Description

Copper wire tinning stack

Technical Field

The invention relates to the technical field of copper wire processing, in particular to a copper wire tinning device.

Background

Copper is widely used in the fields of electronic information, lubrication, catalysis, metallurgy, and the like because of its excellent properties and low price. However, copper is very easily oxidized in air, and the finer the particle size, the more severe the oxidation. The tinned copper wire has the excellent characteristics of attractive appearance, high tensile strength, weldability, ageing resistance and the like, and is widely applied to industrial production and daily life, and the inert metal layer coated on the tinned copper wire not only can remarkably improve the oxidation resistance of copper, but also can better keep the conductivity of the copper. Although tin is not an inert metal and is more reactive than copper, tin is stable in air at normal temperature, and a dense oxide film is generated on the surface of tin to prevent the tin from being oxidized continuously. Thus, tin plating the copper surface may improve the oxidation resistance of the copper to some extent. The tin-plated copper has good stability, conductivity, wear resistance, corrosion resistance and electromagnetic shielding property, and has good application prospect.

The production process of the hot tinned copper wire in the traditional process comprises eight processes of paying off, annealing, acid washing, tinning, cooling, traction, guide shaft oil adding, tin ash reduction, winding and arranging and the like. The existing tinning processing method of the copper wire generally comprises the following steps: set up one row of perpendicular decurrent and insert the depression bar of tin liquor liquid level in the tinning bath of tinning machine, send into the copper line afterwards and push down by the depression bar in the tinning bath and tin-plate, the copper line of depression bar both sides is certain angle. When the method is used for tinning the copper wire, the compression bar is directly fixed on the copper wire, so that the resistance generated in the tinning process is overlarge, the resistance of a row wire of the copper wire is increased, and the phenomena of uneven tinning and broken wire and broken line generation of the copper wire are easily caused. In addition, in the actual operation process of copper wire tinning machine, because the tin liquor pond all is open structure generally, the tin liquor in the tin liquor pond is easily by the oxygen oxidation in the air to the effect of tinning has been influenced.

Some current patent technical scheme equipment can tin-plating many copper lines, and degree of automation is high, but still have some shortcomings, the ball of inlet assembly can cause the damage at copper line removal in-process, the ball is little for point contact frictional force with copper line contact mode, can't guarantee that copper line even migration can all make the adhesion effect of tin poor, and design complicacy power consumption height brings the degree of difficulty to later maintenance, does not set up the tin pig and melts the device and handle the reduction of tin dross, causes the jam easily.
