Es sind Fräser zur Bearbeitung von Rundholz bekannt, bei denen die Fräser auf zwei Wellenpaaren angeordnet sind, bei denen die axiale Fräserlänge und damit die zu erzeugende spätere Brettdicke durch die Fräserbreite vorgegeben ist. Diese Anordnungen haben den Nachteil, daß ohne Umrüstung immer die gleichen Bretter geschnitten werden müssen.There are milling cutters for processing round wood in which the cutters are arranged on two pairs of shafts, in which the axial cutter length and thus the subsequent board thickness to be produced is determined by the cutter width. These arrangements have the disadvantage that the same boards always have to be cut without retooling.
Der Erfindung liegt die Aufgabe zugrunde, ein Fräsersystem zu schaffen, das aus einem Rundholz ein Polygonprofil fräst, das in seinen Stufenbreiten stufenlos verstellbar ist und in Sonderausführung ebenfalls in der Stufenhöhe insgesamt stufenlos veränderbar ist.The invention is based on the object of creating a milling system that mills a polygonal profile from a round piece of wood, the step widths of which are infinitely adjustable and, in a special design, the step height can also be infinitely adjusted.
Das erfindungsgemäße Fräseraggregat besteht aus mindestens zwei, vorzugsweise vier Sätzen von Fräsern unterschiedlicher Durchmesser, die auf Wellen angeordnet sind, die axial zueinander verstellbar sind und insgesamt axial verschiebbar sind. Durch die topfförmige Ausbildung der Fräser können diese axial ineinander geschoben werden, so daß durch völliges Hereinfahren einzelner Fräser einzelne Frässtufen verschwinden können.The milling unit according to the invention consists of at least two, preferably four sets of milling cutters of different diameters, which are arranged on shafts that are axially adjustable relative to one another and are axially displaceable overall. Due to the pot-shaped design of the milling cutters, they can be pushed axially into one another, so that individual milling stages can disappear by completely retracting individual milling cutters.
Eine weitere Sonderausführung weist aussen konische Fräser auf mit großem Durchmesser, so daß aus dem Rundprofil ein vollständiges rechteckiges Polygonprofil fräsbar ist, unabhängig vom Stammdurchmesser.Another special design has conical cutters with a large diameter on the outside, so that a complete rectangular polygon profile can be milled from the round profile, regardless of the trunk diameter.

Die Achsen der vier Fräsaggregate können in der unteren Anordnung coaxial sein und die beiden oberen Achsen ebenfalls, jedoch um einen Betrag in Vorschubrichtung versetzt. Eine Sonderausführung weist auch in den beiden Achsebenen einen horizontalen Versatz der Achsen auf, wodurch es möglich ist, mittels der inneren Fräser mit kleinem Durchmesser, die eine konstante Länge haben, horizontale Flächen anzufrasen mit stufenlos veränderbarer Breite.The axes of the four milling units can be coaxial in the lower arrangement and the two upper axes can also be coaxial, but offset by a certain amount in the feed direction. A special version also has a horizontal offset of the axes in the two axis planes, which makes it possible to mill horizontal surfaces with a continuously variable width using the small-diameter inner milling cutters, which have a constant length.
Eine weitere Sonderausführung weist eine Kombination von Sägeblättern und erfindungsgemäßen Fräsern auf, wodurch es ermöglicht ist, das stufenlos veränderbare Polygonprofil entsprechend dieser Abstufung in Bretter oder Balken aufzutrennen.Another special design has a combination of saw blades and milling cutters according to the invention, which makes it possible to split the continuously variable polygon profile into boards or beams according to this gradation.
Der vertikale Achsabstand der beiden oberen und unteren Fräsaggregate kann dadurch erfolgen, daß die gesamte Maschine um eine Achse geschwenkt wird, die parallel zu den Fräsaggregatachsen liegt.The vertical axis distance of the two upper and lower milling units can be adjusted by swiveling the entire machine around an axis that is parallel to the milling unit axes.
Figur 1 zeigt vier Fräsaggregate mit der axial verstellbaren äusseren Welle (1), auf der der äussere zylindrische Fräser (4) und der äussere konische Fräser (7) befestigt sind, die in ihrem Achsabstand durch Zwischenringe einstellbar sind. Aus der äusseren Welle (1) ist die mittlere Welle (2) herausfahrbar, auf der der mittlere Fräser (5) befestigt ist. Aus dieser mittleren Welle (2) istFigure 1 shows four milling units with the axially adjustable outer shaft (1), on which the outer cylindrical milling cutter (4) and the outer conical milling cutter (7) are attached, the axial distance of which can be adjusted using intermediate rings. The middle shaft (2) on which the middle milling cutter (5) is attached can be moved out of the outer shaft (1). From this middle shaft (2)

wiederum die innere Welle (3) herausfahrbar, auf der der innere Fräser (6) befestigt ist, wobei die Fräser (4, 5 und 6) durch ihre Topfform soweit ineinander schiebbar sind, daß sie jeweils im benachbarten Fräser verschwinden können.The inner shaft (3) on which the inner cutter (6) is attached can be moved out again, whereby the cutters (4, 5 and 6) can be pushed into one another due to their cup shape so that they can each disappear into the adjacent cutter.
Mit dem inneren Fräser (6) ist coaxial der Vorsatzfräser (8) verbunden, der mit seiner Achse horizontal gegenüber dem Vorsatzfräser auf der gegenüberliegenden Seite um mindestens seinen Durchmesser versetzt ist.The front milling cutter (8) is coaxially connected to the inner milling cutter (6), the axis of which is horizontally offset by at least its diameter relative to the front milling cutter on the opposite side.
Figur 2 zeigt eine Sonderausführung der erfindungsgemäßen Fräser mit der äusseren Welle (1), dem mittleren Fräser (5) und dem äusseren zylindrischen Fräser (4), dessen Kontur etwas kleiner ist als die Mittenausnehmung des äusseren Sägeblattes (10), das mittels äusserer Schrauben (12) mit dem äusseren zylindrischen Fräser (4) verbunden ist und das äussere Sägeblatt durch kleine Vorsprünge coaxial positioniert.Figure 2 shows a special design of the milling cutter according to the invention with the outer shaft (1), the middle milling cutter (5) and the outer cylindrical milling cutter (4), the contour of which is slightly smaller than the central recess of the outer saw blade (10), which is connected to the outer cylindrical milling cutter (4) by means of external screws (12) and positions the outer saw blade coaxially by means of small projections.
Figur 3 zeigt den Schnitt A-A der Figur 2, jedoch mit einem zusätzlichen inneren Sägeblatt (11), das mittels innerer Schrauben (13) gegen die mittleren Fräser (5) gedrückt und positioniert ist und die Distanzscheibe (9) eine Veränderung der axialen Wirklänge des mittleren Fräsers (5) bewirkt, indem dieser Fräser in die Innenkontur des äusseren Fräsers (4) schiebbar ist und von dieser Innenkontur Spanabfuhrlöcher (4.1) nach aussen gehen.Figure 3 shows the section A-A of Figure 2, but with an additional inner saw blade (11) which is pressed and positioned against the middle cutters (5) by means of inner screws (13) and the spacer disk (9) causes a change in the axial effective length of the middle cutter (5) by allowing this cutter to be pushed into the inner contour of the outer cutter (4) and chip removal holes (4.1) leading outwards from this inner contour.
