Description

Die Erfindung betrifft einen Richtapparat für drahtförmiges, mehrdrahtförmiges oder rohrförmiges Richgut mit mehreren in zwei parallelen Ebenen angeordneten drehbaren Richtrollen, deren Drehachsen in Kassetten gelagert sind, die in einem Gehäusehalter angeordnet sind. Hierbei können die Kassetten beider Ebenen unbeweglich sein oder es können die Kassetten einer Ebene oder auch beider Ebenen mittels einer Verstelleinrichtung verstellbar angeordnet sein.The invention relates to a straightener 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 stored in cassettes which are arranged in a housing holder. Here, the cassettes of both levels can be immovable or the cassettes of one level or both levels can be arranged to be adjustable by means of an adjusting device.

Ein solcher Richtapparat mit in einer Ebene verstellbaren Kassetten ist aus der DE 32 26 665 C2 bekannt.Such a straightening apparatus with cassettes adjustable in one plane is known from DE 32 26 665 C2.

Hierbei sind die Kassetten rechteckig gestaltet und weisen Nuten auf, in die Stifte eingreifen, an denen sie geradgeführt werden. Die Stifte liegen mit ihren Enden in Nuten in der oberen und unteren Deckplatte eines mehrteiligen Gehäusehalters, wodurch es möglich wird, die Kassetten gegeneinander zu verspannen. Die Kassetten der einen Ebene sind derart angeordnet, daß sie sich jeweils gegen eine Feder abstützen, die die Kassette gegen eine gegenüberliegend angeordnete Zustellschraube drückt. Durch Herein- oder Herausschrauben der Zustellschraube kann die Kassette und damit ihre Richtrolle gegen das Richtgut oder weg vom Richtgut verstellt werden.Here, the cassettes are rectangular and have grooves in which pins engage, on which they are guided in a straight line. The ends of the pins lie in grooves in the upper and lower cover plates of a multi-part housing holder, which makes it possible to clamp the cassettes against one another. The cassettes of the one level are arranged in such a way that they are each supported against a spring which presses the cassette against an opposing feed screw. By screwing the delivery screw in or out, the cassette and thus its straightening roller can be adjusted against the straightened goods or away from the straightened goods.

Eine derartige Anordnung der Kassetten ist relativ kompliziert und damit arbeitsaufwendig zusammenzubauen und erfordert auch ein gewisses Spiel bzw. bedingt Verspannungen, die jeweils eine neue Justierung der Kassetten bei einem notwendigen Wechsel der Richtrollen, z. B. beim Austausch der Richtrollen infolge von Verschleiß oder bei Änderungen der Größe für die Bearbeitung anderer Materialien.Such an arrangement of the cassettes is relatively complicated and thus laborious to assemble and also requires a certain amount of play or conditional tension, each of which requires a new adjustment of the cassettes at one necessary change of straightening roles, e.g. B. when replacing the straightening rollers due to wear or changes in size for processing other materials.

Aufgabe der Erfindung ist es, einen Richtapparat der eingangs genannten Art dahingehend zu verbessern, daß einerseits die Kassetten ohne großen Aufwand ausgewechselt werden können und daß andererseits eine hohe Präzision beim Richten und hohe Standzeiten gewährleistet sind, wobei auch das notwendige Spiel minimiert und die Präzision der reproduzierbaren Einstellung erhöht sein soll.The object of the invention is to improve a straightening apparatus of the type mentioned in such a way that, on the one hand, the cassettes can be exchanged without great effort and, on the other hand, a high level of precision in straightening and long tool life are ensured, the play required being minimized and the precision of reproducible setting should be increased.

Diese Aufgabe wird durch einen Richtapparat mit den Merkmalen des Anspruchs 1 bzw. des Anspruchs 2 gelöst.This object is achieved by a straightening apparatus with the features of claim 1 and claim 2.

