Energy-Efficient Hydraulic Press Brakes Run Quiet

Gasparini featured its X-Press 165-ton hydraulic press brake with a 3-m bed at Lamiera, the recently held sheet metal-processing tradeshow held in Italy and attended by MetalForming. The exhibited press brake contained Gasparini’s Eco package, which maintains continuous control of the press brake main motor through a vector-control inverter. Instead of rotating at a fixed speed, the motor is continuously modulated. This enables the hydraulic pump to run at low rpms for reduced flow, and then accelerate to top speed when increased flow rate and pressure are required. When the press brake idles, the motor stops, thus reducing energy consumption—by as much as 50 percent as compared to standard versions—as well as oil stress and noise. Even when running at full power, typical machine noise level on the operator side never exceeds 63 dBa, according to company officials.

X-Press-series press brakes feature welded and normalized structures to guarantee maximum stability, and now come equipped with newly designed backgauges .The machines can be configured as stand-alone, or in tandem/tridem/quadrem and integrated in a robotic cell or automated line.
