Der Zuführförderer einer solchen Biegeanlage ist im allgemeinen ein Rollgang. Blockfahrt bezeichnet eine Bewegung, deren Endstellung durch eine Blockierung definiert ist. Die Biegemaschinen einer solchen Biegeanlage besitzen im allgemeinen einen Biegetisch und einen um eine vertikale Achse antreibbaren Biegeteller mit einem darauf angeordneten Biegewerkzeug, z.B. in Form eines Biegefingers, ein zentrales Biegegegenwerkzeug und einen Gegenhalter. Die beschriebenen Werkzeuge oder einige davon sind austauschbar, wenn es sich darum handelt, an Stahlstäben Abbiegungen mit unterschiedlichem Biegeradius anzubringen. Zugeordnet sind Biegetischleisten und ein Anschlag an der feststehend angeordneten Biegemaschine. Auch der Zuführförderer kann einen Anschlag aufweisen. Die Anschläge sind regelmäßig verstellbar und definieren die Endlagen der Stirnseiten der zu biegenden Stahlstäbe.The invention relates to a bending system for steel bars, in particular reinforcing steel bars, with a feed conveyor, bending machine unit and ejection device, the bending machine unit having a movable bending machine, a support device and a fixedly arranged bending machine and the movable bending machine in the longitudinal direction of the support device to the stationary bending machine and back and forth Block travel is movable.

The bending machines of such a bending installation generally have a bending table and a bending plate which can be driven about a vertical axis and a bending tool, e.g. in the form of a bending finger, a central bending counter tool and a counter holder. The tools described, or some of them, are interchangeable when it comes to making bends with different bending radius on steel bars.

Bei der aus der Praxis bekannten Biegeanlage, von der die Erfindung ausgeht, ist die Auflagereinrichtung als Tisch ausgeführt. Das ist problemlos, wenn es sich um das Biegen von einzelnen Stahlstäben handelt. Wenn mehrere Stahlstäbe gleichzeitig, in vertikaler Richtung übereinanderliegend, gebogen werden sollen, sind Stabstahlaufnahmen erforderlich, die dieses zulassen. Sie sind bei der bekannten Ausführungsform an den Tisch angeschlossen bzw. anschließbar. Stahlstäbe unterschiedlicher Länge verlangen an verschiedenen Positionen ihrer Länge entsprechende Stahlstabaufnahmen, die gleichzeitig auch eine Unterstützung bewirken. Die Stahlstabaufnahmen der bekannten Biegeanlage können nicht einfach auf das Biegen von Stahlstäben unterschiedlicher Länge eingerichtet werden. Insoweit ist die bekannte Anlage zum Einsatz in flexiblen Fertigungsstraßen verbesserungsfähig.In the bending system known from practice, from which the invention is based, the support device is designed as a table. This is no problem when it comes to bending individual steel bars. If several steel rods are to be bent at the same time, one above the other in the vertical direction, rod steel holders are required that allow this. In the known embodiment, they are connected or connectable to the table. Steel bars of different lengths require them in different positions Length corresponding steel rod mounts, which also provide support. The steel rod receptacles of the known bending system cannot simply be set up for bending steel rods of different lengths. In this respect, the known system for use in flexible production lines can be improved.
Der Erfindung liegt die Aufgabe zugrunde, eine Biegeanlage des eingangs beschriebenen Aufbaus so weiter auszubilden, daß sie einfach auf das Biegen von Stahlstäben unterschiedlicher Länge eingestellt werden kann.The invention has for its object to develop a bending system of the construction described above so that it can be easily adjusted to the bending of steel rods of different lengths.
Zur Lösung dieser Aufgabe lehrt die Erfindung, daß zwischen der verfahrbaren Biegemaschine und der feststehend angeordneten Biegemaschine zumindest eine in Längsrichtung dem Auflagereinrichtung verfahrbare Stützeinrichtung angeordnet ist, die einen Stützeinrichtungstisch, ein als schiefe Ebene ausgeführtes Einlaufelement, eine Stabstahlaufnahme für mehrere in vertikaler Richtung übereinanderliegende zu biegende Stahlstäbe und ein Abwurfelement aufweist, daß die Stützeinrichtung von der verfahrbaren Biegemaschine in Richtung auf die feststehende Biegemaschine bis in eine Blockfahrtstellung drückbar ist, daß die Stützeinrichtung aus der Blockfahrtstellung heraus über zumindest eine längeneinstellbares Zugmittel von der verfahrbaren Biegemaschine bis in vorgebbare Stützstellungen ziehbar ist und daß außerdem der Stützeinrichtungstisch sowie unabhängig davon die Aufnahmebreite der Stahlstabaufnahme quer zur Längsachse der Auflagereinrichtung verstellbar sind. Nach bevorzugter Ausführungsform der Erfindung sind entsprechende Stützeinrichtungen auflagereinrichtungsseitig auch an der verfahrbaren Biegemaschine sowie an der feststehenden Biegemaschine angeordnet. Diese Stützeinrichtungen können, bis auf das Stützeinrichtungsgestell, aus identisch gleichen Bauteilen bestehen wie die verfahrbare Stützeinrichtung, die vorstehend beschrieben wurde. Regelmäßig ist im Rahmen der Erfindung die Biegeanlage mit mehreren verfahrbaren Stützeinrichtungen ausgerüstet.To achieve this object, the invention teaches that between the movable bending machine and the fixedly arranged bending machine at least one support device which is movable in the longitudinal direction of the support device is arranged, which has a support device table, an inlet element designed as an inclined plane, and a steel bar holder for a plurality of steel bars to be bent one above the other in the vertical direction Steel rods and a discharge element has that the support device can be pressed from the movable bending machine in the direction of the stationary bending machine into a block travel position, that the support device can be pulled out of the block travel position via at least one length-adjustable traction means from the movable bending machine to predefinable support positions and that in addition, the support device table and independently of it the receiving width of the steel rod holder are adjustable transversely to the longitudinal axis of the support device. According to a preferred embodiment of the invention, corresponding support devices are also arranged on the support device side on the movable bending machine and on the stationary bending machine. Except for the support frame, these support devices can consist of identical components to the movable support device that was described above. Is regular within the scope of the invention, the bending system is equipped with a plurality of movable support devices.
