본 고안은 연속 소둔작업에서 냉연강판의 절단된 부위를 접합하는 작업시 용융접합을 하지 않고서도 펀칭리벳팅형으로 접합을 할 수 있는 비용융식 접합장치에 관한 것이다.The present invention relates to a non-fusion welding apparatus capable of joining in a punching riveting type without performing a fusion bonding during the operation of joining the cut portions of the cold rolled steel sheet in the continuous annealing operation.
종래의 냉연강판 용융접합은 철판의 선,후단부를 겹친 상태에서 냉연판의 두께에 따라 접(sopt)용접기와 전기방전(Arc)용접기로 행해져 왔는데, 그 예시도면 제 1 도 (a) 및 (b)에 도시되어 있다. 그 구조 및 사용방법은 이미 널리 공지되어 있으므로 여기에서는 생략한다.Conventional cold-rolled steel sheets have been welded and welded with arc welding according to the thickness of the cold-rolled sheet in the state where the wires and the rear ends of the steel sheets are overlapped. Exemplary drawings FIG. 1 (a) and (b) ) Is shown. Its structure and method of use are already well known and are therefore omitted here.
이와 같은 종래의 점용접 및 전기방전용접기를 사용한 용접은 작업 중간과정에서 발생되는 판(板)의 파단과 정비작업중 필요시 절단된 강판의 접합수단으로 이용되어 왔다.Conventional spot welding and welding using an electric discharge welding machine have been used as a joining means of the steel sheet cut when necessary during the breaking and maintenance work of the plate generated during the operation.
상기 종래의 용접기중 점용접기의 접합방법은 냉연판의 두께가 0.4㎜이하 강판에 제한적으로 사용할 수 밖에 없고, 고전류에 의한 용접기의 헤드(head) 및 끝단부(tail)부위가 구리합금의 재질로 용융마모가 심하고 산화변색을 유발하므로 냉연판의 접합에서는 접합부가 취약하게 되고, 연속 소둔로에서 재파단(다시 파열단락)의 원인이 된다. 또한 작업공정상의 번잡성과 1회 용접시키기 위해서는 점용접을 100번 이상 실시해야 하므로 작업시간이 오래 걸리는 등의 문제점이 있었다.In the conventional welding machine, the welding method of the spot welder is limited to the cold rolled sheet having a thickness of 0.4 mm or less, and the head and the tail of the welder by high current are made of copper alloy. As the melt wear is severe and oxidative discoloration, the joint is weak in the cold-rolled joint, causing re-break in the continuous annealing furnace (again rupture short). In addition, there is a problem in that the work time takes a long time because the spot welding has to be performed more than 100 times in order to have a complicated work process and one time welding.
또 아아크 용접기의 접합방법은 냉연판 두께가 0.5㎜이상의 일반냉연강판의 접합에 사용되나, 고전류에 의한 용접봉(Φ3㎜)으로 용융접합을 하기 때문에 두께가 0.5~1.2㎜ 사이의 냉연판은 용접시 스파크에 이한 구멍과 불꽃 비산등으로 작업중 롤(Roll) 오염 및 움푹 들어간 부분(dent)발생의 요인이 되고 취급상에도 위험한 문제가 있었다.In addition, the arc welding machine is used for joining cold-rolled steel sheets with a thickness of 0.5 mm or more. However, cold-rolled plates with a thickness of 0.5 to 1.2 mm are welded because they are fused by welding rods (Φ3 mm). Holes and sparks scattered on the sparks caused roll contamination and dents during operation and were dangerous in handling.
본 고안은 상기 문제점을 해결하기 위해 고안된 것으로, 본 고안에 의한 비용융식 냉연판 접합기는 4각 오목형 상부몸체(1)와, 4각 블록형 하부몸체(2)의 일단을 리벗팅등으로 접합하되, 상기 하부몸체(2)의 선단부의 중앙부위에 연결수단에 의해 조립된 4각 뿔형 툴(5)을 장착하며, 상부몸체(1) 및 하부몸체(2)를 소정의 각도로 경사진 지지댜(stay) (3)로 지지하여서 되는 것을 특징으로 한다.The present invention is designed to solve the above problems, the non-melting cold-rolled sheet jointer according to the present invention joining one end of the four-corner concave upper body (1) and the four-block block lower body (2) by pivoting, etc. However, a four-cornered tool 5 assembled by a connecting means is mounted on the central portion of the distal end of the lower body 2, and the upper body 1 and the lower body 2 are inclined at a predetermined angle. It is characterized by being supported by a stay (3).
