Mechanism Study of Shaping's Influences on Accuracy of Roll Forming Products
In order to study the shaping's influences on the accuracy of roll forming products,ex-periments and the finite element method were used to analyze different shaping schemes'influences on the accuracy of products.The forming force,torque,stress and strain were analyzed in the roll form-ing processes of different shaping schemes,to reveal the shaping's influences on the accuracy of roll forming products.The results show that the shaping may reduce the residual stress of the plates,and reduce the influences of the end flare effect on the accuracy of the formed parts.The influences on springback increase with the increase of the forming angle,which means the larger the angle is,the greater the influences of shaping.
