Abstract
Description
Die Erfindung betrifft eine Richtmaschine zum Ausrichten von Draht gemäß Oberbegriff des Patentanspruchs 1 mit einem Richtsatz, der mehrere in ihrer radialen Lage relativ zur Längsachse des Richtsatzes einstellbare Richteinheiten umfaßt. (sieche z.B. EP-A-0 287 494).The invention relates to a straightening machine for aligning wire according to the preamble of claim 1 with a standard sentence, the several adjustable in their radial position relative to the longitudinal axis of the straightening set Straightening units included. (see e.g. EP-A-0 287 494).
Eine Richtmaschine mit einstellbaren Richteinheiten ist aus der EP-A1-620-058 bekannt. Bei dieser Richtmaschine wird der Richtsatz von einem Rotor gebildet, der von einem Drehantrieb um seine Längsachse drehbar ist und der als Richteinheiten Richtdüsen umfaßt, durch die der auszurichtende Draht geführt wird. Die Richtdüsen sind radial verschiebbar gelagert und sie können in ihrer Lage gemeinsam über ein Verschubelement eingestellt werden, das schiefe Ebenen aufweist, die seitlich an den Haltern der Richtdüsen angreifen.A straightening machine with adjustable straightening units is known from EP-A1-620-058 known. In this straightening machine, the straightening set is formed by a rotor, which consists of a rotary drive is rotatable about its longitudinal axis and the straightening nozzles as straightening units includes, through which the wire to be aligned is passed. The directional nozzles are radially displaceably mounted and they can in their position together via a sliding element can be set, which has inclined planes, the sides of the Attack holders of the straightening nozzles.
Nachteilig ist bei dieser Einrichtung, daß der Rotor ein relativ hohes Gewicht und somit ein hohes Trägheitsmoment beim Beschleunigen bzw. Bremsen aufweist, daß die Verstellung relativ grob ist und daß eine Anpassung an die Eigenschaften des Drahtes (z.B. dessen innere Spannungen je nach Herstellungsart) nur begrenzt möglich ist.The disadvantage of this device is that the rotor has a relatively high weight and thus has a high moment of inertia when accelerating or braking that the Adjustment is relatively rough and that an adjustment to the properties of the wire (e.g. its internal stresses depending on the type of manufacture) is only possible to a limited extent.
Bei anderen herkömmlichen Richtmaschinen werden die Richtdüsen einzeln manuell verstellt, was natürlich einen hohen Arbeitsaufwand mit sich bringt. Man sieht daher üblicherweise mehrere auf verschiedene Drahtdurchmesser eingestellte Rotoren vor, die bei Bedarf ausgetauscht werden.In other conventional straightening machines, the straightening nozzles are individually manual adjusted, which of course involves a lot of work. So you can see usually several rotors set to different wire diameters, which are exchanged if necessary.
Aus der EP-A1-619 154 ist eine Richtmaschine bekannt, bei der Richtsatz von mehreren Richtrollen gebildet wird, von denen jede zweite Richtrolle über einen Stellknopf in ihrer radialen Lage einstellbar ist. Auch bei dieser Richtmaschine ist die Umstellung auf einen anderen Drahtdurchmesser arbeitsaufwendig.A straightening machine is known from EP-A1-619 154, with the straightening set of several Straightening rollers is formed, of which every second straightening roller in a its radial position is adjustable. The change is also in this straightener to another wire diameter labor-intensive.
Aufgabe der Erfindung ist es, eine neuartige Richtmaschine bereitzustellen, durch welche die Nachteile der bisher bekannten Richtmaschinen überwunden werden und welche schnell und genau reproduzierbar auf verschiedene Drahtdurchmesser eingestellt werden kann. The object of the invention is to provide a novel straightening machine, by means of which the disadvantages of the previously known straightening machines are overcome and which can be quickly and precisely reproducibly adjusted to different wire diameters can be.
Erfindungsgemäß gelingt dies bei einer Richtmaschine der eingangs genannten Art durch die Merkmale des Patentanspruchs 1.This is achieved according to the invention in a straightening machine of the type mentioned at the beginning by the features of claim 1.
Aufgrund der fernbedienten bzw. ferngesteuerten Einstellung der Richteinheiten muß sich der Operator nicht in den Gefahrenbereich der Maschine begeben.Due to the remote-controlled or remote-controlled setting of the straightening units the operator does not enter the danger area of the machine.
Die Erfindung kann bei Richtmaschinen mit einem Rollenrichtsatz eingesetzt werden, bei dem die Richteinheiten durch Rollen gebildet werden, zwischen denen der Draht geführt ist. In einem bevorzugten Ausführungsbeispiel der Erfindung sind als Richteinheiten Richtdüsen vorgesehen, durch welche der Draht geführt ist. Dadurch, daß die Stelleinheiten beim Betrieb der Richtmaschinen von den Richteinheiten entkoppelt werden, kann die rotierende Masse gering gehalten werden.The invention can be used in straightening machines with a roller straightening set, in which the straightening units are formed by rollers, between which the wire is led. In a preferred embodiment of the invention are as straightening units Directional nozzles are provided through which the wire is guided. As a result of that the actuating units are decoupled from the straightening units when operating the straightening machines the rotating mass can be kept low.
