Definitions

  • the invention relates to a device for pressing connectors as part of a pipe joint according to the preamble of patent claim 1 and a method for pressing connectors as part of a pipe joint using such a device according to the preamble of claim 16.
  • the subject of the prior art pipe joints is that a sealing plug connection is made between a plug and a socket.
  • the plug forms an annular receiving space in which engages the front end of the hose, wherein the inner part of the plug is deformed with an attached from inside to the inner wall of the plug expansion tool such that a radially outwardly directed, ring encircling Verpressnut results, which reduces the hose diameter-reducing over the entire circumference in the annulus of the plug.
  • the hose is sealingly and firmly received by said press connection in the annular space of the plug.
  • the invention is therefore based on the object of developing a method and a device for pressing elastomeric tubes into plugs as part of a pipe connection in such a way that a secure and operative press connection between the plug and the elastomeric hose is produced, which is independent of wall thickness differences of the plug, the hose and the like.
  • hose is used broadly in the context of the present invention. It is understood not only an elastomeric hose, but also a tube, which also does not necessarily have to be elastomeric. It may therefore also be conventional plastic pipes in which it is also possible due to the material properties to deform the material such that a radially outward press bead engages in the inner part of the plug into the material of the tube.
  • the invention proposes a device and a method having the features of claims 1 and 16.
  • the technical teaching according to the invention also provides tightening torque monitoring of fastening screws, which fastening screws represent the connection between the actual expansion tool and the slanting sliders that attach to the expansion tool.
  • a significant advantage of a development of the invention lies in the fact that the Verpressnut is attached directed from the inner circumference of the plug to the outside. This results in the advantage that the spreading forces can be measured from radially inward to radially outward, which is a significant advantage over the prior art, in which the spreading forces could be detected (indirectly) only in the radial outer region of the plug.
  • the technical teaching according to the invention also provides the advantage that crack formation during the pressing process is avoided, as a result of which the press connection produced in this way is free of cracks and therefore operates reliably.
  • the compression pressure is detected only via the measurement of the path or the pressure, but not via a force measurement.
  • wall thickness variations of the injection materials can not be monitored accurately enough.
  • the plug is therefore made of a deformable metal material, such.
  • a deformable metal material such as a steel sheet, an aluminum material, stainless steel and the like deformable solid materials more.
  • the desired degree of pressing (variable) is thus always achieved independently of wall thickness, both from the hose and from the plug.
  • At least one sensor is used, but preferably a plurality of sensors, which are installed in the so-called inclined slides, which oblique slides are each connected with their front free ends with a spreading jaw.
  • the expansion jaws engage in the interior of the plug to be deformed and lead with a correspondingly radially outward directed Sp Dreckter the Verpressnut on the inside of the plug (directed radially outward).
  • the sensors which measure deformation are arranged in the inclined slides.
  • the spreading mechanism consists essentially of a rotationally driven spindle on which a spindle nut moves, which converts its axial movement into a corresponding, radial spreading movement of the expanding jaws.
  • a wedge slide is attached to the spindle nut, and the wedge slide also performs an axial movement with the spindle nut.
  • the spindle nut acts on an inclined slide, which is forced to a radial movement and which consequently drives the expanding jaws in the radial direction.
  • FIG. 1 It is shown that a preferably made of a metal material plug 10 forms an annular space 17, in which the front end face of a tube 11 is inserted and fixed there with an inwardly directed Verpressnut 15.
  • the plug 10 consists of an inner and an outer part, which together form the annular space 17 at the free rear end.
  • the inner and outer parts are materially connected to each other.
  • a receptacle 29 connects to a sealing ring 18, which then results in a sealing connection, not shown, with the pipe joint.
  • the nozzle is then inserted into the interior of the plug 10 and fixed there.
  • FIGS. 2 to 7 show the same parts of the device in different representations.
  • the same reference numerals have been used, so that - even if certain reference numerals are not indicated - the same parts are always present in the drawings in the same place.
  • the rotational movement 20 generated by an electric motor 1 is converted into an axial movement 21 by a roller screw drive consisting of a spindle 2 and a spindle nut 3.
