Used by stamping mold known as the stamping die, die for short.
Die is the material (
Metal or nonmetal)
Batch processing into salt pieces of special tools required.
Is of vital importance to the die in stamping, did not conform to the requirements of punching die, stamping production batch is difficult;
No advanced punching die, stamping process of advanced cannot achieve.
Stamping process and die, stamping equipment and materials to form the three elements of stamping processing, can only draw stamping them together.
Compared with other methods of mechanical processing and plastic processing, stamping processing both in technology and economy has many unique advantages.
Metal stamping parts and castings, forgings, compared with a thin, uniform, the characteristics of light and strong.
Stamping can make other methods are difficult to manufacture with rib stiffener, flanging, ups and downs, or artifacts, in order to improve its stiffness.
Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc.
Cold stamping generally no longer by machining, or only need a small amount of machining.
Hot stamping precision and surface state is lower than the cold stamping parts, but it's still better than the castings, forgings, cutting processing capacity.
Metal stamping parts processing is the use of conventional or special power of stamping equipment, the direct stress and deformation in sheet metal in the mold, and obtained a certain shape, size and performance of the production technology of product parts.
Sheet metal, mold and equipment are the three basic elements of stamping processing.
Cold stamping processing is a kind of metal deformation processing method.
So, called cold stamping or sheet metal stamping, stamping for short.
It is plastic metal processing (
Or pressure processing)
One of the main methods, also belongs to the material molding engineering technology.
