摘　　要：为了实现翅片高速冲压的自动化要求,设计了一套精密高速伺服数控冲床辅助机构。重点介绍了辅助机构的整体设计及开卷、浸油、送料、拉料、吸附和集料等装置的设计。通过分析悬臂式结构和开卷张力形成特点,设计出由减速电机、开卷滚筒和装料轴组成的开卷装置;为满足铝箔上油和去除多余油料的要求,设计出一款由辊轴和毛毡组成的浸油装置;为满足冲压初期送料要求,对辊轴送料精度进行分析后设计出由空心辊轴、伺服电机和气缸组成的送料装置;为了满足能够冲压不同翅片要求及避免铝箔涂油后由于粘连现象不利于送料的情况,设计了一个拉料步距可调的拉料机构;根据压差吸附原理、翅片和换热器外形特点,设计出能够吸附和收集翅片的吸附装置和集料装置。A set of servo CNC punching press was designed to realize the precise high-speed automotive stamping of the air conditioner fin. The design of the overall structure of the auxiliary mechanism and the devices of the decoiling, the oil-immersion, feeding, pulling, adsorption and collecting were mainly introduced. The decoiling device combined of reduction motor, decoiling rollers and loading shaft was designed based on the analysis of the feature of the cantilever structure and the forming feature of decoiling tension;the oil-immersion device combined of rollers and felt was designed to meet the requirements of oiling of aluminium foil and removal of excess oil;the feeding device combined of hollow shaft, servo motor and cylinder was designed based on the feeding accuracy analysis of rollers to meet the requirement of feeding aluminium foil at the beginning of stamping process;the pulling device with the adjustable pulling step facility was designed to meet the requirement of different fins＇ stamping and avoid the feeding resistant due to adhesion caused by oiling;the adsorption and collecting devices used for adsorbing and collecting the stamped fins were designed, according to the differential pressure adsorption principle and the shape characteristics of the fin and heat exchanger.
