Description

Die Erfindung betrifft ein Verfahren zum mechanischen Verbinden von zwei Elementen aus Metall, bei welchem die beiden Elemente aus Metall zwischen einem einzigen Satz von zwei Walzen hindurchgeführt werden, insbesondere sind diese beiden Elemente, Schienen für Hängedecken.The invention relates to a method of mechanically connecting two elements of metal, in which the two elements of metal are passed between a single set of two rollers, in particular these two elements are rails for suspended ceilings.

Aus der DE 199 01 015 A1 ist ein Verfahren zum mechanischen Verbinden von zwei Elementen aus Metall bekannt, bei welchem die beiden Elemente aus Metall zwischen einem Satz von zwei Walzen hindurchgeführt werden, wobei das Material der beiden Elemente U-förmig verformt wird.From the DE 199 01 015 A1 For example, there is known a method of mechanically connecting two elements of metal, wherein the two metal elements are passed between a set of two rollers, wherein the material of the two elements is deformed in a U-shape.

Aus der US 2 254 558 , der DE 22 60 339 A1 und aus der DE 36 40 896 A1 ist jeweils ein Verfahren zum Verbinden von Blechen bekannt, bei dem zwei Elemente aus Metall in ein Walzenpaar eingeführt und parallele Schlitze in die Elemente eingestanzt werden. In einem weiteren Schritt wird das Material zumindest eines Elements im Bereich der Schlitze so verformt, dass es das jeweils andere Element überdeckt.From the US 2 254 558 , of the DE 22 60 339 A1 and from the DE 36 40 896 A1 In each case, a method for joining sheets is known in which two metal elements are introduced into a pair of rollers and parallel slots are punched into the elements. In a further step, the material of at least one element in the region of the slots is deformed so that it covers the respective other element.

Aus der DE 44 00 185 B4 ist ein Verfahren bekannt, bei dem zwei Elemente aus Metall in ein erstes Walzenpaar eingeführt werden und dort parallele Schlitze in die Elemente eingestanzt werden und in einem zweiten Walzenpaar das Material der Elemente im Bereich der Schlitze verpresst und quer in Richtung des Freiraums zwischen den Schlitzen verdrängt wird.From the DE 44 00 185 B4 a method is known in which two elements of metal are introduced into a first pair of rollers and there are punched parallel slots in the elements and pressed in a second pair of rollers, the material of the elements in the region of the slots and displaced transversely in the direction of the free space between the slots becomes.

Die der Erfindung zugrunde liegende Aufgabe besteht darin, zwei bandförmige Elemente, insbesondere gerade Schienen für Hängedecken, mechanisch so miteinander zu verbinden, dass der Verbindungsvorgang mit hohem Wirkungsgrad und hoher Geschwindigkeit ausgeführt werden kann und die erhaltenen Produkte einwandfrei feste und steife Verbindungen haben.The object underlying the invention is to combine two band-shaped elements, especially straight rails for suspended ceilings, mechanically together so that the connection process can be performed with high efficiency and high speed and the resulting products have perfectly firm and rigid connections.

Diese Aufgabe wird bei den durch Walzformen verbundenen Elementen, insbesondere Schienen für Hängedecken, mit den entsprechenden, in den Patentansprüchen angegebenen Merkmalen gelöst, wobei zur Herstellung dieser Elemente die verfahrensmäßigen Maßnahmen eingesetzt werden, wie sie in den zugehörigen Patentansprüchen angegeben sind.This object is achieved in the connected by rolling elements, in particular rails for suspended ceilings, with the corresponding features specified in the claims, wherein for the preparation of these elements, the procedural measures are used, as indicated in the accompanying claims.

Gemäß der Erfindung können zwei aneinandergrenzende bandförmige Elemente aus Metall durch eine Reihe von in geringen Abständen vorgesehenen Befestigungspunkten verbunden werden. Die Befestigungspunkte werden dadurch ausgebildet, dass die bandförmigen Elemente aus Metall durch Walzen geführt werden.According to the invention, two adjoining metal belt-shaped elements can be connected by a series of fixing points provided at short intervals. The attachment points are formed by guiding the band-shaped elements of metal through rollers.

Dem Walzendurchgang bzw. -stich sind zwei zusammenwirkende Walzen zugeordnet, von denen die eine eine Reihe von kleinen Stanzwerkzeugen aufweist, die im Abstand um den Walzenumfang herum angeordnet sind.The roller passage is associated with two cooperating rollers, one of which has a series of small punching tools spaced around the circumference of the roller.

Jedes Stanzwerkzeug hat zwei parallele Schneidkanten. Die gegenüberliege Walze hat eine um die Walze herum durchgehende Nut, deren beide Schultern ebenfalls Schneidkanten bilden. Die beiden Walzen sind so angeordnet, daß die Stanzwerkzeugen in die Nut eintreten können, wobei sich die Schneidkanten in unmittelbarer Nähe zueinander befinden. Wenn zwei aneinanderliegende bandförmige Elemente aus Metall zwischen den sich drehenden Walzen hindurchgeführt werden, sorgen die kleinen Stanzwerkzeuge für eine Scherung und Verdrängung von benachbarten Metallabschnitten in die Nut hinein. Die Walzen und der Abstand der Walzen sind so bemessen, daß das Metall um annähernd zwei Blechdioken verdrängt wird.Each punch has two parallel cutting edges. The opposite roller has a continuous groove around the roller, whose two shoulders also form cutting edges. The two rollers are arranged so that the punching tools can enter the groove, wherein the cutting edges are in close proximity to each other. When two adjacent band-shaped elements of metal are passed between the rotating rollers, the small punches provide shearing and displacement of adjacent metal sections into the groove. The rollers and the distance of the rollers are dimensioned so that the metal is displaced by approximately two Blechdioken.

