Abstract

A wire grinding machine has two grinding units (4, 5) on a tool disc (1) revolving around a fixed wire holder (2). Each of the grinding units rests by the front face (12, 13) of a revolving pot-shaped grinding body (10, 11) on different sides of the circumferential surface of the wire (3) to be ground. A cross-grinding effect is thereby obtained on the wire (3), with the result that it has a very smooth surface. <IMAGE>

Description

Die Erfindung betrifft eine Drahtschleifmaschine mit einer zu einer feststehenden Drahtaufnahme umlaufenden Werkzeugscheibe, welche zumindest ein Schleifaggregat mit einem gegen die Mantelfläche des in der Drahtaufnahme geführten Drahtes beweglichen, um eine Drehachse rotierenden Schleifkörper aufweist, welcher topfförmig ausgebildet und min seiner Stirnfläche gegen die Mantelfläche des Drahtes beweglich ist. Eine solche Drahtschleifmaschine ist Gegenstand der DE-A-25 24 208.The invention relates to a wire grinding machine with a rotating tool disk rotating to a fixed wire holder, which has at least one grinding unit with a movable against the outer surface of the wire guided in the wire holder, rotating about an axis of rotation grinding body, which is cup-shaped and with its end face against the outer surface of the wire is mobile. Such a wire grinding machine is the subject of DE-A-25 24 208.

Die genannte DE-A-25 24 208 befaßt sich mit dem Problem des Festsetzens des Schleifstaubes in den Schleifflächen. Verhindert werden soll dieses Festsetzen durch zwei mit parallelen Schleifflächen einander gegenüberliegende, sich um eine gemeinsame Achse gegenläufig drehende und gemeinsam um die Drahtachse rotierende Schleifscheiben, wobei der Draht entlang dem Durchmesser der Schleifzone geführt wird. Durch diese Anordnung der Schleifscheiben wird stets rechtwinklig zur Längsachse des Drahtes geschliffen. Dadurch entsteht durch den Drahtvorschub ein schraubenlinienartiger Verlauf der Schleifriefen, was für die Schleifgüte nachteilig ist.The aforementioned DE-A-25 24 208 deals with the problem of the grinding dust becoming stuck in the grinding surfaces. This locking is to be prevented by two grinding wheels lying opposite one another with parallel grinding surfaces, rotating in opposite directions about a common axis and rotating together around the wire axis, the wire being guided along the diameter of the grinding zone. This arrangement of the grinding wheels always grinds at right angles to the longitudinal axis of the wire. As a result, the wire feed creates a helical course of the grinding grooves, which is disadvantageous for the grinding quality.

Durch die DE-C-25 19 451 ist es auch schon bekannt, bei einer Drahtschleifmaschine einander gegenüberliegend zwei Schleifaggregate vorgesehen, welche jeweils ein quer zum Draht umlaufendes Schleifband aufweisen. Dieses wird von Führungsrollen gegen den Draht gedrückt. Auch durch diese Ausbildung der Drahtschleifmaschine entsteht auf dem Draht ein Querschliff, welcher infolge der Vorschubbewegung schraubenförmig verläuft.From DE-C-25 19 451 it is also known to provide two grinding units opposite one another in a wire grinding machine, each of which has an abrasive belt running transversely to the wire. This is pressed against the wire by guide rollers. This design of the wire grinding machine also creates a cross-section on the wire, which is helical due to the feed movement.

Es hat sich gezeigt, daß die mit den bekannten Drahtschleifmaschinen erreichbare Oberflächengüte des geschliffenen Drahtes oftmals nicht ausreichend ist. Das gilt auch dann, wenn der Draht nach dem Schleifen weiteren Ziehprozessen unterworfen wird, weil dabei seine Oberflächenstruktur nur in eine Richtung langgezogen wird.It has been shown that the surface quality of the ground wire that can be achieved with the known wire grinding machines is often not sufficient. This also applies if the wire is subjected to further drawing processes after grinding because its surface structure is only drawn in one direction.

Allgemein ist es in der Schleiftechnik üblich, Oberflächen mit einem Kreuzschliff zu versehen, falls eine besonders hohe Oberflächengüte verlangt wird. Ein solcher Kreuzschliff bedingt erheblich größeren Aufwand als ein Quer- oder Längsschliff. Bedenkt man, daß bei Drahtschleifmaschinen ein relativ dünner Draht mit möglichst hoher Vorschubgeschwindigkeit durch die Maschine läuft und dabei geschliffen werden muß, so wird verständlich, daß bislang noch keine Drahtschleifmaschinen entwickelt wurden, welche einen Kreuzschliff auf der Drahtoberfläche ermöglichen.In general, it is common in grinding technology to provide surfaces with a cross grind if a particularly high surface quality is required. Such a cross section requires considerably more effort than a cross or longitudinal section. If you consider that in wire grinding machines a relatively thin wire runs through the machine at the highest possible feed rate and has to be ground in the process, it is understandable that no wire grinding machines have yet been developed which enable cross grinding on the wire surface.

