Description

  The present invention relates to a processing oil particle refining apparatus for refining oil particles in order to prevent an increase in film thickness, rot, or oxidation of oil (processing oil) used for machining a machine.

  Processing oil is widely used for machining such as cutting, pressing, and forging. However, processing accuracy and productivity are increased due to increase in film thickness, decay, or oxidation caused by frequency of use and passage of time. There is a problem of lowering. For example, a cutting oil used for metal cutting or the like increases the cutting resistance and becomes harder as the film thickness increases, which causes a decrease in cutting accuracy and wear of a cutting tool.

  It has already been clarified that such an increase in film thickness, decay, or oxidation of the processed oil occurs as the oil particles increase with the frequency of use or the passage of time. As the means for making the powder finer, there is widely known a refinement means for processing oil particles utilizing the catalytic action, far-infrared radiation, or magnetism of ceramics. In this method, ceramic particles are put into a processing oil tank or the like, and are brought into contact with the processing oil to act to refine the oil particles of the processing oil (for example, Patent Document 1).

  However, there is a problem that it is difficult to effectively refine the oil particles of the processing oil because the processing oil cannot be sufficiently brought into contact with the ceramics simply by introducing the ceramic into the processing oil tank.

In order to promote the magnetic action of ceramics, it is known to add extreme pressure additives such as sulfur, chlorine and phosphorus to processing oils, but these extreme pressure additives deteriorate. Since it is easy and the concentration tends to decrease, there is a drawback that an extreme pressure additive must be added constantly during use in order to maintain a constant concentration.
JP-A-2-29496

  Therefore, in the present invention, even when the amount of the extreme pressure additive used is small, the oil particles of the oil used during the machining of the machine are effectively refined using ceramics to increase the oil film thickness, rot, or oxidize. It is an object of the present invention to provide a processing oil particle refining device capable of improving the efficiency and productivity of machining operations by preventing the above.

(Embodiment 1)
FIG. 1 is a cross-sectional view showing a state in which two processing oil particle refining apparatuses according to Embodiment 1 of the present invention are provided with two ceramics and a turbulent flow generating means in a cylinder. 2 is a cross-sectional view of the first turbulent flow generating means of the processing oil particle refining device shown in FIG. 1, and FIG. 3 is a cross-sectional view of the first turbulent flow generating means shown in FIG. FIG. In FIG. 3, the flow of oil flowing in the first turbulence generating means is indicated by arrows. FIG. 4 is a cross-sectional view of the second turbulence generating means of the processing oil particle refining device shown in FIG.

  As shown in FIG. 1, the processing oil particle refining apparatus A includes a turbulent flow generating means 2 and a ceramic 4 in a cylinder 1 having openings 10 and 11 at both ends. As shown in FIG. 1, the opening 10 has a thread groove 12 for connecting to a screw thread (not shown) or the like provided on a hose that supplies processing oil (not shown). May include a thread groove 13 for connecting to a thread (not shown) provided on a hose for discharging the processing oil. Here, you may provide the said opening parts 10 and 11 in the cover bodies 16 and 17 which can be attached or detached to the said cylinder 1, respectively. If it does in this way, replacement | exchange and maintenance of an internal structural member etc. can be performed easily by opening the cover bodies 16 and 17. FIG. The turbulent flow generating means 2 includes first turbulent flow generating means 20 and second turbulent flow generating means 30 buried in the ceramic 4. The structure of the first turbulent flow generation means 20 will be described below. As shown in FIG. 1, the first turbulent flow generation means 20 is on the upstream side of the second turbulent flow generation means 30.

  The first turbulent flow generation means 20 will be described with reference to FIGS. The first turbulent flow generation means 20 has an inlet 21 on the upstream side and an outlet 22 on the downstream side. The first turbulent flow generating means 20 communicates with the inner flow path 23 communicating with the inlet 21 and the outlet 22. The outer channel 24 is in contact with the channel 23 so as to surround it. As shown in FIG. 2, the end of the inner channel 23 opposite to the end communicating with the inlet 21 (downstream side) is closed, and the outer channel 24 is The end (upstream side) opposite to the end communicating with the outflow port 22 is also closed. A plurality of holes 25 are provided in the wall shared by the inner flow path 23 and the outer flow path 24. As shown in FIG. 3, these holes 25 are inclined in a certain direction. The processing oil that has flowed into the processing oil particle refining device through the opening 10 flows into the first turbulent flow generation means 20 from the inlet 21. The processing oil flowing from the inlet 21 flows into the inner flow path 23 and flows out through the hole 25 to the outer flow path 24. When the processing oil passes through the hole 25, the processing oil swirls as indicated by the arrow shown in FIG. 3 due to the inclination of the hole 25, and flows out from the outlet 22 in this state. As shown in FIG. 2, when the inner diameter of the outer wall of the outer flow path 24 is smaller than the inner diameter of the inlet 21 and the outlet 22, the flow velocity increases when the processing oil flows through the inner flow path 23 and the outer flow path 24. The swirl flow is more likely to occur. However, the present invention is not limited to this, and the inner diameter of the outer wall of the outer flow path 24 and the inner diameters of the inlet 21 and outlet 22 may be made equal.

