The basic assumptions of the slip line method are that the thickness of the sheet flange is unchanged, and it is in a state of plane strain, the material is isotropic, there is no hardening, and the influence of friction distribution on plastic flow is not considered. There are three commonly used basic methods. This method is mainly based on some empirical calculation formulas, so its application range is affected, and it is mainly applied to deployable stamping parts with relatively simple shapes (such as rotary parts, bent parts, or stamping parts composed of these simple parts). In general, the method of developing the freeform surface of the plate by experience is a makeshift method, and its accuracy is affected by many factors such as the richness of the user's experience, the empirical formula adopted and the selection of specific process parameters, and its accuracy needs to be further improved.
