Description

Die Erfindung betrifft ein Verfahren und eine Anordnung zur Herstellung von offenen oder geschlossenen ringförmigen Konstruktionsbauteilen aus Leichtmetall und deren Legierungen, vorzugsweise aus Magnesium oder Magnesiumlegierungen, mit einer zwei- oder dreidimensionalen Struktur mittels Strangpressen.The invention relates to a method and an arrangement for producing open or closed ring-shaped structural components from light metal and their alloys, preferably from magnesium or magnesium alloys, with a two- or three-dimensional structure by means of extrusion.

Auf dem Gebiet des Automobilbaus ist das Space-Frame-Konzept bekannt. Bei dieser Karosseriebauart wird ein Skelett aus geschlossenen Hohlprofilen, die direkt oder über Knoten miteinander verbunden sind, verwendet. Durch den Einsatz von Aluminium- oder Magnesiummaterialien kann durch Gewichtseinsparung eine Verbrauchs- und Emissionsminderung erreicht werden.The space frame concept is known in the field of automobile construction. This type of body construction uses a skeleton made of closed hollow profiles that are connected to one another either directly or via nodes. By using aluminum or magnesium materials, consumption and emissions can be reduced by saving weight.

Die EP 0706843 B1 beschreibt ein Verfahren zur Herstellung von gekrümmten Hohlprofilen durch eine Kombination von Extrusion und Biegen sowie eine Vorrichtung zur Durchführung des Verfahrens, wobei das Hohlprofil mit oder unmittelbar nach dem formgebenden Strangpressvorgang durch eine quer zur Strangpresseinrichtung auf das Werkstück einwirkende Kraft gebogen wird. Die EP 0706843 B1 beschreibt gemäß der Erfindung ein beabsichtigtes Krümmen von Strangpressprofilen durch Runden ohne einen darauf folgenden Warmumformprozess.The EP 0706843 B1 describes a method for producing curved hollow profiles by a combination of extrusion and bending and a device for carrying out the method, the hollow profile being bent with or immediately after the shaping extrusion process by a force acting on the workpiece transversely to the extrusion device. The EP 0706843 B1 describes according to the invention an intentional bending of extruded profiles by rounding without a subsequent hot forming process.

Aus der US 5,305,625 ist ein Verfahren zum Strangpressen von gekrümmten Profilen bekannt, bei dem an der Innenfläche der Strangpressmatrize unterschiedliche Reibungswiderstände für eine lokale Verzögerung bzw. Beschleunigung des Fließvorgangs während des Strangpressens sorgen. Somit tritt aus der Matrize aufgrund unterschiedlicher Reibungsverhältnisse ein gekrümmtes Profil aus, das über eine gebogene Auslaufstrecke geführt wird, jedoch nicht weiter verformt wird.From the U.S. 5,305,625 a method for extrusion of curved profiles is known in which different frictional resistances on the inner surface of the extrusion die ensure a local delay or acceleration of the flow process during extrusion. Thus comes out of the die due to different Friction conditions from a curved profile that is guided over a curved outlet section, but is not further deformed.

Aus der JP-A-03 47615 ist ein Verfahren und eine Vorrichtung zur Herstellung gekrümmter Hohlprofile bekannt, bei dem während des Biegevorganges ein unter Druck stehendes Gas im Inneren des Hohlprofils eingeschlossen ist. In einer Entfernung zum Matrizenaustritt ist ein Führungsglied angeordnet, wobei durch die Bewegung des Führungsglieds quer zur Strangpressrichtung eine Krümmung des Hohlprofils erfolgt.From the JP-A-03 47615 a method and a device for producing curved hollow profiles are known in which a gas under pressure is enclosed in the interior of the hollow profile during the bending process. A guide member is arranged at a distance from the die outlet, the hollow profile being curved as a result of the movement of the guide member transversely to the extrusion direction.

