The paper gives an analysis of the features and modulus of the deformation process by fine-blanking, from which the spherical stress tension and stress. deviation of the deformation region were calculated; it also explains a certain number of phenomena occured in the deforming course. The optimum value of inner angle for V-type ring of pressure plate has been obtained and proved by tests.
