Abstract

For pulling concave dents out of sheet metal, a device is used that has a base body made of metal on which a pulling device engages. In the base body at least one, preferably a plurality of pull electrodes are disposed, which are guided in passages and can be moved in relation to the base body. The electrodes are welded together with the sheet metal and subsequently a pulling force is applied to the base body such that the dent is pulled out. The contact surface between the base body and the electrodes is provided with a coating that firmly bonds with the surface of the base body, particularly an anodization.

Description

Die Erfindung betrifft eine Vorrichtung zum Herausziehen von Beulen aus Blech, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for extracting bumps from sheet metal, according to the preamble of claim 1.

Insbesondere bei Kraftfahrzeugen kann es vorkommen, dass Karosserien oder sonstiger Blechteile Beulen erhalten. Diese Beulen können mit speziellen Vorrichtungen herausgezogen werden, was den Vorteil hat, dass man nicht auf die Rückseite des Karosseriebauteils zugreifen muss.In particular, in motor vehicles, it may happen that bumpers or other sheet metal parts get bumps. These bumps can be pulled out with special devices, which has the advantage that you do not have to access the back of the body component.

Es ist bereits eine Vorrichtung zum Herausziehen von Beulen aus Blech bekannt, bei der Zugelektroden, die mit dem Blech verschweißt werden, in einem aus Kunststoff bestehenden Grundkörper angeordnet sind ( DE 10320512 ). Bei dem Anschweißen der Zugelektroden entwickelt sich Wärme, die sich auf den aus Kunststoff bestehenden Grundkörper überträgt. An diesem Kunststoffkörper wird dann aber gezogen, um die Kräfte auf das Blech zu übertragen. Es besteht hier die Gefahr, dass der Grundkörper durch die ständigen und stetigen Erwärmungen schmilzt oder sogar bricht.A device for extracting bumps from sheet metal is already known, in which pulling electrodes, which are welded to the metal sheet, are arranged in a basic body made of plastic ( DE 10320512 ). When the pull electrodes are welded on, heat is generated which is transferred to the base made of plastic. But this plastic body is then pulled to transfer the forces to the plate. There is the danger here that the base body melts or even breaks through the constant and steady warming.

Ebenfalls bekannt ist es, einen metallischen Grundkörper mit Durchgangsbohrungen für die Elektroden zu verwenden, und in diese Durchgangsbohrungen Isolierbuchsen aus Kunststoff einzusetzen ( EP 1157758 ). Auch hier besteht die Gefahr, dass aufgrund der Wärmeentwicklung die Kunststoffbuchsen beschädigt werden, sich verformen und dadurch die Vorrichtung unbrauchbar wird.It is also known to use a metallic base body with through-holes for the electrodes, and to insert insulating bushes made of plastic in these through-holes ( EP 1157758 ). Again, there is a risk that the plastic bushings are damaged due to the heat, deform and thus the device is unusable.

Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung dieser Art zu schaffen, die bei einfachem Aufbau eine erhöhte Betriebssicherheit aufweist.The invention is based on the object to provide a device of this type, the increased reliability with a simple structure having.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Vorrichtung mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.To solve this problem, the invention proposes a device with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.

Die Erfindung schlägt also eine Vorrichtung vor, bei der der Grundkörper, der die hauptsächliche Belastung beim Herausziehen aufbringen beziehungsweise erfahren muss, aus einem festen Werkstoff besteht. Die Isolierung wird von einer Beschichtung übernommen, die damit fester Bestandteil des Grundkörpers wird. Dies gilt insbesondere dann, wenn sich die Beschichtung durch eine Bearbeitung der Oberfläche des Grundkörpers selbst herstellen lässt. Es kann sich also auch um eine Schicht des Grundkörpers handeln. Diese Schicht beziehungsweise Beschichtung ist hitzebeständig, was insbesondere bedeutet, dass sie sich von dem Grundkörper auch bei einer hohen thermischen Belastung nicht löst. Sie kann die Temperatur auch auf den Grundkörper selbst übertragen, der wegen seiner Eigenschaften auch unter einer beim Schweißen auftretenden Wärmebelastung seine Festigkeit nicht verliert. Auch Beschädigungen, wie sie beim Einsetzen oder Auswechseln von Schweißelektroden in einen mit Isolierbuchsen versehenen Grundkörper bei unsachgemäßer der Behandlung auftreten könnten, können hier nicht auftreten.Thus, the invention proposes a device in which the base body, which has to apply or must experience the main load when pulling out, consists of a solid material. The insulation is taken over by a coating, which thus becomes an integral part of the basic body. This applies in particular if the coating can be produced by machining the surface of the main body itself. It can therefore also be a layer of the base body. This layer or coating is heat-resistant, which means in particular that it does not detach from the base body even at high thermal stress. It can also transfer the temperature to the base body itself, which does not lose its strength due to its properties under a heat load occurring during welding. Damage, such as might occur when inserting or replacing welding electrodes in a provided with insulating bushing body inappropriate treatment, can not occur here.

