Description

Die Erfindung betrifft eine Vorrichtung zum Biegen von stabförmigem Material zu Betonbewehrungselementen, mit einem Gestell zum Abstützen einer Materialvor­schubeinrichtung und einem am Gestell um die Vorschubachse drehbar gelagerten, relativ zum Gestell einstellbaren Träger für Biegeorgane.The invention relates to a device for bending rod-shaped material into concrete reinforcement elements, having a frame for supporting a material feed device and a support for bending members which is rotatably mounted on the frame about the feed axis and is adjustable relative to the frame.

Bei einer aus der US-PS 4,782.684 bekannten Vorrich­tung dieser Art weist der Träger für die Biegeorgane eine angetriebene Drehscheibe auf, die am Gestell um die Vorschubachse in beiden Richtungen drehbar gelagert und mit einer Durchtrittsöffnung für das stabförmige Material versehen ist. Von der Drehscheibe erstreckt sich ein Arm weg, der mit einer mit der Drehscheibenöffnung fluchtenden Geradführung versehen ist, die vom Material durchsetzt wird. Der Träger trägt an seinem freien Ende einen Biegekopf, der mit Biegedornen ausgestattet ist, die um eine zur Führung senkrechte Achse drehbar bzw. verschwenk­bar sind. Die bekannte Ausführung hat vor allem den Nachteil, daß Bügel mit größeren Schenkellängen vom Trägerarm nicht wirksam abgestützt werden können und Gefahr laufen, sich unter dem Eigengewicht zu verformen. Ander­seits ist mangels ausreichender Abstützung keine Möglich­keit gegeben, einer Auffederungstendenz des Materials beim Biegen entgegenzuwirken bzw. diese zu kompensieren. Bei der bekannten Konstruktion ist schließlich eine vom Biegekopf entfernt auf einem gesonderten Gestell angeordnete Abtrenn­einrichtung für das gebogene Element vorgesehen, die konstruktiv kompliziert und störungsanfällig ist.In a device of this type known from US Pat. No. 4,782,684, the support for the bending members has a driven turntable which is rotatably mounted on the frame in both directions about the feed axis and is provided with a passage opening for the rod-shaped material. An arm extends away from the turntable and is provided with a straight guide aligned with the turntable opening, through which the material passes. The carrier has at its free end a bending head which is equipped with bending mandrels which can be rotated or pivoted about an axis perpendicular to the guide. The known design has the particular disadvantage that brackets with larger leg lengths cannot be effectively supported by the support arm and run the risk of deforming under their own weight. On the other hand, due to a lack of sufficient support, there is no possibility of counteracting or compensating for a tendency of the material to spring open during bending. Finally, in the known construction, a separating device for the bent element, which is arranged on a separate frame from the bending head, is provided, which is structurally complicated and prone to failure.

Die Aufgabe der Erfindung besteht darin, die ge­schilderten Nachteile zu vermeiden und eine Vorrichtung der einleitend angegebenen Art zu schaffen, die es ermöglicht, stabförmiges Material in verschiedenen Biegeebenen und mit beliebigen Schenkellängen einwandfrei zu biegen sowie die gebogenen Elemente auf einfache Weise abzutrennen. Die Erfindung soll zugleich das kontinuierliche Biegen von räumlichen Bewehrungen und sogenannten Bügelkörben ermög­lichen. Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, daß der Träger als in vorbestimmter Winkellage relativ zum Gestell einstellbarer Material-Auflagetisch ausgebildet ist, auf welchem eine den Biegeorganen in Materialvorschubrichtung vorgeschaltete Schneideinrichtung zum Abtrennen des stabförmigen Materials vom Materialstrang nach dem Biegevorgang vorgesehen ist.The object of the invention is to avoid the disadvantages described and to provide a device of the type mentioned in the introduction, which makes it possible to bend rod-shaped material properly in various bending planes and with any leg lengths and to separate the bent elements in a simple manner. The invention is also intended to continuously bend allow spatial reinforcement and so-called bow baskets. The device according to the invention is characterized in that the carrier is designed as a material support table that can be adjusted in a predetermined angular position relative to the frame, on which a cutting device upstream of the bending elements in the material feed direction is provided for separating the rod-shaped material from the material strand after the bending process.

Durch die Erfindung wird vorteilhaft eine einstellbare Auflagefläche für die gebogenen Bewehrungselemente ge­schaffen, die eine einwandfreie Formung der Elemente ohne Deformationsgefähr gewährleistet, wobei die Elemente ohne großen konstruktiven Aufwand und ohne Zeitverzögerung sicher abgetrennt werden können.The invention advantageously creates an adjustable support surface for the curved reinforcement elements, which ensures a perfect shaping of the elements without risk of deformation, the elements being able to be safely separated without great design effort and without any time delay.

