Description

Vorrichtung zum Schärfen von Schneidwerkzeugen. Die Erfindung betrifft eine Vorrichtung zum Schärfen von Messern und besteht in der besonderen Ausbildung ihrer Schärfelemente. Diese sind alsRollen ausgebildet, die dieFortn einer Kugelzone besitzen und zum Glätten der Messerschneide dienen. Die Grundfläche der Kugelzone bildet mit der Mantelfläche eine scharfe kreisförmige Kante, die unterschnitten ist und zum Schärfen der Messerschneide dient. Die Rollen können also zum Schärfen und Glätten der Kling enschneide benutzt werden.Device for sharpening cutting tools. The invention relates to a device for sharpening knives and consists in the special training their sharpening elements. These are designed as rollers that move along a spherical zone and serve to smooth the knife edge. The base of the spherical zone forms a sharp circular edge with the outer surface, which is undercut and is used to sharpen the knife edge. So the rollers can be used for sharpening and smoothing the blade edge can be used.

In der Zeichnung ist ein Ausführungsbeispiel .des Gegenstandes der Erfindung dargestellt.In the drawing is an embodiment of the subject Invention shown.

Abb. i ist eine Vorderansicht, Abb.2 eine Seitenansicht, Abb. 3 ein Grundriß.Fig. I is a front view, Fig. 2 is a side view, and Fig. 3 is a Layout.

Abb. 4. zeigt eine der Rollen.Fig. 4. shows one of the roles.

An einem bügelförmigen Handgriff i sind in U-förmigen. Verlängerungen :2 zwei Rollen 3, 3 um Zapfen 4 drehbar und auswechselbar gelagert. Die Rollen haben den aus Abb. q. ersichtlichen Querschnitt einer Kugelzone. Sie können jedoch. auch die Form eines Kegelstumpfes oder ähnlichen Körpers besitzen. Die Grundflächen der Rollen sind zur Erzielung einer schneidenartigen Kante in bekannter Weise etwas ausgehöhlt, die Rollen können mittels einer Schraul:e 5 mehr oder weniger stark gegeneinandergepreßt werden.On a bow-shaped handle i are U-shaped. Extensions : 2 two rollers 3, 3 rotatably and interchangeably around pin 4. Have the roles the one from Fig. q. apparent cross-section of a spherical zone. However, you can. even have the shape of a truncated cone or similar body. The base of the Rollers are something to achieve a blade-like edge in a known manner hollowed out, the roles can be more or less strong by means of a screw: e 5 are pressed against each other.

Die Wirkungsweise der Vorrichtung ist folgende.-Das Messer, welches in Abb. i und 2 mit 6 bezeichnet ist, wird zwischen den aus gehärtetem Stahl oder anderem geeigneten Material bestehenden Rollen 3 hin und her geführt. Bei der Bewegung des Messers ungefähr parallel zur Drehachse der Rollen wind seine Schneide durch die scharfen Rollenkanten geschärft, bei Bewegung ungefähr senkrecht zu diesen Drehachsen geglättet. Durch Drehung der Rollen 3 können neue Stellen ihrer schneidenden Kante und ihrer glättenden Fläche zur Einwirkung auf die Klinge 6 gebracht werden. Die Regelung des Druckes der Rollen gegen das Werkstück wird mittels der Schraube 5 bewirkt. Die Foren des Handgriffs i kann beliebig gewählt werden.The mode of operation of the device is as follows.-The knife, which in Fig. i and 2 is denoted by 6, is between the hardened steel or other suitable material existing rollers 3 guided back and forth. When moving of the knife winds its cutting edge approximately parallel to the axis of rotation of the rollers the sharp roll edges sharpened, when moving approximately perpendicular to these axes of rotation smoothed. By rotating the rollers 3, new locations of their cutting edge and its smoothing surface are brought to act on the blade 6. the The pressure of the rollers against the workpiece is regulated by means of screw 5 causes. The forums of the handle i can be chosen arbitrarily.
