Exemplary of other prior art inventive solution descriptions are in
  • WO 2012/055688 A1
    a method and an apparatus for producing only one of the shaped magnesium sheet parts described.
    The system consists of a coolable forming tool with punch and die, wherein the magnesium sheet parts are removed with a gripping device individually from a separately arranged parts heating device and inserted into this single tool. After molding, the magnesium sheet part is removed from the forming tool with a second gripping device and stacked.
  • DD 202 403 A
    includes a device for heated production of sheet metal parts from sheet-metal strips, wherein the forming tool consists of several individual tools. It is also coolable. The parts-heating device is arranged like a bridge over the metal bands and separately at a distance in front of the forming tool.
  • DE 101 28 199 B4
    includes a device for forming magnesium sheets, wherein a buckle by means of two rounding and a fold is incorporated into a metal sheet with a single tool. The partial heater is a gas heater wherein the gas flames act on and contact the active surfaces of the single tool and the magnesium sheet deformation surfaces.
  • DE 10 2011 051 943 A1 .
  • DE 10 2010 005 263 A1 and
  • DE 10 2009 000 981 T5
    also include molds with which the processing of heated sheet metal blanks and boards made of high-strength aluminum is feasible.
    For technical reasons, however, these tools only have processing stations and forming stations, each with a production level. Thus, these training in an individual, multi-stage cutting and molding production can not be used.

Nachteilig ist an diesen erfinderischen Lösungen, dass

  • die Erwärmungsvorrichtung zur Erwärmung von Blechteilen und Platinen in der Ausbildung als Blechbänder oder als zugeschnittene Blechtafeln und Platinen separiert von dem Bearbeitungswerkzeug zur Teileherstellung angeordnet sind und damit eine verfahrensbehindernde Abkühlung bereits vor der ersten Bearbeitung erfolgt,
  • an den Einzelwerkzeugen in dem Bearbeitungswerkzeug keine Nacherwärmung oder temperaturkonstanthaltende Aufheizung der Aktivflächen durchführbar ist, so dass an den Schnitt- und Formflächen optische und technologische Funktions- und Qualitätsmängel entstehen können,
  • bei Erwärmung der Magnesiumblech-Teilen mittels Gasheizungen durch die unmittelbare Flammeneinwirkung auf die Schnitt- und Formflächen ebenfalls optische und technologische Qualitätsmängel feststellbar sein werden und dass
  • diese bekannten Verfahren und Werkzeugkonstruktionen keine industrielle Herstellung mit großer Fertigungstiefe in Folgeverbundwerkzeugen und Transferwerkzeugen mit einer großen Anzahl von Verfahrensschritten zum Schneiden, Formen und Ausschneiden in Einzelwerkzeugstufen nicht erlauben, da sie jeweils für nur eine Fertigungsstufe konzipiert sind.
A disadvantage of these inventive solutions that
  • the heating device for heating sheet metal parts and blanks in the form of metal strips or cut sheet metal plates and blanks separated from the machining tool for parts production are arranged and thus a process-hindering cooling takes place even before the first processing,
  • no reheating or constant temperature heating of the active surfaces can be carried out on the individual tools in the processing tool so that optical and technological defects in function and quality can arise at the cutting and shaping surfaces,
  • When heating the magnesium sheet parts by means of gas heaters by the direct action of flame on the cutting and shaping surfaces also optical and technological quality defects will be detectable and that
  • These known methods and tool designs do not allow industrial production with large vertical integration in progressive tools and transfer tools with a large number of process steps for cutting, forming and cutting in individual tool stages, since they are each designed for only one manufacturing stage.

