Step 3, cleaning-drying, first carries out the process of second time hot water wash to wheel hub blank, then dries;
Step 4, chromium-free deactivation process, carries out chromium-free deactivation process by scavenging solution to hub surface in washing bath;
Step 5, spraying end powder and solidification;
Step 6, mechanical process, carries out mechanical process to wheel hub, polishes, make hub surface smooth to the wheel hub after spraying end powder;
Step 7, second time is sprayed paint process, again heats wheel hub at pretreatment line, and wheel hub is proceeded to painting line spray paint from processing line, has sprayed paint to be cured process successively to wheel hub afterwards;
Step 8, vacuum plating, by the wheel hub through above-mentioned process in vacuum chamber according to vacuum sputtering coating principle metallize coating;
Step 9, spraying Clear coating, spraying polyurethane propenoic acid ester photocureable sizing agent on the wheel hub after above-mentioned vacuum plating, increases the glossiness of wheel hub.
On the basis of technique scheme, the present invention can also do following improvement.
Further, in described step one, described first time hot water wash processing mode for adopting water pistol, automotive hub is sprayed, the temperature of water is 55-70 DEG C, sprays 0.1-0.3MPa, and spray time is 2.0-3.5min.
Further, in described step 2, oil removal treatment mode is that the scavenging solution adopting water, concentrated type clean-out system and tensio-active agent to mix successively sprays.
Further, in described step 5, powder and solidification at the bottom of described spraying comprise employing electrostatic spraying spraying epoxy polyester powder coating, then solidify 15 minutes at 200 DEG C of temperature.
Further, in described step 7, in described painting process, rifle is apart from 100-200mm, and the time of dusting is 30s, thicknesses of layers front >=50 μm, window >=50 μm, and the raw material that dusts is mute black powder.
Further, after described step 9 also through check processing: to wheel hub carry out successively paint film property detection, outward appearance detect and transient equilibrium detect.
The invention has the beneficial effects as follows: wheel hub application of the present invention is dusted lacquer spraying technique, wheel hub performance can be improved, technique is simple, painting effect is good, by blasting medium powder and solidification, increase the planeness of hub surface, glossiness, hardness, erosion resistance and closed hub surface, improve the bonding force of vacuum-coating; Clear coating, the sticking power of high vacuum coating, increases the glossiness of wheel hub, hardness, wear resistance and corrosion resistance; Concise in technology of the present invention, energy consumption is low, and the hardness of the wheel hub of making is high, erosion resistance is strong.
