Hierdurch ist sichergestellt, dass der Biegestempel ausschließlich an der Biegestelle des Drahts angreift und nicht etwa z.B. am Anfang des Biegevorgangs bis zur Biegestelle am Draht entlangrutscht.This ensures that the bending punch engages exclusively at the bending point of the wire and not, e.g. at the beginning of the bending process slips along the wire to the bending point.
Unvorteilhafterweise startet bei bekannten Biegevorrichtungen eine Bewegung der zweiten Klemmeinheit in Vorschubrichtung asynchron, mit einem zeitlichen Versatz, oder mit unterschiedlichen Beschleunigungen zu einer Biegebewegung des Biegestempels, z.B. aufgrund unterschiedlicher Signallängen oder aufgrund unterschiedlicher Antriebe. So kann die Vorschubeinrichtung z.B. durch einen Elektromotor antreibbar ausgestaltet sein und der Biegestempel z.B. durch eine Pneumatik. Sowohl die Vorschubeinheit, als auch der Biegestempel kann von einem elektrischen, hydraulischen und/oder pneumatischen Antrieb angetrieben sein. Durch die Positionierung des Biegestempels vor dem Start des Biegevorgangs in der vorteilhaften Ausgestaltung der Erfindung ist dieser zeitliche und/oder räumliche Versatz kompensierbar.Unfavorably, in known bending devices, a movement of the second clamping unit in the feed direction starts asynchronous, with a time offset, or with different accelerations to a bending movement of the punch, eg due to different signal lengths or due to different drives. Thus, the feed device can be designed to be drivable, for example, by an electric motor and the punch, for example, by a pneumatic. Both the feed unit, as well as the punch can be driven by an electric, hydraulic and / or pneumatic drive. By positioning the bending punch before the start of the bending operation in the advantageous embodiment of the invention, this temporal and / or spatial offset can be compensated.
Bevorzugterweise ist ein senkrechter Abstand der Biegefläche zur Biegestelle einstellbar. Wobei unter einem senkrechten Abstand ein Abstand der Biegefläche zur Biegestelle senkrecht zur Vorschubrichtung in einer Bewegungsebene, welche die zweiten Klemmeinheit und der Biegestempel aufspannen, gemeint ist.Preferably, a vertical distance of the bending surface to the bending point is adjustable. Wherein at a vertical distance, a distance of the bending surface to the bending point perpendicular to the feed direction in a plane of movement, which span the second clamping unit and the punch, is meant.
In einer weiteren vorteilhaften Ausführung der Erfindung ist der Biegestempel derart schwenkbar am Maschinenrahmen anordenbar und positionierbar, sodass vor dem Start eines Biegevorgangs ein Abstand der Biegefläche zu einer Biegestelle des Drahts einen vorgegebenen Wert nicht überschreitet.In a further advantageous embodiment of the invention, the bending punch is pivotable on the machine frame can be arranged and positioned so that before the start of a bending operation, a distance of the bending surface to a bending point of the wire does not exceed a predetermined value.
Hierdurch ist z.B. sichergestellt, dass die Biegefläche des Biegestempels nicht an der Biegefläche angreift, bevor der Draht in Vorschubrichtung, bspw. durch die zweite Klemmeinheit, bewegt wird.This is e.g. ensures that the bending surface of the punch does not attack the bending surface before the wire in the feed direction, for example. By the second clamping unit is moved.
Der vorgegebene Wert kann abhängig von einer Winkelstellung der Längsachse des Biegestempels zur Vorschubrichtung ausgebildet sein, insbesondere von der Winkelstellung vor dem Start des Biegevorgangs.The predetermined value may be formed depending on an angular position of the longitudinal axis of the punch to the feed direction, in particular of the angular position before the start of the bending operation.
