Analysis of Technological Parameters of Two-Roll Flexible Winding Technology
Two-roll flexible winding technology was an advanced bending forming technology.With the de-velopment of modern industry,two-roll flexible winding technology had been widely concerned.Based on the principle of two-roll flexible winding process,the influences of parameters such as pressing amount,diameter of rigid roll,diameter of flexible roll,material properties of sheet metal and winding speed on the forming diameter of sheet metal were studied.A two-roll circular finite element model was established by using Abaqus software,a single factor test was carried out on the two-roll flexible circular technology,and a test prototype was designed and manufactured to verify the reliability of the finite element simulation.The results showed that the forming diameter decreased with the increase of pressing amount;the limit forming diameter increased with the increase of rigid roll diameter;the amount of pressing required to reach the ultimate forming diameter decreased with the increase of the diameter of the flexible roll;the forming diameter increased with the increase of yield strength;the limit forming diameter decreased with the increase of Young's modulus;the forming diameter increased with the increase of the winding speed.The research results provided reliable guidance for practical production.
