Description

Technisches GebietTechnical area

Die Erfindung bezieht sich auf eine Gattersäge mit einem über Führungen entlang seitlicher Führungsschienen geführten Sägegatter, das einen Gatterrahmen mit zwei Streckbalken zum Einspannen paralleler, nur in einer Hubrichtung schneidender Sägeblätter aufweist, und mit einem Schubkurbeltrieb, der über seitliche Schubstangen im Bereich des ihm näheren Streckbalkens mit dem Sägegatterverbunden ist. Eine solche Gattersäge ist der DE 27 21 842 zu entnehmen.The invention relates to a gang saw with a guide rails guided along lateral guide rails, which has a gate frame with two extension bars for clamping parallel, only in a stroke cutting blades, and with a sliding crank drive, the lateral push rods in the vicinity of the draw bar is connected to the saw gate. Such a gang saw is the DE 27 21 842 refer to.

Stand der TechnikState of the art

Bei Gattersägen mit in einem Gatterrahmen eingespannten Sägeblättern wird das üblicherweise über einen Schubkurbeltrieb angetriebene Sägegatter mit Hilfe von Gleitstücken in seitlichen Führungsschienen eines Gestells gelagert, wobei die Möglichkeit besteht, die Schubstangen des Schubkurbeltriebes entweder im Bereich des dem Schubkurbeltrieb näheren oder entfernteren der beiden Streckbalken am Gatterrahmen anzulenken, zwischen denen die Sägeblätter eingespannt werden. Die Verbindung der Schubstangen mit dem näheren dieser Streckbalken bringt nicht nur eine bessere Zugänglichkeit zum Sägegatter, sondern auch günstige Belastungsverhältnisse für den Gatterrahmen mit sich, wenn der Schnitthub in Richtung des näheren Streckbalkens erfolgt, weil in diesem Fall die die Streckbalken verbindenden Längsholme des Gatterrahmens während des Schnitthubes auf Zug belastet werden. Trotz dieser konstruktiven Voraussetzungen für eine vergleichsweise leichte Bauweise bleibt die erreichbare Hubfrequenz beschränkt. Mit der Steigerung der Hubfrequenz steigen nämlich die Massenkräfte und damit die Führungsbelastungen überproportional an.In gate saws with saw blades clamped in a gate frame, the saw gate usually driven by a slider drive is mounted by means of sliders in lateral guide rails of a frame, with the possibility of the push rods of the slider crank drive either in the vicinity of the sliding frame closer or farther of the two extension bars on the gate frame to steer, between which the saw blades are clamped. The compound of the push rods with the closer of these stretch bars brings not only better accessibility to the saw gate, but also favorable loading conditions for the gate frame with him, when the cutting stroke in the direction of the closer draw bar, because in this case the longitudinal beams connecting the stretch bars of the gate frame during of the cutting stroke are loaded on train. Despite these constructive requirements for a comparatively light construction the achievable stroke frequency remains limited. With the increase in the stroke frequency, namely the mass forces and thus the leadership loads increase disproportionately.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt somit die Aufgabe zugrunde, eine Gattersäge der eingangs geschilderten Art so auszugestalten, daß eine merkliche Steigerung der Hubfrequenz des Sägegatters erreicht werden kann, ohne eine Überlastung der Führungen des Sägegatters befürchten zu müssen. Außerdem soll ein Wechsel des Gatterrahmens mit einem geringen Umbauaufwand vorgenommen werden können.The invention is therefore based on the object, a gate saw of the type described in such a way that a significant increase in the stroke frequency of the saw gate can be achieved without having to fear overloading the guides of the saw gate. In addition, a change of the gate frame with a small conversion effort should be made.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die beiden Schubstangen des Schubkurbeltriebes an einem gemeinsamen Querträger zur Aufnahme des Gatterrahmens im Bereich des dem Schubkurbeltrieb näheren der beiden Streckbalken angreifen, daß der Querträger mit Hilfe von Führungen auf den seitlichen Führungsschienen lagert und daß der Querträger gegenüber seinen Führungen um eine zu den Führungsschienen und dem Querträger senkrechte Achse verschwenkbar gehalten ist.The invention solves the problem set by the fact that the two push rods of the slider crank drive on a common cross member for receiving the gate frame in the vicinity of the crank drive closer of the two stretch bars attack that the cross member supports by means of guides on the side guide rails and that the cross member opposite his guides is held pivotable about an axis perpendicular to the guide rails and the cross member.

