Stamping dies are classified according to the nature of the process
A. Separate data on closed or open summary lines. Such as punching die, punching die, cutting die, cutting die, trimming die, cutting die, etc.
B. The zigzag die makes the billet or other billet bend along a straight line, and then obtains the die of the workpiece at a certain angle and shape.
C. The die of the figure is a die, which can turn a blank sheet into a hollow sheet, or further change the shape and size of the hollow sheet.
D. Molding die is a kind of die that directly imitates blank or semi-processed workpiece, according to the shape of convex and concave die in the drawing, while the data itself only partially deforms. Such as swelling model, shortening model, swelling model, rough forming model, folding model, plastic mould and so on.
E. Classification according to the degree of process combination.
F. Kunshan stamping die is to use external force to connect the participating parts in a certain order and method, and then form a whole.
Development of Stamping Die Processing
Stamping die is a special process equipment which processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping process. It is called cold stamping die (commonly known as cold stamping die). Stamping is a kind of pressure processing method which uses the die installed on the press to exert pressure on the material at room temperature to produce separation or plastic deformation so as to obtain the required parts. The materials of stamping die are steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low melting point alloy, aluminium bronze, macromolecule material and so on. The die and mould industry has been developing rapidly at the rate of about 15%, and all the components of the die and mould industry enterprises have undergone tremendous changes. In addition to the state-owned professional die and mould factories, the collective, joint venture, sole proprietorship and private enterprises have also developed rapidly.
Function of Stamping Die
In our daily life, we see a lot of stamping parts, such as some special tools for stamping parts made of metal or batch processing of non-metal. For these practical stamping dies, we call them stamping dies.
Die plays an important role in stamping. For those stamping dies that do not meet the requirements, it is difficult to continue the production of batch stamping. Without advanced stamping dies, advanced stamping process can not be achieved. Stamping technology and die, stamping equipment and stamping materials constitute the three elements of stamping process, as long as they are related to each other, stamping parts can be made.
