The science behind the servo press/Servomotor-driven mechanical press spurs a new way of thinking about forming metal

摘要

In stamping, when you get right down to it, it's not about tonnage. It's about maximizing energy, or the machine's ability to deliver tonnage, where it's needed most: between the die and workpiece. And until recently the only way to increase tonnage in a mechanical press was through bigger presses with bigger motors and flywheels. But what if a press delivered tonnage differently? That question spurred a new wave of mechanical press designs. Press-makers removed the main motor, flywheel, and clutch, substituting it all with a servomotor that focused energy only where needed and, in effect, made the ram a controllable axis.
