  • Patent number: 12251902
    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: 12202027
    Abstract: A method is provided for joining structures, where at least one of the components to be joined is individually plastically deformed in a radial press. A control unit for the radial press has a PLC machine controller and a BTLE communication module and a mobile terminal is associated. Mobile terminals are designed to communicate with a central server via a mobile data network, which central server is equipped with a pressing program memory. Configuration programs used to set up associated radial presses are stored on the mobile terminals. Each radial press is set up by means of the associated mobile terminal, specifically by configuration of the PLC machine controller by means of a specific pressing program in accordance with program-specific data retrieved from the central server for a particular lot. Within the lot, each individual radial deformation process is triggered by triggering means arranged on the radial press itself.

  • Patent number: 12130208
    Abstract: When producing a high-pressure hydraulic line, a connection fitting is attached to a multi-layer high-pressure hose having a reinforcing layer. A portion of a reinforced high-pressure hose and a connection fitting to be joined to it are provided. The connection fitting is placed onto the end portion of the high-pressure hose and a joining operation is carried out to form a sealed connection. The quality of the connection is determined by applying an electrical test signal to at least one connection of a testing arrangement having two connections. A first connection is electrically and/or magnetically coupled to the connection fitting and a second connection is contactlessly electrically and/or magnetically coupled to a reinforcing layer of the high-pressure hose. An electrical response signal is detected and the response signal is compared with a setpoint-value range stored in a memory of the testing arrangement.

  • Patent number: 12013070
    Abstract: A hydraulic unit has a hydraulic component, a hydraulic line connected to a hydraulic connection of the hydraulic component, and a hose and fitting connected to the hydraulic connection. A tear-out preventer having a cable loop secured by a cable clamp acts on the hose. The cable clamp comprises a clamping block, which has two crossing passages and a rivet. A first passage, through which the cable is guided, has, in the region of the crossing with the second passage, a width corresponding to at least double the thickness of the cable plus the diameter of the non-deformed rivet. The second passage is configured in a stepped manner with a narrow primary portion arranged on one side of the first passage and a wide secondary portion arranged on the other side. The rivet braces the two strands of the cable against the inner wall of the first passage.

  • 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.

  • 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.

  • Patent number: 11052447
    Abstract: A radial press comprises a housing having a lateral portion and a supporting disk on the end face. A ring-like structure extends in the housing and can be displaced along a pressing axis. Multiple pressing jaws arranged around the axis are radially movably supported on the supporting disk. The ring-like structure acts upon the jaws with control faces angled relative to the axis and are seated against counter-faces of the jaws. The angle of the control faces changes as they progress in the axial direction, such that, along the maximum path of travel of the ring-like structure, the axial movement of said structure and the radial movement of the jaws produced thereby are at different ratios. The ring-like structure has exchangeable control elements on which control faces are provided. In planes perpendicular to the pressing axis, each control face is seated on a polygon having corners arranged between adjacent jaws.

  • Patent number: 10286620
    Abstract: A radial press is provided, the radial press having a frame structure, a pressing tool, a drive unit, and a press control. The pressing tool comprises a plurality of pressing elements which are disposed uniformly concentrically around a press axis and have pressing surfaces. During the appropriate activation of the drive unit, the pressing elements can be moved synchronously as required towards or away from the press axis. To this end, at least two measured value recorders, which are connected for signal transmission purposes to a comparator associated with the press control, are disposed on the pressing tool at positions spaced apart from one another in the direction of the press axis (A). When the comparative value, generated by the comparator, of the measured values provided by the measured value recorders exceeds a tolerance range stored in the press control, an activation of the signal output unit is triggered.
