Definitions

  • the invention relates to a tool having at least two tool parts which are movable relative to one another according to the preamble of claim 1.
  • the pressing jaws which form the tool parts are placed around a workpiece to be pressed radially.
  • the press jaws initially have a distance from each other.
  • the pressing jaws approach each other until they lie against one another with their end faces and form a closed pressing jaw ring.
  • At least two of the pressing jaws are in this case displaceable in the circumferential direction relative to the pressing jaw carriers and guided on one of the pressing jaw carriers. This is to ensure that the pressing jaws are reliably adjusted in the closed mold in which they form the closed pressing jaw ring.
  • the leadership of the pressing jaws on the pressing jaw carrier and their displaceability along the associated pressing jaw carrier requires an accurate and therefore complex production of the corresponding tool.
  • the invention is based on the object, the generic tool in such a way that with him a reliable work is guaranteed. This object is achieved in the generic tool according to the invention with the characterizing features of claim 1.
  • the articulated connection between the mutually movable tool parts is formed by the hollow bolt, which is provided on the inside with a catching device. It ensures that when breaking the joint connection, the tool parts connected by them can not be separated from each other. As a result, there is no danger to the operator of the tool in the event of a break.
  • the press tool designed as a press ring, pipes and fittings can be radially compressed, in particular if they have a larger diameter.
  • the pressing ring 1 is shown in a position in which its pressing jaws 40 to 42 rest on the not yet radially compressed workpiece. It is not shown in the drawings for clarity.
  • the press ring 1 has a carrier 2, which is designed as a bracket, at the free ends of each of which a lever 3, 4 is arranged.
  • the levers 3, 4 form the pressing jaw carriers for the pressing jaws 41, 42.
  • the two levers 3, 4 are of the same design and are connected in each case via an axis 5, 6 pivotally connected to the free ends of the pressing jaw carrier 2.
  • the two axes 5, 6 are parallel to each other.
  • the pressing jaw carrier 2 extends over an angular range of about 180 °. At both ends of the pressing jaw carrier 2 with a central recess 12 ( Fig. 4 ), in which the pressing jaw carriers 3, 4 each engage with a narrow projection 13, 14.

  • the projections 13, 14 may be formed so that they do not protrude beyond the curved outer side 19 of the pressing jaw carrier 2 in each pivotal position of the pressing jaw carrier 3, 4.
  • the free ends of the projections 13, 14 are advantageously rounded and arranged in the recesses 12 so that the pressing jaw carrier 3, 4 can easily pivot relative to the pressing jaw carrier 2.
  • the pressing jaw carrier 2 is widened in the region of the recesses 12. In this area has the press jaw carrier 2 have the same thickness as the pressing jaw carriers 3, 4. These thickened end regions of the pressing jaw carrier 2 are connected to one another by a connecting piece 20, which has the same thickness as the widened end regions.
  • the connecting piece 20 is approximately V-shaped ( Fig. 1 and 2 ) and is surmounted by a narrow web 21 extending between the widened ends.
  • the pressing jaw carriers 3, 4 each have planar side surfaces 22, 23; 24, 25 ( Fig. 1 ), which lie in the same plane as the side surfaces 8, 9 of the connecting piece 20.
  • the mutually facing end faces 26, 27 of the pressing jaw carrier 3, 4 are flat. During pressing, the pressing jaw carrier 3, 4 can be pivoted against each other so far that their flat end faces 26, 27 have only a small distance from each other.

Since the pressing jaws 41, 42 are spaced from the pressing jaw carrier 2, it does not contribute to the guidance of the pressing jaws 41, 42, but instead the projections 70, 71 in cooperation with the depressions 68, 69. The pressing jaws 40 to 42 are thus moved relative to one another they abut one another with their end faces, so that the pressing contours 43 to 45 form a closed surface. The workpiece is radially compressed over its entire circumference, wherein a burr formation on the workpiece is reliably prevented.
  • the axes 5, 6, with which the pressing jaw carrier 3, 4 are hinged to the pressing jaw carrier 2, are designed so that when breaking these axes, the pressing ring parts can not be separated from each other. This is achieved in that the axles 5, 6 are provided with a catching device which holds the two tool parts connected to one another by the axles 5 or 6 in such a way that there is no danger of accident or injury to the operator.
  • Fig. 5 to 8 the one axis 5 is explained in more detail.

  • the connecting element 74 is advantageously a screw, but may also be a rivet, a bolt, a split pin, a pin and the like.
  • the connecting element 74 will be described in its construction as a screw.
  • the screw 74 is screwed with its free end into a threaded hole 75 in the cover 76.
  • the screw head 77 is sunk in a recess 78 in the other lid 79.
  • the two covers 76, 79 are held.
  • the screw 74 is in the area between the two covers 76, 79 surrounded by a catching device, which is preferably formed by a hose 80 which consists of a tear or shear-resistant material.
  • the hose 80 is advantageously against the inner wall of the hollow bolt 72 and surrounds the screw 74 at a distance.
  • the hose 80 is advantageously a metal fabric hose, but may also consist of correspondingly tear / shear-resistant plastic or, for example, a textile fabric.
  • a solid plastic bolt can be used, are embedded in the long glass fibers.
  • the catching device ensures that the tool parts connected to one another with the axle 5 can not be released from one another in the event of a breakage of the axle.
  • the screw 74 holds the tool parts connected to one another by the axis 5, in the exemplary embodiment the pressing jaw supports 2 and 3, together.
  • the tool parts 2, 3 interconnected by the axis 5 only move relatively little relative to one another.
  • the craftsman working with the tool, in the exemplary embodiment with the press ring 1 will often not notice the breakage of the hollow bolt 72 and continue to work with the press ring 1.
  • the screw 74 can not absorb the forces occurring during the subsequent pressing process and breaks. As it turned out Fig. 9 results, then the tool parts 2, 3 are shifted by a greater distance from each other.
  • Fig. 9 is shown schematically how the tube material is drawn in between these side surfaces.
  • the clamping force generated by the retracted tube material is so large that the two pressing jaw carrier 2, 3 do not separate from each other. Since the offset of the two die carrier 2, 3 is clearly visible due to the large displacement path, the worker working with the press ring 1 reliably detects the broken axis 5.
  • the tube 80 is preferably made of metal fabric which has a high tear / shear strength, it is ensured that the tube 80 is not severed, but reliably fulfills its clamping effect.
  • the metal fabric hose is a low-cost component that can also be very easily installed in the press ring 1. After a break, the axle 5 can be easily removed and replaced by a new axle.

  • the axis 6 of the pressing ring 1 is formed in the same way, so that even with a fracture of the axis 6 prevents the pressing jaw carrier 2, 4 from each other. Also in this case, a part of the tube 80 is pulled between the abutting surfaces of the pressing jaw carrier 2, 4 and jammed there. The resulting frictional force is so great that the two pressing jaw carriers 2, 4 can not be released from each other.
  • the predetermined breaking points 73 of the hollow bolt 72 are as Fig. 4 shows, in the amount of adjacent side surfaces 15, 16; 17, 18 provided the corresponding pressing jaw carrier. As a result, the break occurs at a defined point of the hollow bolt 72. Since these predetermined breaking points 73 in height of the adjacent side surfaces 15, 16; 17, 18 are provided, the tube 80 is reliably pulled in the described case of failure between these adjacent side surfaces when the die holders 2, 3 and 2, 4 move relative to each other due to the axis break.
