Definitions
- the invention relates to a system for processing, such as descaling, embossing and / or drawing, and subsequent straightening of wire with a decoiler, a processing device, in particular a descaling, embossing or drawing device, and a straightening and cutting device in which the wire feed direction In front of and behind the straightening rotor of the straightening device, pairs of drive rollers which detect the wire to be straightened with a clamping connection and a spill downstream of the processing device are arranged in front of the drive rollers.
- This system structure makes it possible to pull the wire through the processing device with much greater tensile force by means of the motor-driven spill, which is wrapped around the wire several times, than would be possible by means of the driving rollers of the straightening device, which work approximately with point contact and with a clamping connection and therefore tend to slip.
- a disadvantage of this type of plant is the high outlay which is caused by the separate drive motors for the spill downstream of the wire processing device and for the drive rollers assigned to the straightening device, and by the control devices for these motors.
- the resulting wire winding is then usually stored temporarily until it is straightened in a straightening device immediately before it is further processed and cut to pieces of the desired length in a cutting device downstream of the straightening device.
- This procedure is labor-intensive and also harbors the risk that a new dirt and oxide layer forms on the newly cleaned wire surface during the intermediate storage, which is detrimental to further processing, in particular a welding process.
- the invention is now concerned with the task of designing a wire processing system of the type specified in the introduction in such a way that the wire can be pulled through the processing device with high tensile force without the previously required high outlay on separate drive motors for the capstan and the drive roller pairs of the straightening device and associated control devices must be accepted.
- This object is achieved in such a way that the capstan and the rollers of the drive roller pairs can be driven by a common motor with different peripheral speeds, the peripheral speed of the rollers of the drive roller pairs being greater than the peripheral speed of the capstan, and that devices for pressing the rollers of the Driving roller pairs with selectable pressure on the wire are provided.
- the high tractive force required behind the processing device is secured by the motor-driven spill, which is wrapped in several wire windings, whereas the drive roller pairs driven by the same motor with somewhat greater circumferential speed and tending to slip only have a smaller one, of which they are easily selected accordingly Must generate clamping force to be applied.
- a wire processing system is known from DE-A1-2 651 812 in which the wire is to be continuously given a torsion or twist size by means of a rotating cold-forming head.
- a disk which is wrapped around it several times and from which the rotary drive for the cold-forming head is derived.
- This disk itself is not driven by a motor, but is only carried along by the wire drawn through the rotating cold-forming head by means of the drive rollers of a subsequent straightening device.
- the disc mentioned does not act as a capstan and therefore does not lead to a relief, but rather to an additional load on the drive rollers of the straightening device, which also exert the necessary tensile force for the wire to be passed through the cold-forming head.
- a wire 1 is drawn off a reel 2 and passed through an emergency shutdown device 3 known per se. This serves to shut down the entire facility add if, for example, the wire drawn off the reel forms a loop which should lead to a wire break when passing through the subsequent device.
- an emergency shutdown device 3 known per se. This serves to shut down the entire facility add if, for example, the wire drawn off the reel forms a loop which should lead to a wire break when passing through the subsequent device.
- a descaling device with a crushing descaling section 4 and a brush descaling section 5 and finally a straightening device 6 with scissors 7. All of the devices mentioned in the system are known per se in various designs.
- a motor 10 is provided in the straightening and cutting device 6, which on the one hand drives a capstan 13 via an intermediate gear 11 and a worm gear 12, around which the wire 1 is guided in one or more turns, and on the other hand Via a V-belt drive 14 drives pairs of drive rollers 15, 16 which move the wire through the straightening device 6.
- the transmission ratios of the gears 12 and 14 are coordinated with one another in such a way that the peripheral speed of the capstan 13 is slightly less than the peripheral speed of the drive roller pairs 15, 16.
- the drive rollers of the drive roller pairs 15, 16 can be adjusted by suitable devices, for example pressure springs 17 and screw spindles 18, with respect to the contact pressure they exert on the wire.
- suitable devices for example pressure springs 17 and screw spindles 18, with respect to the contact pressure they exert on the wire.
- the contact pressure of the drive rollers on the wire 1 is dimensioned such that the tensile force exerted by the drive rollers on the wire 1 becomes sufficiently large so that the frictional force acting between the wire 1 and the capstan 13, on the one hand, ensures that the wire 1 is pushed forward without slippage ensured by the descaling device, but on the other hand, a slip is possible between the drive rollers and the wire 1 in order to take into account the different peripheral speeds of the capstan and the drive rollers.
- the traction rollers which turn a little faster than the wire feed speed, exert a uniform tensile force on the wire. As a result, the frictional force between the wire and the circumference of the spill remains constant, which ensures a constant feed speed of the wire.

