Abstract

The rotary cutter for a planing machine has two narrow interchangeable cutting blades with their edges projecting alongside undercut recesses in the disc shaped body of the head, as in the main patent. Each blade is supported by a strip secured behind it, with its inner edge resting on the sloping surface of the head of a countersunk screw. When the head is screwed inwards, this inner edge, which slopes, is lifted. The strip incorporates rounded projections which fit into grooves in the clamping pieces and in grooves in the blades.

Description

Hobelkopf mit austauschbaren WendemessernPlaner head with interchangeable reversible knives

mit einem Anschlagelement Die vorliegende Erfindung bezieht sich auf einen Hobelkopf mit austauschbaren Wendemessern gemäß Oberbegriff von Anspruch 1.with a stop element The present invention relates to a planing head with exchangeable reversible knives according to the preamble of claim 1.

Aus dem Hauptpatent P 28 11 669.0 ist es dazu bekannt, die Wendemesser aus Schnellstahl durch Pratzen gegen den Wellenkörper des Hobelkopfes zu pressen. Diese Hobelmesser aus Schnellstahl weisen eine genügende Breite auf, so daß die zulässige Flächenpressung bei den aus Leichtmetall bestehenden entsprechenden Teilen des Hobelkopfes nicht überschritten wird.From the main patent P 28 11 669.0 it is known to the reversible knife made of high-speed steel to be pressed against the shaft body of the planer head using claws. These planing knives made of high-speed steel have a sufficient width so that the permissible surface pressure for the corresponding parts made of light metal of the planer head is not exceeded.

Häufig ist nun die Verwendung von Hobelmessern aus Hartmetall erwünscht, die aus Preis-und Fertigungsgründen in möglichst kleiner Abmessung ausgeführt sein sollen. Diese Hartmetall-Wendemesser sind also streifenartig ausgeführt und so schmal, daß bei einem Einbau der eingangs beschriebenen Art die zulässige Flächenpressung der Teile des Hobelkopfes überschritten würde.The use of hard metal planing knives is often desirable, which, for price and manufacturing reasons, have the smallest possible dimensions should. These carbide reversible knives are designed like stripes and so narrow, that with an installation of the type described above, the permissible surface pressure the parts of the planer head would be exceeded.

Aufgabe der vorliegenden Erfindung ist daher die Schaffung eines Hobelkopfes mit Wendemessern aus den verschiedensten Werkstoffen und mit kleinstmöglichen Abmessungen, die auf optimale Schnittbedingungen einstellbar sind.The object of the present invention is therefore to create a planer head with reversible knives made of a wide variety of materials and with the smallest possible dimensions, which can be adjusted to optimal cutting conditions.

Diese Aufgabe wird dadurch gelöst, daß zum Halten der Wendemesser im Hobelkopf gelagerte Stützleisten vorgesehen sind.This object is achieved in that to hold the reversible knife Support strips mounted in the planing head are provided.

Damit lassen sich auch extrem schmale Wendemesser aus Hartmetall im Hobelkopf sicher festklemmen, ohne die Anlageflächen zu beschädigen. Bei Verwendung einer angepassten Stützleiste ist es auch möglich, im gleichen Hobelkopf neben Wendemessern aus Hartmetall auch Wendemesser aus Schnellstahl einzubauen.This means that extremely narrow reversible knives made of carbide can also be used in the Clamp the planer head securely without damaging the contact surfaces. Using With an adapted support bar, it is also possible to use the same planer head next to reversible knives made of carbide, reversible knives made of high-speed steel can also be installed.

Der erfindungsgemäße Hobelkopf ist somit gegenüber der bekannten Ausführung vielseitiger verwendbar.The planing head according to the invention is thus compared to the known design more versatile.

Im folgenden sind Ausführungsbeispiele der Erfindung unter Bezugnahme auf die Zeichnungen näher beschrieben.Embodiments of the invention are hereinafter referred to described in more detail on the drawings.

Es zeigen: Fig. 1 Hobelkopf von der Seite, teilweise geschnitten.They show: Fig. 1 planing head from the side, partially cut.

Fig. 2 Stützleiste von der Seite.Fig. 2 support bar from the side.

Fig. 3 Schnitt nach Linie II - II in Fig. 2.FIG. 3 section along line II - II in FIG. 2.

Am Wellenkörper 1 des Hobelkopfes 2 sind einander gegenüberliegend mit Befestigungsschrauben 3 zwei Pratzen 4 befestigt.On the shaft body 1 of the planer head 2 are opposite one another two claws 4 attached with fastening screws 3.

Zwischen den Anlageflächen 5 von Wellenkörper t und den Anlageflächen 6 von Pratzen 4 sind Stützleisten 7 gelagert, deren zylindrische Nocken 8 in Vertiefungen 9 der Pratzen 4 eingreifen.Between the contact surfaces 5 of the shaft body t and the contact surfaces 6 of claws 4 support strips 7 are mounted, the cylindrical cams 8 in recesses 9 of the claws 4 engage.

Die Stützleiste 7 ist so abgekröpft, daß sie zusammen mit der Anlagefläche 5 einen Spalt 10 bildet, in dem das Wendemesser 11 angeordnet ist. Weitere Nocken 12 der Stützleiste 7 greifen in eine Nut 13 des Wendemessersil ein und bilden so eine formschlüssige Verbindung zwischen Hobelkopf 2 und Wendemesser 11.The support bar 7 is bent so that it is together with the contact surface 5 forms a gap 10 in which the reversible knife 11 is arranged. More cams 12 of the support bar 7 engage in a groove 13 of the reversible knife rope and thus form a positive connection between planer head 2 and reversible knife 11.

Die Stützleisten 7 weisen geneigte Anschlagflächen 14 auf, die am Anschlagkegel 15 des Anschlagelements 16 anliegen. Dieses Anschlagelement 16 ist beim Ausführungsbeispiel als handelsübliche Senkschraube ausgebildet, die im Wellenkörper 1 eingeschraubt ist und durch deren Verdrehen sich das Wendemesser 11 über die Stützleiste 10 genau auf den Flugkreis einstellen läßt.The support strips 7 have inclined stop surfaces 14 which are on Stop cone 15 of stop element 16 are in contact. This stop element 16 is in the embodiment as a commercially available countersunk screw, which is in the shaft body 1 screwed in is and by twisting the reversible knife 11 can be adjusted precisely to the flight circle via the support bar 10.

Durch Festziehen der Befestigungsschrauben 3 wird das Wendemesser 11 über die Pratze 4 und die Stützleiste 7 sicher gegen die Anlagefläche 5 gepresst und im Hobelkopf 2 festgehalten.By tightening the fastening screws 3, the reversible knife 11 pressed securely against the contact surface 5 via the claw 4 and the support strip 7 and held in the planer head 2.
