Description

박판 파이프 자동용접장치Sheet pipe automatic welding device

본 발명은 용접 장치에 관한 것으로, 특히 박판으로 제작되는 파이프의 접합부의 용접 작업을 자동화하여 박판 파이프의 품질과 강도를 향상시킬 수 있는 박판 파이프 자동용접장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding apparatus, and more particularly, to an automatic welding apparatus for a thin-pipe, which can improve the quality and strength of a thin-walled pipe by automating the welding work of a joint of a pipe manufactured from a thin-plate.

각종 대형 구조물에 사용되는 파이프는 소형의 경우 파이프 제작 공장에서 일괄 생산되지만, 일정한 규격만을 갖고 있어, 생산 현장의 다양한 요구를 수용하기 위해서는 한계가 있게 된다.Pipes used in various large structures are produced in a small scale in a pipe fabrication factory, but have a certain size, so there is a limit to accommodate various needs of the production site.

생산현장의 수요를 충족하기 위해서는 일정한 두께의 철판을 둥글게 말아 각 단부를 용접하므로서 파이프를 제작하게 된다.In order to meet the demand of the production site, a steel plate of constant thickness is rolled and welded to each end to produce a pipe.

기존의 방법은 박판의 양단부를 작업자가 수동용접하는 방법을 사용하고 있으나, 박판을 둥굴게 말아 일정한 힘을 주어 고정시키는 경우 박판이 둥글게 말려있기 때문에 박판에서 발생하는 탄력에 의해 위치를 잡기 힘들며 박판의 양단부를 용접할 때 전체 용접선이 균일하게 용접되지 않으면 사용할 때 용접강도가 약한 곳에 균열이 생기게 되지만, 용접선 선체를 균일하게 용접하기 위해서는 작업자의 숙련을 필요로 하는 문제점이 있게된다.The conventional method uses manual welding of both ends of the sheet, but when the sheet is rolled up and fixed by applying a constant force, the sheet is rolled up so that it is difficult to position due to the elasticity generated from the sheet. When welding both ends, if the entire welding line is not uniformly welded, cracks are generated at the weak weld strength when used, but there is a problem that requires the skill of an operator to uniformly weld the welding line hull.

본 발명은 위와같은 문제점을 해소하기 위해 안출된 것으로, 박판을 둥글게 말아 그 단부를 용접함에 있어, 용접을 자동화하여 박판 파이프의 품질을 향상시킬 수 있는 박판 파이프 자동용접장치를 제공하는 것을 목적으로 한다.The present invention has been made in order to solve the above problems, it is an object of the present invention to provide a thin-plate automatic welding device that can improve the quality of the thin pipe by automating welding in rolling the thin plate round the end. .

상기 목적을 달성하기 위한 본 발명 박판 파이프 자동용접장치는 사상 형태로 연동하며 박판 파이프를 일정 위치에서 고정하는 연동암, 상기 연동암이 설치되는 회전판, 구동축이 상기 회전판과 연결되어 회전판을 일정한 각속도로 회전시키는 회전모터, 용접 장치를 좌우 이동시키는 이동 장치, 서로 마주하는 면에 상기 회전판이 설치되는 지지대로 구성되는 것을 특징으로 한다.In accordance with an embodiment of the present invention, a thin-plate automatic welding device for achieving the above object is provided with an interlocking arm for interlocking and fixing the thin-walled pipe at a predetermined position. The rotating motor to rotate, the moving device for moving the welding device left and right, characterized in that it is configured as a support that is provided with the rotating plate on the surface facing each other.

제1도는 본 발명에 따른 박판 파이프 자동용접장치의 구성을 나타내는 사시도.1 is a perspective view showing the configuration of a thin plate automatic welding device according to the present invention.

