탄산가스용접기의 토치헤드 동선용접방법 및 그 연결구조{Torch head copper wire welding method of carbonic acid gas welding machine and the connection structure}Torch head copper wire welding method of carbonic acid gas welding machine and the connection structure}

본 발명은 탄산가스용접기의 토치헤드 동선용접방법 및 그 연결구조에 관한 것으로, 더욱 상세하게는 황동제의 토치헤드와 동관을 먼저 1차 은납용접을 하고, 그 후 동관으로 동선을 삽입하여 압착하여서 동관과 동선을 2차 은납용접 후, 동관 내부에 삽설된 호스 연결관으로 고무호스가 삽입된 가스니플을 삽입함으로써 용접으로 인한 고무호스의 손상이 없으며, 동선과 동관을 통해 토치헤드로 전류가 전달되므로 전기 전도도가 뛰어나며, 용접방법 및 연결구조가 간단하여 작업생산이 효율적인 탄산가스용접기의 토치헤드 동선용접방법 및 그 연결구조에 관한 것이다.The present invention relates to a torch head copper wire welding method and a connection structure of a carbon dioxide gas welder, and more specifically, torch heads and copper tubes made of brass are firstly welded with silver, and then copper wires are inserted into the copper pipes to be crimped. After the second silver welding of copper pipe and copper wire, the gas hose inserted with rubber hose is inserted into the hose connector inserted inside the copper pipe so that the rubber hose is not damaged by welding and current is transmitted to the torch head through the copper wire and copper pipe. Therefore, the present invention relates to a torch head copper wire welding method and a connection structure of a carbon dioxide gas welding machine having excellent electrical conductivity, and a simple welding method and a connection structure, which are efficient in production.

일반적으로 탄산가스용접기는 토치헤드에 가느다란 동선을 동(구리)제의 동링로 압착하여 고정하여서 된 것이므로 동선을 통하여 전류가 토치헤드로 전달될 때 각 동선과 동선 사이의 공간부 및 열에 의하여 팽창되는 동제의 동링에 의하여 황동제의 토치헤드와 동선의 밀착력이 느슨하게 되어 전류의 전달이 매우 불량하게 이루어지게 됨과 아울러 전류의 이동저항에 의하여 동링부위에 고열이 발생하게 되 어 탄산가스용접기의 수명을 단축시키게 되었다.In general, carbon dioxide welders are made by pressing and fixing a thin copper wire to a torch head by copper (copper) copper rings, and when the current is transferred to the torch head through the copper wire, it expands by the space and heat between each copper wire and the copper wire. The copper copper ring made of copper makes the adhesion between the brass torch head and the copper wire loose, resulting in very poor current transfer, and high heat is generated in the copper ring area due to the resistance of the current. Was shortened.

이에 따라 최근에는 열에 의하여 동링가 팽창시에도 동선의 전류를 토치헤드로 양호하게 전달시킬 수 있도록 하기 위하여 토치헤드와 동링사이의 동선을 납으로 용접하기 위한 다양한 방법이 시도되고 있으나 동선을 납으로 용접할 때의 500℃ ~ 900℃의 높은 토치램프의 용접 열에 의하여 호스연결관에 고정한 120℃의 온도에서 변화되는 고무호스가 손상되기 때문에 아직까지 동선을 납 용접한 제품은 생산되지 못하고 있는 실정에 놓여있다.Accordingly, in recent years, various methods have been attempted to weld copper wires between the torch head and the copper rings with lead so that the current of the copper wire can be well transmitted to the torch head even when the copper ring is expanded by heat. When the rubber hose that is changed at the temperature of 120 ℃ fixed to the hose connector is damaged by the welding heat of the high torch lamp of 500 ℃ ~ 900 ℃, the lead-welded product has not been produced yet. have.

상기의 문제점을 해결하기 위하여, 도 1에 도시된 바와 같이, 물탱크(6)의 상부에 설치한 홀더(8)에다 토치헤드(1)의 외면에 동선(2)을 압착 고정한 동링(3)를 안치하여 호스연결관에 고정한 고무호스는 물탱크(6)내의 냉각수(7)에 잠기게 하고 동링(6)와 납(5)을 토치램프(9)로 가열하여 납물을 각 동선(2)과 동선(2) 사이의 공간부로 흘러들어가게 하여 고무호스를 높은 용접 열에 의하여 손상시키지 않고 용접할 수 있는 탄산가스용접기의 토치헤드 동선용접방법이 제공되었다.In order to solve the above problems, as shown in Fig. 1, the copper ring (3) by crimping and fixing the copper wire (2) on the outer surface of the torch head (1) to the holder (8) installed on the upper portion of the water tank (6) The rubber hose fixed to the hose connection pipe is immersed in the coolant (7) in the water tank (6), and the copper ring (6) and lead (5) are heated by the torch lamp (9) to lead the lead wire to each copper wire (2). A torch head copper welding method of a carbon dioxide gas welding machine capable of flowing into the space between the copper wire and the copper wire 2 so that the rubber hose can be welded without damage by high welding heat is provided.

그러나, 상기의 탄산가스용접기의 토치헤드 동선용접방법은 열팽창계수가 낮은 황동제로된 토치헤드(1)와 열팽창계수가 높은 동관은 온도차가 심하여 납이 잘 융합되지 못하여 용접이 불완전하며, 상기 황동제 토치헤드(1)의 온도에 맞추어 용접을 하면 내부의 고무호스가 변형이 일어나거나 손상되는 문제점이 있었다.However, in the torch head copper wire welding method of the carbon dioxide gas welder, the torch head 1 made of brass having a low coefficient of thermal expansion and the copper tube having a high coefficient of thermal expansion have a severe temperature difference, so that the lead is not fused and the welding is incomplete. When welding to the temperature of the torch head (1) there was a problem that the internal rubber hose is deformed or damaged.

또한, 상기 고무호스의 손상을 막기 위해 상기 물탱크(6)에 상기 고무호스를 잠기게 하여 용접을 하지만 이로 인하여 동선(2)이 부식되는 문제점이 있었다.In addition, in order to prevent the rubber hose from being damaged, the rubber hose is immersed in the water tank 6 to be welded, but this causes the copper wire 2 to be corroded.
