Description

Maschine zum Schleifen von Rasierhoäelklingen. Gegenstand der Erfindung ist eine Maschine zum Schleifen von Rasierklingen mittels mehrerer umlaufender Schleifscheiben. Die Erfindung besteht darin, daß die Achsen der die Schleifscheiben zweckmäßig paarweise tragenden beiden nebeneinander angeordneten Wellen und die Führung für den Klingehalter, längs der die Klingen an den Scheiben hin und her geschoben werden, untereinander einen vom rechten etwas abweichenden Winkel bilden. Hierdurch wird einerseits ein Hohlschliff erzielt, anderseits durch Wandern der Berührungsbogen zwischen Schneidefläche und Schleifzylinder, parallel zur Zylinderachse, eine der gleichmäßigen Abnutzung der entsprechend bemessenen Schleifscheiben dienende Zonenverschiebung.Machine for sharpening razor blades. Subject of the invention is a machine for grinding razor blades using several rotating grinding wheels. The invention consists in that the axes of the grinding wheels expediently in pairs supporting two shafts arranged side by side and the guide for the blade holder, along which the blades are pushed back and forth on the discs, one below the other Form a slightly different angle from the right. This is on the one hand a Hollow grinding achieved, on the other hand, by wandering the contact arc between the cutting surface and grinding cylinder, parallel to the cylinder axis, one of uniform wear zone shift serving the appropriately dimensioned grinding wheels.

Auf der Zeichnung ist ein Ausführungsbeispiel der Maschine dargestellt.An exemplary embodiment of the machine is shown in the drawing.

Abb. i zeigt eine Ansicht, Abb. 2 den Grundriß der Maschine mit schräg gelagerten Schleifscheiben.Fig. I shows a view, Fig. 2 the plan of the machine with oblique mounted grinding wheels.

Abb.3 und d. zeigen schematisch hiervon abweichende Ausführungen.Fig.3 and d. show schematically different designs.

Nach der Ausführungsform gemäß Abb. i und 2 sind die Schleifscheiben 1, 2 auf der Achse 5, die Scheiben 3, q. auf der Achse 6, gegebenenfalls auf ihren Achsen einstellbar in einem solchen horizontalen Abstand voneinander gelagert, daß die zwischen den Scheibenpaaren 1, 2 und 3, q. in einem drehbaren und in der Längsrichtung verschiebbaren Klingenhalter 8 gelagerte Klinge 7 sich in den zu den Schleifebenen schrägen Arbeitsstellungen entweder mit ihren diagonal gegenüberliegenden Schneideflächen gegen die ebenso liegenden Scheiben :2 und 3 oder i und q. der Scheiben- . paare anlegen kann. Durch Regelung des Abstandes der Scheibenpaare 1, 2 und 3, 4. voneinander kann der günstigste Schneideflächenwinkel der zu schleifenden Schneiden eingestellt werden. Die Klinge 7 wird in eine beliebige Einspannvorrichtung des Klingenhalters 8 eingesetzt, der drehbar in dem im Gehäuse io auf Schwalbenschwanz geführten Schlitten 9 gelagert ist. Die Achsen der Schleifscheiben sind zur Lotrechten der Bewegungsrichtung der Klinge bzw. der Schlittenführungen, wie besonders Abb.2 zeigt, in einem spitzen Winkel angeordnet, so daß die Schneideflächen der senkrecht zum Gehäuse geführten Klinge von den Schleifscheiben in schräger Richtung bearbeitet werden. Hierdurch wird außer der erwähnten Wirkung auch erzielt, daß die Schleifscheiben gleichmäßig abgenutzt werden.According to the embodiment according to Fig. I and 2 are the grinding wheels 1, 2 on the axis 5, the discs 3, q. on axis 6, possibly on theirs Axles adjustable from each other at such a horizontal distance that between the pairs of disks 1, 2 and 3, q. in a rotatable and in the longitudinal direction displaceable blade holder 8 mounted blade 7 in the to the grinding planes inclined working positions either with their diagonally opposite cutting surfaces Against the disks lying in the same position: 2 and 3 or i and q. the disc. couples can create. By regulating the distance between the pairs of discs 1, 2 and 3, 4 the most favorable cutting surface angle of the cutting edges to be ground can be set will. The blade 7 is in any clamping device of the blade holder 8 is used, the rotatable in the slide guided in the housing io on dovetail 9 is stored. The axes of the grinding wheels are perpendicular to the direction of movement of the blade or the slide guides, as especially Fig. 2 shows, in a pointed Angle arranged so that the cutting surfaces of the run perpendicular to the housing Blade can be processed by the grinding wheels in an inclined direction. Through this In addition to the aforementioned effect, it is also achieved that the grinding wheels are uniform to be worn out.

Die Klinge wird also bei einmaligem Einspannen an allen vier Schneideflächen ihrer beiden Schneiden bearbeitet.The blade is clamped once on all four cutting surfaces machined her two cutting edges.

Wie Abb. 3 zeigt, können die Achsen 5 bzw. 6 auch geteilt sein und die einzelnen Teile i i, 12 sowohl radial wie achsial verstellbar angeordnet-werden; ebenso könnten auch gemäß Abb. d. die Achsen 13 geradegelagert sein und die Führung für die Klinge in schräger Richtung verlaufen; schließlich ist es auch möglich, statt der - Klinge umgekehrt die Schleifscheiben über die Klinge hinzubewegen.As Fig. 3 shows, the axes 5 and 6 can also be divided and the individual parts i i, 12 are arranged so that they can be adjusted both radially and axially; likewise, according to Fig. d. the axles 13 be in a straight line and the guide run in an oblique direction for the blade; after all it is also possible instead of moving the - blade the other way around, the grinding disks over the blade.
