Schuler Unveils New Twin-Servo Drive Concept

November 30, 2012

Front and center at the Schuler booth at EuroBlech was a display touting the firm’s new TwinServo press, boasting a new drive concept with two decentralized servo motors in the press bed. The design, we were told, enables a more compact press and, since the drives are located in the foundation, greatly reduces noise compared to standard servo-press models. It also improves accessibility and rigidity.

In late September 2012, Schuler presented the prototype of a TwinServo press with a force of 1600 metric tons at its facility in Erfurt, Germany. With a height of 6 m, the new transfer press is much shorter than previous models. Plus, its footprint is smaller and the moving bolsters can be placed closer to the machine to ease die changes.

The innovative design of the TwinServo press, without uprights, also improves access to the die area. Slide movement is handled by four draw rods that apply press force to the end faces of the slide. Compared to conventional designs, this allows greater eccentric loads, say Schuler officials. In addition, the maximum press force can be used right up to the bed edge for forming operations. The two press drives are arranged in the bed so that the draw cushion and scrap chutes can be located almost anywhere near the die-clamping area.

Schuler initially will offer TwinServo technology for transfer- and progressive-die presses rated from 1000 to 3500 metric tons, with a bed length of 5000 to 8000 mm. and bed width of 2200 to 3000 mm.
