Stamping die

Stamping die

Stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die).


Classification of stamping die products

Classification of stamping molds based on processing properties

a. A die that separates materials along a closed or open contour line. Such as blanking molds, punching molds, cutting molds, cutting molds, edge cutting molds, sectioning molds, etc.

b. A mold that causes bending deformation of blank or other blank materials along a straight line (bending curve), thereby obtaining a workpiece with a certain angle and shape.

c. A deep drawing die is a mold that converts a blank of sheet metal into an open hollow part, or further changes the shape and size of the hollow part.

d. A forming die is a mold that directly replicates a rough or semi-finished workpiece into the shape of a convex or concave die, while the material itself only produces local plastic deformation. Such as bulging molds, necking molds, expanding molds, undulating forming molds, flanging molds, shaping molds, etc.

e. Riveting die refers to the use of external forces to connect or overlap the participating parts in a certain order and manner, thereby forming a whole


Classification of stamping molds by processing process

a. A mold that completes only one stamping process in one stroke of a press.

b. The composite mold has only one workstation, and in one stroke of the press, it is a mold that completes two or more stamping processes simultaneously on the same workstation.

c. Progressive molds (also known as continuous molds) have two or more workstations in the direction of blank feeding. They complete two or more stamping processes on different workstations in one stroke of the press.

d. The transfer mold combines the characteristics of single process mold and progressive mold, utilizing a robotic arm transfer system to achieve rapid transfer of products within the mold, greatly improving production efficiency, reducing production costs, saving material costs, and ensuring stable and reliable quality.


Classification of stamping molds according to processing methods

According to different product processing methods, molds can be divided into five categories: punching and shearing molds, bending molds, drawing molds, forming molds, and compression molds.

a. Punching and shearing mold: It is used to complete work through shear action, and commonly used forms include cutting die, cutting die, punching die, trimming die, whole edge die, pulling hole die, and punching and cutting die.

b. Bending mold: It is the process of bending flat hair into an angle shape. Depending on the shape, accuracy, and production capacity of the parts, there are various forms of molds, such as ordinary bending dies, cam bending dies, curling dies, arc bending dies, bending and punching dies, and twisting dies.

c. Drawing mold: Drawing mold is the process of making a flat rough embryo into a seamless container with a bottom.

d. Forming mold: Refers to the use of various local deformation methods to change the shape of the hair embryo, which can be in the form of a convex forming die, a rolling edge forming die, a necking forming die, a hole flange forming die, and a circular edge forming die.

e. Compression mold: It uses strong pressure to make the metal wool flow and deform into the desired shape. There are various types of compression molds, including extrusion dies, embossing dies, stamping dies, and end pressing dies.
