  • Patent number: 11724461
    Abstract: The invention relates to a system for producing a sealed connection of a press connector to a workpiece, in particular to a pipe, preferably to a plastic pipe, with a pressing tool for pressing a press connector and with a pressure tool for driving the pressing tool. The pressure tool is arranged to output a hydraulic pressure at a pressure generation point The pressing tool is arranged to receive a hydraulic pressure at a pressing location and to press a press connector accordingly. The pressure tool and the pressing tool are connected via a hydraulic pressure transmission connection, the pressure generation location and the pressing location being remote from each other. A corresponding method for producing a tight connection of a press connector to a workpiece, in particular to a pipe made of a flexible material, preferably a plastic pipe, as well as a press force translator and a press tool are also described.

  • Patent number: 11325178
    Abstract: A pressing tool for pressing fittings to produce pipe connections, with two opposing pressing jaws, each having a pressing section and a lever section, and having a retaining element for swivel connecting the pressing jaws, wherein the pressing sections form a receiving section and wherein pressing the lever sections apart causes the receiving section to close. An actuator spindle, a spindle nut and at least two actuator levers are provided, and each actuator lever is swivel connected at one end to the lever section of a pressing jaw and each actuator lever is swivel connected at another end to the spindle nut. A method for pressing fittings for the production of pipe connections is also disclosed.

The technical problem of pressing fittings to produce pipe connections in a simple and cost-effective manner is solved by the fact that an actuator spindle, a spindle nut and at least two actuator levers are provided, that each actuator lever is swivel connected at one end to the lever section of a pressing jaw and that each actuator lever is swivel connected at another end to the spindle nut. The invention also relates to a method for pressing fittings for the production of pipe connections.
