Description

Die Erfindung betrifft zunächst eine Drahtziehvorrichtung mit einer oder mehreren Ziehscheibentrommeln und jeweils einem zugeordneten Ziehscheibentrommel-Antriebsmotor, wobei die Drahtziehvorrichtung ein Maschinengestell aufweist.The invention relates firstly to a wire drawing apparatus having one or more drawing disk drums and in each case one associated drawing disk drum drive motor, wherein the wire drawing apparatus has a machine frame.

Drahtziehvorrichtungen der in Rede stehenden Art sind bekannt, so bspw. aus der nicht vorveröffentlichten deutschen Patentanmeldung mit dem Aktenzeichen DE 102004027716 der Anmelderin, sowie aus der DE 10215456 A1 . Der Inhalt dieser Patentanmeldungen wird hiermit voll inhaltlich in die Offenbarung vorliegender Erfindung mit einbezogen, auch zu dem Zwecke, Merkmale dieser Patentanmeldungen in Ansprüche vorliegender Erfindung mit einzubeziehen.Wire drawing devices of the type in question are known, such as. From the not previously published German patent application with the file number DE 102004027716 the applicant, as well as from the DE 10215456 A1 , The content of these patent applications is hereby incorporated in full in the disclosure of the present invention, also for the purpose of including features of these patent applications in claims of the present invention.

Im Hinblick auf den bekannten Stand der Technik wird zunächst eine technische Problematik der Erfindung darin gesehen, eine Drahtziehvorrichtung der in Rede stehenden Art hinsichtlich einer vereinfachten Fertigung und einer vereinfachten Montage vor Ort verbessert auszugestalten.In view of the known state of the art, a technical problem of the invention is first seen in designing a wire drawing device of the type in question in terms of simplified manufacturing and simplified assembly on site improved.

Diese Problematik ist zunächst und im Wesentlichen durch den Gegenstand des Anspruchs 1 gelöst, wobei darauf abgestellt ist, dass das Maschinengestell unter einer horizontalen Teilung sich aus einem Ziehscheiben-Oberteil mit Zugriffs-Hilfsvorrichtungen, wie Absaugvorrichtung und Ziehsteinaufnahme, zusammensetzt, sowie einem Untergestell, auf welchem das Ziehscheiben-Oberteil aufgesetzt ist. Zufolge dieser erfindungsgemäßen Ausgestaltung ist das Ziehscheiben-Oberteil mit den Zugriffs-Hilfsvorrichtungen als Gesamtteil vorfertigbar und letztlich zum endgültigen Zusammenbau der Drahtziehvorrichtung auf einem Untergestell aufsetz- und mit diesem befestigbar. Das unterhalb der horizontalen Teilung vorgesehene Untergestell trägt bevorzugt keine für den Betrieb der Drahtziehvorrichtung relevanten Vorrichtungsteile. Das Ziehscheiben-Oberteil ist durch die erfindungsgemäße Ausgestaltung modulartig vorzufertigen und bevorzugt vor Ort dem Untergestell zuzuordnen.This problem is first and foremost solved by the subject matter of claim 1, wherein it is based on the fact that the machine frame under a horizontal division is composed of a drawing disc top with access auxiliary devices, such as suction and drawing die, and a base, on which the drawing disc top is placed. According to this embodiment of the invention, the drawing disk top is vorfertigbar with the access auxiliary devices as a whole and ultimately for final assembly of the wire drawing device on a base and put on with this attachable. The provided below the horizontal division base preferably carries no for the operation the wire drawing device relevant device parts. The drawing disc upper part is prefabricated modularly by the inventive design and preferably assigned to the base frame on site.

