Definitions

  • the invention relates to a pressing tool and a method for radial pressing of workpieces, in particular of pipes and / or press fittings on pipes.
  • a pressing tool which has a pressing sling made of pressing elements coupled to one another in hinge joints, with pressing jaws being movably mounted on the inside of the pressing elements.
  • the press jaws By pulling the press sling together, the press jaws are moved radially inward and thus cause a corresponding pressing of a pipe around which the tool is wrapped.
  • Advantageous refinements are contained in the subclaims.
  • the pressing tool is further characterized in that the ring contains a partial ring which consists of one or more ring segments which are coupled to one another to transmit tensile force, one end of the partial ring also being coupled to the first tensile force transmitting jaw.
  • the partial ring is also referred to below as the “first partial ring”.
  • the pressing tool contains a second partial ring made of ring segments coupled to transmit tensile force.
  • a tensile force-transmitting chain is produced via the first partial ring from a first end of the partial ring to the tension press jaw.
  • one of the above-mentioned coupling points is arranged at the first end of the partial ring, via which a tensile force causing the ring to close is introduced into the entire ring.
  • Such a tensile force can be generated, for example, by an external tool (so-called “pressing tongs”).
  • pressing tongs an external tool
  • the tensile force for closing the ring is not transferred in a closed circle from one ring segment to the next, but via the partial ring directly to the tension pressing jaw. In practice it turns out that in this way the pressing forces to be applied can be reduced and that a better pressing result can be achieved through a uniform radial inward movement of the pressing jaws.
  • a general device should preferably be viewed as "tensile force-transmitting" if it has a first point for the application of a (tensile) force and a second point for the transmission of the (possibly according to size and / or direction converted) tensile force, a (small) movement of the first point in the direction of the tensile force inevitably entails a corresponding movement of the second point.
  • the (tensile) force introduced at the first point can always be compensated for by a suitable counter (tensile) force introduced at the second point, so that the first point (initially) does not move in the direction of the (tensile) introduced Power moves.
  • two elements e.g. two ring segments or one ring segment and the tension-pressing jaw
  • two elements can be described as "coupled in a manner that transmits tensile force” if the tensile force (initially) does not result in any relative displacement between the elements (at most a rolling motion).
  • Transmission of tensile force is, for example, a tensioned chain or a tensioned wire rope (but not a rolled up, loose chain with play in the chain links).
  • a "tensile force” can also be defined in that it runs essentially tangentially with respect to the center point of a workpiece to be machined (or, in other words, perpendicular to the local direction of the pressing force).
  • Other forces acting on the ring segments and / or press jaws, on the other hand, are typically essentially radial with respect to the center of the workpiece.
  • the invention further relates to a corresponding method for the radial pressing of workpieces, wherein the method can be carried out in particular with a pressing tool of the type described above.
  • the method comprises the introduction of a tensile force in coupling points of a ring made of ring segments in order to effect the closing (circumference reduction) of the ring, said tensile force being transmitted via a first partial ring made of tensile force-transmitting ring segments to a first tension press jaw, which is movably attached to is mounted on a ring segment.
  • the first tension press jaw is usually mounted on a ring segment that does not belong to the first partial ring.
  • the transmission of the tensile force can be continued via the connection of the tension press jaw to the ring segment that carries it.
  • a second partial ring made of (one or more) tensile force-transmitting ring segments, one end of which is tensile force-transmitting coupled to a second tensile pressing jaw, which is movably mounted on a ring segment (preferably on its inside) .
  • the ring segments that make up the second partial ring are typically different from those of the first partial ring.
  • the first and the second tension press jaws are usually mounted differently and also on different ring segments.
  • all ring segments of the pressing tool are either part of the first partial ring or of the second partial ring.
  • the first and the second partial ring can be constructed structurally different, z. B. by consisting of different numbers of ring segments.
  • the second partial ring is constructed essentially symmetrically to the first partial ring.
