[source] aluminum alloy wheel hub

Aluminum alloy products because of the many advantages of material, is more and more used in industrial manufacturing. Aluminum alloy wheel hub for light weight saving energy, high precision and tire separation, reduce vibration and vibration, improve the body center, easy machining, good balance, good heat dissipation, beautiful and other visible advantages, and many car manufacturersare used.

However, in the rapid development of the domestic auto industry and the global division of fine today, more and more car manufacturers will be partssubcontracting to different suppliers (automobile manufacturing division, see "a map read: robot cars": http:// www.think-automation.com/shownews.asp? Id=21 shown in the parts Crowdsourcing). Because of the market for consumer demandand to improve the quality of the picky, car manufacturers for parts quality andsubcontractor foundry more demanding, so, an aluminum alloy wheels, starting from the initial casting / forging billet shape, to the final delivery to undergo a number of links, do not know how much labor hands operation:

At the same time -- if you really went to China these sweatshops workshop, youknow how bad working environment, to ink a peasant perception, theenvironment than facing loess back upturned agricultural production environment.

[aluminum alloy wheel manufacturing process analysis and robot application]

(1) the blank is made: the gravity casting, low pressure casting, pressure casting,extrusion casting or forging, semisolid die forging process into the hub model.(note, aluminum alloy wheel hub by magnesium alloy, limit, due to the length ofthis paper does not illustrate) blank manufacturing should be carried out after theX ray flaw detection, eliminate unqualified products.

* robot applications: handling, processing, sand mould casting poured the soup,die casting pickup, detection of casting process.

(2) heat treatment: casting wheel blank completed was last 6~7 hours at 528~535 ℃ solution furnace; and then remove the 20S time, must be immersed in 70 degrees Celsius and quenching in aqueous solution; and then continued for 5hours heating at 255~170 deg.c; finally, check the tensile strength, elongation,hardness to determine the effect of heat treatment and microstructure, eliminateunqualified products.

* robot applications: intermediate link equipment line, handling transfer.

(3) machining: because hub complex shape (should the needs of the market, all kinds of flowers), need to be divided into 4 process steps: turning, decorativehole 钻镗 processing positive, drilling and milling valve core hole, the back of theturning processing. Usually, according to the model machine equipment performance is different, the process need to be completed on the 1~4 machineroom. Then eliminate unqualified products.

* robot applications: the machine loading and unloading, detection and handling.

(4): polished aluminum alloy wheel machine finished just a hub of appearance,but the cutting surface and edge machine finished part needs to be polished to remove the burr and burr, burr increased edge bluntness, finally polished (it isoperational aspects of the malignant accident in). The above process is completed, the need for size check with feeler gauge, (note, here the detection accuracy at the government level 0.05mm.) , and air tightness and balance test.Weed out unqualified products.

* robot applications: grinding, flying edge, burr, high pressure cleaning, polishing,detection and handling.

(5) spraying: spraying is a more complicated process, requiring 6 process:

The pretreatment process of A.9: 2 oil removal (waxing machine processing oflubricating oil, when polishing), 1 road, 1 road, 1 flush degreasing syringing,chrome, 2 ion to sleep wash;

B. at 120, 15 minutes of drying;

C. electrostatic powder spraying 60 μ m

D. at 220 ℃, 25 minutes of curing;

E. spraying liquid lacquer;

F. at 220 ℃, 25 minutes of curing.

After removing substandard goods.

* robot applications: electroplating handling prepreg, electrostatic powder spraying, intermediate link connection handling, high pressure cleaning, painting.

(6) inspection and packaging:

A. performance test: size, salt spray test, weathering, macadam, film thicknesstest, cross cut, mechanical properties, impact test, bending fatigue test, radialfatigue test;

B. surface detection: detecting whether the surface quality meets the car factoryto customer requirements, various accessories are ready;

C. on the packaging of products, goods delivery.

* robot applications: detection of handling, surface inspection, handling charge basket packing, palletizing.