Die erwähnte Berührungsfläche zwischen dem Grundkörper und dem Zugelement ist, wenn die Zugelemente in Bohrungen angeordnet sind, die Wand der Bohrung und, da die Zugelemente als Zugelektroden auch einen Kopf aufweisen, die Fläche, auf der die Unterseite des Kopfs beim Ziehen aufliegt.The mentioned contact surface between the main body and the tension element is, when the tension elements are arranged in bores, the wall of the bore and, since the tension elements as traction electrodes also have a head, the surface on which the underside of the head rests when pulling.

Eine Möglichkeit, wie die Beschichtung ausgebildet sein kann, ist eine Eloxierung.One way in which the coating may be formed is an anodization.

Eine andere Möglichkeit, die ebenfalls geeignet ist und von der Erfindung vorgeschlagen wird, ist eine keramische Beschichtung. Eine weitere von der Erfindung vorgeschlagene Möglichkeit ist eine Pulverbeschichtung.Another possibility which is also suitable and proposed by the invention is a ceramic coating. Another possibility proposed by the invention is a powder coating.

Eine weitere von der Erfindung vorgeschlagene Beschichtungsmöglichkeit besteht darin, eine katodische Tauchlackierung (KTL) durchzuführen.Another coating option proposed by the invention is to perform a cathodic dip coating (CDL).

Es wurde erwähnt, dass es in erster Linie auf die Berührungsfläche zwischen dem Grundkörper und dem Zugelement ankommt. Es kann aber aus Praktikabilitätsgründen sinnvoll sein, die gesamte Oberfläche des Grundkörpers mit der Beschichtung beziehungsweise der Schicht zu versehen.It has been mentioned that it depends primarily on the contact surface between the main body and the tension element. However, it may be useful for Praktikabilitätsgründen to provide the entire surface of the body with the coating or the layer.

Als Material für den Grundkörper kommt insbesondere Aluminium beziehungsweise eine Aluminiumlegierung infrage, darüber hinaus auch Stahl, Messing, Gusswerkstoff und auch Titan.As a material for the body is in particular aluminum or an aluminum alloy in question, in addition also steel, brass, cast iron and titanium.

Weitere Merkmale, Einzelheiten und Vorzüge der Erfindung ergeben sich aus den Ansprüchen und der Zusammenfassung, deren beider Wortlaut durch Bezugnahme zum Inhalt der Beschreibung gemacht wird, der folgenden Beschreibung bevorzugter Ausführungsformen der Erfindung sowie anhand der Zeichnung. Hierbei zeigen:

Further features, details and advantages of the invention will become apparent from the claims and the abstract, the wording of which is incorporated by reference into the content of the description, the following description of preferred embodiments of the invention and with reference to the drawing. Hereby show:
FIG. 1
a cross section through a device proposed by the invention;
FIG. 2
the side view of a device according to the invention;
FIG. 3
one of the FIG. 1 corresponding section through a modified Embodiment.

Figur 1 zeigt einen Schnitt durch die Vorrichtung nach der Erfindung. Diese enthält einen Grundkörper 1, der aus Metall besteht. Der Grundkörper 1 ist leistenförmig aufgebaut und hat eine Längsrichtung, die senkrecht zur Zeichnungsebene der Figur 1 verläuft. Der Grundkörper 1 weist eine ebene Oberseite 2 auf. Die gegenüberliegende Vorderseite beziehungsweise Unterseite 3 ist schmaler ausgebildet, da die Seitenflächen 4 des Grundkörpers 1 zur Vorderseite 3 hin abgeschrägt verlaufen. Dadurch kann man, wenn man von schräg oben sieht, die aus der Vorderseite 3 des Grundkörpers 1 herausragende Spitze 5 des Zugelements 6 besser sehen. Das Zugelemente 6 weist die Form eines Stifts auf, der im Bereich seiner Spitze 5 sich im Querschnitt verjüngt. An der gegenüberliegenden Seite enthält das Zugelemente 6 einen Kopf 7, der nach Art eines Schraubenkopfs ausgebildet ist. Er enthält also einen Schlitz 8, in denen man einen Schraubendreher einsetzen kann. Die aus der um 90° versetzten Richtung zu sehende Kontur, siehe Figur 1 und Figur 3, ist so ausgebildet, dass eine Vertiefung 9 gebildet ist. Hier kann eine Schweißelektrode eingesetzt werden. FIG. 1 shows a section through the device according to the invention. This contains a base body 1, which consists of metal. The main body 1 is strip-shaped and has a longitudinal direction perpendicular to the plane of the FIG. 1 runs. The base body 1 has a flat upper side 2. The opposite front side or lower side 3 is narrower, since the side surfaces 4 of the main body 1 are tapered toward the front side 3. As a result, it is possible to better see the tip 5 of the tension element 6 projecting from the front side 3 of the main body 1, if one looks diagonally from above. The tension elements 6 has the shape of a pin which tapers in cross-section in the region of its tip 5. On the opposite side, the tension elements 6 includes a head 7, which is designed in the manner of a screw head. So it contains a slot 8, in which you can use a screwdriver. The contour to be seen from the 90 ° offset direction, see FIG. 1 and FIG. 3 is formed so that a recess 9 is formed. Here, a welding electrode can be used.