  • the "symmetry" can be on an abstract, functional level (i.e. both partial rings contain corresponding numbers of ring segments with correspondingly arranged press jaws).
  • the symmetry can also be geometric in the narrower sense (in particular as a mirror symmetry to a center plane). On the one hand, the symmetry achieves a more uniform effect of the tool.
  • the production costs can be reduced by using identical or symmetrical components.
  • the first tension-pressing jaw is preferably movably supported on a terminal (proximal) ring segment of the second partial ring.
  • the first tension-pressing jaw thus represents a connection between the ring segments of the first and the second partial ring.
  • the second tension-pressing jaw can additionally or alternatively be mounted on an end ring segment of the first partial ring.
  • terminal ring segments of the first partial ring and the second partial ring can be coupled to one another via a link. This means that direct force transmissions between these ring segments and thus between the partial rings are possible, although certain directions of force are excluded from the transmission due to the mobility corresponding to the link (since there is freedom of movement in these directions). Typically, these are directions primarily pointing in the circumferential direction, in which tensile force would be transmitted.
  • At least two ring segments of the pressing tool can optionally be coupled to one another via a hinge joint (swivel joint). All ring segments that belong to the first partial ring (and / or all of the ring segments that belong to the second partial ring) are preferably coupled to one another via a hinge joint. A tensile force can be transmitted in full via a hinge joint.
  • first partial ring can be coupled in a hinge joint (swivel joint) to the first pull-press jaw (and / or the second partial ring to the second pull-press jaw).
  • hinge joint pivot joint
  • second partial ring to the second pull-press jaw
  • the first partial ring can be coupled to the first tension / press jaw in a joint that allows a rolling and / or sliding movement perpendicular to the respective direction of the tensile force acting there (and / or, analogously, the second partial ring to the second train Press jaw).
  • the freedom of movement gained in this way can be used to enable a uniform, radially inward migration of the pull-press jaw.
  • At least one press jaw is movably arranged on each ring segment (preferably on the respective inner sides).
  • the mobility of at least one press jaw (including the tension press jaw (s)) with respect to the associated ring segment can in particular be a displacement movement in the circumferential direction (in relation to a circular workpiece to be machined). Due to the mobility of the pressing jaws, they can adjust themselves on a workpiece independently of the ring segments and, in particular, ensure uniform pressing by maintaining uniform distances from one another.
  • the movable pressing jaws of the pressing tool are preferably mounted in such a way that they have or maintain essentially the same distance from one another before and / or during a pressing process (ie the same size gaps in the circumferential direction).
  • This is usually synonymous so that each individual press jaw moves in a straight line radially inwards towards the center of the workpiece to be pressed. Since the movement of the pressing jaws during a pressing process usually also depends on the workpiece being processed, e.g. on the surface properties of a fitting, the above condition ideally relates to the case of a workpiece that is the same for all pressing jaws, in particular a workpiece with a surface made of stainless steel.
  • the pressing jaws of the pressing tool can in particular be mounted on a circumferential sliding surface (which is usually located on an associated ring segment) so that they can move (only) in the circumferential direction (relative to the ring segment).
  • the movement of the pressing jaws of the pressing tool can be limited to a specific area by at least one stop and / or a guide link.
  • At least one spring element can additionally or alternatively be present, which presses a movable press jaw of the press tool in a predetermined direction.
  • the spring element can preferably press the press jaw against a stop into a predefined position before the start of a pressing process, if the press jaw is not yet influenced by the friction with the workpiece. This position can be distinguished in particular by the fact that all press jaws are at the same distance from one another.
  • the pressing tool contains a holding device by means of which a first ring segment can be held (stabilized) at at least one defined angle with respect to an adjoining second ring segment.
  • the holding device is preferably designed to hold the ring segments alternatively at two defined angular positions.
  • the held angular positions can in particular include an open position in which the ring of the pressing tool is open and can thus be placed around a workpiece. Furthermore, a The closed position is held, which is assumed when the pressing tool has been placed around a work piece (loosely).
