Description
Technical field:
The present invention relates to automotive hub processing and manufacturing technologies, and in particular to a kind of simple blowing of automotive hub is set
It is standby.
Background technology:
Wheel hub is wide support the drum-shaped of tire, metal parts of the center on axis in tire.It is called wheel rim, steel
Circle, wheel, tire bell.Wheel hub is various according to diameter, width, molding mode, material variety classes.
Wheel hub is called wheel rim.According to the feature and demand of different automobile types, hub surface treatment process can also be taken different
Mode is broadly divided into two kinds of baking vanish and plating.The wheel hub of ordinary vehicle type considers less that thermal diffusivity is one well in appearance
Basic demand, substantially using paint baking in technique, i.e. first spraying and then electricity is roasting, and cost is both economical and color is beautiful, protects
Hold that the time is permanent, even if vehicle scrapping, the color of wheel hub is still constant.Much masses' vehicle hub surface treatment process are all
Baking vanish.What fashionable, the full of moving sense colored wheel hub of some fashion used is also baking vanish technology.This kind of wheel hub is moderate, specification
It is complete.Plating wheel hub is divided into the types such as electrosilvering, water power plating and pure plating.Although electrosilvering and water power plating wheel hub bright life
It is dynamic, but the retention time is shorter, so price is relatively cheap, is liked much to pursue fraicheur young man, the market price
Between 300 yuan -500 yuan.Pure plating wheel hub, the color and luster retention time is permanent, can say it is that valency of fine quality is high.Medium-to-high grade car multiselect is used
Pure plating wheel hub, about 800-900 yuan of price.
Manufacture:There are three types of the manufacturing methods of aluminium alloy wheel hub:Gravitational casting, forging, low pressure hot investment casting.1. gravity
Casting is poured into aluminium alloy solution in mold using gravity, handles and polishes through lathe after shaping, you can completes production.Manufacture
Process is simpler, is not required to accurate casting technique, at low cost and production efficiency is high, but easily generation bubble (sand holes), density
Uneven, surface smoothness is inadequate.It is lucky have a suitable vehicle adapted be exactly the production of this method wheel hub, it is mainly early
The vehicle of phase production, new model have used trendy wheel hub instead more.2. forging method monoblock aluminium ingot is by the forcing press of kiloton on mold
Direct extrusion forming, benefit are even densities, and smooth surface is careful, and wheel hub wall is thin and light-weight, strength of materials highest, than casting
More than method is three one-tenth high, but due to needing more superior production equipment, and yield rate only has five to sixty percent, manufacture cost compared with
It is high.3. the hot investment casting under the low pressure of 0.1Mpa of low pressure microcast process, the formability of this forging type is good, clear-cut,
Even density, any surface finish can reach high intensity, lightweight and control cost, and yield rate is more than ninety percent
The mainstream manufacturing method of high-quality aluminum alloy wheel hub.
And wheel hub typically manual operation when blowing cleaning, cooling, so easily wheel hub is caused to damage, and
And it needs manually ceaselessly to stir when cleaning, unusual waste of manpower.
The content of the invention:
The technical problems to be solved by the invention are existing technological deficiency is overcome to provide a kind of rational in infrastructure, operation side
Just a kind of, the simple blowing apparatus of blowing easily automotive hub.
The technical problems to be solved by the invention are realized using following technical solution:
A kind of simple blowing apparatus of automotive hub, it is characterised in that:Including supporting rack, bottom is provided with above supporting rack
