Description
Tiefgezogene Niete als Spreizkegel ausgebildet Im Tiefziehverfahren sind beim verformen von thermoplastischen Kunststoffen an bestimmten Stellen vorteilhaft Nieten anzubringen, die dann im Tiefziehverfahren sich als erhabene oder vertiefte Hohikörper ausbilden. Nachdem zwei oder mehrere Hohikörper ineinandergesteckt und gequetscht werden, entstehen so auf diese Art und Weise -Nietverbindungen.Deep-drawn rivets designed as expanding cones in the deep-drawing process are advantageous when deforming thermoplastics at certain points To attach rivets, which then turn out to be raised or recessed in the deep-drawing process Form hollow bodies. After two or more hollow bodies are plugged into each other and are squeezed, riveted connections are created in this way.
Zu diesen Nietverbindungen bedarf es der Deformation des Materials wie bei allen Vernietungen. Dadurch entstehen aber unschöne Velwellungen rund um die Vemietungsstelle.These riveted connections require the material to be deformed as with all rivets. But this creates unsightly Velwellen all around the rental point.
Die Niete wird ebenfalls unansehnlich da sie durch den Druck zusammengekruppelt wird.The rivet also becomes unsightly because the pressure causes it to crumple will.
Die Haltbarkeit derartiger Nieten ist sehr unterschiedlich, da die Deformation mehr oder weniger unregelmäßig und willkürlich erfolgt.The durability of such rivets is very different because the Deformation occurs more or less irregularly and arbitrarily.
Eine in ihrer Festigkeit berechenbare und sauber aussehende Niete ist die Ausbildung der Niete als Spreizkegel. Abb. la zeigt die Niete nach dem Tiefziehen. Sie besteht aus einer leicht konischen Basis 1 und aus einem kegelförmigem Abschluß 2. Wesentlich ist, daß die Niete von der Spitze 3 rudial über den Kegel und der Basis laufende Rillen aufweist.4. Diese Rillen erlauben dann ein spreizen der Basis 1 als auch des Kegels 2 wenn die Spitze 3 gedruckt wird. Dadurch ergibt sich fUr die Niete eine Hinterschneidung im Punkt 5, was ein zusammennieten von zwei Folien bewiiict. Die radialen Rillen 4 erlauben ein spreizen des Materials ohne daß unschöne Deformationen entstehen. Ebenso entstehen keine Defonnationen um die Nietstelle herum. Je nach Ausbildung der Basis und des Kegels kann ein sehr fester Verschluß, bzw. auch eine Art Druckknopfniete hergestellt werden.A rivet with predictable strength and a clean-looking rivet is the design of the rivet as an expanding cone. Fig. La shows the rivet after deep drawing. It consists of a slightly conical base 1 and a conical end 2. It is essential that the rivet from the tip 3 rudially over the cone and the Base has running grooves. 4. These grooves then allow the base to expand 1 as well as cone 2 when the tip 3 is printed. This gives for the rivet has an undercut at point 5, which is a riveting of two foils bewiiict. The radial grooves 4 allow the material to expand without being unsightly Deformations arise. There are also no deformations around the riveting point hereabouts. Depending on the design of the base and the cone, a very solid lock, or a kind of snap rivet can be produced.
