Abstract

The die has a jacket shell (3) of rectangular cross section, is open at the top and can be fixed to a base body (1). The die segments (2, 2a) can be moved and guided in parallel guide slots (8, 8', 8a, 8a') in the jacket shell. There are projecting guide devices (5, 5a) on the sides of the die segments to engage positively in the guide slots.

Description

Die Erfindung betrifft eine Matrize für einen aus einem Stempel und einer Matrize bestehenden Werkzeugsatz zum mechanischen Fügen flächig aufeinander liegender Bleche durch Umformung, mit einem Amboss und Matrizensegmenten, die zusammen mit dem Amboss einen Hohlraum ausbilden, in den hineingefügt wird, und die im Winkel quer, vorzugsweise orthogonal zur Hohlraumachse gegen eine Federkraft verschiebbar gelagert sind, und mit einer die Matrizensegmente umgebenen Mantelhülse. Die Spreizbewegung erfolgt vorzugsweise orthogonal zur Hohlraumachse H, sie kann aber auch nach oben oder unten quergerichtet erfolgen.The invention relates to a die for a tool set consisting of a punch and a die for the mechanical joining of sheet metal lying on one another by forming, with an anvil and die segments, which together with the anvil form a cavity into which is inserted and which are transverse in angle , Preferably orthogonal to the cavity axis are slidably mounted against a spring force, and with a surrounding the Matrizensegmente jacket sleeve. The spreading movement is preferably orthogonal to the cavity axis H, but it can also be made transversely upwards or downwards.

Eine solche Matrize ist beispielsweise aus der EP 1 468 758 A1 bekannt. Um zwei aufeinander liegende Bleche durch Umformung zu verbinden, werden diese überlappt zwischen den Stempel und die Matrize gelegt. Der Stempel wird auf die Bleche herabgefahren und aufgedrückt und drückt das Material in die Matrize bzw. in den durch die Matrizensegmente und den Amboss gebildeten Hohlraum. Beim Umformen müssen sich die Matrizensegmente dann verschieben, um den Hohlraum zu vergrößern, damit das verdrängte Material aufgenommen werden kann.Such a template is for example from the EP 1 468 758 A1 known. In order to connect two superimposed sheets by forming, they are overlapped between the punch and the die placed. The punch is moved down onto the plates and pressed and pushes the material into the die or in the cavity formed by the die segments and the anvil. When forming, the die segments must then move to increase the cavity so that the displaced material can be absorbed.

Die bekannte Matrize ist rund ausgebildet. Der Amboss ist in die Matrizenhülse eingepresst. An dem Amboss liegen sechs kreissegmentförmig ausgebildete Matrizensegmente an, die jeweils radial außen über einen Fortsatz in radialen Umfangsschlitzen in der Matrizenhülse geführt sind. Um auf die Matrizensegmente in radialer Richtung eine Federvorspannung aufbringen zu können, sind diese über einen einzigen Federring (O-Ring) verbunden. Nach dem Fügen werden die Matrizensegmente mittels der Kraft des Federringes in ihre Ursprungslage zurückgezogen.The known die is round. The anvil is pressed into the die sleeve. At the anvil are six circular segment-shaped die segments, which are each guided radially outwardly via an extension in radial circumferential slots in the die sleeve. In order to be able to apply a spring preload to the die segments in the radial direction, they are connected via a single spring ring (O-ring). After joining, the die segments are pulled back into their original position by means of the force of the spring ring.

Die Matrizensegmente gleiten bei der Ausweichbewegung mit ihrer vollen Unterseite auf der ringförmigen Stützfläche des Ambosses. Um eine ausreichende Rückstellkraft aufbringen zu können, muss der Federring folglich entsprechend groß dimensioniert sein, was den Außenumfang der Matrize mitbestimmt. Kompliziert geformte Blechteile, die miteinander verbunden werden sollen, stellen an den Fügestellen teilweise nicht genügend Freiraum zur Verfügung, um eine runde Matrize einsetzen zu können. Zudem kann die bekannte Matrize nicht eingesetzt werden, wenn der Spreizweg der Matrizensegmente begrenzt werden muss.The Matrizensegmente slide in the evasive movement with its full bottom on the annular support surface of the anvil. In order to apply sufficient restoring force, the spring ring must consequently be dimensioned correspondingly large, which co-determines the outer circumference of the die. Complicatedly shaped sheet metal parts that are to be connected to one another do not provide sufficient space at the joints in order to be able to use a round die. In addition, the known die can not be used if the Spreizweg the die segments must be limited.

