  • Patent number: 11648651
    Abstract: The installation tool for a wire thread insert includes: a drive unit which provides a switchable rotation movement between a first and a second direction, a mandrel body with a drive section for rotating the mandrel body and with a drive section for rotating the mandrel body and with a thread section onto which the wire thread insert can be screwed or rotated on, an installation blade as well as a torque clutch consisting of a form-fit and force-fit clutch upper and lower parts engaging each other, of which the upper part is connected with the drive unit in a torque-proof manner and the lower part is connected with the mandrel body in a torque-proof manner. With a decoupled relative rotation between the clutch parts, caused by exceeding a limit torque between the clutch parts, relative movement between the mandrel body and the installation blade can be generated.

  • Patent number: 11345004
    Abstract: The disclosure relates to a tool for inserting or removing a wire thread insert. The spindle body inserted in the tool has a radial recess, through which an engaging end of the installation blade engages a wire thread insert. The radial recess has a curvilinear circumferential contour or at least one relief notch, which serve for mechanical tension relief in the spindle body.

  • Patent number: 10883527
    Abstract: A wire thread insert comprises besides a cylindrical helix consisting of a plurality of coils a moving tang projecting into the interior of the helix for installing the wire thread insert into a receiving thread. The wire thread insert is connected to the cylindrical helix via a bending portion such that the moving tang can be redressed into the receiving thread after installation of the wire thread insert. The wire thread insert is installed by means of an installation tool with a mounting spindle, which installs the wire thread insert in the receiving thread via a moving shoulder and the moving tang. A compression blade provided at the mounting spindle bends the moving tang back into the receiving thread while the mounting spindle is removed from the installed wire thread insert.

  • Patent number: 10773365
    Abstract: The inventive installation tools are adapted to a wire thread insert comprising a cylindrical coil with a plurality of helically wound windings of a wire and a driving tang with a moving notch protruding into an interior of the coil via a bending portion. The installation tool has the following features: a rotatable mounting spindle with a driving end for rotating the installation spindle and a functional end for installing the wire thread insert, wherein the functional end comprises at least one turn that is length-reduced in the circumferential direction and that has, at a first end, a driving edge for engagement into a moving notch of the wire thread insert and, at a second end, a bend-up-shoulder for bending the driving tang of the wire thread insert radially outwardly.

  • Patent number: 10632523
    Abstract: A self-piercing riveting die for a setting device, by which a self-piercing riveting connection in a plurality of components is establishable by forming a closing head. This self-piercing riveting die may include a main body with an upper side and a recess arranged rotationally symmetrically to the central axis of the self-piercing riveting die formed therein. In the cross-section of the self-piercing riveting die, the recess has a demolding inclination of the demolding section, which radially transitions via a step into a circular arc-shaped lowering of the annular channel section, wherein the circular arc-shaped lowering radially inwardly rises straight-lined or circular arc-shaped or curvilinearally to the die bottom.