Weitere Vorteile und Einzelheiten der Erfindung werden im folgenden anhand der beiliegenden
Zeichnungen erläutert. In dieser zeigt:
Die in den Fig. 1 bis 3 gezeigte Richtmaschine weist einen um die Achse 1 drehbar
gelagerten Rotor 2 auf, der die Richteinheiten 3 enthält. Der Rotor 2 wird über Keilriemen
4 und zugehörige Keilwellen 5 von einem Motor 6 angetrieben. Der auszurichtende
Draht wird von einem Coil abgezogen und längs durch den Rotor der Richtmaschine
geführt. In der Folge kann der ausgerichtete Draht zu einem geraden Rundstahlstab
abgelängt werden.The straightening machine shown in FIGS. 1 to 3 has a rotatable around the axis 1
mounted rotor 2, which contains the straightening units 3. The rotor 2 is via V-
Der Richtsatz 7 umfaßt im gezeigten Ausführungsbeispiel fünf als Richtdüsen 8 ausgebildete
Richteinheiten 3, die bezüglich ihrer axialen Lage im Rotor 2 fixiert sind und
radial , d.h. senkrecht zur Längsachse 1 des Richtsatzes 7 von einer Stellvorrichtung
10 einzeln einstellbar sind.In the exemplary embodiment shown, the straightening set 7 comprises five straightening nozzles 8
Straightening units 3, which are fixed in terms of their axial position in the rotor 2 and
radial, i.e. perpendicular to the longitudinal axis 1 of the straightening set 7 from an adjusting
Die Richtdüse 8 weist eine Düsenplatte 9 auf, die die eigentliche Düse 11 enthält. Die
Düsenplatte 9 ist im Düsenrahmen 12 über Führungsleisten 12a, die in Führungsnuten
der Düsenplatte 9 eingreifen, verschiebbar gelagert. Die radiale Einstellung der
Richtdüse 8 erfolgt über einen Spindeltrieb 13. Dieser wird von einem in der Düsenplatte
9 enthaltenen Hohlgewinde 9a und einer im Düsenrahmen 12 gelagerten Einstellschraube
14 gebildet.The directional nozzle 8 has a
Um die Einstellschraube gegen ungewolltes Verdrehen im Betrieb der Richtmaschine
zu sichern, ist eine Rastvorrichtung 15 (siehe Fig. 2) vorgesehen, welche einen mit der
Einstellschraube 14 starr verbundenen und mit radialen Bohrungen versehenen
Rastring 16 sowie in einem Bolzen 17 gelagerte unter Federkraft stehende Rastkugeln
umfaßt, die in die Bohrungen des Rastringes einrasten können. Neben der
Verdrehsicherung wird durch die Rastvorrichtung eine definierte Winkelstellung der
Einstellschraube 14 erreicht. Weiters ist eine mit der Einstellschraube 14 verstiftete
Dichthülse 18 vorgesehen, um das Eindringen von Schmutz zu verhindern.Around the adjusting screw against unintentional turning during operation of the straightening machine
To secure, a locking device 15 (see Fig. 2) is provided, which one with the
Die Stellvorrichtung 10 umfaßt mehrere den Richteinheiten 3 zugeordnete Stelleinheiten
20, wobei für jede Richteinheit 3 jeweils eine Stelleinheit 20 vorgesehen ist. Die
Stelleinheiten 20 werden gemeinsam über eine Kette 21 angetrieben, welche über ein
Kettenrad 22 von einem Stellantriebsmotor 23 angetrieben wird.The
Die Stelleinheiten 20 weisen Stellwellen 24 auf, deren Stellnüsse 25 mit den Einstellschrauben
14 in Eingriff gebracht werden können. Zur Übertragung der Drehbewegung
auf die Stellwellen 24 sind Klemmkupplungen vorgesehen, die von der Kette 21 über
Kettenräder 26 angetriebene Keilmuffen 27 umfassen, in denen die Stellwellen 24, die
als Keilwellen ausgebildet sind, gelagert sind. Die Stellwellen 24 sind in den Keilmuffen
27 daher drehfest aber von pneumatischen Kolben-Zylindereinheiten 28 axial
verschiebbar gelagert und können von den Kolben-Zylindereinheiten 28 von einer
ersten passiven Position in eine zweite aktive Position, in der sie mit der jeweiligen
Einstellschraube in Eingriff sind, überführt werden.The actuating
Die Einstellung der Stelleinheiten erfolgt nun dadurch, daß zunächst der Rotor in die
Einstellposition, in der sich die Verschiebeachse 29 der jeweiligen Richtdüse 8 mit der
Achse 30 der Stelleinheit 20 deckt, gebracht wird. In der Folge wird eine der Stellwellen
24 mittels der Kolben-Zylindereinheit 28 in die aktive Position abgesenkt bis die
Stellnuß 25 auf der Einstellschraube 14 sitzt. Über den Stellantriebsmotor 23 wird nun
die Einstellschraube um den gewünschten Winkelbereich verdreht. Dabei kann zur
Überwachung und Aufnahme der Drehbewegung der Einstellschraube 14 ein Drehgeber
31 vorgesehen sein. Es kann auch als Stellantriebsmotor 23 ein Schrittmotor
vorgesehen sein, der um einen definierten Winkelbetrag gedreht werden kann, sodaß
in diesem Fall kein Drehgeber nötig ist. Auf diese Weise kann eine definierte Stellung
der Düse 11 angefahren werden und in einem elektronischen Speicher einer Steuereinrichtung
abgespeichert werden. Anschließend wird die Stellwelle 24 zurückgefahren.
