Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung
einer Einrichtung für das Behandeln von Textilfasern,
nach dem Oberbegriff des Patentanspruchs 1. The invention relates to a method of manufacture
a device for treating textile fibers,
according to the preamble of
Bei der Fertigung von ringförmigen Auflösewalzen der
vorgenannten Art ist es üblich, zur Vermeidung von kostspieligen
einstückigen Stahlring-Stahlzahndraht-Ausführungen den
Stahlzahndraht mit seinem Fuß in einer an der Oberfläche des
Rings vorgesehenen schraubenwendelförmigen Nut durch Einziehen
festzulegen. Die Ausbildung des Rings aus Aluminium hat sich
dabei als günstiger erwiesen als die aus Stahl, da bei Verwendung
von Aluminium durch Druckbeaufschlagung des Bereichs der
Nut eine sicherere Verankerung des Drahts gewährleistet ist.
Problematisch ist allerdings die im Anschluß an die Herstellung
der Ring-Stahldraht-Einheit erforderliche Härtung der
Spitzen der aufgezogenen Drähte z. B. durch elektrochemische
Beschichtung. Ferner sind Verfahren nach dem Oberbegriff des
Patentanspruchs 1 aus der WO 91/15605 bekannt. Ferner ist aus
der WO 94/05837 eine Auflösewalze bekannt, bei der die äußeren
Teile der Bearbeitungselemente mit einer reibungsverringernden
Beschichtung versehen sind.In the manufacture of ring-shaped opening rollers
aforementioned type, it is common to avoid costly
one-piece steel ring steel toothed wire versions
Steel toothed wire with its foot in one on the surface of the
Helical groove provided around the ring by pulling in
set. The formation of the ring from aluminum has
proven to be cheaper than the steel because in use
of aluminum by pressurizing the area of the
Only a more secure anchoring of the wire is guaranteed.
However, the problem after the production is problematic
the hardening of the ring steel wire unit
Tips of the wound wires z. B. by electrochemical
Coating. Furthermore, methods according to the preamble of
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, mit dessen Hilfe unter Beseitigung der genannten Nachteile auf relativ einfache Weise Auflösewalzen bzw. Rundkämme von Kämmaschinen mit vergleichsweise höheren Standzeiten herstellbar sind.The invention has for its object a method to create, with the help of eliminating the aforementioned Disadvantages in a relatively simple way opening rollers or round combs of combing machines with comparatively higher ones Downtimes can be produced.
Diese Aufgabe wird durch die im kennzeichnenden Teil
des Anspruchs 1 angegebene Weiterbildung der bekannten Verfahren
gelöst. Auf diese Weise geschaffene Auflösewalzen zeichnen
sich durch hohe Verschleißfestigkeit der Sägezahnspitzen auch
über verhältnismäßig lange Einsatzzeiten aus. Dies gilt auch
für Rundkämme, deren höchstbelastete vorderste erste Drahtsektionen
als gesonderte Bauteile nach ihrer Formanpassung einem
Härtungsprozeß unterzogen werden können. This task is accomplished by the in the characterizing part
of
Als in fertigungstechnischer Hinsicht besonders vorteilhaft hat es sich erfindungsgemäß erwiesen, wenn der auf das Stanzen und das elektrochemische Entgraten der Sägezähne sowie den Vorbiegevorgang des gezahnten Drahtes bzw. der Drahtsektionen entsprechend der gekrümmten Oberfläche des Rings bzw. Rundkammträgers folgende Oberflächenhärtungsprozeß eine Beschichtung durch Auftrag einer Diamant/Ni-Schicht umfaßt. Dabei ist es besonders günstig, wenn die Drähte zunächst einem wendelförmigen Vorbiegevorgang und anschließend dem Oberflächenhärtungsprozeß im Bereich ihrer Sägezähne unterworfen und sodann auf den Ring aufgezogen werden.As particularly advantageous in terms of manufacturing technology it has proven according to the invention if the on punching and electrochemical deburring of the saw teeth and the pre-bending process of the toothed wire or the Wire sections corresponding to the curved surface of the Ring or round comb carrier following surface hardening process a coating by applying a diamond / Ni layer. It is particularly beneficial if the wires are first a helical pre-bending process and then subjected to the surface hardening process in the area of their saw teeth and then be wound on the ring.
