Description

Schärfvorrichtung mit in verschiedenen Winkeln einstellbarer Feile, insonderheit zum Schärfen der Messer von landwirtschaftlichen Maschinen. Die Erfindung betrifft eine Vorrichtung zum Schärfen von Messern, insbesondere der Messer von landwirtschaftlichen Maschinen, und :besteht in der besonderen Einrichtung des Werkzeuges zum Einstellen verschiedener S chärfwinkel.Sharpening device with file that can be adjusted at different angles, especially for sharpening the knives of agricultural machines. The invention relates to a device for sharpening knives, in particular the knives of agricultural machines, and: consists in the special arrangement of the tool for setting different sharpening angles.

Eine Ausführungsform des. Werkzeuges ist auf der Zeichnung in Abb. i in Ansicht, Abb, a im Längsschnitt und Alb-. 3 in einer Ansicht von oberdargestellt. , Die Vorrichtung besteht aus einem mit seitlichen Handriffen cl, & versehenen Gehäuse a, das zur Aufnahme der Schärffeile b und ihrer Befestigungsmittel .dient.An embodiment of the tool is on the drawing in Fig. I in view, Fig, a in longitudinal section and Alb-. 3 shown in a view from above. The device consists of a housing a which is provided with side handles cl, & and which serves to hold the sharpening file b and its fastening means.

Die Feile b wird in dem Gehäuse a durch ein Widerlager c festgeklemmt, das durch zwei an seinen Enden angreifende Querkeile d' und d2 in seiner Schräglage verändert werden kann. Das Widerlager c -preßt die Feile gegen die das andere Widerlager bildende Gehäusewand e. Diese bildet nach dem einen Ende zu (an :der Einführungsstelle f ) die Gegenführung für das zu schärfende ,Messer und ist in ihrem weiteren Verlauf so gewölbt, @daß die Feile b in den verschiedenen Schräglagen, entsprechend derjenigen des einstellbaren Widerlagers c, an ihr Anlage findet.The file b is clamped in the housing a by an abutment c, that by two transverse wedges d 'and d2 engaging at its ends in its inclined position can be changed. The abutment c -presses the file against the other abutment forming housing wall e. This forms at one end to (to: the introduction point f) the counter guide for the knife to be sharpened and is in its further course arched so that the file b is in the various inclined positions, corresponding to that of the adjustable abutment c, is attached to it.

D,ie Handhabung des Werkzeuges ist folgende: Sollen z. B. die Messer einer Häckselmaschine geschärft werden, so wird die Vorrichtung an Ort und Stelle zunächst mit dem Einführungsschlitz f auf die Messerschneide gesetzt, so daß die Führungsfläche e an dem Messerrücken anliegt; dann werden .die Querkeile dl und d2 so weit gelöst, daß sich das Widerlager c und damit die Feile b,dem Messerschneidewinkel anpassen können. In dieser Stellung wird die Feile durch entsprechenden Anzug .der Querkeile d' und d2 und die dadurch erfolgende Einstellung des Widerlagers c festgehalten.The handling of the tool is as follows: Should z. B. the knives a chopper are sharpened, the device is in place first set with the insertion slot f on the knife edge, so that the Guide surface e rests on the back of the knife; then .die cross wedges dl and d2 so far that the abutment c and thus the file b, the knife cutting angle can customize. In this position, the file is tightened accordingly Cross wedges d 'and d2 and the resulting adjustment of the abutment c held.

Die Messerschneide wird dann in der üblichen Weise durch Hin- und Herführen des Werkzeuges auf dem Werkstück geschärft.The knife edge is then in the usual way by going back and forth Bring the tool sharpened on the workpiece.

Durch Anziehen des einen und entsprechendes Nachlassen des anderen Querkeiles kann also der Schärfwinkel den jeweils zu bearbeitenden Messerschneiden .angepaßt werden.By tightening one and releasing the other accordingly The sharpening angle of the knife edge to be machined can therefore be used as a cross wedge .be adjusted.

Die Oberkeile können auch durch andere Elemente, z. B. Schrauben a. dgl., ersetzt werden.The top wedges can also be replaced by other elements, e.g. B. Screws a. Like. To be replaced.
