Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Draht­zerkleinerung mit zumindest einem an einem rotierenden Mes­serträger gelagerten, umlaufenden Messer und einem Gegen­werkzeug.The invention relates to a device for wire comminution with at least one rotating knife mounted on a rotating knife carrier and a counter tool.

Eine Vorrichtung zur Drahtzerkleinerung ist aus der EP-B1-0 210 482 bekannt. Die Vorrichtung wird insbesondere verwen­det, um das aus einer Funkenerosionsmaschine austretende Drahtmaterial auf bestimmte Längen abzulängen, um den ein Abfallprodukt darstellenden Draht zu sammeln und einer wei­teren Verarbeitung zuführen zu können. Die bekannte Vor­richtung umfaßt ein mit an seinem Umfang angeordneten Mes­sern versehenes Schneidwerkzeug, welches gegen ein ringför­miges Gegenwerkzeug in Eingriff bringbar ist. Zwischen den beiden Werkzeugen wird der Draht durchgeführt und durch die Einwirkung der Schneidwerkzeuge und des Gegenwerkzeugs ge­quetscht. Dies führt zu einer Verformung des Drahtes und zu einem Abreißen der jeweiligen Draht-Endstücke. Der Nachteil dieser Vorrichtung besteht darin, daß zum einen durch das Quetschen des Drahtes nicht stets auch eine vollständige Abtrennung sichergestellt ist, so daß die einzelnen Draht­stücke aneinander hängenbleiben und daß zum anderen die Ab­trennstellen unregelmäßig ausgebildet sind und einer dichtest möglichen Packung in einem Aufnahmegefäß entgegen­wirken.A device for wire comminution is known from EP-B1-0 210 482. The device is used in particular to cut the wire material emerging from a spark erosion machine to specific lengths, in order to be able to collect the wire, which is a waste product, and to further process it. The known device comprises a cutting tool provided with knives arranged on its circumference, which can be brought into engagement against an annular counter tool. The wire is passed between the two tools and squeezed by the action of the cutting tools and the counter tool. This leads to deformation of the wire and tearing off of the respective wire end pieces. The disadvantage of this device is that on the one hand by the Squeezing the wire does not always ensure complete separation, so that the individual pieces of wire stick together and that, on the other hand, the separation points are irregular and counteract the densest possible packing in a receptacle.

Bei anderen bekannten Erodiermaschinen wird der Draht ohne Zerschneiden in einen Behälter eingeleitet und von Zeit zu Zeit komprimiert. Diese Vorgehensweise erfordert zum einen größere maschinentechnische Ausrüstungen zum Komprimieren des Drahtes und ist zum anderen störanfällig, da eine dichteste Volumenpackung des Drahtes nicht erreicht werden kann und somit Drahtbereiche zu schlaufenartigen Verhängun­gen führen können.In other known eroding machines, the wire is introduced into a container without being cut and compressed from time to time. On the one hand, this procedure requires larger mechanical equipment for compressing the wire and, on the other hand, it is susceptible to faults, since the densest volume packing of the wire cannot be achieved, and wire areas can therefore lead to loop-like hangings.

Die DE-PS 36 31 888 zeigt eine Vorrichtung zum Schneiden von Draht, bei welcher ein erster Messerkörper feststehend angeordnet ist, während ein Gegenmesser hin- und herschwin­gend an einer Durchlauföffnung des Messerkörpers vorbeibe­wegt wird. Bei dieser Vorrichtung werden die jeweils abzu­trennenden Drahtbereiche, bedingt durch die Einwirkung des Gegenmessers verformt, so daß diese nicht in dichtester Packung in einem Aufnahmegefäß aufgefangen werden können. Weiterhin sind, bedingt durch die schwingende Hin- und Her­bewegung des Gegenmessers zwei Schneidrichtungen vorgege­ben, welche zu unterschiedlichen Drahtwurfbahnen führen, so daß die abgeschnittenen Drahtreste durch ein sehr großes Auffanggefäß aufgefangen werden müssen. Weiterhin ist die Schrittgeschwindigkeit, bedingt durch die Masse des Ge­genmessers begrenzt, so daß sich diese Vorrichtung nur bei relativ langsam laufenden Erodiermaschinen einsetzen läßt. Ein weiterer Nachteil liegt darin, daß die Einfädelung des Drahtes nur von Hand erfolgen kann und relativ schwierig ist, da der Draht in der Vorrichtung umgelenkt werden muß.DE-PS 36 31 888 shows a device for cutting wire, in which a first knife body is arranged in a fixed manner, while a counter knife is swung back and forth past a passage opening of the knife body. In this device, the wire areas to be separated are deformed due to the action of the counter knife, so that they cannot be collected in the densest packing in a receptacle. Furthermore, due to the oscillating back and forth movement of the counter knife, two cutting directions are specified, which lead to different wire throwing paths, so that the cut wire remnants have to be collected by a very large collecting vessel. Furthermore, the walking speed is limited due to the mass of the counter knife, so that this device can only be used with relatively slow eroding machines. Another disadvantage is that the wire can only be threaded by hand and is relatively difficult since the wire has to be deflected in the device.

