How to classify carbide stamping dies？

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

1. Classification according to process properties

(1) Carbide punching die is a die that separates materials along a closed or open contour line. Such as blanking dies, punching dies, cutting dies, incision dies, trimming dies, slitting dies, etc.

(2) Carbide bending die is a mold that causes the sheet blank or other blanks to bend and deform along a straight line (bending line) to obtain a workpiece with a certain angle and shape.

(3) Carbide drawing die is a mold that converts sheet blanks into open hollow parts, or allows the hollow parts to further change their shape and size.

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

2. Classification according to the degree of process combination

(1) Single-process mold: A mold that only completes one stamping process in one stroke of the press.

(2) Carbide composite mold 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 carbide progressive die (also called a continuous die) has two or more stations in the feeding direction of the blank. In one stroke of the press, two processes are completed at different stations one after another. Molds with one or more stamping processes.