Die erreichten Vorteile sind darin zu sehen, daß erfindungsgemäß zu biegende Stahlstäbe mit Hilfe der Stützeinrichtung beim Biegevorgang so gestützt werden könne, wie es zur Vermeidung eines störenden Durchhängens erforderlich ist. Von besonderem Vorteil ist die Tatsache, daß dabei ohne weiteres eine Einstellung auf unterschiedliche Biegewerkzeuge erforderlich ist, wenn Biegungen mit unterschiedlichem Biegeradius an die Stahlstäbe angebogen werden sollen. Dazu ist bei der erfindungsgemäßen Biegeanlage der Stützeinrichtungstisch in der beschriebenen Weise verstellbar. Die Stahlstabaufnahme ist in der beschriebenen Weise verstellbar, um unterschiedlichen Durchmessern der zu biegenden Stahlstäbe angepaßt zu werden. In der Stahlstabaufnahme können die zu biegenden Stahlstäbe auch festgeklemmt werden. besonderem Vorteil ist die Tatsache, daß das Verfahren der Stützeinrichtung nach Maßgabe der Länge der zu biegenden Stahlstäbe über die ohnehin verfahrbare Biegemaschine erfolgen kann. In diesem Zusammenhang kann das längeneinstellbare Zugmittel auf verschiedene Weise ausgebildet und längeneinstellbar sein. Eine bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß das längeneinstellbare Zugmittel auf eine Spule mit Rückstellfeder aufspulbar und die Abspullänge des Zugmittels einstellbar ist. Es versteht sich, daß bei der erfindungsgemäßen Biegeanlage die Übergabe der zu biegenden Stahlstäbe von dem Zuführförderer auf das Biegemaschinenaggregat einfach und zügig erfolgen muß, wie es im Rahmen einer flexiblen Fertigungsstraße üblich ist. Dazu lehrt die Erfindung, daß den Stützeinrichtungen ein Zuführförderer angeordnet ist, dessen Förderebene zum Zwecke der Übergabe der auf dem Zuführförderer nebeneinanderliegend angeordneten Stahlstäbe auf das Niveau des Einlaufelementes der Stützeinrichtung heb- bzw. senkbar ist. Dazu kann die Förderebene über Hebelgetriebe und schiefe Ebenen unter Verwendung von Stellzylinderkolbenanordnungen heb- und senkbar sein.The advantages achieved are to be seen in the fact that steel bars to be bent according to the invention can be supported with the aid of the supporting device during the bending process in such a way as is necessary to avoid annoying sagging. Of particular advantage is the fact that an adjustment to different bending tools is easily required if bends with different bending radius are to be bent onto the steel bars. For this purpose, the support device table in the bending system according to the invention is adjustable in the manner described. The steel rod holder is adjustable in the manner described in order to be adapted to different diameters of the steel rods to be bent. The steel rods to be bent can also be clamped in the steel rod holder. A particular advantage is the fact that the support device can be moved in accordance with the length of the steel bars to be bent via the bending machine which can be moved anyway. In this connection, the length-adjustable traction means can be designed and length-adjustable in various ways. A preferred embodiment is characterized in that the length-adjustable traction means can be wound onto a spool with a return spring and the unwinding length of the traction means is adjustable. It goes without saying that in the bending system according to the invention, the transfer of the steel bars to be bent from the feed conveyor to the bending machine unit must be carried out simply and quickly, as is customary in the context of a flexible production line. To this end, the invention teaches that a support conveyor is arranged for the support devices, the conveying plane of which can be raised or lowered to the level of the inlet element of the support device for the purpose of transferring the steel bars arranged side by side on the feed conveyor. For this purpose, the level of funding via lever gear and inclined planes can be raised and lowered using actuating cylinder piston arrangements.
