- Range: 100 to 500 Tons
- A stamping press is a metalworking machine tool used to shape or cut metal by deforming it with a die. In simple terms, a stamping press is the modern day equivalent of a hammer and anvil. The difference is that a stamping press uses precision-made male and female dies to dictate the shape of the final product.
- A press has a bolster plate, and a ram. Presses come in various types of frame configurations, H-Frame for stronger higher tonnage applications.
- It is very important to size the press and tonnage based on the type of applications, blanking, forming, progressive or transfer.
- Strong consideration should be given to avoiding off-center load conditions to prevent premature wear to the press.
- The bolster plate is mounted on top of the press bed and is a large block of metal upon which the bottom portion of a die is clamped; the bolster plate is stationary.
- Large presses (like the ones used in the automotive industry) may be equipped with die cushions integrated in the bolster plate to apply blank holder or counter draw forces.
- This is necessary when a single acting press is used for deep drawing. The ram / slide is the moving or reciprocating member that the upper die is mounted to.
- Ram or Slide guidance is a critical element to assure long die life between die maintenance. Different types of slide guides are available, 4 point V-Gibs or 6 point square gibs on smaller presses and 8 point full length slide guides on larger straight side frame presses.
- With the dies and material be fed into the die between the bolster and slide, good press designs must account for plastic deformation, other wise known as deflection when frame design and loads are considered.
