Abstract

The invention relates to a profile clamp having a clamp strip (2) that has a base (5) with flanks (6, 7) on both sides. A flank angle α is enclosed between the flanks (6, 7) and a clamping head (3, 4) is arranged at each end of the clamp strip (2). For even stress distribution, the flank angle α decreases from a clamping head (3, 4) of the clamp strip (2) up to a region diametrically opposite the clamping heads (3), and then increases again from that region to the other clamping head (4).

Description

Profilschelle  profile clip
Die Erfindung betrifft eine Profilschelle mit einem Schellenband, das einen Boden mit beidseiti gen Flanken aufweist, wobei zwischen den Flanken ein Flankenwinkel eingeschlossen ist und an Enden des Schellenbands jeweils ein Spannkopf angeordnet ist, wobei die Spannköpfe über eine Spanneinrichtung miteinander verbunden sind. The invention relates to a clamp with a clamp band, which has a bottom with flanks on both sides, a flank angle is included between the flanks and a clamping head is arranged at the ends of the clamp band, the clamping heads being connected to one another via a clamping device.
Profilschelle dienen häufig dazu, stumpf aneinanderstoßende Rohrenden axialfest miteinander zu verbinden. Dabei sind an den Rohrenden radial nach außen ragende Flansche vorgesehen, auf die die Profilschelle gesetzt wird. Über ein entsprechendes Profil des Schellenbands der Profilschelle, dass in der Regel v- bis u-förmig ist, werden beim Spannen der Profilschelle radi ale und axiale Spannkräfte erzeugt, wodurch die Rohrenden axial aufeinander zu gedrückt wer- den. Somit wird eine druckfeste Verbindung erhalten. Profile clamps are often used to connect butt jointed pipe ends axially. Flanges projecting radially outwards are provided on the pipe ends, onto which the profile clamp is placed. A corresponding profile of the clamp band of the profile clamp, which is generally V-shaped to U-shaped, generates radial and axial clamping forces when the profile clamp is clamped, as a result of which the pipe ends are pressed axially towards one another. A pressure-resistant connection is thus obtained.
Ein bevorzugtes Einsatzgebiet von Profilschelle liegt im Bereich von Kraftfahrzeugen, beispiels- weise zur Sicherung im Bereich der Abgasleitungen, aber auch anderer Druck führender Lei- tungsverbindungen im Bereich des Motorraums. Die Profilschelle müssen daher über einen re- lativ hohen Temperaturbereich und lange Zeiträume zuverlässig ausreichende Spannkräfte er- zeugen. Da die Motoren von Kraftfahrzeugen immer kompakter werden und gleichzeitig immer höhere Emissionsgrenzen einhalten müssen, steigt die Temperaturbelastung einzelner Bauteile und damit auch der zum Einsatz kommenden Profil sch ei len an. A preferred area of application for profile clamps is in the area of motor vehicles, for example for securing in the area of exhaust pipes, but also in other pressure-carrying lines. connection in the area of the engine compartment. The profile clamp must therefore reliably generate sufficient clamping forces over a relatively high temperature range and over long periods of time. Since the engines of motor vehicles are becoming ever more compact and at the same time have to comply with ever higher emission limits, the temperature load on individual components and thus also on the profile sections used increases.
Um die notwendige Zuverlässigkeit zu erreichen, ist zum einen das Einbringen relativ hoher Spannkräfte erforderlich, zum anderen sollten diese möglichst homogen über die Profilschelle verteilt sein. Dadurch kann auch das Risiko nachlassender Spannkräfte aufgrund von Tempera- turschwankungen geringgehalten werden. In order to achieve the necessary reliability, on the one hand, the introduction of relatively high clamping forces is necessary, on the other hand, these should be distributed as homogeneously as possible over the profile clamp. As a result, the risk of decreasing tension due to temperature fluctuations can be kept low.
Die Erfindung liegt nun die Aufgabe zugrunde, eine Profilschelle bereitzustellen, die eine mög- lichst homogene Spannungsverteilung ermöglicht. Ferner sollen hohe Spannkräfte erzeugt war sein. The invention is based on the object of providing a profile clamp which enables the most homogeneous possible stress distribution. Furthermore, high clamping forces should have been generated.
Gelöst wird diese Aufgabe durch eine Profilschelle mit den Merkmalen des Anspruchs 1. Vor- teilhafte Ausgestaltungen finden sich in den Unteransprüchen. This problem is solved by a profile clamp with the features of claim 1. Advantageous refinements can be found in the subclaims.
Bei einer Profilschelle mit einem Schellenband, das einen Boden mit beidseitigen Flanken auf- weist, wobei zwischen den Flanken ein Flankenwinkel eingeschlossen ist und an Enden des Schellenbands jeweils ein Spannkopf angeordnet ist, wobei die Spannköpfe über eine Span- neinrichtung miteinander verbunden sind, ist erfindungsgemäß vorgesehen, dass der Flanken- winkel ausgehend von einem Spannkopf bis zu einem Bereich diametral gegenüber den Spann- köpfen abnimmt und von dem Bereich bis zum anderen Spannkopf wieder zunimmt. In the case of a profile clamp with a clamp band which has a base with flanks on both sides, a flank angle being enclosed between the flanks and a clamping head being arranged at the ends of the clamp band, the clamping heads being connected to one another via a clamping device It is provided that the flank angle decreases diametrically from one clamping head to an area relative to the clamping heads and increases again from the area to the other clamping head.
