Abstract
An induction heating device for a shrink-clamping and/or unshrink-unclamping of tools into and/or out of a tool holder has an induction heating unit having at least one induction coil configured to thermally expand at least a portion of the tool holder arranged in a receiving region of the induction heating unit. The induction heating device further has at least one magnetic flux conducting unit for a conduction of a magnetic flux generated by the induction coil, the magnetic flux conducting unit having at least one magnetic flux conducting element. The induction heating device further has a sleeve element, arranged on the magnetic flux conducting element and covering the magnetic flux conducting element on at least one side of the magnetic flux conducting element that faces toward the receiving region in at least one operating state of the magnetic flux conducting unit.
