Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines schraubenlinienförmig profilierten Hohlkörpers aus einem metallischen Werkstoff, bei dem ein drehbar gelagertes, schräg geschnittene Nuten aufweisendes Ziehwerkzeug auf einen kalten Hohlkörper mit glatter Zylinderwand zur Einwirkung gebracht und der Querschnitt des Hohlkörpers dabei verringert wird. Um ein solches Verfahren und auch eine Vorrichtung zu schaffen, mit dem bzw. der ein eine über die gesamte Wanddicke ver­ drallte Profilierung aufweisendes, dünnwandiges Rohr beliebiger Länge einfach und kostengünstig hergestellt werden kann, wird vorgeschlagen, daß zur Herstellung eines im Querschnitt wellenförmig über die gesamte Wanddicke profilierten Rohres ein Glattrohr mit einem s/D-Verhältnis im Bereich von 0,015 bis 0,080 durch den drehbar gelagerten, schräg geschnittene Nuten aufweisenden Ziehring auf einen kleineren Durchmesser gezogen wird, wobei bei nahezu unveränderter Wanddicke die Länge der Hüllkurve des Außenprofils des profilierten Rohres annähernd gleich dem Umfang des Glattrohres ist. The invention relates to a method for manufacturing a helically profiled hollow body made of a metallic material, one of which is rotatable stored, diagonally cut grooves Drawing tool on a cold hollow body with smoother Cylinder wall and cross section of the hollow body is reduced. To one Method and also to create a device with the one or a ver over the entire wall thickness twisted profiling, thin-walled tube any length easily and inexpensively manufactured can be proposed to manufacture one wavy in cross-section over the entire Wall thickness profiled tube a smooth tube with a s / D ratio in the range of 0.015 to 0.080 by the rotatably mounted, with diagonally cut grooves Pulling ring is drawn to a smaller diameter, with almost unchanged wall thickness the length of the Envelope curve of the outer profile of the profiled pipe is approximately equal to the circumference of the smooth tube.