Von der Vorderseite 3 des Grundkörpers 1 führt eine Stufenbohrung durch den Grundkörper 1, in deren von der Oberseite 2 ausgehenden Bereich das Zugelement 6 geführt ist. In dem verbreiteten Teil der Stufenbohrung ist eine Druckfeder 10 untergebracht, deren eines Ende sich auf dem Boden der Stufenbohrung abstützt, während ihr anderes enger gewickeltes Ende in eine Umfangsnut 11 des Zugelements 6 eingreift.From the front side 3 of the main body 1, a stepped bore passes through the main body 1, in which region of the upper side 2 the tension element 6 is guided. In the common part of the stepped bore a compression spring 10 is housed, one end of which rests on the bottom of the stepped bore, while their other more closely wound end engages in a circumferential groove 11 of the tension element 6.

In beiden einander gegenüberliegenden parallelen Seitenflächen 4 des Grundkörpers 1 ist jeweils eine Nut 12 ausgebildet, deren Längsrichtung senkrecht zur Zeichnungsebene der Figur 1 verläuft. Beide Nuten 12 weisen die gleiche Querschnittsform und Querschnittsgröße auf, sind nur spiegelbildlich zueinander ausgebildet. Die in Figur 1 obere Nutflanke 13 beider Nuten 12 bildet einen Hinterschnitt für das Angreifen einer Zugeinrichtung, mit deren Hilfe der Grundkörper 1 und damit ein an dem Blech angeschweißtes Zugelement nach oben gezogen werden kann.In both opposing parallel side surfaces 4 of the base body 1, a groove 12 is formed in each case, the longitudinal direction perpendicular to the plane of the drawing FIG. 1 runs. Both grooves 12 have the same cross-sectional shape and cross-sectional size, are only mirror images of each other. In the FIG. 1 upper groove flank 13 of both grooves 12 forms an undercut for engaging a traction device, with the aid of the base body 1 and thus a welded to the sheet tension element can be pulled upwards.

Aus Figur 2 ist zu entnehmen, dass in dem Grundkörper 1 mehrere derartige Zugelemente 6 parallel zueinander angeordnet sind. Diese sind unabhängig voneinander in jeweils einer Durchgangsbohrung verschiebbar gelagert.Out FIG. 2 It can be seen that in the base body 1 a plurality of such tension elements 6 are arranged parallel to each other. These are mounted independently displaceable in each case in a through hole.

Nach dem Verschweißen der Zugelemente 6 mit einem Blech 14 wird in die Längsnuten 12 beispielsweise ein Zugadapter eingeschoben, der dann mithilfe eines Hebels oder einer Zange nach oben gezogen wird.After welding the tension elements 6 with a plate 14, for example, a tension adapter is inserted into the longitudinal grooves 12, which is then pulled by means of a lever or a pair of pliers upwards.

Man kann den Figuren entnehmen, dass beim Ziehen an dem Grundkörper die Zugelemente 6 mitgenommen werden, da sie mit der Unterseite ihres Kopfs 7 auf der Oberseite 2 des Grundkörpers aufliegen. Die Zugelemente berühren den Grundkörper 1 also an der Oberseite 2 des Grundkörpers und an der Wand der Bohrung. In dem verbreiteten Teil der Bohrung tritt eine Berührung durch die Druckfeder 10 auf.It can be seen from the figures that when pulling on the main body, the tension elements 6 are taken along, since they rest with the underside of their head 7 on the upper side 2 of the main body. The tension elements thus touch the main body 1 on the upper side 2 of the main body and on the wall of the bore. In the common part of the bore comes into contact by the compression spring 10.

Die Erfindung schlägt nun vor, wie dies in Figur 1 angedeutet ist, die gesamte Oberfläche des aus Metall bestehenden Grundkörpers 1 mit einer angedeuteten Beschichtung 15 zu versehen, bei der es sich um eine isolierende hitzebeständige und sich fest mit dem Grundkörper 1 verbindende Schicht oder Beschichtung handelt.The invention now proposes, as in FIG. 1 is indicated to provide the entire surface of the existing metal body 1 with an indicated coating 15, which is an insulating heat-resistant and firmly connected to the base body 1 layer or coating.

Bei der Ausführungsform der Figur 3 ist diese Schicht oder Beschichtung 15 nur auf der Oberseite 2 des Grundkörpers, also der Fläche, wo die Unterseite des Kopfs 7 der Zugelemente 6 zur Anlage kommt, und an der Wand der Stufenbohrung vorhanden.In the embodiment of the FIG. 3 is this layer or coating 15 only on the top 2 of the body, so the area where the bottom of the head 7 of the tension elements 6 comes to rest, and on the wall of the stepped bore.
