Description

곡면 용접용 접지장치{Grounding Apparatus for Electric Welding on Curved Surface}Grounding Apparatus for Electric Welding on Curved Surface

본 발명은 곡면 용접용 접지장치에 관한 것으로, 더욱 상세하게는 용접대상물에 접지케이블을 연결하기 위하여 사용되되 원통 형상 또는 곡면 형상으로 형성된 용접대상물에 안정적으로 고정됨과 아울러 간단하게 탈착 가능하여 사용이 편리하며 접지부위에서 아크가 발생하는 것을 방지하여 안전성이 향상되도록 한 곡면 용접용 접지장치에 관한 것이다.The present invention relates to a grounding device for curved welding, and more particularly, it is used to connect a grounding cable to a welding object, and is stably fixed to a welding object formed in a cylindrical or curved shape, and is easily detachable, so it is convenient to use And it relates to a grounding device for curved surface welding to improve safety by preventing arcing at the grounding part.

일반적으로, 용접이란 2개 이상의 물체나 재료의 접합부분을 접합시키는 방법으로, 융접과 압접 및 납땜으로 구분된다. 융접은 접합하고자 하는 모재의 접합부를 국부적으로 가열 용융시킨 상태에서 용가재인 용접봉을 녹여 첨가함으로써 부착하는 방식으로, 용접이라 함은 대부분 융접을 의미한다. 압접은 접합부를 적당한 온도로 가열 또는 냉각한후 기계적 압력을 가하여 접합하는 방식으로 가압용접이라 한다. 그리고 납땜은 접합할 모재보다 융점이 낮은 비철금속 등을 용가재로 사용하는 접합방식을 의미한다.In general, welding is a method of joining a joint portion of two or more objects or materials, and is divided into fusion welding, pressure welding, and soldering. Fusion welding is a method of attaching by melting and adding a welding rod, which is a filler metal, in a state where the joint of the base material to be joined is locally heated and melted. Pressure welding is a method of joining by applying mechanical pressure after heating or cooling the joint to an appropriate temperature. And soldering refers to a joining method in which a non-ferrous metal having a lower melting point than the base material to be joined is used as a filler material.

여기서, 융접은 열원의 종류에 따라 전기용접과 가스용접, 전자빔 용접 및 플라즈마 용접 등으로 구분되며, 전기용접은 아크방전에서 생기는 높은 온도를 이용하여 접합함에 따라 아크용접이라고도 한다.Here, fusion welding is divided into electric welding, gas welding, electron beam welding, plasma welding, etc. depending on the type of heat source, and electric welding is also called arc welding as it joins using a high temperature generated by arc discharge.

상기한 전기용접을 위해서는 일정 위치에 용접기를 설치하고, 용접기에 구비된 (-)극성의 접지케이블과 (+)극성의 용접케이블을 각각 인출한 후, 접지케이블의 끝단에 연결된 접지장치를 용접대상물에 전기적으로 연결하고 용접케이블에 용접봉을 연결하여 용접대상물을 용접하게 된다. 즉, 용접대상물에 용접전류의 흐름을 형성시키기 위하여 용접전류에 비례하는 일정 용량 이상의 접지장치를 용접대상물에 부착시켜 원활한 전류흐름이 형성되도록 하는 것이다.For the above-mentioned electric welding, a welding machine is installed at a certain position, and the (-) polarity grounding cable and (+) polarity welding cable provided in the welding machine are drawn out respectively, and then the grounding device connected to the end of the grounding cable is attached to the welding object. The object to be welded is then electrically connected to the welding cable and the welding rod is connected to the welding cable. That is, in order to form a flow of welding current in the object to be welded, a grounding device of a certain capacity or more proportional to the welding current is attached to the object to be welded to form a smooth current flow.

이때, 접지장치를 용접대상물에 안정적으로 결합시키기 위하여 접지장치를 집게 형상으로 형성하는 것이 일반적이나, 용접대상물이 직경이 큰 원통 형상이거나 곡면 형상인 경우에는 집게가 안정적으로 고정되지 않고 이로 인해 접촉 불량이 발생하여 정상적인 용접이 이루어지지 않거나 용접봉이 용접대상물에 접촉되는 순간 접지부에서 아크가 발생하여 용접대상물이 손상되는 문제점이 있다.At this time, it is common to form the grounding device in the shape of a tongs in order to stably couple the grounding device to the welding object. There is a problem in that normal welding is not performed due to this occurrence, or an arc is generated in the ground portion at the moment when the welding rod comes into contact with the object to be welded, thereby damaging the object to be welded.

이에 따라, 도 8에 도시된 바와 같이, 접지케이블이 연결되는 접지부(110)와, 하단부가 곡면 형상의 용접대상물에 접촉되며 중량체로 구성되어 접지부(110)를 지지하는 클램프(120)를 포함하는 접지장치가 개발되기도 하였으나, 이 경우에는 접지부(110)에 과도한 힘이 작용할 경우에 지렛대 작용에 의해 클램프(120)가 용접대상물로부터 떨어지게 되는 문제점이 발생하고 있다.Accordingly, as shown in FIG. 8 , the grounding part 110 to which the grounding cable is connected, and the clamp 120 having the lower end in contact with the curved welding object and configured as a weight to support the grounding part 110 . Although a grounding device including a grounding device has been developed, in this case, when an excessive force is applied to the grounding unit 110, a problem occurs in that the clamp 120 is separated from the welding object by the lever action.
