Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Warmumformen metallischer Rohlinge bestehend aus einer Kurbelpresse mit Kniehebelgetriebe zur Herstellung flacher, ringförmiger Werkstücke mit vorbestimmten Abmessungen.The The invention relates to a device for hot forming metallic Blanks consisting of a crank press with a toggle mechanism for the production of flat, ring-shaped workpieces with predetermined dimensions.
Die Herstellung solcher Werkstücke erfolgt üblicherweise durch Warmumformen, auch als Warmschmieden bezeichnet, mit mechanischen Pressen. Der Antrieb mechanischer Pressen erfolgt über verschiedene Systeme, wie z. B. Exzenterpressen und Reibspindelpressen. Derartige Pressen werden zur Fertigung von Werkstücken aus metallischen Rohlingen verwendet, die in großer Stückzahl benötigt werden. Sie weisen jeweils obere und untere Gesenke sowie Auswerfer auf.The Production of such workpieces usually takes place by hot forming, also known as hot forging, with mechanical presses. Mechanical presses are driven by various systems, such as z. B. eccentric presses and reaming presses. Such presses are used to manufacture workpieces made of metallic blanks, which are required in large numbers. You assign each upper and lower dies as well as ejectors.
Ein ernstes Problem ist die Kühlung der Werkzeuge, der Auswerfer und anderer hoch beanspruchter Einzelteile. Eine Erhöhung der Hubzahlen führt zur Überhitzung der Umformwerkzeuge verbunden mit der Verkürzung des erforderlichen Zeitintervalls für Schmierung und Kühlung – somit zur Unwirksamkeit herkömmlicher Kühl- bzw. Schmiereinrichtungen. Die Folgen sind unbeherrschbare Temperaturentwicklungen im Werkzeugsystem.On cooling is a serious problem of tools, ejectors and other highly stressed individual parts. An increase of the stroke rates for overheating of the forming tools combined with the shortening of the required time interval for lubrication and cooling - thus for the ineffectiveness of conventional Cooling or Lubricators. The consequences are uncontrollable temperature developments in the tool system.
Aus der Patentliteratur sind nur wenige Lösungen zur Bewältigung des Problems der Kühlung beim Pulverpressen und Warmumformen bekannt.Out the patent literature are only a few solutions to deal with the problem of cooling when Powder presses and hot forming are known.

Der Erfindung lag deshalb das Problem zugrunde, eine Vorrichtung zur Warmumformung von metallischen Rohlingen zur Herstellung flacher, ringförmiger Werkstücke bei Hubzahlen über 30 Hub/Minute zu entwickeln.The The invention was therefore based on the problem of a device for Hot forming of metal blanks for the production of flat, annular workpieces at stroke rates over 30 stroke / minute to develop.
Dieses Problem wird erfindungsgemäß durch eine Vorrichtung zum Warmumformen mit den Merkmalen des Patentanspruches 1 gelöst.This According to the invention, the problem is solved by a device for hot forming with the features of the claim 1 solved.
Danach ist die Vorrichtung gekennzeichnet durch folgende Merkmale:
- 1. Im oberen Werkzeugzwischenhalter
1 , verbunden mit dem oberen Grund-Gesenk2 , ist eine Überströmkammer3 für ein Kühlmittel enthalten, die 1.1 ringförmig um den oberen Auswerferschaft4 angeordnet ist und 1.2 eine Zuführung5 für ein Kühlmittel aufweist, wobei 1.3 als Kühlmittel bevorzugt verflüssigter Stickstoff verwendet wird. - 2. Der obere Auswerfer
6 , zentrisch im oberen Grund-Gesenk2 angeordnet, weist Bohrungen7 für den Kühlmittelaustritt auf, wobei der Auswerfer6 2.1 jeweils sechs Bohrungen7 , kreisförmig angeordnet, aufweist. - 3. Der untere Werkzeugzwischenhalter
8 , verbunden mit dem unteren Grund-Gesenk9 , weist zwei gegeneinander abgedichtete Sprühmittelkreisläufe10 und11 auf, wobei 3.1 der untere Sprühmittelkreislauf10 mit einem hochviskosen Schmiermittel und 3.2 der obere Sprühmittelkreislauf11 mit einem niedrigviskosen Schmiermittel beaufschlagt wird. - 4. Der untere Auswerfer
12 über den unteren Auswerferschaft13 mit den Sprühmittelkreisläufen10 und11 verbunden ist und Sprühöffnungen14 und15 aufweist, wobei 4.1 die Öffnungen14 für den unteren Sprühmittelkreislauf10 zentrisch und 4.2 die Öffnungen15 für den oberen Sprühmittelkreislauf11 kreisförmig angeordnet sind.
- 1. In the upper intermediate tool holder
1 , connected to the upper base die2 , is an overflow chamber3 for a coolant included, the 1.1 ring around the upper ejector shaft4 is arranged and 1.2 a feed5 for a coolant, 1.3 being preferably used as the coolant liquefied nitrogen. - 2. The upper ejector
6 , centered in the upper base die2 arranged, has holes7 for the coolant outlet, with the ejector6 2.1 six holes each7 , arranged in a circle. - 3. The lower intermediate tool holder
8th , connected to the lower basic die9 , has two mutually sealed spray circuits10 and11 3.1, the lower spray circuit10 with a highly viscous lubricant and 3.2 the upper spray circuit11 is charged with a low-viscosity lubricant. - 4. The lower ejector
12 over the lower ejector13 with the spray circuits10 and11 is connected and spray orifices14 and15 has 4.1, the openings14 for the lower spray circuit10 centric and 4.2 the openings15 for the upper spray circuit11 are arranged in a circle.
Die erfindungemäße Vorrichtung ermöglicht durch Veränderungen im Gesenkbereich bzw. im Bereich der Werkzeugzwischenhalter in Verbindung mit der Kühlmittelzuführung und geeigneten Schmiermittelkreisläufen eine Erhöhung der Hubzahlen auf 40 Hub/Minute und damit eine Verkürzung der Fertigungszeiten bei thermisch stabilen Warmumformprozessen. Ein weiterer Vorteil der Erfindung besteht darin, daß entgegen herkömmlicher Kühlung und Schmierung neben der Kühlung bzw. Schmierung der Auswerfer und Auswerferschäfte auch das gesamte Werkzeug thermisch stabil gehalten werden kann.The Device according to the invention made possible by changes in the die area or in the area of the intermediate tool holder with the coolant supply and suitable lubricant circuits an increase the number of strokes to 40 strokes / minute and thus a reduction in Manufacturing times for thermally stable hot forming processes. On Another advantage of the invention is that contrary to conventional cooling and lubrication in addition to cooling or lubrication of the ejector and ejector shafts also the entire tool can be kept thermally stable.
Die Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:The The invention is explained in more detail below with reference to the drawings. It demonstrate:
Die
erfindungsgemäße Vorrichtung
bzw. Presse wird zur Fertigung flacher, ringförmiger Werkstücke – vorzugsweise
von Synchronringen für
Handschaltgetriebe – verwendet.
Diese Synchronringe bestehen aus handelsüblichen Messingleitlegierungen. Derartige
Pressen arbeiten mit 40 Hub/Minute. Zunächst wird die Überströmkammer
