Used in metal 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.
Metal stamping parts processing is power by means of conventional or special stamping equipment, the deformation of sheet metal in the mould is directly force and deformation, thereby gaining a certain shape, size and performance of the production technology of product parts.
Sheet metal, stamping mould and equipment is processing of the three elements.
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.
Compared with other methods of mechanical processing and plastic processing, stamping processing both in technology and economy has many unique advantages.
Main show is as follows: (
Stamping processing of high production efficiency, and easy to operate, easy to realize mechanization and automation.
This is because the stamping is depend on the die and stamping equipment to complete the processing, ordinary press stroke times per minute can reach dozens of times, high pressure to can reach more than hundreds of times or even one thousand times per minute, and every time stamping stroke can get one piece.
When stamping due to tooling to ensure the accuracy of the size and shape of metal stamping parts, and generally does not destroy the surface of the metal stamping parts quality, and the life of the mould are long, so the stamping quality is stable, good compatibility, has the characteristics of 'the same'.
Stamping machining size range is larger, more complex shape parts, such as small to watch the stopwatch, big to auto longeron, covering parts, etc. , and stamping material hardening effect of cold deformation, the strength and stiffness of stamping was high.
Press generally generated no chip broken material, material consumption is less, and do not need other heating equipment, it is a kind of material, machining method of energy saving, stamping parts of the cost is low.
