摘要
双弹簧是燃料组件定位格架的重要零件，根据双弹簧成形工艺和毛坯尺寸的分析计算，确定了两种工艺和排样设计。同时设计了一付双弹簧斜楔滑块打弯成形级进模。经试冲表明，采用新的成形级进模生产的产品，其各项成形指标均达到技术要求。
According to the process of shaping double spring and the analytic calculation of the expended blank dimension,two kinds of shaping schemes and layout patter ns are determined.In the same way,a pair of inclined wedge for double spring is designed and bent to progressive type shaping die.Through trial ptoduction,it is shown that the shaping indexes of the product punched with the newly designed progressive type shaping die meet the specification requirements.
