Abstract

The method involves manufacturing a flat holder (1), which has elements along two opposite side edges, for positive connection. The side edges of the holder are bent and the holder is shaped to give a cross-section corresponding to that of the rod-shaped part (2). The rod-shaped part is guided into the rod-shaped part. The holder is stamped around the rod-shaped part. Preferably, the side edges of the holder to be connected are inclined, so that the inner face is shorter than the outer face. An Independent claim is included for a threaded rod fixed in a holder.

Description

Die Erfindung betrifft ein Verfahren zum Befestigen eines stabförmigen Teiles, vorzugsweise mit zylindrischem Querschnitt, in einer dieses umfassenden Halterung. Sie betrifft ferner einen in einer Halterung befestigten Gewindestab und die Verwendung eines derartigen Gewindestabes.The invention relates to a method for fastening a rod-shaped part, preferably with a cylindrical cross-section, in a holder comprising this. It also affects a threaded rod fastened in a holder and the use of such Threaded rod.

Derartige Verfahren sind bekannt. So ist aus der DE 44 35 466 A1 ein Verfahren zur Herstellung einer Verbindung eines Einsatzteiles in einem rohrartigen Teil mittels Bördelung bekannt, bei dem das Einsatzteil von einem Stirnende her in das rohrartige Teil eingeführt und in Richtung der Längsachse des rohrartigen Teils an einem Anschlag zur Anlage kommt und durch Umbördeln des überstehenden Randes des rohrartigen Teils radial nach innen bezüglich der Längsachse zwischen dem Anschlag und dem umgebördelten Rand festgelegt wird, wobei ein ringartiges Werkzeugteil zur Verwendung kommt. Diese Vorgehensweise ist relativ aufwendig und somit für die Herstellung von Massenteilen wenig geeignet.Such methods are known. DE 44 35 466 A1 describes a method for Establishing a connection of an insert part in a tubular part by means of flanging known in which the insert part is inserted from one end into the tubular part and comes to rest against a stop in the direction of the longitudinal axis of the tubular part and by flanging the protruding edge of the tubular part radially inward with respect the longitudinal axis between the stop and the flanged edge is set, wherein a ring-like tool part is used. This approach is relative complex and therefore not very suitable for the production of mass parts.

Die DE 41 31 385 A1 beschreibt ein Verfahren zum Verstemmen eines Bauteiles in einer insbesondere hohlzylindrischen Aufnahme, wobei die Aufnahme-Seitenwand mittels eines Stempels bereichsweise kaltverformt wird, derart, daß diese das Bauteil abschnittsweise überdeckt, wobei über den Umfang der Aufnahme verteilt zumindest zwei Stempel geneigt zur Aufnahme-Seitenwand in diese hineingetrieben werden. Hierbei wird jedoch nicht eine für alle Anwendungsfälle ausreichende Zugfestigkeit erreicht.DE 41 31 385 A1 describes a method for caulking a component in a in particular hollow cylindrical receptacle, the receptacle side wall by means of a Stamp is cold-formed in some areas, such that the component in sections covered, with at least two stamps inclined distributed over the circumference of the receptacle to be driven into the receiving side wall. However, not one sufficient tensile strength is achieved for all applications.

In der DE 29 12 033 A1 wird ein Verfahren zum Verbinden von zwei Teilen mittels eines Verbindungsstücks beschrieben, bei dem an den Verbindungsflächen der beiden zu verbindenden Teile eine Umfangsnut ausgebildet wird, die an ihren Innenflächen Unebenheiten aufweist und der Werkstoff des Verbindungsstücks durch Pressen und bleibendes Verformen des Verbindungsstücks die Umfangsnut und die Unebenheiten ausfüllt.DE 29 12 033 A1 describes a method for connecting two parts by means of one Connection piece described in which at the connecting surfaces of the two too connecting parts a circumferential groove is formed on its inner surfaces Has unevenness and the material of the connecting piece by pressing and permanent deformation of the connector fills the circumferential groove and the unevenness.

