Modular die cushion systems

The system includes a main cylinder with integrated position measuring technology, accumulators, a hydraulic power unit and a number of manifolds. It features software libraries, and the control unit’s hardware components provide a compact, robust hydraulic system enabling highly dynamic control.

Moog’s design team integrated the manifold flange of the new system directly to the cylinder, where it is connected to the main hydraulic accumulators by a separate adaptor manifold. The system reduces force overshoots, which can cause damage in a press. The Modular Die Cushion System uses customer-specific force profiles to ensure the highest level of accuracy in the drawing process.

“Customers will benefit from our extensive experience in developing motion control technology for presses,” said Sascha Dany, hydraulic systems engineer at Moog Luxembourg. “As a package, the Modular Die Cushion System can save both time and money. Its easy-to-use software enables a longer life for deep-drawing dies, higher system reliability and reduced time required for commissioning the system in the plant.”

Maintenance professionals can easily access the system due to the special mounting of its main components. The system offers flexible layout options for integrating the manifold, and requires comparatively little piping, which helps customers lower maintenance and piping costs.
