Background

The method for processing the hole edge or the outer edge of the plate into the whole edge by using the die is called flanging, the new edge can be used for processing a three-dimensional part with a special space shape and good rigidity, and parts which are not assembled with other parts can be manufactured on a stamping part. When large parts are punched, the flanging can be used for improving the plastic flow of the material so as to avoid cracking or wrinkling, and the method is divided into an inner hole flanging, an outer edge flanging, a thinning flanging and the like according to the process characteristics. Because the convex-concave properties of the outer edge of the part are different, the outer edge flanging can be divided into an inward-bent flanging and an outward-bent flanging. When divided by deformation properties. There are stretch type flanges, compression type flanges, and thinned flanges belonging to volume forming. The extension flanging has the characteristics that the material is subjected to tensile stress during deformation, and extension deformation is generated in the tangential direction, so that the thickness is reduced, and the rupture is easy to occur. Such as round hole flanging, outer edge inward bending flanging and the like. The compression type flanging has the characteristics that the material in the deformation area is subjected to tangential compressive stress to generate compression deformation, the thickness is increased, and the material is easy to wrinkle, such as outward bending flanging of the outer edge, and non-circular hole flanging is often formed by combining extension type flanging, compression type flanging and bending.
