Abstract
Description
Die Erfindung betrifft ein Verfahren zur kontinuierlichen Herstellung von Metalldrähten
nach dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung nach dem Oberbegriff
des Anspruchs 6.The invention relates to a method for the continuous production of metal wires
according to the preamble of
In der Industrie, insbesondere in der Elektroindustrie besteht ein großer Bedarf an metallischen Flachdrähten. Unter einen Flachdraht wird im allgemeinen ein Draht mit rechteckigem Querschnitt verstanden, dessen Dicke im Verhältnis zur Breite wesentlich geringer ist.There is a great need in industry, especially in the electrical industry metallic flat wires. Under a flat wire is usually a wire understood rectangular cross-section, the thickness in relation to the width essential is less.
Die Herstellung derartiger Flachdrähte erfolgt nach der herkömmlichen Weise durch Walzen von Runddrähten. Als Vormaterial werden üblicherweise die sogenannten kostengünstig nach dem Gießwalzverfahren herstellbaren Properzidrähte eingesetzt.The manufacture of such flat wires takes place in the conventional manner Rolling round wires. The so-called Properzid wires that can be produced cost-effectively by the casting and rolling process.
Die Runddrähte werden zunächst auf einer Mehrfachziehanlage heruntergezogen und dann in einem abschließenden Walzvorgang zu dem Flachdraht umgeformt.The round wires are first pulled down on a multiple drawing machine and then formed into the flat wire in a final rolling process.
Der Nachteil dieser Vorgehensweise ist darin zu sehen, daß das Walzen aufgrund der hohen Wärmeentwicklung relativ langsam ist. Darüberhinaus ist der Walzvorgang recht wartungsintensiv. The disadvantage of this procedure is the fact that the rolling due to the high heat is relatively slow. In addition, the rolling process is right maintenance.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem Flachdrähte in einem Arbeitsgang aus Runddrähten in wirtschaftlicher Weise hergestellt werden können.The present invention has for its object to provide a method with the flat wires in one operation from round wires in an economical way can be produced.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 erfaßten Merkmale
gelöst.This object is achieved by the features recorded in the characterizing part of
Der wesentliche Vorteil der Erfindung ist darin zu sehen, daß der Arbeitsschritt "Abflachen" in den mit hoher Geschwindigkeit durchgeführten Ziehvorgang integriert wird. Dabei wird kein Flachdraht mit exakt rechteckigem Querschnitt erzeugt, sondern ein Draht mit einem Querschnitt, bei dem die langen Seiten parallel zueinander verlaufen und die schmalen Seiten gerundet sind.The main advantage of the invention is the fact that the step "Flattening" integrated in the drawing process carried out at high speed becomes. No flat wire with an exactly rectangular cross-section is produced, but instead a wire with a cross section in which the long sides are parallel to each other run and the narrow sides are rounded.
Die nach der Lehre der Erfindung herstellbaren Flachdrähte finden bevorzugt Anwendung als Abschirmdrähte von elektrischen Kabeln und Leitungen. Sie sind in der Lage, bei gleichem Metallgewicht eine größere Fläche abzudecken und führen somit zu erheblichen Einsparungen an Gewicht und Kosten bei den Kabeln und Leitungen.The flat wires that can be produced according to the teaching of the invention are preferred Use as shielding wires for electrical cables and wires. they are in the Able to cover a larger area with the same metal weight and thus lead to considerable savings in weight and costs for cables and wires.
Insbesondere, wenn die Flachdrähte ein Verhältnis von Dicke zu Breite von weniger als 1: 5 aufweisen, lassen sich die Flachdrähte auf Flechtanlagen zu einem Geflecht verarbeiten.Especially when the flat wires have a thickness to width ratio of less than 1: 5, the flat wires can be braided on braiding systems to process.
Neben der Möglichkeit, das Verformen des Runddrahtes zu einem Flachdraht im selben Arbeitsschritt wie das Ziehen des Runddrahtes quasi als letzte Arbeitsstufe durchzuführen, besteht auch die Möglichkeit, im Anschluß an den Ziehvorgang im Wege eines Umwickelvorgangs von einer Spule auf die andere den runden Draht zu einem Flachdraht umzuformen.In addition to the possibility of deforming the round wire into a flat wire in the same To carry out work step like drawing the round wire as the last work step, there is also the possibility of following the drawing process by means of a Wrapping from one spool to the other round wire to one Form flat wire.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen erfaßt.Further advantageous embodiments of the invention are covered in the subclaims.