Ein weiterer Nachteil ist durch den relativ großen Ver­schleiß der Schneidkanten des Gegenmessers gegeben, welches sich nicht nachstellen bzw. nachschleifen läßt.Another disadvantage is the relatively large wear on the cutting edges of the counter knife, which cannot be readjusted or reground.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, welche bei einfa­chem Aufbau und einfacher Wirkungsweise eine zuverlässige Zerteilung eines Drahtes ermöglicht, bei welcher die Draht­abschnitte in dichtester Packung oder Lage aufgesammelt werden können und welche an die unterschiedlichsten Draht-­Fördergeschwindigkeiten anpaßbar ist.The invention has for its object to provide a device of the type mentioned, which with a simple structure and a simple mode of operation enables reliable cutting of a wire, in which the wire sections can be collected in the densest packing or position and which are at the most varied wire conveying speeds is customizable.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß das Gegenwerkzeug in Form einer um eine vertikale erste Achse rotierenden, mit einer zentrischen Ausnehmung versehenen Schneidscheibe ausgebildet ist und daß der Messerträger um eine zur ersten Achse parallele zweite Achse rotierend ge­lagert ist und das Messer entlang der Schneidscheibe ge­führt wird.According to the invention, the object is achieved in that the counter tool is designed in the form of a cutting disc rotating about a vertical first axis and provided with a central recess, and in that the knife carrier is mounted in a rotating manner about a second axis parallel to the first axis and the knife is guided along the cutting disc becomes.

Die erfindungsgemäße Vorrichtung zeichnet sich durch eine Reihe erheblicher Vorteile aus. Da das Gegenwerkzeug in Form einer rotierenden Schneidscheibe ausgebildet ist, ist zum einen stets sichergestellt, daß, bedingt durch die Zen­trifugalkraft, der Draht gegen die Außenkante der zentri­schen Ausnehmung angelegt ist, so daß bei einer Einwir­kung des Messers ein saüberer Schnitt erfolgt. Ein weiterer Vorteil der Schneidscheibe ist dadurch gegeben, daß diese an ihrem gesamten Umfang, d.h. dem gesamten Rand der zen­trischen Ausnehmung eine Schneide aufweist, so daß insge­samt der Verschleiß, bedingt durch die große Länge der Schneide, verringert werden kann, so daß sich eine höhere Standzeit der Schneidscheibe ergibt. Da weiterhin der Mes­serträger das Messer entlang der Schneidscheibe führt, ist ein saüberer Schnitt mit einer geraden, exakten Schnitt­ kante möglich, Verquetschungen oder Verbiegungen des Schnittbereichs des Drahtes können vollständig vermieden werden.The device according to the invention is distinguished by a number of considerable advantages. Since the counter tool is designed in the form of a rotating cutting disc, it is always ensured on the one hand that, due to the centrifugal force, the wire is placed against the outer edge of the central recess, so that a cleaner cut is made when the knife acts. Another advantage of the cutting disc is that it has a cutting edge on its entire circumference, ie the entire edge of the central recess, so that overall the wear, due to the large length of the cutting edge, can be reduced, so that a higher one Tool life of the cutting disc results. Since the knife holder continues to guide the knife along the cutting disc, this is a cleaner cut with a straight, exact cut possible edge, squeezing or bending of the cutting area of the wire can be completely avoided.

