FIELD: electricity.
SUBSTANCE: for press fitting and extraction of hot tools from bushing part (3) of accessory for tool fixation, unit (1) of induction coils is suggested, in which several pole shoes (25) from soft magnetic material are arranged along perimeter with the possibility of radial displacement in annular yoke from soft magnetic material. Pole shoes comprises end surfaces (29), which are arranged at an angle to axis (7) of bushing part (3) rotation and placed with provision of linear support contact with conic peripheral surface (31) of bushing part (3), which holds tool (11) with press fitting. To exclude local overheating of bushing part (3), section (39) of end surface (29) parallel to axis is adjacent at outlet side of bushing part (3) tool to section (33) of end surface (29), arranged as inclined relative to axis of rotation (7).
EFFECT: improved operational characteristics.