Dieser Prozeß kann dazu verwendet werden, Formteile und Profile günstiger und effizienter herzustellen als dies bisher möglich war.This process can be used to make moldings and profiles cheaper and more efficient than previously possible.

So läßt sich die Reihe der erläuterten Befestigungen am Steg einer Schiene anwenden, der doppelwandig ist, wobei die Schiene die Form eines auf dem Kopf stehenden T hat. Die so hergestellte Schiene ist hinsichtlich des Drehwiderstands stärker.Thus, the series of illustrated fasteners can be applied to the web of a rail which is double-walled, wherein the rail has the shape of an upside-down T. The rail thus produced is stronger in terms of the rotational resistance.

An einer solchen Schiene kann auch ein drittes bandförmiges Element in der beschriebenen Weise festgelegt werden, um einen einzigen Flansch herzustellen und um unnötige Materialkosten im Steg zu vermeiden.On such a rail, a third band-shaped element in the manner described can be set to produce a single flange and to avoid unnecessary material costs in the web.

Schließlich läßt sich auch eine Schiene mit Kastenquerschnitt mit verbessertem Wirkungsgrad herstellen. Dabei kann ein frei liegender Kastenabschnitt mit geringem Gewicht, der gestrichen und endbearbeitet ist, an einer einfachen T-Schiene festgelegt werden.Finally, a rail with box cross-section can be produced with improved efficiency. In this case, an exposed box section with low weight, which is painted and finished, can be fixed to a simple T-rail.

Der in 1 gezeigte Stich besteht aus der Walze 1 und der Walze 2, zwischen denen zwei bandförmige Elemente 3 und 4 aus Metall hindurchgehen. Die Walze 1 hat ein Reihe von Stanzwerkzeugen 5, die um ihren Umfang herum angeordnet sind und sich etwas über die Walzenoberfläche hinaus erstrecken. Jedes Stanzwerkzeug hat einen rechteckigen Querschnitt mit zwei Schneidkanten 6, die, wie in 2 zu sehen ist, zueinander parallel und parallel zur Bewegung der bandförmigen Elemente aus Metall sind.The roll stitch consists of two cooperating rolls, between which the band-shaped elements of Matall to be joined are drawn. The in 1 shown stitch consists of the roller 1 and the roller 2 , between which two band-shaped elements 3 and 4 to go through metal. The roller 1 has a number of punching tools 5 which are arranged around their circumference and extend slightly beyond the roll surface. Each punch has a rectangular cross-section with two cutting edges 6 that, as in 2 can be seen, parallel to each other and parallel to the movement of the band-shaped elements made of metal.

In dem Stich ist die Walze 1 unmittelbar benachbart zur Walze 2 angeordnet. Die Walze 2 hat eine an ihrem Umfang durchgehende Nut 7, die etwas größer als die Breite der Stanzwerkzeuge 5 der Walze 1 ist. Die Außenschultern 8 der Nut bilden Schneidkanten. Wenn die bandförmigen Elemente 3 und 4 aus Metall durch den Stich mit den Walzen 1 und 2 hindurchlaufen, greifen die Stanzwerkzeuge 5 an dem bandförmigen Element an und drücken Metall in die Nut 7 der Walze 2.In the stitch is the roller 1 immediately adjacent to the roller 2 arranged. The roller 2 has a continuous groove on its circumference 7 that is slightly larger than the width of the punching tools 5 the roller 1 is. The outer shoulders 8th the groove form cutting edges. When the band-shaped elements 3 and 4 made of metal through the stitch with the rollers 1 and 2 go through, the punching tools grip 5 on the band-shaped element and press metal into the groove 7 the roller 2 ,

Wenn das Metall in die Nut 7 gedrückt wird, wird es an zwei parallelen Seiten parallel zur Bewegung der Fläche aufgrund der Scherwirkung zwischen den Schneidkanten der Stanzwerkzeuge 6 und den Schneidschultern 8 eingeschnitten, wodurch zwei parallele Schlitze gebildet werden.When the metal in the groove 7 is pressed on two parallel sides parallel to the movement of the surface due to the shearing action between the cutting edges of the punching tools 6 and the cutting shoulders 8th cut, whereby two parallel slots are formed.

Die Walzen und Stanzwerkzeuge des Stichs sind so im Abstand angeordnet und bemessen, daß das Metall nahezu gleich der kombinierten Dicken der zu verbindenden bandförmigen Elemente verdrängt wird. 3 zeigt die Form 10 des ansgeschnittenen und verformten Metalls, die die bandförmigen Elemente im ersten Stich aufgeprägt erhalten.The rollers and punches of the engraving are spaced apart and sized so that the metal is displaced almost equal to the combined thicknesses of the band-shaped elements to be joined. 3 shows the shape 10 of the cut and deformed metal imprinted on the band-shaped elements in the first stitch.