Die Gegenstände der weiteren Ansprüche sind nachstehend in Bezug zu dem Gegenstand des Anspruchs 1 erläutert, können aber auch in ihrer unabhängigen Formulierung von Bedeutung sein. Es erweist sich hier als günstig, dass in dem Ziehscheiben-Oberteil ein angeflanschter Antriebsmotor für die Ziehscheibentrommel integriert ist, so weiter bevorzugt in Form eines axial unmittelbar angeflanschten Synchronmotors. Eine solche Anordnung ist prinzipiell aus der eingangs erwähnten nicht vorveröffentlichten Patentanmeldung der Anmelderin bekannt, weshalb an dieser Stelle nochmals hierauf Bezug genommen wird. Dieser angeflanschte Antriebsmotor ist im Sinne der Erfindung Teil des Ziehscheiben-Oberteils und somit Teil des modulartig aufgebauten Oberteils der Drahtziehvorrichtung, wenngleich sich der Antriebsmotor nach Anordnung des Oberteils auf dem Untergestell sehr wohl nach unten über die horizontale Trennebene hinaus in das Untergestell erstrecken kann. Das Ziehscheiben-Oberteil weist zudem eine Abdeckhaube auf, zur Überdeckung der Ziehscheibentrommel in Betriebsstellung. In einer vorteilhaften Weiterbildung des Erfindungsgegenstandes ist vorgesehen, dass das Ziehscheiben-Oberteil ein Bedienpult aufweist, über welches die Steuerung bzw. Bedienung der Drahtziehvorrichtung erfolgt. Eine kompakte Bauform der Drahtziehvorrichtung ist dadurch erreicht, dass rückseitig derselben eine unmittelbar mit der Drahtziehvorrichtung verbundene Verschaltungseinheit angeordnet ist. Es bedarf nicht, wie aus dem Stand der Technik bekannt, eines gesonderten Schaltschrankes oder dergleichen. Die Verschaltungseinheit kann hierbei Umrichter und eine Ansteuerelektronik einschließlich eines Frequenzumformers für den Antrieb umfassen. Als besonders vorteilhaft erweist sich hierbei, dass die Verschaltungseinheit unmittelbar an dem Ziehscheiben-Oberteil befestigt ist. So weist erfindungsgemäß das Ziehscheiben-Oberteil neben einer Absaugvorrichtung und der Ziehsteinaufnahme zugleich auch zumindest eine Abdeckhaube und ein Bedienpult und darüber hinaus rückwärtig eine Verschaltungseinheit auf, wobei weiter die Ziehscheibentrommel durch einen in dem Oberteil integriert angeordneten Antriebsmotor unmittelbar angetrieben wird. Das Ziehscheiben-Oberteil ist für sich genommen autark. Das unterhalb der horizontalen Teilung der Drahtziehvorrichtung vorzusehende Untergestell übernimmt lediglich tragende Funktionen. Als bedienungs- und wartungsfreundlich erweist sich noch eine Weiterbildung, bei welcher die Verschaltungseinheit mittels einen Zugriffraum belassenen Trägern an dem Ziehscheiben-Oberteil befestigt ist. Die Verschaltungseinheit ist demzufolge bevorzugt horizontal beabstandet zu dem Ziehscheibentrommelbereich bzw. zu einer den Ziehscheibentrommelbereich rückwärtig abdeckenden Rückwand. Der belassene Zugriffsraum kann durchaus mit abnehmbaren Verkleidungen verschlossen sein. Darüber hinaus kann der Zugriffsraum auch einen Eingriffsraum für die verschwenkte Abdeckhaube bereitstellen.The subjects of the further claims are explained below in relation to the subject matter of claim 1, but may also be significant in their independent formulation. It proves to be advantageous here that in the drawing disc upper part a flanged drive motor for the drawing wheel drum is integrated, so further preferably in the form of an axially directly flanged synchronous motor. Such an arrangement is known in principle from the above-mentioned non-prepublished patent application of the Applicant, which is why at this point once again reference is made. This flanged drive motor is part of the drawing disc top part and thus part of the modular constructed upper part of the wire drawing device, although the drive motor after placement of the upper part on the undercarriage can very well extend down beyond the horizontal parting plane into the base frame. The drawing disc upper part also has a cover, to cover the drawing disc drum in the operating position. In an advantageous development of the subject invention it is provided that the drawing disc upper part has a control panel, via which the control or operation of the wire drawing device takes place. A compact design of the wire drawing device is achieved in that the rear side thereof is arranged a directly connected to the wire drawing device interconnection unit. It is not necessary, as known from the prior art, a separate control cabinet or the like. The interconnection unit can in this case comprise inverters and a control electronics including a frequency converter for the drive. In this case, it proves to be particularly advantageous that the interconnecting unit is fastened directly to the drawing disk upper part. Thus, according to the invention, the drawing disc upper part in addition to a suction device and the drawing tool holder at the same time also at least one cover and a control panel and beyond a rearward interconnection unit, wherein further, the drawing disk drum is directly driven by a drive motor integrated in the upper part arranged. The pulley top is self-sufficient in itself. The below the horizontal division of the wire drawing device to be provided subframe assumes only supporting functions. As a user-friendly and maintenance-friendly yet proves a further development in which the interconnection unit is attached by means of an access space left carriers on the drawing disk top. The interconnection unit is therefore preferably horizontally spaced apart from the drawing disk drum area or at a rear wall covering the draw disk drum area at the rear. The left access space may well be closed with removable panels. In addition, the access space can also provide an engagement space for the tilted cover.

Die Erfindung betrifft des Weiteren eine Drahtziehvorrichtung nach den Merkmalen des Oberbegriffs des Anspruchs 1, wobei die Drahtziehvorrichtung weiter mindestens eine Abdeckhaube aufweist. Um eine Drahtziehvorrichtung der in Rede stehenden Art funktionsvorteilhafter auszubilden, wird vorgeschlagen, dass die Drahtziehvorrichtung mindestens zwei Ziehscheibentrommeln aufweist und dass jeder Ziehscheibentrommel eine Abdeckhaube zugeordnet ist. Dadurch bedingt, dass jeder Ziehscheibentrommel eine Abdeckhaube zugeordnet ist, ist eine verbesserte Abführung des im Umgebungsbereich der jeweiligen Ziehscheibentrommel entstehenden Staubes erreicht. Der beim Drahtziehen entstehende Staub bzw. das anfallende Ziehpulver bleibt örtlich begrenzt in unmittelbarem Bereich der Ziehscheibentrommel und ist somit auch verbessert innerhalb des durch die Abdeckhaube begrenzten Raumes abtransportierbar.The invention further relates to a wire drawing apparatus according to the features of the preamble of claim 1, wherein the wire drawing device further comprises at least one cover. In order to form a wire drawing apparatus of the type in question functionally advantageous, it is proposed that the wire drawing apparatus has at least two drawing disk drums and that each pulling disk drum is assigned a cover hood. Due to the fact that each cover disk drum is assigned a covering hood, improved removal of the dust generated in the surrounding area of the respective drawing disk drum is achieved. The resulting during wire drawing dust or the resulting drawing powder remains localized in the immediate area of the drawing wheel drum and is therefore improved within the limited by the cover space can be removed.

