Description
Die Erfindung betrifft eine Schleifmaschine zum Schleifender Breitseiten von Sägeblättern und ähnlichen flachen Werkstücken.The invention relates to a grinding machine for grinding the broad sides of saw blades and similar flat workpieces.
Bei bekannten Maschinen dieser Art werden die Sägeblätter zwischen zwei Sandsteinen hindurchgeführt, die mit verschiedenen Umfangägeschwindigkeiten umlaufen. Der größere Stein mit höherer Umfangsgeschwindigkeit verrichtet die Schleifarbeit, der kleinere Stein mit kleinerer Umfangsgeschwindigkeit drückt das Werkstück an den größeren Stein an und regelt seinen Vorschub beim Schleifen.In known machines of this type, the saw blades are between two sandstones passed through, with different circumferential speeds circulate. The larger stone with a higher peripheral speed does the grinding work, the smaller stone with the lower peripheral speed presses the workpiece the larger stone and regulates its feed when grinding.
Bei dieser Art des Anpressens und des Transportes des Werkstückes muß der die Schleifarbeit verrichtende große Schleifstein ein Sandstein sein, ein Kunststein ist nicht verwendbar, da bei der nur linienförmigen Andrückfläche des zylindrischen Andrücksteines ein Kunststein unruhig arbeitet und eine ungleichmäßige, wellige Schleiffläche hinterläßt.With this type of pressing and transporting the workpiece the large grindstone doing the grinding work must be a sandstone, a Artificial stone cannot be used because the linear pressure surface of the cylindrical pressure stone an artificial stone works unsteadily and an uneven, leaves a wavy sanding surface.
Das Arbeiten an einem Sandstein bringt für den Schleifer die bekannte Gesundheitsgefährdung mit sich, die bei einem Kunststein weniger groß ist. Es geht deshalb das Bestreben dähin, nach Möglichkeit für Schleifarbeiten, wie das Schleifen der Seitenflächen von Sägens usw., Kunststeine zu verwenden.Working on a sandstone brings the familiar to the grinder Health hazard with it, which is less great with an artificial stone. It's going ok hence the endeavor, if possible, for grinding work, such as grinding the side surfaces of saws, etc., to use artificial stones.
Dieses ist durch die neue Andrückvorrichtung möglich gemacht.This is made possible by the new pressure device.
Nach der Erfindung erfolgt die Anpressung des Werkstückes an den Schleifstein durch eine einstellbare Druckfläche und der Transport der Sägeblätter usw. durch je ein vor und hinter dem flächenförmigen Druckstück angeordnetes, zwangläufig angetriebenes Druckrollenpaar. Die Andrückfläche ist dem Umfang des Kunststeines angepaßt und bewirkt ein sanftes und gleichmäßiges Andrücken der Säge an den Kunststein.According to the invention, the workpiece is pressed against the grindstone through an adjustable pressure surface and the transport of the saw blades etc. one in front of and one behind the sheet-like pressure piece arranged and positively driven Pair of pressure rollers. The pressure surface is adapted to the circumference of the artificial stone and causes the saw to press gently and evenly against the artificial stone.
In beispielsweiser Ausführung ist die neue Andrückvorrichtung in oder Zeichnung in den Abb. I und 2 dargestellt.In an exemplary embodiment, the new pressing device is in or Drawing shown in Figs. I and 2.
Zum Andrücken der zu schleifenden Säge oder eines ähnlichen, blattförmigen Werkstückes an den Kunststein I dient das Druckstück 2, dessen Druckfläche zweckmäßig der Krümmung des Außenumfanges des Kunststeines I angepaßt ist. Das Druckstück 2 sitzt an einem auf den Säulen 3 gleitenden Schlitten 4, der durch die Schraubenspindel 5 zu verstellen ist. Auf der Schraubenspindel 5 dreht sich die mit Handgriffen versehene Schraubenmutter 6, welche drehbar, aber axial unverschiebbar in der auf den Enden der Säulen 3 befestigten Traverse 7 gelagert ist. Durch Drehung der Mutter 6 kann somit das Druckstück 2 gegenüber dem Kunststein I in die durch das zu schleifende Werkstück bedingte Lage eingestellt werden.For pressing down on the saw to be ground or a similar, leaf-shaped saw Workpiece on the artificial stone I, the pressure piece 2, whose pressure surface is expedient the curvature of the outer circumference of the artificial stone I is adapted. The pressure piece 2 sits on a slide 4 that slides on the columns 3 and passes through the screw spindle 5 is to be adjusted. The one provided with handles rotates on the screw spindle 5 Screw nut 6, which is rotatable but axially immovable in the on the ends the pillars 3 attached traverse 7 is mounted. By turning the nut 6 can thus the pressure piece 2 opposite the artificial stone I in the by the to be ground Workpiece-related position can be set.
Die Hindurchführung des Werkstückes 8 (Abb. 2) wird durch die vor ,und hinter dem Druckstück angeordneten, zwangläufig angetriebenen Transportrollenpaare 9 bewirkt. Der durch die beiden Transportrollenpaare bewirkte Zwangsvorschub des Werkstäckes kann auch in anderer Weise geschehen. Das Druckstück erstreckt sich über die ganze Breite des Kunststeines I, seine Stärke und damit die Größe seiner Andrückfläche richtet sich nach der Beschaffenheit des Kunststeines und des zu bearbeitenden Werkstückes. Die wirksame Andrückfläche des Kunststeines muß so groß sein, daß der Kunststein zu einem ruhigen, gleichmäßigen Arbeiten gezwungen wird.The passage of the workpiece 8 (Fig. 2) is through the front , and positively driven pairs of transport rollers arranged behind the pressure piece 9 causes. The forced feed of the caused by the two pairs of transport rollers Work pieces can also be done in other ways. The pressure piece extends across the entire width of artificial stone I, its strength and thus the size of its The contact surface depends on the nature of the artificial stone and the one to be processed Workpiece. The effective pressure surface of the artificial stone must be so large that the Artificial stone is forced to work calmly and evenly.
