Description

Cold air gun (vortex tube cooling gun)

This creation is about a cold air gun, which is based on the vortex cyclone principle, especially a cold air gun that can generate ultra-low temperature cold air through the air flow theory of an air compressor through a vortex tube, without using any power supply and refrigerant, and can achieve a reduction in the temperature of the workpiece. effect.

In the previous cooling of the workpiece and the processing tool, the temperature was controlled by a large amount of room temperature air with multiple bamboo nozzles and an air compressor. The poor cooling efficiency caused the workpiece to be slightly burnt due to the high temperature.

In the previous cooling of the processed objects and processing tools, a large amount of cooling liquid was used to control the temperature by using multiple bamboo nozzles and pumped by the cooling liquid, which took time to modulate the cooling liquid, and the benefit was not good.

In order to understand the above-mentioned current technical shortcomings, this creation provides a cold air gun based on the vortex cyclone principle, which can generate a low-temperature air flow lower than -28°C than compressed air, which improves tool life, reduces tolerances, improves product accuracy, and reduces use The coolant improves the cleanliness of the machine, and prevents the product from being scorched and burnt due to the heat of the workpiece during the production process and causing micro cracks.

This creation provides a cold air gun (vortex tube cooling gun) which is a device for cooling during mechanical cutting. It includes an air outlet, a silencer tube, O-shaped rubber ring, a silencer tube, and an O-shaped inner cover. It is composed of rubber ring, liner cover, cold air gun liner O-shaped rubber ring, cold air gun liner, cold air gun shell, and adjustment knob. The muffler tube is equipped with a filter cotton (large) and a spring, and the cold air gun is installed inside. The inner tank, filter cotton (small), connecting copper O-type rubber ring, connecting copper, and pressure regulating valve connector are combined. The cold air gun shell corresponds to the inner tank cover installed on the silencer tube. It is equipped with an adjustment knob to adjust the required wind force during mechanical cutting, thereby forming a cold air gun device with better cooling efficiency.
