Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Biegen von flächigem Metallmaterial wie Baustahlmatte, in dem auf das auf einer Auflage befindliche Material nach dessen Festlegen ein Biegeelement wie Biegestab im erforderlichen Umfang einwirkt, sowie auf eine Vorrichtung insbesondere zum Durchführen des Verfahrens.The invention relates to a method for bending flat metal material such as structural steel mat, in which a bending element such as a bending rod acts to the required extent on the material on a support after it has been fixed, and to a device, in particular for carrying out the method.
Stabförmige Materialien können mit sogenannten Biegeschlitten im gewünschten Umfang gebogen werden, um Endformen gewünschter Geometrien zu erzielen. Beispielhaft sei auf die Europäische Patentanmeldung 0 238 026 verwiesen.Rod-shaped materials can be bent to the desired extent using so-called bending slides in order to achieve the final shapes of the desired geometries. Reference is made, for example, to European patent application 0 238 026.
Flächige Materialien wie z.B. Baustahlmatten zu biegen, ist recht aufwendig. So ist es erforderlich, diese auf einer mit abgewinkelten Haken versehene Auflage zu legen. Dabei werden quer verlaufende Stahlstäbe von den Haken erfaßt, um so sicherzustellen, daß das Mattenmaterial beim Biegen nicht verrutschen kann und die gewünschte Biegelinie eingehalten wird.Flat materials such as Bending structural steel mats is quite complex. So it is necessary to place it on a support provided with angled hooks. In this case, transverse steel bars are gripped by the hooks in order to ensure that the mat material cannot slip during bending and that the desired bending line is observed.
Nachteilig entsprechender Verfahren ist es, daß das Festlegen und Entfernen von den mit den Haken oder Fingern versehenenA disadvantage of corresponding methods is that the fixing and removal of those provided with the hooks or fingers
Auflagen zeit- und personalaufwendig ist. Ferner kann nicht jede beliebige Linie als Biegelinie gewählt werden. Vielmehr hängt diese vom Verlauf der Querstäbe ab.Is time-consuming and personnel-intensive. Furthermore, not every line can be selected as a bending line. Rather, it depends on the course of the cross bars.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren und eine Vorrichtung der zuvor beschriebenen Art so auszubilden, daß mit konstruktiv einfachen Mitteln das Material in jeder gewünschten Position zu dem Biegeelement festlegbar und biegbar ist, wobei weder das Befestigen noch das Entfernen des Materials zu Problemen führt.The object of the present invention is to develop a method and a device of the type described above in such a way that the material can be fixed and bent in any desired position relative to the bending element using structurally simple means, neither fixing nor removing the material causing problems .
Die Aufgabe wird erfahrungsgemäß im wesentlichen dadurch gelöst, daß das Material zwischen der Auflage und einem absenkbaren Halteelement festgeklemmt wird. Folglich ist es nicht mehr erforderlich, daß das Material mit Haken wie Fingern wechselwirkt, um ein Festlegen sicherzustellen. Vielmehr genügt es, daß das Material, sobald es in der gewünschten Position auf der Auflage liegt, von dem absenkbaren Halteelement festgehalten wird. Um das Material sodann zu entfernen, ist es nur noch erforderlich, das Halteelement zu entfernen. Dabei kann bei geschlossenen Biegeformen, also bei stirnseitig offenen Formen, das Halteelement seitlich aus diesen herausgezogen werden, so daß infolgedessen das gebogene Material selbst ohne Schwierigkeiten entfernt werden kann. Beim Drehen des Materials in bezug auf das Biegeelement wie Biegestab braucht das Halteelement nur in dem Umfang angehoben werden, daß das Material selbst bewegt bzw. gedreht werden kann.Experience has shown that the object is essentially achieved in that the material is clamped between the support and a lowerable holding element. As a result, the material no longer needs to interact with hooks like fingers to ensure setting. Rather, it is sufficient that the material, as soon as it lies in the desired position on the support, is held by the lowerable holding element. To then remove the material, it is only necessary to remove the holding element. In the case of closed bending molds, that is to say in the case of molds which are open on the end face, the holding element can be pulled out laterally of these, so that the bent material itself can consequently be removed without difficulty. When rotating the material with respect to the bending element such as a bending rod, the holding element only needs to be raised to the extent that the material itself can be moved or rotated.
