Description

  The present invention relates to an improvement in a surface polishing apparatus capable of effectively removing dirt on the surface of a wire.

  The present inventors, as an intermediate product in the middle of processing, feed the wire in one direction by inserting the wire into a pass line that penetrates the main body of the wire as a surface polishing device for the surface of the wire with dirt such as lubricating oil. At the introduction hole part of the pass line, a jet jet of fluid such as cleaning liquid such as water, warm water, trichlene and detergent or abrasive liquid mixed with abrasive is sprayed in the feed direction of the wire. At the same time as the surface treatment is performed, the introduction hole is made negative pressure by the flow of the jet jet, the outside air is introduced into the main body of the apparatus through the introduction hole, and the introduction hole is sealed. The jet jet of the fluid is blown in the direction opposite to the feed direction, and the surface treatment of the wire is performed again. At the same time, the discharge hole is made negative by the flow of the jet jet in the reverse direction, and the outside air is caused to flow into the apparatus body from the lead hole. Seal the outlet hole After rapidly expanding the jet stream in the apparatus main body, it has proposed a surface polishing apparatus capable of effectively removing dirt on the surface of the wire by deriving the fluid out of the apparatus main body (Patent Document 1).

JP-A-61-204386

  This conventional device uses water, warm water or a cleaning liquid such as trichlene or detergent as a fluid, and cleans the surface of the wire by washing away the oil stain on the surface of the wire with a jet jet or blowing off the water after the last water wash. However, the surface of the wire has various stains, such as a scale after heat treatment, a solid lubricant after drawing a wire drawing die, and the like that cannot be removed by the above cleaning liquid. In this case, as described above, the surface of the wire is polished and removed with the polishing liquid mixed with the abrasive grains. In this conventional apparatus, the abrasive grains are mixed into the fluid (polishing liquid) supply path connected to the pass line. In addition, since the polishing liquid is directly passed, there is a problem that the jet flow passage gap that requires fine adjustment of the gap is abruptly worn and the durability is poor.

  The present invention has been made in view of the conventional example, and grinds dirt that cannot be removed with a cleaning liquid, such as a scale after heat treatment adhering to the surface of a wire and an adhering solid lubricant after drawing a wire drawing die, at high speed over a long period of time. It is an object of the present invention to provide a surface polishing apparatus that can be removed.

An inlet side polishing liquid inflow hole 7a for supplying the polishing liquid H to the pass line C is provided downstream of the jet flow passage gap 6a, and an outlet for supplying the polishing liquid H to the pass line C upstream of the jet flow passage gap 6b. Side polishing liquid inflow hole 7b is provided,
Between the inlet side polishing liquid inflow hole 7a and the outlet side polishing liquid inflow hole 7b, there is provided a polishing liquid discharge portion 8 for discharging the polishing liquid H that has passed through the pass line C,
Between the inlet side polishing liquid inflow hole 7a and the polishing liquid discharge part 8 and between the outlet side polishing liquid inflow hole 7b and the polishing liquid discharge part 8, there is a turbulent flow formation space R opened so as to surround the pass line C. It is formed.

In the wire surface polishing apparatus A of claim 1,
The inlet side polishing liquid inflow hole 7a and the outlet side polishing liquid inflow hole 7b are formed so as to communicate with the expansion spaces 4a and 4b at the outlet portions of the jet flow passage gap 6a and the jet flow passage gap 6b. .

  A turbulent flow forming space opened so as to surround the pass line C between the inlet side polishing liquid inflow hole 7a and the polishing liquid discharge part 8 and between the outlet side polishing liquid inflow hole 7b and the polishing liquid discharge part 8. Since R is formed, the polishing liquid H flowing in the pass line C toward the polishing liquid discharge portion 8 rapidly expands in the turbulent flow formation space R in the middle of the flow, and causes a more severe shear turbulence. The abrasive K is violently collided with the surface of the wire W on which this shearing turbulent flow is running, and scales, solid lubricants and other dirt and deposits that have been difficult to remove are removed. As a result, dirt and deposits that could not be removed by the conventional apparatus can be reliably removed from the surface of the wire W.

A gap S through which H flows out is provided. Then, a female screw hole for the fixing screw 9 is threadedly provided on the outer periphery of both ends of the polishing liquid discharge portion 8 at an equal angle.

  The polishing liquid circulation container 50 has a hollow rectangular parallelepiped shape, and a filter mounting opening 51 is formed on at least one surface. A cover member 55 having a hollow inside is mounted so as to cover the portion 51, and the polishing liquid circulation container 50 is mounted on the filter mounting opening 51. The filtrate L that has passed through the filter 52 is collected and allowed to flow into an abrasive precipitation tank 70 described later. Mounting holes 53a and 53b for the inlet / outlet side liquid supply portions 1a and 1b are formed in both end faces of the polishing liquid circulation container 50.

