Description
The technical field is as follows:
the invention discloses a near-dry cutting liquid supply device applied to the field of machining, relates to a liquid supply device in the field of machining, and belongs to a near-dry cutting liquid supply device which atomizes a lubricant through micron-sized micropores and sprays the lubricant to a cutting area at a high speed to realize spray cooling.
(II) background technology:
first, the conventional cutting fluid supply system has the following problems:
(1) the manufacturing cost is high; statistics show that the cost of using cutting fluids accounts for about 7-17% of the total manufacturing cost, while the cost of the fluid supply system (the cost of cleaning and maintenance of the system and the added equipment for protecting the environment from oil mist pollution) accounts for a significant proportion.
(2) The amount of cutting fluid is difficult to control; the traditional cutting fluid supply method uses cutting fluid with larger pressure and flow to cover a cutting area, and when the processing conditions are changed (such as the situations of replacing a workpiece, replacing a cutter and the like), the consumption of the cutting fluid is difficult to adjust.
(3) The resource consumption is large; the traditional supply system device has poor precision of a cooling pump and a liquid valve, is difficult to accurately control the supply of cutting liquid, has no nozzle meeting the requirements of certain precision, uniform lubrication and accurate oil injection, and cannot continuously supply accurate or drop-shaped lubricant to a complex and concentrated lubricating surface, thereby consuming a large amount of resources.
(4) The pollution to the environment is great; the traditional cutting fluid supply system adopts internal circulation in a machine tool, so that the quality of a product is influenced to a certain extent. And the purification degree of the purification device is lower in the machining process, the environmental pollution degree caused by waste liquid and cutting scraps is very high in the cutting machining process, and the corresponding treatment cost is also very high.
(5) The cleaning difficulty is high; the pipelines in the traditional supply system are made of various materials such as stainless steel, copper, rubber and the like, and the trench is formed by plastering cement and is not suitable for chemical cleaning. The cutting fluid flows through the pipe for a long time to form a black scale layer which has certain mechanical strength but is not hard, and the black scale layer causes great difficulty in cleaning.
Secondly, the composition of the cutting fluid and the influence of the cutting fluid on the environment are as follows:
the cutting fluid mainly comprises two types of water base and oil base, wherein the main components of the water base cutting fluid are water, chemically synthesized water or emulsion, wherein rust inhibitors and extreme pressure additives are added; the oil-based cutting fluid comprises various mineral oils, animal oils or complex oils composed thereof as the main component, and optionally various additives such as extreme pressure additives, oily additives, etc. The influence of the cutting fluid on the environment mainly comprises the following aspects:
(1) the influence on the ecological environment; the harm of the cutting fluid to the ecological environment is mainly the pollution of waste cutting fluid (waste oil and waste liquid) generated in the cutting process to water resources. In addition, the cutting fluid used in the cutting process is more or less retained in the chips, the cutting fluid carried by the chips accumulated in a large amount pollutes the soil, and the toxic and harmful components of the cutting fluid also pollute the environment when the chips are recycled.
(2) Impact on occupational health safety and health management; the harm of the cutting fluid to human bodies is firstly the toxicity of the additive; secondly, damage to the skin; and thirdly, the cutting fluid can damage respiratory organs.
(3) Insecurity; because the cutting fluid contains a plurality of additives, the cutting fluid can cause unsafe hidden troubles such as corrosion, rusting, fire and the like to equipment in the using process.

The micro-spraying device 3 comprises an outer vibrating substrate 31, an outer piezoelectric ceramic piece lead 32, an outer piezoelectric ceramic piece 33, an inner piezoelectric ceramic piece lead 34, an inner piezoelectric ceramic piece 35, an outer cavity 36, an inner cavity 37, an inner vibrating substrate 38 and a spraying hole film 39, wherein a gas micro-spraying hole 310 is formed in the spraying hole film 39, and a lubricant micro-spraying hole 311, a lubricant inlet 312 and a gas inlet 313 are formed in the spraying hole film 39.
The micro-spraying device 3 is also composed of an inner micro-spraying device and an outer micro-spraying device, and the inner micro-spraying device is sleeved inside the outer micro-spraying device;
the outer micro-jet consists of an outer vibration substrate 31, an outer piezoelectric ceramic piece lead 32, an outer piezoelectric ceramic piece 33, an outer cavity 36, a gas inlet 313, a gas micro-jet hole 310 and a jet hole film 39; wherein, the outer piezoelectric ceramic plate 33 is bonded on the outer vibration substrate 31 to form a piezoelectric transducer; the outer piezoelectric ceramic leads 32 are respectively bonded to the upper and lower sides of the outer piezoelectric ceramic sheet 33; the outer vibration substrate 31 is bonded on the orifice film 39 to form an outer cavity 36; the gas inlet 313 is provided on the orifice film 39; the gas micro-orifices 310 are arranged in a ring shape and are machined on the orifice film 39.
The inner micro-jet consists of an inner vibration substrate 38, an inner piezoelectric ceramic piece 35, an inner piezoelectric ceramic piece lead 34, an inner cavity 37, a lubricant inlet 312, a lubricant micro-jet hole 311 and a jet hole film 39; wherein, the inner piezoelectric ceramic plate 35 is bonded on the inner vibrating substrate 38 to form a piezoelectric transducer; the inner side piezoelectric ceramic leads 34 are respectively bonded to the upper and lower sides of the inner side piezoelectric ceramic sheet 35; the inner vibrating substrate 38 is bonded to the orifice film 39 to form an inner cavity 37; the lubricant inlet 312 is provided on the orifice film 39; the lubricant micro-jet holes 311 are arranged in a ring shape and are machined on the jet hole film 39, and two lead ports (not shown) are formed on the jet hole film 39 for leading out the inner piezoelectric ceramic sheet lead wires 34.
When the device works, the vibration directions of the two inner and outer piezoelectric ceramic plates 35 and 33 are opposite, so that a coupling action field is generated in the outer cavity 36, and gas is ejected from the gas micro-jet holes 310 at a high speed to achieve the chip removal effect; or only the outer piezoelectric ceramic piece 33 can be electrified to form air injection; the inner piezoelectric ceramic sheet 35 is energized alone to form a liquid jet. The lubricant enters the inner cavity 37 from the lubricant inlet 312 and is sprayed out from the lubricant micro-spray holes 311 under the action of the inner piezoelectric ceramic plate 35, so that the lubricant supply is realized. Gas enters the outer cavity 36 from the gas inlet 313 and is sprayed out from the gas micro-spray holes 310 under the combined action of the inner piezoelectric ceramics 33 and the outer piezoelectric ceramics 35, so that gas supply is realized.
