Abstract
A spring induction heater assembly is shown and described. The device has a quench tank incorporated into the design. A motor and drive mechanism provide rotation of a spring about one axis from a first position used for loading, to a second position for heat treatment with an induction coil and a third position where the spring is released dropped into a quench tank. Another rotational system is operational to rotate the spring on a spindle in the second or horizontal position while the spring is located between at least two legs of an induction coil. The induction coil provides even heating to the spring coils thereby providing desired changes to the material properties. The quench tank can have an automated system to remove the springs from the quench tank.
