The disclosure provides an anti-aging periodic variable reaction black chromium coating film, sequentially comprising: an aluminum alloy matrix, a silane conversion film, a high-gloss organic resin coating, a metal compound and metal element periodic variable content alloy coating film, and a transparent resin coating. The disclosure simultaneously provides a method for forming the anti-aging periodic variable reaction black chromium coating film.

Anti-aging periodic variable reaction black chromium coating film and forming method thereof

The invention discloses an automatic powder cleaning system for mixed-line hub bolt holes and a combined powder cleaning gun. The powder cleaning system comprises a control system, a recognition system, a powder cleaning robot, a gun storage and an accessory device. A plurality of combined powder spraying guns are arranged in the gun storage, and a quick disassembly fixture is arranged at the end of the powder cleaning robot. The powder cleaning system adopts robot programming and hub recognition technologies; according to the sizes of different hub bolt holes, ball sockets and platforms as well as product standards, the robot automatically and quickly selects different types of combined powder cleaning guns; after powder spraying under the condition that the hub is not provided with protectors, the head of the central gun barrel absorbs powder at the bolt hole, and the ball socket and platform gun barrel absorbs powder at the ball socket and platform of the bolt hole; protective small plugs for bolt holes are replaced by the powder cleaning gun, so that a large number of small plugs are avoided, the production cost is reduced, and the environmental pollution caused by paint drop of the small plugs is prevented; and the absorbed powder can be reused, so that the automatic powder cleaning system and the combined powder cleaning gun conform to the green, lean and automatic development process of modern enterprises.