Der vorgegebene Wert des Abstands der Biegefläche zur Biegestelle vor dem Start des Biegevorgangs liegt beispielsweise in einem Bereich zwischen 0,1 mm bis 2 mm, 0,2 mm bis 1,5 mm und/oder 0,5 mm bis 1 mm. Der vorgegebene Abstandswert beträgt z.B. 0,1 mm, 0,2 mm, 0,3 mm, 0,4 mm, 0,6 mm, 0,7 mm, 0,8 mm, 0,9 mm oder 1 mm, insbesondere 0,5 mm.The predetermined value of the distance of the bending surface to the bending point before the start of the bending process is for example in a range between 0.1 mm to 2 mm, 0.2 mm to 1.5 mm and / or 0.5 mm to 1 mm. The predetermined distance value is, for example, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm, in particular 0 , 5 mm.
Bevorzugterweise ist der Biegestempel mit einem zweiten Ende in einer Richtung parallel zur Vorschubrichtung des Drahts und/oder parallel zur Längsachse des umgebogenen Drahts verschiebbar am Maschinenrahmen anordenbar. Beispielsweise umfasst die Biegevorrichtung eine Verstelleinrichtung zum linearen Verstellen des Biegestempels parallel zur Vorschubrichtung des Drahts und/oder parallel zur Längsachse des umgebogenen Drahts. Insbesondere ist der Biegestempel über die Verstelleinrichtung am Maschinenrahmen befestigbar. Die Verstelleinrichtung ist beispielsweise als Schlitten ausgebildet, welcher parallel zur Vorschubrichtung verfahrbar und/oder positionierbar am Maschinenrahmen anordenbar ist.Preferably, the bending punch with a second end in a direction parallel to the feed direction of the wire and / or parallel to the longitudinal axis of the bent wire slidably on the machine frame can be arranged. For example, the bending device comprises an adjusting device for linear adjustment of the bending punch parallel to the feed direction of the wire and / or parallel to the longitudinal axis of the bent wire. In particular, the bending punch can be fastened to the machine frame via the adjusting device. The adjusting device is designed, for example, as a carriage, which can be arranged movable and / or positionable on the machine frame parallel to the feed direction.
Als vorteilhaft erweist sich auch, dass die Verschiebeeinheit in einer Richtung senkrecht zur Biegestrecke oder zur Vorschubrichtung des Drahts verstellbar am Maschinenrahmen und/oder der zweiten Klemmeinheit anordenbar ist.It proves to be advantageous that the displacement unit in an adjustable direction perpendicular to the bending path or to the feed direction of the wire on the machine frame and / or the second clamping unit can be arranged.
Bevorzugterweise ist die Verschiebeeinheit in einer Richtung senkrecht zur Vorschubrichtung versetzbar ausgebildet. Vorteilhafterweise ist ein Abstand zwischen der zweiten Klemmeinheit und der Verschiebeeinheit insbesondere in einer Richtung senkrecht zur Vorschubrichtung des Drahts in der Bewegungsebene der zweiten Klemmeinheit und des Biegestempels einstellbar.Preferably, the displacement unit is designed to be displaceable in a direction perpendicular to the feed direction. Advantageously, a distance between the second clamping unit and the displacement unit is adjustable in particular in a direction perpendicular to the feed direction of the wire in the plane of movement of the second clamping unit and the bending punch.
Weiterhin erweist sich als vorteilhaft, dass die Biegefläche, über welche der Draht verläuft, zu einer Längsachse B des Biegestempels in Richtung der erster Klemmeinheit versetzt am ersten Ende des Biegestempels angeordnet ist.Furthermore, it proves to be advantageous that the bending surface over which the wire extends is offset relative to a longitudinal axis B of the bending punch in the direction of the first clamping unit at the first end of the bending punch.
