[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention uses a pipe rod that rolls on an inclined line as a soft porous material that is impregnated with rust preventive oil. Rolling adhesion type pipe rod outer surface oil coating that passes over and adheres rust preventive oil to its outer surface Regarding the device.

[0002]

[Prior art]

  Prior to shipment of black tube products, rust-preventing oil is applied to the outer surface for rust protection. The external oiling device is disclosed in Japanese Utility Model Laid-Open No. 61-53011. There is a spray type. This external lubricator is a sprayer that is sprayed with rust preventive oil. Pass the pipe in the chamber in the axial direction and apply rust preventive oil to the outer surface. on the other hand In Japanese Utility Model Publication No. 2-17258, a soft porous material such as felt impregnated with a coating material is disclosed. Place the material on the rolling line of the pipe, and apply the paint to the outer surface of the pipe rolling on it. A rolling attachment type external coating device is disclosed. This device is not an oiling device By changing the paint to rust preventive oil, it can also be used as an oiling device.

[0003]

[Problems to be solved by the device]

  The conventional spray-type external oiling device has a complicated structure because it sprays rust preventive oil. It becomes expensive. Also, when dry solidification type rust preventive oil is used, the rust preventive oil is Widely adheres to the inside of the equipment and deteriorates the rust preventive oil consumption rate, and the inside and outside of the equipment becomes dirty, resulting in a bad working environment. And nozzles and pipes may become clogged. Uses slow-drying and non-drying rust preventive oil In this case, although clogging is unlikely to occur, other problems similarly occur.

[0004]   In that respect, the rolling adhesion type outer surface coating device does not require a complicated mechanism such as a sprayer, Moreover, the paint adheres only to the outer surface of the pipe material and does not scatter around. Therefore, the outer coating Even when used as an oil device, it is expected to exhibit excellent economic efficiency and maintainability. Shi However, the device disclosed in the above-mentioned publication is used to supply paint to the soft porous material. A part of the paint is dripped into the paint container and a mechanism for drawing paint by the so-called capillary phenomenon is adopted. is doing. In such a pumping mechanism, when antirust oil is used, its viscosity is high. The pumping volume is reduced. Further, the permeability of the soft porous material itself is not sufficient. Therefore, a sufficient amount of rust preventive oil is not attached to the outer surface of the pipe material, and the oil coating film becomes thin. Well Another problem is that it is difficult to control the film thickness when oils with different viscosities are used. Furthermore, Another problem is that rust preventive oil is used because the paint container is open upwards. In some cases, a solidified film may form on the oil surface in the container, which also prevents the stable supply of rust preventive oil. Cause harm.

[0005]   The purpose of the present invention is to stabilize a sufficient amount of rust-preventing oil on the pipe rod material, even though it is a rolling attachment type. An object of the present invention is to provide an outer surface oiling device which can be attached by applying.

[0006]

[Means for Solving the Problems]

  The outer surface oiling device of the present invention applies rust preventive oil to the outer surface of the pipe rod that rolls on the inclined line. The oiling part to be clothed is an external oiling device for pipe rods arranged in the rolling line, The oiling section includes an oil pan that is inclined along the rolling line and an oil pan above the oil pan. Circulate the rust preventive oil in the oil pan so that the rust preventive oil flows down from the upstream side to the downstream side. The oil circulation mechanism that allows it and the rust-preventive oil that circulates in the oil pan to stay in the oil pan The oil retaining member in the shape of a mesh laid on the oil pan, and the pipe rod rolls on the upper surface. And a soft porous material laid on the oil holding member.

[0007]   A plurality of the oiled parts are arranged in the rolling direction of the pipe rod material, and each of the oiled parts has a different type of protection. It can be configured to circulate rust oil.

[0008]

[Action]

  The lower surface of the soft porous material makes full contact with the rust preventive oil flowing down on the oil pan. It Moreover, the rust preventive oil is retained on the oil pan by the oil holding member. Obey Therefore, even if the viscosity of rust preventive oil is high or the viscosity changes, a sufficient amount of rust preventive oil can be used. Oil is stably impregnated into the soft porous material, and the thickness of the soft porous material is adjusted. And an oil coating film of appropriate thickness is uniformly formed on the outer peripheral surface of the tube rod rolling on it. . Moreover, since the rust preventive oil in the oil pan is covered with the soft porous material, a solidified film is formed on the oil surface. Does not occur and the solidified film does not hinder the supply.

[0009]   When multiple lubrication parts are arranged in the rolling direction of the pipe rod, except for one specific one, soft Make sure that the pipe rod does not come into contact with the soft porous material, such as by placing a crossover rod on top of the porous material. To do. As a result, the rust-preventing oil is applied to the outer surface of the pipe rod material only when it passes through the specific oiled part. Is applied. Similarly, another oiling portion can be used as appropriate.