Die erfindungsgemäße Vorrichtung eignet sich somit zur Ver­wendung bei einer Draht-Erodiermaschine, da es möglich ist, den aus der Maschine austretenden, für den Schnittvorgang verwendeten Draht in kurze Drahtabschnitte zu unterteilen und bei dichtester Packung zwischenzulagern, so daß insge­samt nur ein sehr geringes Volumen eines Lagerungsbehälters erforderlich ist. Ein weiterer Vorteil besteht darin, daß die Austrittsrichtung der Drahtenden vertikal angeordnet ist, so daß diese problemlos in einen Auffangbehälter oder ein Aufnahmegerät eingeleitet werden können. Die Gefahr, daß einzelne Drahtabschnitte in unkontrollierter Weise die Vorrichtung verlassen und außerhalb des Aufnahmegerätes ab­geworfen werden, ist somit vollständig beseitigt.The device according to the invention is thus suitable for use in a wire eroding machine, since it is possible to divide the wire emerging from the machine, used for the cutting process, into short wire sections and to store it in the tightest packing, so that overall only a very small volume of one Storage container is required. Another advantage is that the exit direction of the wire ends is arranged vertically, so that they can be easily introduced into a collecting container or a recording device. The risk of individual wire sections leaving the device in an uncontrolled manner and being dropped outside the recording device is thus completely eliminated.

In einer günstigen Weiterentwicklung der Erfindung ist vor­gesehen, daß der Schneidscheibe eine Umlenkvorrichtung zur Umlenkung eines Drahtes von einer horizontalen in die ver­tikale Förderrichtung vorgeordnet ist. Diese Ausgestal­tungsform ist insbesondere dann günstig, wenn der aus der Erodiermaschine aus laufende Draht in einer horizontalen Richtung die Maschine verläßt, so wie dies bei den bekann­ten Maschinen üblich ist. Zusätzliche Umlenkeinrichtungen o.ä. sind somit nicht erforderlich. Deshalb vereinfacht diese Ausgestaltungsform auch das Einführen eines Drahtes, beispielsweise nach einem Drahtriß in der Erodiermaschine, da der Draht nicht zusätzlich durch spezielle Umlenkmecha­nismen o.ä. geführt werden muß.In a favorable further development of the invention it is provided that the cutting disk is preceded by a deflection device for deflecting a wire from a horizontal into the vertical conveying direction. This embodiment is particularly advantageous when the wire running out of the eroding machine leaves the machine in a horizontal direction, as is customary in the known machines. Additional deflection devices or similar are therefore not necessary. Therefore, this embodiment also simplifies the insertion of a wire, for example after a wire tear in the eroding machine, since the wire is not additionally created by special deflection mechanisms or the like. must be performed.

Weiterhin ist es erfindungsgemäß vorteilhaft, wenn die Um­lenkvorrichtung in Form eines Bandförderers ausgebildet ist, da der Bandförderer zum einen einfach aufgebaut und leicht bedienbar ist und zum anderen eine sichere Führung des Drahtes gewährleistet. Weiterhin kann das Einlegen des Drahtes auf besonders einfache Weise erfolgen.Furthermore, it is advantageous according to the invention if the deflection device is designed in the form of a belt conveyor, since the belt conveyor is simple in structure and is easy to use and, on the other hand, ensures secure guidance of the wire. Furthermore, the wire can be inserted in a particularly simple manner.

Um einen sicheren Einlauf des Drahtes in die Umlenkvor­richtung sicherzustellen, erweist es sich als günstig, wenn, bezogen auf die Förderrichtung des Drahtes, vor der Umlenkvorrichtung eine Trichterführung angeordnet ist. Die Trichterführung kann bevorzugterweise mit einem Drahtsensor versehen sein, um sicherzustellen, daß die Vorrichtung zur Drahtzerkleinerung nur dann in Betrieb gesetzt wird, wenn sie von einem Erodierdraht durchlaufen wird.In order to ensure a safe entry of the wire into the deflection device, it has proven to be advantageous if, based on the direction of conveyance of the wire, a funnel guide is arranged in front of the deflection device. The funnel guide can preferably be provided with a wire sensor in order to ensure that the device for wire comminution is only put into operation when an eroding wire passes through it.

