Description
Die Erfindung betrifft einen Richtapparat für drahtförmiges, mehrdrahtförmiges oder rohrförmiges Richtgut mit mehreren in zwei parallelen Ebenen angeordneten drehbaren Richtrollen, deren Drehachsen in zwei relativ gegeneinander beweglich angeordneten einen Grundkörper bildenden Körperteilen gelagert sind, wobei die Körperteile auf Führungen angeordnet sind und ein Schließwerk aufweisen.The invention relates to a straightening apparatus for wire-shaped, multi-wire or tubular straightening material with a plurality of rotatable straightening rollers arranged in two parallel planes, the axes of rotation of which are mounted in two body parts forming a basic body and being movable relative to one another, the body parts being arranged on guides and having a locking mechanism.
Derartige Richtapparate sind z. B. aus dem Prospekt ER 5 vom Januar 1984 der Firma Witels Apparate-Maschinen Albert GmbH & Co KG, Berlin, bekannt.Such straighteners are such. B. from the
Mit höheren Anforderungen an die Qualität des Richtens, aber auch an die Schnelligkeit des Einrichtens derartiger Richtapparate ergeben sich bei den bekannten Richtapparaten Probleme. So weisen die bekannten Schließwerke einen Exzenter auf, der mit einem Hebel verbunden ist und je nach der von Hand aufgewendeten Kraft die beiden relativ zueinander beweglichen Körperteile aufgrund von Reibungskräften in einer Schließstellung hält. Zum Öffnen wird der Hebel in eine Offenstellung verstellt und die beiden Körperteile müssen in ihre Offenstellung von Hand bzw. mittels eines Werkzeugs gebracht werden, was einerseits aufwendig ist, andererseits auch die Gefahr von Beschädigungen mit sich bringt. Mit zunehmender Abnutzung des Exzenters, der durch Reibung - in der Regel auf Metall - in seine Schließstellung gebracht wird, und durch im Laufe des Betriebs auftretende zunehmende Verunreinigungen verändert sich die Null-Lage des Richtapparates, was zu Störungen beim Richten des Richtguts, d. h. zu Ausschuß führt. Es ist somit eine Reinigung und/oder ein Austausch von Teilen und eine Neujustierung in dem Falle, daß die Richtrollen fest angeordnet sind oder in dem Falle, daß mindestens ein Teil der Richtrollen verstellbar angeordnet ist, ein aufwendiges Nachstellen der einzelnen Richtrollen erforderlich.With higher demands on the quality of straightening, but also on the speed of setting up such straightening devices, problems arise with the known straightening devices. For example, the known locking mechanisms have an eccentric which is connected to a lever and, depending on the force applied by hand, holds the two body parts which are movable relative to one another in a closed position due to frictional forces. To open it, the lever is moved into an open position and the two body parts have to be brought into their open position by hand or by means of a tool, which on the one hand is complex and on the other hand also entails the risk of damage. With increasing wear of the eccentric, which is brought into its closed position by friction - as a rule on metal - and due to increasing contamination during operation, the zero position of the straightening apparatus changes, which leads to malfunctions when straightening the straightening goods, ie leads to committee. It is therefore a cleaning and / or replacement of parts and readjustment in the event that the straightening rollers are fixedly arranged or in the case that at least some of the straightening rollers are arranged to be adjustable, a complex readjustment of the individual straightening rollers is necessary.
Aufgabe der Erfindung ist es, einen Richtapparat mit den Merkmalen des Oberbegriffs des Anspruchs 1 dahingehend zu verbessern, daß auch über längere Zeiträume eine einmal definierte Null-Stellung aufrechterhaltbar ist, ohne daß ein Nachstellen oder ein Austausch von Teilen erforderlich ist.The object of the invention is to improve a straightening apparatus with the features of the preamble of

Der in Fig. 1 dargestellte Richtapparat weist einen Grundkörper 1 auf, der aus zwei Körperteilen 2 und 3 besteht. Die beiden Körperteile 2 und 3 sind auf zwei parallel zueinander angeordneten Führungsbolzen 4 angeordnet, die als Führungen dienen. Mit einem Ende sind die Führungsbolzen 4 mit einem Körperteil 2 oder 3 fest verbunden, während der andere Körperteil 2 oder 3 auf dem Führungsbolzen 4 gleitbar angeordnet ist. Die Führungsbolzen 4 sind jeweils in einer den Grundkörper 1 durchdringenden durchgehenden Bohrung 5 angeordnet bzw. befestigt, wobei die Bohrung 5 in den Körperteilen 2 und 3 jeweils eine Erweiterung 6, 6' aufweist, in der auf den jeweiligen Führungsbolzen 4 aufgesetzt eine Schraubenfeder 7 angeordnet ist, die sich gegen die Enden der Erweiterung 6, 6' abstützt. Die Schraubenfeder 7 wird im Ausführungsbeispiel durch eine Schutzhülse 8 überdeckt. Die Schutzhülse 8 ist so dimensioniert, daß sie einerseits das Aneinanderliegen der Körperteile 2 und 3 nicht behindert und andererseits in der Offenstellung des Richtapparats die Schraubenfeder 7 und entsprechend auch den Führungsbolzen 4 vollständig abdeckt, so daß sowohl die Feder 7 als auch der Führungsbolzen 4 und ihre Bewegungsbahnen vor Verunreinigungen geschützt sind.The straightening apparatus shown in Fig. 1 has a
