Embodiment 1

[0021] A coating method for a wheel hub, the specific steps comprising:

[0022] ① Pre-treatment: Wash the metal shavings and dust on the surface of the hub with hot water at 60-85°C in the washing tank, remove the grease and oxide film on the surface of the hub with a cleaning agent, wash it with clean water several times, and then dry it;

[0023] ② Electrophoresis: Prepare the electrophoretic paint, mix the electrophoretic paint evenly, load the hub on the electrophoretic rack, immerse the spokes under the liquid surface of the electrophoretic paint, and keep the bolt holes and center holes outside the electrophoretic paint;

[0024] ③Cleaning: Wash the wheels after electrophoresis with ultrafiltration water to wash off the electrophoretic paint adhered to the surface of the wheels;

[0025] ④Spray the primer: Use a small-caliber spray gun to spray the primer twice, the interval between the two times is 10-20min, control the first spraying pressure to 0.20-0.30MPa, control ...

Abstract

The invention provides a coating method of a wheel hub, and relates to the technical field of automobile products. The coating method comprises the following steps of pre-treatment; electrophoresis; cleaning; priming paint spraying; primary drying; paint spraying; secondary drying; and polished finish. Priming paint is sprayed twice by adopting a small-caliber spray gun, the interval time twice is10-20 min, the spraying pressure for the first time is controlled to be 0. 20-0.30MPa, the second spraying pressure is controlled to be 0.25-0.35MPa, the spraying distance is 5-10cm, the angle is selected according to the shape of the product, and after spraying is completed, the wheel hub is stood for 15-18min; The wheel hub is subjected to infrared drying at 70 DEG C for 11-15 minutes; electrostatic powder spraying is adopted, and the powder coating is uniformly sprayed on the surface of the wheel hub; and the sprayed wheel hub is solidified and dried, the drying temperature is 200-220 DEGC, and the solidified and dried wheel hub is naturally cooled at normal temperature. According to the coating method, the adhesive force of the coating and the wheel hub is enhanced, the cost is saved, the product strength is high, the toughness is good, the wheel hub quality is good, the machining precision is high, the deformation and the impact resistance is high, and the popularization of a product is facilitated.

Description

technical field [0001] The invention relates to the technical field of automotive supplies, in particular to a coating method for a wheel hub. Background technique [0002] With the development of the motor vehicle industry, the output and stock of motor vehicles have increased, driving economic development and bringing convenience to people's travel. [0003] The wheel hub is an essential part of the car, and its performance is directly related to the smooth running and safety performance of the vehicle. However, the hubs of some wheels currently have the problem of weak impact resistance. [0004] Painting is the last process in the production of automobile wheels, and its purpose is to improve the corrosion resistance and aesthetic feeling of automobile wheels. At present, in the coating of automobile wheel hubs, the coating method is often more complicated, the steps are cumbersome, and it consumes a lot of manpower and material resources.
