본 고안은 2매의 금속판을 겹쳐서 고정전극봉(21)과 가동전극봉(22) 사이에 끼우고 대전류를 통하게 하여 용접부를 점상으로 용접하는 스폿용접기에 관한 것으 로서,The present invention relates to a spot welder, which overlaps two metal plates, sandwiches between a fixed electrode rod 21 and a movable electrode rod 22, and welds a welded portion through a large current.

종래의 기술은 용접점에 따라 그때 마다 모재를 이동시켜 별도의 개별작업으로 2개의 전극봉 사이에 일일이 모재를 끼워 물려서 용접하여야 하는 불편한 단점이 있었다.The prior art has the disadvantage of having to move the base material at each time according to the welding point to weld by sandwiching the base material between the two electrodes in a separate individual operation.

종래의 이러한 불편한 단점을 개선하기 위하여 본 고안에서는 도어프레임과 같은 단면이 "ㄷ"자 형태의 용접대상물의 경우에 "ㄷ"자 형태의 용접대상물의 상, 하측에 용접할 모재를 겹쳐놓고 상측의 고정전극봉(21)과 하측의 고정전극봉(21)을 각각의 가압실린더(10)로서 가압하여 고정시킨 다음에 상, 하측의 용접점 사이의 공간에 삽입된 1개의 가동전극봉(22)만을 상, 하로 가동하게 하여 상, 하측 2개소의 용접점을 접촉, 가열하므로서 모재의 변경, 고정 작업없이 한번에 상, 하측 2개소의 연속용접이 가능하도록 창안한 도어프레임용 스폿용접기에 대한 것이다. In order to improve such a disadvantage in the prior art in the present invention, in the case of the welding object of the "c" shaped cross section, such as the door frame, the base material to be welded on the upper and lower sides of the "c" shaped welding object is overlapped. The fixed electrode 21 and the lower fixed electrode 21 are pressurized and fixed as the respective pressure cylinders 10, and then only one movable electrode 22 inserted into the space between the upper and lower welding points is provided. The present invention relates to a spot welder for door frames designed to allow continuous welding of two upper and lower portions at once without changing the base material and fixing work by contacting and heating two upper and lower welding points.

스폿용접(spot-welding)은 용접될 두 개 또는 그 이상의 용접물(금속판)인 모재을 겹쳐 전극봉 사이에 끼워 접점 시키고, 접점부위에 대전류를 통하게 하여 전극봉과 용접물과의 접점부위를 대전류로 가열하여 용접물이 용접온도에 달하도록 하여 점상으로 용접하는 것을 스폿용접이라 하며 이 스폿용접은 스폿용접기로 용접을 할 수 있다. Spot welding is made by placing two or more welding materials (metal plates) to be welded together and sandwiching the base material between electrodes to make contact, and passing the large current through the contact area to heat the contact area between the electrode and the welding material with high current. Spot welding is achieved by reaching the welding temperature. Spot welding can be performed by spot welding.

This spot welder is suitable for the plate-shaped weldment, but the welder such as the door frame, which requires the welding of the upper and lower portions such as the "c" type or the "h" type, first welds the upper and lower portions, and then There was a problem that the work efficiency is lowered because it has to turn over and weld the other side again.
