Description

Die Erfindung betrifft hydraulisch oder pneumatisch betätigte Antriebszylinder mit mehreren hintereinander in mehreren Einzelzylindem angeordneten Antriebskolben, - -di# ihre, Kraft - äber den obersten Antriebskolben nach außen übertragen.The invention relates to hydraulically or pneumatically operated drive cylinders with several drive pistons arranged one behind the other in several individual cylinders, - -di # their, force - transmitted to the outside via the top drive piston.

Hierbei waren die Antriebskolben durch Kolbenstangen und Kolbenstangenkupplungen mit Gewinde formschlüssig miteinander verbunden. Diese bekannten Einrichtungen erfordern einen großen Montageaufwand und viele Einzelteile mit genauester Herstellung.Here the drive pistons were through piston rods and piston rod couplings positively connected to one another with a thread. These known facilities require a large assembly effort and many individual parts with the most precise production.

Die Erfind#ng-hat s11 di8 Aufgabe gestellt,diesg-Nachteile zu vermeiden und einen Antriebszylinder zu sch#age:n"-; der - aus- Wesehtlich weniget-'#T,#ildn. 'mit wesentlich geringerer Genauigkeit hergestellt, und montiert werden kann.The invention has set s11 di8 the task of avoiding these disadvantages and of impacting a drive cylinder: n "-; which - essentially less - '# T, # ildn.' Manufactured with significantly lower accuracy, and can be mounted.

Erfindungsgemäß sind die AntriebskolbQ4, einzelli ohne gegenseitige"forinschlüssige.Verbü#liM& jpgeordnet und stehen an einer Seite"nur ü#e-ri'-ieii ale Ansätze miteinander in kraftschlüssiger Verbindung, wobei jeder Antriebskolben in einem eigenen Einzelzylinder angeordnet ist und jeder zentrale Ansatz der Antriebskolben den anschließenden Einzelzylinder zentriert, ferner jeder Antriebskolben, ausgenommen den obersten Antriebskolben, mit einem zentralen Kanal versehen ist, der vor seiner Mündung in den anschließenden Einzelzylinder radiale Verteilungskanäle aufweist, welche die Einzelzylinder und die Antriebskolben in bezug auf das Druckmittel parallel schalten, das durch den unteren Antriebszylinderboden zugeführt ist.According to the invention, the drive piston Q4, single cells without mutual "forinschlüssige.Verbü # liM & jpordered and stand on one side "only ü # e-ri'-ieii all approaches to each other frictional connection, with each drive piston in its own individual cylinder is arranged and each central approach of the drive piston the subsequent individual cylinder centered, furthermore every drive piston, except the uppermost drive piston, is provided with a central channel, which in front of its confluence with the subsequent Single cylinder has radial distribution channels, which the single cylinder and connect the drive piston in parallel with respect to the pressure medium that is passed through the is fed lower drive cylinder base.

In den F i g. 1 bis 4 ist die Erfindung an zwei Beispielen für Antriebszylinder zur Betätigung eines Spannbackens bei einem pneumatischen Bandvorschub näher erläutert. Es zeigt F i g. 1 den Antriebszylinder mit den einzelnen Antriebskolben im Schnitt F i g. 2 eine Ansicht des geschnittenen Kolbens von oben dargestellt, F i g. 3 und 4 in entsprechender Darstellung, einen Antriebszylinder mit Membran.In the F i g. 1 to 4 the invention is explained in more detail using two examples of drive cylinders for actuating a clamping jaw in the case of a pneumatic tape feed. It shows F i g. 1 the drive cylinder with the individual drive pistons in section F i g. 2 shows a view of the sectioned piston from above, FIG. 3 and 4 in a corresponding representation, a drive cylinder with a membrane.

