Definitions

  • the invention relates to a pressing tool according to the preamble of claim 1, a pressing ring according to claim 7, a pressing tongs according to claim 8, as well as a pressing tool according to the preamble of claim 9, a pressing ring according to claim 15 and a pressing tongs according to claim 16.
  • Known press tools for permanent connection by pressing of workpieces are generally composed of two tool units - a first and a second press component.
  • the first pressing component is designed as a press ring, press jaw or press sling, etc. - hereinafter referred to press ring - formed, generally with mutually pivotable jaws, the second pressing component as a press device for pressing the press ring - hereinafter referred to as pressing tongs.
  • pressing tongs With the crimping pliers, the pressing ring or its jaws, which is attached as conclusively as possible to the workpieces to be joined, is compressed so that the workpieces are pressed together in such a way that a permanent connection is created.
  • the press ring usually has two or more hingedly connected jaws, wherein two jaws are not connected, but form a closing point. At the two jaws forming the closing point, the pressing tongs are applied and applied to the jaws by pressing the same pressing force.
  • the EP 1 201 371 describes a pressing tool with a forceps-like pressing jaw, which is pivotable with respect to the plane of a pressing sling.
  • Pressing jaw and sling are articulated by means of coupling means in that the pressing jaw has part-spherical cams and the pressing sling has partly spherical dome in which the cams can be inserted and articulated.
  • the press loop with the cams as a coupling means is manufactured as a one-piece casting, as well as the pressing jaw with the dome as a coupling agent. This is in case of wear, which have an insufficient compression result, the replacement of an entire pressing component - press loop / press jaw - or a new tool required.
  • the die is movable only relative to the plane of the press loop. An advantage would be a tool with even more degrees of freedom of movement.
  • Another object is to provide the pressing components pressing ring and pressing tongs of the pressing tool, which allow a movement with more degrees of freedom of movement than known pressing tools.
  • a pressing tool for non-detachably connecting, in particular tubular, workpieces by, in particular radial, compression, associated with a press ring and a pressing tongs as pressing components of the pressing tool engagement modules by means of which pressing ring and pressing tongs of the tool are coupled such that a relative movement between crimping pliers and engagement modules - and thus indirectly between pressing tongs and press ring - is made possible.
  • the pressing tool can be designed so that the relative movement between the pressing ring and engagement modules takes place.
  • intervention modules are mounted in the forceps arms of the pressing tongs or in the press jaws of the press ring medium or immediately movable.
  • the invention is described in the embodiment with the movable in the forceps arms of the pressing tongs engagement modules. It should be noted, however, that the embodiment can also be carried out in the press jaws of the press ring movably mounted engagement modules.
  • pliers arm can be replaced by press jaw and crimping pliers by press ring (or pressing jaw by pliers arm and pressing ring by crimping pliers) in the further description.
  • the pressing tool is essentially formed from a first and second pressing component, wherein the first pressing component is referred to as a pressing ring and the second pressing component as pressing tongs. It is understood, however, that Other common names, such as press jaw, press loop, etc., can be used for the first and second pressing component.
  • the pressing ring is preferably composed of a plurality of pivotally interconnected pressing jaw elements, wherein two jaws are not connected, but form a closing point. If all the pressing jaws are "pivoted in”, then the pressing jaws form a substantially circular receptacle for workpieces to be machined, such as pipes.
  • the press ring can be designed with only two jaws, for larger diameters usually three or more press jaws are required. For non-tubular workpieces a press ring is designed accordingly differently.
  • the press ring is laid around workpieces to be pressed, such as pipes or pressfitting systems, or are inserted into the press ring, in particular for smaller diameters, fittings, the press jaws then largely closed and contracted.
  • the pressing tongs To contraction of the press ring - and thus the application of pressing force on the workpieces to be joined - the pressing tongs is provided.
  • the required - high - pressing pressure is achieved via a mechanical or electro-mechanical drive in a known manner. Due to the radial or axial compression of the workpieces, they are plastically deformed, resulting in a permanent connection. Important for a perfect pressing is a complete closure of the press ring.
  • press ring and tongs are coupled together.
  • the pressing tongs has two forceps or lever-like devices, which are referred to as pliers arms. These pliers arms are attached to the press jaws defining the closing point.
  • the pliers arms are “pulled apart” and thus the pressing jaws compressed so far that they are closed at the closing point and creates a closed system.
  • the coupling of pressing ring and pressing tongs is crucial for achieving this closed system. In case of faulty coupling - due to wear, for example - the pressing ring can no longer be completely closed and the pressing is therefore insufficient.
  • the coupling of gripper arms and pressing jaws takes place via engagement modules, which are attached to engagement regions of the pressing jaws and associated with the gripper arms in such a way that gripper arms and engagement modules are spatially movable relative to one another.
  • a movable mounting of the engagement modules in the gun arms makes it possible to relocate the required for pressing movement between the pressing jaws and gun arms in the gun arms.