Der Erfindung liegt die Aufgabe zugrunde, eine Drahtschleifmaschine der eingangs genannten Art so auszubilden, daß sich mit ihr ein Kreuzschliff auf der Drahtoberfläche erzielen läßt, ohne daß hierzu die Drahtschleifmaschine aufwendig gestaltet sein muß.The invention is based on the object of designing a wire grinding machine of the type mentioned at the outset in such a way that it can be used for cross grinding on the wire surface without the wire grinding machine having to be designed in a complex manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Drehachse des Schleifkörpers seitlich der Längsachse der Werkzeugscheibe und damit auch der des Drahtes verläuft und maximal so viel Abstand von der Längsachse hat, wie es dem Radius der Innenmantelfläche des Schleifkörpers entspricht, so daß bei maximalem Abstand die Längsachse eine Tangente zur Innenmantelfläche des Schleifkörpers bildet.This object is achieved in that the axis of rotation of the grinding wheel extends to the side of the longitudinal axis of the tool disc and thus also that of the wire and has a maximum distance from the longitudinal axis that corresponds to the radius of the inner surface of the grinding wheel, so that the maximum distance Longitudinal axis forms a tangent to the inner surface of the grinding wheel.

Durch diese Gestaltung der Drahtschleifmaschine ist der Schleifkörper in der Lage, in einem Arbeitsgang den Draht in den unterschiedlichsten Schrägrichtungen zu schleifen. Dadurch entsteht eine sehr hohe Oberflächengüte. Dennoch sind mit der erfindungsgemäßen Drahtschleifmaschine hohe Vorschubgeschwindigkeiten zu erreichen. Bei dem topfförmigen Schleifkörper kann es sich um einen handelsüblichen Schleifkörper handeln, welcher problemlos und kostengünstig erhältlich ist.This design of the wire grinding machine enables the grinding body to grind the wire in a wide variety of diagonal directions in one operation. This creates a very high surface quality. Nevertheless, high feed speeds can be achieved with the wire grinding machine according to the invention. The cup-shaped grinding wheel can be a commercially available grinding wheel which can be obtained easily and inexpensively.

Besonders vorteilhaft ist es, wenn die Längsachse der Werkzeugscheibe und damit auch die des Drahtes eine Tangente zur Innenmantelfläche des Schleifkörpers bildet. Dadurch kommt während des Scheifvorganges durch die Rotationsbewegung des Schleifkörpers die gesamte Stirnfläche des Schleifkörpers mit der Drahtoberfläche in Berührung, so daß der Schleifkörper gleichmäßig abgenutzt wird. Weiterhin ergibt sich hierdurch ein exakter Kreuzschliff.It is particularly advantageous if the longitudinal axis of the tool disk and thus also that of the wire forms a tangent to the inner surface of the grinding wheel. As a result, the entire end face of the grinding body comes into contact with the wire surface during the grinding process due to the rotational movement of the grinding body, so that the grinding body is evenly worn. This also results in an exact cross-cut.

Die beim Schleifen auf den Draht wirkenden Kräfte heben sich gegenseitig auf, wenn gemäß einer vorteilhaften Ausgestaltung der Erfindung auf der Werkzeugscheibe auf gegenüberliegenden Seiten insgesamt zwei Schleifaggregate vorgesehen sind.The forces acting on the wire during grinding cancel each other out if, according to an advantageous embodiment of the invention, a total of two grinding units are provided on the tool disc on opposite sides.

Die Werkzeugscheibe ist gewichtsausgeglichen, so daß relativ hohe Umlaufgeschwindigkeiten möglich werden, wenn die beiden Schleifaggregate bezogen auf eine durch die Mitte der Werkzeugscheibe verlaufende Mittellinie in unterschiedliche Richtungen nach außen hin versetzt sind, so daß die Stirnflächen der topfförmigen Schleifkörper unterschiedliche Quadrante des zu schleifenden Drahtes abdecken.The tool disc is weight-balanced so that relatively high rotational speeds are possible if the two grinding units are offset in different directions with respect to a center line running through the center of the tool disc, so that the end faces of the cup-shaped grinding bodies cover different quadrants of the wire to be ground .

Besonders hohe Schleifleistungen bei hoher Schleifqualität lassen sich erzielen, wenn in der Werkzeugscheibe mit ihr umlaufende, auf die Schleifstelle gerichtete Kühlmittelaustrittsdüsen angeordnet sind.Particularly high grinding performance with high grinding quality can be achieved if coolant outlet nozzles are arranged in the tool disc with its circumferential, directed towards the grinding point.