  The second turbulent flow generation means 30 includes a hollow tube 31 provided in parallel with the processing oil flow path (flow direction). As shown in FIG. 1, the hollow tube 31 is provided with a large number of lateral holes 32. The cross section of the hollow tube 31 is not particularly limited. However, if the cross section has a substantially triangular cross section as shown in FIG. The number of the hollow tubes 31 is not particularly limited, but in this embodiment, two hollow tubes 31 are provided. As shown in FIGS. 1 and 4, the second turbulent flow generating means 30 is provided in the cylinder 1 so as to be embedded in the ceramic 4.

  The processing oil flowing out from the outlet 22 of the first turbulent flow generating means 20 flows into the second turbulent flow generating means 30 as it is. In the second turbulence generating means 30, part of the processing oil flows between the ceramics 4 and the rest flows in the hollow tube 31. As described above, since the hollow tube 31 has a large number of lateral holes 32, the processing oil flows through the lateral holes 32 and turbulently flows back and forth between the ceramics 4 and within the hollow tube 31. With the turbulent flow of the processing oil, the ceramic 4 floats, and the contact between the processing oil and the ceramic 4 increases. The amount of the ceramic 4 is not particularly limited, but about 60% to about 90% of the volume of the cylinder 1 is considered in consideration of both the prevention of clogging of the cylinder 1 and the efficiency of refinement of processing oil particles. preferable.

  Thus, the processing oil that has passed through the ceramic 4 and the second turbulence generating means 30 is discharged from the opening 11.

  In the processing oil particle refining apparatus A, the number of the turbulent flow generating means 2 and the ceramic 4 as one block is not particularly limited, and can be appropriately selected depending on the type of the processing oil that passes through the cylinder. FIG. 1 shows an embodiment having two turbulent flow generating means 2 and ceramics 4 in one block. In the case where a plurality of ceramics 4 and turbulent flow generating means 2 are provided as a single block, as shown in FIG. 1, if they are arranged in series so that their angles are approximately 90 degrees when viewed from the front, It can be made more turbulent.

  In the processing oil particle refining apparatus A, a flat plate provided with a net and a large number of holes may be installed in order to remove foreign matters such as dust mixed in the processing oil flowing inside. For example, as shown in FIG. 1, the upstream side of the first turbulent flow generating means 20, between the first turbulent flow generating means 20 and the second turbulent flow generating means 30, and the second turbulent flow generating means. A net 18 may be provided on the downstream side of 30.

  In this way, the processing oil flows into the processing oil particle refining device from the opening and is turbulent by the turbulent flow generating means including the first turbulent flow generating means and the second turbulent flow generating means. Is discharged from the opening. When the processing oil comes into contact with the ceramic, the oil particles are made finer. However, when the processing oil comes into contact with the ceramic in such a turbulent state, the ceramic can be made to act on the processing oil more efficiently. Processing oil increases in particle size and film thickness with use and passage of time. By bringing oil into contact with ceramics in this way, the oil particles become finer, resulting in increased film pressure, decay, or Oxidation can be prevented, and the efficiency and productivity of machining operations are dramatically improved.

(Embodiment 2)
FIG. 5 is a cross-sectional view of the first turbulent flow generating means of the processing oil particle refining device according to Embodiment 2 of the present invention.

  This processing oil particle refining apparatus A uses the first turbulent flow generating means 50 as shown in FIG. 5 in place of the first turbulent flow generating means 20 in the processing oil particle refining apparatus A of the first embodiment. be able to.

  As shown in FIG. 5, the first turbulent flow generation means 50 has an inlet 51 on the upstream side and an outlet 52 on the downstream side, and a flow path 53 between the inlet 51 and the outlet 52. Have. The flow path 53 has a slanted flat plate 54 provided at an angle.

  As in the first embodiment, the processing oil that has flowed into the processing oil particle refining device through the opening 10 flows into the first turbulent flow generation means 50 from the inlet 51. When the processing oil that has flowed in from the inflow port 51 flows into the flow path 53, the flow direction is changed by the inclined flat plate 54, and the turbulent flow flows as it is from the outflow port 52. The inner diameters of the inflow port 51, the outflow port 52, and the flow path 53 may be equal. However, when the inner diameter of the flow path 53 is smaller than that of the inflow port 51 and the outflow port 52 as shown in FIG. When flowing in the flow path 53, the flow velocity is increased, and turbulent flow is more likely to occur.

  The processing oil flowing out from the outlet 52 moves to the second turbulent flow generation means 30 as in the first embodiment, and is then discharged from the opening 11 to the outside of the processing oil particle refining device A.