Da zufolge dieser Maßnahmen die Krafteinleitung vom Schubkurbeltrieb auf den Gatterrahmen über einen die beiden seitlichen Schubstangen des Schubkurbeltriebes miteinander verbindenden Querträger erfolgt, der auf den seitlichen Führungsschienen mit Hilfe von Führungen gelagert ist und diesen Führungen gegenüber um eine zu den Führungsschienen und dem Querträger senkrechte Achse verschwenkbar gehalten wird, können diese Führungen von sonst unvermeidlichen Drehmomentbelastungen entlastet werden. Im Bereich des vom Schubkurbeltrieb entfernteren Streckbalkens treten diese durch den Schubstangenangriff bedingten Drehmomente nicht auf, so daß der Gatterrahmen im Bereich des entfernteren Streckbalkens unmittelbar ohne gelenkige Verbindung über entsprechende Führungen auf den Führungsschienen gelagert werden kann.Since, according to these measures, the introduction of force from the slider crank drive on the gate frame via a the two lateral push rods of the sliding crank drive interconnecting cross member, which is mounted on the lateral guide rails by means of guides and these guides against a vertical axis to the guide rails and the cross member pivotable held, these guides can be relieved of otherwise unavoidable torque loads. In the area of the drawbar remote from the drawbar these torques caused by the push rod engagement do not occur, so that the gate frame can be stored in the region of the remainder of the extension bar directly without articulated connection via corresponding guides on the guide rails.

Um einerseits die Schnittgeschwindigkeit und anderseits die Schnittgenauigkeit zu verbessern, können die Führungen für den Querträger und den Grundrahmen im Bereich des vom Schubkurbeltrieb entfernteren Streckbalkens als Kugelumlaufführungen ausgebildet sein, die eine weitgehend spielfreie Verschiebeführung des Sägegatters ermöglichen, was außerdem zu einer Verlängerung der Standzeit der Sägeblätter führt.On the one hand to improve the cutting speed and on the other hand, the cutting accuracy, the guides for the cross member and the base frame in the area of the drawframe remote from the drawbar be designed as recirculating ball guides that allow a largely play-free sliding guide the saw gate, which also leads to an extension of the service life of the saw blades leads.

Der für sich auf den seitlichen Führungsschienen gelagerte, an den Schubkurbeltrieb angeschlossene Querträger erlaubt nicht nur eine günstige Krafteinleitung in den Gatterrahmen, sondern bringt auch einfache Auswechselbedingungen für das Sägegatter mit sich, weil zum Abnehmen des Gatterrahmens nicht die Antriebsverbindung zwischen dem Querträger und dem Schubkurbeltrieb gelöst werden muß. Günstige Konstruktionsbedingungen ergeben sich in diesem Zusammenhang, wenn der Querträger in eine Aufnahmenut des dem Schubkurbeltrieb näheren Streckbalkens eingesetzt ist, weil in diesem Fall der Gatterrahmen nach einem Lösen seiner Verbindung mit den Führungen im Bereich des dem Schubkurbeltrieb entfernteren Streckbalkens lediglich aus der Aufnahmenut zu heben ist. Die spielfreie Aufnahme des Querträgers in der Aufnahmenut des Streckbalkens kann vorteilhaft dadurch erreicht werden, daß die Aufnahmenut des Streckbalkens gegen den Nutgrund konvergierende Nutwände aufweist, an die sich der Querträger mit entsprechend geneigten Gegenflächen anlegt, sobald der Querträger z.B. mit Hilfe von Befestigungsschrauben gegen den Nutgrund der Aufnahmenut gezogen wird.The mounted on the side guide rails, connected to the sliding crank cross member not only allows a favorable force in the gate frame, but also brings easy replacement conditions for the saw with him, because not removed for removing the gate frame, the drive connection between the cross member and the sliding crank must become. Favorable design conditions arise in this context, when the cross member is inserted into a receiving groove of the slider crank drawbar, because in this case the gate frame is only to lift from the receiving groove after releasing its connection with the guides in the region of the push-crank drive more distant drawbar , The play-free recording of the cross member in the receiving groove of the extension beam can be advantageously achieved in that the receiving groove of the extension beam has against the groove bottom converging groove walls on which the cross member with correspondingly inclined mating surfaces applies, as soon as the cross member. is pulled with the aid of fastening screws against the groove bottom of the receiving groove.

