When a predetermined tensile force is reached, the mandrel preferably tears off flush with the setting head.
  • a rivet connection as can be seen, for example, from WO 00/68583, is used in various areas of technology, including in the automotive industry. When blind rivets are used to join body components in a motor vehicle, the body disadvantageously forms a type of resonance body.

  • blind rivet technology cannot be easily integrated into an assembly line process. Furthermore, the disposal of the torn off residual mandrel is complex.
  • the blind rivet is usually set manually with the aid of a hydraulically actuated setting tool designed in the manner of a pistol. Process monitoring is difficult due to the essentially manual setting.

  • the advantages of screw blind rivets are that there is no tearing noise, that no residual mandrel has to be disposed of, and that existing tools can be used on the assembly line, for example in automobile production. In particular, this offers the possibility of using proven and established process monitoring systems for quality inspection.
  • the setting process of the blind rivet is expediently monitored automatically and this monitoring is in particular also recorded centrally. Since the setting process is ended with the aid of a screwing process, a torque monitoring which is customary in screwing technology can be used for this.

  • the blind rivet has a rivet sleeve with a rivet mandrel formed therein.
  • the screw already engages with a thread in the rivet sleeve, so that force can be introduced into the rivet sleeve during the setting process due to the translational pulling.
  • the screw is designed in such a way that, when the screw is tightened, the greatest possible proportion of the force applied is converted into a translational component for any residual shaping that may still be necessary to form the closing bead and to generate the desired pretension.

Furthermore, the outer circumference of the thread tapers towards the thread tip 36 in order to enable easy insertion. Due to the non-circular cross-sectional geometry, only a partial area of the thread 20 is in engagement with the sleeve material.

Abstract

Lors de l'assemblage de deux composants (22A, B), ces composants (22A, B) sont reliés l'un à l'autre au moyen d'un rivet aveugle à visser (2) dans un processus de mise en place en une étape. A cet effet, ces composants sont directement serrés entre un rebord (8) d'un corps de rivet (4) et un renflement de fermeture (26) tout comme lors d'un assemblage par rivet aveugle classique. Un mandrin de rivet, conçu sous la forme d'une vis (6), est placé dans le corps de rivet (4) et entre en prise avec ce corps de rivet (4) avec son filetage (20). Pour réaliser cet assemblage rivé, la vis (6) est d'abord soumise à une traction translationnelle puis bloquée par vissage. Afin de convertir le couple de rotation appliqué le plus largement possible en une composante de force translationnelle, le filetage (20) présente une géométrie de section transversale ovale. De façon alternée ou simultanée, ce filetage (20) présente des flancs (32A, B) à différents angles de filet (alpha, ß), l'angle de filet (a) des flancs (32A) faisant face à la tête de vis (16) étant inférieur à l'angle de filet (ß) des flancs (32B) opposés à la tête de vis (16).
