Description

Technical Field

[0001] The utility model relates to the technical field of aircraft parts production, in particular to an aircraft parts quenching and cooling device. Background Art

[0002] Quenching is a surface heat treatment process that hardens the surface of steel workpieces. The purpose is to improve the hardness, wear resistance and fatigue strength of the workpiece surface, while the core still has high toughness. It is often used for parts such as shafts and gears. During operation, the surface of the workpiece is austenitized by rapid heating, and then immediately quenched to transform the surface structure into martensite, while the core structure remains basically unchanged. After surface quenching, low-temperature tempering is generally performed. According to different heating methods, it can be divided into induction heating surface quenching, flame heating surface quenching, electrical contact heating surface quenching, electrolyte heating surface quenching, etc.; existing quenching furnaces generally use some gas, but too much or too little gas will cause problems, and the temperature of the quenching furnace will also spread to the feed position, causing trouble to the feeding operator and affecting the feeding efficiency; parts are generally cleaned after quenching and cooling, and hot water is generally used for cleaning, but heating water alone will increase energy costs. In view of this, in-depth research on the above issues led to the creation of this case. Utility Model Content
