摘　　要：为提高冲压成型金属零件的拉深质量,对宽凸缘筒形零件从拉深变形和应力应变角度进行分析,探讨产生起皱及拉裂的影响因素.提出系列质量控制措施,包括严格限制坯料的变形参数、模具增设可调节压料力的压料装置、合理选择凹模和凸模圆角半径、结合多种因素确定凸凹模间隙、选择具有良好力学性能和表面质量优良的材料,以及使模具和坯料表面定期润滑、合理安排热处理工艺.这些措施提高了金属零件的拉深成型质量,满足了设计精度要求.In order to improve the drawing quality of stamping forming metal parts,we analyzed the wide flange cylindrical parts from drawing deformation and stress strain angles,discussed the influencing factors of wrinkling and cracking.We proposed series of quality control measures,including limiting the deformation parameters of billet strictly,adding adjustable pressure devices for the mould,selecting the die and punch fillet radius reasonably,identifying punch and die clearance considering a variety of factors,choosing materials with good mechanical properties and excellent surface quality,lubricating mold and billet surfaces regularly,and arranging heat treatment process reasonably.These measures improve the forming quality of metal parts and meet the design precision requirements.