Aus der EP 0 835 701 A2 ist eine Durchsetzfügematrize bekannt, die eine rechteckige Außenkontur aufweist. Der Amboss dieser Matrize ist an einem Grundkörper ausgebildet. Es sind zwei gegenüberliegend angeordnete Matrizensegmente vorgesehen. Auf den Grundkörper ist eine Matrizenhülse aufgesetzt, die über ihrem Umfang im Wesentlichen geschlossen ist und nach oben nur eine runde Ausnehmung aufweist, durch die der vorstehende Teil der Matrizensegmente hindurchragt. Die geschlossene Matrizenhülse führt die Matrizensegmente und sichert sie gegen Herausfallen. Die Rückstellkraft für die Federsegmente wird durch einstückig mit der Matrizenhülse ausgebildete Federlaschen aufgebracht, die durch doppelte Abkantungen ausgebildet werden. Damit die Federlaschen ihre Funktion erfüllen können, muss die gesamte Matrizenhülse aus Federstahl mit einer, wegen der Federwirkung nach oben begrenzten Federstahldicke ausgebildet werden. Dies hat den Nachteil, dass die Matrizenhülse nicht in der Lage ist, hohe Stützkräfte aufzunehmen, die notwendig sind, wenn die zu fügenden Bauteile an der Matrizenhülse anstoßen. Um zu vermeiden, dass in einem solchen Fall die Matrize zerstört wird und Bruchstücke umherfliegen, muss ein stabiler Matrizenschutz um die Matrize herumpositioniert werden, der die Arbeitsbreite, u. U. auch die Arbeitsdicke der Matrize vergrößert, so dass diese, wenn nur ein begrenzter Bauteilfreiraum zur Verfügung steht, dann ebenso wenig wie eine runde Matrize eingesetzt werden kann. Darüber hinaus hat diese Matrize den Nachteil, dass durch die umfangsseitig im Wesentlichen verschlossene Matrizenhülse die Reinigung erschwert wird und teilweise eine Reinigung nur durch zeitaufwändiges Zerlegen der Matrize möglich ist.From the EP 0 835 701 A2 is a push-through matrix known, which has a rectangular outer contour. The anvil of this die is formed on a base body. There are two oppositely arranged die segments provided. On the main body a die sleeve is placed, which is substantially closed over its circumference and has upwards only a circular recess through which protrudes the projecting part of the die segments. The closed die sleeve guides the die segments and secures them from falling out. The restoring force for the spring segments is applied by integrally formed with the die sleeve spring tabs, which are formed by double folds. So that the spring tabs can fulfill their function, the entire die sleeve must be made of spring steel with a, due to the spring effect upwardly limited spring steel thickness. This has the disadvantage that the die sleeve is not able to absorb high supporting forces, which are necessary when the components to be joined abut the die sleeve. In order to avoid that in such a case the die is destroyed and fragments fly around, a stable die protection must be placed around the die, which the working width, u. U. also increases the working thickness of the die, so that if only a limited component space is available, then as little as a round die can be used. In addition, this die has the disadvantage that the cleaning is made difficult by the circumferentially substantially closed die sleeve and sometimes a cleaning is only possible by time-consuming disassembly of the die.

Aus der WO 03/084694 A1 ist ein Werkzeug zur Herstellung einer Durchsetzfügeverbindung bekannt, bei dem die Wandabschnitte der Arbeitsöffnung der Matrize nachgiebig gestaltet sind und zur Erzielung einer Kaltverhärtung des verquetschten Materials nach Zurücklegung einer bestimmten Strecke über einen Anschlag gestoppt werden.From the WO 03/084694 A1 a tool for producing a clinching compound is known, in which the wall sections of the working opening of the die are made resilient and are stopped to achieve a cold hardening of the squeezed material after covering a certain distance via a stop.

Die EP 0 799 843 B1 offenbart ein Werkzeug zur Herstellung von Fügestellen zwischen plattenförmigen Teilen, das ein oberes Werkzeugteil mit einem Stempel und einem seitlich drückenden Element und ein unteres Werkzeugteil aufweist, das mit einer Matrize versehen ist. Stempel und Matrize wirken derart zusammen, dass das Material in den Platten unter Ausbildung eines Holraumes in den Platten und seitlichem Ausdehnen des unteren Teiles des Holraumes gezogen wird, um die Teile miteinander zu fügen. Um ein kompaktes Werkzeug mit geringen Abmessungen zu erhalten ist vorgesehen, dass die Matrize mindestens zwei Matrizenteile aufweist, die um den Gegenstempel herum angeordnet sind.The EP 0 799 843 B1 discloses a tool for manufacturing joints between plate-shaped parts, which has an upper tool part with a punch and a side-pressing element and a lower tool part, which is provided with a die. The punch and die cooperate to draw the material in the plates to form a hollow space in the plates and to laterally expand the lower portion of the cavity to join the parts together. In order to obtain a compact tool with small dimensions, it is provided that the die has at least two die parts which are arranged around the counter punch.

