Abstract

The pneumatic cylinder generates multiple piston power. It comprising a cylinder housing with a bore to guide the piston and pusher rod, a mechanical lever system and a closure cover. The introduction of air pressure into the lower region of the cylinder housing (1) causes the piston (2) to slide upwards along the rod (3). A lever system (4) in the upper region of the cylinder creates an opposite downwards movement. Alternatively, the piston can be subject to air pressure from above. USE/ADVANTAGE - Alternative to a hydraulic cylinder in environmentally sensitive applications. The cylinder unit has few working parts and although compact, exerts considerable force.

Description

Die Erfindung bezieht sich auf einen Pneumatikzylinder, insbesondere Pneumatik-Kurzhub-Zylinder mit mehrfacher Kolbenkraft und mit den Außenabmessungen eines Normzylin­ ders.The invention relates to a pneumatic cylinder, especially pneumatic short-stroke cylinders with multiple Piston force and with the outside dimensions of a Normzylin otherwise.

Pneumatikzylinder sind im Vergleich zu Hydro-Zylinder ein sehr wirtschaftliches, umweltfreundliches und beliebtes Maschinenelement, das in den verschiedensten Bereichen der Technik Anwendung findet. Doch überall dort, wo hohe Kräfte und kleine Einbauräume gefordert sind, müssen Pneumatik­ zylinder leider passen.Pneumatic cylinders are one compared to hydraulic cylinders very economical, environmentally friendly and popular Machine element that is used in a wide variety of areas Technology is used. But wherever high forces and small installation spaces are required, pneumatics cylinder unfortunately fit.

Hier setzt nun die Erfindung ein. Sie hat es sich zur Auf­ gabe gemacht der eingangs genannten Art von Pneumatikzylin­ der dahingehend zu entwickeln, daß diese zwei Komponenten, kleine Baugröße, große Kraft, erfüllt werden. Normalerweise arbeitet ein herkömmlicher Pneumatikzylinder mit einem Kolben und einer Kolbenstange, die bei Erzeugung eines Luftüberdruckes in Längsrichtung nach vorne ausfährt und eine Kraft, die von der Kolbenfläche und dem Luft­ druck abhängig ist, aufweist.This is where the invention begins. She has it open made the type of pneumatic cylinder mentioned above to develop in such a way that these two components, small size, great power. A conventional pneumatic cylinder normally works with a piston and a piston rod, which when generating of an air overpressure extends forward in the longitudinal direction and a force from the piston surface and the air pressure is dependent.

Bei diesem eingangs erwähnten Zylinder wird die Schubkraft dadurch erzeugt, daß der Kolben von unten mit Druckluft beaufschlagt wird, so daß er auf der Schubstange nach oben gleitet und die wirkende Druckkraft über ein geeignetes Hebelsystem auf die Schubstange überträgt, die somit eine entsprechende Schubkraft und Hub nach unten erfährt. Durch diese Funktion des Zylinders wird eine Kraftumlen­ kung abhängig vom zuführenden Luftdruck, der Kolbenfläche, dem Hebelverhältnis, erzwungen, wobei daraus eine einfache oder je nach Hebelverhältnis eine mehrfache Schubkraft re­ sultiert.In this cylinder mentioned above, the thrust generated by the piston from below with compressed air is applied so that it is on the push rod upwards slides and the acting pressure force over a suitable Lever system transfers to the push rod, which is therefore a experiences corresponding thrust and downward stroke. This function of the cylinder turns the force depending on the supply air pressure, the piston area, the leverage ratio, being a simple one or depending on the leverage ratio, a multiple thrust right results.

Im Prinzip kann diese Funktion auch umgekehrt wirken. Der Kolben wird von oben mit Druckluft beaufschlagt und gleitet nach unten, überträgt dabei die von oben wirkende Druckkraft auf das im unteren Bereich des Zylindergehäuses befindliche Hebelsystem und kann somit den gleiche Wirkung erreichen. (ohne zeichnerische Darstellung) Die Rückholung der Schubstange und des Kolbens in ihre Aus­ gangsposition kann bei beiden Ausführungen mittels einer Druckfeder, die zwischen Kolben und der Schubstange plaziert ist, oder die Schubstange ist dementsprechend ausgebildet, daß die Rückholung durch beaufschlagen von Druckluft erreicht werden kann.In principle, this function can also work in reverse. The Compressed air is applied to the piston from above and slides downwards, transmits the pressure force acting from above to the one located in the lower area of the cylinder housing Lever system and can therefore achieve the same effect. (without graphic representation) Retrieval of the push rod and piston in their out aisle position can be achieved with a Compression spring placed between the piston and the push rod is, or the push rod is designed accordingly, that the return is achieved by applying compressed air can be.
