  • Patent number: 11911990
    Abstract: A housing of a radial press has a casing section and an annular end-face support disc. An annular structure is movably guided in the housing along a press axis, and multiple press jaws arranged about the press axis are supported on the support disc so as to be movably guided in the radial direction. The annular structure acts on the press jaws by means of control surfaces which are inclined relative to the press axis and which lie against press jaw counter surfaces designed in the form of sliding surfaces. The end face of the ring structure facing the support disc is designed with axial protrusions. Each control surface protrudes into the radial inner surface of one such protrusion, and the support disc has recesses which are paired with the protrusions and into which the protrusions enter when the radial press is closed.

  • Publication number: 20230116737
    Abstract: A radial press is provided having a first and a second ring structure which extend around a press axis and a plurality of pressing elements, which are disposed around the press axis and are translatably supported on supporting surfaces associated with the ring structures. The axial distance of the two ring structures from each other can be changed using a hydraulic drive system, which has a plurality of hydraulic cylinder-piston units oriented parallel to and distributed around the press axis, the cylinder of each cylinder-piston unit being coupled to a first of the two ring structures and the piston rod of each cylinder-piston unit being coupled to the second ring structure. At least the supporting surfaces associated with one of the two ring structures are oriented at an inclination with respect to the press axis. An electromechanical rapid adjustment drive comprising a plurality of adjusters is also provided.

  • Publication number: 20230114893
    Abstract: A radial press is provided having a first and a second ring structure extending about a press axis. Multiple press bodies are arranged about the press axis between the ring structures and are movably supported on support surfaces paired with the ring structures. The axial distance between the two ring structures can be changed using a drive system having a plurality of actuators oriented parallel to the press axis and distributed about the press axis. The support surfaces paired with one of the two ring structures are inclined relative to the press axis, and the press bodies are guided in a forced manner relative to the two ring structures in that the press bodies are equipped with guide grooves into which guide bodies engage.

  • Patent number: 11498299
    Abstract: A radial press has a plurality of press bodies arranged around a press axis which can be moved radially in relation to the press axis, and a drive unit for shifting the press bodies in the direction of or away from the press axis. The press bodies each have a main jaw and a pressing jaw, which is fixed interchangeably on the main jaw. The main jaws each comprise a radially inwardly arranged pressing-jaw-supporting surface and, adjacent to the latter in the circumferential direction, two side surfaces. The pressing jaws butt against the pressing-jaw-supporting surface of the associated main jaw and have a fixing protrusion, which projects from the abutment surface, enters into a mount provided on the main jaw and interacts with a locking device. Each main jaw has a recess on its supporting surface which extends from the mount and opens out on one of the side surfaces.