Die Erfindung ist anhand der in den Figuren 1 und 2 schematisch dargestellten Ausführungsbeispiele näher erläutert. The invention is illustrated schematically in FIGS. 1 and 2 Exemplary embodiments explained in more detail.
Figur 1 zeigt eine seitliche Ansicht einer Ziehmatrize 1, die aus einem Unterteil 2 und
einem Oberteil 3 aufgebaut ist. Das Unterteil 2 ist vorzugsweise fest auf einer Unterlage
angeordnet. Das Oberteil 3 ist ebenfalls in seiner Lage zum Unterteil 2 festgelegt, der
Abstand von Unterteil 2 zu Oberteil 3 ist jedoch vorstellbar.Figure 1 shows a side view of a
Unterteil 2 und Oberteil 3 weisen je einen Einlaufbereich 2a und 3a auf, der zur Kühlung
der Matrize 1 dient. In Fertigungsrichtung gesehen - in der Figur nach rechts - folgen
der Umformbereich 2b und 3b sowie der Kalibrierbereich 2c und 3c, welcher die Dicke
des Flachdrahtes bestimmt. Der Auslaufbereich ist mit 2d und 3d bezeichnet.
Wie die Figur 1 verdeutlicht, wird der Runddraht 4 durch die aus Unterteil 2 und Oberteil
3 bestehende Matrize 1 durch einen Ziehvorgang allmählich zu einem Flachdraht 5
umgeformt. Dadurch, daß die Matrize 1 zu den Seiten hin offen ist, ist der Querschnitt
des Flachdrahtes nicht rechteckförmig, sondern die Schmalseiten verlaufen gekrümmt,
was daraus resultiert, daß die Verformung im eigentlichen Sinne eine Abflachung bzw.
ein Quetschvorgang ist.As illustrated in FIG. 1, the
Figur 2 zeigt eine Ansicht der Matrize 1 entgegen der Fertigungsrichtung. Hier ist klar
erkennbar, daß die Matrize 1 kein geschlossenes Kaliber zeigt.Figure 2 shows a view of the
Um eine seitliche Verschiebung des Runddrahtes 4 bzw. des Flachdrahtes 5 zu
vermeiden, können nicht dargestellte Führungen vor und/oder hinter der Matrize 1
vorgesehen sein.To a lateral displacement of the
Die in den Figuren 1 und 2 dargestellte Matrize 1 kann als letzte Ziehstufe in einer
kontinuierlich arbeitenden Mehrfachziehanlage eingesetzt werden, wobei auch mehrere
erfindungsgemäße Matrizen hintereinander angeordnet sein können, um eine
allmähliche Verformung bis zum endgültigen Querschnitt des Flachdrahtes 5 zu
ermöglichen. Die Verformung kann mit einer Querschnittsreduzierung einhergehen, es
können jedoch auch die Querschnitte von Rund- und Flachdraht größenordnungsmäßig
gleich sein. The die 1 shown in FIGS. 1 and 2 can be used as the last drawing stage in a
continuously operating multiple drawing system are used, with several
Matrices according to the invention can be arranged one behind the other in order to
gradual deformation up to the final cross section of the
Die erfindungsgemäße Matrize kann auch beim Umspulen von einer ersten Spule zu einer zweiten Spule eingesetzt werden, wobei der von der ersten Spule ablaufende Runddraht zu dem Flachdraht verformt wird, der dann auf die zweite Spule aufgewickelt wird.The die according to the invention can also be closed when rewinding from a first spool a second coil are used, the one running from the first coil Round wire is deformed into the flat wire, which is then wound onto the second coil becomes.
Neben den oben erwähnten Vorteilen weist die Erfindung noch den entscheidenden
Vorteil auf, daß die für die Verformung benötigten Oberflächen des Unterteils 2 und des
Oberteils 3 wesentlich einfacher poliert werden können, als es bei Matrizen mit
geschlossenem Kaliber möglich ist.In addition to the advantages mentioned above, the invention also has the decisive one
Advantage on that the surfaces of the
