Die Auflageplatte 12 des Befestigungswerkzeuges ist mit Bohrungen 28 versehen, deren Anordnung genau der Anordnung der Ausnehmungen 24 in dem Gestängeteil 16 entspricht.Description of the invention In Figure 1, a tool is shown, with which the process according to the invention can be carried out. The tool consists of three individual parts, one of which forms an embossing tool 10. The second The tool part is a support plate 12, which is arranged above the embossing tool 10 is. A riveting tool 14 is again located above the support plate 12. The tool parts 10, 12 and 14 are arranged to move toward and away from each other can be. The embossing tool is in a starting position shown in FIG 10 and the support plate 12 so far apart that one on a component 16 to be fastened element 18 together with the component 16 between the embossing tool 10 and the support plate 12 can be introduced. The component 16 is described in FIG Embodiment through a transmission linkage of a wiper device for windows Formed by motor vehicles, while the element 18 is a plastic bearing for a is in this guided pivot pin. The bearing element 18 has a base plate 20, on which fastening pins 22 are integrally formed. The mounting studs 22 of the bearing element 18 are inserted into recesses 24 of the rod part 16 and protrude with its free end 26 on the side of the transmission rod facing away from the base plate 20 16 out. The support plate 12 of the fastening tool is provided with bores 28 provided, the arrangement of which exactly corresponds to the arrangement of the recesses 24 in the rod part 16 corresponds.

Das Nietwerkzeug 14 weist zapfenartige Xopfsetzer 30 auf, welche in den Bohrungen 28 der Auflageplatte 12 geführt sind. An ihrer den freien Enden 26 der Befestigungszapfen 22 zugewandten Stirnfläehe sind die Kopfsetzer 30 jeweils mit einer Kehlung 31 versehen, welche im Betrieb der Vorrichtung die Verformung der freien Zapfenenden 26 vornimmt. Auf seiner der Bodenplatte 20 zugewandten Fläche weist das Prägewerkzeug 10 warzenartige Erhöhungen 32 auf, deren Anordnung ebenfalls mit dem Bild der Ausnehmungen 24 in dem Gestängeteil 16 bzw. mit dem Bild der Bohrungen 28 in der Auflageplatte 12 übereinstimmt.The riveting tool 14 has peg-like Xopfsetzers 30, which in the bores 28 of the support plate 12 are guided. At their free ends 26 the end face facing the fastening pin 22 are the head setters 30 in each case provided with a groove 31, which the deformation during operation of the device the free pin ends 26 makes. On his the bottom plate 20 facing surface, the embossing tool 10 has wart-like elevations 32, the Arrangement also with the image of the recesses 24 in the rod part 16 or corresponds to the image of the holes 28 in the support plate 12.

Das erfindungsgemäße Befestigungsverfahren läuft wie folgt ab: Nachdem das Gestängeteil. 16 und das Lagerelement 18 in der in Figur 1 dargestellten Weise in das Befestigungswerkzeug 10, 12, 14 angebracht worden ist, werden die Auflageplatte 12 und das Prägewerkzeug 10 gegeneinander bewegt - vergleiche dazu die gestrichelte Darstellung der Werkzeugteile - wobei die beiden miteinander zu verbindenden Teile 16 und 18 zwischen den beiden Werkzeugteilen 10 und 12 zusammengepreßt werden.The fastening method according to the invention proceeds as follows: After the linkage part. 16 and the bearing element 18 in the manner shown in FIG has been attached to the fastening tool 10, 12, 14, the platen 12 and the embossing tool 10 moved against each other - compare the dashed line Representation of the tool parts - with the two parts to be connected 16 and 18 are pressed together between the two tool parts 10 and 12.

Dabei werden die Erhöhungen 32 des Prägewerkzeugs 10 auf der von den Befestigungszapfen abgewandten Seite der Bodenplatte 20 in die Bodenplatte 20 hineingedrückt (vergleiche dazu die gestrichelte Darstellung 32' der Erhöhungen 32). Wegen der oben beschriebenen Anordnung der Erhöhung 32 erfolgt die Einprägung der Erhöhungen 32 in die Bodenplatte 20 im Zentrum der Projektionsfläche der Befestigungszapfen 22. Weil das Lagerelement 18 aus einem bei Raumtemperatur unter Druck plastisch verformbaren Kunststoff besteht und die Bodenplatte 20 mit ihrer auf der Seite der Befestigungszapfen 22 befindlichen Schulterfläche 34 an dem Gestängeteil 16 und dieses wiederum an der Auflageplatte 12 angelegt ist, wird beim Zusammenfahren der Teile 10 und 12 des Befestigungswerkzeuges eine plastische Verformung der Bodenplatte 20 bewirkt. Durch das Hineinpressen der Erhöhungen 32 des Prägewerkzeuges 10 in die Bodenplatte 20 des Lagerelements 18 werden die Befestigungszapfen 22 etwas aus den Ausehmunge 24 des Gestängeteils 16 herausgedrückt (vergleiche dazu die gestrichelte Darstellung 22' der Befestigungszapfen 22). In dieser Stellung des Befestigungswerkzeuges, welche über einen bestimmten Zeitraum beibehalten wird, wird nun das Nietwerkzeug 14 in Richtung des Pfeiles 36 gedrückt. Dabei werden die freien Enden 26 der Befestigungszapfen 22 nietkopfartig verformt. Danach wird das Befestigungswerkzeug 10, 12, 14 wieder auseinandergefahren und das Gestängeteil 16 mit dem an ihn befestigten Lagerelement 18 herausgenommen.The elevations 32 of the embossing tool 10 are on the of the Fastening pin facing away from the base plate 20 is pressed into the base plate 20 (Compare with this the dashed representation 32 'of the elevations 32). Because of the The above-described arrangement of the elevation 32 is followed by the embossing of the elevations 32 in the base plate 20 in the center of the projection surface of the fastening pin 22. Because the bearing element 18 is plastic from a room temperature under pressure deformable plastic and the bottom plate 20 with her on the side of the Fastening pin 22 located shoulder surface 34 on the rod part 16 and this in turn is applied to the support plate 12, is when the Parts 10 and 12 of the fastening tool undergo plastic deformation of the base plate 20 causes. By pressing in the elevations 32 of the embossing tool 10 in the base plate 20 of the bearing element 18, the fastening pins 22 are somewhat off the recesses 24 of the rod part 16 pushed out (compare the dashed Representation 22 'of the fastening pin 22). In this position of the fastening tool, which is maintained over a certain period of time, now becomes the riveting tool 14 pressed in the direction of arrow 36. Included become the free Ends 26 of the fastening pins 22 are deformed in the manner of a rivet head. After that, the fastening tool 10, 12, 14 moved apart again and the rod part 16 with the attached to it Bearing element 18 removed.

