[Prior Art] When the induction heating arbor device is used, the thermal expansion arbor is heated by the induction of the magnetic coil, and after the upper half of the thermal expansion arbor is heated and expanded, the cutter is inserted to be cooled and tightened. This allows the tool to be firmly integrated with the thermal expansion shank. In addition, as shown in CN Patent No. 02803972, "Induction Heating for Tool Central", the induction heating tool holder device heats the thermal expansion arbor by the magnetic lines generated by the sleeve portion, and the magnetizable material. The finished ring member shields the magnetic lines of force 'the magnetic lines of force generated by the sleeve portion can be concentrated for heating the arbor. Although the above-mentioned existing ring member can shield and concentrate the magnetic lines of force for heating the arbor bar, but due to the shape of the beveled surface around the ring member, it is not enough to connect the top end of the arbor bar, so that the reflected magnetic lines of force are still not concentrated enough. , can not achieve the best heating effect. [New content] Since the magnetic mask of the induction heating arbor device is designed to be inclined, it cannot concentrate on the top of the thermal expansion arbor. For &, the main purpose of this creation is to form a wave-shaped reflective shape at the position corresponding to the top of the arbor, so that the magnetic field lines can surely concentrate the heating effect at this point to obtain a better force 1 heat effect. σ M3 6643 9 In order to achieve the above object, the present invention provides a magnetic mask for an induction heating tool holder device, comprising: a fixing base having a disk body and perpendicular to the middle of the disk body. a surrounding structure corresponding to the perforation, an extended structure protruding inwardly of the disc body; and a magnetic shielding member coupled to the bottom of the extended structure in a surrounding form, and forming a reflective shape on the bottom surface, the reflective shape being continuous concave and convex The parent has a wrong waveform and has a plurality of grooves, the inner ends of the grooves being directed toward the intermediate position of the perforations.

The top end produces a heating effect that allows the tool to be tightly coupled to the thermal expansion shank by cooling after being inserted into the top end of the thermal expansion shank. Since the magnetic shielding member which can generate the shielding and the reflection magnetic field line is combined with the bottom surface of the extended structure and is arranged in a surrounding manner, the position is set close to the top of the thermal expansion knife bar plus the magnetic shielding member is set on the bottom surface. The waveform has a reflective shape, so that the magnetic lines of force can be concentrated on the top end portion of the thermal expansion arbor to heat up compared with the inclined reflecting surface, which can improve the heating effect of the induction heating arbor device and is convenient for the user to utilize.
