Description

Technical Field

[0001] The utility model relates to the technical field of anti-oxidation storage of aluminum pistons, in particular to a recyclable flexible storage device for aluminum pistons. Background Art

[0002] The piston is a part that can convert the vertical force (kinetic energy) generated by the intense combustion process of fuels such as diesel, gasoline, and natural gas into rotational motion and transmit it to the crankshaft. It has been doing high-speed reciprocating motion, so the inertia of the piston movement process is very obvious. Therefore, the piston should be as lightweight as possible. Aluminum alloy is one of the most widely used materials in the internal combustion engine piston industry. However, aluminum is very active and can easily react with oxygen in the air to generate aluminum oxide, which isolates the air and prevents the matrix from being further oxidized, making it have excellent corrosion resistance. Therefore, in order to obtain a uniform, dense, and consistent color oxide film, aluminum alloy pistons usually need to be anodized.

[0003] In the process of realizing this application, the applicant found that the existing aluminum pistons are required to be shipped directly after being machined and inspected. In order to prevent defects such as corrosion and color spots on the surface of the pistons during storage and transportation, the piston products are usually oiled on the surface and packaged in plastic bags. However, since the storage environment cannot be kept dry and clean during transportation, the appearance of the aluminum pistons will be affected, which is not conducive to sales.
