Description

The decay preventive apparatus of a cutting oil}

The present invention relates to a cutting oil rot prevention device, and more particularly, a variety of foreign substances such as lubricants and hydraulic oils, such as lubricating oil or hydraulic oil, which are mixed in water-soluble cutting oil during the operation of various processing dedicated equipment such as machine tools and skimmers and By operating and removing the air pump alternately, it removes various oils and foreign substances at the same time and very effectively to prevent the corruption of cutting oil, and to the cutting oil anti-corrosion device that can be applied to various other equipment as well as processing equipment. It is about.

In general, various dedicated machine tools such as machine tools supply cutting oil from the cutting oil tank in which the cutting oil supply device is installed to prevent the wear of the tool and the deformation of the workpiece due to the processing heat generated during the processing of the workpiece. It is configured to cool the processing part, and when cutting oil is supplied to the processing part and recovered, not only various oils such as lubricating oil and hydraulic oil which are supplied to the operating part of the processing equipment or the guide surface of the feed system, but also the processing dust generated during processing Various foreign matters such as these are mixed into the cutting oil and recovered to the cutting oil tank.

As described above, various oils such as lubricating oil or hydraulic oil mixed into the cutting oil and recovered to the cutting oil tank form an oil film on the upper part of the water soluble cutting oil to block the contact between the cutting oil and the external air, The foreign material sinks to the bottom of the coolant tank gradually and rots itself, so that the coolant inside the coolant tank is stagnant and starts to rot very rapidly in a stationary state without the dedicated machining equipment.

When the cutting oil is corrupted as described above, various problems such as severe odor due to corruption of the cutting oil, deterioration of the quality of the workpiece due to cutting performance of the cutting oil and rusting occur, and thus, expensive cutting oil must be frequently replaced. Not only economic loss, but also a lot of foreign currency was born.

As a conventional cutting oil corruption prevention device for solving the above problems, the oil-water separation device of the cutting oil tank and the cutting oil corruption prevention device in the dedicated equipment for processing are disclosed in Utility Model Publication (Publication No. 1998-053797, Publication No. 1999-011199). Are each described in

Among the conventional cutting oil corruption prevention devices as described above, the oil-water separating device of the cutting oil tank described in the Utility Model Publication (Publication No. 1998-053797) is differentially installed on the lower end side of the cutting oil tank 10, as shown in FIG. The oil-water separation belt 14 is wound around the pulley 13 and the driving pulley 12 provided above, and the lubricant oil from the oil-water separation belt 14 is filtered by the oil guide plate 15 to separate the lubricant oil from the cutting oil. Lubricating oil filtered from the oil guide plate 15 by an intermediate partition 16 provided with an oil and water separator 11, and a lower return hole 16a communicating with the cutting oil tank 10, is provided in the cutting oil tank 10. The lubricating oil storage chamber 18 which flows in is provided, and the upper plate 17 is provided above the intermediate partition 16.

In the oil / water separator of the conventional cutting oil tank having the above configuration, when the lubricating oil filtered from the oil / water separating belt 14 is introduced into the lubricating oil storage chamber 18 by the oil guide plate 15, the cutting oil contained in the lubricating oil is specific gravity. As the oil sinks to the lower part of the lubricating oil storage chamber 18, the cutting oil is recovered into the cutting oil tank 10 through the return hole 16a and the lubricating oil is drain valve 19 installed on the upper side wall of the lubricating oil storage chamber 18. When the drain valve 19 is closed, the overflowed lubricant is recovered back into the cutting oil tank 10 through the upper plate 17 and the intermediate partition 16. By forming the working relationship, the lubricating oil floating on the upper part of the cutting oil is removed to prevent corruption of the cutting oil.

And, among the conventional cutting oil corruption prevention apparatus, the cutting oil corruption prevention apparatus in the dedicated equipment for processing described in the Utility Model Publication (Publication No. 1999-011199), as shown in Figure 2, the pneumatic line 21 of the dedicated equipment for processing Air supply pipe 23 extending from the cutting oil tank 20 to the inside of the cutting oil tank 20 is installed, and the air supply pipe 23 is provided with a solenoid valve 22 which operates in an OFF state of the processing-only equipment. The air supply pipe 23 occupying the inside of the cutting oil tank 20 has a configuration in which a plurality of bubble generating holes 24 for supplying oxygen to the cutting oil are perforated. When the opening 22 is opened, air is transferred from the main pneumatic line 21 to the air supply pipe 23 to supply bubbles (oxygen) to the cutting oil through the bubble generating holes 24 to prevent the corruption of the cutting oil. that to be.

