Process classification of metal stamping parts
The metal stamping process can be divided into separation process and forming process (including bending, drawing and forming). The separation process is to separate the stamping part and the blank along a certain contour line in the stamping process, and the quality of the separated section of the stamping part should also meet certain requirements; the forming process is to make the stamping blank plastic deformation under the condition of no damage, and transform it into the required finished product shape, and also meet the requirements of dimensional tolerance of metal stamping parts.
There are two ways of stamping temperature: cold stamping and hot stamping. This depends on the strength, plasticity, thickness, deformation degree and equipment capacity of the material. At the same time, the original heat treatment state and final service condition of the metal stamping parts should be considered.