Der im Patentanspruch 1 angegebenen Erfindung liegt deshalb die Problemstellung zu Grunde, dass Verfahren zur Herstellung von Blechteilen aus Magnesium- und hochfestem Aluminium so auszubilden, dass

  • nach einer grundhaften Erwärmung von Blechband oder Platinen verfahrensbehindernde Abkühlungen oder Zwischenabkühlungen von der ersten Bearbeitung vermieden werden,
  • ergänzende Erwärmungen an den Einzelwerkzeugstufen zum Ausgleich von Temperaturverlusten und zur Konstanthaltung der nominellen Arbeitstemperatur ermöglicht werden,
  • optische und technologische Qualitätsmängel an den Aktivflächen der Einzelwerkzeugstufen und an den Schnitt- und Formflächen der Blechteile aus Magnesium- und hochfesten Aluminiumteile ausgeschlossen sind,
  • ein industrielles Herstellungsverfahren mit großer Fertigungstiefe in einem laufenden Prozess realisierbar ist,
    und dass
  • die Anwendungsvorteile von Blechteilen aus Magnesium und aus hochfesten Aluminiumteilen im Automobilbau und in anderen Produktherstellungsbereichen bezogen auf Leichtgewichtigkeit, Kostenminimierung und Qualität voll zum tragen kommen.
The indicated in claim 1 invention is therefore based on the problem that the method for the production of sheet metal parts of magnesium and high-strength aluminum in such a way that
  • avoid process-slowing cooling or intermediate cooling of the first processing after a thorough heating of sheet metal strip or blanks,
  • supplemental heating at the individual tool stages to compensate for temperature losses and to keep the nominal working temperature constant,
  • optical and technological quality defects on the active surfaces of the individual tool steps and on the cutting and forming surfaces of the sheet metal parts of magnesium and high-strength aluminum parts are excluded,
  • an industrial production process with large vertical range of manufacture can be realized in a running process,
    and that
  • The application advantages of sheet metal parts made of magnesium and high-strength aluminum parts in the automotive industry and in other product manufacturing areas based on lightweight, cost minimization and quality come to fruition.

Diese Problemstellung wird durch den Patentanspruch 1, und ergänzt durch die Patentansprüche 2 und 3, wie folgt gelöst:

  • Alle für die qualitative Herstellung von Blechteilen aus Magnesium und aus hochfesten Aluminiumteilen erforderlichen Verfahrensschritte laufen durchgängig, nacheinander getaktet sowie gesteuert in einem Folgeverbundwerkzeug oder in einem Transferwerkzeug ab. Unmittelbar nach dem Abrollen vom Coil wird das vorher gerichtete Blechband, bzw. die Platinen im angrenzenden mehrstufigen Werkzeug in einer Schienenbahn oder zwischen Greiferbacken einer Greifvorrichtung gehalten, positioniert und geführt.
This problem is solved by the patent claim 1, and supplemented by the claims 2 and 3, as follows:
  • All required for the qualitative production of sheet metal parts made of magnesium and high-strength aluminum parts process steps run consistently, one after the other timed and controlled in a progressive tool or in a transfer tool. Immediately after unwinding from the coil, the previously directed sheet metal strip or the blanks are held and guided in the adjacent multi-stage tool in a rail track or between gripper jaws of a gripping device.

Nacheinander ablaufend erfahren das Blechband oder die geschnittenen in einer Eingangs-Position eine grundhafte, durchgängige Erwärmung auf und zwischen Heizkomponenten. In einer Folge weiterer gereihter Fertigungs-Positionen ist

  • ein mehrfaches Schneiden, Formen und Ausschneiden mittels Einzelwerkzeugstufen und gleichzeitig
  • eine ausreichend ergänzende Aufwärmung auf die Temperatur der in der Eingangsposition erzeugten Erwärmung des Blechbandes, der Platinen oder der Blechteile zum Zwecke einer Temperatur-Konstanthaltung an den Aktivflächen der Einzelwerkzeugstufen, ausgehend von Basispunktstellungen realisierbar.
Sequentially, the sheet metal strip or the cut in an input position experience a thorough, continuous heating on and between heating components. In a row of further ordered production positions is
  • a multiple cutting, shaping and cutting by means of individual tool stages and simultaneously
  • a sufficiently complementary heating to the temperature of the generated in the input position heating of the sheet metal strip, the boards or the sheet metal parts for the purpose of a temperature-constant maintenance on the active surfaces of the individual tool stages, starting from base point positions feasible.