However, the oil-water separator of the cutting oil tank corresponding to the former among the conventional cutting oil corruption prevention devices as described above can remove various oils floating on the cutting oil by the operation of the oil-water separator 11, but the cutting oil tank 10 Since various foreign substances such as processed dust to sink to the bottom of the) can not be removed, these foreign matters continue to accumulate, there was a problem that can not prevent the corruption of the cutting oil generated when the self-corruption proceeds.

In particular, when oxygen is not supplied into the cutting oil tank 10, the processing oil-only equipment is not operated, that is, when the cutting oil inside the cutting oil tank 10 is held in a stagnant state, Even though the separator 11 was in operation, the corruption of the cutting oil due to the decay of the foreign matter was very fast. When the cutting oil was supplied from the cutting oil tank 10 to the processing part of the workpiece again, various foreign substances were mixed into the cutting oil. Since there is a high possibility of being supplied in a state, there is a problem that causes the deterioration of the processed product due to the performance of cutting oil.

In addition, since the driving pulley 12 and the differential pulley 13 of the oil / water separator 11 are operated in a vertical line, the oil buried on the surface of the oil / water separator belt 14 flows downward. When the oil separator 11 is used for a long time, the oil separation belt 14 may be worn due to the wear of the oil separation belt 14 itself and the deflection of the oil separation belt 14 caused by the wear of the oil separation belt 14. 14 is not in close contact with the oil guide plate 15 as a whole and partially spaced apart from the oil guide plate 15, so that the oil guide plate 15 does not completely filter out various oils buried on the surface of the oil-water separation belt 14. There was a problem in that various oils could not be removed from the cutting oil smoothly.

And, in the conventional cutting oil rot prevention device, the cutting oil rot prevention device in the processing dedicated equipment corresponding to the latter merely provides an indirect means for preventing corruption of the cutting oil by supplying oxygen into the cutting oil tank 20, In addition to the various oils such as lubricating oil and hydraulic oil mixed into the cutting oil during the operation of the processing-only equipment, various foreign substances such as processing dust can not be directly removed.

In addition, as a condition for supplying air to the cutting oil tank 20 when the machine is not in operation, the machine is exclusively equipped to detect the operation and stop state of the machine and to control the air supply. Excessive power loss occurs because the power must be on all the time, and when the processing equipment is stopped, the irrationality of always operating the entire plant or the compressor alone to supply air, the loss caused by the air leakage on the middle line, There is a problem that the economic burden is more than the loss caused by the corruption of the cutting oil due to the work to extend the air supply pipe 23 from the main pneumatic line 21 to the cutting oil tank 20.

The present invention is to solve various problems such as oil and foreign matters such as lubricating oil or hydraulic oil mixed in water-soluble cutting oil and various foreign matters such as processing dust by alternately operating the skimmer device and the air pump to solve the above problems, various oils and foreign matters It is a technical task to provide a coolant anti-corruption device that can be removed at the same time and very effectively to prevent corruption of the coolant, and can be applied to a variety of similar equipment as well as dedicated equipment.

In addition, an air pump 52 alternately operates in accordance with the operation of the timer 51 by two relays 54 and 55 installed at predetermined positions inside the main body 30 in the main body 30. And a driving motor 53 are installed, and the air hose 52a which is delivered to the air pump 52 and supplies air to the cutting oil tank 1 passes through one wall of the main body 30 to the outside of the main body 30. It is formed to be exposed by a predetermined length.

In addition, one side of the main body 30 is driven by a drive pulley 41 which rotates in association with the drive motor 53 by the drive shaft 41a, and a support 44 installed to extend below the main body 30. The driven pulley 42, which is supported for rotation, the skimmer belt 43 wound around the drive pulley 41 and the driven pulley 42, and the skimmer belt 43 come into contact with the surface of the skimmer belt 43. The skimmer device 40 which consists of an oil guide plate 45 which filters oil is installed.

The skimmer device 40 is inserted into the support socket 44a and the support socket 44a, which are inclined at a predetermined angle on one side of the main body 30, and the driven pulley 42 is uncoupled. On the support 44 which consists of the round bar 44b which has the tip 44b 'at the front-end | tip, and the coil spring 44c inserted into the round bar 44b between the support socket 44a and the fastener 44b'.

The working relationship of the cutting oil corruption prevention device according to the present invention having the above configuration will be described in detail with reference to FIGS. 6 and 7.