Die Gegenstände der weiteren Ansprüche sind nachstehend in Bezug zu dem Gegenstand des Anspruchs 8 erläutert, können aber auch in ihrer unabhängigen Formulierung von Bedeutung sein. Bevorzugt ist zwischen zwei Abdeckhauben ein Freiraum belassen, wobei in dem Freiraum ein bei geschlossener Abdeckhaube zugängliches Bedienpult angeordnet ist. Bevorzugt ist jeder Ziehscheibentrommel ein Bedienpult zugeordnet, über welches Bedienpult auch bei geschlossener Abdeckhaube Einstellungen der zugeordneten Drahtziehvorrichtungs-Station vorgenommen werden können. Die Bedienpulte sind eindeutig den jeweiligen Ziehscheibentrommeln zugeordnet. Auch ist in dem Freiraum ein bei geschlossener Abdeckhaube zugänglicher Seifenkasten angeordnet. Auch hier ist bevorzugt jeder Ziehscheibentrommel bzw. jeder Station ein Seifenkasten eindeutig zugeordnet. Des Weiteren erweist es sich als vorteilhaft, wenn jeder Abdeckhaube eine gesonderte Staubabsaugung zugeordnet ist, zur Absaugung des in dem durch die Abdeckhaube überfangenen Bereichs anfallenden Ziehpulvers oder dergleichen. Der jeder Ziehscheibentrommel zugeordnete Ziehstein bzw. dessen Ziehsteinhalter ist im Haubenverschlussbereich angeordnet, ist demzufolge bei geschlossener Abdeckhaube von letzterer überdeckt. So verbleibt der Ziehsteinhalter auch bei einer Kontrolle des in dem Freiraum zwischen den beiden geschlossenen Abdeckhauben frei zugänglichen Seifenkastens weiter in einer Geschütztstellung. Hinsichtlich einer verbesserten Kühlwirkung des Ziehsteines kann des Weiteren vorgesehen sein, dass in das, die Ziehsteinhalterung aufnehmende Gehäuse bspw. von oben hineinragend ein Füllteil angeordnet wird, um hierdurch den Freiraum um den Ziehstein und damit den Kühlwasserspalt in vorteilhafter Weise zu verringern.The subjects of the further claims are explained below in relation to the subject matter of claim 8, but may also be significant in their independent formulation. Preferably, a free space is left between two covers, wherein in the free space a control panel accessible when the cover is closed is arranged. Preferably, each drawing disk drum is assigned a control panel, via which control panel settings of the associated wire drawing device station can be made even when the cover is closed. The control panels are clearly assigned to the respective drawing disk drums. Also, in the open space, a soap box accessible when the cover is closed is arranged. Here, too, each soap wheel drum or each station is preferably assigned a soap box unambiguously. Furthermore, it proves to be advantageous if each cover is associated with a separate dust extraction, for the extraction of the overflowed in the area covered by the cover area drawing powder or the like. The each die wheel drum associated die or its die holder is arranged in the hood closure area, is therefore covered with the cover closed by the latter. Thus, the die holder continues to remain in a protected position even when checking the free space in the space between the two closed covers freely accessible soap box. With regard to an improved cooling effect of the die, it can further be provided that in the housing receiving the die holder, for example, a filling member is arranged projecting from above, thereby advantageously reducing the free space around the die and thus the cooling water gap.

Auch betrifft die Erfindung eine Drahtziehvorrichtung nach den Merkmalen des Oberbegriffs des Anspruchs 1, wobei zur verbesserten Absaugung von während des Ziehvorgangs entstehenden Staubes bzw. anfallenden Ziehpulvers vorgeschlagen wird, dass der Ziehscheibentrommel ein zugriffsseitig angeordneter Absaugkanal zugeordnet ist, der die Ziehscheibentrommel um mindestens ein Drittel ihres Umfangs umgibt. Der im Zuge des Drahtziehens von der Ziehscheibentrommel radial abgeschleuderte Staub wird über den zugeordneten Absaugkanal zielsicher abgeführt. Der Absaugkanal ist hierbei fußseitig der Ziehscheibentrommel, diese umfangsmäßig teilweise umfassend ausgeformt, wobei der Absaugkanal mit in Richtung auf die Ziehtrommel weisenden Absaugöffnungen versehen ist.The invention also relates to a wire drawing apparatus according to the features of the preamble of claim 1, wherein it is proposed for improved extraction of dust generated during the drawing operation or drawing powder, that the drawing disk drum is assigned a suction side arranged suction channel, which surrounds the drawing disk drum surrounds at least one third of its circumference. The centrifugally thrown off in the course of wire drawing from the drawing wheel drum dust is dissipated unerring over the associated suction. The suction channel is in this case the foot side of the drawing disk drum, these circumferentially formed partially comprehensive, wherein the suction channel is provided with pointing in the direction of the drawing drum suction.

