    摘要： A pressure-receiving face plate 29 is mounted on one end face of a piston 12, and a support member 26 is raised on the end face of the piston 12. Disposed on the support member 26 with an allowance are, from the pressure-receiving faceplate 29 respectively, a disk spring 27, a plate 25, and a plunger 28. A flange 26a prevents these members from slipping off the support member 26. When the piston 12 approaches a stroke end, the plunger 28 is inserted in an oil passage 20b and applies a cushioning effect to the piston 12. In addition, a gap between the pressure-receiving faceplate 29 and the plate 25 brought into contact with a cylinder bottom 17 becomes narrow, and produces a squeeze effect such that oil escapes from the narrow gap. This makes it possible to provide a hydraulic cylinder that produces a sufficient impact force at the stroke end of the piston and also reduces noise emitted by the impact force, without increasing a length of the hydraulic cylinder.

    摘要： A breakthrough buffer for a mechanical press (1) includes at least one buffer body (20) disposed between punch slide (2) and lower press frame (7) to cushion punch plate (3) during breakthrough of punch (4) through a workpiece, a timing regulator (40, 70, 90) connected to each buffer body for regulating timing of buffering during breakthrough, and a control system (60) to provide a command signal to this regulator to minimize noise or vibration occurring during the breakthrough. The control system includes a controller (63) which is responsive to the output of noise sensor (61) or vibration sensor (65) during breakthrough. The buffer body can include fluid driven buffer piston (22) in a buffer cylinder (21), with the buffer piston being associated with a guidepost (5). Alternatively, the buffer body can include piston (82) which contacts the guidepost and which is fluid driven (30, 81) in opposition to spring (83). The timing regulator can include an annular guide (46, 71) which is movable vertically by stepping motor (41) and worm gear drive (42, 44). A locking mechanism (73) can restrain trailing whirl of the guide. Alternatively, the timing regulator can include regulating piston (94) in regulating actuator (93), with fluid pressure on one side being controlled by proportional valve (91) responsive to the command signal, while fluid pressure on the other side is applied to each buffer piston.
