Description
Bei aus teleskopartig ineinander geführten Rohren bestehenden Grubenstempeln sind sogenannte Stempelklemmringschlösser bekannt, dereni Gurte als einseitig offene Schellenbänder ausgebildet sind. Hierfür wurde bereits vorgeschlagen, das eine Bandende mit einem Ausschnitt zu versehen, in den sich das andere Bandende einlegt, wobei die Enden derartige Verstärkungen aufweisen:, daß ein Keil zur Schließung des Bandes zwischen die mit Nuten versehenen Verstärkungen eingetrieben werden kann:. Nachteilig hierbei ist, daß die aufzubringende Kraft von der Sorgfalt des Bedienenden abhängig ist, d. h. die jeweilige Eindringtiefe des Keils ist für die aufgebrachte Schließkraft ausschlaggebend. Im Betrieb wirkt sich diese Tatsache darin aus, daß jedes Schloß miteiner anderen Kraft gespannt wird.In the case of pit punches consisting of tubes guided one inside the other in a telescopic manner so-called stamp ring locks are known, whose belts are open on one side Clamp bands are formed. For this it has already been suggested that one end of the tape to be provided with a cutout into which the other end of the tape is inserted, whereby the ends have such reinforcements: that a wedge to close the band between the grooved reinforcements can be driven :. Disadvantageous here it is that the force to be applied depends on the care of the operator is, d. H. the respective penetration depth of the wedge is for the applied closing force crucial. In operation, this fact has the effect that every lock is tensioned with a different force.
Die Erfindung beseitigt diesen Nachteil dadurch, daß die Verspannung der Schloßgurte hydraulisch erfolgt. Auf diese Weise ist das Maß der Verspannung genau zu bestimmen, und alle Schlösser werden mit der gleichen Kraft verspannt. Damit größere Fabrikationstoleranzen in den. einzelnen Schloßteilen und der Hydraulik zugelassen werden können, ist in weiterer Ausgestaltung der Erfindung jeder Schloßgurt durch einen für sich arbeitenden Druckkolben. zu spannen. Auch kann[ zu dem gleichen Zweck der Oberstempel in an sich bekannter Weise konisch ausgebildet sein. Die Schloßsteuerung erfolgt durch ein Überdruckventil und das Rauben des Stempels durch eine Lüftungsschraube, wie, sie bei Grubenstempeln mit hydraulisch betätigter Verspannung ebenfalls an sich bekannt sind.The invention eliminates this disadvantage in that the bracing the buckle belt is done hydraulically. That way is the amount of tension to be precisely determined, and all locks are braced with the same force. This means that greater manufacturing tolerances in the. individual lock parts and the hydraulics can be approved, each buckle strap is in a further embodiment of the invention by a pressure piston that works for itself. to tension. Also can [to the same Purpose of the upper punch to be conical in a manner known per se. The lock control takes place through a pressure relief valve and the ram is stolen through a ventilation screw, like, they also apply to pit punches with hydraulically actuated bracing are known.
In der Zeichnung ist der Gegenstand der Erfin Jung in drei Abbildungen dargestellt.In the drawing, the subject of the inventor Jung is shown in three images shown.
Abb. i zeigt den Grubenstempel im Längsschnitt; Abb. 2 ist ein Schnitt nach der Linie A-B in Abb. i ; Abb. 3 zeigt die hydraulische Spannvorrichtung im Schnitt.Fig. I shows the pit punch in longitudinal section; Fig. 2 is a section according to the line A-B in Fig. i; Fig. 3 shows the hydraulic clamping device in Cut.
Wie aus den Abb. i und 2 ersichtlich ist, wird das Oberstempelrohr i über die Schloßgurte. 2 des Klemmringschlosses mit dem in seinem Oberteil geschlitzten Unterstempelrohr 3 verspannt. Zwischen Oberstempel und Unterstempel ist im vorliegenden Fall die aus Segmenten bestehende Reibvorrichtung 4 geschaltet. Auf diese kann gegebenenfalls verzichtet werden. Die Reibsegmente stehen beispielsweise unter der Wirkung von Spreizfedern 5, die stets eine auf Lösen gerichtete Kraft auf die Reibvorrichtung ausüben. Der Oberstempel ist leicht konisch gestaltet, damit bei einem Druckabfall eire selbsttätiges Nachspannen erfolgt.As can be seen from Figs. I and 2, the upper punch tube i over the buckle straps. 2 of the clamping ring lock with the one slotted in its upper part Lower punch tube 3 clamped. Between the upper stamp and the lower stamp is in the present If the friction device 4 consisting of segments is switched. On this, if necessary be waived. The friction segments are, for example, under the effect of Spreading springs 5, which always apply a force on the friction device aimed at loosening exercise. The upper punch has a slightly conical design, so that in the event of a pressure drop Automatic retensioning takes place.
Bei der in Abb. 3 im vergrößerten Maßstab dargestellten Spannvorrichtung werden mittels der Druckschrauben bzw. des Druckgebers 6 über den Druckraum 7 die beiden Kolben 8 beaufschlagt. Statt der Druckschraube kann gegebenenfalls auch eine kleine Hochdruckpumpe Verwendung finden. Der Druckraum 7 steht über eine Zuführungsleitung mit einem Überdruckventil 9 in Verbindung, das den Flüssigkeitsdruck entsprechend seiner jeweiligen Einstellung regelt. Gegenüber dem oberen Druckkolben befindet sich eine weitere Zuführungsleitung zu der Lüftungsschraube io. Bei Überschreitung des vorgesehenen Stempeldruckes strömt die Druckflüssigkeit über das Überdruckventil 9 unter Überwindung des unter dem Druck der Feder 12 stehenden Kolbens 13 in den. Vorratsraum i i. Auch beim Öffnen der Lüftungsschraube io enrtweicht die Druckflüssigkeit, in diesem Fall über den oberen Kanal, in den Vorratsraum i i. Um den Stempel erneut zu setzen, wird der Druckgeber 6 zurückgeschraubt. Gleichzeitig drückt der Kolben! 13 bei geöffneter Lüftungsschraube io die Druckflüssigkeit wieder in den Arbeitsraum 7. Sodann wird die Lüftungsschraube io geschlossen und der erforderliche Druck durch Anziehen des Druckgebers 6 aufgebracht.In the clamping device shown in Fig. 3 on an enlarged scale are by means of the pressure screws or the pressure transducer 6 via the pressure chamber 7 the applied to both pistons 8. Instead of the pressure screw, a small high pressure pump can be used. The pressure chamber 7 is above a supply line with a pressure relief valve 9 in connection, which the liquid pressure accordingly its respective setting. Located opposite the upper plunger Another supply line to the ventilation screw io. When exceeded of the intended ram pressure, the hydraulic fluid flows over the pressure relief valve 9 by overcoming the piston 13 under the pressure of the spring 12 in the. Pantry i i. The hydraulic fluid also softens when the ventilation screw is opened, in this case via the upper channel into the storage space i i. To the stamp again to set, the pressure transducer 6 is screwed back. At the same time the piston pushes! 13 the hydraulic fluid is returned to the working area with the ventilation screw open 7. Then the ventilation screw is closed and the required pressure is applied Tightening the pressure transducer 6 applied.