Eine Vorrichtung zum Biegen von flächigem Material wie Baustahlmatte umfassend eine Auflage für das Material und zumindest ein Biegeelement wie Biegestab, das zum Biegen im erforderlichen Umfang auf das Material einwirkt, zeichnet sich dadurch aus, daß in Richtung auf die Auflage ein Halteelement zum Festklemmen des Materials absenkbar ist. Dabei kann ergänzend das Halteelement senkrecht zur Förderrichtung des Materials verschiebbar ausgebildet sein, um so ein Entfernen aus einer geschlossenen Form zu ermöglichen.A device for bending sheet material such as structural steel mat comprising a support for the material and at least one bending element such as a bending rod, which acts on the material to the extent necessary for bending, is characterized in that a holding element for clamping the material in the direction of the support is lowerable. In addition, the holding element can be designed to be displaceable perpendicular to the conveying direction of the material, in order to enable removal from a closed form.
Insbesondere zeichnet sich die Erfindung dadurch aus, daß das Halteelement in bezug auf die der Auflage zugewandten Seite flächig ausgebildet ist. Hierdurch ist ein erforderliches Festklemmen des Materials möglich, ohne daß zu große Kräfte auf dieses Einwirken müssen.In particular, the invention is characterized in that the holding element is flat in relation to the side facing the support. This enables the material to be clamped in place without excessive forces having to act on it.
Nach einer hervorzuhebenden Ausgestaltung der Erfindung dient das Halteelement seinerseits als Anschlag für Biegeelemente. Hierzu kann das Halteelement z.B. als dreikantsäulenförmiges Element ausgebildet sein, das aus einem T-Eisen mit den Steg mit den Flanschen verbindenden Stahlblechen bestehen kann. Diese Seiten dienen dann als Anschlagfläche für das Biegeelement wie Biegestab.According to an embodiment of the invention to be emphasized, the holding element in turn serves as a stop for bending elements. For this purpose, the holding element can e.g. be designed as a triangular column-shaped element, which can consist of a T-iron with the web with the flanges connecting steel sheets. These sides then serve as a stop surface for the bending element such as a bending rod.
Das Biegeelement geht seinerseits vorzugsweise von einem um eine unterhalb, vorzugsweise im Bereich der Biegelinie des Halteelementes und parallel zu dieser verlaufenden Achse verschwenkbaren Vierkantrohr aus. Das Verschwenken des Vierkantrohres selbst kann über Hydraulikzylinder erfolgen.For its part, the bending element is preferably based on a square tube which can be pivoted below, preferably in the region of the bending line of the holding element and parallel to this axis. The square tube itself can be pivoted using hydraulic cylinders.
Folglich ist mit konstruktiv einfachen Mitteln eine Biegevorrichtung gegeben, mit Hilfe derer ein einwandfreies Festlegen des zu biegenden Materials möglich ist, ohne daß es Haken oder ähnliches zum Festlegen des Materials selbst bedarf.Consequently, a structuring device is provided with structurally simple means, with the aid of which a correct fixing of the material to be bent is possible without the need for hooks or the like for fixing the material itself.
Das Halteelement selbst kann von in seinen Stirnbereichen vorhandenen Halterungen ausgehen, die ihrerseits über z.B. ein Kettenantrieb oder Hydraulikzylinder lageverschiebbar sind.The holding element itself can start from brackets present in its end regions, which in turn can be connected via e.g. a chain drive or hydraulic cylinder are displaceable.
Nach einer weiteren Ausführungsform kann zu beiden Seiten der Auflage ein Biegeelement verschwenkbar angeordnet sein, um so Biegungen im bzw. entgegen dem Uhrzeigersinn vorzunehmen.According to a further embodiment, a bending element can be arranged pivotably on both sides of the support in order to make bends clockwise or counterclockwise.
Um gleichzeitig z.B. eine U-Form mit gewünschter Steglänge zu biegen, können zwei relativ zueinander bewegbare Vorrichtungen vorgesehen sein. Dabei kann der Rahmen einer Vorrichtung so ausgebildet sein, daß dieser die andere Vorrichtung teilweise umfaßt, so daß der Abstand der Biegelinien gegebenenfalls sehr klein gewählt werden kann.In order to simultaneously bend, for example, a U-shape with the desired web length, two devices which can be moved relative to one another can be provided. The frame of one device can be designed so that the other device partially includes, so that the distance between the bending lines can optionally be selected to be very small.
Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen, den diesen zu entnehmenden Merkmalen -für sich und/oder in Kombination-, sondern auch aus der nachfolgenden Beschreibung von der Zeichnung zu entnehmenden Ausführungsbeispielen.Further details, advantages and features of the invention emerge not only from the claims, the features to be extracted from them - by themselves and / or in combination - but also from the following description of exemplary embodiments to be taken from the drawing.

