Description

Die Erfindung betrifft eine Vorrichtung zum Kaltverformen von Metalldraht mit mindestens einer Gruppe von rund um eine Verformungsöffnung für den Draht in einem Werkzeughalter sternförmig angeordneten Verformungsrollen.The invention relates to a device for cold-forming metal wire with at least one group of deformation rollers arranged in a star shape around a deformation opening for the wire in a tool holder.

Derartige Vorrichtungen dienen der Herstellung glatter oder gerippter Drähte und haben im Vergleich zu Drahtzieheinrichtungen mit Verformung des Drahtes in der Ziehdüse den Vorteil einer geringeren Abnützung der Werkzeuge. Bei größeren Verformungsgeschwindigkeiten kommt es jedoch zu Schwierigkeiten mit der Kühlung der Verformungsrollen.Devices of this type are used to produce smooth or ribbed wires and, compared to wire drawing devices with deformation of the wire in the drawing nozzle, have the advantage of less wear on the tools. At higher deformation speeds, however, there are difficulties with cooling the deformation rollers.

Aus der AT-PS 240 314 ist eine Vorrichtung zum Kaltverformen von Metalldraht bekannt, bei der die Verformungsrollen in einem Werkzeughalter verstellbar gelagert und mit einer Innenkühlung ausgestattet sind. Die Verformungsrollen weisen Bohrungen für den Durchfluß eines Kühlmittels auf, die über entsprechende Bohrungen in den Rollenachsen und im Werkzeughalter an einen Kühlmittelkreislauf angeschlossen sind. Auch diese Kühlung hat sich als nicht ausreichend erwiesen, selbst wenn für die bei Ziehdüsen übliche Schmierung gesorgt wird.From AT-PS 240 314 a device for cold-forming metal wire is known, in which the deformation rollers are adjustably mounted in a tool holder and are equipped with internal cooling. The deformation rollers have bores for the flow of a coolant, which are connected to a coolant circuit via corresponding bores in the roller axes and in the tool holder. This cooling has also proven to be insufficient, even if the lubrication customary for drawing nozzles is provided.

Die Schwierigkeiten mit der Kühlung sind bedingt durch die auf engen Raum zusammengedrängte Bauweise des Werkzeughalters mit den Verformungsrollen, die wegen der notwendig kleinen Abmessungen der letzteren unvermeidlich ist.The difficulties with cooling are due to the compact design of the tool holder with the deformation rollers, which is inevitable because of the small dimensions of the latter.

Bei Vorrichtungen (vgl. z.B. AT-PS 309 366), in welchen mehrere Gruppen von rund um die Verformungsöffnung sternförmig angeordneten z.B. je drei oder sechs Verformungsrollen hintereinander auf den zu verformenden Draht einwirkend gelagert sind, sind die Schwierigkeiten mit der Kühlung noch vervielfacht.For devices (see e.g. AT-PS 309 366) in which several groups of e.g. The problems with cooling are multiplied by three or six deforming rollers, one after the other, which act on the wire to be deformed.

Der Erfindung liegt die Aufgabe zugrunde, die Kühlung und Schmierung bei einer solchen Vorrichtung zum Kaltverformen von Metalldraht zu verbessern und damit höhere Verformungsgeschwindigkeiten zu ermöglichen. Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art im wesentlichen dadurch gelöst, daß am Werkzeughalter eine Anzahl von Düsen rund um die Achse des Metalldrahtes angeordnet ist, deren Spritzrichtungen auf die Verformungsöffnung der Gruppe von Verformungsrollen weisen, durch welche eine Schmiermittelemulsion zuführbar ist. Dadurch wird eine wirksame Außenkühlung und zugleich Schmierung der Verformungsrollen direkt im Bereich der Verformungsöffnung erreicht. Dadurch, daß die Düsen rund um die Achse des Metalldrahtes angeordnet und auf die Verformungsöffnung gerichtet sind, wird nicht nur die Kühlung und Schmierung im kritischen Bereich verbessert, sondern es wird, da die Schmiermittelemulsion bei einer solchen Anordnung, auch den Draht selbst trifft, an diesen anhaftender Walzzunder entfernt und damit eine Verbesserung der Oberflächenqualität des verformten Drahtes erreicht.The invention has for its object to improve the cooling and lubrication in such a device for cold forming of metal wire and thus to enable higher rates of deformation. This object is achieved in a device of the type mentioned essentially in that a number of nozzles is arranged around the axis of the metal wire on the tool holder, the spray directions of which point to the deformation opening of the group of deformation rollers through which a lubricant emulsion can be supplied. This achieves effective external cooling and lubrication of the deformation rollers directly in the area of the deformation opening. The fact that the nozzles are arranged around the axis of the metal wire and are directed towards the deformation opening not only improves the cooling and lubrication in the critical area, but it also, because in such an arrangement, the lubricant emulsion also hits the wire itself removes this adhering mill scale and thus improves the surface quality of the deformed wire.

