Description

Verfahren und Vorrichtung zur Vorbehandlung von Metallbändern, die insbesondere als Bandrollen in Werkzeugen nach Patent 339359 Verwendung finden. Bei den in Werkzeuge nach Patent 339359 einzulegenden Metallbandrollen, aus welchen Rohre für elektrische Leitungen. hergestellt werden, hat sich der Übelstand gezeigt, daß bei Wicklung solcher Rollen, die etwa 2o m Metallband auf kleinem Wicklungsradius enthalten, durch Abwickeln von einer großen etwa 5oo in Metallband enthaltenden Rolle, zahlreiche kleine Knickstellen auftreten, die bei Herstellung des Metallrohres mit Hilfe des Werkzeuges störend wirken, in fertigen Rohren leicht Brüche erzeugen und namentlich bei Abbiegungen des Rohres Ausbauchungen oder sogar ein Platzen des Rohres herbeiführen.Method and device for the pretreatment of metal strips which in particular as tape rolls in tools according to patent 339359 use. In the case of the metal tape rolls to be inserted in tools according to patent 339359, from which Pipes for electric lines. are made, the evil has shown, that when winding such roles, the approximately 2o m metal tape on a small winding radius contained by unwinding a large one containing about 500 in metal tape Role, numerous small kinks that occur during the manufacture of the metal pipe with the help of the tool have a disruptive effect, easily create breaks in finished pipes and especially when the pipe bends, bulges or even bursting of the Bring about the pipe.

ach eingehenden Versuchen hat sich nun gezeigt, daß diesem großen Mangel nur dadurch abgeholfen «-erden kann, daß man das Metallband vor der Wicklung zu einer kleinen 2o-m-Rolle vollständig gleichmäßig geschmeidig macht, indem man es durch geeignete Vorrichtungen in allen seinen Teilen gewissermaßen durchknetet oder mürbe macht.After thorough experiments it has now been shown that this great Deficiency can only be remedied by removing the metal band before winding To a small 2o-meter roll, smooth completely evenly by kneading it to a certain extent in all of its parts by means of suitable devices or crumbles.

Dieses Geschmeidigmachen erfolgt nun gemäß vorliegender Erfindung für beliebige Zwecke und insbesondere für Bandrollen, die in einem Werkzeug nach Patent 339359 #"erwendung finden, in der Weise, daß man das Metallband vor dem Aufwickeln zu kleinen Rollen mehrfach wellenförmig abbiegt. Das Abbiegen kann sowohl in der Längsrichtung wie auch in der Querrichtung des Bandes erfolgen, so daß gleichsam jedes kleins' e Teilchen des Bandes mürbe gemacht wird.This softening is now carried out in accordance with the present invention for any purpose and especially for tape rolls that in one Find the tool according to patent 339359 # "use, in such a way that you can the metal band before winding it up into small rolls, it bends in a wave shape several times. The turning can be done in the longitudinal direction as well as in the transverse direction of the belt, so that, as it were, every tiny part of the ribbon becomes crumbly.

Das mehr oder minder wellenförmige Vorbiegen des Bandes kann sowohl von Hand als wie auch in vollkommener Weise durch maschinelle Behandlung erfolgen.The more or less wave-shaped pre-bending of the tape can be both by hand as well as perfectly by machine treatment.

In Abb. i und 2 ist eine einfache Vorrichtung schematisch in einem Ausführungsbeispiel dargestellt, welches zur Ausübung des neuen Verfahrens dient. Durch diese Vorrichtung wird das wellenförmige Abbiegen des Bandes sowohl in der Längs- als auch in der Querrichtung bewirkt.In Fig. I and 2 a simple device is schematically in one Exemplary embodiment shown, which is used to carry out the new method. With this device, the wavy bending of the tape is both in the Caused longitudinally as well as in the transverse direction.

Das 'Metallband c wird von der großen Metallbandrolle b, die auf einem Kern a von verhältnismäßig großem Durchmesser aufgewickelt ist, abgewickelt und von dort durch Rollen d, e, f, g, h, die in einer Zickzacklinie gegeneinander versetzt angeordnet sind, durchgezogen, wobei diese Rollen zweckmäßig undrehbar auf ihren Achsen sitzen, so daß das Band c, auf den Rollen schleifend, in einer Wellenlinie zwischen diesen Rollen hindurchwandern muß.The 'metal strip c is unwound from the large metal strip roll b, which is wound on a core a of relatively large diameter, and from there pulled through by rolls d, e, f, g, h, which are arranged offset from one another in a zigzag line, These rollers are suitably seated non-rotatably on their axes, so that the belt c, dragging on the rollers, must travel in a wavy line between these rollers.

Die einzelnen Rollen kann man noch auf ihrer Oberfläche gewölbt ausbilden, wie Abb.2 erkennen läßt, so daß das Metallband c auch noch in der Querrichtung nach innen und außen wellenförmig abgebogen wird, je nachdem es beim Durchziehen an einer unteren oder oberen Rolle anliegt.The individual roles can still be curved on their surface, as can be seen in Fig.2, so that the metal strip c is also in the transverse direction inside and outside is bent in a wave shape, depending on it when pulling through one lower or upper roller.

Chne daß der Erfindungsgedanke verlassen .wird, können die Rollen natürlich auch drehbar auf ihre Achsen angeordnet sein. Die Rollen sind zweckmäßig in der Kreise ausgestattet, daß über eine Scheibe ein Überzug aus Leder oder ähnlichem Stoff gespannt wird.Before the inventive idea is abandoned, the roles can of course also be rotatably arranged on their axes. The roles are functional equipped in the circle that a cover of leather or the like over a disc Fabric is stretched.

Sofern dann der Lederbezug an der Arbeitsstelle der feststehenden Rollen abgenutzt ist, kann die Rolle um einen entsprechenden Winkel verstellt werden, damit die anderen Teile des Lederbelages auf den Umfang der Rolle zur wirksamen Arbeit herangezogen werden.If then the leather cover at the place of work of the fixed The roller is worn out, the roller can be adjusted by an appropriate angle, so that the other parts of the leather covering to the extent of the role to be effective Work.

Selbstverständlich kann man auch anstatt der Rollen auch einfache Ballen mit entsprechenden Überzügen verwenden, die im Sinne der beschriebenen Rollen gegeneinander eingestellt werden. Sobald das Metallband c die Rollen bis 1a verlassen hat, ist es so mürbe, daß es ohne Gefahr des Knickens auf eine Achse von kleinem Durchmesser i zu Metallrollen von 2o in Länge aufgespult werden kann.Of course, you can also use simple roles instead of roles Use bales with appropriate covers that are in accordance with the roles described can be adjusted against each other. As soon as the metal band c leave the rollers to 1a it is so brittle that it can be bent on an axis of a small size without danger of buckling Diameter i can be wound into metal rolls of 2o in length.

Die nach vorliegendem Verfahren und mit der vorliegenden Einrichtung behandelten Metallbänder lassen sich dann im weiteren in @@'erkzeiie nach Patent 339359 auch zu einwandfreien glatten 'Metallrohren ohne Knicksiellen ziehen.According to the present procedure and with the present facility Treated metal strips can then be further identified in @@ 'according to patent 339359 can also be used to produce perfectly smooth metal pipes without any dimples.

Bei dein dargestellten Schema sind fünf Rollen, die gegeneinander entsprechend versetzt sind, dargestellt. Selbstverständlich kann man eine beliebige andere Anzahl der vorstehenden Ausführungen anordnen.In your illustrated scheme there are five roles that are against each other are offset accordingly, shown. Of course you can do any arrange a different number of the above statements.