Von dieser Problemstellung ausgehend, soll die eingangs beschriebene Matrize so verbessert werden, dass sie bei gleich bleibender Stabilität kleiner ausgebildet werden kann, um auch an kompliziert erreichbaren Bauteilstellen eingesetzt werden zu können.Starting from this problem, the template described above is to be improved so that it can be made smaller while maintaining the same stability in order to be able to be used even at complex achievable parts points.

Zur Problemlösung zeichnet sich eine gattungsgemäße Matrize dadurch aus, dass

  1. a) die Mantelhülse im Querschnitt im Wesentlichen rechteckig, nach oben offen und am Grundkörper befestigbar ist,
  2. b) die Matrizensegmente sind in sich parallel gegenüber liegenden Führungsschlitzen in der Mantelhülse lagerbar und führbar,
  3. c) seitlich an den Matrizensegmenten hervorstehende Führungsmittel zum formschlüssigen Eingriff in die Führungsschlitze vorhanden sind.
To solve the problem, a generic die is characterized in that
  1. a) the jacket sleeve in cross-section is substantially rectangular, open at the top and attachable to the base body,
  2. b) the die segments are storable and feasible in parallel guide slots in the jacket sleeve,
  3. c) on the side of the die segments projecting guide means for positive engagement in the guide slots are present.

Durch die rechteckige Ausgestaltung der Mantelhülse kann die Matrize in einer Orientierung (Richtung) sehr schmal ausgebildet werden. Weil die Matrizenelemente in sich parallel gegenüberliegenden Führungsschlitzen in der Mantelhülse gelagert und geführt sind, sind Berührungsflächen in den Lagerstellen klein, so dass nur geringe Reibungskräfte auftreten und somit entsprechend geringe Rückstellkräfte notwendig sind. Gleichzeitig sichern die Führungsschlitze die Matrizenelemente auch gegen Herausfallen. Die Mantelhülse kann also nach oben offen ausgebildet sein, so dass sich festsetzende Verschmutzungen leicht entfernt werden können.Due to the rectangular configuration of the jacket sleeve, the die in an orientation (direction) can be made very narrow. Because the die elements are mounted and guided in parallel opposite guide slots in the jacket sleeve, contact surfaces in the bearings are small, so that only low frictional forces occur and thus correspondingly low restoring forces are necessary. At the same time, the guide slots also secure the die elements against falling out. The jacket sleeve can thus be designed to be open at the top, so that settling contaminants can be easily removed.

Dadurch, dass die jedem Matrizensegment zugeordnete Feder ausschließlich die Federfunktion zu erfüllen hat, kann durch eine geeignete Werkstoff- und Werkstoffdickenauswahl die notwendige Federkraft vorgegeben werden.Due to the fact that the spring associated with each die segment has to fulfill only the spring function, the necessary spring force can be predetermined by a suitable material and material thickness selection.

Wenn nur zwei sich gegenüberliegende Matrizensegmente verwendet werden, kann die Außenkontur schmal gehalten werden.If only two opposing die segments are used, the outer contour can be kept narrow.

Die Federn sind insbesondere vorzugsweise als Blattfedern ausgebildet, wodurch der Bauraum in Längsrichtung der Matrize klein gehalten werden kann. Die Federn werden vorzugsweise über in den Grundkörper einpressbare Bolzen befestigt. Mittels dieser Bolzen kann auch die Mantelhülse am Grundkörper befestigt werden.The springs are in particular preferably designed as leaf springs, whereby the space in the longitudinal direction of the die can be kept small. The springs are preferably fastened via bolts which can be pressed into the base body. By means of these bolts and the jacket sleeve can be attached to the body.

Die Führung der Matrizensegmente in den Führungsschlitzen kann über je einen einpressbaren Bolzen erfolgen oder über Führungsnasen, die seitlich von den Matrizensegmenten abstehen.The leadership of the die segments in the guide slots can be done via a respective einpressbaren bolt or guide lugs which protrude laterally from the die segments.

Um die Führungsbolzen einpressen zu können, sind die Matrizensegmente an ihren seitlichen, äußeren Enden mit einer Durchgangsbohrung versehen.In order to press in the guide pins, the die segments are provided at their lateral, outer ends with a through hole.

Wenn der Werkstoff für die Mantelhülse von hoher Festigkeit ist, kann die Mantelhülse auch als Anschlag zur Spreizwegbegrenzung für die Matrizensegmente und/oder als zusätzliche Stütze für die aufliegenden Bauteile dienen.If the material for the jacket sleeve is of high strength, the jacket sleeve can also serve as a stop for Spreizwegbegrenzung for the die segments and / or as an additional support for the overlying components.