Durch die Kassetten mit hohlzylindrischem Gehäuse ist es möglich, diese leicht austauschbar in einfach herzustellenden, exakt zu positionierenden Passungsbohrungen praktisch ohne Spiel anzuordnen, womit eine hohe reproduzierbare Genauigkeit gewährleistet und eine einfache Herstellung gegeben ist.The cassettes with a hollow cylindrical housing make it possible to arrange them easily replaceable in easily produced, precisely positioned fitting bores with practically no play, which ensures high reproducible accuracy and simple production.

Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the invention can be found in the subclaims.

Nachstehend wird die Erfindung an einem Ausführungsbeispiel unter Bezug auf die schematische Zeichnung näher erläutert. Es zeigt

The invention is explained in more detail using an exemplary embodiment with reference to the schematic drawing. It shows
Fig. 1

Der in Fig. 1 dargestellte Richtapparat weist in zwei parallelen Ebenen A und B angeordnete Richtrollen 1 auf, deren Drehachsen 2 in Kassetten 3 drehbar gelagert sind.The straightening apparatus shown in FIG. 1 has straightening rollers 1 arranged in two parallel planes A and B, the axes of rotation 2 of which are rotatably mounted in cassettes 3.

Eine Kassette 3 besteht nach dem Ausführungsbeispiel gemäß Fig. 3 aus einem Hohlzylinder 3', der an einer Seite durch einen Deckel 4 verschlossen ist und in dessen offenes Ende die die Richtrolle 1 tragende Drehachse 2 eingeführt ist. Die Drehachse 2 ist zur axialen Abstützung mittels eines Kugellagers 5 am deckelseitigen Ende der Kassette 3 gelagert, wobei die Laufbahn für die Kugeln 6 einerseits im Hohlzylinder 3' andererseits in der Drehachse 2 ausgeführt ist. Zur radialen Abstützung der Drehachse 2 sind im oberen Teil des Hohlzylinders 3' Nadellager 7 direkt zwischen der Innenwand des Hohlzylinders 3' und der Drehachse 2 angeordnet.According to the exemplary embodiment according to FIG. 3, a cassette 3 consists of a hollow cylinder 3 ', which is closed on one side by a cover 4 and in whose open end the axis of rotation 2 carrying the leveling roller 1 is inserted. The axis of rotation 2 is supported for axial support by means of a ball bearing 5 at the end of the cassette 3 on the cover side, the track for the balls 6 being executed in the hollow cylinder 3 'on the one hand and in the axis of rotation 2 on the other hand. For radial support of the axis of rotation 2, needle bearings 7 are arranged in the upper part of the hollow cylinder 3 'directly between the inner wall of the hollow cylinder 3' and the axis of rotation 2.

Im Ausführungsbeispiel weist die Richtrolle 1 an ihrer der Kassette 3 zugewandten Unterseite eine Ringnut 8 auf, die dazu bestimmt ist, das obere offene Ende des Hohlzylinders 3' aufzunehmen. Durch diese Anordnung ist eine Labyrinthdichtung erzeugt, die den Einsatz eines Richtapparates mit derartigen Kassetten auch in feuchten und staubigen Räumen ermöglicht. Dadurch werden die Lager der Drehachse vor Schmutz geschützt, was deren Lebensdauer erhöht. Durch die direkte Anordnung des Axialkugellagers und der Radiallager, d. h. ohne Außen- und Innenring, wird das Spiel minimiert.In the exemplary embodiment, the straightening roller 1 has on its underside facing the cassette 3 an annular groove 8 which is intended to receive the upper open end of the hollow cylinder 3 '. This arrangement produces a labyrinth seal which enables the use of a straightener with such cassettes, even in damp and dusty rooms. This protects the bearings of the axis of rotation from dirt, which increases their service life. Due to the direct arrangement of the thrust ball bearing and the radial bearing, i. H. without outer and inner ring, the game is minimized.

