DUNKES punching and drawing process are designed and supplied as single column, frame or multi-column configurations in accordance with the respective needs of our customers. Frame designs based on finite element modelling is the basis for a torsion resistant steel weldment construction.
Integrating a hydraulic cutting force damper into this cylinder system or on the press bed extends the service life on tools and the frame.
Off-centre forces can be essentially compensated with overextended flat guides, and with a hydraulic parallel support in combination with the cutting force damper elements.
All versions are equipped with various controls and tool clamping systems. Depending on the task, various guide versions such as 8-fold/6-fold flat or column guides are used, in consideration of the tool design and the component geometry. As a matter of course, each flat guide is individually adjustable and can be fine-tuned.
The shown press types and systems will show you a small cross-section from this product segment. Because of the high market requirements on our customers, a significant aspect is that DUNKES is able to offer combined technologies, e.g. punching and drawing in one plant.
Each press is fabricated specifically to your needs. Options such as motion controlled by cushions, press frame open to the rear, active and passive drawing, can be implemented on demand.