- scissors 22 and an outlet path 23 are provided after the straightening device, into which the straightened wire is conveyed.
- the scissors which are also driven by the motor 10 via transmission elements, which are not shown because they are not essential to the invention and are known, are activated and separate a piece of the desired type Length from the descaled and straightened wire.

Description
Die Erfindung betrifft eine Anlage zum Bearbeiten, wie Entzundern, Prägen und/oder Ziehen, und nachfolgendem Richten von Draht mit einer Ablaufhaspel, einer Bearbeitungsvorrichtung, insbesondere einer Entzunderungs-, Präge- oder Ziehvorrichtung, und einer Richt- und Schneidvorrichtung, bei welcher die Drahtvorschubrichtung vor und hinter dem Richtrotor der Richtvorrichtung Paare von den zu richtenden Draht mit Klemmschluß erfassenden Treibrollen und vor den Treibrollen ein der Bearbeitungsvorrichtung nachgeschaltetes Spill angeordnet sind.The invention relates to a system for processing, such as descaling, embossing and / or drawing, and subsequent straightening of wire with a decoiler, a processing device, in particular a descaling, embossing or drawing device, and a straightening and cutting device in which the wire feed direction In front of and behind the straightening rotor of the straightening device, pairs of drive rollers which detect the wire to be straightened with a clamping connection and a spill downstream of the processing device are arranged in front of the drive rollers.
Bei einer aus der DE-AL -2 635 437 bekannten, zum Drahtziehen bestimmten Anlage dieser Gattung ist dem Zieheisen ein Spill nachgeschaltet, das vom gezogenen Draht mehrfach umschlungen und von einem drehzahlgeregelten Motor angetrieben wird. Der Draht wird vom Spill mittels Treibrollen abgezogen und durch eine Richtvorrichtung hindurchgeführt.In a system of this type known from DE-AL -2 635 437, intended for wire drawing, a spill is connected downstream of the drawing iron, which is wound several times by the drawn wire and driven by a speed-controlled motor. The wire is drawn off the capstan by means of drive rollers and passed through a straightening device.
Dieser Anlagenaufbau ermöglicht es, mittels des vom Draht mehrfach umschlungenen, motorisch angetriebenen Spills den Draht durch die Bearbeitungsvorrichtung mit wesentlich größerer Zugkraft hindurchzuziehen, als dies mittels der angenähert mit Punktberührung und mit Klemmschluß arbeitenden und daher zum Schlupf neigenden Treibrollen der Richtvorrichtung möglich wäre. Nachteilig ist bei dieser Anlagenbauweise allerdings der hohe Aufwand, der durch die getrennten Antriebsmotore für das der Drahtbearbeitungsvorrichtung nachgeschaltete Spill und für die der Richtvorrichtung zugeordneten Treibrollen sowie durch die Regelvorrichtungen für diese Motoren verursacht wird. Man verzichtet deshalb häufig, beispielsweise beim Brechentzundern von warm gewalztem Draht durch Hindurchführen desselben durch zwei im rechten Winkel zueinander stehende Rollensätze, welche den Draht starken Formänderungen unterwerfen, auf ein unmittelbar an die Bearbeitung anschließendes Richten des Drahtes, indem man die zum Hindurchführen des Drahtes durch die Bearbeitungsvorrichtung erforderliche hohe Zugkraft mittels einer motorisch angetriebenen Trommel erzeugt, an welcher der Draht verankert und auf welche er unmittelbar nach der Bearbeitung aufgewickelt wird.This system structure makes it possible to pull the wire through the processing device with much greater tensile force by means of the motor-driven spill, which is wrapped around the wire several times, than would be possible by means of the driving rollers of the straightening device, which work approximately with point contact and with a clamping connection and therefore tend to slip. A disadvantage of this type of plant, however, is the high outlay which is caused by the separate drive motors for the spill downstream of the wire processing device and for the drive rollers assigned to the straightening device, and by the control devices for these motors. It is therefore often avoided, for example in the descaling of hot-rolled wire by passing it through two sets of rollers which are at right angles to one another and which subject the wire to major changes in shape, to straightening the wire immediately after processing, by passing through the wire through it the machining device generates the required high tensile force by means of a motor-driven drum to which the wire is anchored and onto which it is wound up immediately after machining.