Der Deckel 4 der Kassette 3 kann auch einstückig mit dem Hohlzylinder 3' ausgeführt sein. Die Verbindung der Richtrolle 1 mit ihrer Drehachse 2 kann auf beliebige Art und Weise, z. B. auch durch Kleben erfolgen, was es ermöglicht, die Richtrollen 1 ohne wesentlichen Aufwand von der Drehachse 2 zu entfernen und durch neue Richtrollen 1 oder durch Richtrollen 1 mit anderen Durchmessern und/oder Einstichen auszutauschen, d. h. es ist nicht notwendig, aber möglich, die gesamte Kassette 3 auszuwechseln.The lid 4 of the cassette 3 can also be made in one piece with the hollow cylinder 3 '. The connection of the straightening roller 1 with its axis of rotation 2 can in any way, for. B. also be done by gluing, which makes it possible to remove the straightening rollers 1 from the axis of rotation 2 without significant effort and to replace them by new straightening rollers 1 or by straightening rollers 1 with other diameters and / or recesses, ie it is not necessary, but possible, replace the entire cassette 3.

Die Kassetten 3 sind in der Ebene A in einem Gehäusehalter 9 in darin ausgeführten Passungsbohrungen 10 angeordnet, deren Durchmesser derart gewählt ist, daß die hohlzylindrischen Kassetten 3 gerade ohne Spiel eingeführt werden können. Da derartige Passungsbohrungen 10 sehr exakt und leicht ausgeführt werden können, ist hierdurch auf einfache Art eine hohe Präzision der Anordnung der Kassetten 3 gewährleistet, und zwar auch bei jedem Austausch. Im Ausführungsbeispiel sind in der Ebene B die Kassetten 3 in Passungsbohrungen 10' angeordnet, die in einem geführten beweglichen Nutenstein 11 ausgeführt sind. Der Nutenstein 11 weist eine Gewindebohrung 12 auf, in die eine Verstellspindel 13 eingreift. Das freie Ende der Verstellspindel 13 ist durch eine Wand 14 des Gehäusehalters 9 geführt und trägt einen Verstellknopf 15. Der Verstellknopf 15 ist auf der Verstellspindel 13 axial beweglich, aber drehfest angeordnet. Innerhalb des Stellknopfes 15 ist auf der Verstellspindel 13 eine Schraubenfeder 16 angeordnet, die sich an einem Ende gegen einen Vorsprung des Verstellknopfes 16 und am anderen Ende gegen eine Scheibe 17 abstützt, die sowohl am Verstellknopf 15 als auch an der Verstellspindel 13, z. B. durch eine Schraube 18, festgelegt ist. Durch diese Anordnung der Schraubenfeder 16 wird der Verstellknopf 15 somit gegen die Wand 14 des Gehäusehalters 9 vorgespannt.The cassettes 3 are arranged in the plane A in a housing holder 9 in fitting bores 10 executed therein, the diameter of which is selected such that the hollow cylindrical cassettes 3 can be inserted without play. Since such fitting bores 10 can be carried out very precisely and easily, this ensures a high level of precision in the arrangement of the cassettes 3 in a simple manner, even with every exchange. In the exemplary embodiment, the cassettes 3 are arranged in fitting bores 10 ′ in the plane B, said bores being embodied in a guided movable sliding block 11. The sliding block 11 has a threaded bore 12 into which an adjusting spindle 13 engages. The free end of the adjusting spindle 13 is guided through a wall 14 of the housing holder 9 and carries an adjusting knob 15. The adjusting knob 15 is axially movable on the adjusting spindle 13, but is non-rotatably arranged. Inside the adjusting knob 15, a helical spring 16 is arranged on the adjusting spindle 13, which is supported at one end against a projection of the adjusting knob 16 and at the other end against a disk 17, which is attached to both the adjusting knob 15 and the adjusting spindle 13, e.g. B. is fixed by a screw 18. By this arrangement of the coil spring 16, the adjusting button 15 is thus biased against the wall 14 of the housing holder 9.

