There are many forms of automobile stamping die, and the stamping die is also classified according to the working nature, mould structure and mould material. Generally, it can be classified according to the following main features:

1. According to the nature of the process

A. Blanking die: die that separates materials along closed or open contour lines. Such as blanking die, punching die, cutting die, cutting die, cutting edge die, cutting die, etc.

B. Bending die: a die that causes a sheet blank or other blank to bend along a straight line (bending line) to obtain a certain Angle and shape of the workpiece.

C. Drawing die: it is used to make blank sheet into open hollow parts or to further change the shape and size of hollow parts.

D. Forming mould: it is a mold that directly duplicates and shapes 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 the expansion model, the shrink model, the expansion model, the undulating forming model, the flanging model, the plastic mold and so on.

2. Classification according to the degree of process combination

A. Single working die: only one stamping die is completed in one stroke of the press.

B. Compound die: a die with only one station, which completes two or more stamping processes simultaneously at the same station during the press's one stroke.

C. Progressive die (also known as continuous die) : in the direction of the blank delivery, there are two or more stations. In the one stroke of the press, two or more stamping processes are completed successively at different stations.

3. Classification according to the processing method of products

According to the different processing methods of products, the molds can be divided into five categories: punching and shearing molds, bending molds, extraction molds, forming molds and compression molds.

A. Blanking and shearing die: the blanking die, blanking die, punching die, trimming die, entire die, punching die and punching die are commonly used.

B. Bending mould: it is to bend the flat wool embryo into an Angle shape. According to the shape, precision and production amount of the parts, there are various kinds of molds, such as general bending die, CAM bending die, roll edge die, arc bending die, bending die for bending seam and twist die, etc.

C. Extraction molds: the extraction molds are made from flat wool embryos into seamless container with bottom.

D. Forming mould: refers to changing the shape of the hair embryo by various methods of local deformation, in the forms of convex forming die, flange forming die, neck shrinking forming die, hole flange forming die and flange forming die.

E. Compression mould: it USES strong pressure to make the metal wool embryo flow and deform into the desired shape. Its types include extrusion die, embossing die, stamping die and end pressing die.
