Description

[0001] The present invention relates to an external coolant integrated high-pressure coolant supply apparatus using a cyclone,

The present invention relates to an external coolant-integrated high-pressure coolant supply apparatus using a cyclone, and more particularly to a high-pressure coolant supply apparatus which does not require a separate external coolant pump or a separate bedshore pump, Pressure coolant supply device using a cyclone that improves the contact between the coolant and the magnets.

Generally, a coolant used in a machine tool is continuously injected and circulated by a coolant pump of an external coolant storage tank attached to the side of a machine tool, and is used for cutting, drilling, and boring. It prevents heat and tool wear caused by friction between materials, and prevents material changes due to heat.

However, since a certain coolant is continuously circulated and supplied during the operations such as cutting, drilling, and boring by the machine tool, the proportion of the content of the cutting powder and the content of the foreign material in the coolant increases, This increases the frequency of abrasion and breakage of the cutting tool, shortens the life of the cutting tool, and prevents efficient supply of the high-pressure cutting fluid. In addition, since the content of the cutting powder and the foreign matter is high, there is a problem that the cutting force of the cutting tool is greatly deteriorated and the machining degree of the cutting tool is greatly affected.

Such a conventional coolant supply device for a machine tool requires a high-pressure pump and a motor for supplying an internal coolant to a machining tool of a machine tool. In order to supply a coolant outside the main machine, a separate coolant supply device Pump and motor shall be provided.

Therefore, since a high-pressure pump and a motor are required to supply the internal coolant and the external coolant to the machine tool, there is a problem that the number of expensive parts increases, thereby increasing the manufacturing cost and manufacturing cost.

The external coolant integral type high pressure coolant supply device using the cyclone of the present invention includes a main body 10, a first filter 20, a coolant inlet line 30, a coolant supply pump inlet pressure gauge 40, a sludge outlet line 50, a clean coolant line 60, a high pressure discharge line 70, a pressure pump 80, a motor 90, a second filter 100, a coolant discharge pressure gauge 110, and a bypass valve 130.

The main body 10 is provided with a first filter 20. The first filter 20 is installed in the main body 10 and is connected to a coolant tank (not shown) to receive a coolant including a sludge and to filter a coolant flowing in the coolant tank .

The first filter 20 is made of a cyclone filter. Therefore, the coolant introduced into the first filter 20, which is the cyclone filter through the cool line inlet line 30, is rotated inside the cyclone filter to precipitate the sludge heavier than the coolant to the lower side of the cyclone filter, ). The coolant filtered through the sludge is discharged to the clean cool line 60 connected to the upper side of the cyclone filter.

The first filter 20, which is a cyclone filter, filters the sludge contained in the coolant on the principle of centrifugal force and gravity settling without a filter.

The sludge heavier than the coolant in the coolant flowing into the cool linelet line 30 sinks to the lower side of the cyclone filter and the coolant that is lighter than the sludge is discharged to the upper side of the cyclone filter. Therefore, a large amount of sludge can be filtered without clogging the filter, and thus the replacement time of the filter can be greatly extended.

The coolant sucked into the cyclone filter flows into the cyclone filter and rotates while the centrifugal force acts to subside the sludge to the bottom of the cyclone filter. The filtered clean coolant is introduced into the clean cool line 60 through the upper portion of the cyclone filter .

The motor 90 is connected to the high-pressure pump 80 to drive the high-pressure pump 80.

The second filter 100 is installed in the high-pressure discharge line 70 between the first filter 20 and the high-pressure pump 80 so that the clean coolant, which is primarily filtered in the first filter 20, And is supplied to the high-pressure pump 80 side.

The second filter 100 is made of a magnetic filter.

A coolant nozzle 104 is provided in the filter body 101 to generate a vortex in the coolant injected toward the magnet 103 to improve the contact between the coolant and the magnets 103.

The coolant nozzle 104 is a means for rotating the coolant injected while the coolant injection force is strong. The coolant nozzle 104 is formed with a fastening portion 105 having a thread to be fastened to the high pressure discharge line 70 and a hollow conical body 106 is formed in the one direction from the fastening portion 105 The conical body 106 is formed with a plurality of spray holes 107 through which the coolant is finally sprayed along the spiral direction.

The spiral guide groove 108 coincides with the spray hole 107 arranged in the spiral direction on the outer surface of the conical body 106. The spiral guide groove 108 is formed by a cool And serves to guide vents of the runt in a spiral direction to form a vortex.

The water sprayed through the spiral spray hole 107 and the helical guide groove 108 of the coolant nozzle 104 is sprayed onto the magnets 103 while rotating and forming a vortex so that the coolant is discharged from the magnet 103 So that the iron foreign substance contained in the coolant is reliably filtered.

The discharge pressure measurement gauge 110 is installed in the high pressure discharge line 70 between the high pressure pump 80 and the high pressure discharge port 71 to measure the coolant pressure.

On the other hand, a coolant discharge pressure switch 120 is installed between the high-pressure discharge line 70 and the discharge-pressure gauge 110.

The bypass valve 130 is provided in the clean coolant line 60 between the first filter 20 and the external coolant port 61. When the internal coolant is used during machining of the machine tool, And the excess clean coolant is guided to the external coolant port 61 side.

The bypass valve 130 allows the clean coolant that has passed through the first filter 20 to be supplied only to the external coolant port 61 when the internal coolant is not used during machining of the machine tool.

Meanwhile, the main body 10 can be coated with a perfume material having a function of relaxing the mind and relaxing the stress, thereby improving the health of the worker.

It is preferable that the functional oil is mixed in an amount of 3 to 5% by weight based on the perfume. If the mixing ratio of the functional oil is less than 3 wt%, the effect is insignificant. If the mixing ratio of the functional oil exceeds 5 wt%, the function is not greatly improved, but the manufacturing cost is greatly increased.

Such a perfume material allows the operator to have health promotion such as comforting the operator's mind and relieving stress while operating the high-pressure coolant supply device of the present invention.

Grapefruit in functional oils can be classified as limonene, citral, geraniol, etc. The components of the grapefruit are antioxidants and antioxidants.

Niaouli contains cineol and eucalyptol as main chemical components and it has excellent antiseptic effect such as treatment of skin diseases and respiratory diseases.

Dill is a chemical component such as carvone, eugenol, etc. It can relieve headache and has a good effect to heal wounds.

Ravensara is mainly used for cineol and pinene, and it is effective for treating respiratory diseases such as bronchitis, rhinitis, cough, psychological stress, anxiety and relieving tension.

As the functional oil is coated on the periphery of the main body 10, the operator comforts the operator while the operator operates the high-pressure coolant supply device, relaxes the stress and infuses the worker's vigor, thereby improving the working efficiency , Thereby improving the worker's health.