Beim erfindungsgemäßen Verfahren ist ein solches schraubenwendelförmiges Vorbiegen des Sägezahndrahtes von Vorteil, daß letzterer in entspanntem Zustand einen Innendurchmesser aufweist, der angenähert dem Außendurchmesser des zylindrischen Rings entspricht, so daß die Sägezahndrahtwendel auf den zylindrischen Ring aufschiebbar oder aber durch Einrollen in die Nut fixierbar ist. Die auf diese Weise gewissermaßen als Zwischenprodukt geschaffene Ganzstahldrahtwendel besitzt einen vergleichsweise geringen Raumbedarf und ermöglicht deshalb eine relativ bequeme Handhabung beim folgenden Aufziehen auf den den Auflösewalzengrundkörper bildenden Ring.Such is the case with the method according to the invention helical pre-bending of the sawtooth wire from Advantage that the latter has an inner diameter in a relaxed state having approximately the outer diameter of the corresponds to cylindrical ring, so that the sawtooth wire helix can be pushed onto the cylindrical ring or through Rolling into the groove can be fixed. That way, so to speak All-steel wire helix created as an intermediate product has a comparatively small space requirement and therefore allows a relatively convenient handling in the following Mount on the body forming the opening roller Ring.
Werden die Garnitur bildende Sägezahndrähte verwendet, die einen Fuß und ein von diesem ausgehendes Blatt mit einer Folge von Sägezähnen aufweisen, sowie eine am zylindrischen Ring außenseitig vorgesehene wendelförmige Nut, die einen durch zwei seitliche Stege begrenzten, etwa rechteckigen Querschnitt aufweist, der dem entsprechenden Querschnitt des in die Nut einführbaren Fußes des Sägezahndrahtes angepaßt ist, dann ist es erfindungsgemäß in weiterer Ausgestaltung sehr günstig, wenn zumindest der eine die Nut des Rings seitlich begrenzende Steg durch radiale Beaufschlagung eine solche Verformung erfährt, daß Ringmaterial aus dem Bereich des druckbeaufschlagten Steges in eine in einer Flanke des in die Nut eingeführten Fußes vorgesehene, sich über die gesamte Länge des Sägezahndrahtes erstreckende Längsrille hineingedrückt wird. Auf diese relativ einfache Weise läßt sich eine effektive mechanische Kopplung des Sägezahndrahtes mit dem Ring erreichen.If saw tooth wires are used to form the set, with a foot and a leaf that emanates from it have a sequence of saw teeth, and one on the cylindrical Ring provided on the outside helical groove, the one, approximately rectangular, delimited by two lateral webs Cross section that corresponds to the corresponding cross section of the adapted in the groove insertable foot of the sawtooth wire is, then it is according to the invention in a further embodiment very cheap if at least one of the grooves of the ring is on the side limiting web by radial loading such Deformation learns that ring material from the area of pressurized web in one in a flank of the in the Groove inserted foot provided over the entire Length of the sawtooth wire extending longitudinal groove pressed in becomes. In this relatively simple way, one can effective mechanical coupling of the sawtooth wire with the Reach the ring.
Um zunächst einmal die Sägezahndrahtwendel einfach und sicher in der Nut des Rings zu plazieren, ist das Verfahren weiterhin in vorteilhafter Weise gekennzeichnet durch Verwendung einer am Fuß des Sägezahndrahts seitlich angeformten Schulter zur radialen Beaufschlagung beim Eindrücken des vorgeformten Sägezahndrahtes in die Nut.To begin with, the sawtooth wire helix is simple and placing it securely in the groove of the ring is the procedure further characterized in an advantageous manner Use a molded on the side of the sawtooth wire Radial loading shoulder when pushing in pre-shaped sawtooth wire into the groove.
Ähnlich günstig ist die Erfindung bei einem Rundkammträger mit mehreren aufeinanderfolgenden Drahtsektionen praktizierbar, von denen die in Wirkrichtung vorderste, deren Zähne einen im Vergleich zu den Zähnen der nächsten sowie der folgenden Sektionen größeren gegenseitigen Abstand aufweisen, nach Herstellung in an die Krümmung des Rundkammträgers angepaßter Form vorzugsweise durch Aufkleben z. B. mittels eines Ein- oder Zwei-Komponenten-Klebers auf dem Rundkammträger festgelegt wird. Durch diese Verbesserung der ersten, vordersten Sektion wird in sehr günstiger Weise die Rundkammlebensdauer stark erhöht, da alle Sektionen etwa zum gleichen Zeitpunkt abgenützt sind, worauf dann der Wechsel des kompletten Kammes erfolgt.The invention is similarly cheap for a circular comb carrier practicable with several successive wire sections, of which the foremost in the direction of action, the Teeth one compared to the teeth of the next as well as the the following sections have a greater mutual distance, after production in adapted to the curvature of the circular comb carrier Form preferably by gluing z. B. by means of a One or two-component adhesive on the round comb carrier is set. By improving the first, foremost Section becomes the round comb life in a very favorable way greatly increased, since all sections at about the same time are worn out, whereupon the change of the complete Comb is done.

Außenfläche des zylindrischen Rings 1 eingedrehte wendelförmige
Nut 2 durch seitliche Stege 4 und 4' begrenzt ist, die
parallel zueinander verlaufen und sich zum quergerichteten
