Description

Eine besondere Art von Kreismessern wird entweder mit sogenannter Facenschneide (ebener Schliff) oder aber mit Balligschneide, die jener gegenüber besondere Vorzüge hat, versehen. Sowohl Facen- als Balligschneide werden vorzüglich, am Knieschleifstein rein handwerksmäßig geschliffen. Es sind aber auch sogenannte Facenschleifmaschinen bekannt, auf welchen die Facenschneide in billiger und zweckmäßiger Weise, die Balligschneide jedoch: nur behelfsmäßig und unvollkommen geschliffen Werden kann. Im letzteren Falle werden verschiedene Facenschliffe so aneinandergereiht, daß die einzelnen Facen Taögenten der gewünschten Balligkurve bilden. Eine Facenschleifmaschine, mit welcher ein solcher Schliff ausgeführt werden kann, ist in Abb. 1 dargestellt.A special type of circular knife is either made with a so-called facet cutter (flat Bevel) or with a convex cutting edge, which has special advantages over this one. Both bevel and crowned cutting edges are excellent, on the knee whetstone they are purely handcrafted sanded. But there are also so-called face grinding machines known, on which the face cutting edge in a cheap and convenient way, the crowning edge however: Can only be sanded provisionally and imperfectly. In the latter case different facets are lined up in such a way that the individual facets are perfect the desired crowned curve. A face grinding machine with which a Such a cut can be made is shown in Fig. 1.

Abb. 2, 3 und 4 stellen nun die Stellungen bei dem Balligschleifen eines Messers dar, die zeitlich nacheinander eingestellt werden müssen. Die Facenwinkel sind mit i, k, I bezeichnet. Je weniger die Facenwinkel voneinander abweichen und je mehr aufeinanderfolgende Einstellungen vorgenommen werden, um so mehr nähert sich der Schliff der gewünschten Balligkurve, um so teurer und umständlicher wird aber auch das Schleifverfahren'.Fig. 2, 3 and 4 now show the positions for the convex grinding of a knife, which must be set one after the other. The bevel angles are denoted by i, k, I. The less the bevel angles differ from one another and the more successive adjustments are made, the closer the cut approaches the desired crowned curve, but the more expensive and laborious the grinding process becomes.

Zum Balligschleifen von Langmessern sind nun bereits Maschinen* bekanntgeworden, bei denen das Messer während des Schleifens um eine Achse hin und her geschwenkt wird, die im Mittelpunkt der Balligkurve liegt. Diese Maschinen sind aber nur zum Balligschleifen von Langmessern verwendbar.Machines * have already become known for spherical grinding of long knives, at which the knife is swiveled back and forth about an axis during grinding, which lies in the center of the crowned curve. These machines are only for crown grinding can be used by long knives.

Die den Gegenstand der Erfindung bildende Schleifmaschine hat nun eine Einrich- ' tung, durch die das Werkstück während des Schleifens von dem Antrieb aus um eine zu der Schleifscheibe parallele senkrechte Achse hin und her geschwenkt wird, wobei jedoch die sonst bei Maschinen zum Schleifen von Kreismessern durch, die Umlaufachse des Werkzeugträgers gehende senkrechte Schwenkachse seitlich von der Umlaufachse, also in den jeweiligen Mittelpunkt der Balligkurve des Kreismessers, verlegt und daher zumThe grinding machine forming the subject of the invention now has a Einrich- ' device, through which the workpiece during grinding from the drive to one the grinding wheel parallel vertical axis is pivoted back and forth, however which otherwise in machines for grinding circular knives through the axis of rotation of the Tool carrier going vertical swivel axis to the side of the axis of rotation, i.e. in the respective center point of the crowned curve of the circular knife, relocated and therefore to the

Auf der Zeichnung ist der Erfindungsgegenstand in Abb. 5 im Grundriß und Abb. 6 im Seitenriß dargestellt.In the drawing, the subject of the invention is shown in Fig. 5 in plan and Fig. 6 shown in side elevation.

Der Erfindungsgegenstand weicht gegenüber der einfachen Facenschleifmaschine zunächst dadurch ab, daß der Drehpunkt des Werkstückträgers außerhalb der Spannfutterwelle/κ, und zwar in den Mittelpunkt der gewünschten Balligkurve n, etwa bei 0, angebracht ist. Ferner ist 'ein mechanischer Antrieb für ein Kurbeltriebw*rk O1 vorgesehen, welches vermittels einer Triebstange ρ aen Werkstückträger und damit auch das Rundmesser während des Schleifens so um den Drehpunkt hin und her schwingt, daß die Schmirgelflächie in jedem Augenblick die Balligkurve berührt. Hierbei ist die Trieb-The subject of the invention differs from the simple facet grinding machine in that the pivot point of the workpiece carrier is located outside the chuck shaft / κ, specifically in the center of the desired crowned curve n, approximately at 0 . Furthermore, a mechanical drive for a crank mechanism O 1 is provided, which by means of a drive rod ρ aen workpiece carrier and thus also the circular knife swings back and forth around the pivot point during grinding so that the emery surface touches the crowned curve at any moment. Here is the instinct

Abb. 7 stellt die Endstellung des Messers q mit der BaUigkurve κ zum Schmirgelstein r dar. Das Messer- dreht sich während des Schleifens vom Anfangspunkts der Kurve« um den Drehpunkt 0 in Richtung des Pfeils bis zum Endpunkt t der Kurve und wieder zurück, usf., bis völlige. Schärfe erreicht ist. Der Drehpunkt ο kann durch Verschieben des Werkstückträgers längs der Nut« zu der Aufspannwelle wie auch durch axiales Verschieben der Auf spannwelle trC zum Schleifstein/-, was durch Versetzen der Bunde m1 erreicht wird, sowohl an den" Durchmesser des zu schleifenden Kreismessers als auch an den Radius der Balligkurve des Messers angepaßt werden. Auch kann die Länge der Balligkurve, durch Verändern des Hubes bzw. Verstellen des Angriffspunktes der Triebstange/» verändert werden. Verschiedene Angriffspunkte der Schubstange sind durch die Löcher ν auf der Kurbelscheibe w angegeben.Fig. 7 shows the end position of the knife q with the building curve κ to the emery stone r . The knife rotates during grinding from the starting point of the curve around the pivot point 0 in the direction of the arrow to the end point t of the curve and back again, and so on . until complete. Sharpness is achieved. The pivot point ο can be adjusted by moving the workpiece carrier along the groove «to the clamping shaft as well as by axially moving the clamping shaft trC to the grindstone / -, which is achieved by moving the collars m 1 , both to the" diameter of the circular knife to be ground as well as The length of the crowned curve can also be adjusted by changing the stroke or adjusting the point of application of the drive rod / ». Different points of application of the push rod are indicated by the holes ν on the crank disk w .
