CNC - OF (G) - P- I 25 MULTI DIE SHEET FEED PRESS
- AC main drive with static frequency converter, including recuperation of flywheel brake energy.
- Die alignment system with electronic registering.
- Automatic central lubrication with closed circuit.
- Optional automatic pallet exchange system.
- Flexible press center for all types of ends and shells.
- Sheet and coil feed up to 16-out, 250 strokes per minute (spm).
- Material savings through precise feed.
- Manpower savings by direct sheet processing, eliminating strip shearing.
- Flexibility with shortest changeover times.
- Constant countersink depth ensured by hydraulic compensator.
- Hydraulic overload safety device.
- Crankshaft roller bearings.
- Sheet length and angularity monitor.
- Play-free preloaded roller guidance of the ram.
- Sheets are destacked and fed to the prealignment station, with optional roller type sheet lubricator for coating.
- Double sheet detection occurs at the prealignment station.
- Sheets are aligned using the scrolled edge and moved to the alignment station by servo motor-driven rollers.
- After alignment, sheets are fixed by inner carriage grippers and moved synchronously with the press stroke to the first punch position.
- Synchronization is achieved by overlapping sheets without idle stroke.
- Inner carriage feeds the sheet halfway, then outer carriage grippers take over to move the sheet to the last punch position.
- A roller type web ejector pushes the web out of the press.
- Inner carriage grippers fix the sheet in alignment position.
- Both inner and outer carriage grippers have a fluidic type gripper monitor for correct grip verification.
- Transfer occurs after half of the sheet is processed, with inner grippers opening and outer grippers closing during the 50 ms when the sheet is fixed by the closed die.
- Outer grippers guide the sheet to the last punch.
- Carriages are moved by synchronous linear motors, reducing moving parts and extending service-free lifetime.
- System equipped with a double set of dies, requiring care for the first and last punch positions.
- Patented monitor compensates for sheet edges out of angle and length tolerances without clip-out risk.
- Laser sensors monitor the front edge, calculating distance for compensation of misalignment.
- If misalignment exceeds limits, the first punch is skipped.
- Scrolled and unscrolled sheets, 0.1 - 0.5 mm thickness.
- Materials include aluminum, tinplate, and DR-TFS.
- Less than 3 hours, including tool change.
- Ends 9-out to 16-out.
- Various end sizes with specific cutedge and tool numbers, output ranging from 2250 to 4000 epm.
- Maximum speed: 250 spm.
- Capacity: 125 t.
- Drive: Direct, 22 kW.
- Stroke length: 100 mm.
- Max product height: 20 mm.
- Max sheet size: 1250 x 1200 mm.
- Dies: 15.
- Ram adjustment: 15 mm.
- Air supply: 6 bar.
- Height: 4.100 m.

CNC-OF(G)-P-l25 MULTI DIE SHEET FEED PRESS nitons Haar SEQUENCE OF OPERATION The sheets, scrolled or unscrolled, are destacked and fed to the prealignment station. On the way there is an optional rollertype sheet lubricator for double side or single side coating. Also the double sheet detection takes place there. The prealignment station corrects the alignment of sheets which are out of range because of unprecise packed stillages. According to the movement of the preceding sheets, the prealigned sheet is moved in the alignment station by a set of rollers driven by a servo motor. The alignment...

CNC-OF(G)-P-l25 MULTI DIE SHEET FEED PRESS titans Haar SHEET SQUARENESS MONITOR This system is equipped with a double set of dies, which requires a certain care for the first and the last punch of the sheet. These two punch positions are defined by cutting only one set of the die within the sheet. To avoid clipping out, it is required to make sure that the leading edge of the sheet does not touch the second die set. Additionally it is to guarantee, that the blank of the active die set is perpendicular. Especially if the sheet geometry is out of square (which is often the case) or if due to other...
