Walkvorrichtung an Maschinen zum Schleifen von gewölbten Flächen an Messer-oder sonstigen Klingen.
Die vorliegende Erfindung bezieht sich auf eine Walkvorrichtung an Maschinen zum Schleifen gewölbter Messer- oder sonstiger Klingenflächen, bei der das Hin-und Herschwingen (leg längs der Schleiffläche vorbeiziehbaren Klingenhalters mittels einer mechanisch auf-und abbewegten Gleitschiene erfolgt. die auf einem Hebelarm des drehbaren Klingenhalters wirkt.
Von den bekannten Vorrichtungen dieser Art unterscheidet sich die vorliegende dadurch, dass die Schiene der Walkvorrichtung so angeordnet ist. dass der Klingen halter beim Yorbeiziehen längs der Schleiffläche allmählich oder gegebenenfalls auch stufenweise in Schwingungen von verschiedenem Winkel versetzt wird, zum Zwecke, die Klinge von der Angel nach der Spitze

Die Gleitschiene c, auf der der an einem Ende des Klingenhalters a aufgesetzte Arm aufruht, ist an einem Halter ri befestigt, der, wie bekannt. auf einem durch Kurbelgetriebe oder dgl. auf- und niederbewegbaren Schlitten e sitzt. In diesem Halter ist die Schiene c um eine Schraube f schwingbar und in der gewünschten Stellung feststellbar befestigt, so daB sie zu der Vorschubrichtung des Klingenhalters eine schräge Richtung einnehmen kann.
Da dann die Auflagestelle des Armes b auf der Schiene c und damit der wirksame Hebelarm des Hebels b sich ändert. während der senkrechte Hub der Schiene c konstant bleibt, ändert sich also der Drehwinkel des Klingenhalters beim Auf- und Niederbewegen des Schlittens e und bei der hin und her gehenden Bewegung des Klingenhalters a. womit eineAnderung der Rundung der KHngenfächen ver- bunden ist.

Milling device on machines for grinding curved surfaces on knives or other blades.
The present invention relates to a flexing device on machines for grinding curved knife or other blade surfaces, in which the swinging back and forth (lay the blade holder that can be pulled past along the grinding surface by means of a mechanically up and down slide rail) takes place on a lever arm of the rotatable blade holder works.
The present one differs from the known devices of this type in that the rail of the flexing device is arranged in this way. that the blade holder is gradually or, if necessary, gradually set in vibrations from different angles when pulling along the grinding surface, for the purpose of moving the blade from the tang to the point
EMI1.1
working grinding machines.
The slide rail c, on which the arm placed at one end of the blade holder a rests, is attached to a holder ri which, as is known. sits on a slide e which can be moved up and down by means of a crank mechanism or the like. In this holder, the rail c is pivotable about a screw f and can be fixed in the desired position so that it can assume an oblique direction to the advancing direction of the blade holder.
Since then the support point of the arm b on the rail c and thus the effective lever arm of the lever b changes. while the vertical stroke of the rail c remains constant, the angle of rotation of the blade holder changes when the slide e is moved up and down and when the blade holder a moves back and forth. which is associated with a change in the rounding of the neck surfaces.
Becomes. as the drawing illustrates, a slide rail c with a straight path is selected.
EMI1.2
To change the lye of the lever arm sliding on it (b).
