  • the above-described method for producing threaded structures in sleeves is not limited to cylindrical sleeves. In principle, it is also in parallelepiped sleeves, which are used in particular for proximity switches or position sensors used. Cylindrical sleeves with corresponding threaded parts are used in particular in fluid sensors. Particularly preferably, the method described above for the production of process connections is used and can thus also in key engagement areas, which are used by rotatable hexagonal elements, which in turn can be produced as deep-drawn parts.
  • the above-described method for producing such threaded portions and the apparatus for producing these threaded portions it is possible to introduce threaded portions as an integral part of a device, which in turn is produced by deep drawing. In this case, sensor housing can be correspondingly threaded, which consist of two parts and are connected to each other.
  • the method can be applied to virtually all electrical or electronic devices, in particular proximity switches, process measuring instruments and the like.

Abstract

Ce procédé pour fabriquer un filetage extérieur dans un manchon (100) est caractérisé en ce qu'une force (Fx) agissant radialement de l'intérieur vers l'extérieur est exercée, sur au moins un élément (210) disposé à l'intérieur du manchon (100) et présentant une structure filetée (220) sur sa surface - élément qui coopère avec au moins un élément complémentaire (300) entourant le manchon (100) et présentant une structure intérieure complémentaire de la structure filetée (220) - de telle sorte que le filetage est produit par déformation du manchon (100).
