Description
Gegenstand der Erfindung ist eine Vorrichtung zur Ausführung eines Verfahrens zur Herstellung von kegelförmig zugespitzten Holzschrauben mittels mehrerer Strehlstähle nach Patent 481 764, und das Wesen der Zusatzerfindung liegt darin, daß die die Halter der Strehlstähle tragenden drehbaren Zapfen je in einer zu den Zapfen exzentrisch angeordneten drehbaren Hülse oder in einem Schieber oder einem Hebel gelagert sind und durch Hebel, Zahnstangen o. dgl., welche von Kurvenbahnen, kegeligen Körpern,, Exzentern oder Schrauben gesteuert werden, derart bewegt werden, daß die Strehlstähle das gewünschte Schraubenprofil schneiden.The invention relates to an apparatus for carrying out a method for Manufacture of conically tapered wood screws using several chasing steels according to patent 481,764, and the essence of the additional invention is that the holders of the rotatable pins carrying chasing steels each in one arranged eccentrically to the pin rotatable sleeve or are mounted in a slide or a lever and by levers, racks or the like. Which of Cam tracks, conical bodies, eccentrics or screws are controlled in such a way ensure that the chasing steels cut the desired screw profile.
Die Vorrichtung entsprechend der Zusatzerfindung zeichnet sich durch ihren einfachen und gedrängten Aufbau aus.The device according to the additional invention is characterized by its simple and crowded construction.
Die Erfindung ist in einer Ausführungs-The invention is in one embodiment
ao form beispielsweise auf der Zeichnung dargestellt, auf derao form, for example, shown on the drawing, on the
Abb. ι die Vorrichtung schematisch mitFig. Ι the device schematically with
einem Strehlstahl in mehreren Stellungen, Abb. 2 einen Stahlhalter in Arbeitslage in
der Längsrichtung des Werkstückes und
Abb. 3 eine Einzelheit zeigt.
Die Stahlhalter 2 mit ihren Strehlstählen 3 werden von drehbaren Zapfen 4 getragen, die
in je einer exzentrisch zu den Zapfen angeordneten drehbaren Hülse S gelagert sind.
Letztere ist ihrerseits in einem in geeigneter Weise verschiebbaren Rahmen 6 oder in einem
anderen für den beabsichtigten Zweck verwendbaren Maschinenteil gelagert.a steel in several positions, Fig. 2 a steel holder in the working position in the longitudinal direction of the workpiece and
Fig. 3 shows a detail.
The steel holders 2 with their steel bars 3 are carried by rotatable pins 4, which are each mounted in a rotatable sleeve S arranged eccentrically to the pins. The latter is in turn stored in a frame 6 that can be displaced in a suitable manner or in another machine part that can be used for the intended purpose.
Zur Drehung der Zapfen 4 sind diese mit Hebeln 7 versehen, die mit Lenkern 8 oder anderen Hilfsmitteln verbunden sind, die, um die erforderliche Bewegung der Strehlstähle zu erzielen, von Kurvenschlitzen, kegeligen Körpern, Exzentern, Schrauben o. dgl. (inTo rotate the pin 4, these are provided with levers 7 with links 8 or Other aids are connected to the necessary movement of the steel bars to achieve, of curved slots, conical bodies, eccentrics, screws or the like (in
der Zeichnung nicht gezeigt) gesteuert werden. Zwecks Drehung der exzentrischen Hülsen S, durch die die Strehlstähle dem Werkstück genähert oder von diesem entfernt werden, sind diese in geeigneter Weiäe mit Hebein 9 versehen, die mit Lenkern io gelenkig verbunden sind, die ihrerseits wieder wie die Lenker 8 durch Kurvenschlitze, kegelförmige Körper, Exzenterscheiben, Schrauben o. dgl. gesteuert werden. Die Lenker 8 und io sowie die Hebel 7 und 9 können selbstverständlich auch durch unmittelbar eingreifende Zahnstangen o. dgl. ersetzt werden, ohne daß das Wesen der Erfindung verlassen wird.not shown in the drawing). For the purpose of rotating the eccentric sleeves S, by means of which the chasing steels are brought closer to or removed from the workpiece, are these in a suitable white with a lever 9 provided, which are articulated with handlebars io, which in turn like the Handlebar 8 through cam slots, conical bodies, eccentric disks, screws or the like. being controlled. The handlebars 8 and io and the levers 7 and 9 can of course can also be replaced by directly engaging racks or the like, without the Essence of the invention is abandoned.
Die Vorrichtung wird zweckmäßig derart ausgeführt, daß die Mittellinie der Zapfen 4 und die Schneiden der Stahle sich auf einander gegenüberliegenden Seiten der Mittellinie des Werkstückes befinden, damit die Spitze der Schraube die erwünschte Form erhalten kann.The device is expediently designed in such a way that the center line of the pin 4 and the cutting edges of the steels are on opposite sides of the center line of the Workpiece are located so that the tip of the screw can get the desired shape.
Hierbei können beim Gewindeschneiden an der Spitze die Schneiden zweier einander gegenüberliegender Schneidstähle sich kreuzen (vgl. den linken Teil der Abb. 1).Here, when thread cutting at the tip, the cutting edges of two can be mutually exclusive opposite cutting steels cross each other (see the left part of Fig. 1).
