Abstract
An induction heating device for a shrink-clamping and/or unshrink-unclamping of tools into and/or out of a tool holder, includes: an induction heating unit comprising one induction coil configured, in a shrink-clamping and/or unshrink-unclamping process, to heat-expand a portion of a tool holder arranged in a receiving region of the induction heating unit; a magnetic flux conducting unit comprising one magnetic flux conducting element for conduction of magnetic flux generated by the induction coil; and a bearing unit configured for a movable support of the magnetic flux conducting element, wherein a large portion of all points of the magnetic flux conducting element each have a respective movement path predetermined partially by the bearing unit, wherein each of the movement paths has an essential movement component oriented perpendicularly to a radial direction of the receiving region and at the same time perpendicularly to an axial direction of the receiving region.
