Abstract
The invention discloses a process for spraying powder on a wheel hub. The process comprises the following steps of: 1) pre-treating the surface of the wheel hub and dehydrating and drying the surface; 2) spraying the powder on the entire surface of the wheel hub; 3) sucking away a powder layer on the part, which does not need powder spraying, on the surface of the wheel hub with a micro powder sucker; and 4) curing the powder. The powder layer on the part which does not need powder spraying is sucked away by the micro powder sucker, so that other parts are prevented from being influenced, and the situation of reworking due to the process is prevented. Thus, the process for spraying the powder is simplified, and the powder on the part, which does not need powder spraying, on the mounting surface of the wheel hub can be quickly, cleanly and accurately removed.
Description
Technical field
The present invention relates to a kind of powder injection process of wheel hub.
Background technology
Along with auto manufacturing enters environmental protection, energy-conservation and lightweight stage, aluminium and articles made of aluminium alloy have begun utilization in a large number on automobile.Aluminum alloy materials not only density is little, have suitable mechanical property and excellent characteristics such as corrosion resistance, weldability, mouldability and the surface of good property handled, and possess distinctive reproducibility, be the preferred material that automobile is realized loss of weight, energy-saving and environmental protection and safety.Advanced Sedan Car is used aluminum-alloy wheel now in a large number, according to the different requirements of product, adopts different processes.The existing main application development trend of global aluminium wheel hub is application wheel hub, bright wheel hub, polishing wheel hub and electroplates wheel hub etc.Have in the application wheel hub that two kinds of processing modes are a kind of to be powder injection process, another kind be lacquer spraying technique, and wherein powder injection process requires to adopt end powder to spray according to the difference of product and bright powder sprays.In the whole process of dusting, being handled easily and simplifying working process, all dusts in the surface of wheel hub.But the installed surface of wheel hub does not allow to dust, and in existing technology, is substantially before powder coating solidification, uses air gun that the powdery paints at the position that do not need to dust is blown clean.But do so easily near need the to dust powdery paints at position also together blow off, need dust again; Simultaneously also can cause the workspace powdery paints to fly upward, adhere to the installed surface that blows down but do not allow to dust again.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of process for spraying powder on wheel hub, can simplify powder injection process, with the wheel hub installed surface do not allow to dust local powdery paints fast, clean, accurately absorb; Simultaneously the workspace does not have powdery paints and flies upward, and can not cause powdery paints to adhere to again to have absorbed but the installed surface that do not allow to dust.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of process for spraying powder on wheel hub is characterized in that may further comprise the steps:
1) hub surface pre-treatment, dewatered drying then;
2) whole hub surface is dusted;
3) absorb hub surface do not need the to dust bisque at position with miniature starch absorbing device;
4) solidify.
As preferably, described hub surface dusts and adopt electrostatic spraying in powder spraying chamber.
As preferably, it is indoor that described miniature starch absorbing device is located at the suction powder that is independent of powder spraying chamber, and miniature starch absorbing device is inhaled the corresponding hub surface of powder rifle does not need the position of dusting.
As preferably, described wheel hub also will carry out electrostatic precipitation before dusting in the surface.
The present invention absorbs the anti-position that is coated with of needs owing to adopted the mode of miniature starch absorbing device, guarantee that other orientation are unaffected, has stopped therefore operation and the situation of doing over again again takes place.Thereby, simplified powder injection process, the powder that the wheel hub installed surface can not allowed the place of dusting is fast, totally, accurately remove.
The specific embodiment
Below for the embodiment of process for spraying powder on wheel hub of the present invention, may further comprise the steps:
1) hub surface pre-treatment, dewatered drying then;
2) whole hub surface is dusted;
3) absorb hub surface do not need the to dust bisque at position with miniature starch absorbing device;
4) solidify.
Wherein, conventional aluminium treatment process is adopted in the hub surface pre-treatment, and is special in the back of chromaking after washing, added the circulation pure water again and washed with fresh pure water and wash, and do not have any impurity to guarantee surface of the work, strengthens adhesive force of coatings.Before dusting, blow ionized air to wheel hub, remove because of the dust of Electrostatic Absorption on wheel hub with electrostatic precipitator.Dust and adopt electrostatic spraying in powder spraying chamber, workpiece begins rotation after arriving spray station, and coating sprays from oriented automatic spray gun, finishes spraying work.Powder spraying apparatus buying complete set of equipments has HV generator and coating retracting device.Described coating retracting device is a rotoclone collector, and the unnecessary powder that is scattered is drawn and reclaimed in its process of will dusting.It is indoor that described miniature starch absorbing device is located at independent suction powder, and starch absorbing device is inhaled the corresponding hub surface of powder rifle does not need the position of dusting.In powder spraying chamber, finish dust after, conveying device is delivered to wheel hub that to inhale powder indoor.
Claims (4)
1. process for spraying powder on wheel hub is characterized in that may further comprise the steps:
1) hub surface pre-treatment, dewatered drying then;
2) whole hub surface is dusted;
3) inhale the powder rifle with miniature starch absorbing device and absorb hub surface do not need the to dust powdery paints at position;
4) solidify.
2. process for spraying powder on wheel hub according to claim 1 is characterized in that: described hub surface dusts and adopt electrostatic spraying in powder spraying chamber.
3. process for spraying powder on wheel hub according to claim 2 is characterized in that: it is indoor that described miniature starch absorbing device is located at the suction powder that is independent of powder spraying chamber, and miniature starch absorbing device is inhaled the corresponding hub surface of powder rifle does not need the position of dusting.
4. according to claim 2 or 3 described process for spraying powder on wheel hub, it is characterized in that: described wheel hub also will carry out electrostatic precipitation before dusting in the surface.
