Example Embodiment

[0018] The specific implementation of the present invention will be further described below in conjunction with examples. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0019] The present invention is a mirror polishing process for aluminum alloy handles of refrigerator door frames, including the following steps:

[0020] S1: Use alumina sandpaper to manually polish the aluminum alloy handle to make the surface smooth and free of scratches and scratches;

[0021] S2: Before polishing, use a polishing machine to remove the aluminum oxide sandpaper texture left on the surface of the aluminum alloy handle. The temperature of the polishing interface between the polishing machine and the aluminum alloy handle is 70°C, and the speed of the polishing machine is 2000 rpm;

[0022] S3: Use deionized water to clean the remaining dirt on the surface o...

Abstract

The invention discloses a mirror polishing technology for an aluminum alloy handle of a refrigerator door frame. The mirror polishing technology comprises the steps that rough machining is conducted through aluminum oxide abrasive paper, cleaning is conducted through deionized water, and an MCD tool is fixed through a large tool pan so that milling finish machining and ultrasonic cleaning can be conducted on the aluminum alloy handle. According to the mirror polishing technology, the aluminum alloy handle subjected to rough machining is subjected milling polishing through the MCD tool, the technology is easy and convenient to operate and stable, compared with a traditional grinding polishing method, the mirror polishing efficiency is improved, meanwhile, the MCD tool of which the structureis more compact is adopted for milling, the service life of the tool is prolonged, and the polishing machining efficiency is improved; and the large tool pan is adopted to fix the MCD tool so that the aluminum alloy handle can be subjected to milling machine, under the condition that the same mirror effect is achieved, the rotation speed of a rotation main shaft of a milling machine tool is decreased, the load of the rotation main shaft of the milling machine tool is reduced, the service life of the milling machine tool is prolonged, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerator manufacturing, in particular to a mirror polishing process for an aluminum alloy handle of a refrigerator door frame. Background technique [0002] Because of its good high-gloss effect, the mirror aluminum alloy plate is widely used in the decoration industry, especially on the refrigerator door panel or refrigerator door handle. Because of its light specific gravity, it is not easy to be oxidized and discolored, and can be recycled and reused. Advantages, its application prospects are good. At present, the mirror polishing technology of aluminum alloy surface mainly includes chemical polishing, electrolytic polishing, mechanical polishing and their composite polishing methods. Among them, mechanical polishing is a treatment process for obtaining a smooth surface through machine tool processing, but the existing mechanical polishing process for aluminum alloy mirror surface polishing produc...
