Problems solved by technology

[0002] The current high-pressure air-quenching and air-cooling mechanism is designed in the heating chamber, and is cooled by internal circulation. The space is small and only one heat exchanger can be installed, and the heat exchange effect is poor; and the air-cooling effect is not good, and the cooling speed is accelerated by the inflation pressure. The gas consumption is high, and the pressure is too high, which affects safety; in addition, the fan operates under high pressure, so a high-power fan is required, which consumes a lot of power; and because of the high air pressure, the internal workpiece is easily damaged

Embodiment Construction

[0006] Because the external space is relatively convenient, the number of heat exchangers can be increased to improve heat exchange efficiency, increase the hardenability of the workpiece, and improve the quality. Since the pipeline design is an external circulation, the air flow can be adjusted and controlled by setting valves at will, which also controls the cooling speed of the workpiece.

[0007] The heat dissipation unit can adopt a large-diameter circulating water port, which can be entered and exited separately.

[0008] The fan can be set outside, not affected by the high temperature of the main body.

Abstract

the invention discloses a working piece cooling equipment of vacuum gas-quenching furnace, which is characterized by the following: adopting external-circulating multiple-heat exchanger to realize inner furnace cooling individually; adjusting aerating pressure from 0.6Mpa to 0.2Mpa; improving safety; reducing gas cost.

Description

technical field [0001] The invention relates to an air cooling device, in particular to a workpiece cooling device for a vacuum air quenching furnace. Background technique [0002] The current high-pressure air-quenching and air-cooling mechanism is designed in the heating chamber, and is cooled by internal circulation. The space is small and only one heat exchanger can be installed, and the heat exchange effect is poor; and the air-cooling effect is not good, and the cooling speed is accelerated by the inflation pressure. The gas consumption is high, and the pressure is too high, which affects safety; in addition, the fan operates under high pressure, so a high-power fan is required, which consumes a lot of power; and because of the high air pressure, the internal workpiece is easily damaged. Contents of the invention [0003] The task of the present invention is to provide safe and reliable cooling equipment with good heat exchange effect, energy saving and durability. ...