  • An engagement module may be formed as a ball and be articulated in a ball bearing receptacle in the gun arms. If the ball is flattened on its side facing away from the receptacle, so to speak "beheaded", then the flat side becomes a flat surface with a larger contact surface provided in comparison to a spherical surface with a punctiform bearing surface.
  • the engagement module is attached to the engagement region of the pressing jaw, the engagement region - or the support surface - can either be designed so that attached engagement module and press jaw rigidly against each other, or with a certain margin for a shift.
  • the ball is also used in an intermediate member and the intermediate member in the gun arm.
  • the intermediate member is designed as a screw element receptacle
  • the pliers arm has a dowel-like receptacle
  • the flattened engagement module ball can be movably mounted in the screw element receptacle and the screw element can be screwed into the dowel-like receptacle.
  • the pliers arm is rotatable and pivotable relative to the engagement module. With the flat side, the engagement module can then be attached to the engagement region of the corresponding pressing jaw.
  • the engagement regions of the pressing jaws can be embodied as depressions or in other known embodiments. It is also conceivable to carry out the engagement as well as the respective bearing surfaces as rough, friction-coupling surfaces.
  • the tool is designed wear-friendly.
  • the engagement modules or engagement modules with pontics are easily replaceable.
  • the inventive coupling of pressing tongs and press ring is a wear-friendly and cost-effective method by worn Intervention modules are easily replaceable.
  • FIG. 1 shows a possible embodiment of a pressing tool 1 according to the invention with a pressing ring 2 as the first pressing tool 3 and a pressing component 3 as a second pressing component.
  • the pressing tongs 3 is shown in tilted to the plane of the compression ring 2 position.
  • the pressing tongs 3 is pivotable not only from the plane but also in the plane of the press ring 2 in a certain angular range. This possibility of turning and pivoting movement makes the tool a flexible and versatile, extremely handy device.
  • the press ring 2 of the tool comprises two articulated jaws, which form a substantially circular holder into which workpieces to be joined can be received. In the illustrated tool, the pressing ring 2 is not completely closed.
  • the first and second pressing jaws 2a, 2b are closable at their closing point S, and the workpieces clamped in the holder can be pressed.
  • the pliers arms 3a, 3b are coupled to the first and second pressing jaws 2a, 2b, which are hinged together on the one hand and, on the other hand, a closing point S, as engagement elements 6a, 6b integrated into intermediate links are provided as coupling elements.
  • the intermediate members are formed as screw 5a, in which the engagement modules 6a, 6b are movably mounted.
  • This combination which is also known as a clamping bolt 4a, 4b, is screwed as a coupling element on the one hand into a dowel-like receptacle of the tong arms 3a, 3b and on the other hand to an engagement area 5a of the press jaws 2a, 2b.
  • FIG. 2A shows the pressing ring 2 of the pressing tool 1 from FIG. 1.
  • the pressing ring 2 is formed from a first and a second pressing jaw 2a, 2b, which are connected via a joint G.
  • the pressing jaws can be opened or closed.
  • the pressing jaws are first swung out and placed around workpieces to be machined, and then pulled together by means of pressing tongs 3.
  • the pressing jaws each have an engagement region E for attaching the engagement modules 6a, 6b, in the embodiment shown a depression.
  • the engagement modules 6a, 6b bear with a circular support surface A against the engagement regions E.
  • FIG. 2B shows an engagement module 6a mounted in an intermediate element.
  • Intermediate member and engagement module 6a are formed as a unit in the form of a clamping bolt 4a.
  • Such clamping bolts 4a are available as standard parts.
  • the intermediate element designed as a screw element 5a can be screwed into dowel-like receptacles of the forceps arms 3a, 3b.
  • Such a clamping bolt 4a represents a cost-effective possibility for a replaceable coupling element.
  • a flattened in the upper third ball as engaging module 6a is in the screw 5a - so to speak as a module head - mounted so that a spatial movement of the ball in a certain angular range is possible.
  • FIG. 2C shows the engagement module 6a from FIG. 2B in an intermediate element designed as a plug-in element 5c, which can be coupled via a plug-in mechanism to a corresponding receptacle of a tong arm.
  • the pressing tongs 3 are shown as the second pressing component of the pressing tool 1 from FIG.
  • pressing tongs 3 pressing force is applied to the pressing jaws of the pressing ring 2 by a first and second gun arm near the closing point S to the first and second pressing jaws 2a, 2b and attached by an outward movement of the gun arms 3a, 3b the pressing jaws until closing the closing point S be squeezed.
  • the engagement modules 6a, 6b the forceps arms 3a, 3b are attached to the engagement regions E of the pressing jaws.
  • the pliers arms 3a, 3b have - not apparent from the figures - dowel-like receptacles for the screw 5a on, but can in other embodiments also with recordings for non-screw units, such as plug-in elements 5c, or for other intervention modules, e.g. be designed as a ball bearing, etc.
  • a movement of the pressing tongs 3 relative to the engagement modules 6a, 6b-which is indirectly via intermediate links- is made possible, which considerably simplifies the handling of the tool.
