Description
Hydraulische Presse mit unbeweglich am Pressengestell befestigtem Druckzylinder Die Erfindung bezieht sich auf eine hydraulische Presse, deren Druck bei unverändertem Druck der Preßflüssigkeit in ;seiner Höhe innerhalb weiter Grenzen eingestellt werden kann; sie besteht darin, daß der Kolben des mit dem Pressengestell unbeweglich verbundenen Zylinders durch ein Gestänge mit dem verstellbaren Angriffspunkt eines den Preßstempel bewegenden Hebels verbunden ist und der Drehpunkt des Hebels unbeweglich am Pressengestell gelagert ist.Hydraulic press with fixed fixed to the press frame Pressure cylinder The invention relates to a hydraulic press whose pressure with unchanged pressure of the press liquid in; its height within wide limits can be adjusted; it consists in the fact that the piston of the press frame immovably connected cylinder by a linkage with the adjustable point of application a lever moving the ram is connected and the pivot point of the lever is immovably mounted on the press frame.
Die Zeichnung zeigt schematisch ein Ausführungsbeispiel der Erfindung. An dem Pressengestell a ist der Zylinder b unbeweglich befestigt. Sein Kolben c ist in dem Punkte d gelenkig mit zwei parallelen Schubstangen e verbunden, die beiderseits am Zylinder b außen vorbeigehen. Mit der gleichen Mittellinie wie der Zylinder b ist am Pressengestell der Rückzugzylinder f befestigt, dessen zugehöriger Kolben g mit dem Kolben c fest verbunden ist.The drawing shows schematically an embodiment of the invention. At the press frame of a cylinder is fixed immovably b. Its piston c is articulated at point d with two parallel push rods e, which pass outside the cylinder b on both sides. With the same center line as the cylinder b, the retraction cylinder f is attached to the press frame, the associated piston g of which is firmly connected to the piston c.
Der Drehpunkt h des Hebels i ist gleichfalls unbeweglich am Pressengestell gelagert. Der Hebel i ist zweiarmig. An seinem einen Arm ist der Angriffspunkt k der Schubstange e mittels der Schraubenspindel l verstellbar. Der andere Arm greift an dem Preßstempel in an und bewegt ihn in bezug auf den Gegenhalter n. Die Zylinder b und f können, wie üblich, nach Belieben mit der Druckmittelzuleitung oder mit dem Abwasser verbunden werden.The pivot point h of the lever i is also immovably mounted on the press frame. The lever i has two arms. On one of its arms, the point of application k of the push rod e can be adjusted by means of the screw spindle l. The other arm engages the ram in and moves it with respect to the counter holder n. The cylinders b and f can, as usual, be connected at will with the pressure medium supply line or with the waste water.
Je nachdem der Angriffspunkt k an dem Hebel i dem Drehpunkt h genähert oder davon entfernt wird, wird der von dem Preßstempel in ausgeübte Druck niedriger oder höher. Das Verhältnis der kleinsten zur größten Druckhöhe beträgt bei dem gezeichneten Ausführungsbeispiel ungefähr z :3.Depending on the point of application k on the lever i approaches the pivot point h or is removed therefrom, the pressure exerted by the ram becomes lower or higher. The ratio of the smallest to the largest pressure height is in the one shown Embodiment approximately z: 3.
Die Erfindung bietet folgende Vorteile: Die Verbindung zwischen den beiden Zylindern und der Zu- und Abflußleitung des Druckmittels ist ortsfest, daher einfach, sicher und keiner Abnutzung unterworfen. Ebenso ist die Verbindung zwischen den Zylindern und dem Pressengestell einfach, mit üblichen Mitteln widerstandsfähig zu gestalten und sicher. Dasselbe gilt von der Lagerung des Hebeldrehpunktes. Auch das Gestänge bietet weder unsichere noch kostspielige Verbindungen. Zur Einstellung der Druckhöhe braucht nur das Gestänge e verstellt zu werden. Diese Verstellung nimmt nur wenig Raum in Anspruch, und zwar an einer Stelle, wo andere Zwecke nicht dadurch beeinträchtigt werden.The invention offers the following advantages: The connection between the both cylinders and the inlet and outlet line of the pressure medium is stationary, therefore simple, safe and not subject to wear and tear. Likewise is the connection between the cylinders and the press frame simple, resistant by conventional means design and secure. The same applies to the bearing of the fulcrum. Even the linkage provides neither unsafe nor costly connections. To recruitment the pressure height only needs the linkage e to be adjusted. This adjustment takes up very little space in a place where other purposes cannot be affected.
