ABSTRACT:
A device for inductively heating a cylindrical metal surface on an elongated workpiece having a central rotational axis, wherein the cylindrical surface is generally concentric with the axis. The device comprises an inductor having a generally cylindrical coupling surface matching the metal surface, a main support for carrying the inductor, the main support movable between a first position with the inductor spaced substantially from the cylindrical metal surface and a second position with the inductor in its heating position, and an intermediate frame for mounting the inductor onto the support. The intermediate frame comprises a first link having first and second ends, the link mounted on the main support at the first end for pivotal movement about an axis generally parallel to the central axis, a second link, the second link pivotally mounted on the first link for oscillation about an axis above and generally parallel to the central axis, the inductor mounted in the second link and selectively energizing the inductor when it is in its heating position.
