内压标准椭圆封头壁厚冲压减薄量的研究

Research on the wall thickness reduction of intrinsic pressure standard elliptical heads due to punching stretch

通过对内压标准椭圆封头冲压成型后的实际壁厚进行测量,同时参考相关行业标准对相应各点进行应力分析,合理解决了选择内压标准椭圆封头壁厚冲压减薄量的问题。

The actual wall thickness of intrinsic pressure standard elliptical heads formed bypunching stretch was measured, and the stress of the corresponding points was analyzed by referring to the relevant industry standards, thus reasonably solving the problem of selecting the wall thickness reduction of intrinsic pressure standard elliptical heads due to punching stretch.