Die Gegenstände der weiteren Ansprüche sind nachstehend in Bezug zu dem Gegenstand des Anspruchs 13 erläutert, können aber auch in ihrer unabhängigen Formulierung von Bedeutung sein. So erweist es sich als vorteilhaft, wenn der Absaugkanal die Ziehscheibentrommel um mindestens die Hälfte ihres Umfanges umgibt, weiter bevorzugt um etwa 250 - 300° mit Bezug auf die Trommelachse. Bodenseitig weist die Ziehscheibentrommel einen in einem spitzen Winkel zur Vertikalen verlaufenden Schleuderrand auf, mittels welchem eine weitere Verbesserung der Staubabführung in Richtung auf den Absaugkanal erreicht ist. So schließt der Schleuderrand bspw. einen Winkel von 30 bis 75°, bevorzugt 60° zu einer Parallelen der Trommelachse ein, wobei der insgesamt kragenförmige Schleuderrand in Richtung auf die freie Randkante in besagtem spitzen Winkel abfällt. Der Absaugkanal weist des Weiteren eine außenseitige, gewinkelte Wandung auf, wobei die Absaugöffnung im Winkelanschluss ausgebildet ist. Durch die außenseitig gewinkelte Wandung des Absaugkanals ist zunächst zwischen dieser Wandung und dem Schleuderrand der Ziehscheibentrommel eine bevorzugt umlaufende Sammelrinne für Staub oder dergleichen geschaffen, wobei der abgewinkelte Abschnitt der Saugkanalwandung einen spitzen Winkel von etwa 30° zu einer Parallelen der Trommelachse einschließt und ausgehend von einem quer zur Trommelachse ausgerichteten Wandungsabschnitt entgegen der Neigung des Schleuderrandes verläuft. Der Schleuderrand der rotierenden Ziehscheibentrommel geht unter Belassung eines minimalen Ringspaltes über in den feststehenden horizontalen Wandungsabschnitt des Absaugkanals. Bevorzugt ist über den Umfang des Absaugkanals eine Mehrzahl von Absaugöffnungen im Winkelanschluss zwischen dem Horizontalabschnitt und dem abgewinkelten Abschnitt der Wandung vorgesehen, dies weiter bevorzugt bei gleichmäßiger Beabstandung zueinander. Die Winkelwandung weist einen stumpfen Winkel zwischen dem horizontalen Abschnitt und dem abgewinkelten Abschnitt der Kanalwandung auf. Schließlich wird vorgeschlagen, dass die radiale Ausladung des Schleuderrandes einem Fünftel oder mehr des Radius der Ziehscheibentrommel unter Nichtberücksichtigung des Schleuderrandes - dementsprechend gemessen im oberen, schleuderrandfreien Bereich - entspricht. So erstreckt sich der schräg abfallende Schleuderrand mit erheblicher radialer Erstreckung im Vergleich zur Ziehscheibentrommel.The subjects of the further claims are explained below with reference to the subject matter of claim 13, but may also be significant in their independent formulation. Thus, it proves to be advantageous if the suction channel surrounds the drawing disk drum by at least half of its circumference, more preferably by about 250-300 ° with respect to the drum axis. On the bottom side, the drawing disk drum has a spinning edge running at an acute angle to the vertical, by means of which a further improvement of the dust removal in the direction of the suction channel is achieved. Thus, the sling edge includes, for example, an angle of 30 to 75 °, preferably 60 ° to a parallel axis of the drum, wherein the total collar-shaped slinger edge falls in the direction of the free edge in said acute angle. The suction channel further has an outside, angled wall, wherein the suction opening is formed in the angled connection. Through the externally angled wall of the suction channel, a preferably circumferential collecting channel for dust or the like is first created between this wall and the spinning edge of the drawing disk drum, wherein the angled portion of the Saugkanalwandung forms an acute angle of about 30 ° to a parallel axis of the drum and starting from a transverse to the drum axis aligned wall portion opposite to the inclination of the spinning edge runs. The spinning edge of the rotating drawing-disk drum merges into the fixed horizontal wall section of the suction channel leaving a minimal annular gap. It is preferred over the circumference of the suction channel a plurality of suction openings in the angular connection between the horizontal portion and the angled portion of the wall provided, this more preferably with uniform spacing to each other. The angle wall has an obtuse angle between the horizontal portion and the angled portion of the channel wall. Finally, it is proposed that the radial projection of the spinning edge corresponds to one fifth or more of the radius of the drawing disk drum, ignoring the spinning edge - correspondingly measured in the upper, skid-edge-free region. Thus, the obliquely sloping sling edge extends with considerable radial extent in comparison to the drawing wheel drum.

Dargestellt und beschrieben ist zunächst mit Bezug zu Fig. 1 eine Drahtziehvorrichtung 1 in Art einer Geradeausziehmaschine, welche zunächst ein Maschinengestell 2 aufweist. Dieses ist horizontal geteilt, welche Teilung in den Zeichnungen durch die horizontale Linie H dargestellt ist.First, with reference to FIG. 1, a wire drawing apparatus 1 in the form of a straight drawing machine, which first has a machine frame 2, is shown and described. This is divided horizontally, which division is represented by the horizontal line H in the drawings.

