Abstract
Description
Die Erfindung beschreibt die Bauart einer Presseneinrichtung, aus mindestens einem Kurzhub-Pressenzylinder mit Kurzhubkolben, die durch eine besondere Rückführeinrichtung mit kleinster Bauhöhe auskommt und zudem noch planmäßig leichte Kippbewegungen des Kurzhubkolbens zulässt.The Invention describes the design of a press device, at least a short-stroke press cylinder with short-stroke piston, which by a special return device with the smallest height gets along and also scheduled light Tilting movements of the short-stroke piston allows.
Die Kolben in Zylindern von Pressenrahmen sind i.d.R. lang und massiv ausgeführt, so dass der längliche Kolben innerhalb des führenden Zylinderrohres durch Druckumschaltung hin und her geführt werden kann. Dabei weisen diese Kolben einen langen Führungsbereich auf, damit sie sich in der Zylinderführung nicht verkanten können. Mit dieser langgestreckten Ausführungsform führen diese Zylinder zu hohen Pressenrahmen, um den Zylinder mitsamt des Kolbens aufnehmen zu können. Die Kolben haben auf ihrer Kolbenstirnfläche keine Möglichkeit sich flächig einer leichten Unebenheit oder Durchbiegung des Tisches anzupassen. Dies gilt besonders für Kolben mit großen Durchmessern. Der niedergedrückte Flächenbereich wird dann sehr ungleichmäßig nur über den Rand des Kolbenfläche belastet. Würde der Kolben dennoch sehr flach ausgeführt, gibt es innerhalb des Zylinders keine Möglichkeit den Kolben nach dem Ausfahren wieder selbständig in die Ausgangsposition zurückzufahren.The Pistons in cylinders of press frames are i.d.R. long and massive executed so that the elongated Piston within the leading Cylinder tube by pressure change back and forth can. These pistons have a long guide area, so they in the cylinder guide can not tilt. With this elongated embodiment to lead these cylinders to high press frame to the cylinder together with the To be able to record the piston. The pistons have on their piston face no possibility flat one slight unevenness or sagging of the table. This especially for Piston with big Diameters. The depressed area then becomes very uneven only over the Edge of the piston surface loaded. Would the piston is still very flat, there are within the Cylinder no way the piston after extension again independently in the starting position cut back.
Dieses Problem wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.This Problem is solved by the features specified in claim 1 solved.
