摘要
The oleo-pneumatic hammer (7) drives a cutting tool (51) onto a table top (1), and is mounted on a pin-joined (3,5) arm. It comprises a blind vertical cylinder (11) with a piston (29) of a similar flanged (28) form mounted slidably in the open end. The flange (28) comprises the impact plate and together with a slidable inertia mass (24) defines a sealed oil filled chamber (44,45). Ancillary rams enable the block to be lifted relative to the piston (29), its abrupt release then providing the hammer effect. The annular chamber (38) is opened to the atmosphere so that the plate (28) drops onto the tool (51), compressed air now being fed (54) into the chamber (23) to effect the ascent of the mass (24) and create a vacuum in the chamber (45). The chamber is opened to the atmosphere to trigger the abrupt descent of the mass onto the oil in the chamber.
