自适应压边力拉深模的设计

Design of Drawing Die With Variable Blank Holder Pressur

分析了拉深过程中压边力的真实需求,设计了专门为可供拉深模使用的氮气弹簧配气的阀门,实现了实际"压边力-行程曲线"与理论"压边力-行程曲线"十分接近。特别适合生产批量大、精度要求高,变形条件恶劣的拉深模采用。

Needing of Blank Holder Pressur during the drawing were Analyzed , specialized valve for nitrogen spring was design. Actual ＂Curve of Blank Holder Pressur - Distance ＂ of this die is near to the Theoretical Curve, if the accuracy of a great deal of Product is Strict, and Process is Difficulty, this die is Reasonable
