Description

Verfahren zur Herstellung eines Innengewindes in dünnen Blechen Die Erfindung bezieht sich auf ein Verfahren zur Verbindung einer Lochscheibe mit einem Blech und zur Herstellung eines Innengewindes, das besonders für Massenfertigung geeignet ist.Process for producing an internal thread in thin sheet metal The invention relates to a method for connecting a perforated disk to a Sheet metal and for the production of an internal thread, which is particularly suitable for mass production suitable is.

Es ist bereits bekannt, Innengewinde dadurch herzustellen, daß man den Werkstoff des Werkstückes mittels .eines Werkzeuges an einen das entsprechende Gewinde tragenden Dorn ,anpreßtoder andrückt. Lieses Verfahren ist bei harten Werkstoffen mit Schwierigkeiten verbunden.It is already known to produce internal threads in that one the material of the workpiece using .eines tool to a corresponding Thread-bearing mandrel, presses or presses. This procedure is for hard materials associated with difficulties.

Es ist ferner bekannt, bei dünnen Blechen zunächst in dem Blech ein Loch größeren Durchmessers anzubringen und in dieses Blech eine Scheibe größerer Dicke zu befestigen, beispielsweise einzunieten. In diese Scheibe wird dann das Gewindeeingebracht.It is also known, in the case of thin metal sheets, first of all in the sheet metal To attach a hole of larger diameter and in this sheet a larger disc To fasten thick, for example riveting. This will be in this disc Threaded.

Außerdem ist es bekannt, eine Lochscheibe auf einer Welle 'durch Einpressung von Ringnuten zu befestigen. Durch die dabei auftretende radiale Verdrängung des Werkstoffes wird die Reibung zwischen Welle und Scheibe derart vergrößert, daß eine ausreichende Scheibenbefestigung für kleine Beanspruchungen erzielt wird.It is also known to press a perforated disk onto a shaft to fasten by ring grooves. Due to the radial displacement of the Material, the friction between the shaft and disc is increased so that a Sufficient pane fastening is achieved for small loads.

Erfindungsgemäß wird die Verbindung einer Lochscheibe mit .einem Blech und ein Innengewinde in der Lochscheibe dadurch hergestellt, daß durch ,axiales Einpressen von einander gegenüberliegenden Ringnuten in die Ober- und Unterseite der Lochscheibe der Scheibenwerkstoff gleichzeitig radial einwärts zur Bildung des Innengewindes um einen in das Loch der Lochscheibe @eingeführten Gewindeformdorn und radial auswärts zur Bildung der die Ober- und Unterfläche dies Bleches übergreifenden Nietverbindung verdrängt wird.According to the invention, the connection of a perforated disk with .einem sheet metal and an internal thread in the perforated disc produced in that by, axial Pressing ring grooves opposite one another into the top and bottom the perforated disk of the disk material at the same time radially inwards to form the Internal thread around a thread-forming mandrel inserted into the hole in the perforated disc @ and radially outwards to form the upper and lower surfaces of this sheet overlapping Riveted connection is displaced.

In den Fig. i und -- ist das Verfahren bildlich dargestellt. In das Werkstück, z. B. ein Blech, wird ein Loch von größerem Durchmesser als dem des Gewindes gestanzt oder gebohrt und in dieses Locheine Scheibe 2 aus einem weicheren Werkstoff als dem des Werkstückes, beispielsweise aus Messing, Kupfer, Aluminium o. dgl., eingelegt. Diese Scheibe? hat in der Mitte ein Loch 3, in das der Dorn q: mit dem Gewinde 5 hineinp:aßt. Zweckmäßigerweise ist die Stärke der Scheibe z etwas größer ,als die des Bleches ;. Durch die beiden Stempel 6 und 7 wird dann der weiche Werkstoff z so zusämmengepreßt, der der Werkstoff einerseits die Gänge des Gewindes 5 ausfüllt und anderseits auf seinem äußeren Umfang um die Lochränder des. Bleches r herumquillt. Das fertige Stück ist in der Fig. z dargestellt. Um ein Verdrehen des Teiles 2 in dem Blech i zu verhindern, kann es zweckmäßig sein, das Loch in dem Blech i mit Einkerbungen :o. dgl. zu versehen, in die sich der Scheibenw!erkstOff 2 einpreßt.In Figures i and -., The method is depicted. In the workpiece, e.g. B. a sheet metal, a hole with a larger diameter than that of the thread is punched or drilled and a disc 2 made of a softer material than that of the workpiece, for example brass, copper, aluminum or the like, is inserted into this hole. This disc ? has a hole 3 in the middle, into which the mandrel q: with the thread 5 p: ate. Appropriately, the thickness of the disk z is somewhat greater than that of the sheet metal; The soft material z is then pressed together by the two punches 6 and 7 in such a way that the material on the one hand fills the threads of the thread 5 and on the other hand swells around the hole edges of the sheet metal r on its outer circumference. The finished piece is shown in FIG. In order to prevent the part 2 from rotating in the sheet i, it may be useful to provide the hole in the sheet i with notches: o. Like. To be provided, into which the windshield material 2 is pressed.
