Description

Die Erfindung betrifft ein Messer für Holz- und Buschhackmaschinen, dessen flacher Messerkörper mit vorragender Schneide in einer Wechselhalterung einer Messertrommel einspannbar ist.The invention relates to a knife for wood and wood chippers, its flat knife body with protruding cutting edge in an interchangeable holder a knife drum can be clamped.

Bei einer bekannten Hackmaschine besteht die Wechselhalterung aus zwei Druckplatten für die beiden Flachseiten des jeweiligen Messers, wobei die eine Druckplatte zwischen zwei den übrigen Trommelkörper bildenden Außenscheiben angeordnet und die zweite Druckplatte über eine oder mehrere, auch eine entsprechende Öffnung des Messerkörpers durchsetzende Schrauben festspannbar ist. Ferner sind in Längsrichtung des Messers wirkende Stellschrauben an der feststehenden Druckplatte oder einem mit dieser verbundenen Teil vorgesehen, um ein Nachstellen bzw. Einstellen des Messers zu ermöglichen. Zum Nachschleifen oder bei Messerbruch müssen alle diese Verbindungen gelöst, das Messer entfernt und dann das nachgeschliffene bzw. neue Messer unter Herstellung dieser Verbindungen wieder eingesetzt werden. Diese Arbeit ist langwierig und wird durch Abnützungen bzw. Korrosion der Schrauben beim rauhen Betrieb noch erschwert. Der Messerkörper selbst stellt zwar einen relativ einfachen Bauteil dar, muß aber trotzdem genau bearbeitet werden und überdies zur Gänze aus einem Material hergestellt sein, das eine ausreichend lange Lebensdauer der Schneide und damit des Gesamtmessers gewährleistet. In a known chopping machine, the interchangeable holder consists of two pressure plates for the two flat sides of the respective knife, the a pressure plate between two outer disks forming the remaining drum body arranged and the second pressure plate over one or more, too screws penetrating a corresponding opening in the knife body can be tightened. There are also adjusting screws acting in the longitudinal direction of the knife on the fixed pressure plate or one connected to it Part provided to allow readjustment or adjustment of the knife. All these connections must be used for regrinding or in the event of a knife break loosened, the knife removed and then the reground or new knife can be used again to produce these compounds. This work is lengthy and is caused by wear or corrosion of the screws rough operation even more difficult. The knife body itself represents a relative is a simple component, but must still be processed precisely and moreover be made entirely of a material that has a sufficiently long lifespan the cutting edge and thus the overall knife.

Diese Schwierigkeiten bzw. Nachteile werden bei einem Messer der eingangs genannten Art erfindungsgemäß dadurch beseitigt, daß der Messerkörper aus zwei Teilen, nämlich einer auswechselbaren, die Schneide aufweisenden Klinge und einem diese Klinge abstützenden Trägerkörper besteht, welch letzterer mit einer Ausnehmung zum Einlegen der ihn zum vollständigen Messerkörper ergänzenden Klinge versehen ist, deren Dicke nur einen Bruchteil der Dicke des Trägerkörpers beträgt.These difficulties or disadvantages are the case with a knife initially mentioned type eliminated according to the invention in that the knife body of two parts, namely an interchangeable one with the cutting edge Blade and a support body supporting this blade, which the latter with a recess for inserting it into the complete knife body complementary blade is provided, the thickness of which is only a fraction of the Thickness of the carrier body is.

Die Klinge kann ein ganz einfach geformter Stanzteil aus einem eine entsprechende Festigkeit bzw. Härtungsmöglichkeit aufweisenden Material sein, wogegen der Trägerkörper nur die notwendige Stützfestigkeit, nicht aber die für die Schneide notwendige Härte oder Härtbarkeit aufweisen muß. Dieser Stützteil nimmt bei entsprechender Auslegung der Gesamtkonstruktion auch die für die Wechselhalterung und Einstellung notwendigen Schrauben bzw. Schraubendurchführungen und Schraubenabstützungen auf. Zu diesem Zweck wird vorgesehen, daß die Klinge und die sie aufnehmende Ausnehmung des Trägerkörpers nur über einen Teil der Länge dieses Trägerkörpers reichen.The blade can be a very simply shaped stamped part from one appropriate strength or hardening material, whereas the carrier body only the necessary support strength, but not for the cutting edge must have the necessary hardness or hardenability. This support part with appropriate design of the overall construction also takes the for Interchangeable bracket and adjustment of necessary screws or screw bushings and screw supports. For this purpose it is provided that the blade and the recess of the carrier body receiving it only extend over part of the length of this support body.

