Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of metal parts, in particular to a cooling mechanism for heat treatment of metal parts. Background Art

[0002] The cooling process of metal parts heat treatment is one of the key steps in the heat treatment process, which directly affects the performance of metal materials. Steam film stage: The cooling rate in this stage is very low. As the cooling time increases, the temperature of the parts continues to drop, and the stability of the steam film gradually decreases. Finally, the steam film breaks and enters the next stage. When the steam film breaks and disappears, the quenching medium directly contacts the surface of the parts and absorbs a lot of heat from the parts. At this time, the cooling rate is the highest. As the temperature of the parts continues to drop, the boiling phenomenon gradually disappears.

[0003] For example, the patent number disclosed by the China Patent Network is: 202321402555.X, and the patent name is: A cooling device for metal parts processing, comprising: a bottom box; a loading basket, a U-shaped plate is fixed on the bottom box, and the loading basket is arranged on the inner side of the U-shaped plate, for placing metal parts to be cooled; a spray cooling mechanism, for spray cooling the metal parts; a driving mechanism, for driving the loading basket to move back and forth during the spray cooling process so that the metal parts are in a constant shaking state, thereby improving the heat dissipation efficiency; placing the metal parts to be cooled in the loading basket, and continuously spraying cooling water on the metal parts through the spray cooling mechanism to cool them. In this process, the loading basket is driven to move back and forth by the driving mechanism so that the metal parts are in a constant shaking state, thereby improving the heat dissipation efficiency, accelerating the cooling rate of the metal parts, and reducing the cooling time.

[0004] However, the size of the internal spray space in the comparative document is fixed.

The quenching medium directly contacts the surface of the parts, affecting the storage effect of the parts.

[0005] Therefore, it is necessary to design and modify the cooling mechanism used for heat treatment of metal parts. Utility Model Content
