Abstract

Hydraulic saw tensioner having two saw tensioners which are arranged one above the other in the effective direction of the pistons, are hydraulically interconnected and the piston rows of which are offset perpendicularly to the saw-blade plane by half the piston separation of the individual saw tensioners, so that the entire system exhibits half the piston separation of the individual saw tensioners and thus allows an extremely thin board cut. In this arrangement, supports with interspaces are arranged between the saw tensioners, on which supports the upper saw tensioner is supported and between which the crosspieces or the wedges of the buckles can be received.

Description

Es sind hydaulische Sägenspanner für Gattermaschinen bekannt, bei denen die Wirkflächen der Hydraulikkolben in axialer Richtung versetzt angeordnet sind. Da bei diesen hydraulischen Sägenspannern die Kolben mit ihrer gegen die Angel wirkenden Fläche in einer Ebene liegen, ist eine sehr enge Kolbenteilung nicht möglich.They are hydraulic saw clamps for gate machines known in which the active surfaces of the hydraulic pistons are arranged offset in the axial direction. There with these hydraulic saw clamps with their pistons lie in one plane against the surface a very narrow piston division is not possible.

Der Erfindung liegt die Aufgabe zugrunde, einen hydraulischen Sägenspanner zu schaffen, der Sägeblätter bzw. Angeln mit extrem kleinem Abstand hydraulisch spannt. Der erfindungsgemäße hydraulische Sägenspanner besteht aus zwei Sägenspannern bekannter Bauweise, die in Wirkrichtung der Hydraulikkolben versetzt in zwei Ebenen angeordnet sind und zwischen denen sich Stützen befinden, zwischen denen die Angeln angeordnet werden können, die von dem unteren hydraulischen Sägenspanner gespannt werden, der direkt auf dem Gattermaschinenrahmen aufliegt. Der auf den Stützen angeordnete zweite obere hydraulische Sägenspanner ist senkrecht zur Wirkrichtung der Kolben um ca. eine halbe Kolbenteilung gegenüber dem unteren Sägenspanner, der direkt auf dem Maschinenrahmen aufliegt, versetzt, wobei die beiden hydraulischen Sägenspanner etwa die gleiche Kolbenteilung aufweisen. Vorzugsweise sind die beiden hydraulischen Sägenspanner hydraulisch miteinander verbunden und sind vorzugsweise jeweils beidseitig der Angeln angeordnet, so daß das gesamte Sägenspannersystem aus vier mit Kolben bestückten Sägenspannern besteht. The invention has for its object a hydraulic saw clamps to create the saw blades or fishing with extremely small distances hydraulically tense. The hydraulic saw tensioner according to the invention consists of two saw clamps of known design, the offset in two in the effective direction of the hydraulic pistons Layers are arranged and between which there are supports between which the hinges are arranged can by the lower hydraulic saw tensioner be tensioned directly on the gate machine frame lies on. The second on the supports upper hydraulic saw clamp is perpendicular to Direction of action of the pistons by about half a piston pitch opposite the lower saw clamp, which is directly on the Machine frame rests, offset, the two hydraulic saw clamps about the same piston pitch exhibit. Preferably the two are hydraulic saw clamps hydraulically with each other connected and are preferably on both sides of the Fishing arranged so that the entire saw tensioner system consists of four saw clamps equipped with pistons.  

Es sind auch Anordnungen möglich, wo in jeder Ebene nur ein Sägenspanner ist, der dann jedoch die Angeln bzw. Sägen durch eine Schwenkbewegung eines mit der Angel verbundenen Spannhebels spannt.Arrangements are also possible wherever in each level is only a saw tensioner, but then the hinges or sawing by swiveling one with the Angel connected tensioning lever tensions.

Fig. 1 zeigt einen erfindungsgemäßen hydraulischen Sägenspanner in Seitenansicht, bestehend aus den beiden unteren Sägenspannern (1.1; 1.2), auf denen sich die äußeren Sägenspanner (2.1; 2.2) durch die Stützen (3) abstützen, die durch die Stützenhalterungen (4) mittels Schraube (5) gehalten werden. Die unteren Sägenspanner (1.1; 1.2) spannen mit ihren Kolben (6) die kurzen Angeln (8.1) über die Keile (9) und die oberen Sägenspanner (2.1; 2.2) spannen mit ihren Kolben (7) die langen Angeln (8.2) über die Keile (9). Die Angeln (8.1; 8.2) spannen die Sägeblätter (11). Die unteren Sägenspanner stützen sich auf dem Gatterrahmen (10) ab. Fig. 1 shows a hydraulic saw clamp according to the invention in side view, consisting of the two lower saw clamps ( 1.1; 1.2 ), on which the outer saw clamps ( 2.1; 2.2 ) are supported by the supports ( 3 ) by means of the support brackets ( 4 ) Screw ( 5 ) are held. The lower saw clamps ( 1.1; 1.2 ) with their pistons ( 6 ) span the short hinges ( 8.1 ) over the wedges ( 9 ) and the upper saw clamps ( 2.1; 2.2 ) span over the long hinges ( 8.2 ) with their pistons ( 7 ) the wedges ( 9 ). The hinges ( 8.1; 8.2 ) tension the saw blades ( 11 ). The lower saw clamps are supported on the frame ( 10 ).

Fig. 2 zeigt den erfindungsgemäßen Sägenspanner in Wirkrichtung der Kolben mit der Kolbenteilung (T) der unteren Sägenspanner (1.1; 1.2) und der oberen Sägenspanner (2.1; 2.2), wobei die Kolben der oberen Sägenspanner (7) gegenüber den Kolben der unteren Sägenspanner (6) um ca. T/2 versetzt sind. Fig. 2 shows the saw clamp according to the invention in the effective direction of the pistons with the piston pitch ( T ) of the lower saw clamps ( 1.1; 1.2 ) and the upper saw clamps ( 2.1; 2.2 ), the pistons of the upper saw clamps ( 7 ) compared to the pistons of the lower saw clamps ( 6 ) are offset by approximately T / 2.

Fig. 3 zeigt den erfindungsgemäßen Sägenspanner in Draufsicht mit der Nutzlänge des unteren Sägenspanners NL 1 und der Nutzlänge des oberen Sägenspanners NL 2, die mindestens der Breite des Angriffslagers der Treibstange der Gattermaschine entspricht. Fig. 3 shows the saw clamp according to the invention in plan view with the useful length of the lower saw clamp NL 1 and the useful length of the upper saw clamp NL 2 , which corresponds at least to the width of the attack bearing of the drive rod of the gate machine.