Bei den meisten Ausführungen wird die Breite der Klinge der flachseitigen Breite des Trägerkörpers im Aufnahmebereich entsprechen, doch sind auch Sonderformen mit Überstand der Klinge oder des Trägerkörpers über den jeweiligen anderen Teil möglich.In most designs, the width of the blade is the flat side Correspond to the width of the carrier body in the receiving area, but are also Special shapes with the blade or support body protruding above the respective one other part possible.

Eine besonders einfache Konstruktion ergibt sich, wenn die Klinge, bezogen auf die Umlaufrichtung der Messertrommel, an der Vorderseite des Trägerkörpers angeordnet und mittels der Wechselhalterung an diesen andrückbar ist. Dabei ergibt sich der zusätzliche Vorteil, daß zu einem allfälligen Auswechseln der Klinge nur die Einspannung des Messers gelockert werden muß, der Trägerkörper aber im übrigen in der Wechselhalterung verbleiben kann.A particularly simple construction results if the blade, based on the direction of rotation of the knife drum, at the front of the Carrier body arranged and can be pressed onto this by means of the interchangeable holder is. This has the additional advantage that it can be replaced the blade only has to loosen the clamping of the knife, the carrier body can remain in the interchangeable holder.

Um zu verhindern, daß sich die Klinge gegenüber dem Trägerkörper nach der Seite hin verstellt, sollen entsprechende Maßnahmen getroffen werden. Nach einer der vorgesehenen Möglichkeiten weist die Klinge an der von der vorstehenden Schneide abgewandten Seite einen oder mehrere Vorsprünge auf, die zur Seitenführung der Klinge gegenüber dem Trägerkörper in entsprechend geformte Teile der Aussparung dieses Trägerkörpers eingreifen.To prevent the blade from facing the support body Adjusted to the side, appropriate measures should be taken. According to one of the options provided, the blade points to that of the one or more projections on the side facing away from the cutting edge, corresponding to the lateral guidance of the blade relative to the carrier body engage shaped parts of the recess of this carrier body.

Nach einer anderen Möglichkeit ist die Klinge mit dem Trägerkörper über in zugeordnete Löcher bzw. Vertiefungen des jeweils anderen Teiles eingreifende Stifte, Passfedern od. dgl. zusätzlich verbunden.According to another possibility, the blade with the carrier body is over engaging in assigned holes or depressions of the other part Pins, feather keys or the like additionally connected.

Es ist in manchen Fällen auch sinnvoll, bei der Messernachstellung nicht den gesamten Messerkörper, sondern nur die Klinge allein nachzustellen. Um dies zu ermöglichen, ist bei der einen oben beschriebenen Ausführungsform die Klinge an über den Trägerkörper vorragenden Stiften mit ihre Nachstellung zulassenden Langlöchern geführt.In some cases it also makes sense not to adjust the knife the entire knife body, but only the blade alone. Around to enable this is the one described above Blade on pins protruding over the carrier body with their adjustment permitting Elongated holes.

Bisher wurde davon ausgegangen, daß Klingen mit einseitiger Schneide Verwendung finden. Es ist aber auch ohne weiteres möglich, die Klinge als Wendeklinge mit an zwei parallelen Seiten vorgesehenen Schneiden auszubilden. Dabei muß darauf geachtet werden, daß die eben nicht benützte Schneide geschützt bleibt. Man wird sie also in der Ausnehmung des Trägerkörpers freistellen und zur Seitenabstützung der Klinge die oben erwähnten Stifte, Passfedern oder ähnliche Halterungen vorsehen. Im Extremfall ist sogar eine Ausführung denkbar, nach der eine zunächst quadratische Klinge an allen vier Seiten mit Schneiden versehen ist. Für Sonderfälle können auch Klingen mit gezähnten Schneiden eingesetzt werden.So far it was assumed that blades with one-sided cutting edge Find use. But it is also possible to use the blade as a reversible blade with cutting edges provided on two parallel sides. Care must be taken to protect the cutting edge that has not been used remains. It will therefore be cut out in the recess of the carrier body and for the lateral support of the blade the above-mentioned pins, keys or provide similar brackets. In extreme cases, an execution is even conceivable according to the one initially square blade with cutting on all four sides is provided. For special cases, blades with serrated edges can also be used be used.
