일반적으로 냉연코일의 생산공정에서는 선행코일과 후행코일을 연결하기 위하여 자동용접기에서 선행코일의 후단과 후행코일의 선단을 용접하게 된다.In general, in the production process of cold rolled coils, in order to connect the preceding coil and the following coil, the end of the preceding coil and the tip of the trailing coil are welded by the automatic welding machine.
이때 코일의 용접부의 용접상태를 점검하기 위하여 재료실험실에 의뢰하거나현장작업자가 육안에 의한 상태점검을 하게 된다.At this time, in order to check the welding condition of the welded part of the coil, ask the material laboratory or check the condition by visual field worker.
그러나 상기와 같은 종래의 용접부 검사방법은 재료실험실 검사방법의 경우 검사시간이 많이 소요되어 현장적용이 어렵고, 육안체크방법의 경우 작업자에 따라 그 판단기준을 달리하기 때문에 정확한 용접상태를 판별하기 어렵다.However, in the conventional welding part inspection method as described above, it is difficult to apply the site due to a large amount of inspection time in the material laboratory inspection method, and the visual inspection method is difficult to determine the exact welding state because the judgment criteria are different depending on the operator.
본 고안은 냉연코일의 생산공정에서 선행코일의 후단부와 후행코일의 선단부의 연결을 위해 자동용접기에서 용접하게 되는데, 이때 용접부의 용접상태를 정확히 판별할 수 있는 스트립의 노칭(Notching) 용접부 검사장치를 제공함에 그 목적이 있다.The present invention is welded by an automatic welding machine for connecting the rear end of the preceding coil and the front end of the trailing coil in the production process of the cold rolled coil. The purpose is to provide.

상기한 목적을 달성하기 위하여 본 고안은 몸체의 상단부에 실린더에 의해 전후진 이동되도록 내장되는 밀대와; 상기 밀대의 경사면을 따라 탄성에 의한 상하이동되도록 상기 몸체에 내장되고, 하단부에 해머가 수직으로 체결되는 베이스와; 상기 몸체의 하단부에 부착되면서 상면에 상기 해머의 하단면이 안착되는 홈이 형성되는 하부받침대와; 상기 하부받침대의 상부 일측 회전 가능하도록 결합되면서 상기 해머에 의해 관통되는 홀이 형성되는 시편고정커버로 구성되는 것을 특징으로 하는 스트립의 노칭 용접부 검사장치를 제공한다.The present invention to achieve the above object is a push rod that is built to move forward and backward by the cylinder to the upper end of the body; A base which is embedded in the body so as to be moved by elasticity along an inclined surface of the push rod, and a hammer is vertically fastened to a lower end thereof; A lower supporter attached to a lower end of the body and having a groove formed therein, the lower end of the hammer being seated on an upper surface thereof; It provides a notching weld inspection device of the strip, characterized in that consisting of a specimen fixing cover is formed so that the hole penetrated by the hammer while being coupled to the upper one side of the lower support.
도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.
도1은 본 고안에 따른 스트립의 노칭 용접부 검사장치를 나타내는 일부단면도이다1 is a partial cross-sectional view showing a notching weld inspection device of the strip according to the present invention.
먼저 몸체(1)의 우측면 상단부에는 에어실린더(2)가 좌우방향으로 전후진되도록 볼트 체결되어 있고, 이 에어실린더(2)에는 양단측에 각각 전후진에어라인(16-2,16-1)이 연결되어 있으며, 이 전후진에어라인은 에어절환밸브(13)에 의해 절환된다.First, the upper end of the right side of the body 1 is bolted so that the air cylinder 2 forwards and backwards in the left and right directions, and the air cylinders 2 have forward and backward air lines 16-2 and 16-1 at both ends, respectively. This forward and backward air line is switched by the air switching valve (13).
그리고 몸체(1)의 상단부에 좌우 수평이동되도록 내장되는 밀대(4)는 우측면에 에어실린더(2)의 로드 선단이 체결되어 있고, 에어실린더(2)에 의해 좌측으로 전진되면서 좌측 하부에 형성되는 경사면(4-1)이 해머이동베이스(3)의 상면에 접촉되면서 해머이동베이스를 밑으로 밀게 된다.And the rod (4) that is built so as to move horizontally left and right on the upper end of the body (1) is the rod end of the air cylinder (2) is fastened to the right side, and is formed in the lower left while advancing to the left by the air cylinder (2) The inclined surface 4-1 is in contact with the upper surface of the hammer moving base 3 to push the hammer moving base downward.