Das Maschinengestell 2 setzt sich unter der horizontalen Teilung aus einem Ziehscheiben-Oberteil 3 und einem Untergestell 4 zusammen, auf welch letzterem das Ziehscheiben-Oberteil 3 aufgesetzt ist. Über nicht näher dargestellte Verschraubungen ist das Ziehscheiben-Oberteil 3 mit dem Untergestell 4 verbunden.The machine frame 2 is composed under the horizontal division of a drawing disc upper part 3 and a base frame 4, on which latter the drawing disc upper part 3 is placed. About unillustrated fittings the drawing disc upper part 3 is connected to the base 4.

Das Ziehscheiben-Oberteil 3 weist alle für die Funktion der Vorrichtung notwendigen Bauteile und Zugriffs-Hilfsvorrichtungen auf, während das Untergestell 4 lediglich tragende Funktionen besitzt. So ist das Ziehscheiben-Oberteil 3 mit zwei im Wesentlichen gleichgestalteten Ziehstationen versehen zur abnehmenden Kalibrierung eines Drahtes. Entsprechend sind zwei Ziehscheibentrommeln 5 vorgesehen, welche in Drahtziehrichtung r hintereinander geschaltet angeordnet sind. Hierbei ist jede Ziehscheibentrommel 5 in Drahtziehrichtung r betrachtet geneigt ausgerichtet, dies etwa unter Einschließen eines Neigungswinkels von ca. 15° zur Horizontalen. Entsprechend der die Ziehscheibentrommeln 5 tragenden geneigten Ebene sind auch die jeder Ziehscheibentrommel 5 zugeordneten Seifenkästen 6 und Ziehsteinhalterungen 7 geneigt ausgerichtet.The drawing-disc upper part 3 has all the components and auxiliary access devices necessary for the function of the device, while the undercarriage 4 has only supporting functions. Thus, the drawing disc top 3 is provided with two substantially identically designed drawing stations for decreasing calibration of a wire. Accordingly, two drawing disk drums 5 are provided, which are arranged one behind the other in the direction of wire drawing r. In this case, each drawing disk drum 5 in the direction of wire drawing r is aligned inclined, this about including an inclination angle of about 15 ° to the horizontal. According to the drawing disc drums 5 bearing inclined plane and the each disc pulley 5 associated soap boxes 6 and Ziehsteinhalterungen 7 are inclined.

Jede Ziehscheibentrommel 5 verfügt über einen Antriebsmotor 8. Dieser ist unterhalb des die Ziehscheibentrommel 5 tragenden, geneigt ausgerichteten Maschinenbetts 9 angeordnet. Der Antriebsmotor 8 ist angeflanscht und wirkt unmittelbar auf die zugeordnete Ziehscheibentrommel 5 ein. Der Antriebsmotor 8 versetzt die Ziehscheibentrommel 5 stufenlos in Rotation bzw. bremst diese ab, wobei die Drehung um eine geometrische Achse x-x stattfindet, die senkrecht zum geneigten Maschinenbett 9 ausgerichtet ist.Each drawing disk drum 5 has a drive motor 8. This is arranged below the drawing disk drum 5 bearing, inclined machine bed 9. The drive motor 8 is flanged and acts directly on the associated pulley drum 5 a. The drive motor 8 continuously sets the drawing disk drum 5 in rotation or brakes it, wherein the rotation takes place about a geometric axis xx, which is aligned perpendicular to the inclined machine bed 9.

Die beiden Ziehscheibentrommel-Antriebsmotoren 8 sind als elektrische Synchronmotoren ausgebildet. Sie sind getriebefrei mit der zugeordneten Ziehscheibentrommel 5 verbunden.The two pulley drum drive motors 8 are designed as electrical synchronous motors. They are gearless with the associated pulley drum 5 is connected.

Jede Ziehscheibentrommel 5 ist umgeben durch eine zur Zugriffsseite 10 hin offene Ziehscheiben-Kammer 11. Diese setzt sich im Wesentlichen aus zwei Seitenwandungen 12 und einer Rückwand 13 zusammen, welch letztere der der Zugriffsseite 10 gegenüberliegenden Rückseite 14 der Drahtziehvorrichtung 1 zugeordnet ist. Rückwand 13 und Seitenwandungen 12 sind auf dem die Ziehscheibentrommel 5 tragenden Maschinenbett 9 vertikal ausgerichtet randseitig angeordnet.Each drawing disk drum 5 is surrounded by a pulling disk chamber 11 which is open towards the access side 10. This is essentially composed of two side walls 12 and a rear wall 13, which latter is assigned to the rear side 14 of the wire drawing device 1 opposite the access side 10. Rear wall 13 and side walls 12 are arranged vertically aligned edge on the machine base 9 carrying the drawing disk drum 5.

Die Seitenwandungen 12 sind des Weiteren mit jeweils einer randoffenen Ausnehmung 15 versehen. Diese ist sowohl zur zugriffsseitigen Randkante als auch zur nach oben weisenden Randkante hin geöffnet.The side walls 12 are further provided with a respective open-edged recess 15. This is open both to the access-side edge and to the upward-facing edge.

