Devices for forming components having cavities

A device for electromagnetic forming of components having a cavity with a longitudinal axis of extension, the device comprising:

• a core that extends along a central axis and is configured to be fitted into the cavity to carry out a forming operation on a component;
• wherein the core is configured to be pulled out of the cavity after the forming operation,
• wherein the core comprises a plurality of segments in parallel arrangement,
• wherein the segments are made of non-conductive material, and
• wherein the segments are configured to alternate between a machining configuration, in which the segments are locked together to prepare the core for a machining operation, and an extraction configuration, in which the segments mutually slide to reduce a diameter of the core and to remove the core from the cavity;
• and
• drive means for moving the segments, wherein the drive means is configured to move the segments from the machining configuration to the extraction configuration.