Gemäß einem bevorzugten Ausführungsbeispiel der Erfin­dung ist auf dem Auflagetisch mit Abstand von den Biegeorganen eine Leiste zur elektrischen Kontaktgabe mit dem gebogenen Material vorgesehen, über welche die Drehbe­wegung des Tisches steuerbar ist. Hiedurch wird bei einem unbeabsichtigten Abheben des gebogenen Elementes vom Auflagetisch ein Nachstellen des Auflagetisches in erneute Anlage an das Element erreicht.According to a preferred embodiment of the invention, a bar for electrical contact with the bent material is provided on the support table at a distance from the bending members, via which the rotary movement of the table can be controlled. In this way, if the curved element is inadvertently lifted off the support table, the support table is readjusted in a new contact with the element.

Nach einem weiteren Merkmal der Erfindung ist unter­halb des Auflagetisches eine Aufnahme für in der Hori­zontallage des Auflagetisches nach unten fallende Beweh­rungselemente vorgesehen, wobei die Aufnahme vorzugsweise drehbar ist.According to a further feature of the invention, a receptacle is provided below the support table for reinforcement elements falling downward in the horizontal position of the support table, the receptacle preferably being rotatable.

Vorzugsweise ist ferner die Drehlagerung des Auflage­tisches als zur Vorschubachse koaxiale Rohrführung für das stabförmige Material ausgebildet.Furthermore, the rotary bearing of the support table is preferably designed as a pipe guide coaxial to the feed axis for the rod-shaped material.

Die Erfindung wird nachfolgend an einem Ausführungs­beispiel unter Bezugnahme auf die Zeichnungen näher erläutert, in denen zeigen:

  • Fig. 1 eine schematische Perspektivansicht einer Biegevorrichtung gemäß der Erfindung, und die
  • Fig. 2a - 2c die erfindungsgemäße Biegevorrichtung mit unterschiedlichen Anordnungen des die Biegeebene definie­ renden Auflagetisches relativ zur Materialvorschubebene.
The invention is explained in more detail below using an exemplary embodiment with reference to the drawings, in which:
  • Fig. 1 is a schematic perspective view of a bending device according to the invention, and the
  • 2a-2c the bending device according to the invention with different arrangements of the bending plane renden support table relative to the material feed plane.

Gemäß Fig. 1 wird der Biegevorrichtung zu biegendes Stabmaterial in Richtung des Pfeiles P1 von einem nicht dargestellten Materialvorrat über eine ebenfalls nicht dargestellte Richteinrichtung zugeführt und entlang einer Vorschubachse X-X weitergeleitet.According to FIG. 1, the rod material to be bent is fed in the direction of arrow P1 from a material supply, not shown, via a straightening device, also not shown, and is passed along a feed axis X-X.

Die Biegevorrichtung besteht im wesentlichen aus zwei Teilen 1 und 2, wobei Teil 1 ortsfest angeordnet und Teil 2 um eine mit der Vorschubachse X-X zusammenfallende Dreh­achse entsprechend dem Doppelpfeil P₂ drehbar mit dem Teil 1 verbunden ist. Der Teil 1 besteht aus einem ortsfesten Gestell 3, das einen Vorschubrollensatz 4, einen zusätz­lichen, dem Vorschubrollensatz 4 nachgeschalteten Richt­rollensatz 5 zum Ausgleich etwaiger Verformungen des Stabmaterials durch die Vorschubrollen sowie einen Drehan­trieb 6 für den mittels einer Lagerung 7 am Teil 1 drehbar befestigten Teil 2 trägt.The bending device consists essentially of two parts 1 and 2, part 1 being arranged stationary and part 2 being rotatably connected to part 1 about an axis of rotation coinciding with the feed axis X-X in accordance with the double arrow P₂. Part 1 consists of a stationary frame 3 which has a feed roller set 4, an additional straightening roller set 5 connected downstream of the feed roller set 4 to compensate for any deformation of the rod material by the feed rollers, and a rotary drive 6 for the part 2 rotatably fastened to part 1 by means of a bearing 7 wearing.

Der Teil 2 besteht im wesentlichen aus einem Auflage­tisch 10, der eine Schneideinrichtung 8 und einen Biegekopf 9 trägt.The part 2 consists essentially of a support table 10 which carries a cutting device 8 and a bending head 9.

