Leading the new trend of spraying technology, spring electrostatic automatic spraying machine
The necessity of spring spraying is mainly reflected in the following aspects:
1. Anti corrosion protection: When the spring works in various environments, its surface is easily corroded. Spraying can form a protective layer to prevent the spring from being damaged due to corrosion and extend its service life.
2. * * Improve fatigue life * *: Through shot peening and other methods, many small pressure pits can be generated on the surface of the spring to form a work hardening layer, thereby improving the fatigue life of the spring.
3. * * Improving appearance * *: Electroplating and other spraying methods can not only protect the spring, but also improve its appearance, making the surface of the spring smoother and brighter, and enhancing the overall beauty of the product.
4. * * Improve working performance * *: Electroplating layers of certain metals can enhance the surface hardness, wear resistance, and thermal stability of springs, thereby improving their working performance.
5. * * Adapt to special environments * *: In specific working environments, such as oceanic or high-temperature atmospheres, certain springs require special spray coatings (such as cadmium plating) to improve their corrosion resistance.
6. * * Preventing hydrogen embrittlement * *: During the electroplating process, hydrogen may penetrate into the spring material, causing internal stress and making the spring brittle. By dehydrogenation treatment, these defects can be eliminated and the physical and chemical properties of the spring can be improved.
7. * * Improve production efficiency * *: The use of automated spraying equipment can improve production efficiency, reduce labor costs, and ensure the uniformity and quality of spraying.
8. Environmental considerations: Some spraying methods, such as electrostatic spraying, can reduce solvent evaporation, minimize environmental impact, and protect workers' health.
In summary, spring spraying is an important process step for improving spring performance, extending service life, and adapting to diverse working environments.
