Stainless steel flip edge in different industries for extensive use, can show good use value and performance in the industry, according to the nature of deformation, flip can be divided into elongated class flip edge and compression class flip edge. The common feature of the elongation class flip edge is that the rough deformation area produces the elongation deformation under the effect of the cutting pull stress, the deformation characteristic belongs to the elongation class deformation, the limit deformation degree is mainly limited by the cracking of the deformation area. The common feature of the compression class flip edge is that, in addition to the metal near the area near the radius of the root of the vertical edge, the rest of the blank deformation area produces a tangentcompression deformation under the action of the tangent pressure stress, the deformation characteristic sits belongs to the compression class deformation, the stress state and deformation characteristics are the same, and the pull depth is the same, The degree of limit deformation is mainly limited by the unstable wrinkle in the blank deformation area. In addition, according to the vertical edge wall thickness whether there is a forced thinning, can be divided into thin turn edge and constant thin edge. According to the roughness of the flip edge and the edge of the workpiece, it can be divided into inner hole (round hole or non-circular hole) flip edge, plane outer edge flip edge and surface flip edge, etc.
