Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, specifically to a surface treatment device for metal pipe fittings. Background Technology

[0002] Surface treatment is a process that artificially forms a layer on the surface of a base material that has different mechanical, physical, and chemical properties from the base material. The purpose of this treatment is to meet the product's requirements for corrosion resistance, wear resistance, decoration, or other special functions. Metal pipe fittings intended for use in harsh environments require the application of anti-corrosion coatings before use to extend their service life.

[0003] For the surface treatment of metal pipe fittings, passivation is often used. Its main purpose is to form a stable, anti-oxidation and anti-corrosion protective film on the metal surface. After passivation, there will be passivation liquid on the surface of the metal pipe fittings. The residual chemical substances may react with the metal surface, causing or accelerating local corrosion and destroying the newly formed passivation film. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figures 1 to 8 This utility model discloses a surface treatment device for metal pipe fittings, comprising a hydraulic cylinder 1, a cleaning frame 2, and a passivation frame 10. A movable plate 8 is fixedly connected to the top of the piston rod of the hydraulic cylinder 1. A first servo motor 7 is fixedly connected to the upper surface of the movable plate 8. A support rod 6 is fixedly connected to the output end of the first servo motor 7. A connecting shaft 9 is fixedly connected to the lower surfaces of both ends of the support rod 6. A bottom rod 12 is fixedly connected to the bottom end of the connecting shaft 9. A limit assembly 13 is provided on the upper surface of the bottom rod 12. A pipe fitting body 11 is placed outside the limit assembly 13. A sliding plate 3 is slidably connected to the upper surface of the cleaning frame 2. A groove 302 is provided on the lower surface of the sliding plate 3. A spray head 14 is installed inside the groove 302. The cylinder 1 is powered by external conventional components such as oil pumps and oil tanks. The passivation frame 10 is filled with passivation fluid. The connecting shaft 9, the bottom rod 12, the limiting component 13 and other components are all made of corrosion-resistant materials. Under normal conditions, the sliding plate 3 is located at the edge of the cleaning frame 2 and will not affect the up and down movement of the moving plate 8 and the components above it. When cleaning is required, it is moved to the top of the metal pipe 11 by the second servo motor 15. At this time, the spray head 14 is located directly above the metal pipe 11. The connecting shaft 9 passes through the through groove in the center of one side of the sliding plate 3. The cleaning wastewater flowing out of the cleaning frame 2 needs to be collected and discharged only after the residue of passivation fluid in it has been treated.

[0028] The limiting assembly 13 includes a mating block 1301, a fixing ring 1302, a positioning shaft 1303, and a limiting shaft 1304. The mating block 1301 has a groove at its bottom, and the bottom rod 12 is fitted into the groove at the bottom of the mating block 1301. The bottom rod 12 and the mating block 1301 are fixedly connected by bolts and nuts. The positioning shaft 1303 is fixedly connected to the upper surface of the bottom rod 12. The mating block 1301 is slidably connected to the cylindrical surface of the positioning shaft 1303. The fixing ring 1302 is fixedly connected to the upper surface of the mating block 1301. The positioning shaft 1303 passes through the center of the fixing ring 1302. The limiting shaft 1304 is fixedly connected to the cylindrical surface of the fixing ring 1302. There are multiple limiting shafts 1304, which are evenly distributed about the axis of the positioning shaft 1303. The end of the limiting shaft 1304 away from the fixing ring 1302 is spherical, and the spherical surface of the limiting shaft 1304 is in contact with the inner cylindrical surface of the pipe body 11. The limiting assembly 13 has various specifications for the mating block 1301, fixing ring 1302, and limiting shaft 1304. The difference lies in the distance from the spherical edge of the limiting shaft 1304 to the center of the fixing ring 1302. This distance corresponds to the inner cylindrical radius of the various metal pipe fittings that need to be passivated. When passivating a certain specification of metal pipe fitting, the mating block 1301, fixing ring 1302, and limiting shaft 1304 of the corresponding specification are installed on the base rod 12. After the pipe fitting body 11 is installed, the inner cylindrical surface of the pipe fitting body 11 will contact the spherical surface of the limiting shaft 1304, thereby supporting the pipe fitting body 11 in the horizontal direction and preventing the pipe fitting body 11 from tipping over.

[0029] A water pump 4 is fixedly connected to the upper surface of the sliding plate 3. A diversion pipe 5 is fixedly connected to the output end of the water pump 4. The outlet end of the diversion pipe 5 passes through the sliding plate 3 and enters the spray head 14. The input end of the water pump 4 is connected to the water source through a hose.

[0030] A support plate 16 is fixedly connected to the side surface of the cleaning frame 2. A second servo motor 15 is fixedly connected to the upper surface of the support plate 16. A gear 17 is fixedly connected to the output end of the second servo motor 15. A through groove is provided at the top of the side wall where the support plate 16 is located on the cleaning frame 2. A toothed plate 301 is provided on the lower surface of the sliding plate 3. The toothed plate 301 passes through the through groove on the cleaning frame 2, and the toothed plate 301 meshes with the gear 17.

[0031] The passivation frame 10 and the bottom of the cleaning frame 2 are provided with outflow pipes, and control valves are provided on the outflow pipes. The sliding plate 3 is provided with a through groove at the center of the side near the cleaning frame 2, and the position of the connecting shaft 9 corresponds to the through groove of the cleaning frame 2.

[0032] Working principle: In use, the main body 11 of the pipe fitting is placed on the bottom rod 12 and fitted onto the outside of the limiting component 13. Then, the hydraulic cylinder 1 moves the main body 11 of the pipe fitting downward, immersing it in the passivation solution for passivation. During the passivation process, the main body 11 of the pipe fitting to be passivated is placed on the bottom rod 12 in the cleaning frame 2 area. After the passivation time is up, the hydraulic cylinder 1 removes the main body 11 of the pipe fitting from the passivation solution. Then, the first servo motor 7 rotates 180 degrees, positioning the passivated main body 11 above the cleaning frame 2. At this time, the unpassivated main body 11 is positioned above the passivation frame 10. Then, the hydraulic cylinder 1... Cylinder 1 causes the pipe body 11 to move down. At this time, the unpassivated pipe body 11 is immersed in the passivation liquid and passivated. The passivated pipe body 11 is located in the cleaning frame 2. Then, the second servo motor 15 drives the sliding plate 3 to move, so that the spray head 14 is above the passivated pipe body 11. Then, the spray head 14 sprays cleaning water to clean the passivation liquid remaining on the surface of the passivated pipe body 11. After cleaning, the second servo motor 15 drives the sliding plate 3 back to its original position and removes the cleaned pipe body. The new unpassivated pipe body is placed on the bottom rod 12 and waits for passivation.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
