Abstract
Automatic apparatus for the induction hardening of parts of track links includes a frame for supporting the inductors which can oscillate in a horizontal plane above the links so as to enable the induction hardening of links of different shapes and dimensions, by alteration of the oscillating travel of the frame. A completely automatic system is also provided for locking the links in correspondence with the inductors, which is programmable in dependence on the shape and dimensions of the track links supplied to the hardening apparatus.

Claims11
Automatic apparatus for induction hardening of parts of metal objects, comprising a fixed structure, inductor means for induction heating of the parts of metal objects to be hardened in the structure, stepwise conveyor means for advancing the objects past the inductor means, and rapid cooling means for cooling the objects downstream of the inductor means, wherein the inductor means is supported by a frame which is movable during the induction heating in two directions substantially perpendicular to each other in a horizontal plane above the parts of the objects to be hardened, means for reciprocating the frame in the two directions so as to impart to the inductor means during the induction heating a substantially circular movement in the horizontal plane above the parts of the objects to be hardened, and means for moving the frame vertically so as to enable adjustment of the vertical distance between the objects and the inductor means.