Die erfindungsgemäße Vorrichtung eignet sich in besonders günstiger Weise zu einer einfachen Steuerung und Anpassung an die jeweilige Draht-Fördergeschwindigkeit der Erodierma­schine. So ist es erfindungsgemäß möglich, eine erste An­triebseinrichtung für die Umlenkvorrichtung und eine zweite Antriebseinrichtung für den Messerkörper und die Schneid­scheibe in Abhängigkeit von den Signalen des Drahtsensors oder in Abhängigkeit von einer durch die Umlenkvorrichtung ermittelten Zugkraft zu steuern. Die erfindungsgemäße Vor­richtung ist somit sehr variabel an die jeweiligen Be­triebsbedingungen anpaßbar. Hinsichtlich einer Zugkraftre­gelung ist es beispielsweise möglich, die Betriebsgeschwindigkeit der Vorrichtung über eine Stromregelung der Antriebsmotoren einzustellen.The device according to the invention is particularly advantageously suitable for simple control and adaptation to the respective wire conveying speed of the eroding machine. It is thus possible according to the invention to control a first drive device for the deflection device and a second drive device for the knife body and the cutting disc as a function of the signals from the wire sensor or as a function of a tensile force determined by the deflection device. The device according to the invention can thus be adapted very variably to the respective operating conditions. With regard to traction control, it is possible, for example, to set the operating speed of the device via current control of the drive motors.

Der Drahtsensor, welcher der Umlenkvorrichtung vorge­schaltet ist, kann beispielsweise als Näherungssensor aus­gebildet sein, um die Annäherung eines Drahtelementes fest­zustellen, so daß die erfindungsgemäße Vorrichtung bei ei­nem Drahtriß o.ä. abgeschaltet werden kann. Weiterhin er­folgt automatisch ein Einschalten der Vorrichtung, wenn ein Draht eingelegt werden soll.The wire sensor, which is connected upstream of the deflection device, can be designed, for example, as a proximity sensor in order to determine the approach of a wire element, so that the device according to the invention in the event of a wire break or the like. can be switched off. Furthermore, the device is switched on automatically when a wire is to be inserted.

Um eine funktionssichere Bewegung der Messer sicherzu­stellen, erweist es sich als günstig, wenn der Messerträger mit zumindest einem Arm versehen ist, an dessen Endbereich das Messer angeordnet ist. Es wird somit vermieden, daß die abgeschnittenen Drahtstücke gegen zentrische Bereiche des Messerträgers geworfen werden und an diesen hängenbleiben.In order to ensure a functionally reliable movement of the knives, it has proven to be advantageous if the knife holder is provided with at least one arm, at the end region of which the knife is arranged. It is thus avoided that the cut wire pieces are thrown against central areas of the knife carrier and get caught on it.

In einer besonders günstigen Ausgestaltung der Erfindung ist vorgesehen, daß der Messerträger vier kreuzförmig ange­ordnete Arme mit jeweils einem Messer umfaßt, so daß insge­samt die Drehgeschwindigkeit des Messerträgers verringert werden kann, da mehrere Arme pro Umdrehung mit der Schneid­scheibe in Eingriff bringbar sind.In a particularly advantageous embodiment of the invention it is provided that the knife carrier comprises four arms arranged in a cross shape, each with a knife, so that the overall speed of rotation of the knife carrier can be reduced, since several arms can be brought into engagement with the cutting disk per revolution.

Um eine Überführung des Drahtes von der Umlenkvorrichtung in die Schneidscheibe zu vereinfachen, kann es sich als günstig erweisen, wenn zwischen der Umlenkvorrichtung und der Schneidscheibe ein mit der Schneidscheibe drehbares Führungselement angeordnet ist, welches eine trlchterför­mige Ausnehmung aufweisen kann.In order to simplify a transfer of the wire from the deflection device into the cutting disk, it can prove to be advantageous if a guide element which can rotate with the cutting disk and which can have a funnel-shaped recess is arranged between the deflection device and the cutting disk.

Da das von der Erodiermaschine abgeführte Drahtmaterial üb­licherweise nicht spannungsfrei ist, ist es besonders gün­stig, wenn die Vorrichtung gegenüber Masse elektrisch iso­liert ausgebildet ist, so daß Erodiervorgänge an den Schneidwerkzeugen vermieden werden können. Vorteilhaft sind die Drahtführungsteile der Vorrichtung elektrisch isoliert.Since the wire material discharged from the eroding machine is usually not stress-free, it is particularly advantageous if the device is designed to be electrically insulated from the ground, so that eroding processes on the cutting tools can be avoided. The wire guide parts of the device are advantageously electrically insulated.

