Herstellung von Werkzeugen. Patentiert im Deutschen Reiche vom 8. Dezember 1920 ab.Manufacture of tools. Patented in the German Empire on December 8, 1920.
Die Erfindung bezieht sich auf die Herstellung von Werkzeugen mit Schneiden, die aus einer Hartlegierung bestehen, wobei die Schneide auf einen aus Stahl oder Eisen bestehenden Halter aufgeschmolzen wird. Erfindungsgemäß wird so verfahren, daß der Halter zur Aufnahme der geschmolzenen Hartlegierung mit einer Schutzform oder mit einer muldenartigen Aushöhlung versehen wird. NachThe invention relates to the manufacture of tools with cutting edges that consist of a hard alloy, with the cutting edge on one made of steel or iron Holder is melted. According to the invention, the procedure is such that the holder for receiving the molten hard alloy is provided with a protective form or with a trough-like cavity. To
!ο dem Erkalten der Legierung wird der Halter zwecks Freilegung und Gestaltung der harten Schneide abgeschliffen.! ο When the alloy has cooled down, the holder Ground down to expose and shape the hard cutting edge.
Man kann beispielsweise so verfahren, daß man die Halterstelle, an der die Schneide an-One can, for example, proceed in such a way that the holder point at which the cutting edge is
X5 gebracht werden soll, mit einer kleinen Höhlung versieht, in der man die Legierung zum Schmelzen bringt oder in die man die geschmolzene Legierung einträufelt. Statt dessen kann man auch einen Schutzring um die betreffende Halterstelle anbringen, der das Auseinanderfließen der Legierung verhütet und der sich entweder überhaupt nicht mit der Legierung vereinigt oder aber nach dem Einschmelzen der Legierung wieder durch Abfeilen, Abschleifen o. dgl. beseitigt wird.X 5 is to be brought, provided with a small cavity in which the alloy is melted or in which the molten alloy is instilled. Instead, a protective ring can be attached around the holder in question, which prevents the alloy from flowing apart and which either does not unite with the alloy at all or is removed again after the alloy has been melted down by filing, grinding or the like.
Besondere Bedeutung hat dies Verfahren für die Herstellung von Gesteinbohrerschneiden, und zwar sowohl für Bohrstangen als auch für die Herstellung der Zähne von Kernbohrern, ferner für dia Herstellung von Sägen für die Steinbearbeitung.This process is of particular importance for the production of rock drill bits, both for boring bars and for making the teeth of core drills, also for the manufacture of saws for stone processing.