Weg zur Ausführung der ErfindungWay to carry out the invention

Die dargestellte Gattersäge weist ein Gestell 1 auf, in dem ein Schubkurbeltrieb 2 zum Antrieb eines Sägegatters 3 gelagert ist. Das entlang seitlicher Führungsschienen 4 verschiebbare Sägegatter 3 umfaßt einen Gatterrahmen 5 mit zwei durch Längsholme miteinander verbundenen Streckbalken 6, 7, zwischen denen die Sägeblätter 8 eingespannt sind. Während der Gatterrahmen 5 im Bereich des dem Schubkurbeltrieb 2 entfernteren Streckbalkens 7 unmittelbar mit Führungen 9 für die seitlichen Führungsschienen 4 lösbar verbunden ist, lagert der Gatterrahmen 5 im Bereich des gegenüberliegenden, dem Schubkurbeltrieb 2 näheren Streckbalkens 6 auf einem Querträger 10, der axial vorstehende Anlenkzapfen 11 für seitliche Schubstangen 12 des Schubkurbeltriebes 2 trägt. Der Querträger 10 wird in einer Aufnahmenut 13 des Streckbalkens 6 gehalten. Da die Nutwände der Aufnahmenut 13 gegen den Nutgrund hin konvergieren und der Querträger 10 entsprechend geneigte Gegenflächen 14 bildet, greift der Querträger 10 spielfrei in die Aufnahmenut 13 ein, wenn der Querträger 10 mit Hilfe von Befestigungsschrauben gegen den Nutgrund gezogen wird.The gate saw shown has a frame 1, in which a sliding crank drive 2 is mounted for driving a sawing gate 3. The sliding along side guide rails 4 Sägegatter 3 comprises a gate frame 5 with two interconnected by longitudinal beams stretching beams 6, 7, between which the saw blades 8 are clamped. While the gate frame 5 is detachably connected directly to guides 9 for the lateral guide rails 4 in the region of the draw-bar drive 2, the gate frame 5 rests in the region of the opposite draw bar 6 closer to the draw bar 6 on a cross member 10, the axially projecting pivot pin 11 for lateral push rods 12 of the sliding crank drive 2 carries. The cross member 10 is held in a receiving groove 13 of the draw bar 6. Since the groove walls of the receiving groove 13 converge towards the bottom of the groove and the cross member 10 correspondingly inclined mating surfaces 14, the cross member 10 engages without play in the receiving groove 13 when the cross member 10 is pulled by means of fastening screws against the groove bottom.

Der Querträger 10.wird über Führungen 15 entlang der seitlichen Führungsschienen 4 geführt, so daß sich auch im Bereich des dem Schubkurbeltrieb 2 näheren Streckbalkens 6 eine entsprechende Verschiebbarkeit des Gatterrahmens 5 entlang der seitlichen Führungsschienen 4 ergibt. Die Verbindung zwischen dem Querträger 10 und den Führungen 15 ist jedoch nicht starr, um Drehmomentbelastungen der Führungen 15 bei einer Biegung des Querträgers 14 hintanhalten zu können. Aus diesem Grunde erfolgt die Befestigung des Querträgers 10 auf den Führungen 15 über Achsen 16, die senkrecht zu der jeweiligen Führungsschiene 4 und zum Querträger 10 verlaufen. Mit einer solchen Anlenkung des Querträgers 10 an den zugehörigen Führungen 15 bleibt die Gleitführung für den Gatterrahmen 5 weitgehend frei von Zwangskräften, die sich nachteilig auf die Führungsgenauigkeit auswirken könnten, so daß durch diese Konstruktion vorteilhafte Voraussetzungen für eine Erhöhung der Hubfrequenz des Sägegatters 3 erfüllt werden, zumal sich eine gewichtssparende Bauweise ergibt, ohne die Auswechselbarkeit des Sägegatters 3 zu beeinträchtigen. Zum Lösen des Gatterrahmens 5 sind ja lediglich die Verbindungen des Gatterrahmens 5 einerseits mit den Führungen 9 und anderseits mit dem Querträger 10 zu lösen, was mit wenig Zeit- und Arbeitsaufwand durchgeführt werden kann.The cross member 10 is guided over guides 15 along the lateral guide rails 4, so that there is a corresponding displaceability of the gate frame 5 along the lateral guide rails 4 in the region of the drawbar crank 2 closer draw bar 6. However, the connection between the cross member 10 and the guides 15 is not rigid in order to withhold torque loads of the guides 15 at a bend of the cross member 14 can. For this reason, the attachment of the cross member 10 on the guides 15 via axes 16, which are perpendicular to the respective guide rail 4 and the cross member 10. With such an articulation of the cross member 10 to the associated guides 15, the sliding guide for the gate frame 5 remains largely free of constraining forces that could adversely affect the guidance accuracy, so that advantageous conditions for increasing the Stroke frequency of the saw gate 3 are met, especially since a weight-saving design results without affecting the interchangeability of the saw gate 3. To release the gate frame 5 so only the connections of the gate frame 5 are on the one hand with the guides 9 and on the other hand to solve with the cross member 10, which can be done with little time and effort.

Obwohl die Führungen 9, 15 für den Gatterrahmen 5 im Bereich des vom Schubkurbeltrieb entfernteren Streckbalkens 7 einerseits und den Querträger 10 anderseits auch als Gleitführungen ausgebildet sein können, ergeben sich hinsichtlich der Führungsgenauigkeit des Gatterrahmens 5 günstigere Bedingungen durch den Einsatz von Kugelumlaufführungen, was sich vorteilhaft auf die Schnittgenauigkeit, die erreichbare Schnittgeschwindigkeit und darüber hinaus auf die Standzeit der Sägeblätter auswirkt.Although the guides 9, 15 for the gate frame 5 in the region of the drawbar remote drive beam 7 on the one hand and the cross member 10 on the other hand can be designed as sliding guides arise with regard to the accuracy of the gate frame 5 more favorable conditions through the use of recirculating ball bearings, which is advantageous on the cutting accuracy, the achievable cutting speed and beyond on the service life of the saw blades.
