EMI1.1
Die Erfindung hat eine Einrichtung zur Herstellung des Sehaft-und Spitzengewindes von Holzschrauben mittels mehrschneidiger Stähle. die entlang dem Werkstück geführt werden, zum Gegenstand. Sie besteht im wesentlichen darin. dass zwei oder mehrere um den Umfang des Werkstückes verteilte Stähle durch Führungen geführt sind. die beim Gewindeschneiden zusammen mit den Stählen in der Längsrichtung des Werkstüekes verschoben werden und eine solche Form aufweisen, dass die Schneidkanten der Stähle beim Schneiden des Gewindes an der Schraubenspitze geneigt zueinander und zur Sehraubenaehse gerichtet sind und sodann zum Schneiden des Gewindes am Schraubenschafte allmählich in eine zueinander und zur Schraubenachse parallele Lage versehwenkt werden.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht. Fig. 1 zeigt den Gewindeschneidkopf in axialer Richtung gesehen und Fisr. 2 teilweise im Schnitt durch die Drehachse des Werkstückes, wobei die Schneidstähle jene Lage einnehmen. die erforderlich ist, um die Spitze des Werkstückes mit Gewinde zu versehen. Fig. 3 und 4 zeigen die Stellungen der Stähle bei fortge- schrittenem Gewindesehneiden und bei fertiggeschnittenem Gewinde.
Der Gewindeschneidkopf 1 erhält z. B. durch eine Kurvenführung eine Axialbewegung. die der Steigung des herzustellenden Gewindes entspricht. Die Schneidstähle : 2 sind in kreisförmigen Nuten 3

so gewählt ist. dass die Schraube die gewünschte Form erhält. Bei fortgesetztem Gewindeschneiden nehmen die Schneidstähle die Stellung nach Fig. 3 ein und werden sodann zwecks Fertigschneiden des

EMI1.1
The invention has a device for producing the shaft thread and point thread of wood screws by means of multi-edged steels. that are guided along the workpiece, to the object. It essentially consists in this. that two or more steels distributed around the circumference of the workpiece are guided by guides. which are shifted together with the steels in the longitudinal direction of the workpiece during thread cutting and have such a shape that the cutting edges of the steels are inclined towards each other and towards the very screw shaft when the thread is cut on the screw tip and then gradually into one to cut the thread on the screw shaft be pivoted to each other and to the screw axis parallel position.
An exemplary embodiment of the invention is illustrated in the drawing. Fig. 1 shows the thread cutting head seen in the axial direction and Fisr. 2 partially in section through the axis of rotation of the workpiece, the cutting steels occupying that position. which is required to provide the tip of the workpiece with a thread. 3 and 4 show the positions of the steels with advanced thread cutting and with a finished thread.
The thread cutting head 1 receives z. B. an axial movement by a curve guide. which corresponds to the pitch of the thread to be produced. The cutting steels: 2 are in circular grooves 3

is so chosen. that the screw has the desired shape. With continued thread cutting, the cutting steels assume the position according to FIG. 3 and are then used for the purpose of finishing the
