Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Einrichtung für das Behandeln von Textilfasern, vorzugsweise aus Wolle, Baumwolle oder Fasern aus natürlichen, wie synthetischen Polymeren, wie z.B. eine in Form eines Rings ausgebildete, eine Ganzstahldraht-Garnitur, insbesondere Open-end-Garnitur umfassende Auflösewalze von insbesondere der Verbesserung des Stapels von Rohfasermaterial dienenden Karden oder z. B. außenseitig Drahtsektionen umfassende Rundkämme von insbesondere der Parallelisierung der Einzelfasern von Faservliesen dienenden Kämmaschinen, bei denen die Drahtspitzen der Ganzstahldraht-Garnitur bzw. der mindestens ersten Sektion der Drahtabschnitte der Rundkämme einem Härtevorgang unterzogen werden. The invention relates to a method of manufacture a device for treating textile fibers, preferably made of wool, cotton or natural fibers, such as synthetic polymers, e.g. one in shape a ring formed, an all-steel wire set, in particular Open-end set comprising opening roller in particular improving the stack of raw fiber material serving cards or z. B. Outside wire sections comprehensive Round ridges, in particular the parallelization of the Single fibers of nonwoven combing machines, in which the wire tips of the all-steel wire set or at least first section of the wire sections of the round combs undergo a hardening process.
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.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 to be determined. The formation of the ring made of aluminum turned out to be cheaper than steel, because Use of aluminum by pressurizing the area the groove ensures a more secure anchoring of the wire is. However, the following is problematic the manufacture of the ring steel wire unit required Hardening the tips of the wound wires z. B. by electrochemical Coating.
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 beim Verfahren der genannten Art im wesentlichen dadurch gelöst, daß die Drähte bzw. Drahtsektionen vor dem Verankern an dem Ring bzw. an dem Rundkammträger als gesondertes Bauteil nach dem üblichen Stanzvorgang zur Ausbildung der Zähne mit anschließender Zahndurchhärtung zur Erhöhung der Zahnfestigkeit und elektrochemischem Entgraten sodann in ihrer Form durch Vorbiegen an die des Rings bzw. Rundkammträgers angepaßt werden, bevor sie einem Oberflächenhärtungsprozeß unterworfen und sodann auf dem Ring bzw. dem Rundkammträger verankert werden. 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 carried out in the process of the type mentioned essentially solved in that the wires or wire sections before anchoring to the ring or to the round comb support as a separate component after the usual punching process for the formation of the teeth with subsequent tooth hardening to increase tooth strength and electrochemical deburring then in shape by pre-bending to that of the ring or circular comb carrier are adjusted before they start a surface hardening process subjected and then on the ring or the circular comb support. Created in this way Opening rollers are characterized by high wear resistance the sawtooth tips also for a relatively long time Operating times. This also applies to round combs, their highly stressed foremost first wire sections as separate Components are subjected to a hardening process after their shape has been adapted can be.
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 um-faßt. 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 includes 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.
