Abstract

The tube has guide rings (1) and distance tubes (3) made from diverse materials, where the guide rings are provided with a chamfer that allows feedthrough of the material. A standard base tube (2) is fastened to a machine by a flange (7). The guide rings with associated distances are attached in the base tube and fastened with a screw plug (5).

Description

In Drehmaschinen mit Spannzangen- bzw. Dreibackenfutter und Hohlspannzylinder ist es üblich längere Materialstücke einzuspannen (Arbeiten von der Stange/Lademagazin). Zur zentrischen Führung dieser Materialstücke werden üblicherweise sog. ”Zugrohre” verwendet. Das Zugrohr hat die Aufgabe, den Durchmesserunterschied des Rohmaterials zum Hohlspannzylinder auszugleichen, wodurch eine möglichst unwuchtfreie zentrische Führung im Spannzylinder gewährleistet wird.In Lathes with collet or jaw chuck and hollow clamping cylinder It is usual to clamp longer pieces of material (Work from the pole / loading magazine). For the centric leadership of this material pieces become common so-called "draft tubes" used. The draft tube has the task of the diameter difference of the raw material to compensate for the hollow clamping cylinder, whereby a possible unbalanced centric guidance guaranteed in the clamping cylinder becomes.

Zu diesem Zweck ist eigentlich für jeden Rohteildurchmesser ein eigenes Zugrohr erforderlich, wodurch erhebliche Kosten entstehen.To this purpose is actually for each Rohteildurchmesser own draft tube required, which considerable costs arise.

Der Erfindung liegt die Idee zu Grunde, mit einem Baukastensystem durch Austausch von Führungsringen [Nr. 1] jeden gewünschten Durchmesser darstellen zu können.The invention is based on the idea of using a modular system by exchanging guide rings [No. 1 ] to represent any desired diameter.

Dazu benötigt man, je nach Rohteildurchmesser und Hohlzylinderlänge zwischen drei und sechs Führungsringe.To needed one, depending on Rohteildurchmesser and hollow cylinder length between three and six guide rings.

Dies wird durch ein Standard Grundrohr [Nr. 2] ermöglicht, welches der jeweiligen Maschine angepasst ist und über den Flansch [Nr. 7] in dieser befestigt wird.This is done by a standard base tube [No. 2 ], which is adapted to the respective machine and can be reached via the flange [no. 7 ] is fixed in this.

In diesem Grundrohr werden mehrere Führungsringe, mit den zugehörigen Distanzen [Nr. 3] eingebracht und mit der Verschlussschraube [Nr. 5] befestigt. Dazu kann es hilfreich sein, einen Distanzring [Nr. 4] zu verwenden.In this basic pipe several guide rings, with the corresponding distances [No. 3 ] and with the screw plug [no. 5 ] attached. It may be helpful to use a spacer ring [No. 4 ] to use.

Um das einschieben des Materials zu vereinfachen, ist es sinnvoll an den Führungsringen Einfädelungsfasen anzubringen.Around It is useful to simplify the insertion of the material the guide rings Einfädelungsfasen to install.
