Innovations for the future
The revolution in fine blanking press technology

Since the first fine blanking presses were manufactured, the press ram has been directed from the top to the bottom. Despite decades of practical use, the fact cannot be denied that it is exactly this principle of piston guidance which has many disadvantages.




It is necessary, for instance, to install the press site in a pit or on foundations. The interconnected pipework, hoselines and wiring have proven to be very inconvenient, especially on assembly or disassembly for transport. All necessary repair work "in the cellar" are subject to relatively high expenditure. Ram guidance is totally neglected when eccentric loads or follow-on tools are involved



SCHOEN.
We have the courage to turn all of this upside down.

The courage for a total change has been consequently used by us for the entire press construction. The frame has two lateral yokes, two tie rods and an upper part - that is all. An eightfold flat slideway and a mechanically restricted parallel guidance by means of gear shafts allow for a maximum eccentric load. Tie rods which were inserted in hot condition in the guide area highly increase this excellent stability, frame torsion can be excluded. The ram plate is set going by four cylinders in the overarm.
For the first time, on fine blanking presses, ring teeth and ejector plates are hydraulically clamped by the piston. A circular or angular design in association with a ram guide of overdimensioned length provides for the problem-free insertion of follow-on tools - without tipping off.
Moreover you can use our press not only as an automatic machine, owing to the technical concept, but also as a reliable insertion press. Your wish to punch and emboss in parallel without tipping has become reality.

The entry into modern punching
Experienced technology in a new style

- no main cylinder in the machine bed, which provides optimum stability
- 4 main cylinders in the upper part of the press
- no foundation with pit required
- no assembly in a narrow pit
- minimum frame deformation
- hydraulic drive in the machine head
- no follow-up suction of the main cylinder, which enables faster stroke cycle
- no central positive stop, but 4-point positive stop with central powered adjustment,
adjacent to the working area
- therefore optimum parallelism in upper dead centre
- accurately repeatable disconnection due to parallel upper dead centres
- mechanical parallel guidance by means of gear unit
- eightfold flat slideway with overdimensioned length of slideway
- extremely high eccentric loads are possible
- tool change car with simulated press working space, tool removal device - for tool
preparation outside the press
- 2 tool change plates for ring tooth included in basic scope
- 2 tool change plates for pressure pads included in basic scope
- pipelines and cables protected by channels
- No "experiment" by the use of concepts and materials which have been well
tried for years.

The sum of advantages means longer tool lives
