CA7220轿车薄板冲压件成形分类试验研究

Test and Research on the Classification of Sheet Stampings forming for CA7220 Car

冲压成形分类试验是进行系统的冲压变形研究工作的先决条件。根据冲压件的大小、特征、外形特点和对材料的不同性能要求，可将ＣＡ７２２０轿车车身用薄板生产的３８０种冲压件分为深拉延成形类、胀形－深拉成形类、浅拉延成形类、弯曲成形类和翻边成形类五大类。对每种成形类别进行了初步探讨和提出了成形类别与材料性能的对应关系。

The stamping forming classification is the premise of stamping deformation research.Based on size,shape and material of stampings,380 kinds of sheet stampings for CA7220 car body can be divided into five classes,i.e.,deep drawing forming ,bulging-drawing forming,shallow drawing forming,bending forming and flanging forming.Each of forming classes is disscussed and the corresponding relation between forming class and material property is proposed.
