Rapid cooling device for auto spare parts

Abstract

The invention relates to the technical field of cooling devices, in particular to a rapid cooling device for auto spare parts. The rapid cooling device comprises a bottom plate, a high-pressure tank and a liquid outlet device, wherein an outer box body is arranged above the bottom plate through a support, a heat preservation pipe is arranged inside the outer box body, a heat preservation cavity isformed between the heat preservation pipe and the outer box body, a bearing is arranged in the middle of the bottom end of the outer box body, a motor is installed below the bearing, the upper end ofa rotating shaft of the motor penetrates through the bearing to extend into the interior of the heat preservation pipe, and a rotatable workbench and the like are installed at the upper end of the rotating shaft of the motor. According to the rapid cooling device for the auto spare parts, the structure is convenient to assemble, moreover, the structure is stable, liquid nitrogen or carbon dioxideis conveyed to air jetting heads through the liquid outlet device and is jetted out from the air jetting heads in a gaseous mode, due to the fact that a large amount of heat can be absorbed when a liquid is vaporized, the high-temperature auto spare parts can be quickly cooled through the gas jetted out from the air jetting heads, the motor drives the workbench to rotate, so that the auto spare parts are uniformly cooled, and meanwhile, the cooling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cooling devices, in particular to a rapid cooling device for auto parts. Background technique [0002] At present, auto spare parts are the various units that constitute the whole of the car and a product that serves the car. With the improvement of people's living standards, people consume more and more cars, and the market for auto parts becomes bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. Many auto parts such as gearboxes, differential housings, etc. are castings. Automobile castings usually need to be cooled after production. The commonly used cooling method is air natural cooling. The effect of air natural cooling is very good, but the cooling speed is slow. Moreover, a large amount of heat will be generated during the cooling process, making the temperature in the production workshop relatively high, and the air-cooled method usually uses natural wind f...

Many auto parts such as gearboxes, differential housings, etc. are castings. Automobile castings usually need to be cooled after production. The commonly used cooling method is air natural cooling. The effect of air natural cooling is very good, but the cooling speed is slow. Moreover, a large amount of heat will be generated during the cooling process, making the temperature in the production workshop higher, and the air-cooled method usually uses natural wind for cooling, which easily oxidizes metal parts during the cooling process and affects the quality of auto parts.