Aus den bekannten Verfahren der direkten Rundung eines Strangpressprofils beim Austritt aus der Matrize durch Ausüben einer gesteuerten Querkraft zum Biegen eines Profils, bereitet die Erstellung einer erforderlichen Kontur besonders bei dreidimensionalen Profilen mit variabler Krümmung kaum überwindbare technische Schwierigkeiten.From the known method of direct rounding of an extruded profile when exiting the die by exerting a controlled transverse force to bend a profile, the creation of a required contour, especially for three-dimensional profiles with variable curvature, presents hardly any technical difficulties.

Um den technischen Anforderungen zu genügen wurde bereits vorgeschlagen, eine Kalibrierung der Kontur und des Querschnitts mittels Innenhochdruckumformung (IHU) des Strangpressprofils vorzunehmen. Nachteilig sind hierbei die enorm hohen Werkzeugkosten.In order to meet the technical requirements, it has already been proposed to calibrate the contour and cross section by means of hydroforming (hydroforming) of the extruded profile. The extremely high tool costs are a disadvantage here.

Weiterhin ist aus der DE 102 41 028 B3 , welche die Basis für den Oberbegriff des Anspruchs 4 bildet, ein Verfahren zur Herstellung von bogenförmigen (gerundeten) Strukturbauteilen aus einem Strangpressprofil, insbesondere aus Aluminium, Magnesium oder deren Legierungen, bekannt, welches nach dem Austreten aus der Matrize der Strangpresse zum Zwecke seiner Ausformung als gerades oder bogenförmiges (gerundetes) Profil von einem oder mehreren Führungswerkzeugen geführt wird, ein Endabschnitt mit einem Trennwerkzeug abgetrennt und im heißen Zustand mittels Greifwerkzeugen einem Warmumformprozess und einer oder mehreren Bearbeitungsstationen zugeführt wird, wobei vor dem Warmformprozess die Warmformtemperatur oder vor anderen Bearbeitungsstationen durch Kühlen des Werkstückes auf die optimale Prozesstemperatur eingestellt wird.Furthermore, from the DE 102 41 028 B3 , which forms the basis for the preamble of claim 4, a method for the production of curved (rounded) structural components from an extruded profile, in particular made of aluminum, magnesium or their alloys, known, which after exiting the die of the extrusion press for the purpose of its shaping is guided as a straight or curved (rounded) profile by one or more guide tools, an end section is cut off with a cutting tool and, in the hot state, is fed to a hot forming process and one or more processing stations by means of gripping tools, the thermoforming temperature prior to the warm forming process or cooling prior to other processing stations of the workpiece is set to the optimal process temperature.

Die JP S63 273571 A beschreibt die Herstellung von geschweißten Ringen. Das Verfahren beschreibt die Herstellung von geschweißten Ringen aus einem aufgecoilten Strangpreßprofil, wobei das Profil von einem Coil abgezogen wird und einer Spiralformmaschine zugeführt wird, um eine Spirale zu bilden. Nach dem Abschneiden der Spirale werden Flächen der geschnittenen Enden zusammengepresst und durch Stumpfschweißen miteinander verbunden. Es handelt sich hierbei um Ringe aus einem Vollmaterial.The JP S63 273571 A describes the manufacture of welded rings.

Die DE 103 17 080 A1 beschreibt ein Verfahren zur Herstellung von Blechformteilen aus Magnesium oder Magnesiumlegierungen, wobei ausgehend vom Gießprozess, die Blechformteile kontinuierlich durch Umformung hergestellt werden.The DE 103 17 080 A1 describes a method for the production of sheet metal parts from magnesium or magnesium alloys, starting from the casting process, the sheet metal parts are continuously produced by forming.

Die DE 26 11 200 A1 betrifft ein Verfahren und eine Vorrichtung zur Herstellung von Rohrbogenabschnitten. Im Anschluss an eine Strangpresse ist eine Strangpressform mit einem der Rohrkrümmung entsprechenden Preßkanal, in den sich ein analog gekrümmter und im wesentlichen dem Innendurchmesser des Rohrbogens entsprechender Kern befindet, vorgesehen, der Presskanal mit Kern außer in der Krümmungsebene noch in einer Zusatzebene so gewölbt ist, der ein Teil einer Wendel ist und die Windungen des austretenden wendelförmigen Strangpreß-Rohteils in Rohrbogensegmente, wie sie im Rohrleitungsbau in großen Mengen als Rohrbogen verwendet werden, zerteilt werden.The DE 26 11 200 A1 relates to a method and a device for the production of pipe bend sections. Following an extrusion press, an extrusion mold is provided with a press channel corresponding to the pipe curvature, in which there is an analogously curved core that essentially corresponds to the inside diameter of the pipe bend, the press channel with core is arched in an additional plane in addition to the plane of curvature, which is part of a helix and the turns of the exiting helical extruded raw part are divided into pipe bend segments, as used in large quantities as pipe bends in pipeline construction.

