Description

Verfahren zur Herstellung von Scheibe», insbesondere Radscheiben, mit mittlerer Öffnung und gegebenenfalls zylindrischem Rand Die Erfindung bezieht sich auf die Herstellung von kreisrunden Metallscheiben, die in der Mitte eine große Öffnung aufweisen, also die Form eines ebenen oder auch schwach kegelförmigen Kreisringes besitzen, wobei häufig der Rand -zylindrisch umgebogen ist. Derartige Scheiben kommen z. B. als Riemenscheiben, hauptsächlich aber für Automobilräder in Betracht, indem der zylindrische Rand als Unterlage für die Felge dient. Eine Ausführungsform einer derartigen Radscheibe ist durch Abb. r im Schnitt veranschaulicht. Eine solche Ringscheibe wird vorteilhaft unmittelbar an der Bremstrommel befestigt.Process for the production of disc », in particular wheel discs, with central opening and optionally cylindrical rim The invention relates focus on the manufacture of circular metal discs with a large one in the middle Have opening, so the shape of a flat or slightly conical circular ring have, the edge is often bent-cylindrically. Such discs are coming z. B. as pulleys, but mainly for automobile wheels into consideration by the cylindrical edge serves as a base for the rim. One embodiment of a such wheel disc is illustrated in section by Fig. r. Such a washer is advantageously attached directly to the brake drum.

Bei der Herstellung einer solchen Radscheibe ist es bisher üblich, aus einem viereckigen Blech zunächst eine runde Scheibe auszustanzen, die dann abgedreht oder gewalzt wird, woran sich dann die Erzeugung der eigentlichen Radscheibenform anschließt. Dieses Verfahren erfordert einen übergroßen Materialaufwand und ist daher teuer.In the manufacture of such a wheel disc, it has hitherto been customary first punch a round disc out of a square sheet metal, which is then turned off or is rolled, which is then used to generate the actual wheel disc shape connects. This method requires an excessive amount of material and is therefore expensive.

Der Erfindung gemäß wird von einem Flacheisen ausgegangen. Der Querschnitt dieses Flacheisens wird, wie es an sich bekannt ist. zwischen kegelförmigen Walzen fortschreitend keilartig verjüngt und gerundet, und zwar so lange, bis ein offener Ring entsteht, der dann durch Verbinden, vorteilhaft Aneinanderschweißen, der Enden geschlossen wird. An der so entstandenen Ringscheibe mit nach außen sich verjüngendem Profil wird schließlich, falls die zu erzeugende Scheibe einen zylindrischen Rand haben soll, der Rand in einem Preß- oder Ziehverfahren umgelegt. Gleichzeitig kann, falls gewünscht, die Scheibe hierbei auch in eine Kegelform übergeführt werden. Die Länge des Flacheisens, von dem ausgegangen wird, entspricht dem inneren Umfang der fertigen Ringscheibe, falls die Innenkante dieser Scheibe die Stärke der Kante des ursprünglichen Flacheisens beibehält. Wird aber auch diese Kante dünner gewalzt, so ist das Ausgangsbandeisen natürlich kürzer zu wählen.The invention is based on a flat iron. The cross section this flat iron becomes, as it is known per se. between conical rollers progressively tapered and rounded like a wedge, until an open one Ring is created, which is then created by connecting, advantageously welding together, the ends is closed. On the ring disc that was created in this way, with an outward taper Finally, the profile becomes if the disc to be produced has a cylindrical edge should have turned the edge in a pressing or drawing process. At the same time, if desired, the disc can also be converted into a cone shape. The length of the flat iron assumed corresponds to the inner circumference of the finished washer, if the inner edge of this washer is the thickness of the edge of the original flat iron. But if this edge is also rolled thinner, so the starting bar should of course be chosen to be shorter.

Wie ersichtlich, wird das gesamte Material des Flacheisens, das überdies in der Anschaffung besonders billig ist, zur Erzeugung der fertigen Scheibe verwertet. Insbesondere wird auch für die häufig erwünschte Verjüngung nach dem äußeren Rand zu kein Material vergeudet und auch kein besonderer Arbeitsgang erforderlich.As can be seen, all the material of the flat iron, moreover is particularly cheap to buy, used to produce the finished disc. In particular, it is also used for the tapering towards the outer edge, which is often desired no material is wasted and no special operation is required.

In der Zeichnung ist in Abb. z das Bandeisen dargestellt, von dem ausgegangen wird. Abb. 3 zeigt das Flacheisen zwischen den beiden stumpfkegelförmigen Walzen a, a, die zweckmäßig geneigt gegeneinanderstehen, um den größeren Durchmesser der Stumpfkegel so groß machen zu können, daß er für die hier erforderliche Walzgeschwindigkeit ausreicht. Die Konizität der Walzen richtet sich nämlich nach der gewollten Streckung des Flacheisens. Wenn also z. B. der äußere Umfang des Ringes doppelt so - groß wie der innere Umfang des Ringes ist, so muß auch, weil sich in derselben Zeiteinheit am Außenumfang die doppelte Länge Flacheisen abwickelt, der Durchmesser der konischen Walzen außen doppelt so groß sein, wie er innen ist. Eine der Walzen ist vorteilhaft ausschwenkbar.In the drawing, Fig. Z shows the iron band from which it is assumed. Fig. 3 shows the flat iron between the two frustoconical rollers a, a, which are conveniently inclined to each other in order to make the larger diameter of the truncated cone so large that it is sufficient for the rolling speed required here. The conicity of the rollers depends on the desired stretching of the flat iron. So if z. B. the outer circumference of the ring is twice as large as the inner circumference of the ring, then, because twice the length of flat iron unwinds in the same time unit on the outer circumference, the diameter of the conical rollers on the outside must be twice as large as it is on the inside is. One of the rollers can advantageously be swiveled out.

In der in Abb. q. dargestellten Verfahrensstufe ist das Flacheisen im Begriff, sich zu runden und den verjüngten Querschnitt anzunehmen. Abb. 5 zeigt den fertiggewalzten Flachring, an dem auch schon die Fuge verschweißt ist. Aus diesem Ring wird schließlich die Radscheibe nach Abb. r erzeugt.In the in Fig.q. The process stage shown is the flat iron about to round off and take on the tapered cross-section. Fig. 5 shows the finish-rolled flat ring to which the joint is already welded. For this Ring, the wheel disc is finally produced according to Fig. R.
