Description

Die Erfindung bezieht sich auf ein Schloß für aus Ober- und Unterteil bestehende Grubenstempel, das durch eine Kammer mit einer Füllung aus einem ftießf@ihi«en, elastischen Werkstoff, insbesondere aus Gummi, zur Druckausübung auf den verschieb- baren Stempelteil gebildet ist, nach Patent 831 834. Die in dem Patent 831 834 gezeigten Ausfüh- rungsbeispiele zeigen eine Zwischenlage zwischen der Kammerfüllung und dem verschiebbaren Stem- pelteil, die beispielsweise aus einem elastischen Grund der Kammer oder aus einer elastischen Aus- kleidung der Druckkammer bestehen kann. \acli der Erfindung greift die Füllung unmittel- har atn verschiebbaren Stempelteil an. Da sich tließfiihiger, elastischer Werkstoff, wie Gummi, mit einem sehr hohen Reibungskoeffizienten herstellen läßt, zu welchem noch eine erhebliche Verschleiß- festigkeit kommen kann, wird hierdurch der Schloß- angriff verbessert. Gleichzeitig tritt eine Ver- einfachung des Schlosses ein. Die Zeichnung veranschaulicht ein Ausführungs- beispiel der Erfindung. Die Druckkammer besitzt eine Füllung 25 aus Gummi. Diese Füllung greift unmittelbar am verschiebbaren Stempeloberteil r an. Bei dem Ausführungsbeispiel wird der Druck über den Kolben 26 und der Schraube 7 erzeugt. Naturgemäß kann der Druck auch in jeder anderen Weise erzeugt werden und die Kammer jede andere geeignete Ausbildung haben. The invention relates to a lock for Upper and lower part of the existing pit stamp, the through a chamber with a filling of one ftießf @ ihi «en, elastic material, in particular from Rubber, for exerting pressure on the sliding ble stamp part is formed, according to patent 831 834. The embodiments shown in patent 831 834 examples show an intermediate layer between the chamber filling and the sliding stem pelteil, for example made of an elastic Reason of the chamber or from an elastic clothing of the pressure chamber can exist. \ acli of the invention, the filling engages directly har atn movable stamp part. That I Free-flowing, elastic material, such as rubber, with produce a very high coefficient of friction leaves, to which a considerable wear and tear strength can come, the lock attack improved. At the same time there is a simplification of the lock. The drawing illustrates an embodiment example of the invention. The pressure chamber has a filling 25 made of rubber. This filling acts directly on the displaceable upper part of the punch r. In the exemplary embodiment, the pressure is generated via the piston 26 and the screw 7. Of course, the pressure can also be generated in any other way and the chamber can have any other suitable design.
