Description

Die Erfindung betrifft eine Gattersägenangel mit Gattersägeblatt, das durch eine Einsteck-Einschubbewegung in die Gattersägenängel einbringbar ist und an den Endkanten beidseitig befestigte Leisten trägt, die von der gezahnten Sägeblattkante ausgehend sich in Breitenrichtung des Sägeblattes erstrecken und Stützflächen haben, die sich auf Gegenflächen eines Gattersägen-Angelkastens abstützen.The invention relates to a frame saw tang with frame saw blade, which can be inserted into the frame saw nails by an insertion-insertion movement and carries strips fastened on both sides at the end edges, which extend from the toothed edge of the saw blade in the width direction of the saw blade and have support surfaces which are located on counter surfaces of a frame saw - Support the fishing box.

Eine derartige Gattersägenangel ist aus der DE-A-2844329 bekannt. Bei dieser bekannten Gattersägenangel erstrecken sich die zwischen sich das Sägeblatt haltenden Leisten im wesentlichen über die gesamte Sägeblattbreite und tragen an ihren dem Sägeblatt abgewandten Kanten Ansätze, die in einen Angelkasten hineinragen. Die Ansätze haben Stützflächen, die sich auf Gegenflächen im Angelkasten abstützen. Diese Konstruktion ist wegen der die Verbindung zwischen Leisten und Angelkasten schaffenden Ansätze aufwendig. Zudem sieht die bekannte Konstruktion keine Verstellung der Leisten in Breitenrichtung des Sägeblattes vor. Die die Leisten gegen das Sägeblatt klemmenden Schrauben und Zapfen liegen nach außen hin offen und müssen gegen ein Herausfallen gesichert werden.Such a frame saw fishing is known from DE-A-2844329. In this known frame saw tang, the strips between the saw blade extend essentially over the entire width of the saw blade and carry on their edges facing away from the saw blade approaches which protrude into a fishing box. The approaches have support surfaces that are supported on counter surfaces in the fishing box. This construction is complex because of the connection between the last and the fishing box. In addition, the known construction does not provide for adjustment of the strips in the width direction of the saw blade. The screws and pins that clamp the bars against the saw blade are exposed to the outside and must be secured against falling out.

Auch bei der Gattersägenangel nach der DE-A-21 18450 erstrecken sich die außerhalb des Angelkastens befindlichen Leisten im wesentlichen über die gesamte Breite des Sägeblattes, das eine Reihe von Löchern aufweist, um die Leisten in Richtung zur Sägeblatt-Rückkante umsetzen zu können. Von ihrem mittleren Bereich stehen von den Leisten Ansätze mit Stützflächen ab, die ein Tragprofil an einer Angel von außen umgreifen. Auch diese Konstruktion ist vergleichsweise aufwendig. Die das Sägeblatt tra-. genden Leisten sind nach außen hin nicht abgeschirmt.Also in the frame saw fishing according to DE-A-21 18450, the strips located outside the fishing box extend essentially over the entire width of the saw blade, which has a number of holes, in order to be able to move the strips towards the rear edge of the saw blade. From their central area there are lugs with support surfaces that grip a support profile on a hinge from the outside. This construction is also comparatively complex. Which carries the saw blade. bars are not shielded from the outside.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Gattersägenangel mit herstellungstechnisch und in der Handhabung vereinfachter Konstruktion zu schaffen, bei der trotz Umsetzbarkeit der Leisten die die Verbindung zwischen Sägeblatt und Angelkasten schaffenden Einrichtungen nach außen im wesentlichen abgeschirmt sind.In contrast, the invention has for its object to provide a generic gang saw with manufacturing technology and handling simplified construction in which, despite the feasibility of the strips, the devices creating the connection between saw blade and fishing box are essentially shielded from the outside.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Leisten im Inneren des Angelkastens aufgenommen sind, daß die Leisten in an sich bekannter Weise in einer sich über die gesamte Sägeblattbreite erstreckenden Reihe von Löchern in Querrichtung zur Sägeblatt-Rückkante umsetzbar sind und daß die Leisten mit einer etwa der Restbreite eines maximal heruntergeschärften Gattersägeblattes entsprechenden Längen mit ihren der Sägeblatt-Rückkante zugekehrten Stirnflächen in Anlage mit einem im Angelkasten vorgesehenen Anschlag bringbar sind, dessen Abstand von der Vorderkante des Angelkastens etwas der Länge einer Leiste entspricht.This object is achieved in that the strips are received in the interior of the fishing box, that the strips can be implemented in a manner known per se in a row of holes extending across the entire width of the saw blade in the transverse direction to the rear edge of the saw blade and that the strips with a about the remaining width of a maximally sharpened frame saw blade corresponding lengths with their end faces facing the saw blade rear edge can be brought into contact with a stop provided in the fishing box, the distance from the front edge of the fishing box corresponding somewhat to the length of a bar.

