Definitions

  • the drive is arranged on the frame and coupled to the support arm or possibly the carriage by means of a lever.
  • a lever can in particular be coupled between a pivot point at which the lever is rotatably mounted on the frame and a point of application of the drive on the lever with the support arm or possibly via the slide. It is also possible to arrange the drive in a different position on the frame.
  • a further guide device is provided on the punch riveting device, which is arranged on the frame of the punch riveting device and is spaced from the guide device when viewed perpendicular to the joining direction and in which the support arm can be guided in the joining direction. So there are two guide devices by means of which the support arm is guided, whereby an even higher torsional strength is achieved becomes.
  • the drive can then be used as previously explained. A connection is then only necessary on one of the sleds, for example.
  • a punch riveting device 200 according to the invention is shown schematically in a preferred embodiment.
  • the punch riveting device 200 has a vibration system 39 with a vibration converter 30, booster 31 and sonotrode or punch 15.
  • the oscillating system 39 is attached to a support arm 70. This can be done either directly or, for example, by means of a suitable holder, as in FIG Figure 2 shown. Such a holder would then be attached to the side of the support arm 70 and not to the drive.

Claims (14)

  1. Dispositif de rivetage auto-perforant (200, 300, 400, 500, 600, 700) destiné à relier au moins deux composants (11, 12) au moyen d'un rivet (20), ledit dispositif comprenant un poinçon (15) et un contre-support (18), entre lesquels au moins deux composants (11, 12) et le rivet (20) peuvent être disposés, un système vibrant (39) comportant le poinçon (15) et un convertisseur de vibrations (30) qui est couplé ou peut être couplé à un générateur de vibrations (32) de telle sorte que le système vibrant (39) puisse être excité de façon à vibrer, et un entraînement (50) permettant de soumettre le système vibrant (39) et donc le poinçon (15) à une force (F) et de le déplacer dans une direction d'assemblage (R) pour presser un rivet (20), disposé entre le poinçon (15) et un composant (11), dirigé vers le poinçon, des au moins deux composants au moyen du poinçon (15) dans les au moins deux composants (11, 12), caractérisé par un moyen de guidage (75) qui est disposé sur un cadre (60) du dispositif de rivetage auto-perforant et dans lequel un bras de support (70), en formant un angle supérieur à 0° et inférieur à 180°, en particulier supérieur à 45° et inférieur à 135°, en particulier sensiblement perpendiculaire, par rapport à la direction d'assemblage (R), peut être guidé dans la direction d'assemblage (R) et peut être déplacé au moyen de l'entraînement (50), le système vibrant (39) étant disposé sur le bras de support (70) à distance du moyen de guidage (75), vu perpendiculairement à la direction d'assemblage (R), le bras de support (70) comprenant un matériau plus rigide que le cadre (60) ou est formé avec une construction en treillis, une construction tubulaire ou un profilé.
  2. Dispositif de rivetage auto-perforant (400, 600) selon la revendication 1, l'entraînement (50) étant disposé sur le cadre (60) et relié directement au bras de support (70).
  3. Dispositif de rivetage auto-perforant (200, 300) selon la revendication 1, l'entraînement (50) étant disposé sur le cadre et étant couplé au bras de support (70) au moyen d'un levier (51).
  4. Dispositif de rivetage auto-perforant (300) selon la revendication 3, le levier (51) étant accouplé au bras de support (70) au moyen d'un guide à coulisse.
  5. Dispositif de rivetage auto-perforant (500, 600, 700) selon la revendication 1, l'entraînement (50) étant intégré dans le moyen de guidage (75) et étant conçu en particulier comme un entraînement linéaire.
  6. Dispositif de rivetage auto-perforant (200, 300, 400, 500, 600, 700) selon l'une des revendications précédentes, le bras de support (70) étant relié de manière fixe à un chariot (71) qui est guidé dans le dispositif de guidage (75).
  7. Dispositif de rivetage auto-perçant (400) selon l'une des revendications précédentes, comprenant un autre moyen de guidage (76) qui est disposé à distance du moyen de guidage (75) sur le cadre (60) du dispositif de rivetage auto-perforant, vu perpendiculairement à la direction d'assemblage (R), et dans lequel le bras support (70) peut être guidé dans la direction d'assemblage.
  8. Dispositif de rivetage auto-perforant (200, 300, 400, 500, 600, 700) selon l'une des revendications précédentes, un élément de compensation (85, 86) étant prévu qui est disposé dans le dispositif de rivetage auto-perforant de telle sorte que, lorsque l'élément de compensation est déplacé, l'orientation du poinçon et du contre-support l'un par rapport à l'autre change.
  9. Dispositif de rivetage auto-perforant (600, 700) selon la revendication 8, l'élément de compensation (85) étant disposé dans le bras de support (70) ou dans le cadre.