Im Vorschubrollensatz 4 ist zweckmäßig ein Meßrad 11 integriert, über welches die Länge des durchlaufenden Stabmaterials erfaßt und die Schneideinrichtung 8 nach Erreichen der vorbestimmten Länge des zu biegenden Materials angesteuert wird, um damit den fertigen Bügel vom Materialstrang abzutrennen. Es ist außerdem im Rahmen der Erfindung möglich, ein mit einer entsprechenden Gegenrolle versehenes Meßrad direkt vor der Schneideinrichtung 8 auf dem Auflagetisch 10 anzuordnen.In the feed roller set 4, a measuring wheel 11 is expediently integrated, by means of which the length of the rod material passing through is detected and the cutting device 8 is actuated after reaching the predetermined length of the material to be bent, in order to thereby separate the finished bow from the material strand. It is also possible within the scope of the invention to arrange a measuring wheel provided with a corresponding counter roller directly in front of the cutting device 8 on the support table 10.

Um Verschmutzungen zu vermeiden, sind der Vorschub­rollensatz 4 und der Richtrollensatz 5 mit einer zu Servicezwecken abnehmbaren Abdeckhaube 12 abgedeckt.In order to avoid contamination, the feed roller set 4 and the straightening roller set 5 are covered with a cover 12 which can be removed for service purposes.

Der Drehantrieb 6 für den Auflagetisch 10 ist in bekannter Weise ausgebildet. Nur beispielsweise ist schema­tisch eine Antriebsschnecke 6′ angedeutet. Die Lagerung 7 des Auflagetisches 10 ist mit einer Längsbohrung 13 koaxial zur Vorschubachse X-X versehen, um den ungehinderten Durchlauf des zu biegenden Stabmaterials vom Richtrollen­ satz 5 zum Biegekopf 9 zu ermöglichen.The rotary drive 6 for the support table 10 is designed in a known manner. Only for example, a drive screw 6 'is indicated schematically. The bearing 7 of the support table 10 is provided with a longitudinal bore 13 coaxial to the feed axis XX in order to allow the rod material to be bent to pass freely from the straightening rolls to allow set 5 to the bending head 9.

Die Schneideinrichtung 8 ist ebenfalls in bekannter Weise ausgebildet und befindet sich unmittelbar vor dem Biegekopf 9, um auch extrem kurze Endschenkel der Bügel herstellen zu können. Durch die Anordnung der Schneidein­richtung 8 auf dem drehbaren Auflagetisch 10 und in der Vorschubachse X-X kann die Schneideinrichtung 8 ohne zusätzlichen Positionieraufwand den fertigen Bügel vom Materialstrang rasch abtrennen.The cutting device 8 is also designed in a known manner and is located directly in front of the bending head 9 in order to be able to produce extremely short end legs of the stirrups. By arranging the cutting device 8 on the rotatable support table 10 and in the feed axis X-X, the cutting device 8 can quickly separate the finished bracket from the material strand without additional positioning effort.

Der Biegekopf 9 weist einen in einer Führung 9′ bewegbaren Biegekopfteller 14 auf, auf dem ein feststehen­der Biegedorn 15 und ein zum Biegen des Stabes schwenkbarer Biegebolzen 16 angeordnet sind. Im Rahmen der Erfindung können auch anders ausgebildete Biegewerkzeuge Verwendung finden.The bending head 9 has a in a guide 9 'movable bending head plate 14 on which a fixed mandrel 15 and a pivot pin 16 for bending the rod are arranged. In the context of the invention, differently designed bending tools can also be used.

Der Auflagetisch 10 hat eine Tischfläche 10′, die zumindest so groß wie die vom Umriß der herzustellenden Bügel begrenzte Fläche ist und die Biegeebene definiert. In allen Positionen des Auflagetisches 10 mit nach oben weisender Tischfläche 10′ stützt der Auflagetisch die Bügel während des Biegevorganges ab. Bei besonders großen Bügeln bildet der Auflagetisch 10 gemeinsam mit dem Gestell 3 eine Abstützung für die Bügel. Auf dem Auflagetisch 10 ist außerdem mit Abstand vom Biegekopf eine nur schematisch dargestellte, zweiteilige Kontaktleiste 17 angeordnet, welche bei elektrischer Kontaktgabe mit dem herzustellenden Element die Drehbewegung des Auflagetisches 10 und damit die Lage der Biegeebene im Raum steuert, u.zw. auch während des Biegens, um beispielsweise bei Auswandern des Elementes aus der Biegeebene die Tischfläche 10′ des Auflagetisches 10 in erneute Anlage an das Element nachzustellen und damit die Herstellung flacher Bügel zu gewährleisten.The support table 10 has a table surface 10 ', which is at least as large as the area delimited by the outline of the bracket to be manufactured and defines the bending plane. In all positions of the support table 10 with the table surface 10 facing upwards, the support table supports the brackets during the bending process. In the case of particularly large stirrups, the support table 10 forms a support for the stirrups together with the frame 3. On the support table 10, a two-part contact strip 17, which is only shown schematically, is also arranged at a distance from the bending head, which controls the rotary movement of the support table 10 and thus the position of the bending plane in space when electrically making contact with the element to be produced, etc. also during bending, for example, when the element emigrates from the bending plane, to adjust the table surface 10 'of the support table 10 in renewed contact with the element and thus to ensure the production of flat brackets.

