Abstract

A method and tool for producing a press joint connection, in which portions of the radial lateral walls of an opening of a die are configured as flexible displaceable segments, whereas other sections, when viewed from a periphery of the opening, remain rigidly connected to the die.

Description

Die Erfindung geht aus von einem Verfahren zum Verbinden von Bauteilen wie Platten, Bolzen, Muttern udgl. mit einer Platte unter Bildung einer Druchsetzfügeverbindung nach der Gattung des Hauptanspruchs.The invention is based on a method for joining components such as plates, bolts, nuts and the like. with a plate to form a Druchsetzfügeverbindung according to the preamble of the main claim.

Bei einem bekannten gattungsgemäßen Verfahren US PS 5,046,228 ) sind die abschnittsweise radial nachgiebigen Wände an Federplatten (dort Schneidenteile genannt) angeordnet, wobei einerseits angestrebt ist, dass abgesehen von geringem Platzbedarf die Schneidenteile, die zu verbindenden Bleche nicht aufschneidet und andererseits vermieden wird, dass Späne odgl. zwischen die Schneidenteile und die Matrize gelangen. Nicht zuletzt ist angestrebt, aufgrund der ovalen Form des Verbindungspunktes eine isotrope Festigkeit zu erzielen. Abgesehen davon, dass durch die gegebene Konstruktion mit einer Schneidplatte nicht verhindert werden kann, dass Späne udgl. in den bei Ausschwenken der Schneidplatte gegebenen Spalt gelangen und damit ein Rückschwenken der Schneidplatte verhindern, wirkt sich die isotrope Kräfteverteilung im Verbindungspunkt als Nachteil aus.In a known generic method U.S. Patent 5,046,228 ) are the sections radially resilient walls of spring plates (there called cutting parts), on the one hand strives that apart from small footprint, the cutting parts, the sheets to be joined does not cut and on the other hand is avoided that shavings or the like. between the cutting parts and the die. Last but not least, the aim is to achieve an isotropic strength due to the oval shape of the connection point. Apart from the fact that can not be prevented by the given construction with a cutting tip that chips udgl. get into the given when swinging the cutting plate gap and thus prevent back swinging of the cutting plate, the isotropic force distribution at the connection point has a disadvantage.

Bei einem anderen bekannten Verfahren ( DE OS 35 32 900 ) wird das aus der Platte in die Matrizenöffnung verdrängte Material aufgrund des Bodens der Matrize radial nach außen an die axialen Wände der Matrizenöffnung verdrängt, wobei dieses verdrängte Material den Rand der durch den Stempel bewirkten Durchgangsöffnung hintergreift und dadurch eine feste Verbindung zwischen Bauteil und Platte bildet. Diese Art der Verbindung wird üblicherweise mit Durchsetzfügeverbindung bezeichnet. Sie ist denkbar für die Verbindung von zwei oder mehr übereinanderliegenden Platten oder aber auch zum Verbinden von Bolzen odgl. an einer oder mehreren Platten, wobei der dabei verwendete sogenannte verlorene Stempel entweder aus weichem verformbarem Material besteht, welches ausreichend hart ist um einen Einpressvorgang durch die Platte zu bewirken oder der entsprechende radiale Ausnehmungen aufweist, in die sich das verdrängte Plattenmaterial einformen kann. Der Nachteil dieser sehr schnell und exakt arbeitenden Durchsetzfügeverbindung mit einer Matrize mit unnachgiebigen Begrenzungswänden führt zu Verbindungspunkten begrenzter Elastizität.In another known method ( DE OS 35 32 900 ) displaced from the plate in the die opening material is displaced radially outwardly due to the bottom of the die to the axial walls of the die opening, said displaced material engages behind the edge of the through hole caused by the punch and thereby forms a firm connection between the component and the plate , This type of connection is commonly referred to as a clinch connection. It is conceivable for the connection of two or more superimposed plates or else for connecting bolts or the like. on one or more plates, wherein the so-called lost stamp used in this case either consists of soft deformable material which is sufficiently hard to effect a press-fitting operation through the plate or has the corresponding radial recesses into which the displaced plate material can be formed. The disadvantage of this very fast and accurate clinching connection with a die with unyielding boundary walls results in connection points of limited elasticity.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu entwickeln, bei dem bei Inanspruchnahme nur eines geringen Raumes eine höhere Festigkeit des Verbindungspunktes erzielbar ist. Diese Aufgabe wird durch den Anspruch 1 gelöst.The invention has for its object to develop a method in which when occupying only a small space, a higher strength of the connection point can be achieved. This object is achieved by claim 1.

Das erfindungsgemäße Verfahren mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass bei hoher Funktionssicherheit der Herstellung des Verbindungspunktes eine höhere Elastizität der Verbindung entsteht, so dass endgültig die technischen Scher- und Kopfzugswerte wesentlich höher sind als bei Verbindungspunkten der oben genannten Art. Vorteilhafterweise wird trotz der gewonnenen Elastizität des Verbindungspunktes das hohe Arbeitsvermögen des Verfahrens bzw. des Werkzeuges beibehalten. Durch die erfindungsgemäße Aufteilung des radialen Widerstandes erfolgt im Gegensatz zu den bekannten Verfahren eine abwechselnde und damit unterschiedliche Materialbeanspruchung, die wiederum gleichmäßig auf den Umfang verteilt ist und damit diese höhere Elastizität bewirkt. Die sich dadurch ergebende wellige Form ist zudem optisch sehr ansprechbar.The inventive method with the characterizing features of the main claim has the advantage that at high reliability of the production of the connection point, a higher elasticity of the compound is formed, so that finally the technical shear and Kopfzugwerten are significantly higher than at connection points of the type mentioned above. Advantageously is maintained despite the obtained elasticity of the connection point, the high working capacity of the process or the tool. By the division of the radial resistance according to the invention takes place in contrast to the known methods, an alternating and thus different material stress, which in turn is uniformly distributed over the circumference and thus causes this higher elasticity. The resulting wavy shape is also visually very responsive.

