도 2는 종래 기술에 따른 유리 섬유 리바를 인발하는 인발기를 도시한 도면이다. 이때, 인발기(17)는 우레탄 A90 재질로 주로 제조되며, 유리 섬유 리바(1)를 상하에서 가압한 상태에서 인발하게 되는데, 인발기(17)의 표면이 매끈하고 마찰계수가 낮아 유리 섬유 리바(1)가 인발기(17)에 대해 미끄러지면서 마모되는 단점이 있었다. 2 is a view showing a drawing machine for drawing a glass fiber rebar according to the prior art. At this time, the drawer 17 is mainly made of urethane A90 material, and is pulled out while the glass fiber rebar 1 is pressed up and down, and the surface of the drawer 17 is smooth and the friction coefficient is low. (1) There was a drawback of being worn while sliding against the drawer (17).

유리 섬유 리바의 인발 시에, 유리 섬유 리바가 미끄러지는 것을 방지할 수 있는 유리 섬유 리바 인발 블록을 제공하는 것을 목적으로 한다. It is an object of the present invention to provide a glass fiber rebar drawing block capable of preventing the glass fiber rebar from slipping during drawing of the glass fiber rebar.

본 발명은 유리 섬유 리바와 맞닿는 면에 슬립 방지 홈이 형성된 것을 특징으로 하는 유리 섬유 리바 인발 블록을 제공한다. The present invention provides a glass fiber rebar drawing block, characterized in that the slip preventing groove is formed on the surface in contact with the glass fiber rebar.

또한 본 발명의 다른 일 예로, PTFE로 제조되는 것을 특징으로 하는 유리 섬유 리바 인발 블록을 제공한다. In addition, as another example of the present invention, it provides a glass fiber rebar drawing block, characterized in that made of PTFE.

또한 본 발명의 다른 일 예로, 슬립 방지 홈은 유리 섬유 리바를 중심에 놓이도록 V자 형상을 가지는 것을 특징으로 하는 유리 섬유 리바 인발 블록을 제공한다. In addition, as another example of the present invention, the anti-slip groove provides a glass fiber rebar drawing block, characterized in that it has a V-shape to place the glass fiber rebar in the center.

본 발명이 제공하는 유리 섬유 리바 인발 블록은 유리 섬유 리바의 슬립을 방지하는 슬립 방지 구조를 구비함으로써, 유리 섬유 리바와 인발 블록 간의 슬립과 마모를 방지할 수 있다는 장점이 있다. The glass fiber rebar drawing block provided by the present invention has an advantage of preventing slip and abrasion between the glass fiber rebar and the drawing block by having a slip prevention structure for preventing slip of the glass fiber rebar.

이하, 도면을 참조하여 본 발명을 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the drawings.

도 3은 본 발명의 일 실시예에 따른 유리 섬유 리바 인발 블록의 사시도, 도 4는 본 발명의 일 실시예에 따른 유리 섬유 리바 인발 블록이 유리 섬유를 인발하는 모습을 도시한 도면이다. 3 is a perspective view of a glass fiber rebar drawing block according to an embodiment of the present invention, and FIG. 4 is a view showing a state in which the glass fiber rebar drawing block according to an embodiment of the present invention draws glass fibers.

본 발명의 일 실시예에 따른 유리 섬유 리바 인발 블록(100)은 PTFE로 제조된다. PTFE 재질은 종래의 우레탄 A90 재질에 비해 마찰계수가 낮아서 유리 섬유 리바(1)와 인발 블록(100) 사이에 슬립에 의해 마모가 발생하는 것을 줄일 수 있다.The glass fiber rebar drawing block 100 according to an embodiment of the present invention is made of PTFE. Since the PTFE material has a lower coefficient of friction than the conventional urethane A90 material, it is possible to reduce the occurrence of abrasion due to slip between the glass fiber rebar 1 and the drawing block 100.

또한 인발 블록(100)의 유리 섬유 리바(1)가 맞닿는 접촉면(110)에 도 3 및 도 4에 보인 바와 같이 인발 방향을 가로지르는 방향으로 복수 개의 홈(120) 구조를 구비할 수 있다. 홈(120)은 인발 블록(100)의 접촉면(110)이 가압될 때 유리 섬유 리바의 변형이 일어나도록 하여, 유리 섬유 리바(1)와 접촉면(110) 사이의 접촉성을 높일 수 있다. In addition, as shown in FIGS. 3 and 4, a plurality of grooves 120 structure may be provided in a direction transverse to the drawing direction on the contact surface 110 where the glass fiber rebar 1 of the drawing block 100 abuts. The groove 120 allows deformation of the glass fiber rebar when the contact surface 110 of the drawing block 100 is pressed, so that the contact between the glass fiber rebar 1 and the contact surface 110 can be improved.

또한, 인발 블록(100)과 접촉면(110)에 형성되는 홈(120)은 V자형인 것이 바람직하다. In addition, it is preferable that the groove 120 formed on the drawing block 100 and the contact surface 110 is V-shaped.
