Maschine zum Schärfen von Sägen.Machine for sharpening saws.

Patentiert im Deutschen Reiche vom 19. April 1925 ab.Patented in the German Empire on April 19, 1925.

Von den bekannten Maschinen zum Schärfen von Sägen mittels eines in der Sägeblattebene schwingenden, von einem Schubkurbelgetriebe gesteuerten Schleifscheibenträgers unterscheidet sich der Erfindungsgegenstand dadurch, daß der durch den Antriebsmotor ausbalancierte Schleifscheibenträger und das eine Ende der Schubstange des Schubkurbelgetriebes auf besonderen Drehzapfen eines Halters sitzen, der lösbar mit einem Bandsägengestell verbunden ist. .Dadurch ist eine einfache, motorisch angetriebene, leicht an einem Gestell anbringbare Schärfmaschine geschaffen worden.Of the known machines for sharpening saws by means of one in the saw blade plane vibrating grinding wheel carrier controlled by a slider crank mechanism the subject matter of the invention in that the balanced by the drive motor Grinding wheel carrier and one end of the push rod of the crank mechanism sit on special pivot of a holder, which can be detached with a band saw frame connected is. .This makes a simple, motor-driven, easily attached to a frame attachable sharpening machine has been created.

In der Zeichnung ist die neue Sägenschärfmaschine in der Seitenansicht dargestellt. Der Elektromotor α, welcher mit der Schleifspindel δ starr gekuppelt ist, gibt derselben die zum Schliff erforderliche Umdrehung. Die Schleifspindel b, welche gleich-In the drawing, the new saw sharpening machine is shown in side view. The electric motor α, which is rigidly coupled to the grinding spindle δ, gives the same the rotation required for grinding. The grinding spindle b, which is the same

zeitig eine Schnecke c trägt, steht mit dem Schneckenradi/ im Eingriff. Die Schneckenradwelle e besitzt an ihren beiden Enden exzentrisch je einen Zapfen/, auf welche die sich gegenüberliegenden Schubstangeng1 mit einem Ende gesteckt sind, während die anderen Enden drehbar mit dem Zapfen h des Halters t verbunden sind. Dadurch nun, daß ' der Schleifscheib&nträger im Drehpunkt k desearly carries a worm c , is in engagement with the worm radius /. The worm gear shaft e has at its two ends eccentrically a pin / on which the opposite push rods 1 are inserted with one end, while the other ends are rotatably connected to the pin h of the holder t . As a result, that 'the grinding wheel & n carrier in the pivot point k of the

ίο Halters t aufgehängt ist, schwingt derselbe, von dem Schubkurbelgetriebe gesteuert, bei der Drehung des Antrielbsmotors α in der Sägeblattebene. Der Schleifscheibenträger ist durch den Antriebsmotor α ausbalanciert.ίο Holder t is suspended, it swings, controlled by the crank mechanism, when the drive motor α rotates in the plane of the saw blade. The grinding wheel carrier is balanced by the drive motor α.

Die Vorschubbewegung des Sägeblattes geschieht in der Weise, daß die am Schleifscheibenträger j befindliche Schraube m beim Abwärtsschwingen der Maschine auf den Hebel« drückt, welcher um den Punkte» drehbar ist und an seinem einen Ende einen drehbaren Teil ρ trägt. Wird nun der Hebel« durch die Schraube m niedergedrückt, so drückt Teil ρ gegen den vorspringenden Teil des Bolzens/·, welcher durch Eingriff in die Zähne des Sägeblattes das Vorschieben der Zähne bewirkt. Die Feder s gibt dem Bolzen q einen beschleunigten Rücklauf, um die geschärften Zähne zu schonen.The feed movement of the saw blade takes place in such a way that the screw m located on the grinding wheel carrier j presses on the lever "which is rotatable about the point" and carries a rotatable part ρ at one end when the machine swings downwards. If the lever is now depressed by the screw m , part ρ presses against the protruding part of the bolt / · which, by engaging the teeth of the saw blade, causes the teeth to advance. The spring s gives the bolt q an accelerated return in order to protect the sharpened teeth.

Die jeweilige Einstellung des Vorschubes geschieht durch die Schraub em, die Verstelibiarkeit der ganzen Maschine dagegen läßt sich" leicht durch Verschiebung des Halters^ vornehmen, welcher lösbar mit dem Bandsägengestell bzw. einem anderen Gestell verbunden ist.The respective setting of the feed is done by the screw em, the adjustability the whole machine, on the other hand, can "easily be removed by moving the holder ^ make which is detachably connected to the band saw frame or another frame.
