Description

Wire oil coating device {Device for oiling wires}

The present invention relates to a device for applying process oil to surfaces such as steel reinforcing steel cords and steel cord steel wires, and more particularly, cylindrical oil filled with atomized process oil on a moving path of wires drawn or drawn. The present invention relates to a wire oil applicator provided with an applicator to enable uniform application of oil between movements of the wire.

In general, steel cords used for reinforcing tires of vehicles are required to have excellent adhesion with rubber. For this purpose, the surface of steel wires constituting steel cords is plated with brass and process oil is applied to the surfaces. Coating.

As described above, when the process oil is applied to the steel cord element wire, it is known that the adhesive force is improved under all conditions such as hot air aging, heat aging, humidity, as well as initial adhesive force, before application.

In addition, if the stranded wire is coated with process oil on the wire (filament) during the manufacture of steel cords, the wire will give lubricity to the friction part when the wire passes through various rollers, wheels, and dies. In addition, it serves to minimize the supply tension by reducing the frictional resistance of the individual wires to prevent the disconnection in the twisted pair process.

The process oil coating process on the wire surface is carried out at the exit of the finishing die in the case of the wire drawing process for the element wire, and in the case of the process of producing the multi-strand strand wire, the oil is any one of the lower, middle or upper edge. Or oil applied to all of these smokes, where oil is applied to the oil-filled oil bath to allow the wire to pass through in an oil-filled oil bath during the deposition or movement of the wire. It is carried out by two types of contact types, in which the oil is in contact with the gauze or sponge which is absorbed so that the oil contained in the gauze and the like sticks to the surface of the wire.

On the other hand, the oil applied to the surface of the wire in the drawing process is dried by the sensible heat of the wire generated in the drawing process does not require a separate drying device, but in the case of stranded wire separate for drying the applied oil It requires a drying device.

1 is a schematic diagram of an oil coating process in a drawing process of a wire for a conventional steel cord, based on which, a conventional oil coating process and problems will be described.

First, the base material element wire 2 drawn out from the supply reel 1 is moved to the drawing machine 4 filled with wet lubricating oil through the guide roller 3.

In the drawing machine 4, a capstan 5 composed of a pair of multi-stage concentric structures is installed, and the element wire 2 introduced into the drawing machine 4 passes through each end of the capstan 5 sequentially. It moves out of (4). At this time, the element wire (2) is the original in the process of passing through a plurality of drawing die (5a) installed on the path passing through each end of the capstan (5) and the finishing die (6b) mounted on the exit side of the drawing machine (4) Freshness is achieved with a gradual decrease in diameter from the diameter.

Next, the element wire 2 exiting the drawing machine 4 is guided to two take-out capstans 7a and 7b and finally directed to the take-up reel 8, in which process oil is placed on the elementary passage path between both capstans. The coating device 9 and the oil coating amount adjusting device 10 are provided to be configured to apply the process oil to the fresh wire.

At this time, the oil coating device 9 is composed of a gauze or sponge dropping the process oil from the vertical upper portion of the oil coating device 9 is composed of a deposition type so that the oil is applied to the surface of the element wire (2) that moves while contacting or oil therein It takes any form of immersion type which allows the wire to pass through in this state filled oil tank.

On the other hand, the oil coating amount adjusting device 10 installed on the wire passing path at the rear end of the oil coating device 9 is called a 'Shibori' device, the through-hole of the size that passes through the outer peripheral surface of the wire to form a contact state therein This is provided so that the oil is excessively applied to the surface of the element wire is made.

By the way, the conventional oil coating amount control device 10 is abrasion occurs in the inner peripheral surface of the wire passing through the passage of time, according to the tunnel phenomenon occurs, the element wire (2) of the site where the oil is excessively applied Even if it passes, there is a problem that can not remove it.

In other words, the conventional oil application amount adjusting device has a difficulty in constantly managing the application amount of the process oil applied to the surface of the element wire.

If the oil coating amount on the surface of the wire is not properly managed as described above, the drying effect is lowered, and there is a high possibility of secondary contamination in the subsequent twisted wire process, and there is a fear of discoloration in case of poor drying. Rather high side effects can be caused by process oils.

The present invention has been made to solve the above-mentioned problems which are pointed out in the conventional immersion or contact process oil coating device, and the coating amount adjusting device is made by atomizing the process oil to make it contactlessly on the surface of the wire. It is an object of the present invention to provide an oil coating device for a wire that can maintain a predetermined coating amount without the need.

Another object of the present invention is to adjust the amount of sprayed from the atomizer nozzle injector according to the wire diameter or structure of the oil coated wire, so that an appropriate amount of oil can be applied and a small amount of oil is uniformly applied to the wire surface. It is to provide an oil coating device of the wire to enhance the drying effect by.

The screw guide 24 and the atomization oil circulation pipe 25 which both ends are located in the wire inlet 21 side and the outlet 22 side of the main body housing 20, and rotates spirally in the direction and form a closed loop 25 )

As shown in FIG. 2, the main body housing 20 is mounted to be opened and closed by hinge rotation with respect to the lower housing 20a and the lower housing, and the upper housing 20b includes a upper housing 20b provided with a handle 20c. do.

Inside the body housing 20, there is embedded a screw guide 24 made of a spiral plate to induce the flow of the atomized oil (GO) introduced therein, as shown in Figure 3, the screw guide as shown It may be formed integrally with the length which covers the full length of the main body housing 20, and may be comprised in the form which attaches many plate-shaped partitions to the inner peripheral surface of the main body housing 20. As shown in FIG.

At this time, the screw guide 24 is between the wire inlet, outlet 21, 22 formed in the central portion on both sides of the body housing 20 to facilitate the movement of the wire (W) in the body housing 20 It shall be designed so as not to block the straight path.

The atomizing nozzle injector 23 is installed on the atomization oil circulation pipe 25 connected to the bottom surface of the lower housing 20a near the wire outlet 22 of the main body housing 20 and circulated through the atomization oil circulation pipe. The atomized oil injected from the injector together with the oil GO is supplied into the body housing 20.

A process oil coating layer is formed on the surface of the wire exiting the main housing 20 by the circulation of the atomizing oil GO and the movement of the wire W through the main housing 20, and the coating layer is thin. As it is formed uniformly, it does not require a separate oil coating amount adjusting device and drying device.

The adherend wire in this embodiment may be any kind of wire rod to which process oil is applied, including rubber reinforcing steel cords, steel cord strands (filaments), steel cord strands, and the like.

As described above, the process oil applicator of the present invention uniformly applies non-contact atomized oil to the surface of the wire, and does not require a separate device for controlling the amount of oil applied as well as the quality characteristics of the wire product. There is an effect to improve.

In addition, the present invention can easily adjust the amount of oil applied to the surface according to the wire diameter or type of the wire, there is an advantage that the drying effect is also excellent because the amount of the coating itself is small.