  The filter 52 is formed by laminating thin plate-like filter members 52 a with a slit interval 52 s narrower than the abrasive K particles, and is attached so as to cover the entire surface of the filter mounting opening 51. As can be seen from FIG. 5, the cross section of the filter member 52a is wide on the inner surface (inflow) side of the polishing liquid circulation container 50 and becomes narrower toward the cover member 55 side which is the filtrate outflow side. Yes.

  The abrasive sediment tank 70 is provided with an overflow weir (this is referred to as an overflow weir 71) in the center, and the filtrate L from the cover member 55 flows into the container portion 70a on the inlet side. . A circulation pump P is installed in the container portion 70b on the outlet side, and the outlet of the circulation pump P is branched and connected to the liquid supply nozzles 18a and 18b of the inlet / outlet side liquid supply portions 1a and 1b, and the filtrate L is supplied.

Are screwed into female screw portions 22a and 22b formed in the opening on the insertion end side. The opposite end portions of the turbulent flow forming member storage cylinders 3a and 3b on the inlet / outlet side are spaced apart from each other, and a polishing liquid discharge portion 8 is mounted so as to surround the opposite end portions, and is fixed. It is fixed with screws 9. Then, the polishing liquid H press-fitted from the inlet / outlet side liquid supply parts 1a and 1b flows out from the opposite end part and collides in the polishing liquid discharge part 8 to cause intense turbulent flow. The liquid flows out from a gap S provided between the opposing ends of the parts 1a and 1b and the polishing liquid discharge part 8 surrounding the ends. The space in the polishing liquid discharge part 8 that causes the intense turbulent flow is defined as a turbulent flow forming space R8. Further, the turbulent flow generating space in the turbulent flow generating member housing cylinders 3a and 3b on the inlet / outlet side is a bullet-shaped turbulent flow forming space in which a turbulent flow forming tapered hole 5a1 and a round hole 5a2 are integrated. R is formed around the through-hole of the turbulent flow generation member 5a constituting a part of the pass line C at one or more places. In the illustrated embodiment, there are three turbulent flow forming member storage cylinders 3a and 3b on the inlet / outlet side.

  The abrasive K includes, for example, a steel wire or a granular material obtained by cutting a stainless steel wire, a glass grain, an abrasive grain, and the like, and is selected depending on the steel type and application of the wire W to be polished. As the liquid L, a suitable liquid such as a cleaning liquid or cleaning oil such as water, warm water, acetone or trichlene is used. In the case of water or hot water, it is environmentally friendly and easy post-treatment is preferable.

  Next, the operation of the device A of the present invention will be described. When an appropriate amount of the selected abrasive K is put in the polishing liquid circulation container 50 and the circulation pump P is started, the liquid L is sucked from the container part 70b on the outlet side of the abrasive precipitation tank 70 via the refiltration filter 80, The liquid supply nozzles 18a and 18b are press-fitted and supplied. The liquid L press-fitted and supplied to both liquid supply nozzles 18a and 18b passes through the turbulent flow forming member storage cylinders 3a and 3b on the inlet / outlet side from the liquid supply portions 1a and 1b on the inlet / outlet side, and the turbulent flow forming member storage cylinders. The polishing material K flows into the polishing liquid circulation container 50 from the gap S between 3a and 3b and the polishing liquid discharge part 8, and the polishing material K is stirred to obtain a polishing liquid H in which the polishing material K is uniformly dispersed.

  In this state, the wire W is fed through the pass line C in one direction. Since the liquid L continues to be press-fitted and supplied to both the liquid supply nozzles 18a and 18b by the circulation pump P, the liquid L that has passed through both the liquid supply nozzles 18a and 18b enters the liquid supply spaces 19a and 19b, and then the liquid. The high-pressure liquid L in the supply spaces 19a and 19b is rapidly ejected from the inlet / outlet jet flow passage gaps 6a and 6b toward the polishing liquid discharge portion 8 at an angle in the pass line C. In other words, the liquid is ejected in the feeding direction of the wire W on the inlet side liquid supply unit 1a side, and in the opposite direction to the feeding direction of the wire W in the outlet side liquid supply unit 1b. Each of the high-speed liquid L ejected rapidly expands in the expansion spaces 4a and 4b following the inlet / outlet side jet flow passage gaps 6a and 6b, and the portions 4a and 4b become negative pressure, thereby expanding the expansion spaces 4a and 4b. The inlet C1 and outlet C2 side of the pass line C connected to is made negative pressure, and outside air is sucked into the pass line C side. Thereby, leakage of the liquid L from the inlet C1 and the outlet C2 is prevented.

