Description
Die Erfindung bezieht sich auf einen Gewindeschneidsupport, insbesondere zum Schneiden von Gewinden, an deren Genauigkeit sehr hohe Ansprüche gestellt werden, darunter solchen, welche gegen hohen Druck ohne Verwendung von Padkmaterial eine metallische Dichtung herstellen sollen. Solche Gewinde müssen auf der Drehbank hergestellt werden.The invention relates to a thread cutting support, in particular for Cutting threads, the accuracy of which is very demanding, including those which are metallic against high pressure without the use of padk material To produce seal. Such threads must be made on the lathe.
ίο Es ist zwar bekannt, Drehbanksupporte als Gewindeschneidkluppen mit im Kreis ange-' ordneten Gewindeschneidbacken auszubilden, doch lassen sich diese ihrer 'kluppenartigen Wirkung wegen für das Schneiden von Prä-,zisionsgewinden nicht verwenden. An die Genauigkeit und Sauberkeit solcher Gewinde werden so hohe Ansprüche gestellt, daß nach dem Vorschneiden ein Schlichten der Gewindenut mittels im Support angeordneterίο Although it is known as lathe supports To form thread cutting brackets with thread cutting jaws arranged in a circle, however, because of their clip-like effect, they can be used for cutting precision threads do not use. The demands on the accuracy and cleanliness of such threads are so high that after the pre-cutting a finishing of the thread groove by means of arranged in the support
zo Einzelstrehler erfolgen muß. Auch die bekannten Drehstahlhalter mit übereinander angeordneten Werkzeugen lassen sich für das Schneiden von Gewinden nicht recht verwenden, und zwar deshalb nicht, weil des genauen Profils der Gewinde wegen die Gewindestrehler radial zum Werkstück hin sehr genau eingespannt werden müssen.zo single chaser must be done. Also the known turning tool holders with one above the other Tools cannot be used properly for cutting threads, and that is not because they are accurate Profile of the thread because of the thread chasers very precisely clamped radially towards the workpiece Need to become.
Die Erfindung zeichnet sich dadurch aus. daß der Support aus übereinander angeordneten Stahlhalterträgern mit einzelnen für sich einstellbaren, radial gerichteten Gewindestrehlern besteht, die in denselben Gewindenuten arbeiten. Auf diese Weise gelingt die Lösung der Aufgabe dadurch, daß die Gewindestrehler nacheinander zur Wirkung kommen, wobei sich die Werkzeuge so einstellen lassen, daß der erste Gewindestreh-'ler die Gewindenut schruppend, der nächste die Nut schlichtend erweitert.The invention is characterized by this. that the support from one above the other Steel holder beams with individually adjustable, radially directed thread chasers that work in the same thread grooves. In this way, the object is achieved in that the thread chasers come into effect one after the other, with the tools so let it be set that the first screwdriver roughing the thread groove, the next one expanding the groove.
Die Zeichnung veranschaulicht die Erfindung in einem Ausführungsbeispiel.The drawing illustrates the invention in one embodiment.
Auf Werkstück 1 soll Gewinde geschnitten werden. Der Gewindestrehler 3 ist auf bekannte Weise im Support 2 eingespannt. Ferner ist auf Support 2 der Stahlhalter 4 mit Gewindestrehler 5 angeordnet, welcher durch Schrauben zum Werkstück hin verschoben werden kann.Thread is to be cut on workpiece 1. The thread chaser 3 is known Way clamped in support 2. Furthermore, the steel holder 4 with thread chaser 5 is arranged on support 2, which through Screws can be moved towards the workpiece.
Da beide Gewindestrehler unabhängig voneinander einstellbar sind, bleibt, wenn der schruppend wirkende Gewindestrehler zwecks Schleif ens ausgespannt werden muß, die Einstellung des die Gewindenut schlichtenden Gewindestrehlers zum Werkstück hin erhalten. Die Leistung der Drehbank wird beim Gewindeschneiden durch diese Einrichtung verdoppelt.Since both thread chasers can be set independently of each other, remains when the roughing thread chasers must be unclamped for the purpose of grinding, the setting of the thread chaser finishing the thread groove towards the workpiece. The lathe's performance when tapping is provided by this facility doubled.
Die Einrichtung läßt sich auch für die Herstellung von Innengewinden ausführen.The device can also be used for the production of internal threads.
