Description

Messerwelle für Holzhobelmaschinen Messerwellen für Holzhobelmaschinen, deren Schneiden an einer Zylindermantelfläche liegende Schraubenlinien bilden, sind bekannt.Knife shaft for wood planing machines Knife shafts for wood planing machines, the cutting edges of which form helical lines lying on a cylinder jacket surface known.

Bei den bekannten Messerwellen dieser Art haben die Messer keine genügend feste Stütze, infolgedessen die Schneiden beim Hobeln angehoben werden und Späne zwischen Messer und Messerkopf eindringen, was eine reine Hobelarbeit verhindert.In the known knife shafts of this type, the knives do not have enough solid support, as a result of which the cutting edges are lifted during planing and chips penetrate between knife and knife head, which prevents pure planing work.

Den Gegenstand der Erfindung bildet eine Verbesserung derartiger Geräte, die darin besteht, daß die schraubenflächenförmig gebogenen Messer mittels entsprechend gewundenen Deckplatten gegen schraubenflächenförmige Seitenflächen des Messerkopfes angepreßt werden. Der Druck wirkt auf die ganze Messerfläche, wie das bei geradflächigen Messern bekannt ist. Alle Punkte der Messerschneiden werden mit gleicher Kraft gegen ihre Unterlage gedrückt, so daß ein Abheben der Messer während der Arbeit nicht eintreten kann.The subject of the invention is an improvement of such devices, which consists in the fact that the helically curved knife by means of corresponding winding cover plates against helical side surfaces of the cutter head be pressed. The pressure acts on the entire knife surface, as is the case with straight-surfaced ones Knives is known. All points of the knife edges are counteracted with the same force their base is pressed down so that the knife does not lift off during work can occur.

Die Anwendung von breiten Deckplatten ermöglicht die Benutzung von großen Schraubenmuttern zum Befestigen der Deckplatten, was zur gleichmäßigen Verteilung des die Messer festhaltenden Druckes beiträgt. Dabei ist ein genaues Einstellen der Messer immer leicht möglich, wozu die Deckplatten nur ein wenig gelockert werden müssen.The use of wide cover plates enables the use of large screw nuts for fastening the cover plates, resulting in even distribution of the pressure holding the knives. This requires precise setting the knife is always easily possible, for which the cover plates are only loosened a little have to.

Ein weiterer Vorteil des Erfindungsgegenstandes besteht in der gleichmäßigen Massenverteilung, demzufolge das Gerät in jeder Beziehung gut ausgewichtet ist. Die Zeichnung zeigt ein Ausführungsbeispiel, in Abb. i in Ansicht und in Abb. 2 in Schnitt nach der Linie II-II in Abb. i.Another advantage of the subject matter of the invention is the uniformity Mass distribution so that the device is well balanced in every respect. The drawing shows an embodiment, in Fig. I in view and in Fig. 2 in section along the line II-II in Fig. i.

Die Außenflächen des Messerkopfes d mit quadratischem Querschnitt (Abb.2) sind Schraubenflächen, desgleichen die Messerplatten b, deren Schneiden b' in je einer Schraubenlinie verlaufen (Abb. i).- Die Messerplatten liegen urter entsprechend gewundenen Deckplatten c, die mittels Schrauben d am Messerkopf befestigt sind.The outer surfaces of the cutter head d with a square cross-section (Fig.2) are screw surfaces, as are the cutter inserts b, their cutting edges b 'each run in a helical line (Fig. i) - the cutter plates are located urter correspondingly twisted cover plates c, which are fastened to the cutter head by means of screws d are.

Die Hinterkante der Deckplatten c stützt sich, wie bei geraden Messern bekannt, mit einem Ansatz g gegen den Messerkopf; infolgedessen wirkt die Kraft, die durch Anziehen der Befestigungsschrauben auf die Messerplatten wirkt, auf die ganze Messerfläche.The rear edge of the cover plates c is supported, as with straight knives known, with an approach g against the cutter head; consequently the force works which acts on the cutter inserts by tightening the fastening screws on the entire knife surface.
