The main processes of stamping parts processing in stamping factories are punching, bending and stretching. These three processes have different requirements for stamping materials. Dongguan Fortuna has been committed to precision metal stamping for more than 10 years, and has accumulated rich experience in blanking, bending and stretching. Next, the editor of Dongguan Fortuna will analyze the influence of different materials and these three stamping processes. 

1. Punching

Punching stipulates that the raw material should have sufficient plasticity to ensure that the material does not crack during punching. After punching the soft material, a punched part with a smooth cross section and a small slope can be obtained. After punching, the hard metal stamping material has a large cross section. And the thick material is a ductile material, which is very easy to cause tearing after punching;

2. Bending

Bending and forming materials need to have sufficient plasticity and low strength limit; high plasticity plates are not easy to crack during bending; materials with low strength limit and low elastic mold, the rebound deformation after bending is small, very It is easy to obtain bending parts with accurate dimensions; the metal stamping parts with great ductility must have a large relative bending half warp when bending, otherwise the material is very easy to crack during the whole bending process;

3. Stretching

The drawing process of the material not only stipulates that the deep depth of the drawing is as small as possible, the appearance is as simple and round as possible, but also that the material has good plasticity. Cracking of tensile parts, etc.;
