Pump-free type micro-lubricating equipment

Abstract

The invention belongs to the technical field of tool cutting and micro-lubricating, and relates to pump-free type micro-lubricating equipment. The pump-free type micro-lubricating equipment comprisesan air compressing device (1), an air filtering device (2), a pressure detection device (3), a control valve (4), a one-way valve (5), a cooling lubricant container (6), an aerial fog mixing container(7), a flow detection meter (8) and a liquid level detection switch (9). Compressed air flows in a pipeline, strong negative pressure is formed by generated strong airflow, thus, the pump-free type micro-lubricating equipment replaces a pump to suck a cooling lubricant from the cooling lubricant container, the sucked cooling lubricant is atomized under the effect of the strong airflow, and pump-free type micro-lubricating is achieved.

Description

technical field [0001] The invention belongs to the technical field of tool cutting and micro-lubrication, and relates to a pumpless micro-lubrication equipment. Background technique [0002] The tool will generate a lot of cutting heat during cutting. If it is not cooled in time, built-up edge will be formed on the tool, which will lead to serious consequences such as tool cracking, parts scrapping, and equipment damage. Therefore, it is necessary to timely clean the tool during the cutting process. Lubrication and cooling are carried out to avoid the generation of cutting tumors during the cutting process. The traditional method is to use coolant and air cooling to cool the tool during the machining process. The cooling effect of the coolant is good, but the reuse rate is low. Most of it is discarded and wasted together with the aluminum chips, and the price is expensive. Due to the evaporation of water, the concentration ratio of the coolant changes, resulting in a change...

AI Technical Summary

Problems solved by technology

Because the mixture forms mist, the consumption ratio of cooling lubricating oil is very small, so the average cost is lower than the consumption cost of traditional cooling liquid, and it is popular because it has no pollution to the environment and no harm to human health. Many, typical ones such as: "A Minimal Quantity Lubrication System and Method for Machine Tools" applied by Cheng Kangyong et al. (Application No.: 201610360589.5) uses pump oil and compressed air to form aerosol, its disadvantages are obvious, the control system is complicated and Difficult to maintain, difficult to control aerosol concentration

Xu Xuefeng et al.'s "Minimum Quantity Lubrication Method and Device for Cutting Fluid" (Application No.: 201310050221.5) has obvious shortcomings, such as complex control system and difficult maintenance, and high manufacturing difficulty and high cost