  • the Keilschieber 4 fixed on the nut mounting 5.
  • this fixation and by a keyway connection between the spindle 2 and wedge slide 4 of the wedge slide 4 also performs an axial movement, since this 7 can perform only axial movement 21 through the guide columns 6 and the linear ball bushings.
  • Due to the axial movement of the wedge slide are inclined by 8 degrees guide window in the wedge slide 4, the oblique slides 8 to a radial movement 22, since they can perform 26 no axial movement through the fixed radial guides.
  • each spreader 9 is associated with associated mounting screws 27 with the front, free ends of the respective associated inclined slide 8.
  • the expanding jaws 9 are taken in a tool holder 19 in which an axial and radial guide 23 for the plug positioning of the plug 10 is present.
  • the plug is plugged onto the front of the spreader jaws 9 and secured against rotation by a groove.
  • FIG. 2 and 5 It follows, moreover, that a support plate 24 is present, on which the radial guides 26 are fastened, which serve for the radial guidance of the oblique slides 8.
  • FIGS. 6 and 7 is still the radial expansion shoulder 16 shown, wherein in FIG. 6 the spreading tool in rest position and in FIG. 7 in working position. It can be seen that thus the wedge slide 4, 4a have migrated in the axial direction forward in the direction of the spreading jaws 9 and at the same time the spreader jaws 9 were displaced outward in the radial direction, so that the Sp Drschulter 16 at the front free ends of the spreader 9th the material of the plug from the inside in the direction of arrow 22 (see also FIG. 1 ) radially outwardly directed plastically deformed.
  • the entire spreading device is flanged to the electric motor 1 via a fastening plate 25.
  • FIG. 3 shows, moreover, that the wedge slide is formed in two parts and consists of two spaced-apart wedge slides 4, 4a, which are screwed together by means of screw 28.
  • the invention is not limited thereto. It has already been pointed out in the general part that the wedge slide 4, 4a can also be designed as a tube and this tube can be moved in a certain way by a linear drive.
  • the wedge slide 4, 4a form a material integral, coherent part.
  • a gap 30 is formed according to FIG. 7 between the evenly distributed on the circumference arranged spreading jaws. 9
  • a sensor 13 is arranged in the region of the spreading tool, preferably in the region of the oblique slide.
  • each slanted slide 8 is assigned its own sensor 13.
  • every second or every third inclined slide 8 is equipped with a corresponding sensor.
  • FIG. 8 further details of the construction of the bore 31 show.
  • the bore 31 in the middle forms two opposite webs 33, between which a receiving bore 34 is formed.
  • this receiving bore engages approximately knob-shaped sensor 13 with its collar of reduced diameter and is recorded there in a form-fitting manner in the receiving bore 34.
  • the ring-running webs 33 also act on the collar of the sensor 13 over the entire circumference and thus uniformly detect all forces acting on the circumference in the direction of the deformation force 35.
  • the sensor 13 is fixed in the receiving bore 34 in such a way that it has a head of increased diameter, and is welded to the web of the smaller diameter with the web 33 so as to hold the sensor in the receiving bore 34 in a non-displaceable and positive manner.
  • the advantage of the control is that regardless of the wall thicknesses of the hose, the pipe, the Teckers always on the desired - depending on the path / wall thickness, set - pressing degree is pressed.
  • FIG. 9 on the ordinate the deformation force is shown, while on the abscissa the path of the deformation is shown. More precisely, it is the path which the expansion shoulders 16 of the expanding jaws 9 execute in the radial direction.
  • Verpresskurve 38 which represents the relationship between the pressing force and Verpressgrad.
  • the injection curve can also take a different form. This is shown with the Verpresskurve 40.
  • the desired force is determined at position 41, which is necessary for the compression and which represents the final force. In this case, the maximum force F max should not be exceeded.
  • FIG. 9 shows with the straight line 45 in total the tube wall thickness between a minimum and a maximum value.
  • the hose wall thickness is defined for a thick hose at position 44, then it can be seen in the diagram that a relatively high pressing force is required.
