Main feature classification:
1. Classification according to process properties
a. Blanking die: a die that separates materials along a closed or open contour. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die, etc
b. Bending die: a die for bending and deforming a blank or other blank along a straight line (bending curve), so as to obtain a workpiece with a certain angle and shape.
c. Drawing die: it is a die that makes the blank into open hollow parts, or further changes the shape and size of hollow parts
d. Forming die: it is a die that directly copies and forms the blank or semi-finished workpiece according to the shape of the convex and concave die in the drawing, while the material itself only produces local plastic deformation. Such as bulging die, necking die, expanding die, undulating forming die, flanging die, shaping die, etc.
