinder 80 as a reciprocation device for reciprocating the movable blade structure 90 between an initial position and a cutting completion position for completing cutting of the plate-shaped member, along a thickness direction of the plate-shaped member W. The movable blade structure 90 is arranged on the air cylinder 80.SELECTED DRAWING: Figure 5 【課題】小型化して製造コストを低減させることができる可動刃構造体及びそれを用いた切断装置を提供する。【解決手段】切断装置１０を、固定刃１８０と可動刃構造体９０に配された可動刃１１０とで板状部材Ｗを切断する構成とする。可動刃構造体９０には、少なくとも二つの可動刃１１０が、それぞれの頂部１１２の高さを異ならせて配設される。可動刃構造体９０を、初期位置と板状部材の切断を完了させる切断完了位置との間で、板状部材Ｗの厚さ方向に沿って往復移動させる往復移動装置としてのエアシリンダ８０を備える。エアシリンダ８０に可動刃構造体９０が配設されている。【選択図】図５