Firstly, the cutting oil decay prevention device according to the present invention is located near the cutting oil tank 1 of various processing-only equipment such as machine tools, and then the driven pulley 42 of the skimmer device 40 is It is to be immersed in the cutting oil stored in the cutting oil tank (1), and several air dispersers 52b are installed in the air hose 52a coupled to the air pump 52 and formed to the outside of the main body 30, 52b is positioned at the bottom of the cutting oil tank 1.

In the above state, the power not shown in the drawing is connected to the main switch 33a of the main body 30, and then the air pump 52 and the driving motor are made using the timer control switch 33b installed on the control panel 33. When the operating time of the 53 is set, and the main switch 33a is turned on, the air pump 52 and the driving motor (according to the respective operating time set in the timer 51) are set. 53) alternately operate in sequence.

The alternating operation of the air pump 52 and the driving motor 53 by the timer 51 as described above is described in detail with reference to the circuit diagram shown in FIG. 7, and the operation of the timer 51 when the initial power is applied. By the air pump 52 may be operated first, the drive motor 53 may be operated first, but this operation sequence itself does not mean much because it is described below is the air pump when the initial power is applied ( 52) will be described as operating first.

When the main switch 33a is ON, the current flows in the lamp 33c and the timer 51, and the lamp 33c lights up to indicate that the lamp 33c is in operation, and the timer 51 Operation is started, and each of the relays 54 and 55 is in an OFF state in which contact points are separated, so that current does not flow in the air pump 52 and the driving motor 53.

In the above state, when a constant signal (Signal) is transmitted from the timer 51 to the relay 54 connected to the air pump 52, the relay 54 is in an ON state where the contact is connected to the lamp 33c '. As the current flows to the air pump 52, the lamp 33c ′ illuminates the operation of the air pump 52 and at the same time, the air pump 52 is operated and the driving motor 53 is operated. The connected relay 55 is maintained in an OFF state where the contact is separated so that no current flows to the driving motor 53.

When the air pump 52 is operated during the operation time of the air pump 52 input to the timer 51 in the above state, the timer 51 is transmitted to the relay 54 connected to the air pump 52. By operating the relay 54 in the OFF state by cutting off the signal, and transmitting the constant signal to the relay 55 connected to the drive motor 53, the relay 55 is operated in the ON state. When the current flows through the lamp 33c "and the driving motor 53, the lamp 33c" lights up to inform the operation of the driving motor 53 and the driving motor 53 is operated.

When the drive motor 53 is operated during the operation time of the drive motor 53 input to the timer 51 in the above state, the timer 51 transmits to the relay 55 connected to the drive motor 53. By operating the relay 55 to the OFF state by blocking the signal, and transmitting the constant signal to the relay 54 connected to the air pump 52 to operate the relay 54 to the ON state. The air pump 52 and the drive motor 53 are operated in order to alternately.

As described above, when the air pump 52 and the driving motor 53 are alternately operated by the operation of the timer 51, the air pump 52 is operated when the air pump 52 is operated as shown in FIG. 6. Air flows through the air hose 52a connected to the air to the air disperser 52b installed at the bottom of the cutting oil tank 1, whereby small bubbles 6 generated in the air disperser 52b are accumulated on the floor. When the air pump 52 is stopped due to the elapse of the time set in the timer 51, the air flows to the upper portion of the cutting oil layer 4 together with the foreign matter from the various foreign matter layers 5 such as processing dust. 6) together with the foreign matter floated to the upper portion is mixed with the oil by the viscosity of various oils such as lubricating oil and hydraulic oil floating on the upper cutting oil layer 4 to form the oil film layer (3).

When the oil film layer 3 is formed while the air pump 52 is stopped by the timer 51 as described above, the driving motor 53 is operated by the timer 51 at about the same time. As shown in the drawing, the drive pulley 41 is fixedly installed to rotate in conjunction with the drive motor 53 by the drive shaft 41a, and the driven pulley 42 has the support socket 44a into which the round bar 44b is inserted. Rotation and support are supported by the support 44 in which the coil spring 44c is inserted between the unfastening stand 44b 'provided at the distal end of the round bar 44b, so that the driving pulley 41 and the driven pulley ( The tension is automatically applied to the skimmer belt 43 by the elasticity of the coil spring 44c along the length of the skimmer belt 43 wound on the skimmer belt 43, and thus the skimmer belt 43 is rotated by the rotation of the drive motor 53. ) Is rotated while being wound around the driving pulley 41 and the driven pulley 42.

