Abstract
A device for electromagnetic forming of components having a cavity may include: a core extending along a central axis and configured to be fitted into the cavity to carry out a forming operation on a component; wherein the core may be configured to be pulled out of the cavity after the forming operation, wherein the core may include a plurality of segments in parallel arrangement, wherein the segments may be made of non-conductive material, and wherein the segments may be 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 alternate the segments between the machining and extraction configurations.
