Abstract
Ce procede sert au cintrage des toles ayant un profil continu dans une direction, par exemple des toles avec un profil trapezoidal ou rectangulaire. Pour obtenir un cintrage economique de toles semblables sans diminuer leur resistance, des bords longitudinaux (5) continus sont formes dans la tole (1) pendant le cintrage au moins dans le secteur des deformations sous pression se produisant par le cintrage, c'est-a-dire dans le domaine de la contrainte de compression; le cas echeant, ce sont des bords existants renforces. Pour la mise en oeuvre du procede, un dispositif peut etre utilise; ce dispositif est compose d'une paire de cylindres (6 + 7) en mouvement, d'un cylindre fixe (6) et d'un cylindre reglable (7) ainsi que d'au moins un cylindre de cintrage reglable (8, eventuellement 9), dispose eventuellement derriere la paire de cylindres (6 + 7). L'ensemble des cylindres (6, 7, 8, 9) presente un profil, qui correspond au profil de la tole, et au moins les cylindres (6, 7) de la paire sont profiles conformement aux bords longitudinaux formes dans la tole (1).This method is used for bending sheets having a continuous profile in one direction, for example sheets with a trapezoidal or rectangular profile. To obtain an economic bending of similar sheets without reducing their resistance, continuous longitudinal edges (5) are formed in the sheet (1) during bending at least in the sector of deformations under pressure occurring by bending, that is to say ie in the field of compressive stress; if necessary, these are reinforced edges. For the implementation of the method, a device can be used; this device is composed of a pair of moving cylinders (6 + 7), a fixed cylinder (6) and an adjustable cylinder (7) as well as at least one adjustable bending cylinder (8, possibly 9), possibly arranged behind the pair of cylinders (6 + 7). The set of cylinders (6, 7, 8, 9) has a profile, which corresponds to the profile of the sheet, and at least the cylinders (6, 7) of the pair are profiled in accordance with the longitudinal edges formed in the sheet ( 1).
Description
Verfahren zum Biegen von Blechen und Vorrichtung zur Durchführung des VerfahrensProcess for bending sheet metal and device for carrying out the process
Die Erfindung bezieht sich auf ein Verfahren zum Biegen von Blechen mit in einer Richtung durchlaufenden Profil- form, z.B. von Blechen mit trapezrechteck- oder dreieck- för iger Profilierung.The invention relates to a method for bending sheet metal with a continuous profile shape, e.g. of sheets with trapezoidal or triangular profiles.
Bleche mit Profilierung, insbesondere sogenannte Trapez¬ bleche, können um senkrecht zur Profilierung verlaufende Achsen kaum oder nur mit großem Aufwand, gebogen werden. Der Grund hiefü'r liegt darin, daß beim Biegen Zug- und Druckspannungen auftreten, die verwendeten Bleche jedoch wohl Zugspannungen, nicht jedoch Druckspannungen auf¬ nehmen können. Versucht man z.B. ein Trapezblech auf übliche Weise zu biegen, so kommt es im Druckspannungs- bereich zu Ausbeulungen, deren Ausmaß erst ab einemSheets with profiling, in particular so-called trapezoidal sheets, can hardly be bent, or only with great effort, around axes perpendicular to the profiling. The reason hiefü 'r is that occur during bending tensile and compressive stresses, the sheets used, however, can take compressive stresses auf¬ probably tensile stresses is not. If, for example, you try to bend a trapezoidal sheet in the usual way, bulges occur in the compressive stress area, the extent of which only starts from one
Biegeradius von etwa 25 m in erträglichen Grenzen liegt.Bending radius of about 25 m is within tolerable limits.
Es besteht jedoch ein großer Bedarf nach gebogenen Blechen mit Biegeradien, die wesentlich kleiner als 25 m sind, z.B. für Dachkonstruktionen, wo Biegeradien von 5 bis 10 und auch darunter erwünscht sind.However, there is a great need for curved sheets with bending radii that are significantly smaller than 25 m, e.g. for roof constructions where bending radii from 5 to 10 and below are required.