Der entstandene Drahtwickel wird üblicherweise anschließend zwischengelagert, bis er unmittelbar vor seiner Weiterverarbeitung in einer Richtvorrichtung geradegerichtet und in einer der Richtvorrichtung nachgeschalteten Schneidvorrichtung auf Stücke gewünschter Länge zugeschnitten wird. Diese Vorgangsweise ist arbeitsintensiv und birgt überdies die Gefahr, daß sich während der Zwischenlagerung auf der eben gereinigten Drahtoberfläche eine neue Schmutz- und Oxydschicht bildet, die der weiteren Verarbeitung, insbesondere einem Schweißvorgang, abträglich ist.The resulting wire winding is then usually stored temporarily until it is straightened in a straightening device immediately before it is further processed and cut to pieces of the desired length in a cutting device downstream of the straightening device. This procedure is labor-intensive and also harbors the risk that a new dirt and oxide layer forms on the newly cleaned wire surface during the intermediate storage, which is detrimental to further processing, in particular a welding process.
Die Erfindung befaßt sich nun mit der Aufgabe, eine Drahtbearbeitungsanlage der einleitend angegebenen Gattung so auszubilden, daß der Draht mit hoher Zugkraft durch die Bearbeitungsvorrichtung hindurchgezogen werden kann, ohne daß der bisher erforderliche hohe Aufwand an getrennten Antriebsmotoren für das Spill und die Treibrollenpaare der Richtvorrichtung und an zugehörigen Regelvorrichtungen hingenommen werden muß.The invention is now concerned with the task of designing a wire processing system of the type specified in the introduction in such a way that the wire can be pulled through the processing device with high tensile force without the previously required high outlay on separate drive motors for the capstan and the drive roller pairs of the straightening device and associated control devices must be accepted.
Diese Aufgabe wird erfindungsgemäß in der Weise gelöst, daß das Spill und die Rollen der Treibrollenpaare von einem gemeinsamen Motor mit unterschiedlicher Umfangsgeschwindigkeit antreibbar sind, wobei die Umfangsgeschwindigkeit der Rollen der Treibrollenpaare größer als die Umfangsgeschwindigkeit des Spills ist, und daß Vorrichtungen zum Anpressen der Rollen der Treibrollenpaare mit wählbarem Druck an den Draht vorgesehen sind.This object is achieved in such a way that the capstan and the rollers of the drive roller pairs can be driven by a common motor with different peripheral speeds, the peripheral speed of the rollers of the drive roller pairs being greater than the peripheral speed of the capstan, and that devices for pressing the rollers of the Driving roller pairs with selectable pressure on the wire are provided.
Bei dieser Anlage wird die hinter der Bearbeitungsvorrichtung erforderliche hohe Zugkraft durch das von mehreren Drahtwindungen umschlungene, motorisch angetriebene Spill gesichert, wogegen die vom gleichen Motor mit etwas größerer Umfangsgeschwindigkeit angetriebenen und zum Schlupf neigenden Treibroilenpaare nur noch eine kleinere, von ihnen ohne weiteres durch entsprechend gewählten Klemmdruck aufzubringende Zugkraft erzeugen müssen.In this system, the high tractive force required behind the processing device is secured by the motor-driven spill, which is wrapped in several wire windings, whereas the drive roller pairs driven by the same motor with somewhat greater circumferential speed and tending to slip only have a smaller one, of which they are easily selected accordingly Must generate clamping force to be applied.
Es sei erwähnt, daß aus der DE-A1-2 651 812 eine Drahtbearbeitungsanlage bekannt ist, in welcher dem Draht mittels eines rotierenden Kaltformkopfes kontinuierlich eine Torsions oder Verdrallgröße erteilt werden soll. Hierbei ist vor dem rotierenden Kaltformkopf zum Spannen des Drahtes eine von diesem mehrfach umschlungene Scheibe angeordnet, von welcher der Drehantrieb für den Kaltformkopf abgeleitet wird. Diese Scheibe wird selbst nicht motorisch angetrieben, sondern nur von dem mittels der Treibrollen einer nachfolgenden Richtvorrichtung durch den rotierenden Kaltformkopf hindurchgezogenen Draht mitgenommen. Die erwähnte Scheibe wirkt hierbei nicht als Spill und führt daher nicht zu einer Entlastung, sondern zu einer zusätzlichen Belastung der Treibrollen der Richtvorrichtung, die auch die erforderliche Zugkraft für das Hindurchführen des Drahtes durch den Kaltformkopf aufbringen.It should be mentioned that a wire processing system is known from DE-A1-2 651 812 in which the wire is to be continuously given a torsion or twist size by means of a rotating cold-forming head. Here, in front of the rotating cold-forming head for tensioning the wire, there is a disk which is wrapped around it several times and from which the rotary drive for the cold-forming head is derived. This disk itself is not driven by a motor, but is only carried along by the wire drawn through the rotating cold-forming head by means of the drive rollers of a subsequent straightening device. The disc mentioned does not act as a capstan and therefore does not lead to a relief, but rather to an additional load on the drive rollers of the straightening device, which also exert the necessary tensile force for the wire to be passed through the cold-forming head.
