The induction coil of a device that heats a toolholder (1) inductively for the tool change comprises a shielding collar (27) of magnetizable material which, firstly, concentrates the magnetic flux of the induction coil (13) in a sleeve section (5) of the toolholder (1) which holds the shaft (11) of a rotary tool with a press fit and, secondly, shields the part of the tool shaft (11) that projects out of the sleeve extension (5), in order to facilitate unclamping the tool from the toolholder (1). On its side facing the winding (19) of the induction coil (13) axially, the shielding collar (27) has an outer circumferential surface (31) which widens conically away from the sleeve extension (5) and an axial height (h) which is at least 1.5 times the diameter (d) of the tool shaft (11). The shielding collar (27) runs on all sides at a distance from a yoke shell (23) of magnetizable material which encases the winding (19) of the induction coil (13).

La bobine d'induction d'un dispositif chauffant par induction un porte-outils (1) pour le changement d'outils comporte un rebord de protection (27) en matériau magnétisable. Ce rebord, d'une part concentre le flux magnétique de la bobine d'induction (13) dans une partie de la cosse (5) du porte-outils (1), cette partie maintenant l'axe (11) d'un outil rotatif en un ajustement sans jeu, d'autre part, il protège la partie de l'axe (11) de l'outil sortant de la saillie de la cosse (5), afin de faciliter le desserrement de l'outil hors du porte-outil (1). Sur sa face axialement orientée vers l'enroulement (19) de la bobine d'induction (13), le rebord de protection (27) a une surface latérale extérieure (31) conique, s'élargissant à partir de la saillie de la cosse (5), et une hauteur axiale (h), correspondant à au moins 1,5 fois le diamètre (d) de l'axe (11) de l'outil. Le rebord de protection (27) est de tous côtés espacé d'une enveloppe de culasse (23) en matériau magnétisable, cette enveloppe entourant l'enroulement (19) de la bobine d'induction (13).