Der Körperteil 2 weist eine ungerade Anzahl an Richtrollen 9 und der andere Körperteil 3 eine gerade Anzahl von Richtrollen 9 auf, die auf Lücke und in gleichen Abständen voneinander angeordnet sind. An beiden Seitenflächen des Körperteils 3 ist jeweils ein Exzenter 10 in Form einer Scheibe drehbar gelagert. Der Exzenter 10 ist über eine an ihm mittels eines Befestigungsstifts 12 angelenkte Zugstange 11 am Körperteil 2 mittels eines Befestigungsstifts 12' angelenkt. Die Exzenter 10 beider Seiten sind im Ausführungsbeispiel mit einem gemeinsamen Bedienungshebel 13 verbunden, der als durchsichtige Schutzhaube gestaltet ist, die in der Schließstellung des Richtapparates die Richtrollen 9 von oben vollständig überdeckt.The
Im Ausführungsbeispiel sind auf den Körperteilen 2 und 3 Deckplatten 14, 14' angeordnet, die eine Höhe aufweisen, die die der jeweils verwendeten Richtrollen 9 in ihrer Arbeitsstellung etwas überragt, und auf deren einer sich der Bedienungshebel 13 - die Schutzhaube - in der Schließstellung des Richtapparates abstützt.In the exemplary embodiment,
Im auf den Führungsbolzen 4 beweglichen Körperteil 2 weisen die Führungsbolzen 4 auf ihrer zum Boden des Richtapparates gerichteten unteren Seite jeweils eine Quernut 15 auf, die zur Aufnahme je eines der freien Enden 16, 16' einer zentral mittels einer Schraube 17 in einer Ausnehmung des Bodens befestigten Blattfeder 18 dient. Die Blattfeder 18 ist derart vorgespannt, daß sie gegen die Quernut 15 drückt und in dieser einrastet, d. h. eine definierte Rastverbindung bildet.In the
Im Körperteil 2 und in der Deckplatte 14 sind zwischen der Schraube 17 in der Nähe der Führungsbolzen 4 Bohrungen 19 vorgesehen, in denen jeweils ein Entriegelungsstift 20 mit einer über die Deckplatte 14 hinausgeführten Druckkappe 21 angeordnet ist, wobei sich die freien Enden der Entriegelungsstifte 20 gegen die Blattfeder 18 abstützen.In the
Der Richtapparat arbeitet wie folgt.The straightener works as follows.
Zunächst ist der Richtapparat durch die Schraubenfedern 7 in einer definierten Offenstellung, wobei der Bedienungshebel 13 (die Schutzhaube) nahezu senkrecht steht und den ungehinderten Zugang zu den Richtrollen 9 und zum Einführen eines Richtguts ermöglicht. Hierbei befindet sich die Blattfeder 18 außerhalb der Quernuten 15 der Führungsbolzen 4. Zum Schließen des Richtapparates wird der Bedienungshebel 13 aus der praktisch senkrechten Offenstellung in die waagerechte Stellung verschwenkt, wobei die beiden Körperteile 2, 3 aufgrund der Exzenter- und Zugstangenverbindung entgegen der Kraft der Schraubenfedern 7 aufeinanderzu bewegt werden, bis die Blattfeder 18 in die Quernuten 15 in den Führungsbolzen 4 einrastet. In dieser Raststellung sind die beiden Körperteile 2, 3 und damit auch deren Richtrollen 9 in einer definierten Null-Lage angeordnet. Zum Öffnen des Richtapparates drückt man auf die Druckkappen 21 und damit auf die Entriegelungs-stifte 20 und damit auf die Blattfeder 18 und bewegt deren freie Enden 16, 16' aus den Quernuten 15 in den Führungsbolzen 4, so daß die Schraubenfedern 7 - gegebenen-falls durch unterstützende Bewegung des Bedienungshebels 13 - den Richtapparat öffnen und in der Offenstellung halten. Das Schließen erfolgt durch einfaches Herunterklappen des Bedienungshebels 13, bis die Blattfeder 18 wieder in die Quernuten 15 der Führungsbolzen 4 einschnappt.First of all, the straightening apparatus is in a defined open position by means of the
Die Schutzhaube kann auch seitliche Querwände 22 mit einem Schlitz 23 oder einer Buchse bzw. Öse zur Führung oder zum Durchgang eines Richtgutes aufweisen. Hierdurch wird ein nahezu geschlossener Richtraum geschaffen, der vor einer Verschmutzung von außen weitgehend geschützt ist.The protective hood can also have lateral
Um den Staub, der durch das Berühren des Richtgutes mit den Richtrollen entsteht, zu entfernen, kann der Richtraum an eine Vakuumquelle (nicht dargestellt) angeschlossen sein, wobei vorzugsweise die Absaugöffnungen in Bewegungsrichtung des Richtgutes in unmittelbarer Nähe hinter dem jeweiligen Berührungspunkt von Richtrolle und Richtgut angeordnet sind.In order to remove the dust that results from touching the leveling material with the leveling rollers, the leveling room can be connected to a vacuum source (not shown), the suction openings in the direction of movement of the leveling material preferably being in the immediate vicinity behind the respective contact point between the leveling roller and leveling material are arranged.
Dadurch, daß praktisch alle beweglichen Teile durch die Schutzhaube, die Körperteile bzw. die Schutzhülsen abgedeckt sind, ist der Richtapparat weitgehend vor Verschmutzung geschützt, so daß lange Standzeiten möglich sind. Die jeweils reproduzierbare Null-Lage gewährleistet über lange Zeiträume eine gleichbleibende hohe Qualität, da die Schließstellung exakt definiert ist und es auch bleibt.The fact that practically all moving parts are covered by the protective hood, the body parts or the protective sleeves, the straightening apparatus is largely protected against contamination, so that long service lives are possible. The reproducible zero position guarantees consistently high quality over long periods of time, since the closed position is precisely defined and remains so.
