Description
Rohrstoßbank Um den flotten Arbeitsgang bei Rohrstoßbänken zu fördern, wird erfindungsgemäß vorgeschlagen, den Vorschub des Werkstückes im Ziehbett durch die Ziehringe hindurch außer durch die Dornstange durch besondere, im Bereich des Ziehbettes liegende Treibrollen in der Weise durchzuführen, daß während des Rückhubes des Dorngestänges bzw. der Zahnstange in die Ausgangsstellung die Treibrollen allein das Werkstück durch die restlichen Ziehringe hindurch aus dem Bereich des Ziehbankbettes herausbewegen.Pipe push bench To promote the brisk work process with pipe push benches, is proposed according to the invention, the advance of the workpiece in the drawing bed the pull rings through except through the mandrel bar through special ones in the area of the Pull bed lying driving rollers to carry out in such a way that during the return stroke of the mandrel linkage or the rack in the starting position the drive rollers alone the workpiece through the remaining draw rings from the area of the draw bench bed move out.
Es ist zwar bekannt, im Ziehbett einer Stoßbank Rollenpaare anzuordnen, die entweder unangetrieben an Stelle von Ziehringen als formgebende Kaliber dienen oder als angetriebene Rollen unmittelbar Walzarbeit auf den Dorn leisten.Although it is known to arrange pairs of rollers in the draw bed of a push bench, which are either unpowered instead of drawing rings as the shaping caliber or perform rolling work directly on the mandrel as driven rollers.
Weiter ist es bekannt, im Ziehbett angetriebene Rollen anzuordnen, die, falls das Ziehbett nicht in seiner ganzen Länge zur Formarbeit benutzt wird, das Rohr aus dem Bereich des Ziehbettes lierausbewegen.It is also known to arrange driven rollers in the draw bed, which, if the pull bed is not used in its entire length for molding, Move the tube out of the area of the draw bed.
Erfindungsgemäß werden derartige Treibrollen verwendet, die den durch die Dornstange eingeleiteten Vorschub und das Hmdurchbewegen des Werkstückes durch dic letzten Ziehringe vollenden, so daß während der Zurücklegung der Endstrecke der Werkstückbewegung innerhalb des Ziehbettes das Dorngestänge bzw. die Zahnstange scholl in ihre Ausgangsstellung zurück und für den nächsten Arbeitsgang in Bereitschaft gebracht werden kann.According to the invention, such driving rollers are used, which by the feed initiated by the mandrel bar and the Hm-through movement of the workpiece Complete the last pull rings so that during the covering of the final distance the workpiece movement within the drawing bed, the mandrel linkage or the rack scholl back to its starting position and ready for the next step can be brought.
Es empfiehlt sich, die Ausbildung so zu treffen, daß die Treibrollen den vom Dmnschaff inzwischen gelösten Dorn unmittelbar vorbringen. Die Treibrallen werden zweckmäßig mit Einzelantrieben (Elektroantrieben) versehen, und außerdem werden dieselben im Ziehbett ortsveränderlich ange-or dnet, um sie so der jeweiligen für die einzelnen Rohrabmessungen ,erforderlichen wirksamen Länge des Ziehbettes in ihrer Lage anzupassen. Es ist zweckmäßig, die im Ziehbett vorhandenen Befestigungsnuten für die Ziehringe zum Einsetzen der Antriebe mit den Rollen nutzbar zu machen.It is advisable to make the training so that the drive rollers bring forward the thorn, which has meanwhile been loosened by the Dmnschaff. The driving claws are expediently provided with individual drives (electric drives), and moreover The same are arranged in a movable manner in the pull-out bed in order to make them more specific to each other for the individual pipe dimensions, required effective length of the drawing bed adapt in their location. It is useful to use the fastening grooves in the pull bed to make the pull rings usable for inserting the drives with the rollers.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.
In dieser bezeichnet i das gezogene und sich auf dein Dorn ? befindliche Rohr. Mit 3 sind die Ziehringe des mit 3' bezeichneten Ziehbettes angedeutet. Der Dornschaft q. ist in bekannter Weise mit der Zahilstange 5 gekuppelt, deren Antriebsritz@el durch 6 angedeutet ist.In this i referred to the drawn and up on your thorn? located Pipe. With 3 the pull rings of the draw bed designated with 3 'are indicated. Of the Thorn shaft q. is coupled in a known manner with the number rod 5, the drive scoring @ el is indicated by 6.
Im Ausführungsbeispiel ist der letzte Ring mit 7 bezeichnet. Diesem vorgeordnet sind die in einem einsetzbaren Rahmen befindlichen Treibrollen i o. Hinter dem Ziehring befindet sich ein weiteres mit io' bezeichnetes Treibrollenpaar. 8 sind n -ormale, im Ziehbett befindliche Förderrollen. Durch 9. ist eine Rolle eines sich dem Ziehbett anschließenden Rollganges bezeichriet.In the exemplary embodiment, the last ring is designated by 7. This one upstream are the driving rollers i o located in an insertable frame. Behind the drawing ring there is another pair of drive rollers labeled io '. 8 are normal conveyor rollers located in the drawing bed. By 9th is a role of a roller table adjoining the draw bed.
Das Rohr i ist nach der Zeichnung über den Dorn a mittels des Dornschaftes q. durch die Zugorgane 3 ausgestreckt worden.The tube i is according to the drawing over the mandrel a by means of the mandrel shaft q. has been stretched out by the pulling members 3.
Kurz bevor das Rohr durch den letzten Ziehring gezogen wird, ist es nach der Erfindung möglich, daß Zahnstange 5 und die Dornstange q. bereits in die Ausgangsstellung zurückgehen können, da der Dorn 2 mit dem auf ihm sitzenden Rohr i vermittels der im Ziehbett angeordneten Treibrollen io und W-, und auch der Förderrollen 8 durch den letzten. Ziehring hindurch aus dem Bereich des @ie1,"w:@ebettes gebracht und an den Rollgang 9 abg.cf@' geben werden kann. Die Treibrollen io sind so ausgebildet und angeordnet, daß sie den Dorn beim weiteren Vortrieb fest erfassen.Just before the pipe is pulled through the last pull ring, it is According to the invention possible that rack 5 and the Mandrel bar q. can already go back to the starting position, since the mandrel 2 with the on it seated tube i by means of the drive rollers arranged in the drawing bed io and W-, and also the conveyor rollers 8 through the last. Pull ring out of the area des @ ie1, "w: @ebetten and can be given to roller table 9 abg.cf @ '. The drive rollers io are designed and arranged so that they the mandrel when further Record propulsion firmly.
