"Hydraulik-Plunger für das spielfreie Verspannen der Sinbaustücke in Walz^erusxen""Hydraulic plunger for backlash-free clamping of the sin components to waltz "
Zum spielfreien Verspannen der Einbausxücke in Walzgerüsten werden üblicherweise Hydraulik-Plunger verwendet, die in die Einbaustücke eingebaut sind. Hierbei besteht die Schwierigkeit, dai3 zur Zufuhr des Druckmediums Rohre oder Schläuche erforderlica werden, die mit der Energiequelle in Verbindung stehen. Diese Rohre oder Schläuche unterliegen der Beschädigungsgefahr und führen dadurch zur Unterbrechung des Walzvorganges.For backlash-free clamping of the installation gap in roll stands Hydraulic plungers are commonly used, which are inserted into the Chocks are installed. The difficulty here is dai3 pipes or hoses are required to supply the pressure medium associated with the energy source. These pipes or hoses are subject to the risk of damage and thus lead to the interruption of the rolling process.

Die Wirkungsweise der Vorrichtung 1st folgende: Zunächst wird der-Stickstoffraum 5 über den Füllenscaluß 7 auf einen vorbestimmten Druck gebracht und die in dem noch freien ölraum 6 befindliche Luft über die Entlüftun^ssehraube 8 abgelassen. Sodann wird in den Ölraum 6 über den Füllanschluß 9 so lange Öl eingepumpt, bis sich der Zylinderraum 2 ^e füllt- hat, und blasenfreies Öl an der Entlüftungsschraube 8 austritt. Nach Verschließen dieser Schraube wird der vorherbestimmte Druck im Zylinderraum durch weiteres Pumpen eingestellt. Der Kolben 4 schiebt sich hierdurch in den Druckraum 5 ein und erhöht den Stickstofidruck, der die Verspannunc der Walzen bewirkt.The mode of operation of the device is as follows: First of all, the nitrogen space 5 is opened over the filling cylinder 7 brought a predetermined pressure and that in the still free The air located in the oil chamber 6 is discharged via the vent 8. Then oil is pumped into the oil chamber 6 via the filling connection 9 until the cylinder chamber 2 ^ e has been filled, and bubble-free oil emerges from the vent screw 8. To Closing this screw, the predetermined pressure in the cylinder chamber is set by further pumping. The piston 4 This pushes itself into the pressure chamber 5 and increases the Nitrogen pressure, which causes the rollers to be tensioned.