이하 첨부한 도면을 참조하여 일실시예를 상세히 설명한다.Hereinafter, an embodiment will be described in detail with reference to the accompanying drawings.
제 2 도는 본 발명의 비용융 접합기 구성상세도이다.2 is a detailed configuration of the non-fusion splicer of the present invention.
동도면에서 상부몸체(1)의 형태는 4각 오목형이고, 그 재료는 일반 공구강이다. 하부몸체(2)의 형태는 4각 볼록형이고, 그 재료는 역시 일반공구강이다. 상기 하부몸체의 중앙부위에는 판을 관통하는 4각 뿔형 툴(5)이 형성되어 있다. 또한 상기 상부몸체(1) 및 하부몸체(2)를 지지하는 지지대(3)는 그 경사가 대략 50R 정도이고 리벳트를 이용하여 조립한다.The upper body (1) in the figure is a four-sided concave The material is general tool steel. The shape of the lower body (2) is a four-sided convex type The material is also ordinary oral. At the center of the lower body is formed a quadrangular horn tool 5 penetrating the plate. In addition, the support (3) for supporting the upper body 1 and the lower body (2) is inclined about 50R and assembled using rivets.
상,하부의 각 몸체는 담금질처리를 하여 경화시킨 일반공구강이며 지지대는 스프링강이다. 또한, 상부 몸체는 사각오목형인데 그 특징은 윗부분이 아래부분보다 넓게 하여 강판펀칭(punching)시에 접혀지는 부분이 넓게 퍼질 수 있도록 하여 밀착이 용이하도록 되어 있다.Each upper and lower body is a general tool steel hardened by quenching treatment, and the support is spring steel. In addition, the upper body is a rectangular concave type, its feature is that the upper portion is wider than the lower portion so that the folded portion at the time of steel sheet punching (punching) can be spread widely to facilitate close contact.
다음에는 본 안의 비용융 접합기를 이용한 접합방법을 설명한다.Next, the joining method using the non-fusion joint in the present invention will be described.
먼저, 냉연판의 파단등으로 절단된 선,후행 부위를 상하로 겹친 다음 접합기의 몸체부위를 판의 폭 방향으로 넣어 상부몸체(1)에 힘을 가하면 하부몸체(2)에 조립형성된 사각뿔형 툴(Tool) (5)에 의해 겹친 판이 4각형의 구멍과 함께 끝부위가 4개소자의 삼각 다이아몬드형으로 돌출 성형된다.First, overlap the line and the trailing part cut by breaking of cold rolled plate up and down, then put the body part of the joint in the width direction of the plate and apply the force to the upper body 1, the square pyramid-shaped tool assembled to the lower body 2 The plate overlapped by (Tool) (5) is a triangular diamond of four elements with a four-hole hole It is molded to protrude.
이 과정후 끝부위를 외부로 확개시키면서 접어 밀착시키면 제 2 도에 도시된 접합된 상태부(4)와 같이 접합이 간단히 완성된다.After this process, when the end portion is folded and brought into close contact with the outside, the bonding is simply completed as shown in the bonded state portion 4 shown in FIG.
이상 일실시예에서 설명한 바와 같이 본 고안의 접합기는 취급이 간편하고 공정이 단순하여 작업시간의 단축(종래 : 40분, 본 고안 : 10분)으로 인한 생산성향상에 크게 기여할 뿐 아니라, 용융접합에 비해 접합성이 견고하고, 연속소둔과 같은 높은 온도에서도 안정성이 보장되므로 냉연강판의 접합에 다양하게 이용할 수 있다.As described in the above embodiment, the splicer of the present invention is easy to handle and the process is simple, which greatly contributes to productivity improvement due to the shortening of the working time (formerly: 40 minutes, the present design: 10 minutes), Compared to the solidity and stable at high temperatures, such as continuous annealing can be used in a variety of cold-rolled steel sheets.
