Abstract

In a guiding arm for a wire bobbin winder (1) provided with wire guiding rollers wherein the roller guiding is curved according to a spatial curve and including a plurality of profiled rollers (4) arranged on the guiding arm (1), multiple utilizations and a prolonged life duration are achieved by arranging the rollers (4) one by one and spaced from each other on the convex side of the spatial curve where said curve has its most pronounced curvature. The guiding arm (1) is preferably embodied as a pipe presenting hollows wherein the rollers (4) with their profile are biting at least far enough so that the wire remains at a distance from the pipe wall at least in the hollow area on either side of the rollers (4).

Description

Die Erfindung bezieht sich auf einen mit einer Rollenführung für den Draht versehenen Drahthaspel-Verlegearm, bei dem die Rollenführung nach einer Raumkurve gekrümmt und durch mehrere am Verlegearm angeordnete profilierte Rollen gebildet ist, die an der konvexen Seite der Raumkurve jeweils an der Stelle von deren grösster Krümmung angeordnet sind.The invention relates to a wire reel laying arm provided with a roller guide for the wire, in which the roller guide is curved according to a space curve and formed by a plurality of profiled rollers arranged on the laying arm, each on the convex side of the space curve at the location of the largest one Curvature are arranged.

Ein Drahthaspel-Verlegearm dieser Art ist vorbekannt aus der DE-B-2814143. Dieser Verlegearm weist zwei Reihen von Profilrollen auf, die in jeder Reihe aneinander anschliessend so angeordnet sind, dass sie die einzige Führung für den zwischen den beiden Reihen laufenden Draht bildet. Dieses Verlegearm ist konstruktiv und fertigungstechnisch aufwendig und ausserdem mit dem Nachteil behaftet, dass die Rollen infolge unterschiedlicher Belastung dementsprechend unterschiedlich verschleissen.A wire reel laying arm of this type is previously known from DE-B-2814143. This laying arm has two rows of profile rolls which are arranged in each row adjoining one another in such a way that they form the only guide for the wire running between the two rows. This laying arm is structurally and technically complex and also has the disadvantage that the rollers wear differently due to different loads.

Der Erfingung liegt die Aufgabe zugrunde, einen Drahthaspel-Verlegearm der eingangs genannten Art so auszugestalten, dass bei verhältnismässig geringem Aufwand eine exakte und verschleissarme Drahtführung ermöglicht wird. Die Lösung der Aufgabe besteht in den Merkmalen des kennzeichnenden Teils des Anspruchs 1.The invention is based on the task of designing a wire reel laying arm of the type mentioned at the outset in such a way that an exact and low-wear wire guide is made possible with relatively little effort. The solution to the problem consists in the features of the characterizing part of claim 1.

Die Erfindung bringt den Vorteil, dass mit einer geringen Anzahl von Rollen eine ausschliesslich rollende Reibung erzielt wird. Trotzdem ist der neue Verlegearm nicht nur für das Verlegen von dünneren, sondern insbesondere auch von dickeren Drähten geeignet, sogar über die bekannten Walzdrahtdicken hinausgehend. Dabei ist es möglich, den Rollendurchmesser jeweils an verschiedene Belastungen und Verhältnisse anzupassen.The invention has the advantage that an exclusively rolling friction is achieved with a small number of rollers. Nevertheless, the new laying arm is not only suitable for laying thinner, but especially thicker wires, even going beyond the known wire rod thicknesses. It is possible to adapt the roll diameter to different loads and conditions.

Es ist ferner möglich, den Abstand der Rollen zueinander zu variieren. Dabei ist es besonders vorteilhaft, dass dieser Abstand in Bereichen grösserer Krümmung der Raumkurve geringer ist als in den anderen Bereichen, weil dadurch die Führung verbessert wird.It is also possible to vary the distance between the rollers. It is particularly advantageous that this distance is smaller in areas of greater curvature of the space curve than in the other areas, because this improves the guidance.

