The progressive patterns are made by means of a cutting and forming process using a “die” that contains a series of simultaneous operations on the metal plate fed by strips from a roll of material. The finished metal part develops as the strip of material is subjected to the process through the die for stamping. This transformation is carried out incrementally, or progressively, through a series of stations that cut and shape the material in the desired shape. A die for progressive stamping is a forming device that is designed and constructed to convert a flat metal strip into finished pieces that are shaped according to the requested specifications.
The die is placed in the printing press. As the press moves up, the die opens. When the press moves down, the die closes. The metal moves through the die when it is open, feeding into the die only the precise amount of material in each stroke of the press. The stamping die can modify the metal feed in various forms, such as cutting, bending, coining, grinding, burnishing, extrusion, flanging, embossing and embossing. When the die is closed, it performs its work on the metal and one or more finished pieces are ejected from it. Finished parts can be separated (discrete) or attached to a carrier strip and delivered to disposable or returnable reels.
The components of the die that perform the operations on the material are unique to each piece. The complete die is activated by a mechanical press that moves the die up and down. A feeding mechanism to the press is responsible for feeding the material through the die, conforming it from one station to another with each one of the blows.
If you select progressive die stamping then you can get huge advantages such as speed, quicker setup, make more geometries and less scrap material. When compared to the ancient fabrication method, people can easily setup the time in progressive stamping process. It is based on the frequent feed of material via plenty of die station of the tool. The nature of technique allows people to make more parts within shorter period of time. Actually hard tooling die design is suitable to high volume runs and it is not required die degradation. It allows people to make the robust parts in effective manner. This technique is used in many industries like motorcycle, architecture, medical, power and energy transmission.
