Classification of stamping dies

Column:Company news Time:2023-12-11
A bending die is a mold that produces bending deformation of sheet metal blanks or other blanks along a straight line (bending curve), thereby obtaining workpieces with a certain angle and shape.

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

Classification based on the nature of the process

(1) A punching die is a mold that separates materials along closed or open contour lines. Such as material dropping die, punching die, cutting die, cutting die, edge cutting die, cutting die, etc.

(2) A bending die is a mold that produces bending deformation of sheet metal blanks or other blanks along a straight line (bending curve), thereby obtaining workpieces with a certain angle and shape.

(3) Stretching die is a mold that makes blank sheet metal into open hollow parts, or further changes the shape and size of the hollow parts.

(4) Forming die is a mold that directly replicates the shape of a blank or semi-finished workpiece into a convex or concave mold according to the drawing, while the material itself only undergoes local plastic deformation. Such as bulging die, shrinking die, expanding die, undulating forming die, flanging die, shaping die, etc.

Classification based on the degree of process combination

(1) A single process mold is a mold that completes only one stamping process in one stroke of a press.

(2) A composite mold has only one workstation, which is a mold that completes two or more stamping processes simultaneously at the same workstation during one stroke of the press.

(3) A progressive die (also known as a continuous die) has two or more stations in the direction of raw material feeding. During one stroke of the press, the die completes two or more stamping processes at different stations in succession.

(4) The transfer mold combines the characteristics of single process molds and progressive molds, and uses a robotic arm transfer system to achieve rapid transfer of products within the mold. This can greatly improve the production efficiency of products, reduce production costs, save material costs, and ensure stable and reliable quality.
