Description

Es sind durch Patent 708 o57 Gewindewalzmaschinen zur Herstellung von Außengewinden auf Bolzen u. dgl. bekanntgeworden, bei denen zwei mit Gewindeprofilen gleicher Steigung versehene Walzen oder Rollen in gleicher Drehrichtung angetrieben werden und beim Arbeitsgang der Achsabstand der beiden Walzen bis zur Erreichung der erforderlichen Gewindetiefe verringert wird. Zur sicheren Abstützung des beim Arbeitsvorgang zwischen den beiden Walzen liegenden Werkstückes hat man zwischen den Walzen ein geeignetes Stützlager vorgesehen, welches auch bereits pendelnd ausgebildet wurde, damit sich das aufliegende Werkstück dem sich allmählich verringernden Abstand der Walzen anpassen kann.There are by patent 708 o57 thread rolling machines for manufacturing of external threads on bolts and the like. Become known in which two with thread profiles Rollers or rollers provided with the same pitch are driven in the same direction of rotation and during the operation the center distance of the two rollers until it is reached the required thread depth is reduced. For the secure support of the Work process between the two rollers lying workpiece one has between A suitable support bearing is provided for the rollers, which is also already designed to oscillate so that the workpiece on top of the gradually decreasing distance the reels can adjust.

Für Werkstücke größerer Länge, z. B. für Stehbolzen, welche an den beiden Bolzenköpfen gleichzeitig mit Gewinden versehen werden sollen, muß entsprechend der erforderlichen großen Achslänge der beiden Walzen auch das Stützlager für das U'erl:stücl: eine entsprechende Länge aufweisen.For workpieces of greater length, e.g. B. for studs attached to the both bolt heads are to be provided with threads at the same time, must accordingly the required large axis length of the two rollers also the support bearing for the U'erl: stücl: have a corresponding length.

Zur sicheren und sich dem Druck und der Verschiebung der Walzen anpassenden Abstützung des beim Arbeitsgang zwischen den Walzenpaaren liegenden Werkstückes ist außer der bisherigen pendelnden Ausbildung des Stützlagers erfindungsgemäß auch gleichzeitig die unmittelbare Auflage für das Werkstück um eine Achse senkrecht zur Pendelachse schwenkbar angeordnet, wobei die Sch-,venkbarkeit der Auflage durch in Nuten laufende Anschlagstifte begrenzt ist. Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstands, wobei darstellen: Abb. r eine Seitenansicht des neuen Stützlagers, Abb. 2 eine Vorderansicht desselben.For safe and adaptable to the pressure and the displacement of the rollers Support of the workpiece lying between the roller pairs during the work cycle is in addition to the previous oscillating design of the support bearing according to the invention at the same time the immediate support for the workpiece about an axis perpendicular arranged pivotably to the pendulum axis, whereby the pivotability of the support by stop pins running in grooves is limited. The drawing shows an embodiment of the subject matter of the invention, wherein: Fig. r shows a side view of the new Support bearing, Fig. 2 is a front view of the same.

Es bezeichnet s das in an sich bekannter Weise um die Zapfen zr pendelnd angeordnete Stützlager, dessen obere Auflage s' für dar Werkstück t erfindungsgemäß um eine Achse v senkrecht zur Pendelachse schwenkbar ist, wobei die Sch-,venkbarkeit durch in Nuten x laufende Anschlagstifte w eine Begrenzung erfährt.It denotes s that oscillating around the pin zr in a manner known per se arranged support bearing, the upper support s' for the workpiece t according to the invention is pivotable about an axis v perpendicular to the pendulum axis, the pivotability is limited by stop pins w running in grooves x.

Die obere Auflagefläche s=' des Stützlagers wird zweckmäßig entsprechend dem kreisförmigen Querschnitt des Bolzenkörpers hohl ausgekehlt.The upper bearing surface s = 'of the support bearing is expediently corresponding the circular cross-section of the bolt body is hollowed out.
