Roll Forming Process

The roll forming is one of the simplest manufacturing processes for meeting the continued needs of various industries. The roll forming is increasingly used in the automotive industry to form High Strength Steel (HSS) and Advanced High Strength Steel (AHSS) for making structural components. In order to reduce the thinning of the sheet product, traditionally the roll forming has been suggested instead of the stamping process. The increased product performance, higher quality, and the lowest cost with other advantages have made roll forming processes suitable to form any shapes in the sheets. In this numerical study, a Finite Element Method is applied to estimate the stress, strain and the thickness distribution in the metal sheet with quadrilateral shape, ribs formed by the 11 steps roll forming processes using a validated model. The metal sheet of size 1,000 × 662 × 1.6 mm taken from SGHS steel was used to form the quadrilateral shape ribs on it by the roll forming process. The simulation results of the 11 step roll forming show that the stress distribution was almost uniform and the strain distribution was concentrated on the ribs. The maximum thinning strain was observed in the order of 15.5 % in the middle rib region possibly due to the least degree of freedom of the material.

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.

In this paper, the high-strength steel three-dimensional roll forming production line prototype is studied. The dynamic differential equations of 3D roll forming machine mechanical systems are established by the principle of dynamic balance. The dynamic differential equations are solved out by using MATLAB with the engineering example finite element simulation data. The dynamic characteristics of the forming process of 1.5mm TRIP590 high-strength steel sheet are obtained by the System response. The results can help to improve the performance of the prototype mechanical systems.
