Claims (1)

<Desc/Clms Page number 3> B.angeordnet sind, dass ein über die gesamte Länge des Rammrohres (1) verschiebbarer Druckring (4) vorgesehen ist, dessen Innendurchmesser etwa gleich ist dem Aussendurchmesser des Rammrohres (1) und der an seiner Innenseite ebensoviele Aussparungen (9) aufweist, wie Nocken (2) in einer Reihe vorhanden sind, wobei die Aussparungen (9) etwa gleiche Abmessungen wie die Nocken (2) besitzen, dass eine Vorrichtung zum Verdrehen des Druckringes (4) gegenüber dem Rammrohr (1) vorgesehen ist, wodurch die zwischen den Aussparungen (9) des Druckringes (4) liegenden Vorsprünge (8) unter die EMI3.1 eine weitere Hubhöhe der hydraulischen Pressen möglich ist. <Desc / Clms Page number 3> B. arranged that a pressure ring (4) that can be displaced over the entire length of the ram pipe (1) is provided, the inner diameter of which is approximately the same as the outer diameter of the ram pipe (1) and which has as many recesses (9) on its inside as cams (2) are present in a row, the recesses (9) having approximately the same dimensions as the cams (2) that a device for rotating the pressure ring (4) relative to the ram pipe (1) is provided, whereby the between the recesses (9) of the pressure ring (4) lying projections (8) under the EMI3.1 a further lifting height of the hydraulic presses is possible.