Gemäß der Erfindung sind vorzugsweise vor und hinter jeder Gruppe bzw. je zwei Gruppen von Verformungsrollen Düsen mit entgegengesetzter Spritzrichtung angeordnet, deren Spritzrichtungen auf die Verformungsöffnung oder -öffnungen weisen. Es wird auf diese Weise jede Verformungsrolle von zwei Seiten her im Bereich der Verformungsöffnung beaufschlagt, wodurch die Kühlung noch weiter verbessert wird.According to the invention, nozzles with opposite spray directions are preferably arranged in front of and behind each group or two groups of deformation rollers, the spray directions of which point towards the deformation opening or openings. In this way, each deformation roller is acted on from two sides in the region of the deformation opening, so that cooling is still performed is further improved.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Anordnung so getroffen, daß zwei Gruppen von Verformungsrollen vorgesehen sind, wobei in Achsrichtung des Drahtes gesehen die Verformungsrollen der einen Gruppe gegenüber den Verformungsrollen der anderen Gruppe versetzt sind, daß an den voneinander abgewendeten Seiten der beiden Gruppen der Verformungsrollen Düsen vorgesehen sind, wobei die Düsen so angeordnet sind, daß die Strahlen der Schmiermittelemulsion zwischen den Verformungsrollen der näher gelegenen Gruppe hindurch auf die entferntere Gruppe von Verformungsrollen treffen. Auf diese Weise kann mit einer geringeren Anzahl von Düsen das Auslangen gefunden werden, wobei trotzdem die Verformungsrollen beider Gruppen im Bereich der Verformungsöffnungen von beiden Seiten mit der Schmiermittelemulsion beaufschlagt und gekühlt werden. Es können hiebei einzelne Düsen unmittelbar auf den Zwischenraum zwischen den Verformungsrollen der näher gelegenen Gruppe gerichtet sein oder es können die Randstrahlen der aus den Düsen austretenden Schmiermittelemulsion die Verformungsrollen der entfernter gelegenen Gruppe treffen, so daß die aus den Düsen austretende Schmiermittelemulsion besser ausgenützt wird.According to a preferred embodiment of the invention, the arrangement is such that two groups of deformation rollers are provided, the deformation rollers of one group being offset in relation to the deformation rollers of the other group, as seen in the axial direction of the wire, that on the sides of the two groups facing away from one another Deformation rollers nozzles are provided, the nozzles being arranged so that the jets of the lubricant emulsion hit the distant group of deformation rollers between the deformation rollers of the closer group. In this way, it is possible to find sufficiency with a smaller number of nozzles, although the deformation rollers of both groups in the region of the deformation openings are acted upon and cooled with the lubricant emulsion from both sides. In this case, individual nozzles can be aimed directly at the space between the deformation rollers of the closer group, or the marginal jets of the lubricant emulsion emerging from the nozzles can hit the deformation rollers of the more distant group, so that the lubricant emulsion emerging from the nozzles is better utilized.

Zweckmäßig sind die Düsen nur wenig geneigt zur Achse des Metalldrahtes angeordnet. Hiebei sind vorzugsweise die Spritzrichtungen der Düsen unter 10 bis 250 gegen die Achse des Metalldrahtes geneigt. Durch diese geringe Neigung der Spritzrichtungen zur Achse des Drahtes wird erreicht, daß die Schmiermittelemulsion möglichst in die Verformungsöffnung hineingelangt. Diese geringe Neigung ist insbesondere bei einer Anordnung von Vorteil, bei welcher die Strahlen der Schmiermittelemulsion oder Teile dieser Strahlen zwischen den Verformungsrollen der näher gelegenen Gruppe hindurch auf die Verformungsrollen der entfernter gelegenen Gruppe treffen, da bei einer solchen geringen Neigung der Achse des Metalldrahtes die Strahlen oder Teile der Strahlen noch im Bereich der Verformungsöffnung auf die Verformungsrollen der entfernter gelegenen Gruppe auftreffen.The nozzles are expediently arranged only slightly inclined to the axis of the metal wire. Hiebei the spray directions of the nozzles under 10 to 25 0 are preferably inclined to the axis of the metal wire. Due to this slight inclination of the spray directions to the axis of the wire is achieved that the lubricating emulsion enters possible erformungsöffnung in the V. This slight inclination is particularly advantageous in the case of an arrangement which impinge the rays of the lubricant emulsion or parts of these rays between the deformation rollers of the closer group on the deformation rollers of the more distant group, since with such a slight inclination of the axis of the metal wire, the rays or parts of the rays still hit the deformation rollers in the region of the deformation opening of the more distant group.

