Abstract
The invention discloses a kind of aluminium alloy wheel hub of vehicle surface frosted coating process, it is characterised in that including following processing steps: successively after casting, heat treatment, machining, deburring, then successively carrying out ball blast processing, pre-treatment, spray painting, drying.The invented technology is reasonable, and finished surface is smooth, and coating quality is good, and accepted product percentage is high.
Description
Technical field
The present invention relates to automotive field, specifically a kind of aluminium alloy wheel hub of vehicle surface frosted coating process.
Background technique
When manufacturing aluminium alloy wheel hub of vehicle, for beauty, the appearance by its external coating at different-effect is needed sometimes, is ground
Sand is exactly using a kind of more appearance, and in order to reach this frosted finish effect, the method used now is: first successively being carried out
Casting, heat treatment and ball blast processing after, then be successively machined, deburring, pre-treatment, spray painting and drying, use it is this
1 is had the following disadvantages: when process, due to the workpiece after cast and heat treatment, surface has such as bump injury, contracting
The defects of coating on pine, oxide skin and casting mould causes workpiece surface rough and uneven in surface need to be into order to eliminate these defects
Row a large amount of manual polishing processing, still it is difficult to ensure that the consistency of workpiece surface, and these defects after Shot Blasting still
It can not so eliminate, bad so as to cause product appearance, rejection rate is very high；2, since the technique is machined after first ball blast, this
Sample will be such that the frosted finish effect generated after Shot Blasting on workpiece surface is turned on, can only retain on workpiece surface without
The frosted finish effect of turnery processing part causes the overall appearance effect of workpiece poor；3, the appearance workpiece defective after coating
It cannot be reprocessed by the method for polishing, because when reprocessing the frosted finish effect on workpiece surface can be destroyed, and reprocessing
When, it is reprocessed in the color and workpiece of the workpiece surface of part that there are color difference without the color of reprocessing part, easily leads to waste product.
Summary of the invention
It is an object of the invention to provide a kind of rational technology, finished surface is smooth, coating quality is good, accepted product percentage is high
Aluminium alloy wheel hub of vehicle surface frosted coating process.
A kind of aluminium alloy wheel hub of vehicle surface frosted coating process of the present invention, it is characterised in that including following processing steps:
A. it casts: workpiece being gone out using hot-cast die casting on casting machine；
B. it is heat-treated: solution treatment first being carried out to workpiece in roll-type continuous heat treating furnace, furnace temperature is between 535 ± 5 DEG C, solid solution
Handling the time is 300 minutes, then, workpiece is taken out from furnace, and be passed in quenching tank and be quenched, quenching tank
Water temperature is between 60~80 DEG C, and the cool time is 2 minutes, and after the completion of quenching, it is right into roll-type continuous heat treating furnace that workpiece is sent
It carries out artificial aging processing, allows its natural cooling after keeping the temperature 150 minutes in the furnace temperature between 135 ± 5 DEG C；
C. it is machined: turnery processing being carried out to workpiece on numerically controlled lathe, remove the part of workpiece surface existing defects；
D. deburring: the burr part by manually removing workpiece；
E. ball blast is processed: carrying out ball blast processing to workpiece surface using graininess quartz sand on shot-blasting machine；
F. pre-treatment: carrying out continuous productive process processing according to following order: first being cleaned in the aqueous solution of PH7-PH14, then,
Pre- degreasing is carried out in the buck that total alkali point is 5-10, then carries out main degreasing in the buck that total alkali point is 5~10, is then existed
Washing one is carried out in the aqueous solution of PH7~PH8, then, washing two is carried out in the aqueous solution of PH5.5~PH7.2, then free
Acid o'clock carries out pickling in 5~10 sour water, and washing three is then carried out in the aqueous solution of PH4~PH7, then, PH4~
Washing four is carried out in the aqueous solution of PH7, then place is passivated in 0.2~1.2 passivating solution in PH3.6~PH4.2, total acid o'clock
Reason, washing five is then carried out in the aqueous solution of PH7, then, washing six is carried out in the aqueous solution of PH7, finally, being in temperature
It is toasted 30 minutes in 140 DEG C of drying oven；
G. it paints: with spray gun for paint in workpiece surface spraying finishing coat；
H. it dries: being toasted 40 minutes in the drying oven that temperature is 180 ± 5 DEG C.
The present invention is due to using the method for first passing through and carrying out ball blast processing after machining, deburring, in this way, passing through machine
Tool processing after deburring, can remove the bad part of workpiece surface, it can be ensured that workpiece surface is smooth, and can effectively ensure that through
After ball blast processing, make the overall appearance of workpiece that there is good frosted finish effect.Present invention process is reasonable, and finished surface is smooth, applies
Packing quality is good, and accepted product percentage is high.
