The processing speed of the punching machine is 200-250 times/min. The progressive die is used for the punch press, and because the aluminum foil for processing the fins is very thin, punching oil (the industry is called "fin oil" and the traditional mode of soaking the punching oil in the aluminum foil before processing) is needed to be used in advance in the flanging and thinning stretching processes, so that the lubricating effect is achieved, and adverse effects such as quick loss of the material cracking die are prevented. Traditional aluminum alloy fin stamping oil is volatile oily, although processing requirements can be met, VOCs that the oily stamping oil of volatile type caused brings very big pressure to the atmospheric environment to the workman is when the operation punch press contacts fin oil, because hydrocarbon solvent in the fin oil causes staff skin allergy to the degreasing effect of skin easily, causes health hidden danger. Therefore, non-volatile, volatile-free aqueous stamping liquids have also been developed on the market to solve the above-mentioned problems caused by volatile oily stamping oils.

However, when the traditional mode of soaking the aluminum foil in the aqueous stamping liquid before processing is adopted, the aqueous stamping liquid is difficult to popularize in practical production application due to the characteristics of large surface tension (up to 30-40 mN/m), slow volatilization and the like, so that the novel aluminum fin stamping die is urgently needed to be designed to avoid the defect of using the aqueous stamping liquid, and can be normally used in batches and popularized efficiently.