Die Ziehscheiben-Kammern 11 sind deckelverschließbar, wozu jeder Kammer 11 eine Abdeckhaube 16 zugeordnet ist. Diese ist nahe des oberen Randbereichs der Rückwand 13 schwenkbeweglich um eine raumparallel zur Rückwandfußlinie verlaufende Achse y schwenkbar. Jede Abdeckhaube 16 weist einen Deckenabschnitt 17 und einen der Zugriffsseite 10 zugewandten Stirnwandabschnitt 18 auf. Deckenabschnitt 17 und Stirnwandabschnitt 18 sind hierbei in einem rechten Winkel zueinander angeordnet. In der Verschlussstellung einer jeden Abdeckhaube 16 liegt der Deckenabschnitt 17 auf den nach oben weisenden Randkanten der kammerseitigen Seitenwandungen 12 auf, während der Stirnwandabschnitt 18 wandungsinnenseitig gegen die zugeordneten Stirnflächen der Seitenwandungen 12 sowie des Maschinenbetts 9 tritt. In der Verschlussstellung der Abdeckhaube 16 ist die Ziehscheiben-Kammer 11 mit Ausnahme der seitlichen Ausnehmungen 15 verschlossen.The drawing disk chambers 11 are coverable, to which each chamber 11 is assigned a cover 16. This is pivotable near the upper edge region of the rear wall 13 about an axis y parallel to the rear wall foot line extending axis y. Each cover 16 has a ceiling portion 17 and an access side 10 facing end wall portion 18. Ceiling portion 17 and end wall portion 18 are in this case arranged at a right angle to each other. In the closed position of each cover 16 of the ceiling portion 17 rests on the upwardly facing edges of the chamber-side side walls 12, while the end wall portion 18 enters the inside wall against the associated end faces of the side walls 12 and the machine bed 9. In the closed position the cover 16, the drawing disc chamber 11 is closed except for the lateral recesses 15.

Die beiden Abdeckhauben 16 bzw. die hierdurch zu überdeckenden Ziehscheiben-Kammern 11 sind zu einander beabstandet; belassen entsprechend zwischen sich einen Freiraum 19. In diesem Freiraum 19 ist ein Bedienpult 20 angeordnet, welches auch bei geschlossenen Abdeckhauben 16 zugänglich ist. Dieses Bedienpult 20 dient zur Steuerung der in Drahtziehrichtung r nachgeordneten Ziehscheibe, so bspw. in der Darstellung in Fig. 2 der rechten. Auch die in Drahtziehrichtung r diesem Bedienpult 20 im Freiraum 19 vorgelagerte Ziehscheibentrommel 5 ist über ein weiteres Bedienpult 20', welches gemäß der Darstellung in Fig. 2 linksseitig der Ziehscheibentrommel 5 angeordnet ist, steuerbar. Letzteres ist im Grunde genommen auch in einem zwischen zwei Abdeckhauben 16 belassenen Freiraum 19' angeordnet, sofern dem dargestellten, zwei Ziehscheiben-Stationen aufweisenden Modul ein weiteres gleich ausgestaltetes Modul nebengeordnet wird.The two cover hoods 16 or the drawing disk chambers 11 to be covered thereby are spaced apart from one another; leave correspondingly between them a free space 19. In this space 19, a control panel 20 is arranged, which is accessible even with closed covers 16. This control panel 20 is used to control the downstream in drawing direction r drawing pulley, so for example. In the illustration in Fig. 2 of the right. Also in the direction of wire drawing r this control panel 20 in the free space 19 upstream drawing disk drum 5 is via another control panel 20 ', which is arranged on the left side of the drawing disk drum 5 as shown in Fig. 2, controllable. The latter is basically also arranged in a space left between two covers 16 19 'provided that the illustrated, two pulley stations having module is coordinated with another equal configured module.

Wie aus den Darstellungen zu erkennen, schließt die Abdeckhaube 16 der bspw. in Fig. 2 rechten Ziehscheibentrommel 5 nahezu bündig mit der zugewandten Außenwandung des Maschinengestells 2 ab, während die Abdeckhaube 16 der linken Ziehscheibentrommel 5 zu der zugewandten Außenwandung des Maschinengestells 2 zurückversetzt angeordnet ist, zur Schaffung eines randoffenen Freiraums 19' für das Bedienpult 20'.As can be seen from the illustrations, the cover 16 of the example in Fig. 2 right drawtube drum 5 almost flush with the facing outer wall of the machine frame 2, while the cover 16 of the left pulley drum 5 is set back to the facing outer wall of the machine frame 2 , to create an open-edge space 19 'for the control panel 20'.

Durch den Freiraum 19 bzw. 19' erstreckt sich auch der Seifenkasten 6 der in Drahtziehrichtung r nachgeordneten Ziehscheibentrommel 5, wobei auch dieser Seifenkasten 6 in der Verschlussstellung der Abdeckhauben 16 zur ständigen Kontrolle frei zugänglich ist. Die an dem Seifenkasten 6 über eine Halterung 21 befestigten, in Drahtziehrichtung r vorgelagerten Führungs- und Tastrollen 22 erstrecken sich, die zugewandte Ausnehmung 15 der Kammerseitenwandung 12 durchtretend innerhalb der Ziehscheiben-Kammer 11 der in Drahtziehrichtung r vorgelagerten Ziehscheibentrommel 5.Through the space 19 and 19 'also extends the soap box 6 of the wire drawing direction r downstream drawing disk drum 5, whereby this soap box 6 is freely accessible in the closed position of the covers 16 for constant control. The attached to the soap box 6 via a holder 21, in wire drawing direction r upstream guide and sensing rollers 22 extend, the facing recess 15 of the chamber side wall 12 passing through within the drawing disk chamber 11 of the pulling disk drum 5 upstream in the wire drawing direction r.

