Abstract

The invention provides a shot blasting method for improving the surface coating performance and the appearance quality of an aluminum wheel of a vehicle. The method comprises the following steps of: burring after the aluminum wheel finishes heat treatment; selecting and placing 8 to 12 aluminum wheel blanks on a hanger of a shot-blasting machine; performing shot-blasting treatment by using 500 to 800 stainless steel shots; and obtaining the aluminum wheel of which the surface has uniform roughness, wherein 0.4 mm stainless steel shots account for 50 percent, 0.6mm stainless shots account for 50 percent, an injection pressure in a shot blasting process is of between 250 and 400 KPa, and the time is 3 to 5 minutes. By using the method, pin holes and slag blowholes on the surface of a product are reduced; the compactness of the surface of the product is improved; and an adhesive force is improved when performing post spray-painting and baking on the aluminum wheel so as to reduce the pin holes and the slag blowholes on the surface. Therefore, the method is of a surface treatment mode which is economic and practical and can improve the surface coating performance and the appearance quality.

Description

A kind of shot blasting method that promotes aluminum wheel of vehicle surface coating performance and presentation quality
Technical field
The present invention relates to a kind of automotive wheel surface treatment method, particularly a kind of shot blasting method that promotes aluminum wheel of vehicle surface coating performance and presentation quality belongs to the auto parts machinery field of surface treatment.
Background technology
Various wheels on the automobile are installed at present, for making its surface have good quality and aesthetic, the program of baking often needs to carry out to spray paint after machining is finished, for obtaining desirable surface treatment effect, aluminum wheel of vehicle manufacturing enterprise is often studied in pre-treatment and a lot of human and material resources of baking vanish link input, financial resources, though above method can obtain certain effect, but enterprise's input cost is big, production procedure is long, and therefore studying a kind of more economical suitable surface treatment method is questions of common interest in the industry.
Summary of the invention
The present invention seeks to overcome existing surface-treated technical deficiency, a kind of simple and easy to do, economic and practical aluminum wheel of vehicle surface treatment mode is provided, specifically be meant a kind of shot blasting method that promotes aluminum wheel of vehicle surface coating performance and presentation quality.
The technical scheme that realizes above method is: a kind of shot blasting method that promotes aluminum wheel of vehicle surface coating performance and presentation quality, promptly carrying out deburring after aluminum vehicle wheel is finished heat treatment process handles, then the aluminum vehicle wheel blank is placed on the hanger of shot-blasting machine, according to the disposable 8-12 spare aluminum vehicle wheel of on shot-blasting machine, placing of the volume of aluminum vehicle wheel, carry out Shot Blasting with the stainless shot of 500-800 kilogram, wherein the stainless shot of 0.4mm accounts for 50%, 0.6mm stainless shot account for 50%, expulsion pressure in the ball blast process is 250--400kpa, the ball blast time is 3-5 minute, and ball blast changes blank over to machined after finishing again, the routine processes of spraying paint.
Employing is with the desirable aluminum vehicle wheel that gets even surface roughness of upper type, make aluminum vehicle wheel when Hou Dao sprays paint baking, can improve the adhesive force on surface, the thickness of increase layer of paint, be not easy to cause the stream lacquer, improved the corrosion resistance of coat greatly, cinder hole, the pin hole on aluminum vehicle wheel surface have been reduced, make outward appearance better, so this method is a kind of economic and practical raising surface coating performance and the processing method of presentation quality.
From following technology of the present invention and traditional handicraft compare as can be seen, the more economical practicality of the present invention.
Use technology of the present invention and traditional handicraft contrast table
Project Traditional handicraft Technology of the present invention
Coating layer characteristic Test the depainting area about 4% with hundred lattice, powder thickness 100mm, adhesive force is relatively poor, and stream coats with lacquer easily in baking, and coating layer characteristic is general. Test the depainting area 2% with hundred lattice, powder thickness 120mm, adhesive force is better, is not easy the stream lacquer in baking, and coating layer characteristic is good.
Product appearance The not thick and easy stream lacquer of powder thickness manifests the little pin hole in aluminum vehicle wheel surface easily, and causes the back foaming of spraying paint, and influences presentation quality Contain crystallization water oxide behind the ball blast and be eliminated, the product surface compactness extent increases, and powder thickness increases, and significantly reduces aluminum vehicle wheel surface pinholes cinder hole, and presentation quality is good.
Spray paint and toast disposable qualification rate 70% 90%
The painting process cost 30-45 unit 20-30 unit

Embodiment 1
The 533-1770 aluminum vehicle wheel, carrying out deburring after wheel is finished heat treatment process handles, then the aluminum vehicle wheel blank is placed on the hanger of shot-blasting machine, on shot-blasting machine, place 12 according to the volume of aluminum vehicle wheel is disposable, carry out Shot Blasting with 500 kilograms of stainless shots, wherein the stainless shot of 0.4mm accounts for 50%, the stainless shot of 0.6mm accounts for 50%, and the expulsion pressure in the ball blast process is 300kpa, the ball blast time is 3 minutes, and ball blast changes blank over to machined, the routine processes of spraying paint after finishing again.
Embodiment 2
The 638-2295 aluminum vehicle wheel, carrying out deburring after wheel is finished heat treatment process handles, then the aluminum vehicle wheel blank is placed on the hanger of shot-blasting machine, according to placing 8 aluminum vehicle wheels on the disposable shot-blasting machine of the volume of aluminum vehicle wheel, carry out Shot Blasting with 800 kilograms of stainless shots, wherein the stainless shot of 0.4mm accounts for 50%, the stainless shot of 0.6mm accounts for 50%, and the expulsion pressure in the ball blast process is 400kpa, the ball blast time is 5 clocks, and ball blast changes blank over to machined, the routine processes of spraying paint after finishing again.
