摘要
风扇挂钩相对弯曲半径较大,需同时考虑弯曲半径回弹和弯曲角度的回弹。该制件弯曲角度大于180°且头部需卷边,所需工步较多,该模具有多个工步采用复合工步,使模具结构紧凑。模具调试后制件精度符合要求,生产质量稳定。
Fan hook relative bending radius is I jigger,need to consider bending radius and bending springback angle of springback.The parts bending angle is greater than 1800 and head to edge,step required to work more.The die have multiple steps working with composite work,make the die structure is compact.Parts accuracy meets the requirements after die debugging,production quality is stable.
