Description

Die Erfindung bezieht sich auf die bekannte Sägeangel mit Exzenterspanuvorrichtung und federndem Spannkeil nach Patent 87I I97, bei der die Längenänderung des Gattersägeblattes durch Zusammendrücken oder durch Ausdehnen des geschlitzten Spannkeils ausgeglichen wird. Es hat sich als vorteilhaft erwiesen, den federnden Spannkeil auch für den Längenausgleich hydraulisch gespannter Gattersägeblätter zu verwenden. Doch ist der Federweg des Spannkeils allein in den Fällen unzureichend, in denen verhältnismäßig große Kräfte übertragen werden müssen. Auch besteht der Nachteil, daß der mit der Gattersägeangel nicht fest verbundene Keil verlorengeht und er dann durch einen schlitzlosen und daher federlosen Keil ersetzt wird.The invention relates to the known saw rod with eccentric clamping device and resilient clamping wedge according to patent 87I I97, in which the change in length of the gang saw blade compensated for by compressing or expanding the slotted clamping wedge will. It has proven to be advantageous to use the resilient clamping wedge for the Use length compensation of hydraulically tensioned gang saw blades. It still is the spring deflection of the clamping wedge alone is insufficient in those cases in which it is proportionate great forces have to be transferred. There is also the disadvantage that the one with the Frame saw tang not firmly connected wedge is lost and then through a slotless and therefore springless wedge is replaced.

Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß mehrere der mit den Gattersägeangeln verbundenen Spannteile mit einem oder mehreren quer zu jedem Spannteil angeordneten länglichen Schlitzen versehen sind.According to the invention, these disadvantages are avoided in that several of the clamping parts connected to the frame saw rods with one or more oblong slots arranged transversely to each clamping part are provided.

Eine weitere Ausbildung dieser Schlitze an einem Exzenterhebel zur Erhöhung des Federweges besteht darin, daß sie nach dem Griff- bzw. Schlagende zu verlängert sind.Another formation of these slots on an eccentric lever for Increasing the spring travel consists in that it closes after the grip or end of the stroke are extended.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Sie veranschaulicht ein in den Gattersägerahmen eingespanntes Gattersägeblatt.It illustrates a frame saw blade clamped in the frame saw frame.

Das Gattensägeblatt a hängt an der Angel b, deren Spannexzenterhebel c auf der Unterlage d ruht, die ihrerseits unter Zwischenschaltung eines Spannkeiles e auf dem oberen Gattersägebalken f ruht. Die untere Gattersägeangel g trägt das Widerlager h, das gegen den Untergattersägebalken I abgestützt ist. Das untere Widerlager h, der Spannkeil e, die Spannexzenterunterläge d und der Exzenterhebel haben je einen quer zur Zugrichtung des Gattersägeblattes angeordneten länglichen Schlitz k.The gang saw blade a hangs on the tang b, whose clamping eccentric lever c rests on the base d, which in turn with the interposition of a clamping wedge e rests on the upper frame saw beam f. The lower frame saw tang g carries this Abutment h, which is supported against the lower frame saw beam I. The lower abutment h, the clamping wedge e, the clamping eccentric supports d and the eccentric lever each have an elongated slot arranged transversely to the pulling direction of the gang saw blade k.

Der Schlitz k des Exzenterhebels ist dabei bis in das Griff- oder Schlagende verlängert.The slot k of the eccentric lever is up in the handle or Long stroke end.

Bei Bedarf kann auch das untere Druckstück der Angel g mit einem Schlitz k und die Spannexzenterunterlage d mit mehreren parallel zueinander angeordneten Schlitzen versehen sein.If necessary, the lower pressure piece of the tang g can also have a slot k and the clamping eccentric pad d with several arranged parallel to one another Be provided with slots.

Beim Spannen des Gattersägeblattes a bewirkt diese Spanneinrichtung, daß sämtliche Teile, die mit einem oder mehreren Längsschlitzen k versehen sind, zusammengedrückt werden. Die Längenänderung wirkt sich dabei anteilig auf die einzelnen Teile der Spanneinrichtung aus. Alle Teile der Spanneinrichtung nehmen demnach an der Längenänderung teil.When tensioning the gang saw blade a, this tensioning device causes that all parts that are provided with one or more longitudinal slots k, be squeezed. The change in length has a proportional effect on the individual Parts of the clamping device. All parts of the clamping device therefore accept the change in length.

Besonders der in das Griff- bzw. Schlagende hinaus verlängerte Schlitz k des Spannexzenterhebels bewirkt eine weitgehende Zusammendrückbarkeit des Spannexzenters in der Zugrichtung des Gattersägeblattes.Especially the slot that is extended into the handle or striking end k of the clamping eccentric lever causes the clamping eccentric to be largely compressible in the pulling direction of the gang saw blade.
