Description

Wire washing device {STEEL WIRE WASHING DEVICE}

The present invention relates to a wire cleaning device, and more particularly, to a wire cleaning device capable of effectively cleaning phosphate applied to the surface of a wire by using cleaning oil.

Bolts, nuts, screws and automobile parts are manufactured through a cold forging process using coiled wire.

In order to manufacture bolts, nuts, screws, and automobile parts, a method of cutting steel wire to a certain length and then forming it through cold forging is used. At this time, a process of washing and removing phosphate on the surface of the wire is required before forming the wire by cold forging.

Phosphate is applied to the surface of the wire for the two purposes of reducing frictional heat and preventing the wire from corroding by blocking contact with air when drawing a wire with a thick diameter in order to manufacture the wire with a desired diameter.

In order to manufacture bolts using iron wire, it is necessary to cleanly clean the phosphate applied on the surface of the iron wire.

Conventionally, cold oil or washing oil has been used to remove phosphate, but foreign substances have not been completely removed. If the foreign matter and phosphate are not removed in this way, the foreign matter is caught in several molds during the cold forging process, and the product specifications are not constant, resulting in defects and material loss.

As shown enlarged in FIG. 5, the washing oil O is supplied to the washing inlet pipe 415 of the washing oil supply casing 410, and the washing oil (O) is supplied to the washing inlet hole 441 of the washing inlet shaft 440. O) is moved. Then, the washing oil (O) is discharged to the washing oil discharge hole 425 of the inlet cap coupling plate 420 through the washing oil moving path 437 of the washing oil movable shaft 430.

The washing oil O discharged through the washing oil discharge hole 425 is moved to the washing flow groove 312 of the wire inlet cap 310 coupled to face the inlet cap coupling plate 420, and the washing fluid flow groove It moves along the washing oil distribution hole 313 of 312.

The washing oil O is moved to a plurality of washing oil injection pipes 320 communicating with the washing oil distribution hole 313, and through a plurality of washing oil injection nozzles 321 formed on the path of the washing oil injection pipe 320. sprayed out

Since the wire cleaning unit 300 rotates, the washing oil O is evenly sprayed on the surface of the wire A, and in this process, the phosphate on the surface of the wire A is washed and peeled off.

The waste washing oil (O') in contact with the surface of the iron wire (A) is moved to the lower part of the washing casing (100) and is discharged through the waste washing oil discharge hole (331).

The iron wire (A), which has been ironed, is moved along the inside of the wire guide pipe 341 of the wire discharge cap 340 and the guide plate insertion tube 341a, and the wire discharge provided in the wire outlet 130 of the casing body 110 is discharged. It is discharged to the outside through the guide tube 131.

The iron wire A' discharged through the iron wire discharge port 130 is discharged in a state in which the phosphate layer on the surface is cleanly washed.

On the other hand, Figure 6 is an exemplary view showing a modified example of the wire cleaning device (1a) of the present invention. As shown, the iron wire cleaning device 1a according to the modified example further includes an air wire cleaning unit 800 for secondarily washing the iron wire A' that has been cleaned in the wire cleaning unit 300 with washing oil and air.

The air wire cleaning unit 800 secondarily cleans the wire (A′) introduced after cleaning in the wire cleaning unit 300 with the cleaning oil supplied to the washing oil supply pipe 810, and supplies it to the air supply pipe 820. After removing the washing oil on the surface with high-pressure air, it can be discharged to the outside.

7 is a diagram showing the configuration of a wire cleaning device 1b of another modified example of the present invention.

As shown, the wire cleaning apparatus 1b of another modification may further include a casing cover 700 for opening and closing the upper portion of the washing casing 100. The casing cover 700 is coupled to the upper part of the washing casing 100 to be openable and openable, and covers the upper part of the washing casing 100 during the cleaning process of the iron wire to block foreign substances from entering the inside.

In addition, a cleaning unit cover 800 covering the mesh cover 330 of the wire cleaning unit 300 may be provided inside the cleaning casing 100 . The washing unit cover 800 has a semicircular cross section, and both ends are fixed to the inner wall surface of the washing casing 100 to cover the top of the mesh cover 330 . The cleaning unit cover 800 is disposed to be spaced apart from the mesh cover 330 and does not interfere with the rotation of the wire cleaning unit 300.

The washing unit cover 800 prevents the washing oil O discharged to the outside through the mesh cover 330 from escaping out of the washing casing 100 .

As described above, the wire cleaning device according to the present invention supplies washing oil to the continuously moving iron wire and cleans the phosphate.

In addition, since the washing oil is evenly sprayed to the surface of the washing oil after distributing it to a plurality of washing oil injection pipes, the entire area of the wire can be washed uniformly.

Thereby, there is an advantage in that the phosphate on the surface of the continuously supplied iron wire can be effectively washed.

The embodiment of the wire cleaning device of the present invention described above is only exemplary, and those having ordinary knowledge in the art to which the present invention belongs are well aware that various modifications and other equivalent embodiments are possible therefrom. You will be able to. Therefore, it will be well understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. It is also to be understood that the present invention includes all modifications, equivalents and alternatives within the spirit and scope of the present invention as defined by the appended claims.
