Abstract

A multiple die wire drawing bench has draw rollers (3,7) mounted on coaxial shafts (2,6) with each shaft driven by a gear wheel (11,12). The draw roller (3) mounted on the hollow shaft (2) has two different external diameters (4,5) to provide different tangential forces to suit the size of wire being drawn. The draw roller (7) has three such diameters (8-10). By mounting the rollers (3,7) on shafts with separate drives the minimum diameter (8) of the roller (7) is not unduly small. It thus is not subject to a high rate of wear, as is the case with single shaft draw rollers.

Description

Titel der ErfindungTitle of the invention

Mehrfachdraht ziehmaschine Anwendungsgebiet der Erfindung Die Erfindung findet Anwendung in Drahtziehereien, insbesondere bei gleitend arbeitenden Mehrfachdrahtziehmaschinen.Multiple wire drawing machine Field of application of the invention The invention is used in wire drawing shops, especially in sliding multiple wire drawing machines.

Charakteristik der bekannten technischen Lösungen Gleitend arbeitende Mehrfachdrahtziehmascbinen sind bekannt.Characteristics of the known technical solutions Sliding working Multiple wire drawing machines are known.

Sie sind vorteilhafterweise mit sogenannten Ziehkonen ausgerüstet, wodurch die Anzahl der Ziehwellen, auf denen die Ziehkonen befestigt sind, vergleichsweise geringer gehalten werden kann als bei gleitend arbeitenden Mehrfachdrahtziehmaschinen mit Einzelziehscheiben gleichen Durchmessers0 Zehrfachdrahtziehmaschinen, die mit Ziehkonen ausgerüstet sind, können demzufolge kostengünstiger hergestellt werden.They are advantageously equipped with so-called drawing cones, whereby the number of drawing shafts on which the drawing cones are attached is comparative can be kept lower than with sliding multiple wire drawing machines with single drawing disks of the same diameter Draw cones are equipped, can therefore be manufactured more cost-effectively.

Als besonders nachteilig sind jedoch die sehr unterschiedlichen Ziehringdurchmesser auf einem Ziehkonus zu betrachten.However, the very different drawing ring diameters are particularly disadvantageous to look at on a drawing cone.

Diese Durchmesserunterschiede sind bedingt durch den Umformvorgang des Drahtes, da jede Umformstufe eine Längung des Drahtes ergibt, die sich von Ziehstufe zu ZiehstuSe vergrößere. Hieraus folgt, daß der starke, in die Ziehmaschine einlaufende Draht au9 den kleinsten Ziehringdurchmesser geführt werden muß. Die durch den kleinen Ziehringdurchmesser bedingte starke Krümmung des Drahtes führt zu einer starken Belastung des Drahtes und unter Umständen zu Drahtbrüchen, Weiterhin werden durch das verfahrensbedingte Gleiten des Drahtes auf den Ziehkonen die kleinen Ziehringdurchmesser die die größten Ziehkräfte zu übertragen haben, folglich auch den größten Reibungskräften ausgesetzt sind, vom Verschleiß am stärksten betroffen.These differences in diameter are due to the forming process of the wire, as each forming stage results in an elongation of the wire that results from the drawing stage to enlarge the drawing nozzle. From this it follows that the strong one entering the drawing machine Wire must be guided through the smallest drawing ring diameter. The one by the little one The strong curvature of the wire due to the diameter of the drawing ring leads to a strong curvature Stress on the wire and possibly wire breaks, continue to be through the process-related sliding of the wire on the drawing cones the small drawing ring diameter the have to transmit the greatest pulling forces, consequently also the greatest frictional forces are most exposed to wear and tear.

Ziel der Erfindung Es ist Ziel der ErSindung, den Verschleiß an den Ziehringen zu mindern.Object of the invention It is the aim of the invention to reduce the wear and tear on the To reduce draw rings.