Die CA 9A- 1 078 153 A1 betrifft einen Haltering und ein Verfahren zur Herstellung desselben, wobei der Haltering einen T-förmigen Querschnitt aufweist. Das durch Strangpressen hergestellte einen T-förmigen Querschnitt aufweisende Profil wird mit Hilfe von Walzen in eine Spulenform gebracht und anschließend entlang einer Mantellinie der Spule durchtrennt. Die einzelnen Abschnitte der Spule werden dann zu Ringen weiterverarbeitet.The CA 9A- 1 078 153 A1 relates to a retaining ring and a method for producing the same, the retaining ring having a T-shaped cross section. The profile, which is produced by extrusion and has a T-shaped cross-section, is brought into a coil shape with the aid of rollers and then cut along a surface line of the coil. The individual sections of the coil are then processed into rings.

Ausgehend vom Stand der Technik besteht die Aufgabe der Erfindung darin, ein verbessertes Verfahren zur Herstellung von offenen oder geschlossenen ringförmigen Konstruktionsbauteilen, mit einer beliebigen annähernd mehreckigen Form mit in den Eckbereichen vorgesehenen radienförmigen Abschnitten, insbesondere für Kraftfahrzeuge, aus Leichtmetall und deren Legierungen mit einer zwei- oder dreidimensionalen Struktur anzugeben, bei welchen ausgehend vom Strangpressprozess Konstruktionsbauteile mit besonders hoher Genauigkeit hinsichtlich ihrer Maßgenauigkeit und ihrer Formtreue herstellbar sind.Based on the prior art, the object of the invention is to provide an improved method for the production of open or closed ring-shaped structural components, with any approximately polygonal shape in the Radial sections provided in the corner areas, in particular for motor vehicles, made of light metal and their alloys with a two- or three-dimensional structure, in which, starting from the extrusion process, structural components can be produced with particularly high accuracy in terms of their dimensional accuracy and their dimensional accuracy.

Eine weitere Aufgabe besteht darin, eine Anordnung zur Durchführung des Verfahrens anzugeben, um ein ringförmiges Konstruktionsbauteil als einbaufertige Komponente herzustellen.Another object is to provide an arrangement for carrying out the method in order to produce an annular structural component as a component that is ready for installation.

Erfindungsgemäß wird die Aufgabe durch ein Verfahren und eine Anordnung gemäß den Ansprüchen 1 und 4 gelöst. In den Unteransprüchen sind weitere vorteilhafte Ausgestaltungen der Erfindung angegeben.According to the invention, the object is achieved by a method and an arrangement according to claims 1 and 4. Further advantageous configurations of the invention are specified in the subclaims.

Das Verfahren zur Herstellung von offenen oder geschlossenen ringförmigen Konstruktionsbauteilen aus Leichtmetall und deren Legierungen, vorzugsweise aus Magnesium oder einer Magnesiumlegierung, mit einer zwei- oder dreidimensionalen Struktur umfasst die Schritte - Herstellen eines ringförmigen Konstruktionsbauteiles aus einem aus der Strangpresse austretenden Strangpressprofils in einer Helixform, wobei sich die Enden geringfügig überlappen, - Trennen der Helixform vom Pressstrang an der Stelle der Überlappung, - Kalibrieren der aus dem Strangpressprofil hergestellten Helixform zu einem zwei- oder dreidimensionalen Konstruktionsbauteil.The method for the production of open or closed ring-shaped structural components made of light metal and their alloys, preferably made of magnesium or a magnesium alloy, with a two- or three-dimensional structure comprises the following steps - production of an annular structural component from an extruded profile emerging from the extrusion press in a helical shape, whereby the ends overlap slightly, - separation of the helical shape from the extruded strand at the point of overlap, - calibration of the helical shape made from the extruded profile to form a two- or three-dimensional structural component.

