Description
Vorrichtung zur FeuerdickverzinnungDevice for thick fire tinning
Die Erfindung bezieht sich auf eine Vorrichtung zur Feuerdickverzinnung von Schalt- und Bauelementeanschlußdrähten aus Kupfer, Zinn, Bronze und Nickel, bei der der zu verzinnende Draht nacheinander ein Säurebeizbad, ein Zinn- oder Zinnlegierungsbad mit einer ersten Umlenkrolle, eine als Abstreifer wirkende Wellenprofildüse und eine Kühlstrecke mit einer weiteren Umlenkrolle durchläuft.The invention relates to a device for hot-dip tin plating of switching and component connection wires made of copper, tin, bronze and nickel, in which the wire to be tinned is successively an acid pickling bath, a tin or tin alloy bath with a first deflection roller, a corrugated profile nozzle acting as a scraper and runs through a cooling section with a further deflection roller.
Bei der Feuerdickverzinnung von Schalt- und Bauelementeanschlußdrähten unter Verwendung von Wellenprofildüsen als Abstreifer ist ein möglichst ruhiger und schwingungsfreier Drahtlauf zwischen der Umlenkrolle im Zinnbad und der Umlenkrolle nach der Kühl strecke zur Erzielung zentrisch verzinnter Drähte erforderlich. Drahtschwingungen und Lageänderungen des Drahtes in diesem Bereich können zu einem kurzzeitigen Anliegen des Drahtes an den Stegen der Wellenprofildüse und damit unter ungünstigen Umständen zu Dünnstellen in der Zinnschicht führen.For thick fire tinning of switching and component connection wires using corrugated profile nozzles as scrapers is as quiet as possible and vibration-free wire run between the pulley in the tin bath and the pulley Required after the cooling section to achieve centrically tinned wires. Wire vibrations and changes in the position of the wire in this area can become a short-term concern of the wire on the webs of the corrugated profile nozzle and thus under unfavorable circumstances lead to thin spots in the tin layer.
Die bisher für die Drahtführung im Zinnbad verwendeten Umlenkrollen aus Aluminiumoxid oder Edelstahl (V2A) erfüllen die gleichzeitige Forderung nach Ternperatlrbeständigkeit, Verschleißfestigkeit, mechanischer Belastbarkeit, geringer Lagerreibung und hoher Lagergenauigkeit nur mit Einschänkungen.The pulleys previously used for guiding the wire in the tin bath made of aluminum oxide or stainless steel (V2A) meet the simultaneous requirement for Thermal resistance, wear resistance, mechanical load capacity, lower Bearing friction and high bearing accuracy only with restrictions.
Umlenkrollen aus Aluminiumoxid, die vielfach in Drahtverzinnungsanlagen eingesetzt werden, haben durch die Temperaturwechselbelastung in Verbindung mit mechanischer Beanspruchung der Rolle keine befriedigende Lebensdauer.Pulleys made of aluminum oxide, which are often used in wire tinning plants are used, have due to the thermal shock in connection with mechanical stress on the role does not have a satisfactory service life.
Verschiedene andere Möglichkeiten wie z.B. Lagerung auf Spitzen, Wälzlagerung mit Druckölspülung und eine Lagerung außerhalb des Zinnbades konnten ebenfalls keine befriedigenden Ergebnisse erzielen.Various other options such as bearing on tips, roller bearings with pressurized oil flushing and storage outside of the tin bath, none could either achieve satisfactory results.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Umlenkrolle und Umlenkrollenlagerung zu entwickeln, die folgende Forderungen zufriedenstelle erfüllen: Temperaturschockbeständigkeit 20/350 0c (Eintauchen der Umlenkrolle in das Zinnbad), Nichtbenetzbarkeit durch Zinn- und Zinn-Blei-Schmelzen, mechanische Festigkeit (auch bei Schlagbeanspruchung), geringe Lagerreibung im Temperaturbereich von 20 0C bis 350 0C im eingetauchten Zustand und an Luft, geringes Lagerspiel, geringe Wärmedehnung, kein Verschleiß an Lager- und Anlaufflächen, kein Verschleiß in der Drahtführungsrille und einfache Handhabung.The present invention is therefore based on the object of a To develop deflection roller and deflection roller bearing that satisfy the following requirements meet: temperature shock resistance 20/350 0c (immersion of the deflection roller in the tin bath), non-wettability by tin and tin-lead melts, mechanical Strength (even when exposed to impact), low bearing friction in the temperature range from 20 0C to 350 0C in the submerged state and in air, low bearing clearance, low thermal expansion, no wear on bearing and contact surfaces, no wear in the wire guide groove and easy to use.
