Description

Kunststoff-Folie für das Tiefziehen von Blech Nach einem älteren Vorschlag wird beim Tiefziehen von Blech als Schmiermittel eine lose aufgelegte Kunststoff-Folie aus Polyvinylchlorid od. dgl. benutzt.Plastic film for deep drawing sheet metal Based on an older proposal When deep drawing sheet metal, a loosely applied plastic film is used as a lubricant Made of polyvinyl chloride or the like. Used.

Gegenstand der Erfindung ist die Anwendung einer auf diesen Zweck besonders abgestimmten Kunststoff-Folie-, nämlich einer aus einem Polyvinylehlorid niedrigen K-Wertes bestehenden weichmacherfreien und durch thennische Nachbehandlung vergüteten Hartfohe. Der K-Wert charakterisiert den Polymerisationsgrad und steht mit der Viskosität in Zusammenhang. Als niederer K-Wert im Sinne der Erfindung gilt ein solcher des unteren Bereichs der K-Wert-Reihe, insbesondere der Wert 50. Die Einlegefolie der Erfindung wird in üblicher Weise auf dem Kalander hergestellt und durch eine thermische Nachbehandlung bei etwa 200' C vergütet.The subject of the invention is the use of a plastic film specially tailored to this purpose, namely a plasticizer-free rigid film made from a polyvinyl chloride with a low K value and tempered by thermal aftertreatment. The K value characterizes the degree of polymerization and is related to the viscosity. As a low K-value within the meaning of the invention, in particular the value 50. The insert sheet of the invention is prepared in a conventional manner on the calender and tempered by a thermal treatment at about 200 'C applies such a the lower range of the K value range, .

Es wurde festgestellt, daß gerade eine solche Folie in besonders glücklicher Form allen Erfordernissen genügt, die eine der zu schmierenden Fläche lose aufgelegte Folie beim Tiefziehen von Blech, insbesondere Stahlblech, befriedigen muß. Sie schützt die Ziehmatrize und erhöht so bedeutend die Lebensdauer dieses kostspieligen Werkzeuges; sie folgt einwandfrei dem Ziehvorgang des Blechzuschnittes; sie bewirkt, daß die von ihr abgedeckte Außenseite des Ziehlings besonders glatt und sauber ausfällt, so daß für viele Verwendungszwecke eine Nachbearbeitung dieser Außenseite sich erübrigt; sie hat außerdem den durchaus überraschenden Effekt, daß bei ihrer Anwendung im einmaligen Ziehvorgang eine wesentlich größere Ziehtiefe erreichbar ist als bisher.It was found that just such a slide is particularly fortunate Shape meets all requirements that one loosely placed on the surface to be lubricated Foil when deep drawing sheet metal, in particular sheet steel, must satisfy. Protects you the drawing die and thus significantly increases the service life of this expensive tool; it perfectly follows the drawing process of the sheet metal blank; it causes the the outside of the specimen covered by it is particularly smooth and clean, so that post-processing of this outside is unnecessary for many purposes; it also has the surprising effect that when used in one-time drawing process a much greater drawing depth can be achieved than before.

Der erfindungsgemäße K-Wert des Polyvinylchlorids für die Folie ist so gewählt, daß sie bei der beim Tiefziehen von Metall entwickelten verhältnismäßig geringen Wärme von etwa 70 bis 901 C ausreichend plastisch wird, um sich gleichmäßig verformen zu lassen.The K value according to the invention of the polyvinyl chloride for the film is chosen so that it becomes sufficiently plastic at the relatively low heat of about 70 to 901 ° C. developed during deep drawing of metal to be able to be deformed uniformly.