Um hochzugfeste Verbindungen zwischen einem stabförmigen Teil und seiner Halterung zu erreichen, wie sie mit einfachem Verpressen nicht erzielbar sind, werden ferner Schweißverbindungen vorgenommen, die jedoch kostspielig sind und bei mit einer Beschichtung versehenen Bauteilen (z.B. chromatierten Bauteilen) kaum in Frage kommen oder Schraubverbindungen, die ein aufwendiges Handling erfordern.To make high-tensile connections between a rod-shaped part and its holder achieve how they can not be achieved with simple pressing, are also Welded connections made, but are expensive and with one Coated components (e.g. chromated components) are hardly possible or screw connections that require complex handling.

Aufgabe der Erfindung ist es somit, eine hochgradig zugfeste Verbindung zwischen einem stabförmigen Teil und seiner Halterung zu schaffen, die kostengünstig herstellbar, bauteilminimiert und auch bei bereits mit einer Beschichtung versehenen Teilen realisierbar ist.The object of the invention is therefore to provide a highly tensile connection between one to create rod-shaped part and its holder, which can be produced inexpensively, minimized components and can also be implemented with parts that have already been coated is.

Diese Aufgabe wird erfindungsgemäß durch folgende Verfahrensschritte gelöst:

  • a.) Herstellen einer flächigen Halterung, die an zwei gegenüberliegenden Seitenkanten Elemente zum formschlüssigen Ineinandergreifen aufweist,
  • b.) Hochbiegen der Seitenkanten der Halterung,
  • c.) Formen der Halterung zu einer dem stabförmigen Teil entsprechenden Querschnittsform,
  • d.) Einführen des stabförmigen Teiles in die Halterung,
  • e.) Verprägen der Halterung um das stabförmige Teil.
    • According to the invention, this object is achieved by the following method steps:
  • a.) Manufacture of a flat holder which has elements for interlocking engagement on two opposite side edges,
  • b.) bending up the side edges of the bracket,
  • c.) forming the holder into a cross-sectional shape corresponding to the rod-shaped part,
  • d.) inserting the rod-shaped part into the holder,
  • e.) Stamp the bracket around the rod-shaped part.

    • Auf diese Weise wird eine hochgradig zugfeste Verbindung (Zuglast von mehr als zwei Tonnen ohne Lösen der Verbindung möglich) zwischen dem stabförmigen Teil und der Halterung erreicht, die dennoch kostengünstig herstellbar und auch bei bereits beschichteten (z.B. chromatierten) Teilen anwendbar ist.In this way, a highly tensile connection (tensile load of more than two Tons possible without loosening the connection) between the rod-shaped part and the Bracket achieved, which is still inexpensive to manufacture and even with already coated (e.g. chromated) parts is applicable.

    Eine Weiterbildung der Erfindung besteht darin, daß die beiden gegenüberliegenden Seitenkanten zu einer Seite hin abgeschrägt sind, so daß eine Innenseite mit einer kleineren Fläche als die der Außenseite gebildet wird. A further development of the invention is that the two opposite Side edges are chamfered to one side, so that an inside with a smaller one Area than that of the outside is formed.

    Hierdurch wird insbesondere bei kleinen Dimensionen des stabförmigen Teils eine weitere Steigerung der Zugfestigkeit erreicht, da die Halterung das stabförmige Teil besser umschließt.This makes another one, especially in the case of small dimensions of the rod-shaped part Increased tensile strength achieved because the bracket better the rod-shaped part encloses.

    Es liegt im Rahmen der Erfindung, daß das Hochbiegen der Seitenkanten und Formen der Halterung durch Rollformen erfolgt.It is within the scope of the invention that the bending of the side edges and shapes of the Bracket done by roll molding.

    Es ist vorteilhaft, daß das Verprägen der Halterung um das stabförmige Teil mindestens zwei um 90° versetzte Preßvorgänge umfaßt.It is advantageous that the stamping of the holder around the rod-shaped part is at least two includes pressing operations offset by 90 °.

