INFORMATIONEN

Profile

Die Werkzeugsegmente (2, 3 oder 4-Backenwerkzeuge) üben radial auf ein sich drehendes Werkstück Druckkräfte aus. Durch entsprechende Gestaltung der Werkzeugsegmente können unterschiedliche Werkstückformen erzielt werden. Je nach Umformgrad erfolgt dieser Vorgang kalt oder warm. Das Schmiedeverfahren kann für Stähle, Aluminium, Kupfer, Titan sowie weitere metallische Werkstoffe eingesetzt werden.

Performance data

Die Leistungskapazität der Schmiedemaschinen wird individuell dem jeweiligen Werkstück bzw. den zu fertigenden Werkzeugen angepasst. Es lassen sich hier insgesamt Leistungskapazitäten zwischen 600 kN bis hin zu 6.000 kN erzielen. Die Kombination von elektronischen, servo-hdyraulischen sowie pneumatischen Antriebs- bzw. Steuerungssystemen ermöglicht bestmögliche Ergebnisse im Hinblick auf Qualität und Reproduzierbarkeit der Bauteile. Je nach Kapazitätsbedarf werden unterschiedliche Handlingskonzepte, zugeschnitten auf jedes einzelne Produkt, angeboten. Eine doppelseitige, gleichzeitige Bearbeitung von längeren Teilen ist ebenfalls möglich.

Advantages

of forging / hammering

  • Weight optimization: Forging / Hammering enables a targeted distribution of the wall thickness at weight-critical components e.g. for automobile components. Using the forging / hammering technology, parts could be changed from solid to hollow material in many cases.
  • Material savings: Using forging operations with the related material displacementcomponents can be formed to the desired form without material losses. The material input can be reduced destinctively.
  • Safety: Forged / hammered components are distinguished with a homogeneous fibre flow. Differing to machined shapes the forged / hammered components are characterized by higher strength.
  • Reduction of single components: Work pieces, which used to be made of multiple single components and then welded, can be forged of wrought products. Beside of the better material properties, forging / hammering generates also cost savings on storage of single components.

With our know how we are at your disposal to develop new production concepts based on GFU forging / hammering technologies. We support you from the process related part optimization, over designing of the machine concept until the delivery of turn-key production lines.
