摘要： When a start switch (SW3) is depressed, a one-shot multivibrator circuit (15) is actuated to output one pulse. When the pulse enters a self-holding circuit (16), the self-holding circuit (16) is self-held to output an H-level signal until reset. As a result, a transistor (17) is turned on to actuate a relay (R1) for lowering a ram. When the ram reaches the lower limit position, a lower limit switch (LS4) is opened, so that a signal from a one-shot multivibrator circuit (18) causes a self holding circuit (21) to self-hold an H-level signal. The signal is delayed by a delay circuit (22) to turn a transistor (23) on. Therefore, a relay (R2) for raising the ram is actuated. Restarting will not be effected due to the operation of the one-shot multivibrator circuit (15) even when the start switch is kept depressed. Also, the service life of a valve changeover mechanism can be extended owing to the operation of the delay circuit (22). Further, erroneous operations can be prevented by operations of a delay circuit (19) and an AND circuit (24) even when the lower limit switch (LS4) chatters.

摘要： In a press-driven tool module, in particular press-driven cross-punching or bending unit, a tool (18) mountable on a slide (9) is movable in any direction against the action of a restoring, integrated pneumatic spring, and the tool (18) carrying slide (9) may be actuated by a vertically movable press slide (17). For that purpose, a vertically guided plunger (23) arranged in a power cylinder (K) may be actuated by the press slide (17) by means of a piston rod (3) and acts upon a hydraulic medium (M) in an underlying displacement chamber (24). The displacement chamber (24) is connected by a high pressure pipe (25) to the work chamber (22) of a working cylinder (A) whose piston rod (9) bears the tool. In a preferred embodiment, the power cylinder (K) and the working cylinder (A) may be mounted apart from each other and linked to each other by a flexible high pressure pipe.

摘要： A breakthrough buffer for presses, for reducing noise or vibration occuring during blanking using a mechanical press, and a control method therefor. The apparatus is provided with a buffer body (20) disposed below the punch (3) of a press (1) and cushioning the punch during the breakthrough of the press, a timing regulator (40) connected to the buffer body and regulating the timing of the same during the breakthrough of the press, and a controller (60) adapted to send out a command for a regulating position to this regulator. The noise or vibration occuring during the breakthrough of the press is detected, and a command signal is sent out from the controller (60) to the timing regulator (40) to regulate the timing of the buffer body (20), whereby noise or vibration occuring during the breakthrough of the press is minimized.

摘要： Es wird eine hydraulische Presse vorgeschlagen, die vor, während und nach dem Arbeitshub ständig vorgespannt ist, so daß von einer dynamischen Vorspannung der Presse gesprochen werden kann. Durch diese dynamische Vorspannung wird ein ständiges Spannen und Entspannen, wie dies bei herkömmlichen Pressen auftritt vermieden, wodurch sich eine Energieeinsparung und eine Schnittschlagdämpfung ergeben.
