Deformation process of deep drawing
The coordinate grid test method was used to analyze. During deep drawing, the blank holder first compresses the medium plate blank, and the punch goes down, forcing the material (flange part) under the blank holder to produce plastic deformation and flow into the gap between the punch and the die to form the side wall of the cylinder. After deep drawing, it is found that the bottom mesh is basically unchanged, and the simple wall part changes greatly.
1. the concentric circles with the same original spacing form a circumferential line with the same length and increased spacing. The closer to the cylinder mouth, the greater the spacing.
2. the original radiation lines with equal division become vertical parallel lines with equal spacing.
3. radial elongation deformation and tangential compression deformation of flange material
Summary: the deformation of deep drawing materials mainly occurs in the flange part. The process of deep drawing deformation is essentially a process in which the material at the flange produces plastic deformation under the action of radial tensile stress and tangential compressive stress, and the flange shrinks continuously and turns into the cylinder wall. This degree of deformation is the largest at the outermost edge of the flange.