In Fig. 1 ist eine Vorrichtung (10) zum Biegen von stabförmigem Material wie Baustahlmatten dargestellt. Die Vorrichtung umfaßt eine Auflage (12), ein Halteelement (14) sowie ein Biegeelement (16) als wesentliche Bestandteile. Vor und hinter der Auflage (12), die im Ausführungsbeispiel als Basisteil ein Vierkantrohr (18) umfaßt, sind nicht dargestellte Rollenbahnen angeordnet, entlang der das flächige Material verschoben wird, um in dem Bereich zwischen Auflage (12) und Halteelement (14) eingeführt bzw. aus diesem entfernt zu werden.In Fig. 1, a device (10) for bending rod-shaped material such as steel mesh is shown. The device comprises a support (12), a holding element (14) and a bending element (16) as essential components. In front of and behind the support (12), which in the exemplary embodiment comprises a square tube (18) as the base part, roller tracks (not shown) are arranged, along which the flat material is displaced in order to be introduced into the area between the support (12) and the holding element (14) or to be removed from it.
Das Halteelement (14) besteht im Ausführungsbeispiel aus einer Dreikantsäule, die aus einem T-Eisen (20) mit schräg verlaufenden Flacheisen (22) und (24) aufgebaut ist. Die Basiskanten werden durch Rundeisen (26) und (28) gebildet. Die Basiskanten (26) und (28) dienen gleichzeitig als Biegelinien für das Material. Ferner wirkt die Schrägfläche (22) als anschlag für das Biegeelement (16).In the exemplary embodiment, the holding element (14) consists of a triangular column which is constructed from a T-bar (20) with obliquely extending flat bars (22) and (24). The base edges are formed by round bars (26) and (28). The base edges (26) and (28) also serve as bending lines for the material. Furthermore, the inclined surface (22) acts as a stop for the bending element (16).
Das Halteelement (14) wird seinerseits von einer Halterung (30) aufgenommen, die entlang von Säulenelementen (32) mittels Hydraulikzylinder (34) oder Ketten (36) bzw. (38) anhebbar bzw. absenkbar ist. Letzteres erfolgt dann, wenn auf der Auflage (12) ein zu biegendes Material zum Liegen kommt und gegen ein unkontrolliertes Verrücken festzuhalten ist. Mittels der Vorrichtung erfolgt dabei ein flächiges Festklemmen.The holding element (14) is in turn received by a holder (30) which can be raised or lowered along column elements (32) by means of hydraulic cylinders (34) or chains (36) or (38). The latter occurs when a material to be bent comes to rest on the support (12) and is to be held against uncontrolled movement. Flat clamping is achieved by means of the device.
Das Halteelement (14) kann senkrecht zur Zeichenebene) verschoben werden, also relativ zu der Halterung (30) bewegt werden, nämlich dann, wenn das Material zu einer geschlossenen Form gebogen ist, um also das Halteelement aus der Form herauszuziehen und das gebogene Material entfernen zu können.The holding element (14) can be displaced perpendicular to the plane of the drawing), that is to say it can be moved relative to the holder (30), namely when the material is bent into a closed form, in order to pull the holding element out of the form and remove the bent material to be able to.
Um das von dem Halteelement (14) auf der Auflage (12) festgeklemmte Material biegen zu können, geht von einem Vierkantrohr (40) das Biegeelement (16) in Form eines Biegestabes aus. Das Vierkantrohr (40) ist um eine parallel zur Längsrichtung des Halteelementes (14) verlaufende Achse (42) verschwenkbar, die unterhalb der durch das Rundeisen (26) vorgegebenen Biegelinie verläuft. Die Drehachse (42) geht von der Auflage (12), im Ausführungsbeispiel vor dem Vierkantrohr (18) aus. Das Verschwenken des Vierkantrohres (40) und damit des Biegeelementes (16) erfolgt über Hydraulikzylinder (44).In order to be able to bend the material clamped by the holding element (14) on the support (12), the bending element (16) in the form of a bending rod starts from a square tube (40). The square tube (40) can be pivoted about an axis (42) which runs parallel to the longitudinal direction of the holding element (14) and runs below the bending line specified by the round bar (26). The axis of rotation (42) is based on the support (12), in the exemplary embodiment in front of the square tube (18). The pivoting of the square tube (40) and thus the bending element (16) takes place via hydraulic cylinders (44).
Der Hydraulikzylinder (44) geht von einem die Vorrichtung (10) aufnehmenden wagen (46) aus, der entlang einer Schiene (48) verschiebbar ausgebildet ist, um so die Vorrichtung relativ zu dem zu biegenden Material verschieben zu können.The hydraulic cylinder (44) starts from a carriage (46) which receives the device (10) and which is designed to be displaceable along a rail (48) in order to be able to move the device relative to the material to be bent.