    Durch die beiden gegeneinander versetzten Preßvorgänge wird eine bessere Verbindung zwischen der Halterung und dem stabförmigen Teil erreicht als mit einem einzigen Preßvorgang.The two pressing processes offset against each other result in a better connection achieved between the bracket and the rod-shaped part than with a single Pressing process.

    Eine Ausbildung der Erfindung besteht darin, daß das stabförmige Teil eine vorzugsweise radiale Profilierung, insbesondere ein Gewinde aufweist.An embodiment of the invention is that the rod-shaped part preferably one has radial profiling, in particular a thread.

    Hierdurch wird es möglich, daß Material der Halterung in die Profilierung des stabförmigen Teils hineingepreßt wird, was die Verbindung zwischen den beiden Teilen verbessert.This makes it possible that material of the holder in the profile of the rod-shaped Part is pressed in, which improves the connection between the two parts.

    Es ist erfindungsgemäß, daß das stabförmige Teil ein Gewindestab ist.It is in accordance with the invention that the rod-shaped part is a threaded rod.

    Im Rahmen der Erfindung liegt auch ein in einer Halterung befestigter Gewindestab, der in einem Verfahren gemäß der Erfindung hergestellt wurde.Within the scope of the invention is also a threaded rod fastened in a holder, which in a method according to the invention.

    Schließlich ist auch die Verwendung eines in einer Halterung befestigten Gewindestabes für das Verstellen eines Bauteiles erfindungsgemäß.Finally, the use of a threaded rod fastened in a holder is also suitable for the adjustment of a component according to the invention.

    Im folgenden wird ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens anhand von Zeichnungen dargestellt.An exemplary embodiment of the method according to the invention is described below with reference to Drawings shown.

    Wie aus Fig. 1a ersichtlich, wird zunächst die Halterung 1 für das stabförmige Teil 2 hergestellt, was z.B. durch Stanzen erfolgen kann. An zwei einander gegenüberliegenden Seitenkanten 3, 4 weist die zunächst noch flächige Halterung 1 Elemente 5, 6 zum flächigen Ineinandergreifen auf, wobei das vorstehende Element 5 in die entsprechende Ausbuchtung 6 eingreifen kann und die hierbei entstehende Verbindung auf Zug belastbar ist. Selbstverständlich können noch weitere derartige Elemente 5, 6 auch in anderer Form über die Seitenkanten 3, 4 verteilt sein.As can be seen from FIG. 1 a, the holder 1 for the rod-shaped part 2 is first manufactured, e.g. can be done by punching. On two opposite one another Side edges 3, 4 have the initially flat support 1 elements 5, 6 for the flat Interlocking, whereby the projecting element 5 into the corresponding bulge 6 can intervene and the resulting connection is resilient to train. Of course, other such elements 5, 6 can also be in a different form the side edges 3, 4 can be distributed.

    Zusätzlich ist es zumindest bei kleinen Abmessungen des stabförmigen Teils 2 sinnvoll, die Seitenkanten 3, 4 der Halterung 1 zu einer Seite hin abzuschrägen, so daß eine Innenseite 7 und eine Außenseite 8 gebildet werden, wobei die Innenseite 7 eine kleinere Fläche aufweist als die Außenseite 8. Hierdurch wird erreicht, daß bei Erstellen der Verbindung zwischen der Halterung 1 und dem stabförmigen Teil 2 die Seitenkanten 3, 4 über ihre gesamte Höhe aneinanderstoßen und somit eine bessere Verbindung erreicht wird als bei geraden Seitenkanten 3, 4.In addition, it is useful, at least in the case of small dimensions of the rod-shaped part 2, that Chamfer side edges 3, 4 of the holder 1 to one side so that an inside 7 and an outer side 8 are formed, the inner side 7 having a smaller area than the outside 8. This ensures that when creating the connection between the Bracket 1 and the rod-shaped part 2, the side edges 3, 4 over their entire height butt and thus a better connection is achieved than with straight Side edges 3, 4.

