SHEET ROLL FORMING METHOD, AND RUNNING CUTTER AND ROUND BENDER APPLIED THERETO

摘要

A sheet roll forming method is disclosed. The sheet roll forming method includes an uncoiling step for uncoiling a coil by an uncoiler provided at a start of a process line, a straightening step for straightening the coil from the uncoiler to be a flat panel, a piercing step for forming holes for various purposes in the panel fed from the straightening step by a piercing press, a sheet roll forming step for cutting the panel to be a sheet with a predetermined dimension by a running cutter and for successively bending the cut sheet to be a shaped beam by a multi-stage roll forming unit, and a bending step for curvature forming the shaped beam to be a shaped product by a round bender.
