STRIKING METHOD AND STRIKING APPARATUS
To provide a striking method and striking apparatus that are simple in equipment and structure and can suppress repulsion of an object, while utilizing instantaneous force of air pressure.SOLUTION: A striking method includes: a step A of supplying compressed air from a compressed air tank AT to a cap-side space A of a cylinder 20 provided in a striking apparatus 10; a step B of feeding hydraulic oil from a high-pressure hydraulic pump HP to a space O of a rod 21 side of the cylinder 20 and lifting a striking portion 50 connected to the rod 21; and a step C of returning hydraulic oil from the space O of the rod 21 side of the cylinder 20 to a hydraulic oil tank OT and dropping the striking portion 50.SELECTED DRAWING: Figure 1
【課題】空気圧の瞬発力を生かしつつ、設備面及び構造面において簡便であり、対象物の反発を抑制可能な打撃方法及び打撃装置を提供する。【解決手段】打撃方法は、圧縮空気タンクＡＴから打撃装置１０に設けられているシリンダ２０のキャップ側空間Ａに圧縮空気を供給するステップＡと、高圧油圧ポンプＨＰからシリンダ２０のロッド２１側空間Ｏに作動油を送油し、ロッド２１に接続された打撃部５０を持ち上げるステップＢと、シリンダ２０のロッド２１側空間Ｏから作動油タンクＯＴに作動油を返油し、打撃部５０を落下させるステップＣと、を備える。【選択図】図１
