Dynamic sheet metal working
- Combination of electrical performance and hydraulic power
- High positioning accuracy at up to 1,300 strokes per minute
- Dynamic axis control of the stroke
The patented Hybrid Direct Drive Linear (HDDL) punch drive uniquely blends the dynamics and precision of servo-electric linear drives with the power density and stability of hydraulics. Its efficiency and optimized energy management are other compelling features.
The design of the HDDL is ingeniously simple and therefore particularly reliable. Its electric linear motor is directly coupled to a hydraulic linear amplifier designed specifically for stamping applications and operates contact-free and with zero backlash in the operating medium. A smart controller assures the 1:1 translation of the stamping motion.
With a positioning accuracy of 0.01 millimeters or better, the HDDL achieves up to 1,300 strokes per minute in stamping operations and 3,000 strokes per minute in marking operations. Another unique selling proposition is the dynamic speed adjustment of the stroke. This reduces the energy consumption, tool wear and tear, and noise.
