带筋内套管成形工艺与模具设计

Forming process of ribbed inner sleeve and its die

介绍了4条筋成形模的典型结构,阐述了模具的工作过程,并对凹模及凸模结构的工艺优缺点进行比较,介绍了合模芯的作用及卸件结构的操作流程,可为同类零件设计提供参考。

The die of forming four ribs, being different from the non-directivity of traditional variable-diameter （reducing diameter/enlarging diameter） die of forming pipe parts, had directivity through analyzing the process of forming four ribs on an inner sleeve. The typical structure of the die was presented, the working process was stated, and the merits and de- merits of the die structure was compared. The function of the closing-die core and the op- eration procedures of the demoulding mechanism were presented