In einer Ableit- und Auswurf-Position sind die fertig hergestellten Blechteile aus dem mehrstufigen Werkzeug mittels teilespezifisch strukturierter Transportmittel ableit- und abtransportierbar.In a discharge and ejection position, the finished sheet metal parts from the multi-stage tool can be dissipated and transported away by means of part-specific structured transport means.

Weitere Verfahrensgestaltungen sind in den Patentansprüchen 2 und 3 angegeben: Sie betreffen die Struktur, die Anordnung und Dimensionierung der Einzelwerkzeugstufen im Ober- sowie im Unterteil eines Folgeverbundwerkzeuges oder Transferwerkzeuges sowie Bedingungen einer partiellen Aufheizung auf die Arbeitstemperaturen und eine gerichtete und entgegengerichtete Wärmeausdehnung durch eine definierte Wärmeentwicklung, sowie Regelbarkeit.Further process designs are specified in claims 2 and 3: They relate to the structure, the arrangement and dimensioning of the individual tool stages in the upper and in the lower part of a follow-on composite tool or transfer tool and conditions of partial heating to the working temperatures and a directed and opposite thermal expansion by a defined heat development , as well as controllability.

Durch die in den Patentansprüchen benannten Verfahrensmerkmale werden die benannten Nachteile des Standes der Technik überwunden und die Problemstellungen gelöst.By the method features mentioned in the claims, the stated disadvantages of the prior art are overcome and solved the problems.

Die Erfindung und ihre Anwendung ist im folgenden Teil der Beschreibung ergänzend erläutert. In den Figuren 1 und 2 ist das Verfahren, in einem mehrstufigen Werkzeug ablaufend, vereinfacht mit einer geringen Stufenanzahl ausgestattet grafisch dargestellt.The invention and its application is explained in the following part of the description in addition. In the FIGS. 1 and 2 is the process, running in a multi-stage tool, simplified with a low number of steps equipped graphically.

Das von mehreren Spezialunternehmen bereitgestellte Magnesium- und Aluminiumblech für flächige Bauteile ist wie in Fig. 1 dargestellt als dünnes Blechband 10 von einem Coil 7 direkt abnehm- und abrollbar.

Für die weitere Verfahrensdurchführung steht ein Temperatur-Prozessfenster zur Verfügung, da auch der Magnesiumwerkstoff eine spezifische Arbeitstemperatur für seine Verarbeitung in guter Qualität benötigt.In its input position 1 is a brief basic heating of the sheet metal strip 10 by means of flat heating components 5 instead. For the further process implementation, a temperature process window is available, since the magnesium material also requires a specific working temperature for its processing in good quality.

  • die Konstanthaltung einer einheitlichen Arbeitstemperatur, ohne Überhitzungseffekte sowie
  • eine geringe und gleichbleibende oder ausgeglichene Eigentemperatur der Einzelwerkzeugstufen sowie der Temperaturen in den Ober- und Unterteilen des Folgeverbundwerkzeuges 4.

  • the constant maintenance of a uniform working temperature, without overheating effects as well
  • a low and constant or balanced natural temperature of the individual tool stages and the temperatures in the upper and lower parts of the progressive tool 4.

Die qualitätsbestimmende Positionierung und Führung des Blechbandes 10 gewährleistet die Schienenbahn 6 über die gesamte Länge des Folgeverbundwerkzeuges 4. In den Ableit- und Auswurf-Positionen 3 des Folgeverbundwerkzeuges 4 erfolgt die Ableitung der fertig hergestellten Magnesiumblech-Teile 11 über Rutschen in das behälterförmige Transportmittel 8 und Ableitung des Restmateriales der Blechbänder 10 in passende palettenartige Transportmittel 9.The quality-determining positioning and guiding the sheet metal strip 10 ensures the rail track 6 over the entire length of the progressive tool 4. In the discharge and ejection positions 3 of the progressive tool 4, the derivation of the finished magnesium sheet parts 11 takes place via slides in the container-shaped transport 8 and Derivation of the residual material of the metal strips 10 in suitable pallet-like transport 9th
