Description

Die Erfindung betrifft eine Matrize für einen Werkzeugsatz zum mechanischen Fügen nach dem Oberbegriff des Anspruchs 1.The invention relates to a die for a tool set for mechanical Joining according to the preamble of claim 1.

Aus der EP 0 779 843 B1 ist ein Werkzeugsatz zum Herstellen von Fügestellen an plattenförmigen Teilen bekannt, der ein erstes oberes Werkzeugteil mit einem Stempel und ein zweites unteres Werkzeugteil mit einer runden Matrize aufweist. Die Matrize besitzt einen Amboß mit einem Amboßkörper, an dem, ein ringförmiges Element mit einer kopfseitigen Gleitfläche und einer bodenseitigen Anschlußfläche vorgesehen sind. Einzelne, den Amboß umgebende, ringabschnittförmige Matrizensegmente besitzen Ausnehmungen für ein konzentrisches, eine längsgerichtete Bewegung der Matrizensegmente erlaubendes Flanschen derselben an das ringförmige Element, wobei jedes Matrizensegment sich an der kopfseitigen Gleitfläche unter Federvorspannung verschiebbar abstützt, wozu eine elastische Einrichtung die Matrizensegmente an die seitliche Fläche des Ambosses anlegt.From EP 0 779 843 B1 a tool set for producing joints is plate-shaped parts known, the first upper tool part with a Stamp and a second lower tool part having a round die. The female part has an anvil with an anvil body on which annular element with a head-side sliding surface and a bottom side Pad are provided. Single, surrounding the anvil, Ring-segment-shaped die segments have recesses for a concentric, a longitudinal movement of the die segments allowing flanges thereof to the annular member, each Matrizensegment on the head-side sliding surface under spring preload slidably supported, including an elastic means the Matrizensegmente the lateral surface of the anvil applies.

Nachteilig dabei ist, daß die Matrizensegmente aufgrund ihres ungünstigen Verhältnisses von Bauhöhe zu radialer Erstreckung eher zum Kippen als zum radialen Gleiten neigen und dabei verkanten und dadurch verklemmen können. Die Abstützung der Matrizensegmente an dem Amboßkörper verkleinert sich bei der längsgerichteten Auswärtsbewegung, da die Matrizensegmente aus der Führung zumindest teilweise herauslaufen. Außerdem muß der Matrizengrundkörper im Amboßbereich hinterschnitten werden, um die Matrizensegmente gegen axiales Verschieben zu sichern. Eine erhöhte Bruchgefahr des Matrizengrundkörpers ist die Folge. Die Standzeiten einer solchen Matrize sind deshalb niedrig. Ferner verlangt das ringförmige Element an dem Amboßkörper eine vergrößerte Bauhöhe, wodurch die Zugänglichkeit zu Fügestellen in schachtartigen Bauteilen stark beschränkt wird.The disadvantage here is that the die segments due to their unfavorable Ratio of height to radial extent tipping rather than tilt radial slide and thereby cant and thereby jam. The support of the die segments on the anvil body decreases in size the longitudinal outward movement, since the die segments from the Lead at least partially run out. In addition, the must Matrizengrundkörper be undercut in the anvil area to the Secure die segments against axial displacement. An increased Risk of breakage of Matrizengrundkörpers is the result. The lifetimes of a such matrix are therefore low. Furthermore, the annular element requires the anvil body an increased height, whereby the accessibility to Joint in shaft-like components is severely limited.

Aus der WO 01/36124 A2 ist ein gattungsgemäßer Werkzeugsatz zum Herstellen von Fügestellen an plattenförmigen Teilen bekannt, der eine Rundmatrize umfaßt. Einzelne, den Amboß umgebende, ringabschnittförmige Matrizensegmente sind gegen eine Federvorspannung nach außen verschiebbar auf einer Stützfläche angeordnet. Die radiale Verschiebbarkeit der Matrizensegmente nach außen wird dabei begrenzt durch einen die Stützfläche ummantelnden Anschlag, der von einer Matrizenhülse gebildet wird. Der Anschlag dient femer dazu, eine axiale Bewegung der Matrizensegmente bei ihrer Verschiebung nach außen zu verhindern, wozu dieser vorspringende Führungen aufweist, die in Hinterschneidungen der Matrizensegmente eingreifen. Nachteilig dabei ist wieder, daß die Matrizensegmente gegenüber den vorspringenden Führungen verkanten und dadurch verklemmen können. From WO 01/36124 A2 is a generic tool set for manufacturing known from joints on plate-shaped parts, comprising a round die. Individual, the anvil surrounding ring-shaped die segments are against a spring bias to the outside displaced on a support surface arranged. The radial displaceability of the die segments to the outside becomes limited by a the support surface enclosing stop, the a Matrizenhülse is formed. The stop is also used to an axial Movement of the die segments in their displacement to the outside prevent what this projecting guides, the in Engage undercuts of the die segments. The disadvantage is again, in that the die segments tilt relative to the projecting guides and thereby jam.

