大直径厚壁筒身成形椭圆度控制技术研究

Study on the control technology of ovality of large-diameter thick-wall barrel forming

本文通过某项目筒体成形尺寸控制研究,阐述了筒身成形下料、预弯,卷制、焊接、热处理各个制造过程中的制造难点,解决了由于卷板机出力不足导致筒体成形椭圆度超差等工艺难题。

To solve the ellipticity deviation that dues to the insufficient output of the plate coiler and other technical problems, the article describes the manufacturing difficulties in the manufacturing process of tube forming blanking, pre-bending, rolling, welding, and the heat treatment. through the size control research of a project about the tube forming.
