The invention discloses a high-frequency annealing device of a semi-automatic bearing. The high-frequency annealing device comprises a
machine frame and a high-frequency power supply device, wherein the high-frequency power supply device is fixed on a left-side supporting plate of the
machine frame; a feeding device, a rotating device, a lifting device and a discharging device are fixed on the right-side supporting plate of the
machine frame, the lifting device is fixed on the reverse side of the right-side supporting plate of the machine frame, the rotating device is fixed on a push rod of the lifting device, and a rotating shaft of the rotating device is inserted and sleeved in a circular through hole formed in the right-side supporting plate; an
induction coil is mounted on the high-frequency power supply device, and is above the right-side supporting plate, and the
induction coil and the rotating shaft share the same central axis; the feeding device and the discharging device are fixed on the upper plane of the right-side supporting plate, a feed end of a feed plate of the feeding device faces to the circular through hole, and a discharging end of a discharging plate of the discharging device faces to the circular through hole. The high-frequency annealing device can automatically feed to anneal, the
hardness of the inner ring of the bearing is ensured, annealing is even, the secondary
quenching phenomenon is not generated, the
processing quality is increased, and the stability is good.
