拉拔式无芯弯管模型槽的改进

Improvement in the Groove of the Drawing-Typed Tube-Bending Die with No Core

介绍了拉拔式无芯弯管的概念及工艺过程 ,结合生产实践 ,介绍了无芯弯管型槽的设计方法及改进过程 ,弯管模的型槽对管子弯头截面形状起着决定性的作用。

The concept of drawing_typed bending with no core and its technological process were introduced. The method for designing the groove for bending the tube with no core and the improvement process were stated integrating to the practical production. The groove of the tube_bending die plays a decisive role to the shape of the rook section of the tub.
