Stielbefestigung von Werkzeugen, deren Stiel aus Metallrohr besteht.Handle attachment of tools, the handle of which is made of metal tubing.
Patentiert im Deutschen Reiche vom 2). Juli 1912 ab.Patented in the German Empire from 2). July 1912.
Die Erfindung ist auf eine Stielbefestigung von Werkzeugen gerichtet, deren Stiel aus Metallrohr besteht. Die Erfindung besteht darin, daß in eine in dem Werkzeugkopf vorgesehene endlose Nut durch hydraulischen Druck eine entsprechende Wulst des Werkzeugstieles eingepreßt wird.The invention is directed to a handle attachment of tools, the handle from Metal pipe is made. The invention consists in that in one provided in the tool head endless groove by hydraulic pressure a corresponding bead of the tool handle is pressed in.
Bei der in der Zeichnung dargestellten Ausführungsform der Befestigung ist α der aus ίο einem Metallrohr bestehende Stiel. In dem Werkzeugkopf b ist eine Nut c vorgesehen, in welche unter Anwendung großen hydraulischen Druckes der entsprechende Teil der Rohrwandung des Stieles in Form einer Wulst d eingepreßt wird. Zu diesem Zwecke ist es notwendig, das ganze Werkzeug mit dem Stiel in einer Matrize unterzubringen, welche das eine Ende des Stielrohres abschließt und das Aufreißen des Stieles durch den hydraulischen Druck verhindert.In the embodiment of the fastening shown in the drawing, α is the stem consisting of ίο a metal tube. A groove c is provided in the tool head b , into which the corresponding part of the tube wall of the handle in the form of a bead d is pressed using high hydraulic pressure. For this purpose, it is necessary to accommodate the entire tool with the handle in a die, which closes one end of the handle tube and prevents the handle from being torn open by the hydraulic pressure.