Die Erfindung wird nun unter Bezugnahme auf die Zeichnungen an einem Ausführungsbeispiel näher erläutert. Es zeigt
- Fig. 1 eine schematische Ansicht einer zum Entzundern und Richten von Drähten dienenden Anlage gemäß der Erfindung,
- Fig. 2 die Vorschub- und Richtvorrichtung dieser Anlage in Ansicht und
- Fig. 3 eine Draufsicht zu Fig. 2.
- 1 is a schematic view of a system for descaling and straightening wires according to the invention,
- Fig. 2, the feed and straightening device of this system in view and
- 3 is a top view of FIG. 2.
Gemäß dem Schema von Fig. 1 wird ein Draht 1 von einer Haspel 2 abgezogen und durch eine an sich bekannte Notabschaltvorrichtung 3 geführt. Diese dient dazu, die gesamte Anlage stillzusetzen, wenn beispielsweise der von der Haspel abgezogene Draht eine Schleife bildet, die beim Durchlaufen der nachfolgenden Vorrichtung zu einem Drahtbruch führen müßte. Anschließend folgen eine Entzunderungsvorrichtung mit einem Brechentzunderungsabschnitt 4 und einem Bürstenentzunderungsabschnitt5 und schließlich eine Richtvorrichtung 6 mit einer Schere 7. Alle genannten Vorrichtungen der Anlage sind an sich in verschiedenen Ausführungen bekannt.According to the diagram in FIG. 1, a wire 1 is drawn off a
Gemäß den Fig. 2 und 3 ist in der Richt- und Schneidvorrichtung 6 ein Motor 10 vorgesehen, der über ein Zwischengetriebe 11 und ein Schneckengetriebe 12 einerseits ein Spill 13 antreibt, um welches der Draht 1 in einer oder mehreren Windungen herumgeführt ist, und andererseits über ein Keilriemengetriebe 14 Treibrollenpaare 15, 16 antreibt, welche den Draht durch die Richtvorrichtung 6 bewegen. Die Übersetzungsverhältnisse der Getriebe 12 und 14 sind so aufeinander abgestimmt, daß die Umfangsgeschwindigkeit des Spills 13 geringfügig kleiner ist als die Umfangsgeschwindigkeit der Treibrollenpaare 15, 16.According to FIGS. 2 and 3, a
Die Treibrollen der Treibrollenpaare 15, 16 sind durch geeignete Einrichtungen, beispielsweise Anpreßfedern 17 und Schraubenspindeln 18, bezüglich des von ihnen auf den Draht ausgeübten Anpreßdruckes einstellbar. Mit Hilfe dieser Einrichtungen wird der Anpreßdruck der Treibrollen auf den Draht 1 so bemessen, daß die von den Treibrollen auf den Draht 1 ausgeübte Zugkraft hinlänglich groß wird, damit die zwischen dem Draht 1 und dem Spill 13 wirkende Reibungskraft einerseits ein schlupffreies Vorschieben des Drahtes 1 durch die Entzunderungsvorrichtung sicherstellt, anderseits aber zwischen den Treibrollen und dem Draht 1 ein Schlupf möglich ist, um die unterschiedlichen Umfangsgeschwindigkeiten des Spills und der Treibrollen zu berücksichtigen.The drive rollers of the
Durch die Treibrollen, die sich etwas schneller drehen als es der Vorschubgeschwindigkeit des Drahtes entspricht, wird auf den Draht eine gleichmäßige Zugkraft ausgeübt. Dadurch bleibt die Reibungskraft zwischen dem Draht und dem Umfang des Spills konstant, wodurch eine konstante Vorschubgeschwindigkeit des Drahtes sichergestellt wird.The traction rollers, which turn a little faster than the wire feed speed, exert a uniform tensile force on the wire. As a result, the frictional force between the wire and the circumference of the spill remains constant, which ensures a constant feed speed of the wire.
Der Richtrotor 20 wird ebenfalls vom Motor 10 über einen Keilriementrieb 21 angetrieben. Auslaufseitig sind im Anschluß an die Richtvorrichtung eine Schere 22 und eine Auslaufbahn 23 vorgesehen, in welche der gerichtete Draht gefördert wird. Sobald der Draht einen nicht dargestellten, längs der Auslaufbahn 23 verstell- und feststellbar angeordneten Endanschlag berührt, wird die Schere, die über nicht dargestellte, weil nicht erfindungswesentliche und allgemein bekannte Übertragungsorgane gleichfalls vom Motor 10 angetrieben wird, in Tätigkeit gesetzt und trennt ein Stück gewünschter Länge vom entzunderten und gerichteten Draht ab.The straightening