또한 몸체(1)에 스프링(5)에 의해 상하 탄성이동하도록 내장되는 해머이동베이스(3)는 상면이 경사면(4-1)에 탄성 밀착되어 있고, 하부에 수직으로 삽입되는 해머(9)가 스토퍼판(7)와 체결볼트에 의해 고정되어 있다.In addition, the hammer movement base (3), which is embedded in the body (1) by the spring (5) to move up and down elastically, the upper surface is elastically in close contact with the inclined surface (4-1), the hammer (9) inserted vertically in the lower portion It is fixed by the stopper plate 7 and the fastening bolt.
한편 해머(9)의 하부에 위치하도록 몸체(1)에 볼트에 의해 고정되는 하부받침대(11)는 상면 중앙에 해머의 하단이 삽입될 수 있도록 해머홈(11-1)이 형성되어 있다.Meanwhile, the lower support 11 fixed to the body 1 by a bolt to be positioned below the hammer 9 is provided with a hammer groove 11-1 so that the lower end of the hammer can be inserted into the center of the upper surface.
그리고 하부받침대(11)의 상면 일측에 회전 가능하도록 핀결합되어 있는 시편고정커버(10)에는 하강되는 해머(9)가 관통하여 해머홈(11-1)에 안착될 수 있도록 해머홀(10-1)이 형성되어 있다.In addition, the specimen fixing cover 10 which is pin-coupled to one side of the upper surface of the lower support 11 to allow the hammer 9 to be penetrated and to be seated in the hammer groove 11-1 is fitted into the hammer hole 10-1. 1) is formed.
도2는 본 고안에 따른 스트립의 노칭 용접부 검사장치에 의해 검사되는 시편을 나타내는 개략도이다.Figure 2 is a schematic diagram showing a specimen to be inspected by the notching weld inspection device of the strip according to the present invention.
선행코일(14-1)과 후행코일(14-2)을 용접기에서 용접할 경우 스트립의 폭이일치하지 않아 후공정으로 이동시 노칭 용접부(13)에서 돌출되는 선행코일이 측면설비에 부딪치면서 그 충격으로 용접부가 절단되는 경우가 있다.When the leading coil 14-1 and the trailing coil 14-2 are welded in the welding machine, the width of the strip does not match, and the preceding coil protruding from the notching weld 13 when hitting the side process hits the side equipment and the impact thereof. The weld may be cut off.
따라서 이러한 문제점을 개선하는 동시에 가장 취약한 노칭 용접부(13)의 용접상태를 시험하기 위하여 시편(12)을 채취하게 된다.Therefore, to improve this problem and at the same time take the specimen 12 in order to test the weld state of the weakest notched weld (13).
이하 본 고안의 작용을 설명한다.Hereinafter will be described the operation of the present invention.
먼저 시편고정커버(10)를 오픈(Open)시킨 후, 용접부(13)가 해머홈(11-1)의 지름방향으로 위치하도록 시편(12)을 하부받침대(11)에 올려 놓은 다음, 다시 시편고정커버(10)를 크로스(Close)하여 시편을 눌러 고정시킨다.First, after opening the specimen fixing cover 10, the specimen 12 is placed on the lower support 11 so that the welded portion 13 is located in the radial direction of the hammer groove 11-1, and then the specimen again. Close the fixing cover 10 and press down to fix the specimen.
그리고 에어절환밸브(13)를 조작하여 전진에어라인(16-2)으로 에어를 공급하면 에어실린더(2)가 전진되면서 밀대(4)도 전진하게 되고, 해머이동베이스(3)는 밀대의 경사면(4-1)을 따라 하강하게 된다.Then, when the air is supplied to the advance air line 16-2 by operating the air switching valve 13, the air cylinder 2 is advanced and the pusher 4 is also advanced, and the hammer moving base 3 is the inclined surface of the pusher. Descend along (4-1).
이때 해머이동베이스(3)에 의해 수직 하강되는 해머(9)는 해머홀(10-1)을 관통하여 시편(12)의 노칭(Notching)용접부(13)를 해머홈(11-1)측으로 눌러 용접상태를 검사하게 된다.At this time, the hammer 9 which is vertically lowered by the hammer moving base 3 penetrates the hammer hole 10-1 and presses the notching weld 13 of the specimen 12 toward the hammer groove 11-1. Inspect the welding condition.
본 고안은 냉연코일의 생산공정에서 선행코일의 후단부와 후행코일의 선단부의 연결을 위해 자동용접기에서 용접하게 되는데, 이때 노칭(Notching)용접부의 용접상태를 정확히 판별할 수 있는 효과를 제공한다.The present invention is welded in the automatic welding machine for the connection of the rear end of the preceding coil and the front end of the trailing coil in the production process of the cold rolled coil, at this time provides an effect that can accurately determine the welding state of the notching weld.