이하, 본 발명을 첨부된 도면들을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 박판 파이프 자동용접장치의 구성을 나타내는 사시도로서, 용접 장치에 있어서, 방사상 형태로 연동하며 박판 파이프를 일정 위치에서 고정하는 연동암(10), 상기 연동암(10)이 설치되는 회전판(15), 구동축이 상기 회전판(15)과 연결되어 회전판(15)을 일정한 각속도로 회전시키는 회전모터(20), 용접장치(5)를 좌우 이동시키는 이동장치(25), 서로 마주하는 면에 상기 회전판(15)이 설치되는 지지대(30)로 구성되어 있음을 도시하고 있다.1 is a perspective view showing the configuration of a thin plate automatic welding device according to the present invention, in the welding device, the linkage arm 10, the linkage arm 10 for interlocking in a radial form and fixing the sheet pipe at a predetermined position is The rotating plate 15 is installed, the drive shaft is connected to the rotating plate 15, the rotating motor 20 for rotating the rotating plate 15 at a constant angular speed, the moving device 25 for moving the welding device 5 left and right, facing each other It is shown that the rotating plate 15 is composed of a support 30 is installed on the surface.

또한 상기 지지대(30)의 일측은 좌우로 이동 가능하도록 구성되어 있다.In addition, one side of the support 30 is configured to be movable left and right.

상기 도 1을 참조하여 본 발명을 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to FIG. 1 as follows.

하체(6)의 양측에는 하체(6)와 수직으로 지지대(30)가 설치되어 있고, 양측의 지지대(30)의 서로 마주보는 내측에 설치되어 있는 회전판(15)에 설치되어 있으며, 회전판(15)에는 일정한 지름으로 둥그렇게 말린 박판 파이프를 연동암(10)을 이용하여 고정한다.Supports 30 are provided on both sides of the lower body 6 perpendicularly to the lower body 6, and are provided on the rotating plate 15 provided on the inner side of the support 30 on both sides, and the rotating plate 15. ) Is fixed to the sheet pipe rolled to a certain diameter using a linkage arm (10).

회전판(15)에 설치되어 있는 연동암(10)은 하나의 연동암(10)을 회전판(15)의 중심에서 외측으로 또는 외측에서 중심측으로 움직이게 되면 다른 연동암(10)도 같은 방향으로 같은 이동량을 움직이는 것으로, 선반에서 공작물을 고정시키는 바이스와 유사한 구조로 볼 수 있다.The linkage arm 10 installed on the rotating plate 15 moves one linking arm 10 from the center of the rotating plate 15 to the outside or from the outside to the center side, so that the other linking arm 10 moves in the same direction. It can be seen as a structure similar to a vise that holds a workpiece on a lathe.

박판 파이프의 안쪽에서 연동암을 이용하여 박판 파이프를 고정한 후 4개의 연동암(10)이 내측에서 외측을 향하여 움직이며 박판 파이프를 고정하게 된다. 연동암(10)에 의해 박판 파이프를 고정하므로 다양한 지름을 갖는 박판 파이프에 대응할 수 있다.After fixing the thin pipe using the interlocking arm in the inner side of the thin pipe four interlocking arm 10 is moved from the inside toward the outside to fix the thin pipe. Since the thin pipe is fixed by the interlocking arm 10, it is possible to cope with the thin pipe having various diameters.

회전모터(20)는 양측 지지대(30)의 외측에 설치되고, 회전모터(20)의 구동축은 연동암(10)이 설치되어 있는 회전판(15)과 연결되어 있어, 박판 파이프가 고정된 후 작업자는 박판 파이프의 양단 접합부를 찾아, 용접기를 수직으로 내리면 용접기의 토치부분이 접합부에 닿을 수 있도록 회전모터(20)를 동작시킨다.The rotary motor 20 is installed on both sides of the support 30, the drive shaft of the rotary motor 20 is connected to the rotary plate 15, the linkage arm 10 is installed, the worker after the thin plate pipe is fixed Find the joints of both ends of the thin pipe, and when the welding machine is lowered vertically to operate the rotary motor 20 so that the torch portion of the welder can reach the joint.

또한, 다양한 길이를 갖는 박판 파이프에 대응하기 위하여 일측의 지지대(30)는 고정되어 있으나, 타측의 지지대(30)는 좌우로 이동가능하도록 해야 한다.In addition, the support 30 on one side is fixed to correspond to the thin-walled pipe having various lengths, the support 30 on the other side should be movable to the left and right.
