Method and device for forming high-pressure and low-temperature jet flow by cutting coolant

Abstract

The method discloses a method and device for forming high-pressure and low-temperature jet flow by cutting coolant. The method includes that compressed air stored inside an air storage tank is filtered and dried and connected to a tee joint through a hose to divide an output pipe into two branches, air in one branch is cooled by a cooling device to become low-temperature high-pressure air, and inputted into an air inlet end of a pneumatic spray nozzle after being connected with one or more than one tee joint, the air in the other branch is inputted into a well-sealed cutting fluid storage container after pressure in the air is regulated by a pressure regulating valve, the cutting fluid is pressed out, and connected into liquid inlet ends of a plurality of pneumatic spray nozzles after passing one or more than one tee joint prior through the hose, the air and the liquid are mixed outside a jet nozzle to produce high-speed jet flow. By the method, usage amount of cooling lubricating liquid is reduced, cooling and lubricating functions of fluid medium are fully performed, cutting temperature is greatly lowered, and tool durability is conspicuously improved.

Description

[0001] technical field [0002] The invention relates to the technical field of high-efficiency cooling and lubrication, in particular to a cooling method and a cooling device in cutting and grinding. Background technique [0003] At present, most enterprises still use the traditional cooling method, that is, pouring cutting fluid to cool and lubricate the cutting area to reduce the cutting temperature and improve the tool life and processing quality. But cutting fluid has great negative effects: First, it will threaten the health of workers. In order to improve the cooling and lubrication performance, most of the extreme pressure additives added to the cutting fluid are toxic, harmful substances, and even carcinogenic; the second is to cause serious pollution to the environment. , soil and air pollution; thirdly, the cost of cutting fluid accounts for an increasing percentage of processing costs; fourthly, this method has a large flow rate, wastes resources, and has very l...

But cutting fluid has great negative effects: First, it will threaten the health of workers

In order to improve the cooling and lubrication performance, most of the extreme pressure additives added to the cutting fluid are toxic, harmful substances, and even carcinogenic; the second is to cause serious pollution to the environment. , soil and air pollution; thirdly, the cost of cutting fluid accounts for an increasing percentage of processing costs; fourthly, this method has a large flow rate, wastes resources, and has very limited cooling and lubrication effects, which often cannot meet the needs of cooling, lubrication and environmental protection. needs
