U型管毛坯展开的理论探讨

Analysis of blank spreading for U-shaped tube

针对U型管弯曲部分的变形情况进行了分析。根据工件的技术要求 ,确定出了工件双向弯曲部位的毛坯展开原则 ,从理论上计算出了该U形弯管件的毛坯展开尺寸 。

The deformation of the U-shaped tube and analysis and according to the technical requirement of the workpiece, the spreading principles of the blank of the bending part in the U-shaped workpiece are determined. The spreading sizes of the blank workpiece are calculated in theory, which provides a basis for practical production.
