Cold　bending　forming　is　a　complex　forming　process,　and　its　product　quality　is　closely　related　to　the　forming　process　parameters.　To　mitigate　issues　such　as　bulging　and　waviness　arising　from　the　extension　of　the　material　at　the　edges　during　the　forming　process　of　thin-walled　circular　tubes,　a　comprehensive　comparative　analysis　was　conducted　on　four　forming　methods.　This　analysis　determined　that　the　combined　bending　method　is　the　optimal　forming　technique　for　the　equipment.　For　the　impact　of　different　parameters　on　the　equivalent　plastic　strain　distribution　of　the　product　and　the　force　on　the　rollers,　numerical　simulations　were　carried　out　using　the　software　COPRA　(COPRA　FEA　RF　2023.1)　after　designing　the　pattern　diagram　based　on　the　integrated　bending　method.　The　results　showed　that　different　processing　speeds　on　the　equivalent　plastic　strain　distribution　and　work　hardening　of　the　plate　have　little　effect.　As　the　spacing　between　the　upper　and　lower　rollers　increases,　the　equivalent　plastic　strain　of　the　plate　to　a　certain　extent　and　the　value　of　the　moment　of　the　rollers　is　significantly　reduced.　Analyzing　the　performance　characteristics　of　high-strength　steel　materials　from　the　aspects　of　the　thickness　strain　and　cross-sectional　forming　of　the　plate,　this　verifies　the　advantages　of　forming　high-strength　steel　plates.　The　numerical　simulation　results　of　this　study　are　in　good　agreement　with　actual　production　experimental　results.　©　2024　by　the　authors.