Weiterhin ist es günstig, dem Messerträger ein mit einem Rüttler versehenes Aufnahmegerät nachzuordnen, um die auf­gefangenen abgeschnittenen Drahtenden in dichtest möglicher Weise zu lagern.Furthermore, it is advantageous to arrange a pick-up device provided with a vibrator after the knife carrier in order to store the cut-off wire ends in the densest possible manner.

Anliegend wird die Erfindung anhand eines Ausführungs­beispiels in Verbindung mit der Zeichnung beschrieben. Da­bei zeigt:

  • Fig. 1 eine Seitenansicht der erfindungsgemäßen Vor­richtung,
  • Fig. 2 eine Detail-Seitenansicht, teils im Schnitt, der in Fig. 1 gezeigten Anordnung,
  • Fig. 3 eine Schnittansicht entlang der Linie III/III von Fig. 2,
  • Fig. 4 eine Rückansicht der erfindungsgemäßen Vor­richtung und
  • Fig. 5 eine Unteransicht der Vorrichtung mit Blick auf den Messerträger und die Schneidscheibe.
The invention is described with reference to an embodiment in connection with the drawing. It shows:
  • 1 is a side view of the device according to the invention,
  • 2 is a detailed side view, partly in section, of the arrangement shown in FIG. 1,
  • 3 is a sectional view taken along the line III / III of FIG. 2,
  • Fig. 4 is a rear view of the device according to the invention and
  • Fig. 5 is a bottom view of the device with a view of the knife carrier and the cutting disc.

Erfindungsgemäß umfaßt die Vorrichtung ein Gehäuse 16 oder einen Träger, an welchem an der Unterseite ein Messerträger 1 drehbar gelagert ist, an welchem mehrere Messer 2 befe­stigt sind. Bei dem gezeigten Ausführungsbeispiel umfaßt der Messerträger 1 insgesamt vier Messer 2, welche an den Enden von vier kreuzförmigen Armen 12 gelagert sind.According to the invention, the device comprises a housing 16 or a carrier on which a knife carrier 1 is rotatably mounted on the underside, to which a plurality of knives 2 are fastened. In the embodiment shown, the knife carrier 1 comprises a total of four knives 2, which are supported at the ends of four cross-shaped arms 12.

Der Messerträger 1 ist um eine zweite vertikale Achse 6 drehbar an dem Gehäuse 16 angebracht. Ebenfalls an der Un­terseite oder dem unteren Bereich des Gehäuses 16 ist eine mit einer zentrischen Ausnehmung 5 versehene Schneidscheibe 3 drehbar gelagert, wobei die Schneidscheibe 3 um eine er­ste vertikale Achse 4 drehbar oder rotierbar ist. Die bei­den Achsen 4 und 6 sind zueinander parallel und in einem Abstand angeordnet, so wie dies beispielsweise aus Fig. 5 ersichtlich ist. Bei einer Drehung des Messerträgers 1 überstreicht somit das Messer 2 die Unterseite der Schneid­scheibe 3, so daß ein durch die zentrische Ausnehmung 5 durchtretendes Drahtmaterial abgetrennt wird. Da die zen­trische Ausnehmung 5 von der Unterseite her frei zugänglich ist, können die abgeteilten Drahtenden problemlos nach un­ ten herausfallen, um in einem mit einem Rüttler 15 verse­henen Aufnahmegerät 14 aufgefangen zu werden (siehe Fig. 1).The knife carrier 1 is attached to the housing 16 so as to be rotatable about a second vertical axis 6. Also on the underside or the lower region of the housing 16, a cutting disk 3 provided with a central recess 5 is rotatably mounted, the cutting disk 3 being rotatable or rotatable about a first vertical axis 4. The two axes 4 and 6 are arranged parallel to one another and at a distance, as can be seen, for example, from FIG. 5. When the knife carrier 1 rotates, the knife 2 thus sweeps over the underside of the cutting disk 3, so that a wire material passing through the central recess 5 is cut off. Since the central recess 5 is freely accessible from the underside, the divided wire ends can easily be moved to un ten fall out to be caught in a recording device 14 provided with a vibrator 15 (see FIG. 1).

