Then an idea was proposed for the raise of the forming height of straight wall components and the effect was proved in the experiment.

就提高成形直壁件的高度提出了改进意见，并在试验中得到证实。

This paper proposes that: the deformation in stamping design prefabricated hole forming specific height fittings first tee is feasible, but needs to process parameter optimization.

本文主要研究以冲压变形规律设计的预制孔管件一次成形特定高度的三通管是可行的，但需对工艺参数优化。

The vertical wall cylinder part with 0.5 height-diameter ratio can ultimately be formed in the practical manufacture after the forming track, especially the first optimal forming path.

设计了加工轨迹，通过实验研究，对成形路径，尤其是第一道次进行了优化，在此基础上加工获得了高径比为0.5的直壁筒形工件。
