通过对3种不同材料的管材液压冲孔的实验研究,分析管材材料性能对液压冲孔质量的影响.研究表明:不同材料对塌陷形成的影响不同,材料的屈服强度越高,液压冲孔后的塌陷越大.塌陷尺寸随着内压的降低面增大,在同一内压下,沿管长方向塌陷变化较慢,沿垂直管长方向塌陷变化快.不同材料对断口质量的影响不同,材料屈服强度越高,断面质量越好,材料较软时,撕裂现象更明显.

The influence of tube properties on hydropiercing quality was investigated.The results show that the influence of different materials on collapse is dissimilar.The higher the yield strength of the material is,the larger the collapse after the hydraulic punch is.With reducing the internal pressure,the collapse of the size increases.At the same internal pressure,the collapse along the longitudinal direction changes relatively slow,and that along the vertical direction changes quickly.The influence of different materials on the quality of the fracture is different.The higher the yield strength of the material has,the better the quality of the fracture is.When the material is softer,the phenomenon on tear is more apparent.
