Description

Die vorliegende Erfindung bezieht sich auf ein Werkzeug zum Schaben von Flächen, insbesondere der Gleitflächen von Lagern, mittels welchem man auf die zu bearbeitende Fläche eine schälende Wirkung ausüben kann. Zur Anpassung an die wechselnde Härte des zu bearbeitenden Materials wird man an dem einen Werkzeug mehrere Schneidkanten anordnen und deren Schnittwinkel abstufen, soThe present invention relates to a tool for scraping surfaces, in particular the sliding surfaces of bearings, by means of which one can access the Surface can exert a peeling effect. To adapt to the changing hardness of the The material to be processed will have several cutting edges arranged on one tool and graduate their cutting angle, see above

ίο daß für jede Materialbeschaffenheit je eine Schneidkante mit entsprechendem Schnittwinkel vorhanden ist. Hinter der Schneidkante und parallel zu derselben ist ein Wulst angeordnet, der als Auflage zur Sicherung des Schnittwinkels beim Schaben dient.ίο that one for each material quality There is a cutting edge with a corresponding cutting angle. Behind the cutting edge and parallel to the same a bead is arranged as a support for securing the Cutting angle when scraping is used.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in zwei zueinander senkrechten Ansichten und .einem Querschnitt dargestellt. Das Werkzeug zeigtIn the drawing, an embodiment of the subject invention is in two to each other vertical views and .a cross-section. The tool shows

Die Größe des Schneidwinkels kann man beiao two cutting lips α and b, and as are either a longer handle C on one end face or one on each end face for handling the same. Handle arranged. The size of the cutting angle can be set at

Beim Arbeiten liegt sowohl die Schneidkante wie auch der Führungswulst an der zu bearbeitenden Fläche an, und es tritt durch die gleichzeitig nach vorwärts gerichtete und drehende Schaberbewegung eine Abwälzung auf dem Führungswulst ein, wodurch die schälende Spannabnahme an der zu bearbeitenden Fläche erreicht wird.by changing the pitch and bevel angle χ or y or by changing the pitch ratio, select it appropriately. When working, both the cutting edge and the guide bead are in contact with the surface to be machined, and the simultaneous forward and rotating scraper movement causes a rolling on the guide bead, whereby the peeling clamping decrease is achieved on the surface to be machined.