Darlegung des Wesens der Erfindung Der Erfindung liegt die Aufgabe zugrunde, bei gleitend arbeitenden Mehrfachdrahtziehmaschinen, die mit Ziehkonen arbeiten, den kleinsten Ziehringdurchmesser zu vergrößern, ohne daß der größte Ziehringdurchmesser ebenfalls vergrößert zu werden braucht.Statement of the essence of the invention The object of the invention is to be found based on sliding multiple wire drawing machines with drawing cones work to enlarge the smallest drawing ring diameter without reducing the largest drawing ring diameter also needs to be enlarged.

Erfindungsgemäß wird diese Aufgabe gelöst durch einen geteilten Ziehkonus, dessen hintere am Maschinengehäuse liegenden Ziehringe auf einer Hohlwelle und die vorderen Ziehringe auf einer die Hohlwelle durchdringenden Ziehwelle angeordnet sind, wobei Hohlwelle und Ziehwelle antriebsseitig Maschinenelemente, vorzugsweise Zahnräder, aufweisen, die unterschiedliche Drehzahlen gewährleisten.According to the invention, this object is achieved by a divided drawing cone, its rear on the machine housing pull rings on a hollow shaft and the front pull rings arranged on a pull shaft penetrating the hollow shaft are, with the hollow shaft and pulling shaft on the drive side machine elements, preferably Have gears that ensure different speeds.

Es gehört auch zur ErSindung, daß vorteilhafterweise mindestens zwei Ziehringe au9 dem hinteren Teil des Ziehkonus angeordnet sind.It is also part of the invention that advantageously at least two Draw rings are arranged on the rear part of the draw cone.

Weiterhin gehört zur Erfindung, daß beispielsweise nur das erste von mehreren innerhalb einer Mehrfachdrahtziehmaschine angeordneten Ziehkonuspaaren nach der Erfindung geteilt ausgeführt ist.The invention also includes that, for example, only the first of several drawing cone pairs arranged within a multiple wire drawing machine is carried out divided according to the invention.

Zur Erfindung gehört auch, daß insbesondere der einlauSseitige Ziehring groß gehalten und Differenzen in den UmMangsgeschwindigkeiten der Ziehringe antriebsseitig beispielsweise durch entsprechend dimensionierte Maschinenelemente, wie Zahnräder, abgleichbar sind.The invention also includes, in particular, the drawing ring on the inlet side kept large and differences in the circumferential speeds of the pull rings on the drive side for example through appropriately dimensioned machine elements such as gears, are adjustable.

Ausführungsbeispiel Die ErSindung wird anhand der beiliegenden Zeichnungen beispielhaft erläutert. Es zeigen: Fig0 1 ein Schnitt des geteilten Ziehkonus Figo 2 Anordnung der geteilten Ziehkonen innerhalb der Mehrfachdrahtziehmaschine Bigo 3 eine Kombination geteilter und ungeteilter Ziehkonen Fig. 4 Anordnung der Ziehwellenachsen in unterschiedlichen Ebenen.Embodiment The invention is based on the accompanying drawings explained by way of example. Shown are: Fig0 1 a section of the divided drawing cone Figo 2 Arrangement of the divided drawing cones within the Bigo multiple wire drawing machine 3 a combination of divided and undivided drawing cones. FIG. 4 arrangement of the drawing shaft axes in different levels.

Im Maschinengehäuse 1 ist eine Hohlwelle 2 gelagert. Auf dieser Hohlwelle 2 ist ein Ziehkonus 3, bestehend aus den Ziehringen 4 und 5, befestigt. Innerhalb der Hohlwelle 2 ist eine Ziehwelle 6 gelagert. Auf dieser Ziehwelle 6 ist koaxial zum Ziehkonus 3 der Ziehkonus 7 mit den Ziehringen 8, 9, 10 gelagert.A hollow shaft 2 is mounted in the machine housing 1. On this hollow shaft 2, a drawing cone 3, consisting of the drawing rings 4 and 5, is attached. Within a pull shaft 6 is mounted on the hollow shaft 2. On this pull shaft 6 is coaxial to the drawing cone 3 of the drawing cone 7 with the drawing rings 8, 9, 10 mounted.

