본 고안은 냉연스트립의 전,후단부를 용접연결하기 위한 용접장치에 관한 것으로, 보다 상세히는 냉연스트립에 접촉하여 용접작업을 이루는 용접휠의 표면으로부터 별도의 동력을 사용하지 않고서도 자동으로 불순물을 제거하고 용접휠의 표면을 균일하게 연마시킴으로서 용접불량을 최소화하도록 개선된 무동력식 용접휠 연마기에 관한 것이다.The present invention relates to a welding device for welding the front and rear ends of a cold rolled strip, and more specifically, to remove impurities from the surface of a welding wheel that makes a welding operation by contacting the cold rolled strip without using a separate power. And an improved non-powered welding wheel polishing machine for minimizing welding defects by uniformly polishing the surface of the welding wheel.

일반적으로 냉연스트립 제조공정에서는 선,후행 스트립의 단부를 서로 용접으로 연결시키는 용접기가 사용되고 있다. 이러한 용접기(100)는 제1도에 도시된 바와 같이, 전기적 전도성이 우수한 동(copper)재료로 이루어진 하부전극(112)을 갖추고, 상기 하부전극(112)의 상부로 진행하는 냉연스트립(S)을 하부전극(112)측으로 밀착시키는 한쌍의 클램프부재(114)를 갖추며, 상기 클램프부재(114)의 상부에는 상기 클램프부재(114)를 따라서 이동가능한 용접휠(11)과 상기 용접휠(116)의 측방에 위치된 전극휠(118)이 갖춰진다.In general, in the cold rolled strip manufacturing process, welders are used to connect the ends of the leading and trailing strips by welding. As shown in FIG. 1, the welder 100 includes a lower electrode 112 made of a copper material having excellent electrical conductivity, and proceeds to the upper portion of the lower electrode 112. A pair of clamp members 114 to closely contact the lower electrodes 112, and a welding wheel 11 and a welding wheel 116 movable along the clamp member 114 at an upper portion of the clamp member 114. There is an electrode wheel 118 located on the side of the.

상기 각각의 용접휠(116)과 전극휠(118)은 클램프부재(114)의 상부에서 클램프부재(114)를 따라서 연장된 가이드부재(120)에 끼워지는 대차(122)의 하부에 장착되고, 상기 전극휠(118)로는 하부전극(112)과는 반대극성의 전류가 인가되어 상기 클램프부재(114)와 하부전극(112)사이에 위치된 냉연스트립(S)에 용접전류를 가하게 되는 것이다.Each of the welding wheel 116 and the electrode wheel 118 is mounted to the lower portion of the cart 122 that is fitted to the guide member 120 extending along the clamp member 114 at the top of the clamp member 114, A current of opposite polarity to that of the lower electrode 112 is applied to the electrode wheel 118 to apply a welding current to the cold rolled strip S positioned between the clamp member 114 and the lower electrode 112.

상기와 같이 구성된 용접기(100)는 하부전극(112)의 상부측에 선,후행의 냉연스트립(S)단부가 인접하여 배치되고, 이러한 상태에서 상기 냉연스트립(S)위로 클램프부재(114)가 압착되어 하부전극(112)과의 사이에 냉연스트립(S)을 고정시키며, 상기 전극휠(118)과 하부전극(112)으로 용접전류가 인가된다. 그리고, 상기 전극휠(118)로 인가된 용접전류는 전도체로 이루어진 일측 클램프부재(114)를 통하여 냉연스트립(S)으로 공급되며, 상기 클램프부재(114)사이의 간격으로 용접휠(116)이 한쪽끝에서 다른 한쪽까지 진행하면서 선,후행 냉연스트립(S)의 단부를 압착시킴으로서 용접전류에 의해서 용융된 상태로 유지되는 선,후행 냉연스트립(S)의 단부를 서로 접합시키게 되는 것이다.The welder 100 configured as described above is disposed at the upper side of the lower electrode 112 at the end of the cold roll strip S adjacent thereto, and in this state, the clamp member 114 is positioned on the cold roll strip S. It is compressed to fix the cold rolled strip S between the lower electrode 112 and a welding current is applied to the electrode wheel 118 and the lower electrode 112. In addition, the welding current applied to the electrode wheel 118 is supplied to the cold rolled strip S through one clamp member 114 made of a conductor, and the welding wheel 116 is spaced at intervals between the clamp members 114. By adhering the ends of the line and the trailing cold rolled strips S from one end to the other, the ends of the line and the trailing cold rolled strips S maintained in a molten state by the welding current are joined together.

그러나, 상기와 같은 용접기(100)에서 장시간동안 용접작업을 수행하게되면, 용접휠(116)의 불규칙한 국부적인 마모와 동시에 용접휠(116)의 표면에 불순물이 부착되어 냉연스트립(S)의 단부를 정확하게 압착시키지 못하는 문제점이 발생한다. 이러한 경우, 선,후행 냉연스트립(S)의 단부는 서로 완벽하게 연결되지 못함으로서 이후의 통판과정에서 판파단등의 큰 설비사고를 초래하는 문제점을 갖는 것이다. 이러한 문제점을 해소하기 위해서는 정기적으로 용접휠(116)을 연마시켜야 하며, 종래의 연마방식으로는 별도의 동력을 이용한 번거로운 것이었다.However, when the welding operation for a long time in the welding machine 100 as described above, at the same time as the irregular local wear of the welding wheel 116, impurities are attached to the surface of the welding wheel 116, the end of the cold roll strip (S) There is a problem that does not exactly press. In this case, the ends of the leading and trailing cold-rolled strips (S) are not connected to each other perfectly, resulting in a large equipment accident, such as breakage in the subsequent mailing process. In order to solve this problem, the welding wheel 116 should be regularly polished, and the conventional polishing method was cumbersome using a separate power.
