ANORDNING TILL SKYDD FOR VERKTYGSSATS I HYDRAULISK PRESS |
摘要 |
<p>An arrangement for protecting tools in a hydraulic press against overloading if a foreign object or body is present in a tool space of the hydraulic press. A displacement or travel switch monitors at least a portion of a path of movement of a press ram with a control member providing an output signal during a predetermined movement of the press ram. A control circuit evaluates a sequence of the output signals of the displacement or travel switch and the control member in such a manner that a fault signal is formed when the additional switching device provides an output signal prior to an output signal of the displacement or travel switch. The control member is arranged in a path of force of at least one component of the hydraulic press and is constructed as a signal transducer operating virtually stationarily as a function of pressure.</p> |