Weiterhin ist aus DE 694 08 080 T2 ein gattungsgemäßer Werkzeugsatz zum Herstellen von Fügestellen an plattenförmigen Teilen bekannt, der eine Rundmatrize umfaßt. Die Matrize weist vier Matrizensegmente auf, die von einem Gehäuse umgeben sind. Das Gehäuse ist mit Langlöchern ausgestattet, wobei zwischen jeweils zwei Langlöchern Zapfen sich in das Innere des Gehäuses erstrecken. Diese Zapfen greifen in Nuten, die an den Matrizensegmenten ausgebildet sind. Bei einer Auswärtsbewegung der Matrizensegmente gegen eine Federvorspannung sind Kanten der Matrizensegmente in die Langlöcher des Matrizengehäuses verfahrbar, wobei die in die Matrizensegmente eingreifenden Zapfen einer Drehbewegung der Matrizensegmente entgegenwirken.Furthermore, from DE 694 08 080 T2 a generic tool set for manufacturing known from joints on plate-shaped parts, a round die includes. The die has four die segments, that of a housing are surrounded. The housing is equipped with oblong holes, with between two slots each pin extend into the interior of the housing. These pins engage in grooves formed on the die segments. In an outward movement of the die segments against a Spring preload are edges of the die segments in the slots of the Matrizengehäuses movable, wherein the engaging in the die segments Counteract pins of a rotational movement of the die segments.

Nachteilig ist hier, daß die Matrizensegmente gegenüber den Langlöchern verkanten können, da die Verschiebung gegen einen Anschlag erfolgt, wobei die Matrizensegmente eine Führung allein durch einseitig angreifende Zapfen erhalten.The disadvantage here is that the Matrizensegmente compared to the oblong holes can tilt, since the displacement takes place against a stop, wherein the Die segments a guide solely by unilaterally attacking pins receive.

Aufgabe der Erfindung ist es daher, eine Matrize für einen Werkzeugsatz zum mechanischen Fügen nach dem Oberbegriff des Anspruchs 1 zu schaffen, die eine hohe Standzeit besitzt und dabei kompakt gebaut ist.The object of the invention is therefore to provide a die for a tool set for mechanical joining according to the preamble of claim 1 to provide has a long service life and is compact in construction.

Diese Aufgabe wird gemäß dem kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved according to the characterizing part of claim 1.

Hierdurch wird eine Matrize für einen Werkzeugsatz zum mechanischen Fügen geschaffen, die den Matrizensegmenten jeweils eine Führungsbahn in der Matrizenhülse zuordnet. Die Matrizensegmente stützen sich bei ihrer radial zum Amboß gerichteten Verschiebung auf einer Stützfläche des Matrizengrundkörpers ab, und erhalten eine zusätzliche direkte Führung durch die Matrizensegmentabschnitte, die in die Matrizenhülse gleitbeweglich eingreifen. Eine solche Matrize ist hinsichtlich Matrizenhöhe und Matrizendurchmesser kompakt gebaut und weist verbesserte Führungseigenschaften für die verschiebbaren Matrizensegmente auf.As a result, a die for a tool set for mechanical joining created, the die segments each have a guideway in the Assigning template sleeve. The die segments are supported at their radially to Anvil directed displacement on a support surface of the Matrizengrundkörpers and receive an additional direct guide through the Die segment sections which slideably engage the die sleeve. Such a die is in terms of die height and die diameter built compact and has improved guiding properties for the sliding die segments on.

Die Matrizenhülse besitzt dazu vorzugsweise die Matrizenhülsenwand vollständig durchdringende Durchbrüche, in die die Matrizensegmente mit jeweils einem Fortsatz eingreifen. Der radiale Verschiebeweg der Matrizensegmente liegt innerhalb der Segmentführungen und führt somit zu keiner erhöhten Ausdehnung des Werkzeugs in radialer Richtung. Vorteilhaft ist darüberhinaus, daß Schmutz aus der Matrize ausgetragen werden kann, wodurch deren Standzeiten weiter verbessert werden.For this purpose, the die sleeve preferably has the die sleeve wall completely piercing breakthroughs, in which the die segments with one each Intervene extension. The radial displacement of the die segments lies within the segment guides and thus does not lead to increased expansion of the tool in the radial direction. It is also advantageous that dirt can be discharged from the die, which further their service life be improved.

