Definitions

  • the invention relates to a press tool for connecting workpieces, with a press ring made of press jaw elements which are connected to one another in an articulated manner, the press tool being open at at least one closing point between two press jaw elements and having engagement points there for a closing device with which the press jaw elements can be brought together to form a closed ring.
  • sleeve-shaped press fittings which are plastically deformable and consist of metal, preferably of steel. Their inner diameter is so much larger than the outer diameter of the pipe ends to be connected that they are permanently deformed when they are pressed radially against the outer surface of the pipe ends.
  • Such pipe connections and the associated press fittings can be found, for example, in DE-C1 187 870 ⁇ and DE-C-40 ⁇ 12 50 ⁇ 4.
  • These pressing tools have a pressing ring which is open at a closing point and which is composed of pressing jaw elements which are connected to one another in an articulated manner and which in turn consist of a pressing jaw carrier and pressing jaws which are movably guided in the circumferential direction.
  • a press ring can be placed around the point to be pressed in a cuff-like manner and then pulled together with the aid of a closing device.
  • the locking device can be permanently connected to the press ring.
  • the compression ring is intended and dimensioned for the compression of larger pipe diameters, it is more advantageous for weight and handling reasons to design the locking device as a separate unit from the compression ring, which can be attached to the compression ring placed over the compression fitting in the area of the locking point, and in fact at points of attack provided for this purpose and adapted to the locking device on both pressing jaw elements adjacent to the locking point.
  • the area of application of such pressing tools is to be expanded to even larger pipe diameters.
  • the press ring then becomes so heavy that handling and safety problems arise when it is folded around the pipe end or around the press fitting.
  • the invention is therefore based on the object of designing a press tool of the type mentioned in such a way that the handling of the press tool is facilitated in particular when it is dimensioned for larger pipe diameters.
  • At least one coupling member is provided, with which the pressing jaw elements adjacent to the closing point (s) can be provisionally connected, the coupling member being designed to be flexible in the closing direction in the coupled state.
  • the press ring after it has been placed around the pipe end or the press fitting, can be provisionally secured by bridging the open closing point with the aid of a coupling member and thus closing the press ring.
  • the press ring can then no longer slip, and it is no longer necessary to hold the press ring in place for the closing device to be attached.
  • the coupling member is designed to be flexible in the closing direction according to the invention, while it limits the mobility of the pressing jaw elements in the opening direction.
  • the coupling member can be dimensioned such that the press ring can still be rotated around the workpiece.
  • the coupling member is dimensioned such that a circumferential force is applied to the pressing ring when it is placed around the workpiece and when the coupling member is closed, so that the pressing ring is pretensioned on the workpiece to be pressed , in particular the press fitting, is present, so that the press ring can at least no longer rotate automatically.
  • the coupling member can have a first coupling lug articulated to the one pressing jaw element and a second one to the other Compression jaw element connected coupling plate, wherein both coupling plates are articulated to each other, for example, via a coupling bolt encompassing both coupling plates.
  • a coupling member limits the mobility of the pressing jaw elements in the opening direction, but can articulate outwards during the pressing process with the aid of the closing device, without opposing the closing device in this case with any significant resistance.
  • the coupling bolt has a first bolt section which surrounds the first coupling plate and a second, in the second coupling tab has a graspable bolt section, the axes of the bolt sections being offset from one another.
  • the second bolt section thus forms an eccentric.
  • the length of the coupling tabs and the size of the offset of the axes of the bolt sections of the coupling bolt in relation to the circumferential extent of the locking point should be coordinated accordingly.
  • it is expediently connected to a lever.
  • the coupling pin should be captively guided in one of the coupling lugs.
  • the coupling straps are connected to the associated press jaw elements via hinge bolts and that recesses are provided in the region of the hinge bolts, can reach behind the locking elements of the locking device.
  • hinge pins simultaneously form the points of attack for the locking device.
  • At least one clamping device for contact with the inserted workpiece is attached to one side of the press ring, the clamping device (s) being able to have, for example, spring elements under spring tension.
  • the clamping devices are then in contact with the inserted workpiece, so that the workpiece that has been pushed over cannot slip off. This facilitates assembly, particularly in the case of vertical or inclined pipelines, and at the same time serves to axially secure the two workpieces which are plugged into one another.
  • the press tool according to the invention is not limited to the formation of the press ring with only one open closed position.
  • the pressing tool is intended for the pressing of large pipe diameters and is dimensioned accordingly in order to adapt it, it can be advantageous if the pressing ring has more than one closing point and a coupling member designed according to the invention is provided for each closing point.
  • This training enables the compression ring to be made from individual elements only on site, i.e. in the area of the pipe ends to be connected or even when the compression ring is folded around the pipe end one after the other. It is not excluded to provide a closing point that can be bridged with a coupling member even between all the pressing jaw elements.
