Betr.: -Schutzeinrichtung für Pressen-Beschreibung: Re. : -Protective device for presses-description:

Die angemeldete Vorrichtung besteht aus einer Gleitführung, welche als einseitig wirkender Hydraulikzylinder ausgebildet ist (7,8); einem 2-Wege-Ventil (6) mit Druckstück (5), dem gefedertem (9) Tastrahmen (11) und Stößel (io) mit Druckrolle (4)The registered device consists of a sliding guide, which is designed as a unidirectional hydraulic cylinder is (7.8); a 2-way valve (6) with pressure piece (5), the spring-loaded (9) feeler frame (11) and plunger (io) with pressure roller (4)

Bei Betätigung des Tastrahmens (11) wird das Ventil (6) geschlossen und das Öl im Zylinderraum (8) blockiert T^rzögerungsfrei die gesamte Gleitführung.When the sensing frame (11) is actuated, the valve (6) is closed and the oil in the cylinder chamber (8) blocks without delay the entire sliding guide.

Die Vorrichtung dient dem Schutz von Bedienungspersonal, insbesondere bei sehne Häufend en Pressen, wo eine Absicherung im Gefahrenbereich mit Fotozellen und üblicher Schnellbremsung oder Umsteuerung zu träge ist. Als Nebeneffekt ist noch der bedingte Schutz meist teurer Werkzeuge anzusehen, da die Vorrichtung auch dann in Kraft tritt, wenn an Stelle der Hände ein Gegenstand zwischen die Werkzeuge kommen sollte.The device is used to protect operating personnel, in particular with tendons accumulating in presses, where protection in the danger area with photocells and the usual rapid braking or reversal is too sluggish. A side effect is the limited protection of mostly expensive tools, because the Device also comes into force if an object should come between the tools instead of the hands.