Die parallele Anordnung der beiden vertikalen Achsen 4, 6 ist insbesondere aus Fig. 3 zu ersehen, wobei sich aus der Darstellung gemäß Fig. 3 weiterhin ergibt, daß die Schneid­scheibe 3 und der Messerträger 1 mittels eines Antriebsrie­mens 17 oder einer geeigneten Antriebseinrichtung bewe­gungsmäßig miteinander gekoppelt sind. Der Antrieb des Mes­serträgers 1 erfolgt über eine zweite Antriebseinrichtung 11, welche mit dem Messerträger 1 über eine Welle 18 ver­bunden ist.The parallel arrangement of the two vertical axes 4, 6 can be seen in particular from FIG. 3, it also being apparent from the illustration according to FIG. 3 that the cutting disk 3 and the knife carrier 1 are coupled to one another in terms of movement by means of a drive belt 17 or a suitable drive device are. The knife holder 1 is driven by a second drive device 11 which is connected to the knife holder 1 by a shaft 18.

Wie aus der Abbildung gemäß Fig. 3 ersichtlich ist, weist die Schneidscheibe 3 an ihrem unteren Bereich eine ballige oder konvexe Form auf, welche ein Übergleiten des Messers 2 erleichtert.As can be seen from the illustration according to FIG. 3, the cutting disc 3 has a spherical or convex shape at its lower region, which facilitates sliding of the knife 2.

Die Messer 2 können an dem Messerträger 1 einjustierbar oder verstellbar angeordnet sein, um einen Verschleiß aus­gleichen zu können.The knives 2 can be arranged on the knife carrier 1 in an adjustable or adjustable manner in order to be able to compensate for wear.

Bei dem gezeigten Ausführungsbeispiel ist die Schneid­scheibe 3 einstückig mit einem Führungselement 13 ver­bunden, welches mit einer trichterförmigen Ausnehmung ver­sehen ist, welche, wie in Fig. 2 dargestellt, ein Einführen des Drahtmaterials erleichtert.In the exemplary embodiment shown, the cutting disc 3 is integrally connected to a guide element 13, which is provided with a funnel-shaped recess, which, as shown in FIG. 2, facilitates insertion of the wire material.

Die erfindungsgemäße Vorrichtung umfaßt weiterhin eine Um­lenkvorrichtung 7, welche eine Antriebsrolle 19 umfaßt, welche über eine erste Antriebseinrichtung 10 antreibbar ist. Aus der Darstellung gemäß Fig. 3 ergibt sich, daß die Antriebsrolle 19 zu diesem Zwecke mit einer Welle 22 ver­bunden ist, die in geeigneter Weise mit der Antriebsein­richtung 10 in Betriebsverbindung steht. Weiterhin ist eine Andruckrolle 20 sowie eine Laufrolle 21 vorgesehen. Die Laufrolle 21 und die Antriebsrolle 19 werden von einem Band 23 umschlungen, welches am Außenumfang der Andruckrolle 20 geführt ist und mittels einer Spannrolle 24 spannbar ist. 51m Bereich zwischen der Laufrolle 21 und der Andruckrolle ist eine Trichterführung 8 vorgesehen, durch welche das Drahtmaterial zwischen die Andruckrolle 20 und das Band 23 einlegbar ist.The device according to the invention further comprises a deflection device 7 which comprises a drive roller 19 which can be driven via a first drive device 10. 3 that the drive roller 19 is connected for this purpose to a shaft 22, which is in a suitable manner with the drive device 10 in operative connection. Furthermore, one Pressure roller 20 and a roller 21 are provided. The roller 21 and the drive roller 19 are wrapped in a band 23 which is guided on the outer circumference of the pressure roller 20 and can be tensioned by means of a tension roller 24. A funnel guide 8 is provided in the area between the roller 21 and the pressure roller, through which the wire material can be inserted between the pressure roller 20 and the belt 23.

Im Bereich der Trichterführung 8 ist weiterhin ein Draht­sensor 9 vorgesehen, welcher mittels eines Klemmstocks 25 an der Trichterführung 8 gehaltert ist. Mittels des Draht­sensors 9 ist es möglich, festzustellen, ob die Trichter­führung 8 von einem Draht durchlaufen wird.In the area of the funnel guide 8, a wire sensor 9 is also provided, which is held on the funnel guide 8 by means of a clamp 25. By means of the wire sensor 9 it is possible to determine whether the funnel guide 8 is traversed by a wire.

Die Umlenkvorrichtung 7 dient dazu, das horizontal an­geförderte Drahtmaterial in eine vertikale Richtung um­zulenken.The deflection device 7 serves to deflect the horizontally conveyed wire material in a vertical direction.

