Description
Die Herstellung von Förderrinnen o. dgl. nach Patent 255850 stellt sich teuer, weil es einerseits mit Schwierigkeiten und Kosten verbunden bzw. unmöglich ist, den der Abnutzung entsprechend ungleich starken Blechstreifen wegen seiner großen Dünne und Breite in einem Arbeitsgang gleich aus dem Block zu walzen und andererseits das darauf folgende Biegen dieses Blechstreifens zu dem fertigen Rutschenprofil einen weiteren Arbeitsgang notwendig macht. Bisher war das Verfahren folgendes: Zunächst wurden Grobblechtafeln abgewalzt, diese kamen dann nochmals in den Ofen, um im zweiten Arbeitsgang zu dem in der Mitte verdickten Blech ausgewalzt und nach dem Erkalten ; in einem dritten Arbeitsgang auf einer hydraulischen Presse in die Trogform gebracht zu werden.The production of conveyor troughs o. The like. According to patent 255850 is expensive because on the one hand it is associated with difficulties and costs or is impossible to roll the sheet metal strip, which is unequal to the wear, out of the block in one operation because of its great thinness and width and on the other hand, the subsequent bending of this sheet metal strip to the finished slide profile makes a further work step necessary. So far, the process was as follows: First, heavy plate sheets were rolled down, these were then put into the furnace again, in order to be rolled out to the sheet metal thickened in the middle in the second step and after cooling ; to be brought into the trough shape in a third operation on a hydraulic press.
Gemäß vorliegender Erfindung wird nun das Herstellungsverfahren des Patents 255850 dadurch ganz bedeutend verbilligt, daß die zweite Walzung und das Biegen des Blechstreifens zu dem endgültigen Rutschenprofil gleich mit im Walzwerk erfolgen. Dies wird dadurch ermöglicht, daß aus dem Block zunächst ein oder mehrere Zwischenprofile geringerer Breite und aus dem letzten der Zwischenprofile dann in demselben Walzwerk ohne erneute Erhitzung, also in einem einzigen Arbeitsgang, das fertige Rutschenprofil gewalzt wird.In accordance with the present invention, the manufacturing method of patent 255850 very significantly cheaper because the second rolling and bending of the sheet metal strip to the final chute profile at the same time in the rolling mill. This is made possible by first starting from the block one or more intermediate profiles of smaller width and from the last of the intermediate profiles then in the same rolling mill without renewed heating, i.e. in a single operation, the finished slide profile is rolled.
In der Zeichnung zeigtIn the drawing shows
Fig. ι den Block im Querschnitt;Fig. Ι the block in cross section;
Fig. 2 und 3 sind zwei verschiedene Zwischenprofile, und Fig. 4 und 5 fertige Rutschenquerschnitte.FIGS. 2 and 3 are two different intermediate profiles, and FIGS. 4 and 5 are finished slide cross-sections.
Die Zwischenprofile gemäß Fig. 2 und .3 haben in der Mitte eine der gebogenen Rinne entgegengesetzte Ausbauchung α, deren Wandstärke größer ist als die der fertigen Rinne. Diese Zwischenprofile werden dann in den nächsten Kalibern des Walzwerks noch weiter gestreckt und gleichzeitig zu dem Rinnenquerschnitt (Fig. 4 oder 5) gebogen. Wie Fig. 5 zeigt, können an den Biegekanten oder an anderen geeigneten Stellen Verdickungen b ■ vorgesehen sein.The intermediate profiles according to FIGS. 2 and 3 have in the middle a bulge α opposite the curved channel, the wall thickness of which is greater than that of the finished channel. These intermediate profiles are then stretched even further in the next passes of the rolling mill and at the same time bent to form the channel cross-section (Fig. 4 or 5). As FIG. 5 shows, thickenings b ■ can be provided at the bending edges or at other suitable locations.
Das Zwischenprofil kann natürlich auch mehrere Ausbauchungen α erhalten.The intermediate profile can of course also have several bulges α .
