Stamping Presses

A stamping press is a device that is designed and built to operate progressive stamping dies and other types of dies. Stamping presses have the ability to fulfill almost any metal forming or stamping need. Stamping presses can be subdivided into mechanically driven presses and hydraulically driven presses. The most common mechanical presses use an eccentric drive to move the presses ram, whereas hydraulic cylinders are used in hydraulic presses. Mechanical stamping presses offer the advantage of being able to reach higher cycles in a shorter amount of time.

A stamping press is comprised of a press frame, a bolster plate and a ram. The bolster plate is a large, non-moving block of metal upon which the bottom portion of a die is clamped. Large presses, used in automotive applications, have a die cushion integrated in the bolster plate to apply blank holder forces. This process is necessary when a single acting press is used for deep drawing. The ram, also a solid piece of metal that is clamped to the top portion of a stamping die, provides the stroke. This action causes the die to produce parts from the metal being fed through it.
