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

　　1、According to the nature of the process

　　(1)Punching dies separate the material along closed or open contour lines. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die, etc.。

　　(2)Bending dies make sheet blanks or other blanks bend and deform along a straight line (bending line), so as to obtain a certain angle and shape of the workpiece mold。

　　(3)The drawing die is a mold that makes the blank of the sheet material into an open hollow piece, or further changes the shape and size of the hollow piece。

　　(4)The forming mold is a mold that directly copies the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only produces local plastic deformation. Such as bulging die, shrinking die, flaring die, undulating forming die, flanging die, shaping die, etc.。

　　2、Classification according to the degree of process combination

　　(1)Single-step die is a die that only completes one stamping process in one stroke of the press。

　　(2)There is only one station for the compound die. In one stroke of the press, two or more stamping processes are completed on the same station。

　　(3)The progressive die (also called continuous die) has two or more stations in the feed direction of the blank. In one stroke of the press, two or more stampings are completed at different stations one after another Process mold。