Erfindungsgemäß haben die Leisten somit nur eine Länge, die im wesentlichen der Restbreite eines maximal heruntergeschärften Gattersägeblattes entspricht und sind mit ihren Stützflächen im wesentlichen im Gattersägen-Angelkasten mit den darin vorgesehenen Gegenflächen aufgenommen. Die Leisten lassen sich in der auf der ganzen Breite des Gattersägenblattes vorgesehenen Lochreihe in Richtung der Sägeblatt-Rückkante verstellen. Die exakte jeweilige Einschubbegrenzung ergilbt sich dadurch, daß die Leisten mit ihren der Sägeblatt-Rückkante zugekehrten Stirnflächen gegen einen Anschlag im Angelkasten treten, dessen Abstand von der Angelkastenvorderkante etwa der Länge der Leisten entspricht. Dies gewährleistet, daß die Leisten stets im Inneren des Da die Länge der Leisten nicht gezielt auf die Breite des Gattersägeblattes abgestimmt werden muß, können grundsätzlich Sägeblätter mit erheblicher Länge vorgesehen werden, was eine entsprechende Verlängerung der Nutzungszeit bedingt. Die verkürzten Leisten haben einen vergleichsweise einfachen Aufbau, was nicht nur die Lagerhaltung, sondern auch die Fertigung begünstigt. Da die Leisten vollständig im Angelkasten aufgenommen sind, läßt sich die axiale Lage der die Verbindung zwischen Sägeblatt und Leisten bewerkstelligenden Zapfen in einfacher Weise durch die Innenwände des Angelkastens fixieren.According to the invention, the strips therefore only have a length which essentially corresponds to the remaining width of a maximally sharpened frame saw blade and are accommodated with their supporting surfaces essentially in the frame saw fishing box with the mating surfaces provided therein. The strips can be adjusted in the direction of the rear edge of the saw blade in the row of holes provided over the entire width of the frame saw blade. The exact respective slide-in limitation results from the fact that the strips with their end faces facing the saw blade rear edge step against a stop in the fishing box, the distance from the front edge of the fishing box corresponds approximately to the length of the strips. This ensures that the strips are always inside the. Since the length of the strips does not have to be specifically matched to the width of the frame saw blade, saw blades with a substantial length can in principle be provided, which requires a corresponding extension of the useful life. The shortened strips have a comparatively simple structure, which not only favors warehousing but also manufacturing. Since the strips are completely accommodated in the fishing box, the axial position of the pins which produce the connection between the saw blade and the strips can be fixed in a simple manner through the inner walls of the fishing box.

Um das überbreite Sägeblatt trotz schmalem bzw. normalem Angelkasten vibrationsfrei zu halten, kann der Angelkasten an seinem der Sägeblattmitte zugekehrten Bereich verbreitert sind. Dabei kann die Verbreiterungsstufe etwa auf Höhe der Gegenflächen des Angelkastens liegen und den Anschlag tragen. Eine vorteilhafte Weiterbildung der Erfindung zeichnet sich ferner dadurch aus, dass die Leisten stufenförmig abgesetzt sind derart, daß ein vorstehender Leistenabschnitt in den Durchtrittsspalt für das Sägeblatt des Angelkastens ragt. Unter Berücksichtigung der Stützflächen an den Leisten, die von den Gegenflächen des Angelkastens hintergriffen werden, ergibt sich hierdurch eine Andruckkomponente bezüglich der Leisten. Daher reicht es gemäß einer anderen Weiterbildung der Erfindung aus, wenn ein mittlerer Schraubzapfen die durch ein oder mehrere benachbarte Zentrierzapfen lagefixierte Leisten gegen das Sägeblatt verspannt.In order to keep the extra-wide saw blade free of vibration despite the narrow or normal fishing box, the fishing box can be widened at the area facing the center of the saw blade. The widening level can lie approximately at the level of the counter surfaces of the fishing box and can support the stop. An advantageous development of the invention is further characterized in that the strips are stepped in such a way that a projecting strip section protrudes into the passage gap for the saw blade of the fishing box. Taking into account the support surfaces on the strips, which are engaged by the counter surfaces of the fishing box, this results in a pressure component with respect to the strips. Therefore, according to another development of the invention, it is sufficient if a central screw pin braces the strips fixed in position by one or more adjacent centering pins against the saw blade.