Es ist ein Verfahren zum Biegen von Trapezblechen bekannt geworden, bei welchem auf einer Presse in Abstand vonein¬ ander und quer zur Profilierung verlaufende Vertiefungen in das Blech geprägt werden. Auf diese Weise läßt sich zwar das Trapezblech tatsächlich biegen, doch haften dem Ver¬ fahren schwerwiegende Nachteile an. Einerseits ist das Ver¬ fahren sehr langsam und kostspielig, da es schrittweise und nicht kontinuierlich arbeitet. Andererseits ist das nach dem bekannten Verfahren hergestellte Blech kaum be- lastbar, da es wegen der querverlaufenden Vertiefungen leicht nach Art eines Ziehharmonikabalges zusammenklappt.
Es ist ein Ziel der Erfindung, ein Verfahren zum Biegen von Blechen mit Profilierung, insbesondere von Trapez¬ blechen zu schaffen, das bei rascher, und einfacher Arbeitsweise gebogene~Bl eche hoher Qualität ergibt. Vor allem sollen die Bleche durch das Biegen nicht an Festig¬ keit verlieren.A method for bending trapezoidal sheets has become known, in which depressions running at a distance from one another and transverse to the profile are embossed into the sheet. Although the trapezoidal sheet can actually be bent in this way, the method has serious disadvantages. On the one hand, the process is very slow and expensive because it works step by step and not continuously. On the other hand, the sheet metal produced by the known method can hardly be loaded because it easily collapses in the manner of an accordion bellows because of the transverse depressions. It is an object of the invention to provide a method for bending sheet metal with profiling, in particular trapezoidal sheet metal, which results in high quality curved sheets with a quick and simple method of operation. Above all, the sheets should not lose strength as a result of bending.
Dieses Ziel läßt sich mit einem Verfahren der eingangs genannten Art erreichen, bei welchem erfindungsgemäß in dem Blech während des Biegens zumindest im Bereich der beim Biegen auftretenden Material Stauchungen, d.h. im Druckspannungsbereich, durchgehende Längssicken ausge¬ bildet bzw. bereits vorhandene Sicken verstärkt werden.This goal can be achieved with a method of the type mentioned in the introduction, in which, according to the invention, compressions in the sheet during bending, at least in the region of the material occurring during bending, i.e. in the compressive stress area, continuous longitudinal beads are formed or existing beads are reinforced.
Auf diese Weise lassen sich Bleche mit Profilierung überraschend einfach und mit hoher Geschwindigkeit biegen. Die Bleche weisen außerdem nach dem Biegen zumindest die gleiche Festigkeit wie vorher auf.In this way, profiled sheets can be bent surprisingly easily and at high speed. After bending, the sheets also have at least the same strength as before.
Es ist an dieser Stelle anzumerken, daß ebene, somit nich gebogene Trapezbleche mit Längssicken dem Stand der Techni angehören. Derartige Längssicken in den Innen- und Außen¬ gurten dienen der Erhöhung des Trägheits- und des Wider¬ standsmomentes. Mit dem Verfahren nach der Erfindung können auch Bleche mit bereits vorhandenen Sicken gebogen werden, entweder durch Nacharbeiten dieser Sicken oder durch Herstellung neuer, zusätzlicher Sicken.It should be noted at this point that flat, therefore non-curved trapezoidal sheets with longitudinal beads belong to the state of the art. Such longitudinal beads in the inner and outer belts serve to increase the moment of inertia and resistance. The method according to the invention can also be used to bend metal sheets with existing beads, either by reworking these beads or by producing new, additional beads.
Will man Bleche mit trapezförmiger Profilierung, die - in Bezug auf die Krümmungsachse - Innen-- und Außengurte mit dazwischenliegenden Stegen aufweisen, biegen, so ist es zweckmäßig, wenn zumindest in den Innengurten und in den Stegen wenigstens eine Sicke ausgebildet wird. Da die Druckspannungen während des Biegens bloß in den Innen¬ gurten bzw. in den innenliegenden Stegteilen auftreten, genügt es, in diesen Bereichen Sicken auszubilden.