[0010]

【Example】

  An embodiment of the present invention will be described below with reference to the drawings. Figure 1 shows the outside of the present invention FIG. 2 shows the overall structure of an example of the surface oiling device, showing a vertical side view of the oiling portion. 2 is a plan view, FIG. 3 is a side view, FIG. 4 is a view taken along the line AA of FIG. 2, and FIG. 5 is a line taken along the line BB of FIG. It is a perspective view.

[0011]   In the external oiling device, as shown in FIGS. 2 and 3, the pipe rod 100 rolls under its own weight. So that the rolling line gradually decreases from the upstream side to the downstream side. The rolling line is A stencil table 200 arranged in order from the upstream side to the downstream side thereof, and a three-stage oiling section 30 0, transfer table 400, drop-in rack 500, etc. Stencil table 200 and the oiling unit 300, between the oiling unit 300 and the transfer table 400, and the oiling unit Horizontally rotating pass arms 600 are installed between the 300. It Further, at the downstream end of each of the stencil base 200 and the transfer base 400, a lifting type Each of the stoppers 700 is attached.

[0012]   As shown in FIG. 1, each oiling portion 300 is located slightly below the rolling surface of the pipe rod 100. It has an oil pan 310 arranged. Oil pan 310 has the same angle as the rolling line It is inclined at a degree and extends horizontally in the horizontal direction perpendicular to the rolling direction of the pipe rod 100. Both ends are raised. On the bottom of the oil pan 310, expand The sheet-shaped soft porous material 330 is inserted through the liquid holding member 320 made of metal or the like. It is laid in two layers over the entire surface.

[0013]   The soft porous material 330 is, for example, a sponge or a span that can penetrate the rust preventive oil. Bond, felt, etc. can be used as appropriate, but it is a non-woven cloth made of polypropylene crimped fiber. For example, High Separe (trade name of Nissho Co., Ltd.) is especially desirable from the viewpoint of oil adsorption. Good In such a soft porous material 330, the proper oil viscosity changes depending on its porosity. The higher the viscosity, the higher the porosity. The thickness covers the surface of the tube rod material 100. In order to influence the film thickness of the oil coating film and increase the film thickness thereof, the soft porous material 330 Reduce the thickness. The thickness of the soft porous material 330 is adjusted by stacking the sheets. Is easy.

[0014]   An oil holding member 320 interposed between the soft porous material 330 and the oil pan 310. As for, expanded metal (JIS G3351), gold rope (JIS G35 51-355), wire lath (JIS A5504), in the thickness direction It is better to have a separate gap. Because it is a piece of steel plate punched like a mesh If each mesh is isolated, the rust preventive oil will only overflow on the oil holding member 320. Therefore, since the soft porous material 330 absorbs the rust preventive oil, The flow is hindered, and the oil content of the soft porous material 330 becomes uneven.

[0015]   An oil circulation mechanism 340 for circulating rust preventive oil is combined with the oil pan 310. Has been done. The oil circulation mechanism 340 is connected to the upstream side and the downstream side of the oil pan 310. It has a refueling gutter 341 and a recovery gutter 342 that are tied together. These are shown in FIG. 4 and FIG. As shown in, the oil pan 310 is continuous in the width direction. And the refueling gutter 34 The bottom of No. 1 is horizontal, and the bottom of the recovery gutter 342 is inclined with respect to the horizontal line. Times The downstream end of the gutter 342 is connected to the tank 343.

[0016]   The rust preventive oil is pumped from the tank 343 by, for example, a diaphragm type pump 345. It is raised and delivered to the main pipe 346. A large amount of rust preventive oil sent to the main pipe 346 The cheese joint 346a divides the flow into the branch pipe 347. Each branch pipe 347 A cock 347a is interposed, and the tip of the cock 347a is longitudinally spaced from the side plate of the refueling gutter 341. However, they are connected by a union 347b. The main pipe 346 and the branch pipe 347 are It is designed as a tube to facilitate the treatment of oil solidification troubles inside the tube. It The rust-preventing oil that has flowed into the refueling gutter 341 through each branch pipe 347 is stored in the oil pan 310. It flows down, flows into the recovery gutter 342, and returns to the tank 343.

[0017]   As the rust preventive oil, a dry one (for example, escort No. 100 made by Kansai Yushi), For pipe rod 100, such as those that do not dry (for example, VALVOLINE OIL) What is needed is used as appropriate. Although the dry type has a long storage period after oiling, It is difficult to remove the film. On the other hand, those that do not dry have a short storage period after application, but the oil film is removed. Easy to leave. Of these rust preventive oils, the dry ones usually contain organic solvents. .

