There are many forms of stamping dies, which can generally be classified according to the following main characteristics:

1. Classification according to process attributes

(1) Stamping 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.

(2) Bending the die makes the blank or other blanks bend and deform along a straight line (bending line), thus obtaining a die with a certain angle and shape.

(3) Drawing die is a die that makes the blank of sheet metal into an open hollow part or further changes the shape and size of the hollow part.

(4) The forming die is a die for directly copying and forming a blank or semi-finished workpiece according to the shapes of the male die and the female die, and the material itself only produces local plastic deformation. Such as expanding die, necking die, flaring die, wavy forming die, flanging die, shaping die, etc.

2. Classification according to the degree of process combination

(1) Single-process stamping die A die that only completes one stamping process in one stroke of the printing machine.

(2) The compound die has only one station, and in one stroke of the press, two or more stamping processes are completed at the same station at the same time.

(3) The progressive die (also called the continuous die) has two or more stations in the feeding direction of the blank, and in one stroke of the press, two or more stamping processes are continuously completed at different stations.