Gemäß der Erfindung wird die Aufgabe dadurch gelöst, daß die Umlenkrolle im Zinn- oder Zinnlegierungsbad sowie ihre Lagerung aus Siliziumnitrid (Si3N4) bestehen.According to the invention, the object is achieved in that the deflection roller in the tin or tin alloy bath and their storage consist of silicon nitride (Si3N4).
Es ist besonders vorteilhaft, die Rolle mit einer Edelstahl-Panzerung (V2A) zu versehen, um auf Jeden Fall Beschädigungen durch Schlagbeanspruchungen zu vermeiden.It is particularly advantageous to have the role with a stainless steel armor (V2A) to be provided in order to avoid damage from impact stress in any case to avoid.
Alle Gleitflächen bzw. Gleitpaarungen sind durch Teile aus Siliziumnitrid gebildet. Der VerschleiB zwischen Lagerzapfen und Umlenkrolle sowie zwischen Umlenkrolle und seitlicher Anlauffläche wird hierdurch vernachlässigbar gering.All sliding surfaces or sliding pairs are made of silicon nitride by parts educated. The wear between the bearing journal and the deflection pulley and between the deflection pulley and the lateral contact surface is negligibly small as a result.
Die Umlenkrolle gemäß der Erfindung gewährreistet einen ruhigen, schwingungsfreien Drahtlauf, der die Verzinnungsqualität feuerdick- verzinnter Drähte bei Verwendung von Wellenprofildüsen positivbeeinflußt. Die Umlenkrolle gemäß der Erfindung unterliegt praktisch keinem Verschleiß und garantiert damit einen störungsfreien und über längere Zeit gleichmäßigen Betrieb von Drahtverzinnungsanlagen.The pulley according to the invention ensures a quiet, vibration-free Wire run that enhances the tinning quality tinned wires positively influenced when using corrugated profile nozzles. The pulley according to the Invention is practically not subject to wear and tear and thus guarantees trouble-free and even operation of wire tinning plants over a longer period of time.
Anhand der Zeichnung und eines Ausführungsbeispiels wird die Erfindung näher erläutert.The invention is based on the drawing and an exemplary embodiment explained in more detail.
In der Zeichnung ist die Umlenkrolle gemäß der Erfindung mit ihrer Lagerung und Halterung gezeigt. Mit 11 ist die Umlenkrolle aus Siliziumnitrid (Si3N4) und ihrer Umhüllung 12 aus Edelstahl (V2A) bezeichnet. Die Achse 14, um die sich die Umlenkrolle 11 dreht, besteht ebenfalls aus Siliziumnitrid. Die Achse 14 ist an der Aufnahmegabel 13 befestigt. Die Aufnahmegabel 13 besteht aus nichtbenetzbarem Material, z.B. aus V2A-Stahl. Mit 15 sind Gleitplatten bezeichnet, die ebenfalls aus Siliziumnitrid bestehen. Die Gleitplatten 15 sind durch die Zylinderstifte 16 gegen Verdrehen gesichert.In the drawing, the pulley according to the invention is with her Storage and bracket shown. With 11 the pulley is made of silicon nitride (Si3N4) and its casing 12 made of stainless steel (V2A). The axis 14 around which the pulley 11 rotates, also consists of silicon nitride. The axis 14 is attached to the receiving fork 13. The receiving fork 13 consists of non-wettable Material, e.g. made of V2A steel. With 15 sliding plates are designated, which also consist of silicon nitride. The slide plates 15 are supported by the cylinder pins 16 secured against twisting.
