INDUCTION HEATING DEVICE, CASING ELEMENT AND METHOD FOR PREVENTING WEAR OF A MAGNETIC FLUX CONDUCTING ELEMENT USING THE CASING ELEMENT

摘要

The invention is based on an induction heating device (68) for shrinking and/or shrinking tools (10) into and/or out of a tool holder (12),an induction heating unit comprising at least one induction coil (14),which is intended to expand at least a part of a tool holder arranged in a receiving region (18) of the induction heating unit (16) during a shrinking and/or shrinking process by heating and having at least one magnetic flux conducting unit (20) for conducting a magnetic flux generated by the induction coil (14), which is at least one, preferably has movable bearing relative to the receiving region (18), and at least to a large extent formed of a ferrite material magnetic flux conductor (22).;It is proposed that the induction heating device (68) has a sheath element (26), which is arranged on the magnetic flux conducting element (22) and which covers the magnetic flux conducting element (22) on at least one side (24) of the magnetic flux conducting element (22), which is facing the receiving region (18) in at least one operating state of the magnetic flux conducting unit (20).
