Cooling device for cutting process

Abstract

The invention provides a cutting processing cooling device, comprising a low-temperature liquid storage tank 9, a gas mixing room 8, a compressed air filter 3, a pipe joint, a liquid nitrogen conveying pipe, electromagnetic valves 1, 2, 4, a pressure sensor 6, a temperature sensor 7, a control module, a detection module, a computer (industrial computer, micro-computer or singlechip), a display, a keyboard, and a signal line. The low-temperature liquid storage tank 9 is connected with the gas mixing room 8 through a gas conveying pipe and the electromagnetic valve 4; the compressed air is connected with the gas mixing room 8 through the gas conveying pipe, the filter 3 and the electromagnetic valve 2; the low-temperature gas and the normal-temperature gas are mixed in the mixing room; the output of the gas mixing room 8 passes through the gas conveying pipe and the electromagnetic valve 1; the temperature sensor 7 and the pressure sensor 6 in the gas mixing room 8 are connected with the detection module through the signal line; the electromagnetic valve 1, the electromagnetic valve 2 and the electromagnetic valve 4 are connected with the control module through the control signal line; the control module and the detection module are connected with the computer through communication lines.

Description

technical field [0001] The invention is a pollution-free cutting processing cooling device based on the concept of green manufacturing, which can be applied to cutting processing such as turning, drilling, milling and grinding in industrial production. Background technique [0002] With the popularization of numerical control and the improvement of cutting tool manufacturing technology, the processing efficiency of metal cutting machine tools is getting higher and higher, and the resulting cutting heat and tool tip temperature rise are also getting faster and higher. The amount used is also increasing, and its proportion in the processing cost is also increasing, even reaching 15%, which makes the processing cost of mechanical parts gradually increase; in the early 1990s, developed countries focused on metal processing. The impact of the environment has been carefully discussed, and it is pointed out that cutting fluid is a pollution source in the cutting processing industry...

AI Technical Summary

Problems solved by technology

(2) If the cutting fluid is discharged without treatment, it will pollute the environment, pollute the land, water and air

(3) The supply and management cost of cutting fluid, especially the cost of toxic and harmful cutting fluid and chip disposal with cutting fluid is quite high, which greatly increases the production cost

(4) Additives (such as S, Cl) in cutting fluid will cause potential quality accidents of parts, such as intergranular corrosion, etc.

[0003] The use of low-temperature gas instead of cutting fluid can effectively solve the problem of cutting heat in the cutting process without causing pollution, but ordinary devices for delivering cutting fluid cannot meet the needs of delivering low-temperature gas