As described above, when the skimmer belt 43 is rotated while being wound around the driving pulley 41 and the driven pulley 42, lubricant oil or hydraulic oil constituting the oil film layer 3 formed on the cutting oil layer 4 may be used. The various oils are transported together with various foreign substances such as processed dust by the viscosity of the oil itself, and adhered to the surface of the skimmer belt 43, and the driving pulley 41 and the driven pulley 42 are supported by the support 44. Since the oil is inclined by a predetermined angle in the rotational direction of the skimmer belt 43, the oil buried on the surface of the skimmer belt 43 does not flow down during the rotation of the skimmer belt 43, and various oils and foreign substances The removal efficiency of is increased.

In addition, since the round bar 44b is not inserted into the support socket 44a and is not fixed, the round bar 44b is released by the tension of the skimmer belt 43 and the coil spring 44c compressed by the elastic force. Although somewhat fixed in the portion (44b '), the round bar (44b) is capable of some degree of rotational flow, and the driven pulley (42), which is loosened and supported by rotation (44b'), is similarly to some extent. When the rotational flow is enabled, and a portion spaced between the skimmer belt 43 and the oil guide plate 45 is generated so that a non-uniform tension is applied over the entire width of the skimmer belt 43, the driven pulley 42 By rotating the fluid so that the skimmer belt 43 and the oil guide plate 45 is completely in contact with no spaced apart portion, various oils and foreign substances buried on the surface of the skimmer belt 43 are completely filtered by the oil guide plate 45. You lose.

In addition, even if deflection of the skimmer belt 43 due to wear of the skimmer belt 43 occurs due to the use of the skimmer device 40 for a long time, the skimmer belt 43 may be prescribed by the elasticity of the coil spring 44c. The tension can be maintained, and the separation between the skimmer belt 43 and the oil guide plate 45 generated by the wear of the skimmer belt 43 is also overcome by the rotational flow of the driven pulley 42 as described above.

Since the alternating operation of the air pump 52 and the driving motor 53 as described above is made continuously by the timer 51, various oils and foreign matters are effectively removed from the cutting oil, and the lubricating oil filtered from the oil guide plate 45 B. Various oils such as hydraulic oil are supplied to the oil / water separator 2 through the oil guide plate 45, so that the cutting oil contained in the oil can be separated again and recovered to the cutting oil tank 1 through a pipe not shown in the drawing. .

The operating time of the air pump 52 and the driving motor 53 set to the timer 51 may be adjusted and set appropriately according to the capacity of the cutting oil tank 1, but the air pump 52 and the driving motor ( 53) It is preferable to use a timer 51 which can set the respective operation time up to a maximum of 60 minutes in minutes, and a small air pump 52 having a relatively low discharge pressure of air can be used. In consideration of the capacity of the plurality of air hoses 52a to be combined with one air pump 52 to be compact, several air dispersers 52a are installed in each air hose 52a, the cutting oil tank (1) When it is located in the desired position of the bottom part, even if the capacity of the cutting oil tank 1 becomes somewhat large, it is possible to sufficiently remove the foreign matter that has sunk to the bottom of the cutting oil tank 1.

In addition, if the cutting oil corruption prevention device according to the present invention is connected to a separate power supply from the processing dedicated equipment, not only the operation of the processing exclusive equipment, but also when the processing dedicated equipment is stopped or even in the summer when the corruption is severe, Except for the fact that it is operated repeatedly all the time, it is possible to effectively prevent the corruption of the cutting oil and to remove various oils and foreign substances contained in the cutting oil at the same time and very effectively. Supplying to the processed part does not reduce the quality of the processed product.

In addition, it can be used immediately by connecting to 220V (volt) single-phase power supply without installing additional equipment, and it is very economical because the electricity consumption is extremely low, and the device itself is light and the size can be miniaturized. As well as a variety of processing-only equipment such as, it is possible to install and apply very easily to other similar equipment.

As described above, the cutting oil corruption prevention device according to the present invention simultaneously removes various oils and foreign substances contained in the cutting oil by alternately operating the skimmer and the air pump to remove various oils and foreign substances mixed in the water-soluble cutting oil. It effectively removes the cutting oil and prevents the corruption of the cutting oil, and even if the recycled cutting oil is supplied to the processing part, it does not reduce the quality of the processed product.It can be connected to a separate power source from the equipment for exclusive use, and the device itself can be used. Being lighter and smaller, it is possible to reduce the economic burden such as excessive power loss and plumbing work, and at the same time can be applied to a variety of other equipment as well as dedicated equipment.