Dadurch, dass der Verlegearm als Rohr ausgebildet ist, wird ausserdem eine zusätzliche Sicherheit gegen Herausspringen des Drahtes erzielt. Die Ausbildung des Verlegearms nach der Erfindung als Rohr ermöglicht nicht nur eine besonders einfache, zweckmässige und sichere Konstruktion, sondern auch einen Austausch des neuen Verlegearms gegen eines der Verlegerohre, wie sie in bestehenden Anlagen vielfach eingesetzt sind und wegen der starken Reibungen an der Rohrwand schnell verschleissen.The fact that the laying arm is designed as a tube also provides additional security against the wire jumping out. The design of the laying arm according to the invention as a pipe not only enables a particularly simple, functional and safe construction, but also an exchange of the new laying arm for one of the laying pipes, as they are widely used in existing systems and quickly because of the strong friction on the pipe wall wear out.

In der nachfolgend näher erläuterten Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Es zeigen:

  • Fig.1 einen als Rohr ausgebildeten Verlegearm in Ansicht,
  • Fig.2 einen Längsschnitt durch einen Teil des Verlegearms nach Fig.1,
  • Fig. einen Querschnitt durch den als Rohr ausgebildeten Verlegearm im Bereich einer Rolle.
In the drawing explained in more detail below, an embodiment of the invention is shown schematically. Show it:
  • 1 a laying arm designed as a tube in view,
  • 2 shows a longitudinal section through part of the laying arm according to FIG. 1,
  • Fig. A cross section through the laying arm designed as a tube in the region of a roll.

Der rohrförmige Verlegearm 1 einer nicht dargestellten Drahthaspel nimmt an seinem oberen, drehbar an der Drahthaspel gelagerten Ende 2 den von einer Walzenstrasse kommenden gestreckten Draht auf und formt ihn im Verlauf der Raumkurve zu endlosen Ringwindungen, die an seinem unteren Ende 3 austreten.The tubular laying arm 1 of a wire reel (not shown) receives at its upper end 2, which is rotatably mounted on the wire reel, the stretched wire coming from a roller train and forms it in the course of the space curve into endless ring windings which emerge at its lower end 3.

An dem Verlegerohr 1, das einen Innendurchmesser von 40 mm aufweist, sind, wie aus Fig.1 hervorgeht, über seine Länge verteilt acht profilierte Rollen 4 angeordnet, deren Mittenabstand zwischen 250 und 300 mm liegt. Der geringere Abstand gilt dabei für den Bereich des Verlegerohrs, in welchem es die grösste Krümmung aufweist. Im Bereich der Rollen weist das Verlegerohr 1 an der konvexen Seite jeweils eine Ausnehmung 5 auf, in welche die Rollen 4 mit Spiel eingreifen, wie es aus den Fig. 2 und 3 ersichtlich ist. Bei dem verlegten Draht handelt es sich um Stahldraht von 22mm Durchmesser.On the laying pipe 1, which has an inner diameter of 40 mm, as shown in FIG. 1, eight profiled rollers 4 are arranged over its length, the center distance of which is between 250 and 300 mm. The smaller distance applies to the area of the laying pipe in which it has the greatest curvature. In the area of the rollers, the laying pipe 1 has a recess 5 on the convex side, into which the rollers 4 engage with play, as can be seen from FIGS. 2 and 3. The laid wire is steel wire with a diameter of 22mm.

Die Rollen 4 sind auf einer Achse 6 mittels gekapselter Kugellager 7 gelagert und dadurch leicht austauschbar, dass die Achse 6 als Steckachse ausgebildet ist und mit Muttern 8 befestigt wird. Die Befestigung stützt sich dabei beiderseits der jeweils mit einer Bohrung 9 versehenen Schenkel einer U-förmigen Schelle 10 ab, welche das Verlegerohr 1 umschlingt und an diesem durch Schweissnähte 11 befestigt ist.The rollers 4 are mounted on an axle 6 by means of encapsulated ball bearings 7 and are therefore easily exchangeable in that the axle 6 is designed as a plug-in axle and is fastened with nuts 8. The fastening is supported on both sides of the legs of a U-shaped clamp 10 each provided with a bore 9, which wraps around the laying pipe 1 and is fastened to this by welding seams 11.

