Description

전단기 안전보호대{Guard of Shearing Machine}Shearing Machine Safety Guard {Guard of Shearing Machine}

본 발명은 소재를 절단하는데 사용되는 전단기에 설치되는 전단기 안전보호대에 관한 것으로서, 특히 소재 절단 작업시 작업자의 신체의 일부가 전단날(Blade)이나 클램프(Clamp)에 들어가지 않도록 안전성을 확보하고 최대한 근접하여 절단작업을 하기 위한 전단기 안전보호대에 관한 것이다.    The present invention relates to a shear protector which is installed in a shear used to cut a material, and particularly ensures safety so that a part of a worker's body does not enter a blade or a clamp during a material cutting operation. Shear safety guard for cutting work as close as possible.

도 1은 소재를 절단하는데 사용되는 일반적인 전단기(100)를 도시한 사시도로서, 도 1에 도시된 바와 같이, 메인모터의 회전운동을 유압이나 기계적 동력전달장치를 통해 전단날(Blade)(150)에 전달하여 소재(140)를 전단하게 된다.     1 is a perspective view showing a general shearing machine 100 used to cut a material, as shown in Figure 1, the blade 150 through the rotational motion of the main motor through a hydraulic or mechanical power transmission device ) To shear the material 140.

이때, 클램프(120)가 작업대(130)에 투입된 소재(140)를 지지하게 되고 그 상태에서 전단날(Blade)(150)에 의해 전단이 이루어 진다. At this time, the clamp 120 supports the material 140 injected into the workbench 130 and shearing is performed by the shear blade 150 in that state.

그런데 전단기(100)에 소재(140)을 투입할 때, 작업자의 부주의로 클램프(Clamp)(120)나 전단날(Blade)(150)에 손가락이 절단되거나 압착되는 경우가 종 종 발생하게 된다. However, when the material 140 is injected into the shearing machine 100, a finger is cut or crimped on the clamp 120 or the blade 150 inadvertently by the operator. .

도 2는 이러한 안전사고를 방지하기 위해 실용신안등록번호 20-0260166 (2001.12.26)에 나타나 있는 대표적인 종래의 전단기 안전보호대를 나타낸 사시도로서, (a)는 망형식의 전단기 안전보호대를 나타낸 사시도 이고, (b)는 요철형 방호울를 나타낸 사시도이다.  Figure 2 is a perspective view showing a typical conventional shearing safety guard shown in Utility Model Registration No. 20-0260166 (December 26, 2001) to prevent such a safety accident, (a) is a shear type safety guard of the network type (B) is a perspective view which shows an uneven | corrugated protection enclosure.

(a)의 경우, 도시된 바와 같이 작업대의 작업자 쪽에 전단날(Blade)(150)과 클램프(Clamp)(120)에 평행하게 일직선상으로 금속이나 그 밖의 소재로 망(160)을 만들어 작업자의 신체 일부가 들어가지 않게 전단기 몸체에 고정하여 설치하였다. In the case of (a), the mesh 160 is made of metal or other material in a straight line in parallel with the shear blade 150 and the clamp 120 on the operator's side of the work bench as shown in FIG. The body part was fixed to the shearing body so that it was not installed.

상기 망(160)은 정확하게 설치시 방호가 확실한 장점이 있는 반면 가드에 의해 시야가 완전하게 확보되지 못하여 소재의 전단선에 정확히 맞추기 어렵게 하거나 재료를 정확하게 넣기 위해 작업자의 손을 전단선 가까이 접근시키기 곤란하게 하는 등 정교한 작업에 불편한 단점이 있었다.  While the mesh 160 has a clear protection when installed correctly, the field of vision is not completely secured by the guard, making it difficult to accurately fit the shear line of the material or difficult to approach the worker's hand near the shear line to accurately insert the material. There was an inconvenient drawback to such sophisticated work.

(b)의 경우, 도시된 바와 같이 다수의 클램프(Clamp)사이에 위치하는 방호울(161)의 일부분을 전단기 내부로 들어가도록 요부로 형성한 것으로, 철판의 절단시 클램프(Clamp) 또는 전단날(Blade)에 작업자의 손이 압착되거나 절단되지 않는 장점이 있으나, 요철형 방호울(161)이 고정되어 있지 않아 작업시 움직여 버리는 단점이 있어 작업능률을 저해하는 요소로 작용하였다. In the case of (b), a portion of the protective shield 161 positioned between the plurality of clamps is formed as a recess to enter the shearing machine as shown in the figure. There is an advantage that the hand of the worker is not pressed or cut on the blade (Blade), but the concave-convex anti-foil 161 is not fixed, so there is a disadvantage that it moves during work, which acted as a factor that hinders work efficiency.

상기 문제점을 해결하기 위해, 본 발명은 소재를 절단하는데 사용되는 전단기의 클램프(Clamp) 지지대에 고정설치되어, 작업자의 안전사고 방지 및 작업능률 향상을 이룰 수 있는 전단기 안전보호대를 제공하고자 하는 것을 목적으로 한다.In order to solve the above problems, the present invention is fixed to the clamp (Clamp) support of the shear used to cut the material, to provide a shear safety guard that can achieve a safety accident prevention and work efficiency of the operator For the purpose of
