Description
Einrichtung zur Führung eines hin- und herschwingenden Werkzeuges zum Formhobeln. Die Erfindung bezweckt, eine Einrich tung zu schaffen, die zur Führung eines hin- und herschwingenden Werkzeuges zum Formhobeln dient, mittels welchem bestimmte Formen eines Werkstückes, zum Beispiel die Schaufeln eines Turbinenrades, aus dem Vol len herausgearbeitet werden sollen.
Ein solches Werkzeug arbeitet mittels zweier Schneidkanten, von denen die eine die eigent liche Form aus dem Werkstoff herausschnei- idet, während die andere, zur ersteren mei stens rechtwinklige Schneidkante zu der dem Vorschub des Werkzeuges entsprechenden Spanabnahme dient. Der Einfachheit halber ist im nachstehenden die erstgenannte gante als Formschneidkante, die, andere als Vor schubschneidkante bezeichnet.
Die Erfindung bezieht sich darauf, .den eine hin- und hergehende Bewegung ausfüh renden Werkzeugstahl so zu führen, dass er beim Arbeitsgang eine dem herzustellenden Profile entsprechende Bahn beschreibt und dass seine beiden Schneidkanten in jedem Punkte die schnittgerechte Stellung ein nehmen.
Erfindungsgemäss wird bei einer Einrich tung zur Führung eines hin- und herschwin genden Werkzeuges zum Formhobeln, das schwenkbar in einem Schwinghebel gelagert ist, der in einer dem herzustellenden Profil entsprechenden Führung bewegt wird, das Werkzeug mittels einer zweiten Führung während des Vorschubes derart geschwenkt, ,dass seine Schneidkante bei der Spanabnahme stets die Richtung der Normalen auf die her zustellende Profillinie inne hat.
Auf der Zeichnung ist als Ausführungs- beispiel eine Einrichtung zum Formho beln von Turbinenschaufeln dargestellt, und zwar in Fig. 1 in schematischer Darstellung, während

Device for guiding a back and forth swinging tool for planing. The aim of the invention is to provide a device that serves to guide a reciprocating tool for form planing, by means of which certain shapes of a workpiece, for example the blades of a turbine wheel, are to be worked out from the vol len.
Such a tool works by means of two cutting edges, one of which cuts the actual shape out of the material, while the other cutting edge, which is mostly at right angles to the former, is used to remove the chips corresponding to the advance of the tool. For the sake of simplicity, in the following the first-mentioned gante is referred to as a form cutting edge, the other referred to as a push cutting edge.
The invention relates to .den a reciprocating movement executing tool steel so that it describes a path corresponding to the profile to be produced during the operation and that its two cutting edges take the right cut position at every point.
According to the invention in a device for guiding a reciprocating tool for planing, which is pivotably mounted in a rocker arm, which is moved in a guide corresponding to the profile to be produced, the tool is pivoted by means of a second guide during the advance, that its cutting edge always has the direction of the normal to the profile line to be produced when removing chips.
In the drawing, a device for Formho belts of turbine blades is shown as an exemplary embodiment, namely in Fig. 1 in a schematic representation, while

framing causes both cutting edges to be in the correct position.
