Description
Die Erfindung betrifft eine Vorrichtung zum Schleifen von Messerklingen, die mit ihrem Rücken auf einer Stütze ,aufliegen und zwischen Schleifkörpern hin und her bewegt werden. Im Gegensatz zu bekannten Schleifvorrichtungen, bei denen die Schneidenflächen der gegen ein festes Widerlager abgestützten Klingen zwischen schräg gestellten Schleifflächen bewegt werden, benutzt die Schleifvorrichtung gemäß der Erfindung parallel gestellte Schleifflächen, die in einem Gestell drehbar gelagert sind, und eine höhenverstellbare Stütze, in deren Nut der Rücken des zu schleifenden Messers geführt wird. An den parallel stehenden Schleifflächen läßt sich die Anlage der Schneidenflächen unmittelbar genau beobachten und somit ein Schleifen der Messer gerade dort vornehmen, wo es erforderlich ist. Die drehbare Lagerung der Schleifkörper und die Höhenverstellbarkeit der Messerstütze gestattet eine vollständige Ausnutzung der Schleifflächen.The invention relates to a device for sharpening knife blades with their Back on a support, rest and be moved back and forth between grinding tools. In contrast to known grinding devices, in which the cutting surfaces of the blades supported against a fixed abutment between inclined grinding surfaces are moved, uses the grinding device according to the invention placed in parallel Sanding surfaces that are rotatably mounted in a frame, and one height-adjustable Support in whose groove the back of the knife to be sharpened is guided. To the parallel grinding surfaces, the contact of the cutting surfaces can be directly and precisely watch and sharpen the knife exactly where it is necessary is. The rotatable mounting of the grinding wheel and the height adjustability of the Knife support allows full utilization of the grinding surfaces.
In der Zeichnung ist die Vorrichtung zum Schleifen von Messerklingen nach der Erfn> dung an einem Ausführungsbeispiel veranschaulicht. Es zeigen:The drawing shows the device for grinding knife blades according to the invention Application illustrated using an exemplary embodiment. Show it:
Abb. ι das Schleifwerkzeug in Aufsicht,Fig. Ι the grinding tool in plan,
Abb. 2 eine Seitenansicht zu Abb. 1.Fig. 2 is a side view of Fig. 1.
An den parallel stehenden Schenkeln 1,2 eines U-förmigen Rahmens sind die beiden Schleifkörper 3, 4 drehbar gelagert. Innerhalb der Schenkel des U-förmigen Rahmens ist die Stütze 6 mit der Nut 7 zur Führung des Messerrückens höhenverstellbar, beispielsweise durch eine in den Rahmen eingesetzte Spindel 8 mit Stellrad 9.On the parallel legs 1,2 of a U-shaped frame are the two Grinding body 3, 4 rotatably mounted. Inside the legs of the U-shaped frame is the Support 6 with the groove 7 for guiding the knife back height adjustable, for example by a spindle 8 with adjusting wheel 9 inserted into the frame.
Um ein Messer mit der gekennzeichneten Schleifvorrichtung zu schleifen, wird dieses mit dem Klingenrücken in die Nut 7 der Stütze 8 eingesetzt, dann wird die Stütze in ihrer Höhenlage so eingestellt, daß sich die Schneide des Messers zwischen den beiden Schleifkörpern 3 und 4 befindet. Beim Schleifen wird die Messerldinge in der Nut 7 unter abwechselndem Andrücken der Schneide an die Schleifkörper 3 'und 4 hin und her bewegt. Dabei kann genau beobachtet werden, wo die Schneide geschliffen werden soll. Die gleichzeitige Abnutzung der Schleifkörper ist einmal durch deren drehbare Lagerung gewährleistet und dann auch durch die Höhenverstellbarkeit der Klingenstütze 6.In order to sharpen a knife with the marked sharpening device, this inserted with the back of the blade into the groove 7 of the support 8, then the support is in their height is adjusted so that the cutting edge of the knife is between the two Abrasive tools 3 and 4 is located. When grinding, the knife things are in the groove 7 under alternately pressing the cutting edge on the grinding body 3 'and 4 moves back and forth. It can be observed exactly where the cutting edge is to be ground. The simultaneous Wear of the grinding wheels is guaranteed once by their rotatable mounting and then also through the height adjustability of the blade support 6.