Die Segmentführungen in der Matrizenhülse bilden geschlossene Führungen, die ein Gleiten der Matrizensegmente radial zum Amboß erlauben und zugleich ein axiales Verschieben derselben begrenzen. Die im Stand der Technik erforderlichen Hinterschneidungen an den Matrizensegmenten zur Sicherung derselben gegen axiales Verschieben von der Stützfläche können entfallen. Die Matrizensegmente und somit die gesamte Matrize kann folglich eine geringere axiale Bauhöhe besitzen. Das im Vergleich zum Stand der Technik verringerte Verhältnis von axialer zu radialer Erstreckung der Matrizensegmente führt dabei zugleich zu einer größeren Stabilität gegen Kippung während des radialen Verschiebens.The segment guides in the die sleeve form closed guides that allowing sliding of the die segments radially to the anvil and at the same time limit axial displacement of the same. The in the art required undercuts on the die segments for securing the same against axial displacement of the support surface can be omitted. The Matrizensegmente and thus the entire matrix can consequently a lesser have axial height. That reduced compared to the prior art Ratio of axial to radial extent of Matrizensegmente leads at the same time to a greater stability against tilting during the radial Shifting.

Bevorzugt ist die Matrize rund ausgebildet und besitzt eine Matrizenhülse mit in Umfangsrichtung sich erstreckende und auf einer Höhenlinie gegenüber der Stützfläche angeordnete Führungsbahnen. Die Matrizensegmente sind dann vorzugsweise als Ringteilstücke ausgebildet, wobei vorzugsweise mindestens drei Matrizensegmente vorgesehen sind. Besonders bevorzugt sind vier bis sechs Matrizensegmente vorgesehen, um eine möglichst geringe räumliche Ausdehnung von Trennfugen zwischen den Matrizensegmenten im gespreizten Zustand zu erreichen. Preferably, the die is round and has a die sleeve with in Circumferentially extending and on a contour line opposite the Support surface arranged guideways. The die segments are then preferably formed as annular sections, preferably at least three Matrizensegmente are provided. Particularly preferred are four to six Matrizensegmente provided to minimize the spatial extent of joints between the die segments in the expanded state to reach.

Bevorzugt wird die Federvorspannung durch einen elastischen Ring, der insbesondere eine Metallfeder sein kann, ausgeübt. Für eine sichere Aufnahme des elastischen Ringes können die Matrizensegmente jeweils eine in Umfangsrichtung verlaufende Nut aufweisen.Preferably, the spring bias is by an elastic ring, the in particular may be a metal spring exerted. For a safe recording of the elastic ring, the die segments each have a in Having circumferentially extending groove.

    Die Matrizensegmente 9, die entsprechend einer Teilung als Ringteilstücke ausgebildet sind, weisen jeweils eine innere gekrümmte Ringteilfläche 13 auf, die dem Amboß 3 zugewandt ist und im nicht gespreizten Zustand mit der Außenmantelfläche des Ambosses 3 in Anlage ist. Die Ringteilflächen 13 begrenzen den Hohlraum 2 am Amboß 3 und sind ausgebildet an einem dem Amboß 3 zugewandten Kopfstück 15 des Matrizensegmentes 9, an dem auch die Nut 6 für das Federelement 5 vorgesehen ist. Von dem Kopfstück 15 erstreckt sich der jeweilige Fortsatz 12 eines Matrizensegmentes 9. Während das Kopfstück 15 mit tortenstückartigen, also radial zum Amboß 3 verlaufenden, gegenüberliegenden seitlichen Randflächen 16 ausgebildet ist, besitzt der Fortsatz 12 parallel zum Amboßradius laufende, gegenüberliegende seitliche Randflächen 17, die bezogen auf die Umfangslinie der Stützfläche 4 auf Sekantenabschnitten liegen.The die segments 9, which according to a division as ring sections are formed, each having an inner curved annular surface 13, the the anvil 3 faces and in the non-splayed state with the Outer lateral surface of the anvil 3 is in abutment. The ring part surfaces 13 limit the cavity 2 on the anvil 3 and are formed on a the Anvil 3 facing head 15 of the die segment 9, on which also the Nut 6 is provided for the spring element 5. From the head 15 extends the respective extension 12 of a die segment 9. While the head piece 15th with cake-like, ie radially extending to the anvil 3, opposite lateral edge surfaces 16 is formed, has the extension 12 running parallel to the anvil radius, opposite lateral edge surfaces 17, based on the circumferential line of the support surface 4 on secant sections lie.