Oft ist es jedoch aus fertigungstechnischen und wirt- schaftlichen Gründen zweckmäßig, wenn in. der Mitte der Außen- und Innengurte sowie im Bereich der. Blechmitten¬ ebene in den Stegen jeweils eine Sicke ausgebildet wird.If you want to bend sheets with a trapezoidal profile, which - in relation to the axis of curvature - have inner and outer belts with webs in between, it is advisable if at least one bead is formed in the inner belts and in the webs. Since the compressive stresses only occur in the inner belts or in the inner web parts during bending, it is sufficient to form beads in these areas. However, it is often expedient for manufacturing and economic reasons if in the middle of the outer and inner belts as well as in the area of the. A central bead is formed in each of the webs in the webs.
Zur Durchführung des erfindungsgemäßen Verfahrens eignet sich besonders eine Vorrichtung mit einem angetriebenen Walzenpaar, das eine ortsfeste sowie eine zustellbare Walze aufweist, sowie mit zumindest einer, vor bzw. hinter dem Walzenpaar angeordneten, zustellbaren Biege¬ walze bei welcher sämtliche Walzen ein Profil aufweisen, das dem Blechprofil entspricht und zumindest die Walzen des Walzenpaares entsprechend den in dem Blech auszu¬ bildenden Längssicken profiliert sind.A device with a driven pair of rollers, which has a stationary and an deliverable roller, and with at least one deliverable bending roller arranged in front of or behind the pair of rollers, in which all the rollers have a profile, are particularly suitable for carrying out the method according to the invention corresponds to the sheet profile and at least the rolls of the pair of rolls are profiled in accordance with the longitudinal beads to be formed in the sheet.
Die Erfindung samt ihren weiteren Vorteilen und Merkmalen ist im folgenden an Hand beispielsweiser Ausführungen näher beschrieben, die in der Zeichnung veranschaulicht sind. Es zeigen Fig. la und b einen Schnitt durch ein Trapezblech vor bzw. nach dem Biegen, Fig. 2 und 3 in schematischer Seitenansicht eine Vorrichtung zur.

La and b show a section through a trapezoidal sheet before or after bending, Fig. 2 and 3 in a schematic side view of a device for.

Stauchungen und Verwerfungen des Bleches zur Folge haben.OMPI Result in upsetting and warping of the sheet.
Um diese Stauchungen zu vermeiden, werden beim erfindungs- 5 gemäßen Verfahren in dem Blech während des Biegens durch¬ gehende Längssicken 5 ausgebildet, die im Bereich der auf¬ tretenden Druckspannungen liegen und in Fig. 1b ange¬ deutet sind. Durch die gleichzeitig mit dem Biegen. vorge¬ nommene Ausbildung der Sicken werden die Stauchungen von den Sicken aufgenommen, sodaß.das Blech im gebogenen Zu¬ stand ohne Verwölbungen od. dgl. vorliegt, ein tadelloses Aussehen aufweist und auch in Hinblick auf seine Festig¬ keit gewonnen hat.In order to avoid these upsets, in the method according to the invention 5 continuous beads 5 are formed in the sheet during bending, which lie in the area of the compressive stresses which occur and are indicated in FIG. 1b. By simultaneously with the bending. the beadings are accommodated by the beads, so that the sheet is in the bent state without warping or the like, has an impeccable appearance and has also gained in terms of its strength.
Zum Biegen profilierter Bleche nach dem erfindungsge- mäßen Verfahren eignet sich eine Rollenprofiliermaschine, die z.B. gemäß Fig. 2 bzw. 3 aus einem Walzenpaar 5,7 besteht, dem eine erste Biegewalze 8 vorangestellt und eine zweite Biegewalze 9 nachgeordnet ist. Sämtliche Walzen sind als Profilwalzen ausgebildet; ihr Profil ent- spricht dem Blechprofil und zumindest die Walzen 6,7 des Walzenpaares sind außerdem entsprechend den herzustellen¬ den Sicken profi 1 iert. Dies ist deutlich der Fig. 4 zu entnehmen, die ein Trapezblech 1 zwischen den Walzen 6 und 7 des Walzenpaares zeigt. Bei dem in Fig. 4 darge- stellten Blech werden die Sicken 5 genau in der Mitte der Außen- bzw. Innengurte und der Stege hergestellt.A roller profiling machine is suitable for bending profiled sheets according to the method according to the invention, which e.g. 2 or 3 consists of a pair of rollers 5, 7, which is preceded by a first bending roller 8 and a second bending roller 9 is arranged downstream. All rollers are designed as profile rollers; their profile corresponds to the sheet metal profile and at least the rollers 6, 7 of the pair of rollers are also profi ned in accordance with the beads to be produced. This can be clearly seen in FIG. 4, which shows a trapezoidal sheet 1 between the rollers 6 and 7 of the pair of rollers. In the case of the sheet metal shown in FIG. 4, the beads 5 are produced exactly in the middle of the outer or inner belts and the webs.