Weitere Vorteile des Gegenstandes der Erfindung sind nachstehend anhand eines zeichnerisch veranschaulichten Ausführungsbeispieles näher erläutert. Es zeigt :

  • Figur 1 Gattersägenangeln und Gattersägenblatt in Seitenansicht,
  • Figur 2 den Schnitt gemäß Linie 11-11 in Fig. 1 und
  • Figur 3 den Schnitt gemäß Linie III-III in Fig. 1.
Further advantages of the subject matter of the invention are explained in more detail below with the aid of an exemplary embodiment illustrated in the drawings. It shows :
  • FIG. 1 frame saw fishing and frame saw blade in side view,
  • Figure 2 shows the section along line 11-11 in Fig. 1 and
  • 3 shows the section along line III-III in FIG. 1st

Die an den Enden 1' eines Gattersägenblattes 1 angreifenden Gattersägen-Angelkästen 2 setzen sich in je einen Schaft 3 fort, der mit nicht näher dargestellten Spannmitteln zur Festlegung des Gattersägenblattes 1 im Gatterrahmen dient.The frame saw fishing boxes 2 engaging at the ends 1 'of a frame saw blade 1 are each continued in a shaft 3 which is not closer to The clamping means shown serves to fix the frame saw blade 1 in the frame.

Im Bereich der Sägenblattenden 1' sind beiderseits höhengleich liegende, quer zur Blattlänge ausgerichtete Leisten 4 befestigt. Hierzu weist das Gattersägenblatt im Bereich der Endkanten eine parallel zu diesen verlaufende Lochreihe bestehend aus in gleichem, engem Abstand zueinander liegenden Löchern 5 auf.In the area of the saw blade ends 1 ', strips 4 which are at the same height and are oriented transversely to the blade length are fastened. For this purpose, the gang saw blade has a row of holes running parallel to these in the region of the end edges and consisting of holes 5 which are at the same, narrow distance from one another.

Die in ihrer Länge etwa der Restbreite eines maximal heruntergeschärften Gattersägenblattes 1 entsprechenden Leisten 4 lassen sich entsprechend schrittweise in Richtung der Sägeblatt-Rückenkante 1' versetzen. Solche relativ kurzen Leisten haben den Vorteil einer geringen Einschubtiefe, was die Zuordnung des Gattersägenblattes bzw. seine Entnahme aus dem Register erleichtert. Andererseits wandert die von ihnen gebildete Stützfläche 4', welche von der korrespondierenden Gegenfläche 2' des Gattersägen-Angelkastens übergriffen wird, mit.The strips 4, which correspond approximately in length to the remaining width of a maximally sharpened frame saw blade 1, can accordingly be gradually displaced in the direction of the saw blade back edge 1 '. Such relatively short strips have the advantage of a small insertion depth, which facilitates the assignment of the frame saw blade or its removal from the register. On the other hand, the support surface 4 'formed by them, which is overlapped by the corresponding counter surface 2' of the frame saw fishing box, also moves with it.

Die Leisten 4 gehen von der gezahnten Kante 1"' des Sägeblattes aus. Das Längenverhältnis von Leiste zu Gattersägenblatt-Breite beträgt etwa 1 : 2.The strips 4 start from the toothed edge 1 ″ of the saw blade. The length ratio of the strip to the frame saw blade width is approximately 1: 2.

Um die Einstecktiefe gleichmäßig zu begrenzen, weist jeder Gattersägen-Angelkasten 2 am Ende des Sägendurchtrittsspaltes 6 desselben einen Anschlag 7 auf. Gegen diesen tritt die in Einschubrichtung x liegende Stirnfläche 8 einer der paarig angeordneten Leisten 4.In order to uniformly limit the insertion depth, each gang saw fishing box 2 has a stop 7 at the end of the saw passage gap 6 thereof. The end face 8 of one of the strips 4 arranged in pairs occurs in the insertion direction x.

