Description

Den Gegenstand der Erfindung bildet eine neue zweckmäßige Hilfsschleifvorrichtimg an Bandsägen, womit die durch Löten uneben gewordenen Rückenfläche des ßandsägeblattes wieder ebengeschliffen werden kann, um so die Dauerhaftigkeit der Säge zu erhöhen. Der Antrieb der Vorrichtung erfolgt unmittelbar durch das zu bearbeitende in Lauf gesetzte Sägeblatt selbst.The subject of the invention is a new useful auxiliary grinding device Band saws, with which the back surface of the sanding saw blade that has become uneven due to soldering can be ground again to increase the durability of the saw. Of the The device is driven directly by the one to be processed Saw blade itself.

ίο In den Zeichnungen ist die neue Einrichtung in zwei Abb. ι und 2 im Aufriß dargestellt. ίο In the drawings is the new facility in two Fig. ι and 2 shown in elevation.

Die Vorrichtung besteht aus einen Fuß k, auf welchem ein durch eine Schraubenspindel Z verstellbares Lager g aufgesetzt ist für die mittels Stellringes i gehaltene, drehbare Achse />. Auf dieser wiederum ist eine Schmirgelscheibe e sowie eine im Durchmesser erheblich kleinere Friktionsscheibe d zwischen zwei Beilagsscheiben / f mittels Schraubenmutter h befestigt und die Friktionsscheibe zweckmäßig in einer Aussparung der .Schleifscheibe etwas versenkt. In dem Winkelraum, den die beiden Scheiben c und d bilden, ist die Arbeitsstellung des Werkstückes bzw. Sägeblattes b, und zwar gelangt die Schleifscheibe mit deren Rücken und die Friktionsscheibe mit deren einer Seitenfläche dabei in Anlage. Durch seitliches Andrücken der Friktionsscheibe d an das in Lauf befindliche Bandsägeblatt b wird somit die Schmirgelscheibe e auch in Drehung versetzt und durch die Schraubenspindel I nach Bedarf an den Sägerücken herangeführt und dieser dabei geschliffen. The device consists of a foot k on which a bearing g, adjustable by a screw spindle Z, is placed for the rotatable axis held by means of the adjusting ring i. On this, in turn, an emery disk e and a friction disk d, which is considerably smaller in diameter, are fastened between two washers / f by means of a screw nut h and the friction disk is expediently sunk somewhat in a recess in the grinding disk. The working position of the workpiece or saw blade b is in the angular space formed by the two disks c and d , namely the grinding wheel comes into contact with its back and the friction disk with one of its side faces. By laterally pressing the friction disk d against the running band saw blade b , the emery disk e is also set in rotation and brought up to the saw back as required by the screw spindle I and this is ground in the process.
