[0016] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0017] like Figures 1 to 4 As shown, a bolt processing cooling device of this embodiment includes an air outlet pipe 1 and an air inlet pipe 2, and the air inlet pipe 2 is connected to the air outlet pipe 1. The air outlet pipe 1 is connected to the main body 3, and a fluid control part 4 is provided in the main body 3. An air outlet channel 41 is provided in the middle of the fluid control part 4, and the air outlet channel 41 is coaxially arranged with the air outlet pipe 1. The end surface of the fluid control part 4 is provided with an air guide groove 42 and an annular groove 43, and the annular groove 43 is arranged around the air outlet channel 41. A plurality of air guide grooves 42 are arranged obliquely, and one end of the air guide groove 42 is connected with the annular groove 43, and the other end is connected with the air inlet pipe 2. The air guide groove 42 is tangent to the annular groove 43, and the air inlet direction of the air inlet pipe 2 is perpendicular to the air outlet channel 41. An exhaust pipe 5 is provided on one side of the main body 3, and the exhaust pipe 5 is coaxially arranged and connected with the air outlet pipe 1. An exhaust regulating device 6 is provided at the end of the exhaust pipe 5, and the exhaust regulating device 6 is used to adjust the gas flow rate, and the regulating device of the prior art can be used. In the above technical scheme, the airflow enters through the air inlet pipe 2, and is merged into the annular groove 43 through a number of air guide grooves 42, which can enhance the airflow rotation effect. Since the size of the air guide groove 42 is small, the gas will be squeezed in the air guide groove 42, and the gas pressure and temperature will increase. The gas rotates in the annular groove 43, and the gas contacts the exhaust pipe 5. The exhaust pipe 5 is made of heat-conducting material and can quickly conduct heat. Part of the gas is discharged through the exhaust pipe 5, and part of the gas is discharged through the outlet channel 41. Since the cross-sectional area of ​​the gas entering the outlet channel 41 becomes larger, the gas pressure is reduced and the temperature drops. Through the above technical scheme, the heat is released by vortex airflow extrusion transfer, and the heat is absorbed by the exhaust pipe. The cooled gas is output through the outlet pipe, which can cool the workpiece and is easy to operate.

[0018] In this embodiment, the outlet channel 41 has an expansion portion 411, and the diameter of the expansion portion 411 is the same as the inner diameter of the outlet pipe 1, so that the volume of the gas expands when passing through the expansion portion 411 during output, and the temperature is further reduced. The exhaust pipe 5 has an exhaust channel 51, and the inner diameter of the exhaust channel 51 is larger than the expansion portion 411. The exhaust regulating device 6 is arranged in the exhaust channel 51, and the exhaust regulating device 6 is threadedly connected to the exhaust pipe 5, so as to facilitate the replacement of the exhaust regulating device 6. The outlet pipe 1 is threadedly connected to the main body 3, and the exhaust pipe 5 is threadedly connected to the main body 1, which is convenient for installation and disassembly. The air inlet pipe 2 is arranged vertically to the main body 3, so that the airflow can enter vertically, which is convenient for forming a vortex airflow. The air inlet pipe 2 is provided with a control valve 7, which is convenient for controlling the air intake.

[0019] A bolt processing cooling device in this embodiment can output the gas after cooling it, which is convenient for the gas to be cooled and output, thereby cooling the workpiece.

[0020] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
