Direct Drive Servo Presses

Offered from 88-440 tons, they are equipped with the most up-to-date direct drive servo motor and control technology, designed especially for servo stamping press applications.

The servo motor offers three times the torque than the current market’s servo motor, and 30% higher torque than other direct-drive servo presses. The state-of-the-art servo direct drive technology eliminates down-gearing, belts and unnecessary linkages and has shortest distance of transmission of any manufacturer, helping to maximize torque distribution. A user-friendly Point-On-Demand (P.O.D.) controller provides 8 preset stroke profiles such as pendulum strokes, multiple hits in one stroke, and extended dwell time, as well as free-hand programmability. SEYI’s unique energy-saving storage system eliminates the issue of higher power requirements and power surges.

SEYI Servos are engineered with a ribbed frame construction, offering more rigidity, especially during longer dwells, and less deflection. The hydraulic overload has been removed and replaced with an electronic overload, providing more stable protection when working closer to rated tonnage for long periods of time. The electronic overload is also programmable.

Servo presses have gained increasing popularity in the past five years. By combining both the advantages of a hydraulic press’s fully programmable slide stroke with mechanical press speeds, manufacturers are better able to control tonnage, speed and dwell at any point of entire stroke, thus making it possible to form more complicated geometric parts, better utilize exotic materials, and eliminate many secondary operations. Taping in the die gets easier. Dwell profiles help stampers to eliminate material spring back and make higher quality parts. To program fast ram speeds at die-closing and die-opening segments, and slow ram velocity during the working portion of a single stroke, yields higher production rates while reducing reverse load, prolonging die maintenance cycle time, and reducing stamping noise and vibration.
