Selection conditions and hardness testing methods of stamping materials for heat sink processing: a large part of stainless steel shell belongs to stamping parts, because it is manufactured by stamping process. In addition to process requirements, the corresponding conditions for material selection are also given. Thickness and properties of materials will affect the setting of parameters in stamping, which determines the forming quality of stamping parts.
In addition to the stamping material with stainless steel shell, the elastic discharging plate should be used as far as possible in the actual design, because the operation of the elastic discharging die is more convenient than that of the fixed discharging die, and the operator can see the feeding action of the strip in the die. Moreover, the elastic discharging plate exerts a flexible force on the strip during discharging, which will not damage the surface of the workpiece. Generally speaking, only when the unloading force of the elastic discharging plate is insufficient, the fixed discharging plate will be used when making stamping parts.
