摘要: A FEM model for a failed industrial example of roll forging was established to analyze the generation mechanisms of the mismatch of size and shape of two spring board. To demonstrate the formulation of these defects, the bites condition and contact status between rectangular groove and workpiece during rolling the first and second spring boards were analyzed. Then, a new oval-diamond groove combining oval groove and diamond groove was presented to eliminate these defects. By analyzing field variables under the same deformation degree, the larger friction can be obtained on the contact surface of workpiece and the oval-diamond groove. The physical experiment validates that the oval-diamond groove can eliminate these defects effectively, and the size of part is in good agreement with design requirement. © 2014 Central South University Press and Springer-Verlag Berlin Heidelberg.