    Im nächsten Schritt (Fig. 1b) werden die Seitenkanten 3, 4 hochgebogen, so daß die Innenseite 7 im Innern der nunmehr u-förmigen Halterung 1 angeordnet ist. Dieses Hochbiegen kann z.B. durch Rollformen erfolgen.In the next step (Fig. 1b), the side edges 3, 4 are bent up so that the Inside 7 is arranged inside the now U-shaped bracket 1. This Bending up can e.g. done by roll forming.

    Anschließend (Fig. 1c) wird die Halterung 1 zu einer dem stabförmigen Teil 2 entsprechenden Querschnittsform geformt, was im vorliegenden Beispiel bedeutet, daß die Halterung 1 einen kreisförmigen Querschnitt erhält, wie ihn auch das stabförmige Teil 2 aufweist. Hierbei greifen die Elemente 5, 6 bereits ineinander, so daß der Querschnitt im wesentlichen fixiert ist. In diesem Stadium ist allerdings der Querschnitt der Halterung 1 noch so groß, daß es möglich ist, das stabförmige Teil 2 durch eine der offenen Seiten in die vorgeformte Halterung 1 einzubringen, was nach Abschluß der Formgebung erfolgt. Then (Fig. 1c), the bracket 1 to a corresponding to the rod-shaped part 2 Shaped cross-sectional shape, which means in the present example that the holder 1 a receives circular cross section, as it has the rod-shaped part 2. Here the elements 5, 6 already interlock, so that the cross section is essentially fixed is. At this stage, however, the cross section of the holder 1 is still so large that it is possible, the rod-shaped part 2 through one of the open sides in the preformed Introduce bracket 1, which takes place after completion of the shaping.

    Nun (Fig. 1d) wird durch einen ersten Preßvorgang das stabförmige Teil 2 mit der Halterung 1 seitlich, d.h. um 90° gegenüber der durch die Seitenkanten 3, 4 gebildeten Öffnung 9 versetzt, verpreßt, wobei die Halterung 1 eine eiförmige Form annimmt.Now (Fig. 1d) is the rod-shaped part 2 with the bracket by a first pressing process 1 on the side, i.e. by 90 ° with respect to the opening 9 formed by the side edges 3, 4 offset, pressed, the holder 1 assuming an egg-shaped shape.

    Schließlich erfolgt ein weiterer Preßvorgang (Fig. le), der gegenüber dem ersten Preßvorgang um 90° versetzt ist, d.h. im Bereich der durch die aneinanderstoßenden Seitenkanten 3, 4 gebildeten Öffnung 9 sowie des dieser gegenüberliegenden Bereiches 10 erfolgt. Hierbei wird die Öffnung 9 durch das fließende Material geschlossen und die Halterung 1 zugfest mit dem stabförmigen Teil 2 verbunden.Finally, there is a further pressing process (Fig. Le) compared to the first pressing process is offset by 90 °, i.e. in the area of the abutting side edges 3, 4 Formed opening 9 and the area 10 opposite this takes place. Here will the opening 9 closed by the flowing material and the holder 1 tensile with the rod-shaped part 2 connected.

    Das Verfahren eignet sich insbesondere zum Befestigen von Gewindestäben in einer Halterung, da das Material der Halterung in die radiale Profilierung des Gewindestabes während des Verprägens einfließen kann, wodurch ein Formschluß zwischen beiden Teilen erreicht wird. Auch bei bereits mit einer Beschichtung versehenen (z.B. chromatierten) Teilen kann das Verfahren angewendet werden, was für viele Anwendungen von Vorteil ist.The method is particularly suitable for fastening threaded rods in a Bracket because the material of the bracket in the radial profiling of the threaded rod can flow during embossing, creating a positive connection between the two parts is achieved. Even with parts that have already been coated (e.g. chromated) the method can be used, which is advantageous for many applications.

    Fig. 2 zeigt einen nach dem erfindungsgemäßen Verfahren hergestellten Gewindestab 2, der in einer Halterung 1 befestigt ist.Fig. 2 shows a threaded rod 2 produced by the method according to the invention, the is fastened in a holder 1.
