Stamping 101: Anatomy of a Mechanical Press

January 15, 2008

By:

Stamped components are made by forming, drawing, trimming, blanking, or piercing metal—in sheet or coil form—between two halves (upper and lower) of a press tool, called a die. The upper member (or members) are attached to slide (or slides) of the press, and the lower member is clamped or bolted to the bed or bolster. The die is designed to create the shape and size of a component. The two halves of the die are brought together in the press. Both force (load) and accuracy are required to achieve the repeatability and tolerance demands.

Komatsu H2F Series Servo Press

The science behind the servo press

January 15, 2008

By:

Flexibility sums up where the servo-driven mechanical press stands in its evolution. Early adopters are seeing that flexibility and asking, "What if?" What if I could control ram motion throughout the stroke and dwell for a certain period at bottom dead center (BDC)? According to sources, those "what ifs" have led to new ways of thinking about forming metal.
