Abstract

Roll forming is a 3D deformation complex process.Stiffness of stands and strength of shafts are the preconditions for the production of precision products.However, the existing roll forming equipment cannot meet the requirements of the production for high strength steel or ultra high strength steel.In order to solve the forming problem of high strength steel or ultra high strength steel, it needs to redesign a set of roll forming equipment.The redesign of roll forming equipment not only makes the production cycle too long, but also results in a high cost.So it is not suitable for the production of forming products.In this paper, based on the existing roll forming equipment a new method of roll forming operation is proposed to optimize the production of U shaped products.The influences of the new method on the roll forming products such as mechanical properties, microstructures and surface qualities, have also been discussed, Based on the new warm roll forming operation, numerical simulation has also been carried out.The simulation result of geometry is in good agreement with experimental result.