Durch diese Ausgestaltung ergibt sich eine bessere, gleichmäßigere Spannungsverteilung. Da- bei wird ausgenutzt, dass sich beim Spannen der Profilschelle ein an die Spannköpfe angren- zender Bereich des Schellenbandes stärker relativ gegenüber den Flanschen der Rohrenden bewegt als der Bereich, der diametral gegenüber den Spannköpfen angeordnet ist. Die bei die- ser Relativbewegung zwischen dem Schellenband und den Flanschen auftretende Reibung hat in den Bereichen mit größerer Bewegung einen größeren Einfluss auf die Spannkräfte als in den Bereichen mit geringer beziehungsweise keiner Bewegung. Dem wird erfindungsgemäß dadurch Rechnung getragen, dass der Flankenwinkel ausgehend vom Spannkopf abnimmt, die Flanken also steiler werden. Im Bereich der steileren Flanken liegen diese dadurch früher am Flansch an als im Bereich der flacheren Flanken, was zu einer früheren Krafteinleitung im Be- reich der steileren Flanken führt. Insgesamt sind damit nicht nur höhere Spannkräfte einbring- bar, es ergibt sich auch eine gleichmäßigere Spannungsverteilung, wodurch auch durch Tem- peraturschwankungen bedingten Längenänderungen besser ausgeglichen werden können. This configuration results in a better, more uniform stress distribution. This takes advantage of the fact that when the profile clamp is tensioned, an area of the clamp band adjoining the tensioning heads moves more relative to the flanges of the pipe ends than the area which is arranged diametrically opposite the tensioning heads. The friction occurring in this relative movement between the clamp band and the flanges has a greater influence on the clamping forces in the areas with greater movement than in the areas with little or no movement. This is taken into account according to the invention in that the flank angle decreases starting from the clamping head, that is to say the flanks become steeper. In the area of the steeper flanks, these are earlier Flange on than in the area of the flatter flanks, which leads to an earlier application of force in the area of the steeper flanks. Overall, not only can higher clamping forces be introduced, there is also a more uniform distribution of stress, which means that changes in length caused by temperature fluctuations can also be better compensated for.
Erfindungsgemäß ändert sich der Flankenwinkel kontinuierlich, insbesondere linear oder quad- ratisch. Durch diese kontinuierliche Änderung des Flankenwinkels werden Spannungsspitzen vermieden und es wird eine gleichmäßige Spannungsverteilung erreicht. According to the invention, the flank angle changes continuously, in particular linearly or square. This continuous change in the flank angle avoids stress peaks and an even stress distribution is achieved.
In einer bevorzugten Ausgestaltung ist das Schellenband durch Ausnehmungen in den Flanken in mindestens zwei Teile geteilt, wobei die Teile einstückig oder über ein Brückenelement mitei- nander verbunden sind. Durch die Teilung des Schellenbands erhält die Profilschelle eine rela- tiv hohe Flexibilität, sodass sie ausreichend weit aufgeweitet werden kann, um problemlos auf die Flansche der Rohrenden aufgesetzt werden zu können. Bei einem zweiteiligen Schellen- band befindet sich dabei die Ausnehmungen üblicherweise diametral gegenüber den Spann- köpfen. In a preferred embodiment, the clamp band is divided into at least two parts by recesses in the flanks, the parts being connected to one another in one piece or via a bridge element. The division of the clamp band gives the profile clamp a relatively high degree of flexibility, so that it can be widened sufficiently to be able to be easily placed on the flanges of the pipe ends. In the case of a two-part clamp band, the recesses are usually located diametrically opposite the clamping heads.
Vorzugsweise ist das Schellenband in mindestens drei Teile geteilt, wobei sich der Flankenwin- kel in zumindest einem der Teile von dem Flankenwinkel in den anderen Teilen unterscheidet. So weisen beispielsweise die beiden zu den Spannköpfen benachbarten Teile einen gleichen, flacheren Flankenwinkel auf als das dritte Teil des Schellenbands, dass diese beiden Teile ver- bindet. Durch eine derartige Ausgestaltung lassen sich die Teile relativ einfach vorkonfigurieren und anschließend über Brückenelemente miteinander verbinden. The clamp band is preferably divided into at least three parts, the flank angle in at least one of the parts differing from the flank angle in the other parts. For example, the two parts adjacent to the clamping heads have the same, flatter flank angle than the third part of the clamp band that connects these two parts. With such a configuration, the parts can be preconfigured relatively easily and then connected to one another via bridge elements.
Bevorzugterweise sind die Spannköpfe einstückig mit dem Schellenband ausgebildet. Die Spannköpfe sind also durch radial nach außen Biegen der Enden des Schellenbands herge- stellt und können so relativ hohe Spannkräfte von der Spanneinrichtung auf das Schellenband übertragen. The clamping heads are preferably formed in one piece with the clamp band. The clamping heads are thus produced by bending the ends of the clamp band radially outwards and can thus transmit relatively high clamping forces from the clamping device to the clamp band.
Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aus dem Wortlaut der Ansprüche sowie aus der folgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnungen. Es zeigen: Further features, details and advantages of the invention emerge from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. Show it:
Fig. 1 eine Seitenansicht einer Profilschelle und Fig. 1 is a side view of a clamp and
Fig. 2 einen Querschnitt eines Schellenbands. In Figur 1 ist eine Profilschelle 1 dargestellt, die ein Schellenband 2 aufweist, dass bei diesem Ausführungsbeispiel vier Teile 2a, 2b, 2c, 2d umfasst. An Enden des Schellenbandes 2 sind Spannköpfe 3, 4 ausgebildet, die über eine nicht dargestellte Spanneinrichtung, insbesondere über eine Spannschraube, miteinander verbunden werden können. Durch Spannen dieser Spanneinrichtung werden die Spannköpfe 3, 4 aufeinander zu bewegt, wodurch sich der Durch- messer der Profilschelle 1 verringert. Fig. 2 shows a cross section of a clamp band. 1 shows a profile clamp 1 which has a clamp band 2 which, in this exemplary embodiment, comprises four parts 2a, 2b, 2c, 2d. Clamping heads 3, 4 are formed at the ends of the clamp band 2 and can be connected to one another via a clamping device, not shown, in particular via a clamping screw. By tensioning this clamping device, the clamping heads 3, 4 are moved towards one another, as a result of which the diameter of the profile clamp 1 is reduced.
Das Schellenband 2 weist ein im Wesentlichen v-förmiges Profil mit einem Boden 5 und beid- seitigen Flanken 6, 7 an seinen axialen Rändern auf, zwischen denen ein Flankenwinkel a aus- gebildet ist (Figur 2). Dieser Flankenwinkel a ändert sich dabei kontinuierlich über den Umfang der Profilschelle. Im Bereich der Spannköpfe 3, 4 beginnend nimmt dieser Flankenwinkel Alpha ab, sodass die Flanken diametral gegenüber den Spannköpfen steiler stehen als in zu den Spannköpfen 3, 4 benachbarten Bereichen. The clamp band 2 has an essentially V-shaped profile with a base 5 and flanks 6, 7 on both sides at its axial edges, between which a flank angle α is formed (FIG. 2). This flank angle a changes continuously over the circumference of the profile clamp. Beginning in the area of the clamping heads 3, 4, this flank angle alpha decreases, so that the flanks are diametrically steeper than the clamping heads than in areas adjacent to the clamping heads 3, 4.
Um eine ausreichende Flexibilität des Schellenbands 2 zu erreichen, sind zwischen den Teilen 2a bis 2d Ausnehmungen 8a, 8b, 8c in den Flanken eingeformt. Diese Ausnehmungen 8a, 8b, 8c können über Brückenelemente oder einen einstückigen, durchgehenden Boden 5 des Schel- lenbands 2 überbrückt werden. Dadurch bilden die Ausnehmungen 8a, 8b, 8c mit den Brücken- elementen bzw. dem Boden stoffschlüssige Gelenke, über die die Profilschelle 1 aufgeweitet werden kann. In order to achieve sufficient flexibility of the clamp band 2, recesses 8a, 8b, 8c are formed in the flanks between the parts 2a to 2d. These recesses 8a, 8b, 8c can be bridged over bridge elements or a one-piece, continuous bottom 5 of the clamp band 2. As a result, the recesses 8a, 8b, 8c form integral joints with the bridge elements or the floor, via which the profile clamp 1 can be widened.
Die Erfindung ist nicht auf eine der vorbeschriebenen Ausführungsformen beschränkt, sondern in vielfältiger Weise abwandelbar. So kann das Schellenband insbesondere aus einer abwei- chenden Anzahl von Teilen bestehen, beispielsweise aus zwei Teilen, die über ein stoffschlüssi- ges Gelenk miteinander verbunden sind. Alternativ einen kontinuierlich zu- bzw. abnehmenden Flankenwinkel könnte auch jedes Teil des Schellenbands jeweils einen konstanten Flankenwin- kel aufweisen. The invention is not limited to one of the above-described embodiments, but can be modified in many ways. The clamp band can in particular consist of a different number of parts, for example of two parts, which are connected to one another via a cohesive joint. As an alternative, a continuously increasing or decreasing flank angle, each part of the clamp band could also have a constant flank angle.
Sämtliche aus den Ansprüchen, der Beschreibung und der Zeichnung hervorgehenden Merk- male und Vorteile, einschließlich konstruktiver Einzelheiten, räumlicher Anordnungen und Ver- fahrenssch ritten, können sowohl für sich als auch in den verschiedensten Kombinationen erfin- dungswesentlich sein. Bezugszei chen l iste All of the features and advantages arising from the claims, the description and the drawing, including constructive details, spatial arrangements and procedural steps, can be essential to the invention both individually and in a wide variety of combinations.
