Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, in particular to a nano solid lubricating dry film spraying device for automobile wear-resistant parts. Background Art

[0002] Solid lubricants are materials that use solid powders, films or certain integral materials to reduce the friction and wear between two load-bearing surfaces. During the solid lubrication process, the solid lubricant and the surrounding medium will undergo physical and chemical reactions with the friction surface to form a solid lubricant film to reduce friction and wear. Solid lubricants usually have good surface adhesion, low shear strength, good stability and high load-bearing capacity, and are therefore widely used in the wear-resistant treatment of automotive parts such as gears, bearings and rotating pipes.

[0003] In terms of application methods, solid lubricating materials such as glass fiber, metal fiber, graphite fiber, etc. can be made into integral parts and are mostly used in the manufacture of small wear-resistant parts such as gears, bearings, guide rails, cams, etc.; for larger pipe parts or shaft parts, physical methods are often used to apply solid lubricants to the friction interface or surface to make it a dry film with certain self-lubricating properties. The specific film-forming methods include sputtering, electrophoresis, spraying, dipping, roller coating, etc.; in addition, solid lubricating materials are often ground into solid powder and added to lubricating oil or grease.

[0004] However, due to the particularity of the workpiece shape and spraying position and the limitations of the spraying equipment function, a series of problems often arise when spraying and film-forming nano solid lubricant materials on the surface of automotive wear-resistant pipes, including:

[0005] 1. The processing continuity is poor and the degree of automation is low, making it difficult to realize automatic loading and unloading before and after processing.

[0006] 2. The adaptability of clamping is poor, and it is difficult to clamp different types of wear-resistant pipes. Improper selection of clamping position can easily block the spraying position and affect the spraying effect. After clamping, it is inconvenient to switch between different positions, resulting in the inability to fully cover the spraying range.

[0007] 3. The spraying mechanism has poor adjustability, which may cause uneven spraying and dead corners.

[0008] 4. The overall sealing of the equipment is poor, and it is inconvenient to adjust various parameters.

[0009] 5. Real-time drying is inconvenient, which affects processing efficiency.

[0010] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
