山东铝合金压铸件表面的抛丸清理方法:对铝合金压铸件进行抛丸清理后,可达到如下效果。
Shot blasting cleaning method of Shandong Aluminum alloy die casting surface: after shot blasting cleaning, the following effects can be achieved.
1、抛丸清理生产率高。由于采用新型的抛丸器以110~260 kg/min的抛射量,抛射速度为50~75 m/s的弹丸抛向工件,在几分钟之内便可完成清理。对于批量较大或尺寸较大的工件可采用多个抛丸器同时抛丸。
1. The productivity of shot blasting is high. Because of the new type of shot blaster, the projectile with a shot volume of 110-260 kg / min and a shot speed of 50-75 M / S is thrown to the workpiece, and the cleaning can be completed in a few minutes. For large batch or large size workpieces, multiple shot blasters can be used for shot blasting at the same time.
2、对零件表面起到清理、增色、光饰作用。经过抛丸处理后,可去除工件表面的附着物、薄边、飞翅、斑渍,消除划痕,使工件呈现基体本色。
2. It can clean, brighten and polish the surface of parts. After shot blasting, the attachment, thin edge, flying wing and spot on the surface of the workpiece can be removed, and the scratch can be eliminated, so that the workpiece presents the original color of the substrate.
3、消除表面应力集中。零件在冷却过程中,由于壁厚不均,冷却速度不一致,导致表面产生应力集中。经抛丸清理后,可改善表面组织结构,消除表面应力(拉应力)集中,提高疲劳强度,并使表面硬度略有提高。
3. Eliminate surface stress concentration. During the cooling process of parts, due to the uneven wall thickness and cooling rate, the surface stress concentration occurs. After shot blasting cleaning, the surface structure can be improved, the concentration of surface stress (tensile stress) can be eliminated, the fatigue strength can be increased, and the surface hardness can be slightly increased.

4、增加表面美感。由于抛射的弹丸为球形丸,抛射到工件上产生细小凹孔,呈球面状,犹如凹面镜一般,在光线照射下,如繁星闪烁,令人赏心悦目。
4. Increase the surface beauty. Because the projectile is spherical, it will produce small concave holes on the workpiece. It is spherical, like a concave mirror. Under the light, it will twinkle like stars, which is pleasing to the eye.
5、提高表面喷涂附着力。抛丸清理后粗糙度可达Ra1.6~6.3 μm,表面积大大增加,同时消除了表面污物,因此对表面喷漆或其它涂料时,其附着力大大增强。
5. Improve the adhesion of surface spraying. After shot blasting cleaning, the roughness can reach Ra1.6 ~ 6.3 μ m, the surface area is greatly increased, and the surface dirt is eliminated. Therefore, the adhesion to the surface painting or other coatings is greatly enhanced.
6、工艺简单,投资节省。由于采用干式抛丸,并配备除尘系统,因此抛丸清理后即可转入下道工序,省却了液体喷砂后冲洗干燥所需的装置费用。
6. The process is simple and the investment is saved. Due to the adoption of dry shot blasting and equipped with dust removal system, the next process can be carried out after shot blasting cleaning, which saves the cost of the device for washing and drying after liquid sand blasting.
