Abstract
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zur Ausbalancierung des Pressenstoessels, wobei der Pressenstoessel an Hohlstangen befestigt ist, die ihrerseits mittels Kolben in Druckmittelzylindern abgestuetzt sind, die am Kopfstueck oder Staender der Presse angeordnet sind. Diese Hohlstangen koennen bei Ueberlastung brechen, wodurch ein erheblicher Schaden auftreten kann. Hier setzt nun die vorliegende Erfindung ein und hat sich zur Aufgabe gestellt, eine in ihrem Aufbau moeglichst einfache Bruchsicherung zu schaffen. Hierzu wird erfindungsgemaess bei einer Vorrichtung der eingangs beschriebenen Ausfuehrung vorgeschlagen, dass innerhalb der Hohlstangen Bruchsicherungen vorgesehen sind. Fig. 1The present invention relates to a device for balancing the press ram, wherein the press ram is attached to hollow rods, which in turn are supported by means of pistons in pressure medium cylinders, which are arranged on the head piece or stand of the press. These hollow rods can break when overloaded, which can cause considerable damage. Here is where the present invention and has set itself the task of creating a possible simple in their construction breakage protection. For this purpose, it is proposed according to the invention in a device of the embodiment described at the outset that breakages be provided inside the hollow rods. Fig. 1