Die Düsen können zweckmäßig in axialen Deckeln des Werkzeughalters versenkt angeordnet sein.The nozzles can expediently be countersunk in the axial covers of the tool holder.

Um den Verlust von am verformten Draht anhaftender Schmiermittelemulsion zu vermeiden, ist vorteilhaft, die Achse des Metalldrahtes anschließend an den Austritt desselben aus den Verformungsrollen mit gegen die Laufrichtung des Metalldrahtes angeordneten Druckluftdüsen zu umgeben.In order to avoid the loss of lubricant emulsion adhering to the deformed wire, it is advantageous to surround the axis of the metal wire with compressed air nozzles arranged against the direction of travel of the metal wire after it has left the deformation rollers.

Unterhalb des Werkzeughalters mit den Verformungsrollen kann ein Auffangbehälter für die Schmiermittelemulsion angeordnet sein. Von dort kann die Schmiermittelemulsion nach einer Siebung und Filterung wiederum zu den Düsen ' im Inneren des Werkzeughalters gepumpt werden.A collecting container for the lubricant emulsion can be arranged below the tool holder with the deformation rollers. From there, the lubricant emulsion can be pumped to the nozzles inside the tool holder after sieving and filtering.

Die Erfindung wird anhand der Zeichnung näher erläutert, in deren einziger Figur eine erfindungsgemäße Vorrichtung zum Kaltverformen von Metalldraht schematisch in Seitenansicht dargestellt ist.The invention is explained in more detail with reference to the drawing, in the single figure of which a device according to the invention for cold-forming metal wire is shown schematically in a side view.

Die Vorrichtung weist zwei Gruppen 1, 2 von je rund um eine Verformungsöffnung 3 für den Draht 4 sternförmig angeordneten Verformungsrollen 15 auf. Jede Gruppe 1, 2 besteht aus drei Verformungsrollen 15, die in Winkeln von je 1200 zueinander angeordnet sind, wobei in der Zeichnung zwecks besserer übersichtlichkeit nur je zwei Verformungsrollen eingezeichnet sind. Selbstverständlich kann eine Rollengruppe auch mehr als drei, z.B. sechs Verformungsrollen 15 umfassen. Die Verformungsrollen beider Gruppen 1, 2 sind auf hier nicht näher erläuternde Weise radial einstellbar in einem mit 5 bezeichneten Werkzeughalter gelagert.The device has two groups 1, 2, each around a deformation opening 3 for the wire 4, with deformation rollers 15 arranged in a star shape. Each group 1, 2 consists of three deformation rollers 15, which are arranged at angles of 120 ° to each other, with only two deformations in the drawing for the sake of clarity rolls are shown. Of course, a roller group can also comprise more than three, for example six, deformation rollers 15. The deformation rollers of both groups 1, 2 are mounted in a manner not explained here in a radially adjustable manner in a tool holder denoted by 5.

