DEVICE FOR CORRECTING SHAPE IN ROLL FORMING SYSTEM

摘要

PURPOSE: A correcting device for a roll forming system is provided to enhance dimensional precision by correcting a deformed shape due to deformed gradient and spring back appearing on a molded beam by pressurizing by rolling contact by controlling pressure detected by each pressure sensor. CONSTITUTION: A correcting device for a roll forming system comprises left and right frames(F1,F3), a left pressurizing unit(50), a right pressurizing unit(60), a lower support unit(70), and an upper pressurizing unit(80). The left and right frames are installed on a base(11) on one side of the rearmost end of a roll former unit. The left pressurizing unit is arranged on the left frame. The left pressurizing unit enables a left side pressurizing roll(51) to makes rolling contact with the left part of a molded beam transferred. The left pressurizing unit pressurizes with given pressure. The right pressurizing unit is arranged on the right frame.