  Similarly, the expansion spaces 4a and 4b having negative pressure cause the polishing liquid H to be sucked into the expansion spaces 4a and 4b from the polishing liquid inflow holes 7a and 7b connected to the expansion spaces 4a and 4b. While entraining H, the jet flow of the liquid L flows into the turbulent flow generating members 5a and 5b from the expansion spaces 4a and 4b at a high speed. As shown in FIGS. 2 and 3, the needle portions 13a and 13b at the tips of the needle valves 2a and 2b protrude into the expansion spaces 4a and 4b and are polished toward the tip portions of the needle portions 13a and 13b. If the liquid inflow holes 7a and 7b are opened, the liquid L ejected from the jet flow passage gaps 6a and 6b flows at high speed along the needle portions 13a and 13b, and effectively entrains the polishing liquid H. The polishing liquid H flows in the forward direction in the turbulent flow generation member 5a on the inlet side with respect to the feeding direction of the wire W, but flows in the reverse direction in the turbulent flow generation member 5b on the outlet side.

  The polishing liquid H flowing into the turbulent flow generating members 5a and 5b is pressed into the narrow pass line C of the turbulent flow generating member 5a from the expansion spaces 4a and 4b to increase the flow velocity, and the turbulent flow forming tapered holes 5a1 and the round holes 5a2. In addition, the turbulent flow forming space R formed by the turbulent flow forming tapered hole 5b1 and the round hole 5b2 rapidly expands to generate a shearing turbulent flow, and the abrasive K is rubbed vigorously on the surface of the wire W. This is repeated several times and finally discharged into the polishing liquid discharge section 8. In addition, since the exit side to the turbulent flow formation space R with respect to the flow of the polishing liquid H is configured by the round holes 5a2 and 5b2, the polishing liquid H rapidly expands as soon as it exits the narrow pass line C, Since the inlet side to the turbulent flow forming space R is formed by the tapered turbulent flow forming tapered holes 5a1 and 5b1, it smoothly flows into the narrow pass line C.

  When the polishing liquid H flows into the polishing liquid discharge part 8 from both sides after passing through the thin pass line C, the inside of the polishing liquid discharge part 8 is a much wider space than the thin pass line C of the turbulent flow generation member 5a. The polishing liquid H rapidly expands while expanding, and flows out into the polishing liquid circulation container 50 through the gap S between the polishing liquid discharge portion 8 and the inlet / outlet side turbulent flow forming member storage cylinders 3a and 3b. In this polishing liquid H, dirt such as metal powder and oxide film powder scraped from the surface of the wire W is also mixed.

  Here, the difference between the inlet side and the outlet side is that the polishing liquid H flowing through the turbulent flow generation member 5a on the inlet side is in the same direction as the feeding direction of the wire W, so the flow rate of the polishing liquid H is accelerated. A more intense shear turbulence is formed in the turbulent flow formation space R, and most of the dirt is scraped off. On the other hand, since the polishing liquid H flowing through the turbulent flow generation member 5b on the outlet side is in the direction opposite to the feeding direction of the wire W, the flow rate of the polishing liquid H is reduced, but dirt that cannot be removed in the forward direction is disturbed. All of the stubborn dirt scraped off in the flow forming space R and attached to or generated on the wire W is removed.

  A part of the polishing liquid H that has flowed into the polishing liquid circulation container 50 is supplied again to the pass line C from the inlet / outlet side polishing liquid inflow holes 7a and 7b as described above, and the surface of the wire W fed is supplied. Grind. The remaining polishing liquid H is filtered by the filter 52 and sent to the liquid circulation path J. The liquid circulation path J is composed of an abrasive precipitation tank 70, a fine particle refiltration filter 80, a circulation pump P, and a group of pipes that connect these and the liquid supply nozzles 18a and 18b of the apparatus main body B.

  As described above, only the filtrate L filtered by the filter 52 flows into the container portion 70 a on the inlet side of the abrasive precipitation tank 70. As described above, the abrasive K is made by cutting a steel wire or stainless steel wire into a granule, glass particles, abrasive grains, or the like, and gradually becomes worn or broken during use. The finely divided abrasive K passes through the slit interval 52s (or slit hole) of the filter 52 and flows into the inlet side container portion 70a. However, since the finely divided abrasive K is heavy, the inlet side container portion 70a is heavy. It is only the filtrate L that does not contain the abrasive K that precipitates at the bottom of the steel and exceeds the overflow weir 71. Then, the pressure is supplied to the abrasive material circulation container 50 by the circulation pump P as described above.

  As described above, the jet flow passage gaps 6a and 6b through which only the liquid L passes are independently provided outside the polishing liquid inflow holes 7a and 7b for supplying the polishing liquid H, thereby preventing the wear of the apparatus main body B. Can be operated for a long period of time, and by forming the turbulent flow formation space R around the pass line C, it is possible to cause shear turbulence effective for surface polishing. Dirt and deposits that could not be removed can be reliably removed from the surface of the wire W.
