Drawing die: During the drawing process, the sheet of the workpiece with undevelopable curved surface is partially stretched or stretched, so the drawing die is also called drawing die or drawing die by some people. Drawing die is a standard name, and drawing die or drawing die is an alias. There is no difference.

Trimming die is a special blanking die. The main difference between it and the general punching and blanking die is that the shape of the stamping parts to be trimmed is complex, and the position of the parting edge of the die may be any spatial surface; Stamping parts usually have different degrees of elastic deformation; In the process of separation, there is usually great lateral pressure. Therefore, when designing the die, we should consider the stamping direction, the positioning of parts, the alignment of the die, the removal of waste, the removal of parts, the balance of lateral force and so on.

Flanging forming die: a forming die that makes the edge of the plane part or curved part of the blank turn up along a certain curve to erect a straight edge.