Um ein geschlossenes ringförmiges Konstruktionsbauteil zu erhalten, werden die nach dem Kalibrieren in einer Ebene liegenden Enden mittels einer unlösbaren Verbindung miteinander verbunden. Dies kann beispielsweise durch Schweißen oder Kleben erfolgen.In order to obtain a closed, ring-shaped structural component, the ends lying in one plane after the calibration are connected to one another by means of a permanent connection. This can be done for example by welding or gluing.

Erfindungsgemäß wird das ringförmige Konstruktionsbauteil in Kreisform oder in beliebiger annähernd mehreckiger Form ausgebildet, wobei in den Eckbereichen vorgesehene Radien konstant oder zu- oder abnehmend ausgeführt sein können.According to the invention, the ring-shaped structural component is designed in a circular shape or in any approximately polygonal shape, with the radii provided in the corner regions being able to be designed to be constant or increasing or decreasing.

Die zur Durchführung des Verfahrens eingesetzte Anordnung besteht im Wesentlichen aus einem Blocklager, einem Blockerwärmungsofen, einer Strangpresse mit Führungswerkzeugen zur Erzeugung einer Helixform, einer Trenneinrichtung, einer Kalibriereinrichtung und gegebenenfalls einer Einrichtung zum unlösbaren Verbinden der Enden des ringförmigen Konstruktionsbauteils.The arrangement used to carry out the method essentially consists of a block storage, a block heating furnace, an extruder with guide tools for creating a helical shape, a separating device, a calibration device and, if necessary, a device for permanently connecting the ends of the annular structural component.

Erfindungsgemäß ist die Kalibriereinrichtung als Biege- und/oder Richteinrichtung ausgebildet. Mittels der Kalibriereinrichtung werden die Helixformen zu einem zwei- oder dreidimensionalen Konstruktionsbauteil verformt. Die Kalibriereinrichtung besteht aus einem zweigeteilten Kalibrierwerkzeug, dessen obere und / oder untere Hälften zueinander verfahrbar sind. Durch Druckbeaufschlagung mindestens einer der beiden Werkzeughälften über mindestens einen Presszylinder werden die Konstruktionsbauteile kalibriert und zwar auf ein einheitliches Maß bzw. auf eine einheitliche Form. Gleichzeitig werden die Konstruktionsbauteile gerichtet. Je nach Ausführung der Werkzeughälften der Kalibriereinrichtung können die Konstruktionsbauteile in eine zwei- oder dreidimensionale Form gebracht werden.According to the invention, the calibration device is designed as a bending and / or straightening device. By means of the calibration device, the helical shapes are deformed into a two- or three-dimensional structural component. The calibration device consists of a two-part calibration tool whose upper and / or lower halves can be moved relative to one another. By applying pressure to at least one of the two tool halves via at least one press cylinder, the structural components are calibrated to a uniform size or a uniform shape. At the same time, the structural components are straightened. Depending on the design of the tool halves of the calibration device, the structural components can be brought into a two- or three-dimensional shape.

Erfindungsgemäß sind in eine oder beide Werkzeughälften Prägematrizen, Schnitt- oder Lochwerkzeuge integriert, wodurch die Möglichkeit besteht, während des Kalibriervorgangs Prägeoperationen in den Oberflächen und / oder Schnitt- und / oder Lochoperationen vorzunehmen.According to the invention, embossing dies, cutting or punching tools are integrated into one or both tool halves, which makes it possible to carry out embossing operations in the surfaces and / or cutting and / or punching operations during the calibration process.

Ein Vorteil der Erfindung besteht darin, dass während des Fertigungsvorganges, ausgehend vom Strangpressen bis zum Kalibrieren, die Warmformung abläuft und die Warmumformtemperatur je nach verwendetem Leichtmetall im Bereich von 150°C bis 600°C liegt.One advantage of the invention is that the hot forming takes place during the manufacturing process, starting from the extrusion to the calibration, and the hot forming temperature is in the range of 150 ° C to 600 ° C depending on the light metal used.

