Description

Verfahren zur Herstellung von U-förmigen Profilen mit hohen Flanschen Das Walzen von U-förmigen Profilen mit hohen Flanschen wird bei einem gegebenen Walzwerk unmöglich, weil die Kalibereinschnitte zu tief und dadurch die Walzen zu stark geschwächt werden. Man hat sich deshalb in der Weise geholfen, daß man die U-förmigen Profile aufbog. Dadurch wird aber die Breite des Profils erheblich vergrößert, so daß weniger Stiche (oder Kaliber) auf ein Walzgerüst gehen. Infolgedessen wird das Verfahren unwirtschaftlich. Nach der Erfindung soll das Walzen derartiger Profile dadurch ermöglicht werden, daß die Schwerpunktachse der Vorprofile durch Einziehen des Rückens verlagert wird, und zwar unter Beibehaltung der größten Profilbreite. Ein solches Einziehen des Rückens ist zwar bereits benutzt worden, jedoch nur, um auf diese Weise unterschnittene Teile herzustellen.Process for the production of U-shaped profiles with high flanges The rolling of U-shaped profiles with high flanges is at a given Rolling mill impossible because the groove cuts too deep and the rollers closed be severely weakened. One has therefore helped oneself in such a way that one has the U-shaped profiles bent open. However, this increases the width of the profile considerably, so that fewer passes (or calibres) go on a roll stand. As a result, will the process is uneconomical. According to the invention, the rolling of such profiles are made possible by the fact that the center of gravity axis of the preliminary profiles is drawn in of the back is shifted while maintaining the largest profile width. Such a retraction of the back has already been used, but only to to produce undercut parts in this way.

In der Zeichnung ist a ein U-eisenförmiges Profil, wie es nach dem bisherigen Verfahren gewalzt wird-. Die zugehörige Schwerpunktachse ist x-x. Nach der Erfindung wird das Profil, wie aus der Zeichnung b ersichtlich, bei c eingezogen, so daß sich die Schwerpunktachse bis nach y-y verlagert. Um den Abstand zwischen x-x und y-y hebt sich das Profil aus der Unterwalze in die Oberwalze. Im letzten Stich, der nur wenig Druck hat, wird dann das Profil mit seiner richtigen Schwerpunktachse in die Walzen eingeschnitten.In the drawing, a is a U-shaped profile as it is after the previous process is rolled-. The associated center of gravity is x-x. To of the invention, the profile, as can be seen from drawing b, is drawn in at c, so that the center of gravity shifts to y-y. To get the distance between x-x and y-y the profile is lifted from the lower roller into the upper roller. In the last Stitch that has only little pressure then becomes the profile with its correct center of gravity cut into the rollers.

Dieses Prinzip läßt sich bei den verschiedensten Walzarten mit Vorteil anwenden.This principle can be used to advantage in a wide variety of rolling types use.