    Jedes Matrizensegment 9 aus Kopfstück 15 und Fortsatz 12 besitzt vorzugsweise eine ebene Bodenfläche 14 (vgl. Fig. 5), mit der das Matrizensegment 9 gleitverschieblich auf der Stützfläche 4 aufliegt und mit einem dem Amboß 3 abgewandten Fortsatz 12 in jeweils eine Segmentführung 10 hineinragt. Für einen Führungseingriff eines Matrizensegmentes 9 in der Matrizenhülse 8 greift der Fortsatz 12 des Matrizensegmentes 9 als Gleitstück in eine als geschlossene Führung ausgebildete Segmentführung 10 ein. Die Segmentführungen 10 durchdringen die Matrizenhülse 8 vollständig. Die Führungsbahnen 11 der Segmentführungen 10 und die Begrenzungsflächen der Fortsätze 12 sind nach Art von Gleitführungen aneinander angepaßt. Die Fortsätze 12 umfassen dazu neben der Bodenfläche 14 eine der Bodenfläche 14 gegenüberliegende oberseitige Führungsfläche 18. Die der Bodenfläche 14 eines Matrizensegmentes 9 zugewandte Fläche der Führungsbahn 11 bleibt vorzugsweise außer Eingriff mit dem Matrizensegment 9. Die Gleitbewegung des Matrizensegmentes 9 mit seiner Bodenfläche 14 von der Stützfläche 4 in die Matrizenhülse 8 erfolgt dann zuverlässig auf der Stützfläche 4.Each die segment 9 of header 15 and extension 12 preferably has a flat bottom surface 14 (see Fig. 5), with which the die segment 9 slidably rests on the support surface 4 and with an anvil. 3 remote projection 12 protrudes into a respective segment guide 10. For one Guiding engagement of a die segment 9 in the die sleeve 8 engages the Extension 12 of the die segment 9 as a slider in a closed Guide trained segment guide 10 a. The segment guides 10 penetrate the female sleeve 8 completely. The guideways 11 of Segment guides 10 and the boundary surfaces of the extensions 12 are according to Art matched by sliding guides. The extensions 12 include next to the bottom surface 14 of the bottom surface 14 opposite upper side Guide surface 18. The bottom surface 14 of a die segment 9 facing surface of the guideway 11 preferably remains out of engagement with the die segment 9. The sliding movement of the die segment 9 with his Bottom surface 14 of the support surface 4 in the die sleeve 8 then takes place reliable on the support surface 4.

    In dem in Fig. 5 dargestellten geschlossenen Zustand der Matrize 1 ragen die Fortsätze 12 der Matrizensegmente 9 mit einem Endstück bereits in die zugehörige Segmentführung 10, wodurch ein jedes Matrizensegment 9 in dieser Grundstellung fixiert geführt ist. Ein axiales Verschieben der Matrizensegmente 9 bei einem Auswärtsgleiten derselben wird damit von Anbeginn eng begrenzt. Die radiale Länge des Fortsatzes 12 gegenüber dem Kopfstück 15 ist ferner derart gewählt, daß die beweglichen Matrizensegmente 9 beim Spreizen durch die Matrizenhülse 8 nicht wegbegrenzt werden. Die Matrizensegmente 9 werden lediglich gegen die Federvorspannung des Federelementes 5 radial verschoben, das selbst mit Abstand zur Matrizenhülse 8 angordnet ist und deshalb auch keine Wegbegrenzung durch die Matrizenhülse 8 erfährt.In the closed state of the die 1 shown in Fig. 5 protrude the Extensions 12 of the die segments 9 with an end piece already in the associated segment guide 10, whereby each die segment 9 in this Basic position is guided. An axial displacement of the die segments 9 in an outward gliding of the same is thus limited from the beginning. The Radial length of the extension 12 relative to the head piece 15 is also such chosen that the movable die segments 9 during spreading through the Matrizenhülse 8 are not wegbegrenzt. The die segments 9 are only radially displaced against the spring bias of the spring element 5, which is even angordnet with distance to the female sleeve 8 and therefore no Wegbegrenzung through the die sleeve 8 undergoes.
