Abstract
Zum Verformen des Materials wie Hohlprofilen, Rohren usw. wird dieses in einen Aufnahmespalt zwischen einer Hohlform (40) mit Vertiefungen (35, 36, 37, 38, 39) einerseits und elasti schen Formstücken (12, 13, 14, 15, 16) andererseits ein gebracht. Die elastischen Formstücke sind in einem Ge häuse mit nichtelastischen Zwischenstücken (29, 30, 31, 32) geschichtet angeordnet, wobei lediglich eine Verfor mung in Richtung auf den Aufnahmespalt möglich ist. Durch Druck auf die Schichtung von elastischen Form stücken und nichtelastischen Zwischenstücken werden die elastischen Formstücke (12, 13, 14, 15, 16) in Richtung auf das zu verformende Material (33) elastisch verformt, wodurch das Material (33) bleibend in die Vertiefungen der Hohlform (40) hineinverformt wird. This is used to deform the material such as hollow profiles, pipes, etc. in a receiving gap between a hollow mold (40) Wells (35, 36, 37, 38, 39) on the one hand and elastic rule fittings (12, 13, 14, 15, 16) on the other brought. The elastic fittings are in one ge housing with non-elastic intermediate pieces (29, 30, 31, 32) arranged in layers, whereby only one Verfor tion in the direction of the receiving gap is possible. By pressing on the layering of elastic form pieces and non-elastic intermediate pieces elastic fittings (12, 13, 14, 15, 16) in the direction elastically deformed on the material to be deformed (33), whereby the material (33) remains in the recesses the hollow mold (40) is deformed.
Das Verfahren und die Vorrichtung sind insbesondere für das Verformen von rohrförmigem Material, beispielsweise zur Verbindung zwischen einem Rohr und ei nem stangenförmigen Endstück, anwendbar. The method and the device are especially for deforming tubular material, for example for the connection between a pipe and an egg rod-shaped end piece, applicable.