  Thus, also in the second embodiment, as in the first embodiment, when the processing oil comes into contact with the ceramics in a turbulent state, the oil particles can be refined more efficiently, and the efficiency of machining work can be improved. Productivity and productivity are dramatically improved.

(Embodiment 3)
FIG. 6 is a cross-sectional view of the first turbulence generating means of the processing oil particle refining device according to Embodiment 3 of the present invention.

  This processing oil particle refining apparatus A is the same as the processing oil particle refining apparatus A of Embodiments 1 and 2, except that the first turbulent flow generation means 20 and 50 are replaced with the first turbulent flow generation as shown in FIG. Means 60 can be used.

  As shown in FIG. 6, the first turbulent flow generation means 60 has an inlet 61 on the upstream side and an outlet 62 on the downstream side, and a flow path 63 between the inlet 61 and the outlet 62. Have. The flow path 63 has a spiral plate 64 inside.

  As in the first and second embodiments, the processing oil that has flowed into the processing oil particle refining device A from the opening 10 flows into the first turbulent flow generation means 60 from the inlet. The processing oil that has flowed in from the inlet 61 flows into the flow path 63, the flow is changed to a swirl flow by the spiral plate 64, and flows out from the outlet 62 as it is. The inner diameters of the inflow port 61, the outflow port 62, and the flow path 63 may be equal. However, when the inner diameter of the flow path 63 is smaller than that of the inflow port 61 and the outflow port 62 as shown in FIG. When the gas flows through the flow path 63, the flow velocity is increased, and a swirl flow is more likely to be generated.

  The processing oil that has flowed out of the outlet 62 moves to the second turbulent flow generation means 30 as in the first and second embodiments, and is then discharged from the opening 11 to the outside of the processing oil particle refining device A.

  Thus, also in Embodiment 3, as in Embodiments 1 and 2, when the processing oil comes into contact with ceramics in a turbulent state, oil particles can be refined more efficiently, and machining work can be performed. Efficiency and productivity are dramatically improved.

  In the processing oil particle refining apparatus A of the present invention, the type of the ceramic 4 is not particularly limited, but is preferably at least one of tourmaline ceramics and electron-emitting ceramics, more preferably titanium oxide ceramics, It is preferable to include at least one of silver ceramic and copper ceramic. Further, the ceramic 4 is preferably sintered into a spherical shape having a diameter of about 5 mm to about 10 mm. A mixture of titanium oxide ceramic, electron-emitting ceramic, and tourmaline ceramic may be used, and the mixing ratio is preferably in the range of about 1: 1: 1 to about 1: 2: 2. Alternatively, silver ceramic, electron-emitting ceramic, and tourmaline ceramic may be mixed and used, and the mixing ratio is preferably in the range of about 1: 1: 1 to about 1: 2: 2.

  In the processing oil particle refining apparatus A of the present invention, when a fungus growth inhibitor is similarly used in addition to the ceramics 4, the anti-corruption effect can be further promoted. As the fungus growth inhibitor, for example, “Environmental Flower” manufactured by Andsui Development Co., Ltd. can be used. This “environmental flower” has a spiral shape in which a ceramic powder and a polyethylene blend are mixed at a ratio of 90% and 10%, and the ceramic powder includes silicon dioxide, aluminum oxide, ferric oxide and the like.

  Further, in the processing oil particle refining apparatus A of the present invention, the flow rate may be controlled by storing the processing oil flowing inside in a tank or the like and supplying or sucking it with a pump or the like installed outside. When the pump is installed, it may be installed on either the upstream side or the downstream side of the processing oil particle refining device A, but it is preferably installed on the upstream side. The size of the cylinder 1 and the number of the ceramics 4 and the turbulent flow generating means 2 installed as one block can be appropriately selected according to the type of processing oil passing through the cylinder 1 and the like. For example, when processing oil (cutting oil (JIS standard, W2-2)) used for small processing machines, tank capacity is 30L, pump discharge is 10L / min, it is in a cylinder with a diameter of 60mm and a length of 300mm. It is preferable to use a processing oil particle refining device provided with two ceramics and two turbulent flow generating means in series. Further, among the processing oils for small processing machines described above, especially in the case of processing oils used for deep hole processing, drawing processing, etc., one block of ceramics and turbulent flow generating means is provided in a cylinder having a diameter of 60 mm and a length of 300 mm. It is recommended to use a processing oil particle refining device comprising two of the above in series. Furthermore, when the tank capacity is 1200L and the pump discharge rate is 100L / min, it is a processing oil used for large processing machines, etc., and the ceramic and turbulent flow generating means are one block in a cylinder having a diameter of 150mm and a length of 800mm. Use a machined oil particle refining device that has one of the above, or have two ceramics and turbulent flow generating means in one block in series in a cylinder of 60 mm in diameter and 300 mm in length. A plurality of processing oil particle refining devices may be installed and used in parallel.
