What kind of press is used for stamping? What are their characteristics?

Crank press, double-acting stretching press, screw press, fine punching press, telling press, CNC punching die rotary head press, etc. , and check the characteristics accordingly.

The lower part of the press is equipped with an upsetting device. Screw press has the functions of forging machinery such as die forging hammer and mechanical press, and has strong universality, and can be used for die forging, punching and drawing. In addition, the screw press is simple in structure and easy to manufacture, so it is widely used.

Screw press has no fixed bottom dead center, so it can impact and form larger die forgings for many times, and can perform single-action, linkage and inching. Impact force is related to the deformation of the workpiece. When the deformation is large, the impact force is small, and when the deformation is small (such as cold impact), the impact force is large. In these respects, it is similar to a forging hammer. But its striking force is closed by the frame, so it works smoothly, and the vibration is much smaller than that of the forging hammer, so it doesn't need a big foundation.