Der Vorgang kann in der Folge für alle Richtdüsen 8 wiederholt werden.The setting of the actuators is now done by first turning the rotor into the
Setting position in which the
Die Steuerung des Einstellvorganges kann von einem Benutzer über ein Bedienpult vorgenommen werden. Es ist aber auch möglich, eine Steuereinrichtung vorzusehen, die den gesamten Einstellvorgang anhand von zuvor abgespeicherten Einstellwerten automatisch und selbstätig ausführt.A user can control the setting process via a control panel be made. But it is also possible to provide a control device which the entire setting process based on previously stored setting values executes automatically and automatically.
Da beispielsweise in warmgewalzten und kaltgezogenen Drähten sehr unterschiedliche innere Spannungen auftreten, können einmal gefundene optimale Einstellungen für einen bestimmten Drahttyp und Drahtdurchmesser auf diese Weise einfach reproduziert werden.Because, for example, very different in hot-rolled and cold-drawn wires internal tensions can occur once optimal settings for reproduces a certain wire type and wire diameter easily in this way become.
Ein bedeutender Vorteil der erfindungsgemäßen Richtmaschine besteht darin, daß die rotierenden Massen des verstellbaren Rotors nur geringfügig höher sind als bei herkömmlichen nicht ferngesteuert versellbaren Rotoren. An important advantage of the straightening machine according to the invention is that the rotating masses of the adjustable rotor are only slightly higher than conventional ones rotors that cannot be remotely controlled.
Der Rotor kann als Richteinheiten anstelle von Richtdüsen auch Richtrollen aufweisen, über die der Draht geführt ist. Die Oberfläche einer solchen Richtrolle weist dabei im allgemeinen eine konkave, in etwa parabolische Profilierung auf. Die Richtrollen sind wiederum über Spindeltriebe in ihren radialen Lagen einstellbar und zum individuellen Einstellen der radialen Lagen der Richtrollen ist eine Stellvorrichtung vorgesehen, die der zuvor beschriebenen entspricht.The rotor can also have straightening rollers as straightening units instead of straightening nozzles, over which the wire is passed. The surface of such a straightening roll shows in generally a concave, roughly parabolic profile. The judging roles are again in their radial positions adjustable via spindle drives and individual Adjustment of the radial positions of the straightening rollers is provided by an adjusting device corresponds to that previously described.
Der erfindungsgemäße Gedanke, eine Stellvorrichtung zum fernbedienbaren bzw. gesteuerten
Einstellen der radialen Lager der Richteinheiten vorzusehen, ist nicht auf
Richtmaschinen mit einem Rotorrichtsatz beschränkt, sondern auch bei Richtmaschinen
mit einem feststehenden Rollenrichtsatz anwendbar, wie in Fig. 4 gezeigt. Die
Stelleinheiten 20 der Stellvorrichtung 10 sind hier nur den oberen sechs Rollen 40 individuell
zugeordnet. Genausogut könnten auch die unteren fünf Rollen 40 einzeln verstellbar
ausgebildet sein. Die Stellvorrichtung 10 funktioniert wiederum auf genau die
gleiche Weise wie zuvor beschrieben und zur radialen Verstellung der Rollen 40 kann
wiederum ein Spindeltrieb vorgesehen sein. Bevorzugterweise werden in diesem Fall
zwei der in Fig. 4 gezeigten Richtsätze verwendet, welche senkrecht aufeinander
stehen und die der Draht nacheinander durchläuft.The idea according to the invention, an actuating device for remote-controlled or controlled
Adjustment of the radial bearings of the straightening units is not necessary

applicable with a fixed roller straightening set, as shown in Fig. 4. The