Die in Drahtziehrichtung r dem Seifenkasten 6 nachgeordnete Ziehsteinhalterung 7 hingegen ist in einer Verschlussstellung der Abdeckhaube 16 nicht zugänglich; ist dem entsprechend im Haubenverschlussbereich angeordnet.By contrast, the drawing die holder 7 arranged downstream of the soap box 6 in the drawing direction is not accessible in a closing position of the covering hood 16; is accordingly arranged in the hood closure area.

Auf der Rückseite 14 der Drahtziehvorrichtung 1 sind jeder Station zugeordnet unmittelbar an dem Ziehscheiben-Oberteil 3 befestigte Verschaltungseinheiten 23 vorgesehen. Jede Einheit ist in einem Schaltkasten 24 angeordnet, welcher über Träger 25 an dem Ziehscheiben-Oberteil 3 festgelegt ist. Die Träger 25 sind hierbei längenmäßig so bemessen, dass zwischen Schaltkasten 24 und Ziehscheiben-Oberteil 3 ein Zugriffsraum 26 belassen ist. Dieser kann, wenngleich nicht dargestellt, allseitig mittels bevorzugt entfernbarer Wandungen geschlossen sein. Der Zugriffsraum 26 dient auch als Eingriffsraum für Teilabschnitte der aufgeschwenkten Abdeckhaube 16 (vgl. Fig. 3).On the back 14 of the wire drawing device 1 each station assigned directly to the drawing disc upper part 3 attached interconnection units 23 are provided. Each unit is arranged in a control box 24, which is fixed by means of carrier 25 on the drawing disc upper part 3. The carrier 25 are hereby dimensioned in length so that an access space 26 is left between the control box 24 and the drawing disk upper part 3. This may, although not shown, be closed on all sides by means of preferably removable walls. The access space 26 also serves as an engagement space for sections of the swung-cover 16 (see Fig .. 3).

Die Verschaltungseinheit 23 umfasst hierbei u. a. alle Versorgungsleitungen für das Oberteil 3, sowie eine Ansteuerelektronik einschließlich eines Frequenzumformers für den Antrieb.The interconnection unit 23 hereby includes u. a. all supply lines for the upper part 3, as well as a control electronics including a frequency converter for the drive.

Das Ziehscheiben-Oberteil 3 umfasst in dem dargestellten Ausführungsbeispiel im Wesentlichen zwei Ziehscheibentrommeln 5, zwei Seifenkästen 6, zwei Ziehsteinhalterungen 7, zwei unmittelbar auf die Ziehscheibentrommeln einwirkende Antriebsmotoren 8, zwei Ziehscheiben-Kammern 11, zwei Abdeckhauben 16, sowie zwei Bedienpulte 20, zwei Verschaltungseinheiten 23 und zwei jeweils einer Ziehscheibentrommel 5 zugeordnete, nachstehend noch näher beschriebene Staubabsaugungen. Entsprechend weist das Ziehscheiben-Oberteil 3 alle zur Funktion der Drahtziehvorrichtung 1 notwendigen Bauteile bzw. Zugriffs-Hilfsvorrichtungen auf, wobei weiter diese Bauteile bzw. Zugriffs-Hilfsvorrichtungen im Wesentlichen oberhalb der Horizontalteilung des Maschinengestells 2 angeordnet sind. Lediglich die Antriebsmotoren 8 durchgreifen diese Horizontalebene und tauchen in das Untergestell 4 teilweise ein.The drawing disc upper part 3 in the illustrated embodiment essentially comprises two drawing disk drums 5, two soap boxes 6, two drawing stone holders 7, two drive motors 8 acting directly on the drawing disk drums, two drawing disk chambers 11, two covering hoods 16 and two control panels 20, two interconnecting units 23 and two each associated with a drawing disk drum 5, hereinafter described in more detail dust extractors. Accordingly, the drawing disc upper part 3 all necessary for the function of the wire drawing device 1 components or access auxiliary devices, further these components or access auxiliary devices are arranged substantially above the horizontal division of the machine frame 2. Only the drive motors 8 pass through this horizontal plane and dive into the base 4 partially.

Jeder Ziehscheibentrommel 5 ist fußseitig im Bereich der die Trommel umfassenden Ziehscheiben-Kammer 11 ein Absaugkanal 27 zugeordnet. Dieser ist innerhalb des geneigten Maschinenbetts 9 ausgeformt und umgibt die Ziehscheibentrommel 5 um etwa drei Viertel ihres Umfanges. Mit Bezug zu der Draufsicht in Fig. 4 ist ein Ende 28 des ringabschnittförmigen Absaugkanals 27 nahe der Ziehsteinhalterung 7 ausgebildet, von wo aus sich der Absaugkanal 27 weiter mit Bezug auf die Draufsicht in Fig. 4 in Uhrzeigerrichtung um etwa 270° die Ziehscheibentrommel 5 fußseitig umfassend erstreckt. Das andere Ende des Absaugkanals 27 ist mit dem Bezugszeichen 29 versehen. Die in dem Absaugkanal 27 unterdruckerzeugende Gebläseeinheit ist nicht näher dargestellt, ist jedoch auch bevorzugt Bestandteil des Ziehscheiben-Oberteils 3.Each drawing disk drum 5 is assigned a suction channel 27 at the foot in the region of the drawing disk chamber 11 which comprises the drum. This is formed within the inclined machine bed 9 and surrounds the drawing disk drum 5 by about three quarters of its circumference. With reference to the plan view in Fig. 4, an end 28 of the annular portion suction channel 27 is formed near the die holder 7, from where the suction channel 27 further with respect to the plan view in Fig. 4 in the clockwise direction by about 270 °, the die plate drum 5 foot side extends extensively. The other end of the suction channel 27 is provided with the reference numeral 29. The negative pressure in the suction passage 27 blower unit is not shown in detail, but is also preferably part of the drawing disc upper part. 3

