MesserKnife
Die Erfindung bezieht eic;» auf ein Messer mit einem Trägerkörper und einem an ihn befestigten Sehneidkörper.The invention relates to a knife with a carrier body and a cutting body attached to it.
Es ist bekannt, Messer mit einem solchen Trägerkörper und eines Sehneidkörper zu versehen, wobei letzterer aus Stellit oder Hartmetall besteht. Beide Sehneidwerkstoffe haben den Nachteil, daß sie nur mit Diamant- oder Borasonschleifscheiben geschliffen werden können, woraus relativ hohe Endbearbeitungekosten resultieren.It is known to provide knives with such a carrier body and a cutting edge body, the latter being made of stellite or hard metal. Both cutting edge materials have the disadvantage that they can only be ground with diamond or borason grinding wheels, which results in relatively high finishing costs.
Der Torliegenden Erfindung liegt die Aufgabe zugrunde, ein Messer mit einem Schneidkörper zu schaffen, dessen Endbearbeitungekosten maßgeblich herabgesetzt werden können wobei die SteMzeit des Messers insbesondere bei der HoIs- oder Holzwerkstoffbearbeitung nicht beeinträchtigt werden darf.The object of the invention is to create a knife with a cutting body whose finishing costs can be significantly reduced, whereby the cutting time of the knife must not be impaired, particularly when processing wood or wood-based materials.
Zur Lösung der Aufgabe wird erflndungegemäß vorgeschlagen, daß der Sohneidkörper au« einem aoefaleelerten Sehnellarbeiteetehl auf pttlveraetallurgleeher Basis besteht. Hierdurch erreicht man den Vorteil, daß das Messer bei weitem nicht mehr eo bruohgefährdet 1st, da das Sintermaterlal eine geringere Sprödlgkelt aufweist. Zudem läßt sieh dieses Material mit normalen Korundsohelben schleifen·To solve the problem, it is proposed according to the invention that the sintered body consists of a finely ground sintered metal on a platinum-based basis. This has the advantage that the knife is far less prone to breakage, since the sintered material is less brittle. In addition, this material can be ground with normal corundum sandpaper.
Weitere Ausgestaltungen der Erfindung ergeben eich aue der nachfolgenden Beschreibung eines AusfUhrungsbeiepieles anhand der Zeichnungefigur·Further embodiments of the invention can be seen from the following description of an embodiment based on the drawing figure.

Zeiehmtflg «eigt «In Maohinenmeeaer im Querschnitt. Ein TrMgefktfrp«? 1 bfteteht aus util«giert#tB Werkzeugstahl, sum Beispiel 0 45« Der Tfögejpleöfper weist im Quereehnitt etwa Parallelogrammform auf. Eine Ltfageeeite 2 des Parallelogramme bildet eine Stirnfläche, eine eich hieran in einem spitzen Winkel 3 anschließende Fläche k eine Freifläche. In die Stirnfläche ist eine Ausnehmung 3 eingearbeitet, die bis zur Freifläche k reicht, Die Ausnehmung trägt einen Schneidkörper 6 aus einem Sintermetallkörper, der auf pulrermetallurgischer Basis hergestellt ist. Er ist mittels Silberlot am Trägerkörper hart angelötet und bildet eine Sohneidkante 7.Drawing shows a cross-section of a masonry cutter. A sintered metal cutter 1 is made of used tool steel, for example 0.45mm. The cutter has a roughly parallelogram shape in cross-section. A parallel side 2 of the parallelogram forms a front surface, and a surface k adjoining it at an acute angle 3 forms a clearance surface. A recess 3 is machined into the front surface and extends to the clearance surface k . The recess carries a cutting body 6 made of a sintered metal body which is manufactured using powder metallurgy. It is hard-soldered to the carrier body using silver solder and forms a parallel edge 7.
Ee ist möglieh, den Schneidkörper 6 und gegebenenfalls auch den Trägerkörper 1 in der Längseretreckung des Messers - diese liegt senkrecht zur Zeichenebene - bu profilieren oder auch gerade zu lassen. En hat sieh herausgestellt, daß das erfindungsgemäß ausgebildete Messer sich herrorragend zum Bearbeiten von Holz, Harthole und Spanplatten eignet.It is possible to profile the cutting body 6 and, if necessary, also the carrier body 1 in the longitudinal extension of the knife - this is perpendicular to the plane of the drawing - or to leave it straight. It has been found that the knife designed according to the invention is ideal for processing wood, hardwood and chipboard.
