Definitions

  • the invention relates to a device for applying a compressive force according to the preamble of claim 1.
  • axial pressing technique it is known to use a press fitting of support sleeve and pressure sleeve.
  • the one pipe is first expanded before the press fitting can be inserted into the expanded pipe end.
  • This additional expansion process is complicated and means an additional step.
  • the pressure sleeve is pressed by means of the device axially to the stop on the fitting.
  • a pressing ring and a crimping ring are pushed over the tube.
  • a support sleeve (fitting) is inserted into the pipe and the press ring with the aid of the device is pressed axially over the crimp ring to the stop on the support sleeve.
  • a prior expansion of the tube is not necessary.
  • a manually operated pressing device which is designed similar to a pair of pliers. It has actuating arms that are reciprocated back and forth against each other during the axial pressing operation, wherein a pressing member is moved in the direction of the other pressing member via a chain or a ratchet. Also, this device has large dimensions and is unwieldy to use.
  • a pressing member is provided on a sliding sleeve which is movable on a pipe piece in the direction of the other pressing member by means of hydraulic medium.

From this further piece of pipe is perpendicular from a handle with which this device can be held.
  • the device can only carry awkward, since the handle at one end and the pipe support piece for the pressing parts are arranged at the other end of the tube. It is therefore considerable effort necessary to hold the device during the pressing process.
  • Further pressing devices are designed as sliding tongs, in which pressing parts again perform a pivoting movement, which leads to problems with straight tubes.
  • the invention has the object of providing the generic device in such a way that with a structurally simple design and ease of handling a perfect compression is guaranteed.
  • the device is designed as a portable tool that can be comfortably carried by the operator.
  • the device has a housing 1, which advantageously consists of two detachably interconnected housing shells.

The opposite, acted upon by the hydraulic medium piston surface 75 in this position still distance from the bottom 76 of the cylinder chamber 49. This ensures that the hydraulic medium can reach the piston surface 75 even with fully retracted piston 50.
  • the projection 69 of the carriage 59 extends, as shown in FIG. 3, only over a part of the height of the housing 51.
  • Fig. 3 shows the initial position of the pressing member 39, in which it has the greatest distance from the opposite pressing member 53, the difference to the pressing member 39 rigid, preferably integrally formed with the piston housing 51.
