Research on Plastic Deformation of Rolled Pieces of Four-power rolling Mill Based on Deform

Abstract Aiming at the problems of large cross-section size change and low shape position accuracy workpiece rolled by four-power rolling mill, based on analyzing plastic deformation mechanism metal crystals, simulation was carried out deform software to analyze variation section height equivalent stress distribution section. The results show that under action mutual vertical force, with a length about 2mm occurs in local area 45 ° diagonal end section, maximum dimension increases 4.5% relative blank dimension. Its ends both sides is also largest, then gradually decreases tends be stable.
