Abstract (en)
[origin: EP2556906A1] The device has central forging tools symmetrically arranged about a forging axis and provided with a forging mandrel (3). The forging mandrel includes a mandrel core (7) and mandrel segments (8) that are provided around circumference of the mandrel core and interchangeably held on the mandrel core. The mandrel segments form mold surfaces (9) for a hollow chamber of a hollow body and thermally insulated-arranged opposite to the mandrel core. The mandrel segments are connected to a cooling or heating device and form-fittingly inserted in sectioned grooves of the mandrel core.
