Abstract
Description
Die Erfindung betrifft einen Arbeitszylinder, insbesondere zur Verwendung im Karoseriebau der Kfz-Industrie, für ein unter Druck stehendes Fluid, mit einem Zylinder und einem darin längsverschieblich und dichtend geführten Kolben, der einstückig mit einer Kolbenstange verbunden ist, die abgedichtet aus dem Zylinder herausgeführt ist und unter Zwischenschaltung von Getriebeteilen wie Lenker, Parallelogrammgetriebe, Kniehebelgelenkanordnung oder dergleichen Vorrichtungen zum Spannen und/oder Fügen und/oder Stanzen und/oder Prägen und/oder Schweißen und/oder Lochen und/oder Clinchen, antreibt.The The invention relates to a working cylinder, in particular for use in the Karoseriebau the car industry, for a pressurized Fluid, with a cylinder and a longitudinally displaceable and sealing out Piston, the one-piece connected to a piston rod which is sealed from the cylinder led out is and with the interposition of transmission parts such as handlebars, parallelogram, Toggle joint arrangement or the like devices for clamping and / or joining and / or punching and / or embossing and / or welding and / or punching and / or clinching drives.

Der Erfindung liegt die Aufgabe zugrunde, einen Arbeitszylinder mit günstiger Energiebilanz zu schaffen.Of the Invention is the object of a working cylinder with better Energy balance.
Lösung der AufgabeSolution of the task
Diese Aufgabe wird durch einen Arbeitzylinder mit den im Patentanspruch 1 angegebenen Merkmalen gelöst.These Task is by a working cylinder with the in claim 1 specified characteristics solved.
Einige VorteileSome advantages
Ein erfindungsgemäßer Arbeitszylinder lässt sich mit besonderem Vorteil zum Antrieb von Kniehebelspannvorrichtungen, Clinchvorrichtungen und Zentriervorrichtungen im Karosseriebau der Kfz-Industrie einsetzen. Dort werden derartige durch Kniehebel angetriebene Vorrichtungen in großer Stückzahl in Fertigungslinien verwendet, so dass normalerweise große Druckluftmengen zum Einsatz kommen, die im Grunde genommen während des Leerhubes gar nicht benötigt werden. Auch werden die auf der Kolbenstangenseite befindlichen Luftmengen, die zum Teil auch mit Öl durch den Drucklufterzeuger verunreinigt sind, stets in die freie Atmosphäre abgelassen. Dagegen wird bei dem erfindungsgemäßen Arbeitskolben eine äußerst geringe Druckluftmenge beim Einsetzen des Krafthubes im Bedarfsfalle in die Atmosphäre entlüftet, da der Krafthub erst wenige Millimeter vor dem Ende des Gesamthubes des Kolbens, der zum Beispiel zum Antrieb eines Spannarmes einer Kniehebelspannvorrichtung eingesetzt wird, mit dem vollen Druckmitteldruck beaufschlagt. Nur diese sehr geringe auf der Kolbenstangenseite befindliche Druckluftmenge strömt im Bedarfsfalle in die Atmosphäre, die allerdings nur einen Bruchteil der Druckluftmenge beträgt, die beim Stand der Technik in die freie Atmosphäre ausgeblasen wird. Bei den großen Stückzahlen derartiger Spannvorrichtungen, die im Karosseriebau der Kfz-Industrie weltweit, aber auch nur in einer Volkswirtschaft einer Industrienation eingesetzt werden, ergibt sich bei Verwendung eines erfindungsgemäßen Arbeitszylinders eine spürbare Entlastung der Umwelt, besonders wenn man eine Energiebilanz über einen gewissen Zeitraum, zum Beispiel über ein Jahr, aufstellt. Zwischen Fluidquelle und Steuerventil ist ein weiteres, insbesondere als Mehrwegeventil, ausgebildetes Steuerventil, angeordnet. Die Ventile sind innerhalb des Arbeitszylinders zusammen mit den sie verbindenden Kanälen baulich vereinheitlicht angeordnet.One inventive cylinder let yourself with particular advantage for driving toggle lever tensioning devices, Clinching devices and centering devices in the body of the Use automotive industry. There such are driven by toggle Devices in large quantity used in production lines, so usually large amounts of compressed air are basically not used during the idle stroke needed become. Also located on the piston rod side Air volumes, some of them with oil from the compressed air generator contaminated, always released into the atmosphere. On the other hand in the working piston according to the invention a very small one Amount of compressed air when inserting the power stroke in case of need in the atmosphere vented, because the power stroke only a few millimeters before the end of the total stroke of Piston, for example, to drive a clamping arm of a toggle lever device is used, acted upon by the full pressure medium pressure. Just this very small amount of compressed air located on the piston rod side flows if necessary in the atmosphere, which is only a fraction of the amount of compressed air, the blown in the prior art in the free atmosphere. Both huge numbers Such tensioning devices used in the bodywork of the automotive industry worldwide, but only in an economy of an industrial nation can be used, results when using a working cylinder according to the invention a noticeable Relieving the environment, especially if you have an energy balance over one certain period, for example over a year, sets up. Between fluid source and control valve is a further, in particular as a multi-way valve, formed control valve, arranged. The valves are together inside the working cylinder with the channels connecting them arranged structurally unified.
Weitere vorteilhafte AusführungsformenFurther advantageous embodiments
Weitere vorteilhafte Ausführungen sind in den Patentansprüchen 2 und 3 beschrieben.Further advantageous embodiments are in the claims 2 and 3 described.
Bei Ausgestaltung gemäß Patentanspruch 2 ist das Steuerventil als Mehrwegeventil ausgebildet. Das bei dem Arbeitszylinder verwendete durch den Kolben oder dessen Kolbenstange betätigte Ventil wird sowohl in Richtung des Krafthubes als auch in der entgegengesetzten Richtung jeweils bis zu seiner Betätigung durch den Kolben bzw. die Kolbenstange durch den Fluiddruck, der von der Fluidquelle ankommt, in seiner jeweiligen Steuerstellung gehalten.at Embodiment according to claim 2, the control valve is designed as a multi-way valve. That at the Working cylinder used by the piston or its piston rod actuated Valve becomes both in the direction of the power stroke and in the opposite Direction until it is actuated by the piston or the piston rod by the fluid pressure arriving from the fluid source, held in its respective tax position.
Bei der Ausführungsform nach Patentanspruch 3 dient der Arbeitszylinder zum Antrieb einer Kniehebelspannvorrichtung, deren Kolbenhub stufenlos in entge gengesetzten Richtungen um ein begrenztes Maß und damit auch die Winkelverstellung des Spannarmes, verstellbar ist.at the embodiment according to claim 3 of the working cylinder is used to drive a toggle lever jig, the piston stroke steplessly in entge gengesetzten directions to a limited measure and so that the angle adjustment of the clamping arm, is adjustable.