Die Hohlwelle 2 und die Ziehwelle 6 tragen antriebsseitig Maschinenelemente, beispielseise Zahnräder 11 und 12, zur Einleitung von Drehmomenten. Die Hohlwelle 2, die Ziehwelle 6, die Zahnräder 11 und 12 sowie die Ziehringe 4, 5, 8, 9, 10 bilden eine Zieheinheit 13. Es ist auch möglich, und je nachdem für wieviel Züge eine Mehrfachdrahtziehmaschine ausgestattet ist, erforderlich, daß der Ziehkonus 3 aus mehr als zwei und der Ziehkonus 7 aus weniger als drei oder auch aus mehr als drei Ziehringen besteht.The hollow shaft 2 and the pulling shaft 6 carry machine elements on the drive side, For example, gears 11 and 12, for the introduction of torques. The hollow shaft 2, the pulling shaft 6, the gears 11 and 12 and the pulling rings 4, 5, 8, 9, 10 form a drawing unit 13. It is also possible, and depending on how many draws, a multiple wire drawing machine is equipped, it is necessary that the drawing cone 3 consists of more than two and the drawing cone 7 consists of fewer than three or more than three pull rings.

Diese Zieheinheiten 13 sind paarweise im Maschinengehäuse 1 der Mehrfachdrahtziehmaschine angeordnet. Zwischen zwei Zieheinheiten 13 ist der Ziehsteinhalter 14 befestigt. In einer Mehrfachdrahtziehmaschine können nun, wie in Figo 2 dargestellt, eine gerade Anzahl von Zieheinheiten 13 in einer Ebene nebeneinander oder paarweise in zwei Ebenen übereinander gem.These drawing units 13 are in pairs in the machine housing 1 of the multiple wire drawing machine arranged. The drawing die holder 14 is fastened between two drawing units 13. In a multiple wire drawing machine, as shown in FIG Number of pulling units 13 in a plane next to each other or in pairs in two Levels one above the other according to

Figo 4 angeordnet sein. Beim Ziehen feiner Fertigdrähte ist es nicht unbedingt erforderlich, daß, in Ziehrichtung gesehen, das zweite Paar Zieheinheiten 13 auch als geteilter Ziehkonus 3, 5 ausgebildet ist, da infolge der kleinen Drahtdurchmesser und der damit verbundenen kleinen Ziehkräfte die betreffenden Ziehringe nicht so hoch belastet werden wie am Drahteinlauf. Demzufolge kann dann das zweite Paar Zieheinheiten 13 aus konventionellen Ziehkonen 15 gern. Fig. 3 bestehen. Durch diese erfindungsgemäße Lösung ist es möglich, die am stärksten belasteten einlaufseitigen Ziehringe 4 5 im Durchmesser größer zu gestalten, ohne den größten Ziehring 10 ebenfalls vergrößern zu müssen0 Die sich ergebenden Längendifferenzen des Drahtes werden durch entsprechende Dimensionierung der Maschinenelemente (Zahnräder 11 und 12) kompensiert.Figo 4 be arranged. When drawing fine finished wires, it is not It is imperative that, seen in the direction of drawing, the second pair of drawing units 13 is also designed as a split drawing cone 3, 5 because of the small wire diameter and the associated small pulling forces do not affect the pull rings in question are heavily loaded as at the wire inlet. As a result, the second pair of pulling units 13 from conventional drawing cones 15 like. Fig. 3 consist. By this solution according to the invention, it is possible for the most heavily loaded inlet side To make drawing rings 4 5 larger in diameter, without the largest drawing ring 10 as well to have to increase0 The resulting differences in length of the wire are due to corresponding dimensioning of the machine elements (gears 11 and 12) compensated.
