What are the characteristics of the section of automobile stamping parts?

I believe everyone must be familiar with automobile stamping parts, but there will be cross-sections when they are used. What are the characteristics of the cross-sections?

  • First. Rounded belt. The fillet belt, also known as the slump, is caused by the bending and stretching of the surface of the material that is close to the upper die or the lower die but not in contact with the stamping die.
  • Second, the bright belt. The bright band is caused by the upper die cutting into the steel plate, and the material is squeezed into the lower die to produce plastic shearing deformation. Precision stamping is generally the pursuit of a bright band.
  • Third, the fracture zone. The surface of the fracture zone is relatively rough and has an inclination of about 5 degrees, which is caused by the expansion of cracks formed during stamping.
  • Fourth, the burr. The burr is close to the edge of the fracture zone, and the position of the crack is not facing the die edge, but on the side close to the die edge, which will increase when the metal stamping part is pushed out of the die by the lower die.
