Abstract
The invention relates to a piston type special electroplated lead and tin anode for chromium plating on the inner wall of an oil well pump cylinder. The anode comprises a round steel mandrel, wherein a lead and tin layer is electroplated on the round steel mandrel, and an upper supporting polytetrafluoroethylene cover and a lower supporting polytetrafluoroethylene cover are fixedly connected to the upper end and the lower end of the round steel mandrel where the lead and tin layer is electroplated, respectively. Four uniformly distributed arc-shaped bumps are machined on the side faces of the upper supporting polytetrafluoroethylene cover, and four uniformly distributed arc-shaped bumps are machined on the side faces of the lower supporting polytetrafluoroethylene cover; the upper and lower surfaces of the upper supporting polytetrafluoroethylene cover are polished in first arc-shaped structures and protrude outward relatively, the upper surface of the lower supporting polytetrafluoroethylene cover is polished in a second arc-shaped structure, and the lower part of the lower supporting polytetrafluoroethylene cover is machined in a cone-shaped structure. The piston type special electroplated lead and tin anode for chromium plating on the inner wall of the oil well pump cylinder provided by the invention not only enables the lead and tin layer to be good in compactness and high in conductive performance, but also can move up and down on the inner wall of the oil well pump cylinder, so that the electroplating quality is improved; the anode further can be repeatedly machined and used, the service life of the anode is prolonged, and the cost is lowered.
Description
Technical field
The present invention relates to a kind of lead plating tin anode, particularly a kind of oil pumping barrel inwall piston type chromium plating Special electric lead plating tin anode.
Background technology
Traditional anode typically uses casting method to make, and the method exists following defect: produce high temperature time 1, due to casting, easily causes the oxidation of round steel mandrel surface, affects plug and the electric conductivity of slicker solder layer.2, slicker solder easily produces hole, in use owing to by electrolytic corrosion, shortening the service life of lead-tin anode when casting.3., specialty casting prolong pressure processing charges higher, casting slicker solder layer puncture or conduct electricity bad in the case of, process can only be scrapped.
The patent " a kind of chromium on cavity of slender pipe special anode and chrome-plating method thereof " of Application No. " 201110213748.6 ", for slender rectangular tube inner chamber, uses Cr-plating Bath copper facing successively and slicker solder, and reaches chromium plating purpose by temperature control.Which and the present invention have similarity, are all to use plating mode to obtain.But its defect is, this anode product is that clamping is fixed on inside slender rectangular tube, hole inwall can be caused to exist and support print, have a strong impact on chromium plating quality.
Summary of the invention
The technical problem to be solved there is provided a kind of oil pumping barrel inwall piston type chromium plating Special electric lead plating tin anode, not only make slicker solder layer compactness fine, electric conductivity is strong, can also move up and down at oil pumping barrel inwall, improve electroplating quality, more can repeat processing to use, extend the service life of anode, cost-effective.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is:
A kind of oil pumping barrel inwall piston type chromium plating Special electric lead plating tin anode, it includes round steel plug, round steel plug is electroplate with slicker solder layer, and upper support tetrafluoro set and lower support tetrafluoro set are respectively fixedly connected with at the two ends up and down of the round steel plug being coated with slicker solder layer.Described upper support tetrafluoro set and lower support tetrafluoro set side are processed as four equally distributed arc-shaped protrusions, described upper support tetrafluoro set upper and lower surface polishing is the first convex structure, and it is relatively outwardly protruding, described lower support tetrafluoro set upper surface polishing is the second convex structure, and bottom is processed as cone-shaped structure.
Described upper support tetrafluoro set and lower support tetrafluoro set are concentric with oil pumping barrel steel pipe inner wall, and composition is slidably matched.
A kind of oil pumping barrel inwall piston type chromium plating Special electric lead plating tin anode that the present invention provides, by electroplating lead tin alloy after the rust cleaning of round steel mandrel surface, alloying component is 8% stannum and 92% lead, obtains one layer of 1.5-2mm thickness compactness slicker solder layer.Upper support tetrafluoro set and lower support tetrafluoro set, by being fixed on anode two ends after machining, owing to tetrafluoro set has the most wear-resisting and precaution, can make the effect of support set；Lead plating tin anode guarantees the concentricity of anode and pump barrel caliber when pump barrel inwall chromium plating simultaneously, it is ensured that the dimensional homogeneity of coating.
In use, using due to long-time, lead plating tin layers can progressively be lost, and when being lost to a certain extent, is processed on slicker solder layer surface and is totally again electroplated onto given size, reuse.
This practicality lead plating tin anode service life during practice uses is about 5 times of conventional anode.Thus it is substantially reduced production cost, also improve the quality of product simultaneously.
Accompanying drawing explanation
With embodiment, invention is described further below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the upper support tetrafluoro nested structure schematic diagram of the present invention.
