成形模具

Based on the relations among the stress, final wall-thickness of thin-walled tube and the characteristics of tube material, original size, curling radius along with friction condition in a axially-compressed internal inversion process on right-angled fillet die, some analytical discriminants were established for judging if a double-layered tubular piece of aluminum alloy could be steadily formed from a certain-sized round tube via internal inversion process without interference and plastic instability of tube wall, and a method was put forward for determining the maximum and minimum usable curling radius or die fillet-radius for thin-walled tubes in the process.

基于薄壁管直角圆角模轴压内翻过程中各处应力及最终壁厚与管材特性、管坯尺寸、卷曲半径及摩擦条件之间的关系，推出了判别任一铝合金双层管件可否由特定尺寸圆管稳定内翻成形而不出现管壁干涉与塑性失稳问题的解析判别式，指出了确定薄壁管圆角模内翻卷曲半径或模具圆角半径极限值的方法。
