Description

Vorrichtung zum Ausschmieden der schraubenförmig gewundenen flachen Enden von Steinschrauben. Die Enden der Steinschraubenbolzen werden bisher von Hand geschmiedet. Die Erfindung betrifft eine Vorrichtung, mit welcher diese Arbeit in, besserer und wirtschaftlicherer Weise ausgeführt werden kann, indem in die Bolzenenden etwa schraubenförmige Nuten gepreßt werden. Diese von einem ungelernten Arbeiter bedienbare Vorrichtung ergibt etwa die zehnfache Leistung eines geübten Handschmiedes.Device for forging the helically wound flat Ends of stone screws. The ends of the stone screw bolts are so far by hand forged. The invention relates to a device with which this work in, a better and more economical way can be done by putting in the bolt ends approximately helical grooves are pressed. This by an unskilled worker operable device results in about ten times the performance of a skilled hand smith.

Vorrichtungen zum Einpressen von schraubenförmigen Nuten in Werkstücke sind an sich bekannt. Nach der Erfindung sind die Werkzeuge, welche die schraubenförmigen Nuten erzeugen, einander überkreuzend in der Vorrichtung angeordnet, und es wird das Werkstück diagonal zwischen sie eingeführt.Devices for pressing helical grooves into workpieces are known per se. According to the invention, the tools, which the helical Generate grooves, arranged crossing each other in the device, and it is the workpiece inserted diagonally between them.

In der Zeichnung ist eine Ausführungsform der Vorrichtung und eine mit ihr hergestellte Steinschraube dargestellt. Es zeigen Abb. z und 2 die beiden-Werkzeuge in zwei Ansichten, Abb. 3 eine Oberansicht der Werkzeuge mit eingelegtem Bolzen, Abb. 4 eine Längsansicht und Abb. 5 eine Stirnansicht einer fertigen Steinschraube.In the drawing is an embodiment of the device and a stone screw made with her is shown. Fig. Z and 2 show the two tools in two views, Fig. 3 a top view of the tools with inserted bolts, Fig. 4 is a longitudinal view and Fig. 5 is an end view of a finished stone screw.

Die beiden Werkzeuge a und b, die in eine Presse, z. B. eine Exzenterpresse eingesetzt werden, sind beide gleichartig .plattenförmig gestaltet und haben jede eine Ausnehmung c bzw. d, deren Ränder abgerundet und zweckmäßig halbkreisförmig gestaltet sind. Sie stehen gekreuzt zueinander, so daß die beiden Ausnehmungen beim Niedergang des Preßstempels ineinandergreifen. Zwischen diese Ausnehmungen wird in schräger Lage, etwa unter q.5° zu beiden Werkzeugen das Ende der Bolzen gelegt. Dieses wird daher bei der Pressung in die in Abb. q. dargestellte gewindeartige Form übergeführt. Die Bolzen werden kalt gepreßt. Der Preßstempel kann ständig auf und nieder gehen, und der Arbeiter nimmt nach jedem Hub die fertige Steinschraube heraus und legt ein neues Arbeitsstück ein.The two tools a and b, which are in a press, z. B. an eccentric press are used, both are designed in the same way .platteniform and each have a recess c or d, the edges of which are rounded and appropriately designed semicircular. They are crossed to one another, so that the two recesses interlock when the ram goes down. The end of the bolt is placed between these recesses in an inclined position, about 5 ° to both tools. This is therefore when pressed into the areas shown in Fig. Q. shown thread-like shape transferred. The bolts are cold pressed. The ram can go up and down constantly, and the worker takes out the finished stone screw after each stroke and inserts a new work piece.