Das Ausführungsbeispiel nach Fig. 2 zeigt ein Halteelement oder Biegestempel (48), das erwähntermaßen über Kettenelemente (36) und (38) anhebbar bzw. absenkbar ist. Weitere Elemente der Vorrichtung gemäß Fig. 1 sind in Fig. 2 aus Übersichtlichkeitsgründen nicht dargestellt. Erkennbar ist jedoch, daß das Halteelement (48) ebenfalls eine Dreikantform aufweist, wobei die Basiskanten die Biegelinien vorgeben. Auch kann das Halteelement (48) die die Ketten (36) und (38) führend aufnehmenden Säulen (50) und (52) durchsetzen, nämlich dann, wenn das Halteelement (48) von einer geschlossenen Form gebogenen Materials umgeben ist.The exemplary embodiment according to FIG. 2 shows a holding element or bending punch (48) which, as mentioned, can be raised or lowered via chain elements (36) and (38). 1 are not shown in FIG. 2 for reasons of clarity. However, it can be seen that the holding element (48) also has a triangular shape, the base edges specifying the bending lines. The holding element (48) can also receive the pillars guiding the chains (36) and (38) Enforce (50) and (52), namely when the holding element (48) is surrounded by a closed shape of curved material.
Der Fig. 3 sind weitere rein schematisch dargestellte Merkmale der erfindungsgemäßen Vorrichtung zu entnehmen. So besteht die Vorrichtung aus zwei Biegevorrichtungen (54) und (56), die den Aufbau der Biegevorrichtung (10) aufweisen können. Folglich umfaßt jede Biegevorrichtung (54) bzw. (56) eine Auflagefläche (58) bzw. (60), der jeweils ein nicht dargestelltes Halteelement zugeordnet ist, um das flächige Material wie eine Baustahlmatte (62) dann festzuklemmen, wenn die Biegeposition eingenommen ist. Ferner erkennt man, daß zu beiden Seiten der Auflagefläche ein Biegeelement (64) und (66) bzw. (68) und (70) angeordnet ist, wobei der Aufbau und das Verschwenken entsprechend dem Biegeelement (16) und der in diesem Zusammenhang beschriebenen Elemente erfolgt. Um gleichzeitig das Material (62) z.B. zu einem U formen zu können, wobei die Biegelinien einen gewünschten Abstand zueinander einnehmen sollen, ist vorgesehen, daß die Vorrichtung (56) entsprechend der Pfeildarstellung (72) zu der Vorrichtung (54) verschiebbar ist. So können verschiedene Stellungen eingenommen werden, die durch die gestrichelte Darstellung mit angedeutet werden soll. In der gewünschten Biegeposition kann sodann das Material (62) gleichzeitig um die Biegelinie (74) und um die Biegelinie (76) bzw. (76′) gebogen werden, nämlich dann, wenn das Biegeelement (64) bzw. (70) in Richtung auf das Material (62), also aus der Zeichenebene heraus, verschwenkt wird.3 shows further purely schematically illustrated features of the device according to the invention. The device consists of two bending devices (54) and (56), which can have the structure of the bending device (10). Consequently, each bending device (54) or (56) comprises a support surface (58) or (60), each of which is assigned a holding element, not shown, in order to clamp the flat material like a structural steel mat (62) when the bending position has been assumed . Furthermore, it can be seen that a bending element (64) and (66) or (68) and (70) is arranged on both sides of the bearing surface, the structure and pivoting corresponding to the bending element (16) and the elements described in this connection he follows. To simultaneously remove the material (62) e.g. To be able to form a U, the bending lines being to be at a desired distance from one another, it is provided that the device (56) can be displaced relative to the device (54) in accordance with the arrow representation (72). In this way, various positions can be assumed, which are also indicated by the dashed line. In the desired bending position, the material (62) can then be bent simultaneously around the bending line (74) and around the bending line (76) or (76 '), namely when the bending element (64) or (70) in the direction is pivoted onto the material (62), i.e. out of the drawing plane.
Wie die Fig. 3 des weiteren erkennen läßt, können die Biegevorrichtungen (54) und (56) recht dicht zusammengefahren werden. Ursächlich hierfür ist, daß der Halte- und Fahrrahmen der Biegevorrichtung (56) die Biegevorrichtung (54) seitlich umfaßt, so daß entsprechend der gestrichelten Darstellung nur ein geringer Abstand zwischen den Biegelinien (74) und (76′) einstellbar ist.As can also be seen in FIG. 3, the bending devices (54) and (56) can be moved together very closely. The reason for this is that the holding and traveling frame of the bending device (56) laterally surrounds the bending device (54), so that only a small distance between the bending lines (74) and (76 ') can be set in accordance with the broken line.