Auf eigene Antriebe für die beiden Schleifaggregate kann verzichtet werden, wenn gemäß einer anderen Ausgestaltung der Erfindung die Schleifaggregate getrieblich mit einem nicht mit der Werkzeugscheibe umlaufenden, beiden Schleifaggregaten gemeinsamen Motor verbunden sind. Diese Ausgestaltung ermöglicht es auch, die Werkzeugscheibe gegen eine Werkzeugscheibe mit üblichen Bandschleifaggregaten auszutauschen.There is no need for separate drives for the two grinding units if, according to another embodiment of the invention, the grinding units are connected in a geared manner to a motor which is not rotating with the tool disk and which is common to both grinding units. This configuration also makes it possible to replace the tool disk with a tool disk with conventional belt grinding units.

Ein besonders gleichmäßiger Verschleiß beider Schleifscheiben läßt sich erzielen, wenn die Zustellbewegungen der Schleifaggregate miteinander gekoppelt sind.A particularly uniform wear of both grinding wheels can be achieved if the feed movements of the grinding units are coupled to one another.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon stark schematisch in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt in

The invention allows numerous embodiments. To further clarify its basic principle, one of them is shown very schematically in the drawing and is described below. This shows in
Fig. 1
a view from the front of a tool disc of the wire grinding machine with the adjacent components,
Fig. 2
a plan view of the area of the grinding point.

Die Figur 1 zeigt eine Werkzeugscheibe 1, welche um eine ortsfeste Drahtaufnahme 2 herum drehbar gelagert ist. In der Drahtaufnahme 2 ist ein zu schleifender Draht 3 in Längsrichtung verschieblich geführt. Auf der Werkzeugscheibe 1 sind zwei Schleifaggregate 4, 5 angeordnet, welche jeweils auf Führungen 6, 7 und 8, 9 verfahrbar sind. Beide Schleifaggregate 4, 5 weisen jeweils einen topfförmigen Schleifkörper 10, 11 auf, der mit seiner Stirnfläche 12, 13 gegen den zu schleifenden Draht 3 anliegt und auf nicht gezeigte Weise in eine Drehbewegung um jeweils eine Drehachse 20, 21 zu versetzen ist.FIG. 1 shows a tool disk 1 which is rotatably mounted around a fixed wire holder 2. A wire 3 to be ground is displaceably guided in the longitudinal direction in the wire receptacle 2. Two grinding units 4, 5 are arranged on the tool disk 1, each of which can be moved on guides 6, 7 and 8, 9. Both grinding units 4, 5 each have one Pot-shaped grinding body 10, 11, which rests with its end face 12, 13 against the wire 3 to be ground and is to be set in a manner not shown in a rotary movement about a respective axis of rotation 20, 21.

Die beiden Schleifaggregate 4, 5 sind bezogen auf eine durch die Mitte des Drahtes 3 führende Mittellinie 14 jeweils nach außen hin so weit versetzt, daß die Innenmantelfläche 15, 16 jedes Schleifkörpers 10, 11 genau mit der Längsachse 17 des Drahtes 3 fluchtet. Ein geringerer Versatz ist auch möglich, jedoch dürfen die Drehachsen 20, 21 nicht mit der Längsachse 17 des Drahtes 3 fluchten, weil dann statt des gewünschten Kreuzschliffes nur ein Querschliff entstehen würde.The two grinding units 4, 5 are each offset so far with respect to a center line 14 leading through the center of the wire 3 that the inner lateral surface 15, 16 of each grinding body 10, 11 is exactly aligned with the longitudinal axis 17 of the wire 3. A smaller offset is also possible, however, the axes of rotation 20, 21 must not be aligned with the longitudinal axis 17 of the wire 3, because then only a cross-cut would result instead of the desired cross-cut.

Die Figur 1 läßt weiterhin in der Werkzeugscheibe 1 zwei mit ihr umlaufende Kühlmitteldüsen 18, 19 erkennen, die Kühlmittel zu den beiden Schleifstellen zu spritzen vermögen.FIG. 1 also shows in the tool disk 1 two coolant nozzles 18, 19 rotating with it, which are able to inject coolant to the two grinding points.

In Figur 2 sind die beiden sich überlappenden Schleifkörper 10, 11 zu erkennen. Man sieht, daß die Längsachse 17 der Werkzeugscheibe 1 und damit auch die des Drahtes 3 eine Tangente zu den Innemantelflächen 15, 16 der Schleifkörper 10, 11 bildet. Dadurch wird durch den Schleifvorgang jeweils die gesamte Stirnfläche der Schleifkörper 10, 11 abgenutzt.The two overlapping grinding bodies 10, 11 can be seen in FIG. It can be seen that the longitudinal axis 17 of the tool disk 1 and thus also that of the wire 3 forms a tangent to the inner jacket surfaces 15, 16 of the grinding bodies 10, 11. As a result, the entire end face of the grinding bodies 10, 11 is worn out by the grinding process.