Der Absaugkanal 27 besitzt in einem Querschnitt gemäß der Darstellung in Fig. 5 eine nach radial innen, d. h. in Richtung auf die Ziehscheibentrommel 5 weisende gewinkelte Wandung 30. Diese setzt sich zusammen aus einem quer zur Trommelachse x ausgerichteten Bodenabschnitt 31 und einer mit diesem einen stumpfen Winkel von etwa 120° einschließenden Seitenwandung 32.The suction channel 27 has in a cross section as shown in FIG. 5 a radially inward, d. H. This is composed of a transversely to the drum axis x aligned bottom portion 31 and with this an obtuse angle of about 120 ° enclosing side wall 32 in the direction of the pulley drum 5 facing angled wall.

Der Absaugkanal 27 ist zur ringnutförmig die Ziehscheibentrommel 5 fußseitig großteils umgebenden Sammelrinne 33 hin geöffnet, wozu im Winkelanschluss zwischen Bodenabschnitt 31 und Seitenwandung 32 Absaugöffnungen 34 vorgesehen sind. Es ist eine Mehrzahl solcher Absaugöffnungen 34 unter gleichmäßiger Beabstandung über den gesamten Umfang des Absaugkanals 27 vorgesehen (vgl. Fig. 6).The suction channel 27 is open for annular groove the drawing disk drum 5 on the foot side largely surrounding collecting channel 33, for which purpose 32 suction openings 34 are provided in the angle connection between the bottom portion 31 and side wall. A plurality of such suction openings 34 are provided with uniform spacing over the entire circumference of the suction channel 27 (see Fig. 6).

Die Ziehscheibentrommel 5 formt fußseitig eine den Sammelraum 33 nach radial innen begrenzenden Schleuderrand 35 aus. Dieser ist im Bereich eines verdickten Sockelrandes der Trommelwandung 36 ausgebildet, wobei diesem verdickten Sockelabschnitt 37 radial außen ein im Wesentlichen den Schleuderrand 35 ausformender, kragenartiger Schleuderring 38 zugeordnet ist. Dieser Schleuderring 38 ist mittels Schrauben an dem Sockelabschnitt 37 der Ziehscheibentrommel 5 festgelegt.The drawing-disk drum 5 forms on the foot side a centrifugal edge 35 which limits the collecting space 33 radially inward. This is formed in the region of a thickened base edge of the drum wall 36, wherein this thickened base portion 37 radially outwardly a substantially the Schleuderrand 35 ausformender, collar-like slinger 38 is assigned. This slinger 38 is fixed by screws to the base portion 37 of the drawing disk drum 5.

Der Schleuderrand 35 verläuft in einem spitzen Winkel von etwa 60° zu einer Parallelen der Trommelachse x, von der Trommelwandung 36 ausgehend nach radial außen abfallend, bis zu einem freien Ende, welches auf dem Höhenniveau des Bodenabschnitts 31 der gewinkelten Saugkanal-Wandung 30 ausgerichtet ist. Zwischen diesem freien Ende und der Saugkanal-Wandung verbleibt ein die freie Rotation der Ziehscheibentrommel 5 ermöglichender, gering bemessener Ringspalt 39.The slinger edge 35 extends at an acute angle of about 60 ° to a parallel of the drum axis x, starting from the drum wall 36, starting radially sloping down to a free end, which is aligned at the height level of the bottom portion 31 of the angled suction channel wall 30 , Between this free end and the suction channel wall remains a free rotation of the drawing disk drum 5 enabling, small sized annular gap 39th

Die radiale Ausladung a des Schleuderrandes 35 ausgehend von der Trommelwandung 36 entspricht in dem dargestellten Ausführungsbeispiel etwa einem Viertel des Radius b der Ziehscheibentrommel 5 im Bereich der Trommelwandung 36.The radial projection a of the centrifugal edge 35, starting from the drum wall 36, corresponds in the illustrated embodiment to approximately one quarter of the radius b of the drawing disc drum 5 in the region of the drum wall 36.

Durch die Anordnung des vorgeschriebenen Schleuderrandes 35 wird der beim Drahtziehen entstehende Staub bzw. das anfallende Ziehpulver gezielt in Richtung auf die Absaugöffnungen 34 geschleudert, über welche dann saugstromunterstützt der Abtransport erfolgt.Due to the arrangement of the prescribed centrifugal edge 35, the dust or the resulting drawing powder formed during wire drawing is thrown in a targeted manner in the direction of the suction openings 34, via which suction transport then takes place.