Der Abstand des Anschlages 7 von der Vorderkante 9 des Gattersägen-Angelkastens 2 entspricht etwa der Länge der Leisten 4.The distance of the stop 7 from the front edge 9 of the frame saw fishing box 2 corresponds approximately to the length of the strips 4.

Wie Fig. 1 entnehmbar, weist der Gattersägen-Angelkasten 2 in seinem der Sägeblattmitte zugekehrten, unteren Bereich (oberes Sägeblattende 1') eine größere Breite auf als in seinem dem Schaft 3 zugekehrten Bereich. Die Verbreiterungszone erstreckt sich in Richtung der Sägeblatt-Rückkante 1" und ist mit 10 bezeichnet. Letztere bildet flügelartige Vorsprünge. Die Verbreiterungsstufe St fällt mit der Höhe der Gegenfläche 2' zusammen. Von ihrer parallel zur Endkante verlaufenden Oberseite geht ein den Anschlag 7 bildender horizontal ausgerichteter Zapfen oder Splint aus.As can be seen in FIG. 1, the gang saw fishing box 2 has a greater width in its lower area facing the center of the saw blade (upper saw blade end 1 ') than in its area facing the shaft 3. The widening zone extends in the direction of the saw blade rear edge 1 "and is designated by 10. The latter forms wing-like projections. The widening step St coincides with the height of the counter surface 2 '. A horizontal surface forming the stop 7 extends from its top side, which runs parallel to the end edge aligned pin or cotter pin.

Wie aus den Fig. 2 und 3 ersichtlich, sind die Stützflächen 4' der Leisten 4 und die Gegenflächen 2' der Angelkästen 2 gegenläufig hinterschnitten, so daß eine Abspreiztendenz der den Angelkasten bildenden Taschenwände wirksam - unterbunden ist. Es tritt vielmehr eine die Taschenwände unter Belastung zusammenziehende Kraftkomponente auf. Diese ist zugleich auch im Sinne einer Unterstützung der Befestigung der Leisten 4 genutzt, wozu die Leisten 4 derart stufenförmig abgesetzt sind, daß ein flügelartig vorstehender, an den Sägeblattbreitseiten aufliegender Leistenabschnitt 11 verbleibt, der in eine formentsprechende Ausnehmung 12 des Sägendurchtrittsspaltes 6 ragt. Der Leistenabschnitt 11 wird in Richtung der Sägeblatt-Breitfläche druckbelastet und so festgeklemmt. Im Grunde genügt für die Befestigung der Leisten 4 daher ein etwa mittig liegender Schraubzapfen 13, der, eine Durchtrittsöffnung 14 der einen Leiste 4 sowie eines der Löcher 5 durchsetzend, in ein Innengewinde 15 der gegenüberliegenden Leiste 4 eingreift. Der Kopf des Schraubbolzens 13 ist als Senkkopf gestaltet mit Innenmehrkant.As can be seen from FIGS. 2 and 3, the support surfaces 4 'of the strips 4 and the counter surfaces 2' of the fishing boxes 2 are undercut in opposite directions, so that a spreading tendency of the pocket walls forming the fishing box is effectively prevented. Rather, a force component occurs which pulls the pocket walls together under load. This is also used in the sense of supporting the attachment of the strips 4, for which the strips 4 are stepped in such a way that a wing-like protruding strip section 11 resting on the broad sides of the saw blade remains, which protrudes into a corresponding recess 12 in the saw passage gap 6. The strip section 11 is pressure-loaded in the direction of the broad saw blade surface and is thus clamped. Basically, an approximately central screw pin 13 is sufficient for the attachment of the strips 4, which, penetrating a passage opening 14 of the one strip 4 and one of the holes 5, engages in an internal thread 15 of the opposite strip 4. The head of the screw bolt 13 is designed as a countersunk head with an internal polygon.

Der Schraubzapfen 13 ist desweiteren von je zwei Zentrierzapfen 16 flankiert, welche, ebenfalls die Löcher 5 der Lochreihe durchgreifend, die Leisten 4 mit festlegen. Der Angelkasten selbst sichert mit seinen Tascheninnenwänden die Axiallage der Zentrierzapfen 16, welche auch Randkerben aufweisen können.The screw pin 13 is further flanked by two centering pins 16 which, also penetrating the holes 5 of the row of holes, also define the strips 4. The fishing box itself secures the axial position of the centering pin 16 with its pocket inner walls, which can also have edge notches.