Dem Anspruch 2 ist eine vorteilhafte Ausgestaltung der Erfindung zu entnehmen.The claim 2 is shown in an advantageous embodiment of the invention.

Weitere Vorteile und vorteilhafte Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung, der Zeichnung und den Ansprüchen entnehmbar.Further advantages and advantageous embodiments of the invention are the following description, the drawings and claims removed.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In Fig. 1 ist in Explosionsdarstellung ein Werkzeug dargestellt, nämlich ein Stempel 1 der entsprechend dem Pfeil III für seinen Arbeitshub betätigbar ist und der zwei aufeinanderliegende Platten 2 in eine Öffnung 3 einer Matrize 4 drücken kann. Die Matrize besteht aus feststehenden Abschnitten 5 eines Gesenkes 6 sowie aus axial nach außen schiebbaren Segmenten 7, die durch Blattfedern 8 in die gezeigte Ausgangslage geschoben sind. Die Blattfedern 8 sind über Schrauben 9 an dem Gesenk 6 befestigt und sind in einer Längsnut 11 des Gesenkes 6 angeordnet. Die Öffnung 3 ist nach unten durch einen Boden 12 begrenzt, der vom Gesenk 6 gebildet wird.In Fig. 1 an exploded view of a tool is shown, namely a punch 1 which is actuated according to the arrow III for its working stroke and the two superimposed plates 2 can press in an opening 3 of a die 4. The die consists of fixed sections 5 of a die 6 and of axially outwardly slidable segments 7, by leaf springs 8 in the starting position shown pushed. The leaf springs 8 are fastened by screws 9 to the die 6 and are arranged in a longitudinal groove 11 of the die 6. The opening 3 is bounded below by a bottom 12 which is formed by the die 6.

Wie in Fig. 2 gezeigt, sind die Segmente 7 zwischen den feststehenden Abschnitten 5 des Gesenkes 6 radial verschiebbar geführt, wofür Führungswände 13 an den feststehenden Abschnitten 5 der Matrize dienen. Bei dem Verschieben gleiten die Segmente 7 auf dem Boden 12 der Sacköffnung 3. Bei dieser Bewegung werden die Segmente 7 entsprechend dem Ausweichhub IV verschoben.As in Fig. 2 shown, the segments 7 are radially slidably guided between the fixed portions 5 of the die 6, for which guide walls 13 serve on the fixed portions 5 of the die. When sliding the segments slide 7 on the bottom 12 of the bag opening 3. In this movement, the segments 7 are moved according to the evasive IV.

Die Durchsetzfügeverbindung erfolgt dadurch, daß nachdem die Platten 2 auf das Gesenk 6 aufgelegt sind, durch den Stempel 1 entsprechende Flächenteile in die Sacköffnung 3 bis auf den Boden 12 derselben tiefgezogen werden, um danach gequetscht zu werden, so daß Material radial nach außen an die feststehenden Abschnitten 5 sowie die Segmente 7, die die radiale Wand der Sacköffnung 3 bilden, geschoben werden. Während das verdrängte Material bei den feststehenden Abschnitten 5 der Matrize 4 zurückgehalten werden, wird dazwischenliegendes Material gegen die verschiebbaren Segmente 7 verdrängt, welche nachgeben, so daß das Material nachfließen kann. Hierdurch entsteht wie eingangs beschrieben eine unterschiedliche Struktur des Verbindungspunktes.The clinching connection is made by the fact that after the plates 2 are placed on the die 6, by the stamp 1 corresponding surface parts in the sack opening 3 to the bottom 12 thereof are deep-drawn to be squeezed thereafter, so that material radially outwardly to the fixed sections 5 and the segments 7, which form the radial wall of the bag opening 3, are pushed. While the displaced material is retained at the fixed portions 5 of the die 4, intervening material is displaced against the displaceable segments 7, which give way so that the material can flow. This results in a different structure of the connection point as described above.

In Fig. 3 ist eine Variante des Ausführungsbeispiels dargestellt, bei dem die Blattfeder 8' bei 13 mit dem Gesenk und bei 14 mit dem Segment 7 verschweißt ist. Hierdurch ist eine feste Anbindung vor allem des Segmentes 7' an das Werkzeug gegeben.In Fig. 3 a variant of the embodiment is shown, in which the leaf spring 8 'is welded at 13 with the die and at 14 with the segment 7. As a result, a firm connection especially of the segment 7 'is given to the tool.

In Fig. 4 ist eine zweite Variante dieses Ausführungsbeispiels dargestellt, bei dem statt einer Blattfeder 8' ein Federstab 15 verwendet wird, der in entsprechende Bohrungen 16 des Gesenkes 6 bzw. 17 des Segmentes 7 gesteckt ist.In Fig. 4 a second variant of this embodiment is shown, in which instead of a leaf spring 8 ', a spring rod 15 is used, which is inserted into corresponding holes 16 of the die 6 and 17 of the segment 7.

Während bei dem in Fig. 2 dargestellten Gegenstand vier Segmente 7 vorgesehen sind, weist die Variante nach Fig. 5 nur zwei derartige bewegliche Segmente 7 auf. Entsprechend sind die feststehenden Abschnitte 5' dieser Matrize breiter ausgebildet. Entsprechend ist auch die Struktur des Verbindungsknotens anders.While at the in Fig. 2 illustrated object four segments 7 are provided, the variant according to Fig. 5 only two such movable segments 7. Accordingly, the fixed portions 5 'of this die are made wider. Accordingly, the structure of the connection node is different.