Der Antriebszylinder 1 besteht, wie die F i g. 1 und 2 zeigen, aus Einzelzylindern2, die von einer Deckplatte 3 oben abgeschlossen sind. Diese Einzelzylinder 2 werden von nicht dargestellten Schraubenbolzen, die in Bohrungen14 angeordnet -si * nd, zusammengehalten. In den Einzelzylindern 2 ist je ein Antriebskolben4 angeordnet, die an der einen Seite nur -über einen zentralen zyhnderförmigen Ansatz. 5-. miteinander- in kraftschlüssiger Verbindung - stehen. Somit ist jeder Antriebskolben 4 in einem eigenen Einzelzy-li#de;, 2 --an"g-äoidüät iWd"j#'edet -#en-'-trale Ansatz 5 zentriert den anschiießenden Einzelzylinder 2. % '. Die beiden unteren -Antriebskolben 4 weisen einen zentralen Kanal 6 für das ü# der vor seiner Mündung-.in;dgn-anscWießenden Einzelzylinder 2 mit radialeii, Verteilungskanälen 7 vers - , n ist. Hierdurch kann das Druckmittel, z.B Druckluft, nicht nur zentral durch den Kanal 6 strömen, sondern wird jeweils über die gesamte Zylinderfläche verteilt. Die einzelnen Antriebskolben 4 sind durch Dichtungen 8 und ihre Ansätze 5 durch Dichtungen 9 gegenüber den Einzelzylindem 2 abgeschlossen. Durch die - radialen Y##lungskanäle 7 sind die, .'Einzelm( er 41j(I., die-.",Antriebskolben 4 in bezug auf das#"#'Druckmittel parallel geschaltet, das durch den unteren Antriebszylinderböden zugeführt ist# ' Der Ansatz 5 des obersten Antriebskolbens 4 wirkt im vorliegenden Fall als Klemmleiste und- drückt das Blechband 10 gegen den Anschlag 11, u dieses festzuhalten. In der Deckplatte 3 sind Federn 12 angeordnet, welche die einzelnen Antriebskolben 4 nach unten in ihre Ruhestellung bringen. Für die Entlüftung des Antriebszylinders sind im oberen Teil öffnungen 13 ..1'V -'- - vorgesehen. '#," J. In den F i g. 3 und 4 ist ein Antriebszylinder 15 dargestellt, der sich von der Ausbildung nach den F i g. 1 und 2 nur., dadurch unterscheidet, -daß an Stelle der Antriebsi-,dii#i ?jW'#qörnüge M#i1ranen 16 vorgesehen sind.

The drive cylinder 1 consists, as shown in FIG. 1 and 2 show individual cylinders 2 which are closed off at the top by a cover plate 3. These individual cylinder 2 are of unillustrated bolts that -si arranged in Bohrungen14 nd held together *. In each of the individual cylinders 2 a drive piston 4 is arranged, which on one side only has a central cylinder-shaped extension. 5-. with each other - in a force-fit connection - are. Thus, each drive piston 4 is in its own individual cylinder 2 - an "g-äoidüät iWd" j # 'edet - # en -'- central attachment 5 centers the subsequent individual cylinder 2. % '. The two lower drive pistons 4 have a central channel 6 for the single cylinder 2 with radial distribution channels 7 vers-, n which is connected in front of its mouth-.in; dgn-connecting individual cylinder 2. As a result, the pressure medium, for example compressed air, can not only flow centrally through the channel 6 , but is also distributed over the entire cylinder surface. The individual drive pistons 4 are closed off from the individual cylinders 2 by seals 8 and their attachments 5 by seals 9. Through the - radial Y ## lung channels 7 are the .'Einzelm (s 41j (I, -.., "Driving piston 4 with respect to the #"#'connected in parallel with pressure medium which is supplied through the lower drive cylinder bases #' The extension 5 of the uppermost drive piston 4 acts in the present case as a terminal strip and presses the sheet metal strip 10 against the stop 11 to hold it in place. In the cover plate 3 springs 12 are arranged, which the individual drive piston 4 down bring them to their rest position. For venting the The drive cylinder has openings 13 in the upper part ..1'V -'- - intended. '#, "J. In the F i g. 3 and 4 is a drive cylinder 15 shown, which differs from the training after the F i g. 1 and 2 only., Thereby differentiates, -that an Place the drive, dii # i?