  • the aforementioned holding device can be implemented in various ways. It can, for example, comprise a spring-loaded pin which is mounted on a ring segment and against which a cam of an adjacent ring segment presses. The positions of the cam “left” and “right” of the pin can be stabilized in this way.
  • the introduction of a tensile force into the ring of the pressing tool is possible in various ways.
  • the coupling points can be set up in this regard for the attachment of locking pliers, the jaws of the locking pliers being able to pull the ends of the ring together with the introduction of tensile forces.
  • the embodiments of pressing tools described below are used for the radial pressing of workpieces such as, for example, fittings on pipes or pipe connections.
  • Figure 1 shows in this regard schematically a pressing tool 1 which is designed according to the present invention.
  • the tool 1 has several (in the example shown four) pressing jaws 11, 12, 11 ', 12' which can be arranged around a workpiece (not shown) to be machined and come into direct contact with it during the pressing process.
  • a ring 20, 20 ' (also called a press chain or press sling) which loops around the outside of the press jaws and two at its ends Has coupling points K, K 'at which a tensile force F, F' can be introduced (for example by means of pressing tongs according to FIG Figure 19, 20 ).
  • the ring is designed in such a way that it can continuously transmit tensile force from one coupling point K to the other (K '), for example by consisting of segments which are all connected to one another via swivel joints.
  • the tensile force is passed on and deflected along the ring 20, 20 '. It runs essentially in the circumferential direction at every location, i.e. tangentially in relation to the center of the workpiece to be machined.
  • a first partial ring 20 is provided in the ring, which runs from a first coupling point K to a point of application R on a pressing jaw 12 ', which is referred to below as the “first tension-pressing jaw”.
  • the in Figure 1 The first partial ring 20, indicated only schematically as a line, typically consists of ring segments that are rotatably coupled to one another.
  • the tensile force F introduced at the coupling point K is passed on (and deflected) along the first partial ring 20 and finally transmitted to the first tensile pressing jaw 12 ′ at the point of application R.
  • a tensile force is not completely closed around everyone Press jaws passed around, but only partially passed around some press jaws and directly introduced into another press jaw (the "pull-press jaw").
  • This (pull) press jaw is typically mounted on a ring segment that does not belong to the pulling partial ring 20. It has been shown that a more uniform pressing can be achieved in this way, in which, in addition, lower frictional forces occur.
  • FIG. 1 There is also a second partial ring 20 ', which is functionally and geometrically mirror-inverted to the first partial ring 20 (ie that it runs from the second coupling point K' to a second "pull-press jaw" 12, to which it pulls -transferring coupled).
  • the first press-pull jaw 12 ' is mounted on the inside of the second partial ring 20' (typically it is movably mounted on one of the ring segments of the second partial ring 20 '), while the second press-pull jaw 12 is on the inside of the first partial ring 20 ( typically also displaceable on one of the ring segments of the first partial ring 20).
  • This causes the two partial rings 20, 20 'to overlap or interleave.
  • the first tension press jaw 12 ' on which a tensile force is exerted by the first partial ring 20, is pressed radially inward by the second partial ring 20' (and thus prevented from simply yielding to the tensile force).
  • the second tension press jaw 12 is pressed radially inward by the first partial ring 20 and is thus held in place.
  • the entanglement of the partial rings 20, 20 'thus prevents the pressing tool from falling apart.
  • FIG. 2 to 18 shows a pressing tool 100 according to a specific embodiment of the principle generally explained above.
  • the Figures 2-4 show different views of the pressing tool 100 in its open position, in which it can be placed around a pipe (not shown) or the like.
  • the pressing tool 100 contains a first partial ring 120 with a distal ring segment 121 and a proximal ring segment 122, which are coupled to one another by a hinge joint G1. Furthermore, the first partial ring 120 contains on its terminal, distal ring segment 121 a coupling point K (e.g. a bolt) on which a jaw of a pressing tong ( Figures 19, 20 ) can attack and initiate a tensile force. Press jaws 111, 112 are each mounted on the inner sides of the ring segments 121, 122 in a displaceable manner.