[0018]   Further, the gas of the organic solvent vaporized from the rust preventive oil is exhausted to the oil pan 310. The exhaust mechanism 350 is combined. The exhaust mechanism 350 is provided with an oil gutter 341. The exhaust hood 351 is provided continuously on the upstream side. The exhaust hood 351 opens upward. It is in the shape of an inverted triangle that is released, and a plurality of them are in contact with the oil gutter 341 and arranged in the longitudinal direction. Has been done. Similarly, a plurality of exhaust hoods 352 are arranged on the downstream side of the collection gutter 342. Has been done. The exhaust hoods 351 and 352 are below the rolling surface of the pipe rod 100. Is located in. Each of the lower ends of the exhaust hoods 351 and 352 has an oil pan 310. To the main duct 353 extending in the width direction below the auxiliary duct 354 and And 356. Exhaust mechanism 350 from the rolling surface of tube rod 100 The lower part is designed to efficiently use the gas of the organic solvent used for rust preventive oil, which is heavier than air. This is to collect it. Inside the main duct 353 of each coating unit 300, a collecting pipe 357 is interposed. And is sucked by the fan 358 (FIG. 3).

[0019]   The three-stage oiling portions 300 are arranged in the rolling direction of the pipe rod 100. Each oiling part Inside the 300, different types of rust preventive oil are circulated. The three-stage oiling section 300 is It is selectively used according to the specifications of the tube rod material 100.

[0020]   In the outer surface oiling device, for example, the first-stage oiling portion 300 located on the most upstream side. When using, the pump 345 in the oil circulation mechanism 340 is operated, Anti-rust oil is supplied to the oil supply gutter 341. The rust preventive oil supplied into the oil supply gutter 341 is supplied with oil. It is evenly overflowed from the entire length of the gutter 341 and supplied onto the oil pan 310. to this As a result, the rust preventive oil flows down from the upstream side to the downstream side on the oil pan 310, The rust preventive oil is permeated into the soft porous material 330 above 10.

[0021]   At this time, the rust preventive oil on the oil pan 310 is laid on the bottom surface of the oil pan 310. It flows down while staying in the mesh of the mesh-shaped oil holding material 320 thus formed. And a lot of soft The entire lower surface of the porous material 330 comes into contact with the rust preventive oil accumulated in the mesh. Servant Therefore, even if the rust preventive oil has a high viscosity, the soft porous material 330 should have a sufficient amount of rust preventive oil. Penetrated. Further, the rust preventive oil on the oil pan 310 is constantly flowing, and The soft porous material 330 serves as a lid for the oil pan 310, and prevents the rust preventive oil on the lid. Prevent dryness. Therefore, no solidified film is formed on the rust preventive oil on the oil pan 310, and Therefore, the oil impregnation in the soft porous material 330 is promoted. Passing over the oil pan 310 The rust preventive oil is circulated to the refueling gutter 341 through the recovery gutter 342 and the tank 343.

[0022]   In the second and third oiling sections 300 that are not used, the oil circulation mechanism 340 The pump 345 is operated to circulate the rust preventive oil in the oil pan 310 to prevent the rust preventive oil from solidifying. Prevent from becoming. However, by placing an appropriate number of transfer rods on the soft porous material 330, The tube rod material 100 passing through 0 is prevented from coming into contact with the soft porous material 330.

[0023]   In such a state, the pipe rod 1 is transferred from the stencil table 200 to the first-stage oiling section 300. 00 is sequentially supplied. The pipe rod 100 supplied to the first-stage oiling section 300 is protected from Rolling on the soft porous material 320 sufficiently impregnated with rust oil, the rust-preventing oil is applied to the outer surface of the soft porous material 320. Is attached to the required thickness. The pipe rod 100 that has passed through the first-stage oiling section 300 is The second- and third-stage oiling portions 300 are passed in order by rolling on the transfer rod. . The pipe rod 100 that has passed the third-stage oiling section 300 is dropped through the transfer table 400. It enters the rack 500 and is carried out of the external oiling device.

[0024]   When switching the rust preventive oil, remove the passing rod from the oiling part 300 to be used next. Except for this, a passing rod is set in the oil coating section 300 that has been used up to now. This allows Switching of anti-rust oil is extremely easy.

[0025]

[Effect of device]

  The outer surface oiling device for a pipe rod according to the present invention pours rust preventive oil on the oil pan and By laying a soft porous material on top of it through a mesh-shaped oil holding member, The soft porous material can be impregnated with a sufficient amount of lubricating oil without being affected by the viscosity of . Also, since the rust preventive oil on the oil pan flows and is covered with the soft porous material, , There is no danger of a solidified film forming on the rust preventive oil, and the rust preventive oil is immersed in the soft porous material. The transparency is stable. Therefore, the necessary and sufficient rust preventive oil is applied to the pipe rod material.

[0026]   If multiple oil coating parts are arranged in the rolling direction of the tube rod material, multiple types of rust prevention on the same line Oil can be selectively used, and the type of oil can be easily switched.
