  • Patent number: 6634202
    Abstract: A device for arranging, clamping or contracting a ring-shaped securing mechanism, including an open clamping ring (3) with a securing section (5, 7) at each end; and at least two ring-shaped clamping jaws (11) located inside the clamping ring. The clamping jaws rest against the clamping ring (12) with their outer edge (12) and together at least almost form a circular opening with their inner surface (19). The device also has at least one spring-type mechanism (15) being situated respectively between the laterally contiguous clamping jaws to drive them apart or to part the clamping ring in its non-clamped state, in the direction in which the ring opening diameter increases and to secure the clamping jaws in the clamping ring. The open clamping ring can be clamped in the direction in which the diameter decreases by means of a clamping mechanism with at least two engaging sections which are provide for engaging with the securing sections.

  • Patent number: 6058755
    Abstract: A press tool for non-detachably connecting through cold deformation a fitting and an end portion of a metal pipe received in a socket of the fitting, includes a wraparound ring for placement over the socket of the fitting, and a machine-operated clamping device. The wraparound ring includes a plurality of hinged links and is open at one closing area between two terminal links which are formed with pockets to form grip points for application of the clamping device. The clamping device has a pair of jaws which terminate in lobed ends for engagement in the pockets of the terminal links. The socket of the fitting has formed interiorly a receiving groove which opens inwardly for receiving at least one holding element which is formed with projections or cutting edges for penetrating the material of the metal pipe during radial cold deformation.

  • Patent number: 5598732
    Abstract: A compression tool includes a housing having adjacently disposed first and second oppositely disposed portions defining therebetween a clearance. First and second pivot levers are provided, and each of the levers is pivotally secured to one of the portions and extends therefrom beyond the housing. At least three compression jaws are operably associated with the housing and disposed about the clearance. One of the jaws is secured to the housing and the other two of the jaws are each connected to one of the levers and are pivotal therewith. The one jaw is separate from the first and second levers. Each of the jaws has an arcuate compression surface. A movement assembly is operably associated with each of the levers and the associated jaw for causing cooperating movement thereof. A drive assembly is operably associated with each of the levers and is disposed exteriorly of the housing for causing pivoting thereof between a first open position and a second closed position.

  • Patent number: 4362044
    Abstract: The invention contemplates a pipe-bending technique wherein an arcuate die which determines the course of bending the central axis of the pipe relies solely upon two tangentially engaging developing lines of contact which are spaced equally, at opposite offsets from the radial plane in which the pipe axis is bent. For the case of pipe bending to a circular arc, the opposed die faces are generally conical, and there is no pipe contact with the die in the range between the spaced developing lines of tangential contact.
