Hereinafter, a metal hair line forming method using the metal hair line forming system according to the present invention will be described.

7 is a flowchart showing a method of forming a metal hair line according to the present embodiment.

First, the tip of the metal plate 10 supported on the metal plate feed roll 110 is clamped to the metal plate discharge roll 120. The tip of the abrasive mesh 30 wound on the abrasive mesh feed roll 310 is clamped to the abrasive mesh discharge roll 320).

The metal plate 10 is supported on a plurality of support rollers 130 in the form of a flat plate and the polishing mesh 30 is circumscribed by a plurality of pressure rollers 330 and a plurality of tension rollers 340, As shown in FIG.

Then, the rotation driving of the metal plate discharge roll 120 is started. The metal plate 10 is released from the metal plate feed roll 110 in accordance with the rotation driving of the metal plate discharge roll 120. At this time, the metal plate 10 is brought into rolling contact with the brush 210 and the luster formed on one surface thereof can be removed. In addition, the dust collecting unit 600 collects and discharges the metal powder, which may be generated while the luster of the surface of the metal plate 10 is removed, to the outside. (Step S11)

The glossy metal plate 10 is carried into the hair line forming unit 300. The rotation of the abrasive mesh discharge roll 320 is started. The grinding mesh 30 is released from the grinding mesh feed roll 310 as the grinding mesh discharge roll 320 rotates. At this time, the rotation speed of the metal plate discharge roll 120 and the rotation speed of the polishing mesh discharge roll 320 can be adjusted according to the shape of the hair line 11 to be formed on the metal plate 10. The separation distance between the plurality of pressure rollers 330 and the plurality of support rollers 130 is adjusted according to the precision of the hair line 11 to be formed on the metal plate 10. That is, the plurality of pressure rollers 330 can be lifted by the plurality of spacing adjusting units 350, respectively, and the spacing distance from the plurality of supporting rollers 130 can be adjusted. At this time, the operator can confirm the scale 303 and precisely adjust the positions of the plurality of pressure rollers 330. [

On the other hand, the abrasive mesh released from the abrasive mesh feed roll 310 in accordance with the rotation driving of the abrasive mesh discharge roll 320 is supported together by the first pressing roller 361 and the second pressing roller 362, And is pressed by the roller 363. Therefore, the abrasive mesh 30 can be conveyed while firmly holding the abrasive paper 31 and the support mesh 32 in a compressed state.

As the metal plate 10 and the abrasive mesh 30 are transported at different speeds, the hair line 11 can be formed on one side of the metal plate 10. At this time, in order to clean the abrasive powder, metal powder, etc., which may be generated in the process of forming the hair line 11 on the metal plate 10, the cleaning part 700 ejects the cleaning liquid. (Step S13)

Next, the metal plate 10 on which the hair line is formed is carried into the drying unit 400. The metal plate 10 is heated by the heater 420 in a clean environment inside the drying chamber 410 and the cleaning liquid remaining on the metal plate 10 can be evaporated.

Then, the dried metal plate 10 is carried into the bonded portion 500.
