"Vorrichtung zum Einformen von Bandmaterial""Device for molding strip material"

(Zusatz zu Patent ..., Patentanmeldung P 25 36 125o5)(Addition to patent ..., patent application P 25 36 125o5)

Gegenstand der Erfindung ist eine Vorrichtung zum Einformen von Bandmaterial gemäß Patent e.., Patentanmeldung P 25 36 125.5)·The subject of the invention is a device for molding strip material according to patent e .., patent application P 25 36 125.5) ·

Beim Einformen der Bänder nach obigem Patent»··, Patentanmeldung P 25 36 125<>5) hat es sich für verschiedene Wandstärken/Durchmesserverhältnisse herausgestellt, daß die Wand leicht nach innen einfällt. Obwohl dies für die Weiterverarbeitung zu Rundprofilen unerheblich ist, kann es bei der Herstellung von Profilrohren nachteilig sein.When molding the bands according to the above patent »··, patent application P 25 36 125 <> 5) it has been used for different wall thicknesses / diameter ratios found that the wall dips slightly inward. Although this is for further processing into round profiles is insignificant, it can be disadvantageous in the production of profile tubes.

Aufgabe der Erfindung ist es daher, ein Einfallen der Profilseiten beim Einformen zu vermeiden«,The object of the invention is therefore to prevent the profile sides from collapsing to be avoided when molding «,

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß die schräggestellten Walzen leicht konkav ausgebildet sind. Hierbei soll die Tiefe des Walzengrundes die mittlere Wand-To achieve this object, it is proposed according to the invention that the inclined rollers are designed to be slightly concave. Here, the depth of the bottom of the roller should correspond to the middle wall

Es zeigen:Show it:

Fig. 1 den ersten Satz Einformwalzen,Fig. 1 the first set of forming rollers,

Figo 2 die nach Figur 1 gezeigten Walzen in der nächsten Einformstufe,FIG. 2 shows the rollers shown in FIG. 1 in the next molding stage,

Fig. 3 das durch Mittelwalzen eingeformte Fünfkantprofil, Fig. 4 das fertige Fünfkantprofil in der Schweißstelle.3 shows the pentagonal profile formed by central rollers, FIG. 4 shows the finished pentagonal profile in the weld.

In den in Figo 1 und 2 gezeigten Einformgerüsten für das Band sind die aus Oberwalzen 2 und Unterwalzen 3 bestehenden Einformwalzen in breitem Abstand stufenlos horizontal verstellbar und die Oberwalzen zusätzlich höhenverstellbar angeordnet. Ferner sind die Einformwalzen an den Außenseiten zusätzlich mit schräggestellten leicht konkav ausgebildeten Walzen 4 versehen.In the molding stands for the strip shown in FIGS. 1 and 2, the molding rollers consisting of top rollers 2 and bottom rollers 3 are used Horizontally adjustable at a wide distance and the top rollers are also arranged to be height-adjustable. Furthermore, the forming rollers are additionally formed with slightly concave rollers 4 at an angle on the outer sides Mistake.

Fig. 3 zeigt die weitere Verformung mit schräg angeordneten ortsfesten leicht konkav ausgeführten Flachwalzen 5 und einer Mittelwalze 6O 3 shows the further deformation with inclined, stationary, slightly concave flat rollers 5 and a central roller 6 O

Die Endform des Profiles 8 wird in dem in Fig. 4 gezeigten Gerüst erzielt, in dem die für das jeweilige Gerüst erforderlichen Walzen, bestehend aus am Umfang des Profiles angreifenden angetriebenen oder antriebslosen verstellbaren leicht konkav ausgebildeten Flachwalzen 7 angeordnet sind·The final shape of the profile 8 is that shown in FIG Scaffolding achieved in which the necessary for the respective scaffolding Rollers, consisting of driven or non-driven, easily adjustable ones acting on the circumference of the profile concave flat rollers 7 are arranged
