    • The present invention relates to a hitting body for a hydraulic percussion apparatus and, more specifically, to a hitting body for a hydraulic percussion apparatus which is capable of remarkably reducing production costs by inserting a cylinder liner having a flow path into an inner wall of a body, adjusting a hitting interval and a hitting strength according to properties of a material to be crushed by adjusting a hitting distance of a piston, minimizing the loss of fluid in a duct by forming a cylindrical flow path between the body and the cylinder liner, and minimizing reduction of pressure by employing a circular valve to shorten the flow path, thereby remarkably improving performance. According to the hitting body for a hydraulic percussion apparatus, the production costs and time can be reduced since only the cylinder liner inserted into the body requires to be machined precisely and to be treated by heat, it takes less time for machining since a high-pressure port and a low-pressure port communicate directly with a high-pressure space groove and a low-pressure space groove, the efficiency of the apparatus becomes good due to minimization of the loss of fluid in the duct, the performance is good since the cylindrical valve is formed within the cylinder liner, thus the flow path becomes short and reduction of pressure is less, and the hitting strength can be controlled according to the properties of the material to be crushed since a hitting distance and the hitting interval of the piston can be easily adjusted by opening or closing a short flow path hole using a hole control unit.
    • 本发明涉及一种用于液压冲击装置的打击体,更具体地说,涉及一种用于液压冲击装置的打击体,其能够通过将具有流动路径的气缸套插入到内壁中而显着降低生产成本 通过调节活塞的击球距离,根据待粉碎材料的特性来调节打击间隔和击打强度,通过在主体和气缸套之间形成圆柱形流动路径来最小化管道中流体的损失, 通过采用圆形阀来缩短流路的压力降低,从而显着提高性能。 根据液压冲击装置的打击体,由于仅仅插入到缸体中的气缸套需要精密加工并被加热处理,所以生产成本和时间可以减少,因为高速加工所需的时间更短, 压力端口和低压口与高压空间槽和低压空间槽直接连通,由于管道中的流体损失最小化,设备的效率变好,性能好 圆柱形阀形成在气缸套内,因此流动路径变短并且压力降低较小,并且可以根据待破碎的材料的特性来控制击球强度,因为击球距离和活塞的击球间隔 可以通过使用孔控制单元打开或关闭短流路孔来容易地调节。
