Abstract

PURPOSE: To reduce deforming quantity and its variance caused by quenching treatment and to improve dimensional accuracy of machinery parts by dipping a material to be quenched of the metal part into coolant and quenching the material to be quenched while shifting the coolant from upside to downside to the material to be quenched.
CONSTITUTION: In a quenching vessel accommodating the coolant 8, a coolant guide cylinder 4 arranging a coolant guide plate 5 is arranged. In the coolant guide cylinder 4, the material 3 to be quenched of gear, etc., accommodated in a quenching basket jig 2 is charged through an elevator cylinder 7. Next, by driving a stirring fan 1 arranged in the coolant guide cylinder 4 with a stirring motor 6, the coolant 8 is shifted so that flow of the coolant 8 is developed from upside to downside to the above quenching material 3. It is desirable that the flowing speed of the coolant 8 is adjusted to about 0.001W1.0m/sec. By this method, the material 3 to be quenched is quenched while avoiding danger of firing and development of soft spot and also the deforming quantity and its variance caused by the quenching treatment can be reduced.