Eine Schmierung der Kugellager 7 erfolgt zentral über entsprechende Kanäle in der Achse 6 über einen Schmiernippel 12. Eine Kühlung des Drahtes 13 wird in erforderlichem Umfang durch nicht dargestellte Spritzdüsen bewirkt, die das Kühlmedium neben den Rollen 4 in die Ausnehmungen 5 in Bewegungsrichtung des Drahtes 13 eindüsen.The ball bearings 7 are lubricated centrally via corresponding channels in the axis 6 via a lubricating nipple 12. The wire 13 is cooled to the required extent by spray nozzles, not shown, which in addition to the rollers 4, the cooling medium in the recesses 5 in the direction of movement of the wire 13 inject.

Der Draht 13 stützt sich beim Durchlauf durch den Verlegearm 1 lediglich gegen die Rollen 4 ab, wie es aus Fig.2 ersichtlich ist. Das Rohr, das den Verlegearm bildet,-dient dabei lediglich der Halterung der Rollen 4 und gleichzeitig einer sicheren Abschirmung des Drahtes sowie ggf. noch einer Weiterleitung des Kühlmediums. Er kann in bekannter Weise nach einer vorhandenen Schablone entsprechend der vorgesehenen Raumkurve gebogen werden. Die Ausnehmungen 5 werden dann an den für die Rollen 4 vorgesehenen Stellen ausgeschnitten und danach die Schellen 10 für die Rollen 4 zunächst nur angeklemmt. Danach erfolgt das Ausrichten der Schellen 10 in der Weise, dass die Krümmungsnormale 14 senkrecht auf der Drehachse der Rollen 4 steht, wie es in Fig.3 angedeutet ist. Damit ist die Bedingung erfüllt, dass die Rollen 4 da angeordnet sind, wo die Raumkurve an der betreffenden Stelle ihre grösste Krümmung aufweist. Das hat zur Folge, dass die Kugellager 7 nur radial belastet werden und dadurch eine lange Lebensdauer erhalten. Anzahl und Grösse der Rollen 4 richten sich nach der jeweiligen Belastung, wie sie sich aus der Dicke und der Geschwindigkeit des Drahtes jeweils ergeben.The wire 13 is only supported against the rollers 4 during the passage through the laying arm 1, as can be seen from FIG. The tube that forms the laying arm serves only to hold the rollers 4 and at the same time to securely shield the wire and possibly also to pass on the cooling medium. It can be bent in a known manner according to an existing template according to the space curve provided. The recesses 5 are then cut out at the locations provided for the rollers 4 and then the clamps 10 for the rollers 4 are initially only clamped on. The clamps 10 are then aligned in such a way that the normal to curvature 14 is perpendicular to the axis of rotation of the rollers 4, as is indicated in FIG. This fulfills the condition that the rollers 4 are arranged where the space curve has its greatest curvature at the point in question. The result of this is that the ball bearings 7 are only loaded radially and thus have a long service life. The number and size of the rollers 4 depend on the respective load, as they result from the thickness and the speed of the wire.

Nach dem Ausrichten der Schellen 10 werden diese am Verlegearm 1 angeschweisst. In besonderen Fällen kann es vorteilhaft sein, dass die Rollen 4 auch später noch in ihrer Lage verstellbar sein sollen. In dem Fall wird die betreffende Schelle 10 einstellbar am Verlegearm 1 befestigt, was in einfachster Weise durch mindestens eine im Verlegerohr 1 verlagerte Befestigungsschraube, die durch ein in der Schelle 10 angeordnetes Langloch durchgreift, erfolgen kann.After aligning the clamps 10, they are welded to the laying arm 1. In special cases it can be advantageous for the rollers 4 to be adjustable in their position even later should be. In this case, the relevant clamp 10 is fastened to the laying arm 1 in an adjustable manner, which can be done in the simplest way by means of at least one fastening screw displaced in the laying pipe 1, which extends through an elongated hole arranged in the clamp 10.