Hierdurch kann in einem Biegevorgang die Biegefläche, insbesondere am Ende des Biegevorgangs, eine Position über der ersten Klemmeinheit, senkrecht zur Vorschubrichtung gesehen, einnehmen. Vorteilhafterweise ist die Biegefläche derart am Biegestempel vorhanden, dass die Biegefläche während des Biegevorgangs, insbesondere am Ende des Biegevorgangs eine Position einnimmt, welche weiter von einer Klemme der zweiten Klemmeinheit beabstandet ist, als die Klemme der ersten Klemmeinheit.As a result, in a bending operation, the bending surface, in particular at the end of the bending process, occupy a position above the first clamping unit, viewed perpendicular to the feed direction. Advantageously, the bending surface is provided on the bending punch in such a way that the bending surface, during the bending operation, in particular at the end of the bending operation, assumes a position which is farther from a clamp of the second clamping unit than the clamp of the first clamping unit.
Bevorzugterweise ist in Vorschubrichtung gesehen ein Abstand der Biegefläche zur Klemme der ersten Klemmeinrichtung kleiner, als ein Abstand des Drehlagers des Schwenkarms zur Klemme der ersten Klemmeinrichtung.Preferably, seen in the feed direction, a distance of the bending surface to the terminal of the first clamping device is smaller than a distance of the pivot bearing of the pivot arm to the terminal of the first clamping device.
Auch erweist sich als vorteilhaft, dass der Schwenkarm mit seinem ersten Ende schwenkbar an der Verschiebeeinheit und mit seinem, dem ersten Ende gegenüberliegend ausgebildetem, zweitem Ende schwenkbar am ersten Ende des Biegestempels angeordnet ist.Also, it proves to be advantageous that the pivot arm is pivotally mounted with its first end to the displacement unit and with its, the first end formed opposite, second end pivotally mounted on the first end of the punch.
Beispielsweise ist der Schwenkarm an einem ersten Drehlager dreh- bzw. schwenkbar mit der Verschiebeeinheit verbunden und an einem zweiten Drehlager mit dem Biegestempel.For example, the pivot arm is rotatably connected to a first pivot bearing or pivotally connected to the displacement unit and to a second pivot bearing with the bending punch.
Weiterhin ist vorteilhaft, dass ein Abstand einer ersten Schwenkachse des Schwenkarms an der Verschiebeeinheit und einer zweiten Schwenkachse des Schwenkarms am ersten Ende des Biegestempels konstant ist. Vorteilhafterweise sind Schwenkachsen und/oder Rotationsachsen der beiden Drehlager zueinander fest beabstandet.Furthermore, it is advantageous that a distance between a first pivot axis of the pivot arm on the displacement unit and a second pivot axis of the pivot arm at the first end of the bending punch is constant. Advantageously, pivot axes and / or rotational axes of the two pivot bearings are mutually firmly spaced.
Überdies ist es vorteilhaft, dass die Biegefläche am Schwenkarm vorhanden ist.Moreover, it is advantageous that the bending surface is present on the swivel arm.
Vorteilhafterweise ist die Biegefläche am Schwenkarm befestigt, z.B. angeschraubt und/oder angeschweißt. Beispielsweise bildet die Biegefläche eine Verlängerung des Schwenkarms insbesondere in Richtung der ersten Klemmeinheit.Advantageously, the bending surface is attached to the pivot arm, for example screwed and / or welded. For example, the bending surface forms an extension of the pivot arm, in particular in the direction of the first clamping unit.
Weiter wird vorgeschlagen, dass der Schwenkarm L-förmig ausgebildet ist.It is further proposed that the pivot arm is L-shaped.
