Description

Die Erfindung besieht sich auf eine Vorrichtung zur Feuerdickverzinnung von Schalt- und Bauelementanschlußdrähten aus Kupfer, Zinn, Bronze und Nickel, bei der der zu verzinnende Draht nacheinander ein Säurebeizbad, ein Zinn- oder Zinnlegierungsbad mit einer ersten Umlenkrolle aus einem nichtmetallischen Werkstoff, eine als Abstreifer wirkende iVellenprofildüse und eine Kühlstrecke mit einer weiteren Umlenkrolle durchläuftThe invention relates to a device for Thick hot tinning of switching and component connection wires made of copper, tin, bronze and nickel the wire to be tinned with an acid pickling bath, a tin or tin alloy bath, one after the other a first deflection roller made of a non-metallic material, an iVelle profile nozzle acting as a scraper and passes through a cooling section with a further deflection roller

Bei der Feuerdickverzinnung von Schalt- und Bauelementeanschlußdrähten unter Verwendung von Wellenprofildüsen ali Abstreifer ist ein möglichst ruhiger und schwingungsfreier £)rahtla?5 zwischen der Umlenkrolle im Zinnbad und der Umlenkrolle nach der Kühlstrecke zur Erzielung zentrisch vereinter 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.When hot-dip tinning of switching and component connection wires using Wave profile nozzles ali wipers are as quiet and vibration-free as possible a rahtla? 5 between the Deflection roller in the tin bath and the deflection roller after the cooling section to achieve centrally united wires necessary. Wire vibrations and changes in the position of the wire in this area can lead to a Brief contact between the wire and 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 Temperaturbeständigkeit, Verschleißfestigkeit, mechanischer Belastbarkeit geringer Lagerreibung und hoher Lagergenauigkeit nur mit Einschränkungen.The pulleys made of aluminum oxide or previously used for guiding the wire in the tin bath Stainless steel (V2A) meet the simultaneous requirement for temperature resistance, wear resistance, mechanical load capacity, low 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.Deflection pulleys made of aluminum oxide, which are often used in wire tinning plants, have due to the thermal shock in connection with mechanical stress on the roller none satisfactory lifespan.

Verschiedene anderere Möglichkeiten wie z.B.Various other options such as

Lagerung auf Spitzen, Wälzlagerung mit Druckölspülung und eine Lagerung außerhalb des Zinnbades konnten ebenfalls keine befriedigenden Ergebnisse erzielen.Bearings on tips, roller bearings with pressurized oil flushing and storage outside the tin bath also failed to produce satisfactory results achieve.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Umlenkrolle und Umlenkrollenlagerung zu entwickeln, die folgende Forderungen zufriedenstellend erfüllen:
Temperaturschockbeständigkeit 20/3500C (Emtauchen der Umlenkrolle in das Zinnbad), Nichtbenetzbarkeit durch Zinn- und Zinn-Blei-Schmelzen, mechanische Festigkeit (auch bei Schlagbeanspruchung), geringe Lagerreibung im Temperaturbereich von 200C bis 3500C im eingetauchten Zustand und an Luft geringes
The present invention is therefore based on the object of developing a deflection roller and deflection roller bearing that satisfactorily meet the following requirements:
Temperature shock resistance 20/350 0 C (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 0 C to 350 0 C when immersed and little in air

'S Lagerspiel, geringe Wärmedehnung, kein Verschleiß an Lager- und Anlaufflächen, kein Verschleiß in der Drahtführungsrille und einfache Handhabung.'S bearing clearance, low thermal expansion, no wear on Bearing and contact surfaces, no wear in the wire guide groove and easy handling.

Gemäß der Erfindung wird die Aufgabe dadurch gelöst daß die Umlenkrolle im Zinn- oder Zinnlegierungsbad sowie ihre Lagerung aus Siliziumnitrid (S13N4) bestehen.According to the invention, the object is achieved in that the deflection roller in the tin or tin alloy bath and their bearings are made of silicon nitride (S13N4).

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 provide the role with a stainless steel armor (V2A) so that every Avoid damage caused by impact stress in the event of damage.

Alle Gleitflächen bzw. Gleitpaarungen sind durch Teile aus Siliziumnitrid gebildet Der Verschleiß zwischen Lagerzapfen und Umlenkrolle sowie zwischen Umlenkrolle und seitlicher Anlauffläche wird hierdurch vernachlässigbar gering.All sliding surfaces or sliding pairs are formed by parts made of silicon nitride. Wear between the bearing pin and the deflection roller and between the deflection roller and the lateral contact surface negligibly small.

Die Umlenkrolle gemäß der Erfindung gewährleistet einen ruhigen, schwingungsfreien Drahtlauf, der die Verzinnungsqualität feuerdickverzinnter Drähte bei Verwendung von Wellenprofildüsen positiv beeinflußtThe pulley according to the invention ensures a quiet, vibration-free wire run that the Tinning quality of hot-dip tinned wires positively influenced when using corrugated profile nozzles

The axis 14 around which the deflection roller 11 rotates is also made of silicon nitride. The axis 14 is attached to the receiving fork 13. The receiving fork 13 consists of non-wettable material, e.g. B. made of V2A steel. With 15 sliding plates are designated, which are also made of silicon nitride. The sliding plates 15 are secured against rotation by the cylinder pins 16
