摘要
分析了中间框的成形工艺,计算了工件的展开尺寸、弯曲力及冲孔力。阐述了凸、凹模之间的间隙,介绍了中间框弯曲模具和冲孔模具的结构设计。生产实践证明,模具结构简单实用,工艺过程合理,加工的产品质量好。它适合批量生产。
The forming technology of middle frame was analyzed,and the expanded size of workpiece,bending force and piercing force were calculated.The clearance between the punch and the die was expatiated.Structures of bending die and piercing die for middle frame were introduced.The production proves that the die structure is simple and practical;the technical process is reasonable,and the quality of processed products is good,which fits a great lot production.