Bei dem erfindungsgemäßen Ausführungsbeispiel ist es mög­lich, die Messergeschwindigkeit so einzustellen, daß stets Drahtstücke mit konstanter Drahtlänge geschnitten werden. Die Anpassung kann an die durch die Umlenkeinrichtung er­mittelte Zugkraft o.ä. gekoppelt sein, so daß stets eine entsprechende Zuordnung vorliegt. Das Ein- und Ausschalten der Vorrichtung erfolgt entweder unter Verwendung des Drahtsensors 9 oder unter Verwendung der durch die Umlenk­vorrichtung 7 ermittelten Zugspannung des Erodierdrahtes. Die erfindungsgemäße Vorrichtung schaltet sich somit auto­matisch beim Stillstand der Erosionsmaschine aus und wird bei deren Einschalten automatisch in Betrieb gesetzt. Der Drahtsensor 9 dient insbesondere dazu, einen Drahtriß festzustellen, da der Sensor als Näherungssensor ausgebil­det ist, welcher eine Anlage des Drahtes an die Wandung des Trichters der Trichterführung 8 feststellt.In the embodiment according to the invention it is possible to set the knife speed so that wire pieces with a constant wire length are always cut. The adaptation can be made to the tensile force or the like determined by the deflection device. be coupled so that there is always a corresponding assignment. The device is switched on and off either using the wire sensor 9 or using the tension of the erosion wire determined by the deflection device 7. The device according to the invention thus switches off automatically when the erosion machine is at a standstill and is automatically put into operation when it is switched on. The wire sensor 9 is used in particular to detect a wire break, since the sensor is designed as a proximity sensor, which detects that the wire abuts the wall of the funnel of the funnel guide 8.

Die erfindungsgemäße Vorrichtung ist so ausgebildet, daß keine Drahtreste in der Vorrichtung verbleiben können, ins­besondere nicht bei einem Drahtriß. Ein weiterer Vorteil der Vorrichtung ist dadurch gegeben, daß die Drahtlängen unabhängig von der Durchlaufgeschwindigkeit der Erodierma­schine eingestellt und konstant aufrechterhalten werden können, da die Drehgeschwindigkeit des Messerträgers 1 und der Schneidscheibe 3 unabhängig von der Fördergeschwindig­keit der Umlenkvorrichtung 7 sind.The device according to the invention is designed so that no wire remnants can remain in the device, especially not in the event of a wire break. Another advantage of the device is that the wire lengths can be set and maintained independently of the throughput speed of the eroding machine, since the rotational speed of the knife carrier 1 and the cutting disc 3 are independent of the conveying speed of the deflection device 7.

Durch die zentrische Ausnehmung 5 und die an dieser ver­wirklichte Schneidkante ist sichergestellt, daß das Ab­schneiden der Drahtstücke stets rechtwinklig in einer sau­beren Schnittlinie erfolgt. Quetschungen o.ä. sind somit ausgeschlossen.The central recess 5 and the cutting edge realized on this ensures that the cutting off of the wire pieces is always carried out at right angles in a clean cutting line. Bruises or similar are therefore excluded.

Die erfindungsgemäße Umlenkvorrichtung ermöglicht es wei­terhin, die Vorrichtung bei einem Stillstand der Erosions­maschine anzuhalten, ohne daß hierdurch die Spannung des Drahtes beeinflußt würde. Weiterhin ist es möglich, den Draht auf besonders einfache Weise in die Vorrichtung ein­zuführen, so daß insbesondere beim Neubeschicken der Erosi­onsmaschine umständliche manuelle Einstellungen entfallen können.The deflection device according to the invention also makes it possible to stop the device when the erosion machine is at a standstill without the wire tension being influenced thereby. Furthermore, it is possible to insert the wire into the device in a particularly simple manner, so that laborious manual adjustments can be dispensed with, in particular when the erosion machine is reloaded.

Die einfache Konstruktion der erfindungsgemäßen Vorrichtung ermöglicht eine Verwendung bei unterschiedlichsten Ausge­staltungsformen von Draht-Erodiermaschinen, so daß eine universelle Anwendbarkeit hergestellt ist.The simple construction of the device according to the invention enables use in the most varied configurations of wire EDM machines, so that a universal applicability is established.
