TECHNICAL FIELD
[0001] The utility model relates to spring steel wire production field, concretely is a spring steel wire phosphorization treatment production line. BACKGROUND
[0002] Spring is a common mechanical component, and is widely used in automobile, aerospace, mechanical manufacturing and many other fields. It can store energy by its elastic deformation and plays a key role in buffering, shock absorption and resetting in various devices. It is an indispensable component to ensure the normal operation of many mechanical devices. Steel wire is the main raw material for producing spring, and its quality directly determines the performance of spring.
[0003] Before the steel wire is made into spring, phosphating treatment is a crucial process. Phosphating treatment can form a dense phosphating film with certain protective properties on the surface of the steel wire. This film can significantly enhance the corrosion resistance of the steel wire, preventing rusting during subsequent processing, storage and use due to contact with humid air and corrosive media, thereby ensuring the service life of the spring. During phosphating of the steel wire, the steel wire needs to be immersed in a phosphating solution with a specific formula. Under suitable temperature, time and other process conditions, the phosphate ions in the phosphating solution interact with the iron atoms on the surface of the steel wire through chemical reaction, gradually depositing to form a phosphating film.
[0004] Due to the long-term placement of the steel wire in the factory building, rust appears on the surface of the steel wire. The oxides on the surface of the steel wire hinder the chemical reaction between the phosphate ions in the phosphating solution and the metal, resulting in uneven phosphating film attached to the surface of the steel wire.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] The embodiments of this utility model will be described below based on its overall structure.
[0033] A phosphate treatment production line for spring steel wire, such as Figure 1 - Figure 5 As shown, the device includes a cleaning device 1, with an inlet 101 on one side. Two sets of support rollers 2 are installed at the end of the inlet 101. A first motor 3 is installed inside the cleaning device 1, and a rotating rod 301 is fixed to the end of the first motor 3. A first grinding roller 302 and a second grinding roller 303 are installed on the outer wall of the rotating rod 301. A cleaning ring 4 is installed inside the cleaning device 1, with a pipe opening 102 at the end of the cleaning ring 4. A cleaning ring 5 is installed on one side of the cleaning ring 4. This solution addresses the severe oxide buildup on the surface of the steel wire. Technical issues affecting the effect of steel wire in the phosphate process: When the steel wire moves at the top of the support roller 2, it first contacts the first grinding roller 302. The abrasive particles on the surface of the first grinding roller 302 are relatively rough. The first grinding roller 302 performs preliminary grinding and removal of rust on the surface of the steel wire. Then the steel wire moves to the bottom of the second grinding roller 303. The abrasive particles on the surface of the second grinding roller 303 are relatively fine. The second grinding roller 303 grinds the burrs and rust on the surface of the steel wire, making the surface of the steel wire smoother and flatter.
[0034] Please see Figure 2The distance between the first grinding roller 302 and the two sets of support rollers 2 is equal to the diameter of the steel wire. During the movement of the steel wire on the support rollers 2, the outer wall of the steel wire can contact the first grinding roller 302. The steel wire moves between the two sets of support rollers 2. The support rollers 2 support the steel wire so that the steel wire will not shift its position when the first grinding roller 302 grinds the steel wire.
[0035] Please see Figure 2 The abrasive particles attached to the surface of the first grinding roller 302 are large, while the abrasive particles attached to the surface of the second grinding roller 303 are small. The abrasive particles on the surface of the first grinding roller 302 are relatively rough, and the first grinding roller 302 performs preliminary grinding and removal of rust on the surface of the steel wire. Then, the abrasive particles on the surface of the second grinding roller 303 are relatively fine, and the second grinding roller 303 grinds the burrs and rust on the surface of the steel wire, making the surface of the steel wire smoother and flatter, which is conducive to the subsequent phosphating reaction of the steel wire.
[0036] Please see Figure 3 A cleaning sleeve 401 is installed on the inner wall of the cleaning ring 4. A water inlet pipe 402 is provided on one side of the cleaning device 1, and the end of the water inlet pipe 402 is connected to the inside of the cleaning ring 4. The cleaning liquid enters the cleaning ring 4 through the water inlet pipe 402, and the cleaning liquid entering the cleaning ring 4 wets the surface of the steel wire through the cleaning sleeve 401.
[0037] Please see Figure 4 A first gear 502 is fixed to the outer wall of the cleaning ring 5. A second gear 503 is connected to one side of the first gear 502. A second motor 504 is installed at one end of the second gear 503. The second motor 504 drives the second gear 503 to rotate.

[0038] Please see Figure 4 The inner wall of the cleaning ring 5 is equipped with a brush 501, and the brush 501 has a certain elasticity. The rotating cleaning ring 5 cleans the dust and iron filings on the surface of the steel wire through the brush 501 on the inner wall, so that no impurities are attached to the surface of the steel wire.
[0039] Please see Figure 5 The cleaning device 1 is equipped with a third motor 601. A fan 6 is fixed to one end of the third motor 601. When the steel wire is conveyed to the cleaning ring 5, the third motor 601 drives the fan 6 to rotate at high speed. The air generated by the rotation of the fan 6 dries the surface of the steel wire.
[0040] Please see Figure 5The inner wall of the cleaning device 1 is provided with a water collection tank 7, and a drain pipe 701 is installed at the end of the water collection tank 7. During the drying process of the steel wire by the blower 6, the liquid on the surface of the steel wire drips into the water collection tank 7, and the water collection tank 7 guides the liquid to the drain pipe 701 for discharge.
[0041] The working principle of this utility model is as follows: First, the steel wire is conveyed into the cleaning device 1 through the inlet 101. The first motor 3 drives the first grinding roller 302 and the second grinding roller 303 to rotate synchronously through the rotating rod 301. When the steel wire moves at the top of the support roller 2, the steel wire first contacts the first grinding roller 302. The abrasive particles on the surface of the first grinding roller 302 are relatively rough, and the first grinding roller 302 performs preliminary grinding and removal of rust on the surface of the steel wire. Then, the steel wire moves to the bottom of the second grinding roller 303. The abrasive particles on the surface of the second grinding roller 303 are relatively fine, and the second grinding roller 303 grinds the burrs and rust on the surface of the steel wire, making the surface of the steel wire smoother and flatter. Then, the steel wire that has completed the grinding process enters the cleaning ring 4 through the pipe 102, and the cleaning fluid passes through... The water inlet pipe 402 enters the cleaning ring 4. The cleaning fluid in the cleaning ring 4 wets the surface of the steel wire through the cleaning sleeve 401. Then the steel wire is conveyed to the cleaning ring 5. The second motor 504 drives the second gear 503 to rotate. The second gear 503 drives the cleaning ring 5 to rotate through the first gear 502. The rotating cleaning ring 5 cleans the dust and iron filings on the surface of the steel wire through the brush 501 on the inner wall, so that no impurities are attached to the surface of the steel wire. After the steel wire is conveyed to the cleaning ring 5, the third motor 601 drives the fan 6 to rotate at high speed. The air generated by the fan 6 dries the surface of the steel wire. During the drying process of the fan 6, the liquid on the surface of the steel wire drips into the water collection tank 7. The water collection tank 7 drains the liquid into the drain pipe 701 for discharge.