Bei Verwendung von Magnesium bzw. einer Magnesiumlegierung liegt die Warmumformtemperatur im Bereich von 250°C bis 450°C.When using magnesium or a magnesium alloy, the hot forming temperature is in the range from 250 ° C to 450 ° C.

Anhand eines Ausführungsbeispiels soll die Erfindung näher beschrieben werden. Die dazugehörige Figur 1 zeigt die Anordnung zur Herstellung eines geschlossenen ringförmigen Konstruktionsbauteils.The invention is to be described in more detail using an exemplary embodiment. The Associated Figure 1 shows the arrangement for producing a closed ring-shaped structural component.

Die Anlage gemäß Figur 1 besteht aus dem Blocklager 1 zur Vorratslagerung des Pressbolzen 4, dem Erwärmungsofen 2, in dem die Pressbolzen 4 auf die Strangpresstemperatur erwärmt werden, sowie der Strangpresse 3 mit den Führungswerkzeugen 5 zur Erzeugung einer Helixform 9. Daran schließt sich eine Kalibriereinrichtung 7 und eine Verbindungseinrichtung 8, in der die kalibrierten Enden der Helixform 9 zu einem geschlossenen ringförmigen Konstruktionsbauteil 10 verbunden werden.The plant according to Figure 1 consists of the block storage 1 for stock storage of the billets 4, the heating furnace 2, in which the billets are heated 4 on the extrusion temperature, and the extruder 3 with the guide tools 5 9 for generating a helix shape This is followed by a calibration device 7 and a connector 8 , in which the calibrated ends of the helix shape 9 are connected to form a closed, annular structural component 10 .

Die auf Presstemperatur erwärmten Pressbolzen 4 werden in den Rezipienten der Strangpresse 3 eingesetzt und zu einem Strangpressprofil umgeformt. Das aus der Matrize der Strangpresse 3 austretende Strangpressprofil wird dann mittels der Führungswerkzeuge 5 zu einer Helixform 9 umgeformt und zwar derart, dass sich die Enden der Helixform 9 geringfügig überlappen.The extrusion billets 4 heated to the extrusion temperature are inserted into the recipient of the extrusion press 3 and formed into an extruded profile. The extruded profile emerging from the die of the extrusion press 3 is then formed into a helix shape 9 by means of the guide tools 5 in such a way that the ends of the helix shape 9 overlap slightly.

Anschließend wird die Strangpresse 3 gestoppt und die Helixform 9 an der Stelle der überlappenden Enden mittels einer Trenneinrichtung 6, die als fliegende Säge ausgebildet ist, vom austretenden Strangpressprofil getrennt. Im Anschluss an den Trennvorgang wird die abgetrennte Helixform 9 einer Kalibriereinrichtung 7 übergeben und in dieser beispielsweise zu einem ringförmigen Konstruktionsbauteil 10 kalibriert. Durch die Kalibriereinrichtung 7 erfolgt die Erstellung eines Konstruktionsbauteils 10 mit einer hohen Maßgenauigkeit und Formtreue, und zwar als einbaufertige Komponente.The extruder 3 is then stopped and the helical shape 9 is separated from the exiting extruded profile at the location of the overlapping ends by means of a separating device 6, which is designed as a flying saw. Following the cutting process, the separated helical shape 9 is transferred to a calibration device 7 and is calibrated in this, for example, to form an annular structural component 10 . The calibration device 7 creates a structural component 10 with a high degree of dimensional accuracy and dimensional accuracy, specifically as a ready-to-install component.

Im Anschluss an den Kalibriervorgang werden die Enden durch eine unlösbare Verbindung, beispielsweise durch Schweißen, in der Verbindungsrichtung 8 verbunden. Somit verlässt eine einbaufertige Komponente die Anlage.Following the calibration process, the ends are connected in the connection direction 8 by a permanent connection, for example by welding. A ready-to-install component thus leaves the system.
