What is a progressive stamp?

Progressive stamp is a method of completed sheet metal feed, usually from a role, through a series of stations. These stations may include a stamp, bending, cutting and other shaping techniques and are performed in a specific order along the tray path. All stations along the road can be machined in one matrix. In such a case, every time to die descends, it will complete all stations simultaneously, but on separate pieces and at different levels of assembly. The last station is usually cutting the finished piece from the supporting "web" of the sheet remaining from previous steps.

There are several types of machining that can be connected to a progressive stamp. One example is the mining that takes its name from the production of currency. It can be used to create accurate relief on a piece of piece. Usually it is a later station along the tray path due to its nature. Other types of stamps, such as punching and deep drawing, can also take place. These strokes can create cuts in an object in a reasonESU called "Piercing". Punches can also create cuts around the object in a process called "blanking".

Piece can also be presented in a deep drawing during the progressive stamp process. In a deep drawing, the baking tray is pushed to the receiver rather than cut it. The metal is bent and stretched and creates an indentation. In order for this process to be considered a deep drawing, it is a typical standard that the depth exceeds the diameter.

bending is distinguished from a deep drawing in that it usually creates the shape of "U" or a canal that is open at both ends. By performing a series of bends on the separate stations along the progressive route for pressing, the sheet can be shaped into a three -dimensional piece. An example of the final bending result is the card on the top of the can with a drink. Depending on the work, bending is likely to be one of the final stations because many other processes to be made are the easiest to reachNY against a flat surface.
