https://orcid.org/http://orcid.org/0000-0001-6642-9481
The straightedge lineal roll forming technology is one of the flexible roll forming processes. It has been widely used in high frequency welding pipe production. This paper aimed to research the straightedge lineal roll forming mechanism and explore the steel strip deformation rules. Taken the HFW355 pipe production mill as object, the forming process and stands function were researched. The integrated forming process of Φ273 × 10 mm pipe was simulated by dynamic explicit elastic-plastic finite element method. The straightedge lineal roll forming process is consisted of pre-forming section, straightedge lineal forming section and fin-pass forming section. The equivalent plastic strain variation of strip in each forming section and rolling force distribution of each forming stand were obtained. The simulation result shown that the bigger plastic deformation occurs in the center and on the edge of the strip. The SLF section acted as a link between pre-forming section and fin-pass forming section to make the steel strip transition smoothly. The rolling force of edge bending stand is the biggest in pre-forming section. The plastic deformation of strip is the biggest in fin-pass forming stands. The research results provide a theoretical basis for roll pattern design. The maximum equivalent plastic strain value of the strip is from 0.064 in pre-forming section to 0.091 in SLF forming section until 0.130 and maximum equivalent plastic strain increases is about 42% in straightedge lineal roll forming process.