  • K e.g. a bolt
  • the pressing tool 100 also contains a second partial ring 120 ′, which is constructed in a mirror image of the first partial ring 120, with corresponding parts having the same reference numerals provided with dashes.
  • proximal ring segment 122 'of the second partial ring 120' couples tensile force-transmitting via a joint G2 to the second tension press jaw 112 (which in turn is movably mounted on the proximal ring segment 122 of the first partial ring 120).
  • FIG. 4 rather shows that, for example, a bolt connected to the proximal ring segment 122 of the first partial ring 120 in the joint G2 'engages through an elongated hole L' of the proximal ring segment 122 'of the second partial ring 120', the size and orientation of the elongated hole L 'being such that During a typical pressing process, no direct force transmission takes place between the two partial rings 120, 120 '(at least no force transmission with a substantial tangential component in the circumferential direction).
  • FIG 4 two holding devices can also be seen, via which a distal ring segment 121 (or 121 ') in relation to the adjacent proximal ring segment 122 (or 122') in the open position ( Figure 4 ) or in a closed position ( Figure 9 ) is kept stable.
  • the holding devices are each formed symmetrically on the first partial ring 120 and second partial ring 120 '.
  • the holding device on the first partial ring 120 consists essentially of a spring pin 125 which is mounted in a bore in the proximal ring segment 122 and is pressed outwardly out of the bore by the force of a spring (not shown).
  • the spring pin 125 presses with its round head against a protruding cam or nose of the distal ring segment 121 and is thus retained in the bore.
  • its pressure stabilizes the open position or the closed position of the distal ring segment 121.
  • One and the same mechanism is thus used to lock two different working positions of the pressing tool 100 (reversible), which accordingly facilitates the use of the tool.
  • the pressing tool 100 is shown in a loosely closed position which it assumes after it has been placed around a workpiece that has not yet been pressed.
  • the construction of the tool is such that between the four pressing jaws 111, 112, 111 ', 112' there are as large as possible the same distances ⁇ . This is achieved, inter alia, in that the pressing jaws 111, 112 or 111 ', 112' are pressed by springs (not shown) in the direction of the coupling points K and K '.
  • the second tension press jaw 112 can be coupled to the bolt via elongated holes or expanded round holes 112b, which forms the joint G2 and which is rotatably coupled to the proximal ring segment 122 'in a round hole (cf. Figure 4 ).
  • the shape of the hole 112b is chosen so that the bolt of the joint G2 is essentially always perpendicular to the edge of the hole during the pressing process and can thus transmit tensile force without a relative displacement movement between the tension press jaw 112 and the ring segment 122 ' while at the same time one for geometric reasons necessary migration of the bolt in hole 112b is possible.
  • the bolt is then at the other end of the elongated hole 112b (cf. Figure 11 ).
  • a similar effect could also be achieved by a round hole on the tension press jaw 112 in conjunction with an elongated hole on the ring segment 122 'and / or by a non-round bolt.
  • An analogous structure is also present for the joint between the first tension press jaw 112 ′ and the ring segment 122.
  • the direction of pressure of the springs mentioned above is indicated by arrows.
  • the pressing jaws have links 111a, 112a through which a pin of the associated ring segment 121 or 122 engages. This creates a stop which stops the further movement of the pressing jaws in the direction of the arrow and ensures that the even distances ⁇ are present at the start of the pressing process.
  • the pressing jaws move along circumferential sliding surfaces that are formed on the associated ring segments. As explained, this movement is preferably such that the distances ⁇ between the pressing jaws always remain the same. This is achieved not least by a suitable shape of the elongated holes L, L 'in the proximal ring segments 122, 122', by means of which the possibilities of movement of these ring segments are also determined.