Mit Hilfe einer Zeichnung sollen Ausführungsbeispiele der Erfindung nachfolgend erläutert werden:With the help of a drawing, embodiments of the invention are explained below:

Die Matrize besteht im Wesentlichen aus dem Grundkörper 1 mit dem daran ausgebildeten Amboss 7, der Mantelhülse 3 und den beiden Matrizensegmenten 2, 2a. Die Matrizensegmente 2, 2a bilden zusammen mit dem Amboss 7 einen Hohlraum mit der Hohlraumachse H, zu der sie quer verschiebbar in der Mantelhülse 3 gelagert sind. Der Verschiebeweg kann orthogonal zur Hohlraumachse H sein oder in einem aufwärts bzw. abwärts gerichteten Winkel.The die essentially consists of the main body 1 with the anvil 7 formed thereon, the jacket sleeve 3 and the two die segments 2, 2a. The die segments 2, 2 a together with the anvil 7 form a cavity with the cavity axis H, to which they are mounted transversely displaceably in the jacket sleeve 3. The displacement may be orthogonal to the cavity axis H or at an upward or downward angle.

Im Grundkörper 4 sind zwei Blattfedern 4, 4a seitlich befestigt, die eine Vorspannkraft auf die Matrizensegmente 2, 2a ausüben und die Rückstellkraft aufbringen, um nach dem Fügen die Matrizensegmente 2, 2a in ihre Ausgangslage zurückzubringen. Die Matrizensegmente 2, 2a sind an ihren seitlichen, äußeren Enden mit je einer Durchgangsbohrung 10, 10a versehen, in die Bolzen 5, 5a eingesteckt werden können, die dann in den in der Mantelhülse 3 vorgesehenen Führungsschlitzen 8, 8'; 8a, 8a' formschlüssig aufgenommen werden, wodurch die die Spreizbewegung ausführenden Matrizensegmente geführt werden. Die Bolzen 5, 5a sichern zusammen mit den Führungsschlitzen 8, 8'; 8a, 8a' die Matrizensegmente 2, 2a gegen Herausfallen.In the main body 4, two leaf springs 4, 4a are laterally attached, which exert a biasing force on the die segments 2, 2a and apply the restoring force to bring back after fitting the Matrizensegmente 2, 2a in their initial position. The die segments 2, 2a are provided at their lateral, outer ends, each with a through hole 10, 10a, into which bolts 5, 5a can be inserted, which are then inserted into the guide slots 8, 8 'provided in the jacket sleeve 3; 8a, 8a 'are received positively, whereby the spreading movement exporting die segments are performed. The bolts 5, 5a secure together with the guide slots 8, 8 '; 8a, 8a 'the die segments 2, 2a against falling out.

Die Mantelhülse 3 ist nur seitlich geschlossen. Oben und unten ist sie offen.The jacket sleeve 3 is closed only laterally. It is open at the top and bottom.

Die Blattfedern 4, 4a, die an der Rückseite der Matrizensegmente 2, 2a anliegen, werden über in den Grundkörper 1 einschlagbare Bolzen 6, 6a im Grundkörper 1 fixiert. Über die Bolzen 6, 6a wird gleichzeitig auch die Mantelhülse 3 am Grundkörper 1 befestigt. Wird die Werkstoffauswahl für die Mantelhülse 3 entsprechend hochwertig getroffen, kann die Innenwandung der Mantelhülse 3 als Spreizweg begrenzender Anschlag für die Matrizensegmente 2, 2a und/oder als zusätzliche Stütze für aufliegende Bauteile dienen.The leaf springs 4, 4a, which bear against the rear side of the die segments 2, 2a, are fixed in the base body 1 by means of bolts 6, 6a which can be driven into the base body 1. At the same time, the jacket sleeve 3 is fastened to the base body 1 via the bolts 6, 6a. If the choice of material for the casing sleeve 3 met with high quality, the inner wall of the casing sleeve 3 as Spreizweg limiting Stop for the die segments 2, 2a and / or serve as additional support for resting components.

Wie Figur 2 zeigt, können zur Führung der Matrizensegmente 2, 2a in den Führungsschlitzen 8, 8'; 8a, 8a' der Mantelhülse 3 den Matrizensegmenten 2, 2a auch seitlich hervorstehende Nasen 9, 9a ausgebildet sein, die einstückig mit den Matrizensegmenten 2, 2a ausgebildet sind. Auch ist es denkbar, anstelle einteilig ausgebildeter Nasen 9, 9a, vier Bolzen vorzusehen, die in entsprechende seitlich in den Matrizensegmenten 2, 2a vorgesehene Bohrungen eingesetzt, bzw. eingepresst werden.As FIG. 2 shows, for guiding the die segments 2, 2a in the guide slots 8, 8 '; 8a, 8a 'of the jacket sleeve 3 the die segments 2, 2a and laterally projecting lugs 9, 9a may be formed, which are integrally formed with the die segments 2, 2a. It is also conceivable, instead of integrally formed lugs 9, 9a, to provide four bolts which are inserted into corresponding holes provided laterally in the die segments 2, 2a, or pressed in.
