Abstract
The invention discloses an automobile half-shaft phosphorization process. According to the technical scheme adopted by the automobile half-shaft phosphorization process, the automobile half-shaft phosphorization process is characterized in that the phosphorization treatment is carried out on an automobile half-shaft in order to completely clear away and find oxide scales, oil stains, concealed cracks and residual impurities in the quenched automobile half-shaft, and the surface of the half-shaft is black, and the automobile half-shaft phosphorization process comprises the following phosphorization technological processes: carrying out degreasing pretreatment, degreasing, cleaning with hot water, washing with cold water, carrying out ultrasonic wave rust removal, cleaning with warm water, carrying out activating treatment, phosphating, washing with water, carrying out ultrasonic wave rinsing, cleaning with a chemical agent and drying.
Description
Technical field
The present invention relates to phosphating process, be specifically related to a kind of automobile axle shaft phosphating process.
Background technology
Automobile axle shaft is the direct actuator of vehicle wheel rotation, is a strength member of transmitting torque.During automobilism, engine output torque, passes to semiaxis through multi-speed change and actuator, then is passed on wheel by semiaxis, and propelling vehicle advances or backward.When starting or go up a slope, moment of torsion is very large, and especially in snub or travel on uneven road, working conditions is more severe.Therefore semiaxis withstands shocks when work, and the effect of alternating bending fatigue loading and moment of torsion, requires material to have enough bending strengths, slip resistance and preferably toughness.Automobile axle shaft not only requires high in inner quality, and the pursuit of Surface Quality is more and more higher, and wherein phosphating process plays an important role in semiaxis surface treatment, has caused automaker's great attention.Phosphatization is progressively applied in automobile axle shaft production technique as an important industrial technology, has improved surface quality and the surface gloss of automobile axle shaft, is subject to user and likes after tentatively putting on market.
Summary of the invention
The invention provides a kind of automobile axle shaft phosphating process, utilize automobile axle shaft phosphating process of the present invention to manufacture automobile axle shaft, not only improved surface quality and the surface gloss of automobile axle shaft, and the phosphatize phosphate coat on surface rust protection and corrosion-resisting function have been played.
The technical scheme that automobile axle shaft phosphating process of the present invention adopts is: in order thoroughly to remove and find oxide skin, greasy dirt and hiding crackle and residual impurity in the automobile axle shaft after quenching, automobile axle shaft is carried out to bonderizing, semiaxis surface color is black, and its phosphating process flow process is: degreasing pre-treatment, and------------ultrasonic cleaning---------------phosphatization is dried activation treatment in washing in warm water cleaning by ultrasonic rinsing---chemical agent cleaning---in cold water cleaning in hot water cleaning in degreasing.
Concrete phosphating process is:
1. degreasing pre-treatment
With 7%～10% scavenging solution, be watered and be heated to 40 ℃～50 ℃, semiaxis is placed in Ultrasonic Cleaners, vibration washing takes out for 12～15 minutes.
2. degreasing
With 5%～10% grease-removing agent, be watered and be heated to after 60 ℃～80 ℃, automobile axle shaft is placed in degreasing pond and is soaked or the cleaning 10～15 minutes of rolling.
3. hot water cleans
With soft clear water, be heated to 70 ℃～90 ℃, semiaxis is placed in pond and is cleaned 8～10 minutes.
4. cold water cleans
Use normal temperature tap water, semiaxis is placed in cold water service sink and is cleaned 5～8 minutes.
5. ultrasonic cleaning
With 12%～15% phosphoric acid, be watered, semiaxis is placed in Ultrasonic Cleaners to vibration washing 3～5 minutes.
6. warm water cleans
With soft tap water heating to 40 ℃～50 ℃, semiaxis is placed in pond and is cleaned.
7. activation treatment
Semiaxis is placed in the solution of the phosphoric acid titanium salt that contains colloidal state and soaks 10～15 minutes.
8. phosphatization
With black phosphating solution 12%～15%, be watered heating and temperature control between 75 ℃～80 ℃, semiaxis is placed in phosphating pond to 20～25 minutes, phosphatize phosphate coat is controlled between 0.003～0.005mm and is advisable.
9. washing
With clean clear water, semiaxis is cleaned up.
10. ultrasonic rinsing
The mode that adopts ultrasonic vibration to clean, removes clean by being penetrated into its crack and intrapore debris and magazine in degreasing, rust cleaning, activation, parkerizing process.
11. chemical agents clean
With 2%～3% cleaning machine, converting clean clear water cleans.
12. dry
Employing dries up or dries all can.
Beneficial effect of the present invention is: semiaxis surface quality is good, has attractive in appearance and corrosion-resisting function.