In den Fig. 2a - 2c sind verschiedene Relativlagen des Auflagetisches 10 und damit der Biegeebene gegenüber der Vorschubebene dargestellt, die durch die Anordnung des Vorschubrollensatzes 4 und des Richtrollensatzes 5 mit dem ortsfesten Gestell 3 definiert und unveränderbar ist. Die in Fig. 1 dargestellte Biegemaschine zeigt eine Überein­ stimmung von Biegeebene und Vorschubebene, die als Grund­einstellung anzusehen ist.2a-2c show different relative positions of the support table 10 and thus the bending plane with respect to the feed plane, which is defined and unchangeable by the arrangement of the feed roller set 4 and the straightening roller set 5 with the stationary frame 3. The bending machine shown in Fig. 1 shows an agreement adjustment of bending level and feed level, which is to be regarded as the basic setting.

In Fig. 2a ist nur eine kleine Abweichung zwischen der Biegeebene und der Vorschubebene gezeigt, die z.B. bei der Herstellung von verschränkten Bügeln infolge der schräg­stehenden Tischfläche ein bewußtes Überkompensieren bei der Biegung und eine Gegenverformung des Stabmaterials bewirkt und damit ein unerwünschtes Auseinanderklaffen der Bügel­schenkel im fertigen Bügel verhindert.In Fig. 2a only a small deviation between the bending plane and the feed plane is shown, which e.g. in the production of entangled temples due to the inclined table surface, a deliberate overcompensation in the bending and a counter-deformation of the rod material causes and thus prevents an undesirable gaping of the temple legs in the finished temple.

In Fig. 2c ist der Auflagetisch 10 soweit aus der Grundstellung gemäß Fig. 1 herausgedreht, daß der Auflage­tisch 10 nahezu horizontal mit nach unten weisender Tischfläche angeordnet ist. Da in dieser Lage die Biege­werkzeuge 15, 16 nach unten weisen, ist es möglich, beispielsweise Bügel B ohne zusätzliche Auffangeinrichtung in vertikaler Richtung P₃ auf eine beispielsweise als Drehteller ausgebildete Ablageeinrichtung 18 fallen zu lassen. Der Drehteller 18 ist entsprechend dem Doppelpfeil P₄ drehbar, um ein geordnetes Abstapeln der Bügel B zu ermöglichen.In FIG. 2c, the support table 10 is rotated out of the basic position according to FIG. 1 to such an extent that the support table 10 is arranged almost horizontally with the table surface facing downward. Since in this position the bending tools 15, 16 point downwards, it is possible, for example, to drop bracket B without an additional collecting device in the vertical direction P 3 onto a storage device 18, for example a rotary plate. The turntable 18 is rotatable according to the double arrow P₄ to allow an orderly stacking of the bracket B.

In der in Fig. 2c dargestellten Lage des Auflage­tisches 10 ist es außerdem möglich, in einem kontinuier­lichen Arbeitsprozeß räumliche Bewehrungen und Bügelkörbe herzustellen. Auch in diesem Fall ist es zweckmäßig, den Drehteller 18 in seiner Drehbewegung entsprechend dem Doppelpfeil P₄ auf den Biegevorgang abzustimmen.In the position of the support table 10 shown in FIG. 2c, it is also possible to produce spatial reinforcements and bow baskets in a continuous working process. In this case, too, it is expedient to adjust the rotary plate 18 in its rotational movement in accordance with the double arrow P₄ to the bending process.

Es versteht sich, daß die Erfindung nicht auf die dargestellten Ausführungsbeispiele beschränkt ist, diese können vielmehr im Rahmen des allgemeinen Erfindungsge­dankens verschiedentlich abgewandelt werden.It goes without saying that the invention is not restricted to the exemplary embodiments shown, but rather they can be modified in various ways within the scope of the general inventive concept.
