What are the types of metal stamping dies?

Metal stamping dies are an indispensable tool for making metal stamping parts. In fact, metal stamping dies are divided into different metal stamping dies according to different standards. Many people probably don’t know it. Let’s give you a detailed description. Introduce the types of metal stamping dies.

Metal stamping dies can be divided into blanking dies, drawing dies, bending dies, and forming dies according to the nature of the process.

1. Punching die: A die that separates materials along a closed or open outline, such as blanking die, punching die, cutting die, slitting die, trimming die, cutting die, etc.

2. Drawing die: It is a die for making the blank of the sheet into an open hollow part, or to further change the shape and size of the hollow part.

3. Bending mold: A mold for bending and deforming sheet blanks or other blanks along a straight line (bending line) to obtain a workpiece with a certain angle and shape.

4. Forming mold: It is a mold that directly replicates 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.

Metal stamping molds can be divided into single-process molds, compound molds, and progressive molds (also called continuous molds) according to the degree of process combination.

1. Single-process mold: In one stroke of the press, only one stamping process is completed.

2. Compound mold: There is only one station. In one stroke of the press, two or more stamping processes can be completed on the same station at the same time.

3. Progressive die (also called continuous die): In the feeding direction of the blank, there are two or more stations. In one stroke of the press, two or more stations are completed successively in different stations. Die for one or more stamping processes.
