Abstract
The utility model provides a special slicker solder positive pole of electroplating of oil pumping pump barrel inner wall piston chromium plating, it includes the round steel plug, it has the slicker solder layer to electroplate on the round steel plug supports tetrafluoro cover and under bracing tetrafluoro on, and overlaps respectively the upper and lower both ends of fixed connection at the round steel plug that plates the slicker solder layer. Support the tetrafluoro cover on and process the arc processes who is four evenly distributed with under bracing tetrafluoro cover side, it sheathes the lower surface in and polishes to first round arc structure to support the tetrafluoro on to it is opposite outer outstanding, under bracing tetrafluoro cover upper surface polish to second circle arc structure, lower part processing is coniform structure. The utility model relates to a special slicker solder positive pole of electroplating of oil pumping pump barrel inner wall piston chromium plating not only makes slicker solder layer compactness fine, and electric conductive property is strong, can also reciprocate at oil pumping pump barrel inner wall, improves and electroplates the quality, more can use by repeated machining, and extension anodal life practices thrift the cost.
Description
Technical field
The utility model 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 generally adopts teeming practice to make, and the method exists following defect: 1, produce high temperature due to during casting, easily cause round steel mandrel surface to be oxidized, affect the electroconductibility of plug and slicker solder layer.2, slicker solder easily produces hole when casting, and in use owing to being subject to electrolytic corrosion, shortens the work-ing life of lead-tin anode.3., that pressure processing charges is prolonged in specialty casting is higher, when casting slicker solder layer punctures or conducts electricity bad, can only scrap process.
Application number be the patent " a kind of chromium on cavity of slender pipe special anode and chrome-plating method thereof " of " 201110213748.6 " for slender rectangular tube inner chamber, adopt Cr-plating Bath copper facing and slicker solder successively, and reach chromium plating object by temperature control.Which and the utility model have similarity, are all to adopt plating mode to obtain.But its defect is, this anode product is that clamping is fixed on slender rectangular tube inside, hole inwall can be caused to exist and support print, have a strong impact on chromium plating quality.
Summary of the invention
Technical problem to be solved in the utility model 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, 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 work-ing life of anode, cost-saving.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of oil pumping barrel inwall piston-type chromium plating Special electric lead plating tin anode, it comprises round steel plug, round steel plug is electroplate with slicker solder layer, and upper support tetrafluoro cover and lower support tetrafluoro cover are fixedly connected on the two ends up and down of the round steel plug being coated with slicker solder layer respectively.Described upper support tetrafluoro cover and lower support tetrafluoro cover side are processed as four equally distributed arc-shaped protrusions, described upper support tetrafluoro cover upper and lower surface polishing is the first convex structure, and relatively outwardly, it is the second convex structure that described lower support tetrafluoro puts surface finish, and bottom is processed as cone-shaped structure.
Described upper support tetrafluoro cover and lower support tetrafluoro overlap concentric with oil pumping barrel steel pipe inner wall, and formation is slidably matched.
A kind of oil pumping barrel inwall piston-type chromium plating Special electric lead plating tin anode that the utility model provides, by electroplating lead tin alloy after the rust cleaning of round steel mandrel surface, alloying constituent is 8% tin and 92% lead, obtains one deck 1.5-2mm thick compactness slicker solder layer.Upper support tetrafluoro cover and lower support tetrafluoro cover, by being fixed on anode two ends after mechanical workout, because tetrafluoro cover has wear-resisting and precaution very well, can do the effect of support set; Lead plating tin anode guarantees the concentricity of anode and pump barrel caliber when the chromium plating of pump barrel inwall simultaneously, ensures the dimensional homogeneity of coating.
In use, due to long-time use, lead plating tin layers can progressively loss, when loss to a certain extent time, the surface treatment of slicker solder layer is totally electroplated onto specified dimension again, reuses.
This practicality lead plating tin anode is putting into practice about 5 times that work-ing life in use procedure is conventional anode.Thus greatly reduce production cost, also improve the quality of product simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is upper support tetrafluoro nested structure schematic diagram of the present utility model.
In figure: round steel plug 1, slicker solder layer 2, upper support tetrafluoro cover 3, lower support tetrafluoro cover the 4, first convex structure 5, second convex structure 6, cone-shaped structure 7, arc-shaped protrusions 8.
Embodiment
As in Fig. 1-2, a kind of oil pumping barrel inwall piston-type chromium plating Special electric lead plating tin anode, it comprises round steel plug 1, round steel plug 1 is electroplate with slicker solder layer 2, and upper support tetrafluoro cover 3 and lower support tetrafluoro cover 4 are fixedly connected on the two ends of the round steel plug 1 being coated with slicker solder layer 2.
The plating alloy composition that described lead plating tin layers 2 uses when electroplating is 8% tin and 92% lead.
As in Fig. 2, described upper support tetrafluoro cover 3 and lower support tetrafluoro overlap 4 sides and are processed as four equally distributed arc-shaped protrusions 8, reducing and oil pumping barrel steel pipe inner wall contact area, reducing friction when sliding.
As in Fig. 2, it is the first convex structure 5 that described upper support tetrafluoro overlaps 3 upper and lower surface polishings, and relatively outwardly, can not to the scratch of oil pumping barrel steel pipe inner wall when sliding up and down.
As in Fig. 2, it is the second convex structure 6 that described lower support tetrafluoro overlaps 4 upper surface polishings, and bottom is processed as cone-shaped structure 7.
Described upper support tetrafluoro cover 3 and lower support tetrafluoro cover 4 concentric with oil pumping barrel steel pipe inner wall, and formation is slidably matched.
Specific embodiment is as follows:
By electroplating lead tin alloy after round steel plug 1 surface derusting, alloying constituent is 8% tin and 92% lead, obtains one deck 1.5-2mm thick compactness slicker solder layer 2.Overlapping 3 upper and lower surface polishings by the upper support tetrafluoro after mechanical workout is the first convex structure 5, and it is the second convex structure 6 that lower support tetrafluoro overlaps 4 upper surface polishings, and bottom is processed as cone-shaped structure 7; Support tetrafluoro cover 3 and lower support tetrafluoro overlap 4 sides and are processed as four equally distributed arc-shaped protrusions 5.The sliding capability of anode at oil pumping barrel inwall can be improved by this structure; Upper lower support tetrafluoro cover is fixed on anode two ends, because this tetrafluoro cover has wear-resisting and precaution very well, can do the effect of support set; Lead plating tin anode guarantees the concentricity of anode and pump barrel caliber when the chromium plating of pump barrel inwall simultaneously, ensures the dimensional homogeneity of coating.
In use, due to long-time use, lead plating tin layers 2 can progressively loss, when loss to a certain extent time, slicker solder layer 2 surface treatment is totally electroplated onto specified dimension again, reuses.
