Finite Element Analysis on Effect knifes Clearance on Shear Planes in Slitting

슬리팅가공에서 전단면에 미치는 나이프 틈새의 영향에 관한 유한요소해석

A slitter, also called a roll slitter or rewinding machine, is a sort of machinery to cut sheet materials in rolls continuously in the longitudinal direction. Recently slitter line users have requiring higher wuality and precision in products in addition to high productivity. In this paper, on effect of clearance on shear planes in slitting of S.K.B(shrinkage Bnad) is performed by using finite element method. The results obtained are as follows: (1)Load stroke curves show decreasing maximum force when increasing the clearance. (2)Effective strain decreases when the clearance increases. (3)Deformation is concentrated along the very narrow shear band.