Auf Fig. 2 und 3 zurückkommend sei erläutert, daß etwa die obere Walze 6 ortsfest gelagert'und angetrieben, die untere Walze 7 jedoch gegen die Walze 6 zustel 1bar ist, wodurch der Walzenspalt eingestellt werden kann. Das Blech 1 läuft von rechts in Richtung A über die, hier • nicht angestellte Biegewalze 8 in den Walzenspalt der Walzen 6,7 ein und hierauf über die Biegewalze 9, deren Anstellgrad den Biegeradius bestimmt. Der Walzenspalt bzw. die Wal zenprofi1 ierungen sind so bemessen, daß die während des Biegens auftretenden Stauchungen im Si ckenbereich zur
Sickenbi 1 düng beisteuern. Es wird somit erreicht, daß die unvermeidliche Material Stauchung beim Biegen in genau definierten Zonen in Form von Sicken auftritt.In FIGS. 2 and 3 was Returning explained that about the upper roller 6 fixedly mounted 'and driven, the lower roller 7, however, is zustel 1 bar against the roll 6 can be set so that the nip. The sheet 1 runs from the right in direction A about the, here • non-employee bending roller 8 in the nip of the rollers 6,7 and then through the bending roller 9 whose Anstellgrad determines the bending radius. The roll gap or the roll profi tions are dimensioned such that the compressions occurring during the bending in the sic area to Contribute Sickenbi 1 fertilizer. It is thus achieved that the inevitable material compression occurs in the form of beads when bending in precisely defined zones.
Wie Fig. 3 zeigt, kann mittels der ersten Biegewalze 8 das Blech 1 vorgebogen und mittels der zweiten Biege¬ walze 9 auf den endgültigen Biegeradius gebracht werden. Andererseits ist es auch möglich, zwei Biegestationen der gezeigten Art hintereinanderzuschal ten oder, ein Blech zwei oder mehrmals bei jeweils verschieden angestellten Biegewalzen durch die Vorrichtung laufen zu lassen. Die jeweils günstigste Methode hängt von Art und Stärke des Blechmaterials sowie vom gewünschten Biegeradius ab.As shown in FIG. 3, the sheet 1 can be pre-bent by means of the first bending roller 8 and brought to the final bending radius by means of the second bending roller 9. On the other hand, it is also possible to switch two bending stations of the type shown in succession or to let a sheet run through the device two or more times with bending rollers each set differently. The cheapest method depends on the type and thickness of the sheet material as well as the desired bending radius.
Mit Hilfe des erfindungsgemäßen Verfahrens ließen sich Trapezbleche aus Stahl oder Aluminium ab Blechstärken von 0,6 mm und mit Trapezhöhen bis 200 mm biegen, wobei Biege¬ radien bis unter 450 m erreicht wurden. In manchen Fällen kann auch die Herstellung mehrerer nebeneinanderliegender Sicken von Vorteil sein.With the aid of the method according to the invention, trapezoidal sheets made of steel or aluminum could be bent from sheet thicknesses of 0.6 mm and with trapezoidal heights of up to 200 mm, with bending radii of less than 450 m being achieved. In some cases, the production of several beads next to each other can also be advantageous.
Wenngleich das Verfahren nach der Erfindung an Hand eines Trapezbleches beschrieben ist, kann das Verfahren auch bei anderen Profilformen angewendet werden, z.B. bei Well¬ blechen, Blechen mit Dreieck- oder Rechteckprofil usw. Wesentlich ist bloß, daß die Sicken während des Biegens und im Bereich der beim Biegen auftretenden Druck¬ spannungen ausgebildet werden.
Although the method according to the invention is described using a trapezoidal sheet, the method can also be applied to other profile shapes, e.g. with corrugated sheets, sheets with a triangular or rectangular profile, etc. It is only essential that the beads are formed during bending and in the area of the compressive stresses occurring during bending.
