Description

Messerkopf für Hobelmaschinen Messerköpfe mit mehreren Schneiden sind bekannt, dessen Messer aber alle für Außenschliff eingerichtet sind, wodurch bei jedem Nachschleifen der Gesamtdurchmesser des Messers kleiner und die Messer selbst leicht exzentrisch würden, was die Genauigkeit der Einstellung beeinträchtigte. Andererseits sind auch zylindrische Messer mit der Schneide am Mantel bekannt, die entweder aus einem zylindrisch gebogenen Stahlmantel bestehen oder aus einer Scheibe mit einer schrägen Sägezahnlücke ähnlichem Ausschnitt. Bekannt ist es auch, daß durch Klappen jedes einzelne Messer festgehalten wird.Cutter head for planing machines Cutter heads with several cutting edges are known, but the knives are all set up for external sharpening, which results in Each time you regrind the overall diameter of the knife and the knife itself would become slightly eccentric, affecting the accuracy of the setting. On the other hand, cylindrical knives with the cutting edge on the jacket are also known which consist either of a cylindrically curved steel jacket or of a disc with a cutout similar to an oblique sawtooth gap. It is also known that is held by folding each individual knife.

Die Erfindung besteht nun darin, zylindrische Messer der letztgenannten Art mit mehreren Schneiden herzustellen, die den Vorzug haben, beim Schleifen, das immer von innen erfolgt, ihren Durchmesser stets beizubehalten.The invention now consists in cylindrical knives of the latter Type of manufacture with several cutting edges that have the advantage of grinding that always done from within, always maintaining their diameter.

Der Erfindungsgegenstand ist in Fig. I dargestellt mit vier Wellenmessern 2,. 5, 6, 7 mit einer bis vier Schneidkanten. Das untere-Messer 2 der vier Messer ist bekannt. Die Messer 2, 5, 6, 7, welche durch zwei Klappen 3 mittels Schrauben ¢ oder durch die beiden Klappen gehende Bolzen mit Muttern oder durch Keil oder Exzenter 8 in den Längsbohrungen 9 der Welle festgehalten werden. Ein Herausfliegen der Messer wird durch diese Anordnung verhindert. Ist :eine Messerkante stumpf, so wird die Befestigungsvorrichtung 3 oder 8 gelöst, das Wellenmesser wird bis zur nächsten Messerkante zur obersten Angriffshöhe gedreht und darauf ohne weiteres Messen befestigt, so daß hierdurch viel Zeit erspart und größte Genauigkeit sowie Höchstleistungen erzielt werden.The subject of the invention is shown in Fig. I with four wave knives 2 ,. 5, 6, 7 with one to four cutting edges. The lower knife 2 of the four knives is known. The knives 2, 5, 6, 7, which by means of two flaps 3 by means of screws ¢ or bolts going through the two flaps with nuts or wedges or Eccentric 8 are held in the longitudinal bores 9 of the shaft. A flying out the knife is prevented by this arrangement. Is: a knife edge blunt, so the fastening device 3 or 8 is released, the wave knife is up to next knife edge turned to the uppermost attack height and then without further ado Measure attached so that this saves a lot of time and great accuracy as well Maximum performance can be achieved.

Fig.II zeigt eine Messerwelle mit dem Wellenmesser 7, welches z. B. durch die Platte 3 sowie Schrauben q. befestigt ist.Fig.II shows a knife shaft with the wave knife 7, which z. B. through the plate 3 and screws q. is attached.

Fig. III stellt ein Wellenmesser 5 im Schnitt mit. vier Schneidkanten dar. Um stets ein genaues Hobeln zu erzielen, darf das Messer nur innen nachgeschliffen werden.Fig. III shows a wave knife 5 in section. four cutting edges In order to always achieve precise planing, the knife may only be sharpened on the inside will.

Fig. IV zeigt einen seitlichen Exzenter oder Keilbefestigung i o, i i, welche in der Aussparung i q. des Messerkopfes versenkt ist, wodurch mittels Bolzen 13 und Mutter 12 die keilartigen Spannfutter i o, i i sich fest um die Messer in den Bohrungen beim Anziehen klemmen.Fig. IV shows a lateral eccentric or wedge attachment io, ii, which in the recess i q. of the cutter head is sunk, as a result of which the wedge-like chucks io, ii are firmly clamped around the knives in the bores when tightened by means of bolts 13 and nuts.
