Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Tiefziehen von Blechen, vorzugsweise aus höherfesten Stählen und/oder Mehrphasenstählen oder aus Aluminium gemäß Oberbegriff des Anspruches 1 und auf ein Tiefziehwerkzeug, vorzugsweise zur Anwendung bei diesem Verfahren gemäß Oberbegriff des Anspruches 5.The Invention relates to a method for deep drawing sheet metal, preferably of higher strength toughen and / or multi-phase steels or made of aluminum according to the generic term of claim 1 and on a deep-drawing tool, preferably for Use in this method according to the preamble of the claim 5th
Beim
zum Stand der Technik gehörigen
Tiefziehverfahren wird die Z-Richtung der Presse im Verformungsprozess
im Ziehwerkzeug so genutzt, daß die
Verformung ebenfalls in der Z-Richtung erfolgt. Ein zum Stand der
Technik gehöriges
Ziehwerkzeug ist in
Der Erfindung liegt die Aufgabe zugrunde ein Verfahren zum Tiefziehen und ein entsprechendes Tiefziehwerkzeug zur Anwendung bei diesem Verfahren vorzuschlagen, bei dem derartige Markierungen an der Anzugskante verhindert werden.The The invention is based on the object of a method for deep drawing and a corresponding deep-drawing tool for use with this Propose a process in which such markings on the tightening edge be prevented.
Die Lösung dieser Aufgabe ist in den Patentansprüchen 1 und 5 angegeben. Die Unteransprüche 2 bis 4 und 6 bis 9 enthalten sinnvolle ergänzende Maßnahmen bzw. Ausführungsformen dazu.The solution this object is specified in claims 1 and 5. The under claims 2 to 4 and 6 to 9 contain useful additional measures or embodiments to.
Bei dem erfindungsgemäßen Verfahren wird zum Ende und/oder nach Beendigung des in Z-Richtung erfolgenden Pressenhubes mit Hilfe eines oder mehrerer in und/oder an der Matrize angeordneter Schieber das Blech in dem kritischen Bereich, in dem sich Markierungen bilden können, von außen in Richtung gegen den steilen Randbereich des Ziehstempels gepreßt. Durch die zusätzliche Umlenkung der Pressenrichtung über einen oder mehrere Schieber, werden Probleme, die durch das reine Umformen in Z-Richtung entstehen, reduziert. Mit der erfindungsgemäßen Schieberbewegung im Ziehvorgang lassen sich die erwähnten Markierungen im Sichtbereich und damit eine spätere Nachbearbeitung der Bleche vermeiden. Es lassen sich sehr steile Geometriebereiche erst schräg ziehen und dann im selben Pressenhub durch eine relative Bewegung im Werkzeug steil stellen, ohne daß sich die Ziehmatrize mit dem Matrizenradius reibend über den Bauteilbereich bewegt.at the inventive method becomes at the end and / or after the end in the Z direction Press stroke with the help of one or more in and / or on the die arranged slide the sheet metal in the critical area in which Can form markings from the outside pressed against the steep edge of the punch. By the additional Redirection of the press direction over One or more sliders will be problems caused by the pure Forming in the Z direction is reduced. With the slide movement according to the invention in the drawing process, the markings mentioned can be seen in the viewing area and hence a later one Avoid finishing the sheets. It can be very steep Geometric areas only at an angle pull and then in the same press stroke by a relative movement set steeply in the tool without the drawing die rubbing over the die radius moved the component area.
Die Schieberbewegung erfolgt erfindungsgemäß schräg, vorzugsweise in einem Winkel von 30 – 45° zur Z-Richtung. Auf diese Weise kann eine einfache und schonende Umformung des Bleches erreicht werden.The According to the invention, slide movement takes place obliquely, preferably at an angle from 30 - 45 ° to the Z direction. In this way, a simple and gentle forming of the sheet can be done can be achieved.
Die
Bewegung der Schieber zum gewünschten
Zeitpunkt wird durch Gleiten auf schräg angeordneten Flächen des
Schiebers und in geeigneter Weise am Pressenoberteil oder am Untergestell
angeordneter Ansätze
erreicht. Die schräge
Bewegung der Schieber erfolgt vorzugsweise erst, wenn der in Z-Richtung
durchgeführte
eigentliche Ziehhub beendet ist. Daß kann dadurch bewirkt werden,
daß die Matrize
selbst nicht mehr bewegt wird und ein am Pressenoberteil angeordneter
Ansatz mit einer Schräge
weiter in Z-Richtung bewegt wird (vgl.
