Embodiment Construction

[0039] like figure 1 Shown is a method for cleaning aluminum alloy heat sinks, the steps of the method are:

[0040] 1. Rinse the aluminum alloy heat sink with water to remove dirt and aluminum chips;

[0041] 2. Use a degreasing agent to remove oil and impurities on the surface of the aluminum alloy heat sink;

[0042] 3. Alkali washing the aluminum alloy heat sink with sodium hydroxide solution to remove the burrs of the aluminum alloy heat sink after degreasing;

[0043] 4. Use nitric acid and chromic acid solutions to neutralize the alkaline compounds remaining on the surface of the aluminum alloy heat sink after alkaline cleaning, and remove the surface alkaline compounds;

[0044] 5. Use film agent (Gr6) to treat the surface of the aluminum alloy heat sink, so that the surface of the aluminum alloy heat sink is covered with a protective film.

[0045] 6. Dry or dry the aluminum alloy heat sink.

[0046] like Figure 2 to Figure 9 As shown, the device of the method f...

Abstract

The invention relates to a method and a device for cleaning mechanical parts after processing, in particular to a method and a device for cleaning aluminum alloy radiating fins. The steps of the method are that: 1. water is used to flush the aluminum alloy radiating fins to remove dirt and aluminum slag; 2. degreasing agent is used of remove greasy dirt and impurities on the surface of the aluminum alloy radiating fins; 3. sodium hydroxide solution is used to wash the aluminum alloy radiating fins to remove burr on the degreased aluminum alloy radiating fins; 4. nitric acid solution and chromic acid solution are used to neutralize alkali compound left on the surface of the alkali-washed aluminum alloy radiating fins to remove the alkali compound; 5. surfacing agent (Gr5) is used to treat the surface of the aluminum alloy radiating fins to form a protective film covering the surface of the aluminum alloy radiating fins; and 6. the aluminum alloy radiating fins are dried. The invention additionally discloses a device for realizing the method. The invention has the advantages that the cleaning efficiency is improved, the labor is saved and the clearing cost is greatly reduced.

Description

technical field [0001] The invention relates to a cleaning method and equipment after machining of mechanical parts, in particular to a cleaning device and cleaning method for an aluminum alloy cooling fin. technical background [0002] At present, most of the cleaning methods for aluminum alloy heat sinks after machining are still the original manual cleaning. The required cleaning agent is added to the container in each cleaning process, and then the grid or mesh that is smaller than the container is used The shape-shaped box is equipped with aluminum alloy heat sinks and placed in different cleaning agents to stir and clean. After cleaning, it is put into other boxes for drying and blow-drying. Such a manual cleaning method requires a lot of manpower and material resources, and the work efficiency is extremely low. In addition, during the operation, the air pollution and the impact on human health are also quite large. Contents of the invention [0003] The present inv...
