Abstract

Die vorliegende Erfindung betrifft eine Ringpresse, umfassend einen Dorn (24), über den ein zu pressendes ringförmiges Werkstück in Axialrichtung (BA) der Ringpresse (18) zuführbar ist und an dem das Werkstück abstützbar ist, mehrere in Radialrichtung (R) geführt bewegliche Presselemente (44), mit denen Druck (24) auf das Werkstück ausübbar ist, und eine in Umfangsrichtung relativ zu den Presselementen (44) drehbare Druckerzeugungsanordnung (26), bei deren Verdrehung relativ zu den Presselementen (44) die Presselemente (44) von einer Freigabestellung in eine Pressstellung bewegt werden, wobei die Druckerzeugungsanordnung (26) mehrere Rollen (42) umfasst, die zur Erzeugung von Druck über eine durch die jeweiligen radialen äußeren Ränder (50) der Presselemente (44) gebildete kontinuierliche Umfangsbahn (60) abgerollt werden und wobei die Druckerzeugungsanordnung (26) einen Laufring (32) umfasst, an dessen radialer Innenseite sich die Rollen (42) abwälzen. Erfindungsgemäß wird vorgeschlagen, dass sie einen Antrieb (36) umfasst, der derart ausgebildet ist, dass er getriebefrei mit dem Laufring (32) koppelbar oder gekoppelt ist, um die vom Antrieb (32) erzeugte Drehzahl bzw. das erzeugte Drehmoment normalerweise unverändert auf den Laufring (32) zu übertragen. Ferner betrifft die Erfindung eine Arbeitsmaschine mit einer erfindungsgemäßen Ringpresse.

The present invention relates to a ring press, comprising a mandrel (24) via which an annular workpiece to be pressed can be fed in the axial direction (BA) of the ring press (18) and on which the workpiece can be supported, several pressing elements guided in the radial direction (R) (44), with which pressure (24) is exerted on the workpiece, and a circumferentially relative to the pressing elements (44) rotatable pressure generating arrangement (26), when rotated relative to the pressing elements (44), the pressing elements (44) of a Release position are moved to a pressing position, wherein the pressure generating assembly (26) comprises a plurality of rollers (42) which are unrolled to generate pressure via a continuous circumferential path (60) formed by the respective radial outer edges (50) of the pressing elements (44) and wherein the pressure generating arrangement (26) comprises a race (32), on the radial inside of which roll the rollers (42). According to the invention, it is proposed that it comprises a drive (36) which is designed such that it can be coupled or coupled to the raceway (32) in a gear-free manner in order to keep the speed or torque generated by the drive (32) normally unchanged To transfer race (32). Furthermore, the invention relates to a working machine with a ring press according to the invention.
