Description
Verfahren zum Herstellen von unterschnittenen Hohlansätzen in Spundwandeisen und U-Eisen-durch Walzen In vielen Fällen, insbesondere bei Eisenspundwänden, U-Eisen und ähnlichen Profilen, ist es erwünscht, eine unterschnittene Nut für Verbindungsnvecke mit gleichartigen Profilen vorzusehen, um dadurch die vielseitige Möglichkeit der Zusammensetzung zu erhalten.Process for the production of undercut hollow sockets in sheet piling iron and U-iron-by rolling In many cases, especially with iron sheet piling, U-iron and similar profiles, it is desirable to have an undercut groove for connecting corners to be provided with similar profiles, thereby the versatile possibility of Composition.
Gemäß der Erfindung wird die unterschnittene Nut dadurch erzeugt, daß bis zu dem dem Endkaliber vorausgehenden Vorkalibei die Ansätze rechtwinklig, die zwischen dem Hohlansatz und den Flanschen bzw. zwischen den Hohlansätzen und zwischen Hohlansätzen und Flanschen liegenden Stegteile im Bogen, im Winkel, in Wellenform oder in Schräglage vorgewalzt und dann im Endkaliber durch eine glatte Oberwalze geradegestreckt werden. Auf diese Weise wird sich die Nut durch Schrägstellen der Seitenwände an der Mündung verengen., so daß eine Unterschneidung entsteht.According to the invention, the undercut groove is produced by that up to the pre-caliber preceding the final caliber, the approaches are right-angled, between the hollow approach and the flanges or between the hollow approach and web parts lying between hollow projections and flanges in a curve, at an angle, in Wave form or in an inclined position and then rolled in the final pass through a smooth The top roller should be straightened. In this way, the groove will be inclined narrow the side walls at the mouth, so that an undercut is created.
Es wurde zwar bereits für rinnenförmige Oberlichtfenstersprossen aus Walzeisenprofilen vorgeschlagen, die nach einwärts geneigten Seitenwände dadurch herzustellen, daß vorerst ein Profil finit einem nach einwärts gebogenen oder erhabenen Bodenteil und senkrechte Seitenwände gewalzt wurden, worauf durch Geradewalzen des Bodens ein Einwärtsstellen der Seitenwände bewirkt wurde. Dieses Verfahren läßt sich aber für Spundwände, U -Eisen und ähnliche Profile, bei denen eine zur Größe des Profils verhältnismäßig schmale Nut bedingt ist, nicht anwenden, weil bei dem bekannten Verfahren das Profil durch eine schmale Walze läuft, die in ihrem mittleren Teile so schmal ist; daß sie durch die obere Breite der fertigen unterschnittenen Nut hindurchlaufen kann, während solche schmalen Walzen nicht imstande sind, bei dem ungleich anderen Verhältnis von Nut zum Profil diese durchzudrücken und unterschnitten zu gestalten.It was already made for gutter-shaped skylight window bars Roll iron profiles proposed, the inwardly inclined side walls thereby produce that initially a profile finite an inwardly curved or raised Bottom part and vertical side walls were rolled, whereupon by straightening the Bottom an inward positioning of the side walls was effected. This procedure leaves but are suitable for sheet piling, U-irons and similar profiles, where one size the profile is relatively narrow groove is conditional, do not use, because in the known method, the profile runs through a narrow roller in its middle Parts is so narrow; that they undercut through the top width of the finished Groove can pass through, while such narrow rollers are unable to to push them through and undercut the unequal ratio of the groove to the profile to design.
Die Durchfi}hrung des Verfahrens gemäß der Erfindung ist an verschiedenen Ausführungsbeispielen gezeigt, und zwar ist in Abb. i und z das Verfahren näher erläutert, während in Abb. 3 ein Profil mit anderen unterschnittenen Nuten gezeigt ist.The method according to the invention can be carried out in various ways Embodiments shown, namely in Fig. I and z the method is more detailed explained, while in Fig. 3 a profile with other undercut grooves is shown is.
Es ist dabei - vollkommen gleichgültig, ob es sich um Profil- oder Stabeisen handelt; ob das Walzen auf kaltem oder warmem Wege erfolgt. Das neue Verfahren ,kann selbstverständlich auch auf Nichteisenmetalle in gleicher Weise angewendet werden.It is there - completely irrelevant whether it is profile or Bar iron acts; whether the rolling takes place on a cold or warm route. The new procedure , can of course also be applied to non-ferrous metals in the same way will.
