Φ69.85/R175无直段弯管工艺研究

Study on Procedures ofφ69.85/R175 Tube Bending Without Straight Section

介绍厚壁弯管机上使用的φ69.85/R175无直段弯管模的结构与改进设计。经实践证明该弯模结构合理，提高了弯管制造质量。

This paper introduces structure and improved design ofφ69.85/R175 bending die without straight section to be used in thick-wall tube bending machine. Practice proved that the bending die reasonable with tube bending quality improved.