Im Ausführungsbeispiel weist die Wand 14 im Bereich der Anlagefläche des Verstellknopfes 15 eine Ausnehmung auf, in der eine Gummischeibe 19 angeordnet ist. Die Gummischeibe 19 dient, zusätzlich zum Andruck durch die Schraubenfeder 16, der Reibungserhöhung, so daß sich auch bei stärkeren Vibrationen während der Arbeit des Richtapparates der Verstellknopf 15 nicht selbständig verstellen kann. Anstelle einer Ausnehmung kann ein reibungserhöhendes Material, z. B. auch ein Kunststoff, Leder o. dgl. auch direkt auf den Verstellknopf 15 und/oder direkt auf der Wand 14 aufgebracht sein. Anstelle der Verwendung eines anderen Materials können auch zwischen Wand und Knopf andere die Reibung erhöhende Maßnahmen z. B Rastverbindungen (nicht dargestellt) vorgesehen sein. Aufgrund der Möglichkeit der axialen Bewegung des Verstellknopfes 15 entgegen dem Druck der Schraubenfeder 16 kann die Reibungsverbindung gelöst werden, dies ermöglicht eine leichte und damit auch eine sehr präzise Verstellung der Verstellspindel 13 und damit auch des Nutensteins 11. Wenn keine exakte Verstellung notwendig ist, kann auch auf die axiale Verstellung des Verstellknopfes 15 verzichtet werden; es ist dann nur notwendig, mehr Kraft zur Verstellung des Verstellknopfes 15 aufzubringen, um die Reibungsverbindung zu überwinden.In the exemplary embodiment, the wall 14 has a recess in the area of the contact surface of the adjusting knob 15, in which a rubber disk 19 is arranged. The rubber washer 19 serves, in addition to the pressure by the helical spring 16, to increase the friction, so that the adjusting button 15 cannot be adjusted independently even when there are strong vibrations during the work of the straightening apparatus. Instead of a recess, a friction-increasing material, e.g. B. also a plastic, leather or the like can also be applied directly to the adjustment button 15 and / or directly on the wall 14. Instead of using a different material, other measures increasing the friction can also be made between the wall and the button. B snap-in connections (not shown) be provided. Due to the possibility of the axial movement of the adjusting knob 15 against the pressure of the helical spring 16, the friction connection can be released, this enables an easy and thus also a very precise adjustment of the adjusting spindle 13 and therefore also of the sliding block 11. If no exact adjustment is necessary, the axial adjustment of the adjusting knob 15 can also be dispensed with; it is then only necessary to apply more force to adjust the adjusting knob 15 in order to overcome the frictional connection.

Durch eine beliebige bekannte axiale Führung des Nutensteins 11 und die entsprechende Wahl der Steigung des Gewindes kann eine sehr präzise, leicht wiedereinstellbare Stellung der Kassetten 3 und damit der Richtrollen 1 der Ebene B gewährleistet werden.Any known axial guidance of the sliding block 11 and the corresponding choice of the pitch of the thread can ensure a very precise, easily re-adjustable position of the cassettes 3 and thus the leveling rollers 1 of the plane B.

Im Falle des Einsatzes unter höchsten Beanspruchungen und gegebenenfalls zur Erhöhung der Lebensdauer kann den Lagern der Drehachse 2 periodisch ein Schmiermittel zugeführt werden, z. B. durch ein verschließbares Bohrungssystem (nicht dargestellt) in der Drehachse 2 bei Stillstand des Richtapparates. Es ist auch möglich, innerhalb der Wand des Hohlzylinders 3' ein Schmiermitteldepot mit Ausgangsöffnungen zu den Lagern 5, 7 vorzusehen, die gegebenenfalls auch an ein Zufuhrleitungssystem innerhalb des Gehäusehalters 9 angeschlossen sein können (beides nicht dargestellt).In the case of use under the highest loads and possibly to increase the service life, the bearings of the axis of rotation 2 can be periodically supplied with a lubricant, e.g. B. by a closable drilling system (not shown) in the axis of rotation 2 when the straightener is at a standstill. It is also possible to provide a lubricant depot with outlet openings to the bearings 5, 7 within the wall of the hollow cylinder 3 ', which can optionally also be connected to a supply line system within the housing holder 9 (both not shown).