Beispielsweise ist die erste Schwenkachse des Schwenkarms am ersten Ende eines langen Zweigs des L-förmigen Schwenkarms ausgebildet und die zweite Schwenkachse an einer Schnittstelle des langen Zweigs des L-förmigen Schwenkarms mit einem kurzen Zweig des L-förmigen Schwenkarms. Die Schnittstelle ist dem ersten Ende des langen Zweigs gegenüberliegend vorhanden. Wobei an der zweiten Schwenkachse der Biegestempel drehbar und/oder schwenkbar angeordnet ist. Eine Längsachse des langen und eine Längsachse des kurzen Zweigs des L-förmigen Schwenkarms stehen vorteilhafterweise in einem Winkel ungleich 0° zueinander. An dem, der Schnittstelle gegenüberliegenden Ende des kurzen Zweigs des L-förmigen Schwenkarms ist vorteilhafterweise die Biegefläche vorhanden. Beispielsweise ist der Schwenkarm abgeknickt und/oder abgewinkelt ausgebildet. Z.B ist der Schwenkarm derart ausgebildet, dass in einer Endposition des Biegevorgangs der Schwenkarm die erste Klemmeinheit auf der, der zweiten Klemmeinheit abgewandten Seite hintergreift. Insbesondere, dass die z.B. am Schwenkarm vorhandene Biegefläche die erste Klemmeinheit, vorteilhafterweise die Klemme der ersten Klemmeinheit hintergreift.For example, the first pivot axis of the pivot arm is formed at the first end of a long branch of the L-shaped pivot arm and the second pivot axis at an interface of the long branch of the L-shaped pivot arm with a short branch of the L-shaped pivot arm. The interface is present opposite the first end of the long branch. Wherein the bending punch is rotatably and / or pivotally mounted on the second pivot axis. A longitudinal axis of the long and a longitudinal axis of the short branch of the L-shaped pivot arm are advantageously at an angle not equal to 0 ° to each other. At the, the interface opposite end of the short branch of the L-shaped pivot arm advantageously the bending surface is present. For example, the swivel arm is bent and / or angled. For example, the swivel arm is designed such that in an end position of the bending operation, the swivel arm engages behind the first clamping unit on the side facing away from the second clamping unit. In particular, that the bending surface present on the swivel arm, for example, engages behind the first clamping unit, advantageously the clamp of the first clamping unit.

Eine erfindungsgemäße Biegevorrichtung 1 zum Biegen eines Biegedrahts 11, 12 umfasst eine erste Klemmeinheit 2, eine zweite Klemmeinheit 3, einen Biegestempel 4 und eine Verschiebeeinheit 5 mit einem Schwenkarm 6 (
Die Biegevorrichtung 1 ist an einen Rahmen 7 einer Gitterträgerschweißmaschine 8 anordenbar (
Zwischen der ersten und der zweiten Klemmeinheit 2, 3 erstreckt sich vorteilhafterweise eine Biegestrecke entlang der Vorschubrichtung V. Beispielsweise erstreckt sich die Biegestrecke zwischen einer Klemme 25 der ersten Klemmeinheit 2 und einer weiteren Klemme 26 der zweiten Klemmeinheit 3. Die Biegestrecke ist somit entlang der Vorschubrichtung V zwischen den beiden Klemmeinheiten 2, 3 zu sehen und entspricht insbesondere nicht einer Strecke die eine Biegestelle 23, 24 des Biegedrahts 11, 12 während eines Biegevorgangs in einer Richtung senkrecht zur Vorschubrichtung V des Biegedrahts 11, 12 zurücklegt. Als Biegestrecke ist damit der Bereich entlang der Vorschubrichtung V zu sehen, in welchem der Biegedraht 11, 12 gebogen wird. Dieser Bereich verringert bzw. verkleinert sich während des Biegevorgangs von einer Biegestartposition der zweiten Klemmeinheit 3 in eine Biegeendposition der zweiten Klemmeinheit 3. Die Klemmen 25 und 26 der beiden Klemmeinheiten 2, 3 klemmen während des Biegevorgangs den Biegedraht 11, 12 und halten den Biegedraht 11, 12 jeweils an einer Klemmstelle der Klemmen 25, 26 an den Klemmeinheiten 2, 3 fest. In den Figuren ist die Klemme 26 der Klemmeinheit 3 zum besseren Verständnis transparent dargestellt.For example, the bending path extends between a
