Description

Die Erfindung bezieht sich auf ein Verfahren zum Ziehen von Rohren im Hohl- oder Stopfenzug. Sie bezweckt, das Anschmieden von Ziehangeln und damit Material- und Zeitverlust einzusparen.The invention relates to a method for drawing pipes in the hollow or plug train. Its purpose is the forging of Ziehangeln and thus Save material and time wasted.

Erfindungsgemäß wird folgenderArbeitsvörgang angewendet: Ein kurzes Stück der Rohrluppe wird mittels einer Einstoßvorrichtung durch den Ziellri.ng gestoßen. Hinter dem Ziehring ist ein kurzer Dorn angeordnet, der an der Ziehzange abgestützt ist. Der Durchmesser dieses Dornes entspricht etwa dem Innendurchmesser des eingestoßenen Rohres. Der-Dorn ist nach der Einstoßseite zu schwach konisch verjüngt. Beim Durchstoßen der Rohrluppe durch den Ziehring wird das eingestoßene Rohrende auf den Dorn geschoben, und zwar nur so weit, daß es zugleich mit dem darin befindlichen Dorn von den Klemmbacken der Ziehzange sicher erfaßt werden 'kann.According to the invention, the following operation is used: A short one Piece of the tubular blank is pushed through the target line by means of a pushing device. A short mandrel is arranged behind the drawing ring and is supported on the drawing pliers is. The diameter of this mandrel corresponds approximately to the inner diameter of the inserted one Pipe. The mandrel is too weakly tapered towards the push-in side. When piercing the tube blank through the drawing ring, the pushed-in tube end is pushed onto the mandrel, and only so far that it is removed from the jaws at the same time as the mandrel located in it the pliers can be safely grasped '.

Bekannt ist ein Verfahren zur Verringerung des Durchmessers von hohlen Werkstücken ohne Anwendung von Ziehangeln, bei dem ein geradlinig hin und her bewegter Ziehring absatzweise über (las Wet'kstüak gezogen wird, das während des Ziehvorgangs in ein Klemmfutter eingespannt und zwischen den Zügen absatzweise vorgeschoben wird. Das bekannte Verfahren unterscheidet sieh iti wesentlichen PutIcten von denn Verfahren nach der Erfindung und ist mit den üblichen Einrichtungen einer Rohrziererei nicht auszuführen.A method for reducing the diameter of hollow is known Workpieces without the use of pulling levers, in which one is moved back and forth in a straight line Draw ring over (read Wet'kstüak is drawn, which is drawn during the drawing process clamped in a clamping chuck and pushed forward intermittently between the trains. The known method distinguishes itself from the method in its essential points according to the invention and is not with the usual facilities of a pipe decorating shop to execute.

In der Zeichnung ist eine Ausführungsform des Erfindungsgedankens für den Hohlzug schematisch wiedergegeben. Fig. t zeigt die Vorrichtung i» der Stellung unmittelbar vor Beginn, Fig. 2 während des Ziehvorgangs.In the drawing is an embodiment of the inventive concept shown schematically for the hollow train. Fig. T shows the device in the position immediately before the start, Fig. 2 during the drawing process.

Die zu behandelnde Ziehluppe i wird in die Spannbüchse 2 mittels Kniellehel 3 im Klemtnschlitten 4 f.estgeklemmt und in den Ziehring 5 eingestoßen. Beim weiteren Durchstoßen durch den Ziehring wird das eingestoßene Rohrende über den Dorn 6 geschoben. Der Dorn 6 ist hierbei gegen die Ziehzange 8 abgestützt. Die in der Ziehzange 8 angeordneten Ziehbacken 7 umfassen beim Ziehvorgang das Rohr i zugleich Mit dein Dorn 6.The drawing die to be treated i is placed in the clamping sleeve 2 by means of a Kniellehel 3 clamped in the clamping slide 4 and pushed into the drawing ring 5. With further After being pierced by the drawing ring, the inserted pipe end is pushed over the mandrel 6. The mandrel 6 is supported against the drawing pliers 8. The 8 arranged drawing jaws 7 include the tube i at the same time with your during the drawing process Mandrel 6.

Bei Anwendung des Verfahrens nach ,der Erfindung tritt nur mehr ein Bruchteil des Ziehendenabfalles auf, der beim Rohrziehen mit Ziehangeln üblich ist. Arbeits- und Energieaufwand für das Anschnnieden der Angelenden als gesonderten Arbeitsgang kommen in Fortfall, das Vorbereiten des Zangenendes erfolgt auf der Ziehbank selbst.When using the method according to the invention only occurs Fraction of the pulling waste that is common in pipe pulling with pulling handles. Work and energy expenditure for cutting the fishing ends as separate Steps are no longer applicable, the end of the pliers is prepared on the Draw bench itself.

PATENTANSPRUCH: Verfahren zum Ziehen i-oti Rollren nach dem Hohl- öder Stopfenziehverfahren dadurch gekennzeichnet, daß eilt kurzes Stück des Al ziehenden Rohres mittels eitler Einstoßvorriclitung durch den Ziehring gestoßen und gleichzeitig .über einen hinter (lern Ziehring angeordneten kurzen Dorn gescholten wird. worauf der Ziehvorgang in üblicher Form durch Einkfinken des Ziehliaketis in die Ziehkette durchgeführt wird derart, daß das eingestoßene Rohrstück mit dem in ihnt befindlichen kurzen Dorn in die Ziehbacken einl;ekletntnt wird. PATENT CLAIM: Method for pulling i-oti Rollren according to the hollow or plug pulling process, characterized in that a short piece of the pulling pipe rushes through the pulling ring by means of a push-in device and at the same time is scolded over a short mandrel arranged behind the pulling ring The drawing process is carried out in the usual way by inserting the drawing slide into the drawing chain in such a way that the pushed-in piece of pipe with the short mandrel located in it is clipped into the drawing jaws.