Bei dem in Figur 2 dargestellten Schnitt durch die miteinander verbundenen Teile 16 und 18 ist die nietkopfartige Verformung 36 erkennbar. Weiter sind auch die innerhalb der Projektionsfläche der Befestigungszapfen 22 befindlichen Einprägungen 38 zu sehen, welche durch die Erhöhungen 32 erzeugt worden sind.In the section shown in Figure 2 through the interconnected Parts 16 and 18, the rivet head-like deformation 36 can be seen. Next are too the embossments located within the projection surface of the fastening pins 22 38, which have been produced by the bumps 32.

In dem in Figur 3 dargestellten Spannungsdiagramm ist die Anpreßspannung zwischen der Bodenplatte 20 des Lagerelements 18 und dem Ubertragungsgestänge 16 dargestellt. Der Diagrammpunkt 40 zeigt eine Spannung Null an, wie sie vorhanden ist, wenn die beiden miteinander zu verbindenden Teile 16 und 18 gemäß Figur 1 zusammengesteckt sind. Nach dem ersten Verfahrensschritt, bei welchem die beiden miteinander zu verbindenden Teile 16 und 18 zusammengepreßt werden, wird eine Spannung gemäß dem Punkt 42 erreicht. Die Spannung 42 steigt auf einen Punkt 44 an, wenn durch das Nietwerkzeug 14 die Verformungen 36 angebracht werden. Nach dem öffnen des Befestigungswerkzeuges 10, 12, 14 fällt die Spannung zwischen Bodenplatte 20 und dem Übertragungsgestänge 16 auf einen durch den Punkt 46 markierten Wert ab. Es zeigt sich also, daß nach dem Herausnehmen des Gestängeteils 16 und des Lagerelements 18 aus dem Befestigungswerkzeug 10, 12, 14 noch eine Restspannung 46 vorhanden ist, durch welche die beiden miteiandner verbundenen Teile 16, 18 fest aneinandergezogen werden. Dies wird dadurch erreicht, daß bevor die Verformungen 36 an die freien Enden 26 der Befestigungszapfen 22 angeformt werden, das Lagerelement 18 auf seiner von der Schulter 34 abgewandten Seite im wesentlichen innerhalb der Projektionsfläche der Zapfen 22 belastet wird und daß während der Belastungsphase die Verformung 36 an den freien Enden der Zapfen vorgenommen wird.In the voltage diagram shown in Figure 3, the contact voltage is between the base plate 20 of the bearing element 18 and the transmission linkage 16 shown. The diagram point 40 indicates a voltage zero as it is present is when the two parts 16 and 18 to be connected to one another are plugged together as shown in FIG are. After the first process step in which the two are to be connected to one another Parts 16 and 18 are pressed together, a tension according to point 42 is achieved. The tension 42 increases to a point 44 when the riveting tool 14 the Deformations 36 are attached. After opening the fastening tool 10, 12, 14, the tension between the base plate 20 and the transmission linkage 16 falls to a value marked by point 46. So it turns out that after Removing the rod part 16 and the bearing element 18 from the fastening tool 10, 12, 14 there is still a residual tension 46, through which the two together connected parts 16, 18 are tightly pulled together. This is achieved by that before the deformations 36 are formed on the free ends 26 of the fastening pins 22 be, the bearing element 18 on its side facing away from the shoulder 34 in essential is loaded within the projection area of the pin 22 and that during the Load phase the deformation 36 is made at the free ends of the pin.

Bei diesem Verfahren wird die Elastizität des Werkstoffes aus dem das Lagerelement besteht benutzt um die bleibende Restspannung zu erzeugen.In this process, the elasticity of the material from the the bearing element is used to generate the remaining residual stress.