Vorteilhafterweise sind die Verschiebeeinheit 5 und die zweite Klemmeinheit 3 insbesondere mechanisch unabhängig voneinander versetzbar am Rahmen 7 vorhanden. Denkbar ist aber auch, dass die zweite Klemmeinheit 3 versetzbar am Rahmen 7 vorhanden ist und die Verschiebeeinheit 5 relativ zur zweiten Klemmeinheit 3 positionierbar an der zweiten Klemmeinheit 3 ausgebildet ist. In diesem Fall ist es vorstellbar, dass die Verschiebeeinheit 5 über ein Schienenelement 14 am Rahmen 7 bspw. zusätzlich geführt ist.Advantageously, the
Der Biegestempel 4 umfasst zwei bspw. hydraulische Biegezylinder 18, 19. In jeweils einem Biegezylinder 18, 19 ist ein Biegekolben 20, 21 insbesondere linear verschiebbar vorhanden. Die Biegezylinder 18, 19 sind außerdem derart zueinander beabstandet vorhanden, dass in einem Biegevorgang die zweite Klemmeinheit 3 zwischen die Biegezylinder 18, 19 verschoben werden kann.The bending
Der Biegestempel 4 ist mit einem zweiten Ende 15 am Rahmen 7 der Gitterträgerschweißmaschine 8 schwenkbar, insbesondere positionierbar angeordnet. Vorteilhafterweise ist der Biegestempel 4 derart an der Gitterträgerschweißmaschine 8 angeordnet, sodass er vor einem Biegevorgang mit seinem zweiten Ende 15 insbesondere in einer Richtung parallel zur Vorschubrichtung V des Biegedrahts 11, 12 am Rahmen 7 in eine Funktionsposition bringbar ist. Die Funktionsposition ist beispielsweise auf eine Geometrie des gebogenen Biegedrahtes 11, 12 abgestimmt. Hierdurch ist eine Geometrievielfalt des gebogenen Biegedrahts 11, 12 erhöht. Vorteilhafterweise ist durch die Positionierbarkeit des zweiten Endes 15 des Biegestempels 4 ein, insbesondere zur Vorschubrichtung senkrechter Abstand A einer Biegefläche 16, 17 der Biegevorrichtung 1 zu der Biegestelle 23, 24 des Biegedrahts 11, 12 in einer Biegestartposition der Biegevorrichtung 1 einstellbar (
Der Biegestempel 4 ist an seinem ersten Ende 22 mit Enden der Biegekolben 20, 21 über eine Schwenkachse 10 schwenkbeweglich mit dem Schwenkarm 6 verbunden. Durch die Lagerung des Biegestempels 4 mit dem zweiten Ende 15 am Rahmen 7 und dem ersten Ende 22 an der Schwenkachse 10 ist vorteilhafterweise eine Hauptkraftrichtung des Biegestempels 4 auf den Biegedraht 11, 12 senkrecht zur Vorschubrichtung V des Biegedrahts 11, 12 vorgegeben.The bending
Der Schwenkarm 6 ist über eine weitere Schwenkachse 9 schwenkbar, insbesondere drehbar mit der Verschiebeeinheit 5 verbunden. Die Schwenkachsen 9 und 10 sind voneinander fest beabstandet. Vorteilhafterweise ist der Schwenkarm 6 aus einem Stahlträger ausgebildet.The
Bewegt sich die Verschiebeeinheit 5 während des Biegevorgangs relativ zu der Klemme 25 der ersten Klemmeinheit 2 nicht, beschreibt die Biegefläche 16, 17 des Schwenkarms 6 während des Biegevorgangs vorteilhafterweise eine Kreisbahn, mit einem Kreisbahnradius, welcher dem direkten Abstand der Schwenkachse 9 zur Biegefläche 16 bzw. 17 entspricht.If the
Vorstellbar ist allerdings auch, dass sich ein Abstand der Verschiebeeinheit 5 relativ zur Klemme 25 der ersten Klemmeinheit 2 während des Biegevorgangs verändert. Denkbar ist bspw., dass der Abstand der Verschiebeeinheit 5 relativ zur Klemme 25 der ersten Klemmeinheit 2 sich während des Biegevorgangs von einer Startposition (
