Description

Technical Field

[0001] The utility model relates to the technical field of ring forging quenching, in particular to a ring forging quenching device. Background Art

[0002] One of the metal heat treatment processes is to heat the metal product to a certain temperature and then quickly cool it in water, oil or air to improve the hardness and strength of the metal. When producing bearings, a ring forging quenching device is needed. When the quenching device cools the ring forging, the quenching medium cannot evenly cool the ring forging, resulting in uneven surface temperature difference of the ring forging, which easily causes different hardness of the inner and outer surfaces of the ring forging during quenching. In severe cases, it will also cause cracking of the ring forging product, affecting the quality of the product. In addition, the commonly used quenching device has a slow cooling effect, which greatly reduces the work efficiency. Therefore, we have launched a ring forging quenching device.
