Ключевое слово: «aluminum alloy subframe»

In the cleaning process of the subframe after processing, due to the complex internal structure of the subframe, impurities such as aluminum scraps and oil stains in the cavity are not easy to be cleaned. Nowadays, cleaning liquid is used to clean the subframe, and two problems of incomplete cleaning in the cleaning system and incomplete drying in the subsequent drying system are exited, that is, liquid droplets will remain in the cavity and blind hole of the subframe. In this paper some tools such as function analysis and Su-Field model of TRIZ will be applied to analyze and solve the problem, and the existing cleaning and drying device will be improved. In this way, the cleaning of aluminum scraps and oil stains of the subframe will be realized, and in final, drying of the internal and external of the subframe will be ensured.