In axialen Deckeln 6 des Werkzeughalters 5 sind mit 7 bezeichnete Düsen rund um die Achse des Metalldrahtes 4 verteilt angeordnet, welche über eine Ringkammer 8 und eine Bohrung 9 im Deckel 6 an eine bei 10 angedeutete Schmiermittelemulsion-Zufuhrleitung angeschlossen sind. Die Spritzrichtungen der Düsen 7 sind auf die Verformungsöffnung 3 der Gruppe 1 bzw. 2 von Verformungsrollen hin ausgerichtet. Die aus den in der Zeichnung links angeordneten.Düsen 7 austretenden Strahlen der Schmiermittelemulsion können zu einem großen Teil ungehindert zwischen den benachbarten Verformungsrollen 15 der Rollengruppe 1 hindurch auf die nächste Gruppe 2 von Verformungsrollen 15 gelangen, die gegenüber der Rollengruppe 1 drehversetzt sind. Analoges gilt für die aus den in der Zeichnung rechts angeordneten Düsen 7 austretenden Strahlen von Schmiermittelemulsion bezüglich der Rollengruppen 2 und 1.In axial covers 6 of the tool holder 5, nozzles 7 are arranged distributed around the axis of the metal wire 4, which are connected via an annular chamber 8 and a bore 9 in the cover 6 to a lubricant emulsion supply line indicated at 10. The spray directions of the nozzles 7 are aligned with the deformation opening 3 of group 1 or 2 of deformation rollers. The rays of the lubricant emulsion emerging from the nozzles 7 arranged on the left in the drawing can to a large extent pass unhindered between the adjacent deformation rollers 15 of roller group 1 to the next group 2 of deformation rollers 15, which are rotationally offset with respect to roller group 1. The same applies analogously to the jets of lubricant emulsion emerging from the nozzles 7 arranged on the right in the drawing with respect to the roller groups 2 and 1.

Wie die Zeichnung zeigt, sind die vor und die hinter den beiden Gruppen 1, 2 von Verformungsrollen 15 befindlichen Düsen 7 jeweils mit entgegengesetzter Spritzrichtung angeordnet, wobei alle Düsen 7 zur Achse des Metalldrahtes 4 nur wenig geneigt sind.As the drawing shows, the nozzles 7 located in front of and behind the two groups 1, 2 of deformation rollers 15 are each arranged with the opposite spray direction, all nozzles 7 being only slightly inclined to the axis of the metal wire 4.

Der Werkzeughalter 5 mit den Verformungsrollen ist von einem Gehäuse 11 mit beiderseitigen Durchlaßöffnungen für den Metalldraht umgeben. Unterhalb des Werkzeughalters 5 ist ein Auffangbehälter 12 für die Schmiermittelemulsion angeordnet, aus welchem die Emulsion nach Siebung und Filterung wiederum zur Zufuhrleitung 10 gepumpt werden kann.The tool holder 5 with the deformation rollers is surrounded by a housing 11 with through openings for the metal wire on both sides. Arranged below the tool holder 5 is a collecting container 12 for the lubricant emulsion, from which the emulsion can in turn be pumped to the feed line 10 after sieving and filtering.

Knapp außerhalb des Gehäuses 11, anschließend an den Austritt des Metalldrahtes 4 aus den Verformungsrollen (vgl. die mit dem Pfeil bezeichnete Durchlaufrichtung des Drahtes 4) ist die Achse des Metalldrahtes 4 von gegen die Laufrichtung desselben angeordneten Druckluftdüsen 13 mit einer bei 14 angedeuteten Zuführungseinrichtung für Druckluft umgeben. Die Druckluft hält die Schmiermittelemulsion innerhalb des Gehäuses 11 zurück.Just outside the housing 11, subsequent to the exit of the metal wire 4 from the deformation rollers (see the direction of passage of the wire 4 indicated by the arrow), is the axis of the metal wire 4 of compressed air nozzles 13 arranged counter to the direction of travel thereof with a feed device indicated at 14 for Surround compressed air. The compressed air retains the lubricant emulsion within the housing 11.

Die Verformungsrollen 15 der in der Zeichnung dargestellten Vorrichtung sind antriebslos. Der Draht 4 wird durch die Verformungsöffnung 3 mittels einer in der Zeichnung nicht dargestellten Ziehmaschine in bekannter Weise hindurchgezogen. Selbstverständlich ist es aber auch möglich, die Verformungsrollen mit einem Antrieb auszustatten, in welchem Fall dann die Ziehmaschine entfallen kann.The deformation rollers 15 of the device shown in the drawing are driveless. The wire 4 is pulled through the deformation opening 3 by means of a drawing machine, not shown in the drawing, in a known manner. Of course, it is also possible to equip the deformation rollers with a drive, in which case the drawing machine can then be omitted.

Die Verformungsrollen 15 können in bekannter Weise zum Bearbeiten von glattem Draht, oder mit Rillen zum Einwalzen eines Profils in den Draht ausgebildet sein.The deformation rollers 15 can be designed in a known manner for processing smooth wire, or with grooves for rolling a profile into the wire.
