Abstract

The lathe for pre-turning rods and tubes has stripping tools (12) on rod tool carriers (11), with a number of tool rod carriers (11) sliding in grooves in a radial array in a rotating disc (10). The disc (10) is fixed to a hollow shaft (18) which rotates in its mounting on the machine frame (17). A cone bush (13) fixed to the hollow shaft, rotates with it, so that as it advances the contact surfaces of the bush act on angled surfaces (11a) of the carrier rods (11) to give a radial movement to them. The cone bush is held in a push bush, mounted without rotation in the machine frame, to transmit the action of a push mechanism (14a) to the cone bush. A hydraulic clamping sleeve (15) is inserted between the push bush (14) and a cylindrical surface (17a) of the machine housing (17). Its hydraulic force is set and controlled to give the machine a low tolerance operation without play, with adjustment of the required play between the push bush and the clamping sleeve.

Description

Eine Maschine nach der Erfindung hat die Aufgabe, Rohre und Stangen aus Metall bei höchster Leistung toleranzfrei, also mit höchster Präzision zu schälen.A machine according to the invention has the task of pipes and Poles made of metal with maximum performance tolerance-free peel with maximum precision.

Diese Aufgabe wird durch eine Maschine mit den Merkmalen nach dem Patentanspruch gelöst.This task is performed by a machine with the characteristics solved according to the claim.

Mit dieser Maschine ist es möglich, ein axial durchlaufendes Rohr oder eine Stange mit Hilfe mehrerer sich drehender Schälwerkzeuge außen zu schälen. Dabei können die radial angeordneten Werkzeugträger in einer zentrischen Bewegung so gesteuert werden, daß unter Berücksichtigung des Verschleißes ein gleichmäßiges Abschälen gewährleistet ist. Der gesamte Schälmechanismus wird beeinflußt durch den Druck einer sich am Maschinengestell abstützenden hydraulischen Klemmhülse, deren hydraulischer Druck so gesteuert wird, daß auch bei höchsten Schälleistungen Toleranzen minimal gehalten werden und ein spielfreies Schälen gewährleistet ist.With this machine it is possible to make an axially continuous Pipe or rod using several rotating ones Peel peeling tools on the outside. The radial arranged tool carrier in a central movement like this be controlled taking into account the Uniform peeling is guaranteed. The entire peeling mechanism is affected by the pressure a hydraulic one supported on the machine frame Clamping sleeve, the hydraulic pressure of which is controlled so that Tolerances are minimal even with the highest peeling performance are kept and a play-free peeling is guaranteed is.

Ein Ausführungsbeispiel der Erfindung wird im folgenden beschrieben, unter Bezugnahme auf die beiliegende Zeichnung, die in einem Schnitt den prinzipiellen Aufbau des Erfindungsgegenstandes zeigt.An embodiment of the invention is as follows described with reference to the accompanying drawing, which shows the basic structure of the Subject of the invention shows.

Es geht darum, ein Werkstück 1, nämlich ein Rohr oder eine Stange, das sich axial in Richtung des Pfeiles bewegt, an seiner Oberfläche zu schälen. Das Schälen erfolgt durch mehrere sich drehende Schälwerkzeuge 12. Es sind insgesamt vier Schälwerkzeuge vorgesehen, jeweils an einem stabförmigen Werkzeugträger 11. Die Werkzeugträger sind radial verschiebbar in Nuten einer Scheibe 10 angeordnet. Diese Scheibe ist festes Teil einer Hohlwelle 18, konzentrisch zum Werkstück 1 und angetrieben über einen Antrieb 18a. Mitdrehend ist eine Konusbüchse 13, die mit ihrer Konusfläche an Schrägflächen 11a der Werkzeugträger 11 anliegt. Wenn sich die Konusbüchse nach vorne verschiebt, erhalten sämtliche Werkzeugträger 11 und damit die Werkzeuge 12 eine Bewegung zum Zentrum hin. Durch diese Korrektur sollen Verschleißerscheinungen an den Schälwerkzeugen 12 ausgeglichen werden. Im übrigen kann durch den Verschub der Konusbüchse 13 auch die Spantiefe eingestellt werden.It is about peeling a workpiece 1 , namely a pipe or a rod, which moves axially in the direction of the arrow, on its surface. The peeling is carried out by a plurality of rotating peeling tools 12 . A total of four peeling tools are provided, each on a rod-shaped tool carrier 11 . The tool carriers are arranged radially displaceably in grooves in a disk 10 . This disc is a fixed part of a hollow shaft 18 , concentric to the workpiece 1 and driven by a drive 18 a. Is a co-rotating conical bushing 13 a of the tool holder 11 rests with its cone surface on inclined surfaces. 11 When the taper bush moves forward, all tool carriers 11 and thus the tools 12 are moved towards the center. This correction is intended to compensate for signs of wear on the peeling tools 12 . In addition, the cutting depth can also be adjusted by displacing the conical sleeve 13 .

Die Konusbüchse 13, die sich mit der Hohlwelle dreht, ist in einer unverdrehbaren Schubbüchse 14 gelagert, welche die Aufgabe hat, den für die Einstellung erforderlichen Schub auf die Konusbüchse 13 zu übertragen. Der Schubbüchse ist ein Schubmechanismus 14a zugeordnet, aufgenommen vom Maschinengehäuse 17.The cone bushing 13 , which rotates with the hollow shaft, is mounted in a non-rotatable thrust bushing 14 , which has the task of transmitting the thrust required for the adjustment to the cone bushing 13 . The thrust bush is assigned a thrust mechanism 14 a, received by the machine housing 17th

Zwischen der Schubbüchse 14 und einer zylindrischen Fläche 17a des Maschinengehäuses 17 ist eine an sich bekannte hydraulische Klemmhülse 15 eingesetzt, die über eine Ölleitung 16 gespeist wird. Durch die Beaufschlagung der Klemmhülse 15 wird ein Druck auf die Schubbüchse und somit auf das gesamte System ausgeübt. Der Druck wird während des Betriebes der Maschine so gesteuert, daß eine radiale Bewegung des gesamten Werkzeugsystems durch Klemmung der Hülse unterbunden wird, wodurch die Maßhaltigkeit des Schälgutes entscheidend verbessert wird. Zur Verstellung der Schubbüchse 14 wird der Druck vermindert und so ein geringes Spiel zwischen Schubbüchse 14 und Klemmhülse 15 erzeugt, wodurch ein axiales Verschieben der Schubbüchse 14 durch Schubmechanismus 14a möglich ist. Nach erfolgter Verstellung wird wieder (hydraulisch) geklemmt.Between the thrust sleeve 14 and a cylindrical surface 17 a of the machine housing 17 , a hydraulic clamping sleeve 15 known per se is inserted, which is fed via an oil line 16 . By acting on the clamping sleeve 15 , pressure is exerted on the push sleeve and thus on the entire system. The pressure is controlled during the operation of the machine so that radial movement of the entire tool system is prevented by clamping the sleeve, which decisively improves the dimensional accuracy of the peeling material. In order to adjust the thrust sleeve 14, the pressure is reduced, thus producing a slight clearance between the thrust bushing 14 and the clamping sleeve 15, thereby an axial displacement of the thrust sleeve 14 by the pusher mechanism 14 is a possible. After the adjustment has been made, the clamping is again (hydraulic).
