Abstract
Description
본 발명은 탄산가스(CO₂)용접기의 토치헤드 동선용접방법에 관한 것으로서The present invention relates to a torch head copper welding method of a carbon dioxide (CO₂) welding machine.
더욱 상세하게는 토치헤드에 전류를 전달하는 동선(銅線)을 고무제의 가스공급용의 고무호스가 높은 용접열에 의하여 손상되지않도록하여 납으로 용접할 수 있도록한 것이다.More specifically, the copper wire that transmits electric current to the torch head is welded with lead so that the rubber hose for rubber gas supply is not damaged by high welding heat.
종래에도 도3에 도시한 바와같이Conventionally, as shown in FIG.
전면에 팁을 고정하게된 토치헤드(1)에는 호스연결관(3)을 고정하여 가스를 공급하기위한 고무호스(4)를 연결하고 황동제로된 토치헤드(1)의 외면에는 동(구리)제의 밴드(6)로 동선(5)을 압착고정하여 전류를 황동제의 토치헤드로 전달시킬 수 있도록하고 동선의 외부에는 고무피복관(7)으로 피복하여 토치헤드부를 한쌍의 내열합성수지제의 분할손잡이(8)(8')의 내부에 설치하게된 여러종류의 탄산가스용접기가 공지되어 있으나 이는 토치헤드(1)에다 가느다란 동선(5)을 동제의 밴드(6)만으로 압착하여 고정하여서된 것이므로 동선을 통하여 전류가 토치헤드로 전달될때 각동선과 동선사이의 공간부(가)와 열에 의하여 팽창되는 밴드에의하여 토치헤드와 밴드사이의 공간이 넓어져 토치헤드에 동선의 밀착력이 느슨하게되어 전류의 전달이 매우 불량하게 이루어지게 됨과 아울러 전류의 이동저항에 의하여 밴드부위에 고열이 발생하게 되어 탄산가스용접기의 수명을 단축시키게 되었다.Torch head (1) fixed to the tip on the front is connected to the rubber hose (4) for supplying gas by fixing the hose connecting pipe (3), copper (copper) on the outer surface of the torch head (1) made of brass The copper wire 5 is crimped and fixed with a band 6 so that current can be transferred to the torch head made of brass. The outside of the copper wire is covered with a rubber coated pipe 7 to divide the torch head portion into a pair of heat-resistant resins. Various types of carbon dioxide welders installed inside the handles (8) and (8 ') are known, but they are formed by pressing and fixing a thin copper wire (5) to the torch head (1) only with a copper band (6). Therefore, when the current is transmitted to the torch head through the copper wire, the space between the copper wire and the copper wire and the band expanded by heat expands the space between the torch head and the band and loosens the adhesion of the copper wire to the torch head. Delivery is very poor As soon be well lure it becomes a high temperature occurs in the band part by movement resistance of the current was thereby shortening the life of the carbon dioxide gas welding machine.
이에따라 최근에는 열팽창계수가 낮은 황동제로된 토치헤드(1)와 열팽창계수가 높고 황동보다 연성인 동(구리)으로된 밴드(6)사이의 동선(銅線)을 납용접으로 고정하여 열에 의하여 밴드가 팽창시에도 동선의 전류를 토치헤드에 양호하게 전달시킬 수 있도록하기 위하여 황동제의 토치헤드(1)와 동제의 밴드(6)사이의 동선(5)을 납(12)으로 용접하기 위한 다양한 방법이 시도되고 있으나 동선을 납으로 용접할때 발생되는 500℃∼900℃의 높은 토치램프의 용접열에 의하여 호스연결관(3)에 고정한 120℃의 온도에서 변화되는 고무호스(4)가 손상케되기 때문에 아직까지 동선을 납용접한 제품은 생산되지 못하고 있는 실정에 놓여있다.In recent years, a copper wire is used to fix a copper wire between a torch head (1) made of brass having a low coefficient of thermal expansion and a band (6) made of copper (copper) having a higher coefficient of thermal expansion and softer than brass. For welding the copper wire 5 between the brass torch head 1 and the copper band 6 with lead 12 so that the current of the copper wire can be well transmitted to the torch head even during expansion. Although the method has been tried, the rubber hose 4 which is changed at a temperature of 120 ° C. fixed to the hose connecting pipe 3 by the welding heat of a high torch lamp of 500 ° C. to 900 ° C. generated when welding copper wire with lead is damaged. As a result, products that have been soldered with copper wire have not been produced yet.

전면에 팁(2)을 고정하게된 토치헤드(1)에는 호스연결관(3)을 고정하여 가스를 공급하기 위한 고무호스(4)를 고정하고 황동제의 토치헤드(1)의 외면에는 동선(5)을 통하여 전류를 토치헤드(1)로 전달시킬 수 있도록하고 동선(6)의 외부에는 고무피복관(7)으로 피복하여서 된것에 있어서 토치헤드(1)의 외면에 동선(6)을 압착 고정한 밴드(5)를 물탱크(9)의 상부에 설치한 홀더(10)에 삽입안치하여 호스연결관(3)에 고정한 고무호스(4)는 물탱크(9)의 냉각수(11)에 잠기게하고 밴드(6)와 납(12)을 토치램프(13)로 가열하여 밴드(6)를 팽창시킴과 동시에 녹는 납물을 토치헤드(1)와 밴드(6)사이 및 동선(5)의 공간부(5)로 스며들게하여 고무호스(4)를 손상시키지않고 납용접을 할 수 있도록한 것을 특징으로한 것이다.Fixing the hose (3) to the torch head (1) to fix the tip (2) on the front to fix the rubber hose (4) for supplying gas and copper wire on the outer surface of the torch head (1) made of brass The copper wire 6 is crimped on the outer surface of the torch head 1 in such a way that the electric current can be transmitted to the torch head 1 through 5 and the outer surface of the copper wire 6 is covered with a rubber sheath pipe 7. The rubber hose 4 fixed to the hose connecting pipe 3 by inserting and fixing the fixed band 5 into the holder 10 installed on the upper portion of the water tank 9 is immersed in the cooling water 11 of the water tank 9. Heat the band 6 and the lead 12 with the torch lamp 13 to expand the band 6 and simultaneously dissolve the molten lead between the torch head 1 and the band 6 and the space of the copper wire 5. Soaking into the part (5) is characterized in that the lead welding without damaging the rubber hose (4).
이와같은 본 발명은 물탱크(9)의 상부에 홀더(10)를 설치하여 상기의 홀더(10)에다 토치헤드(1)에 동선(5)을 압착고정한 밴드(6)를 도1과 같이 안치하고 동선(5)의 내측에 위치된 가스를 공급하는 고무호스(4)는 물탱크(9)의 냉각수에 잠기게하여 밴드(6)와 납(12)을 가열하여 녹는 납물을 토치헤드(1)와 밴드(6)및 동선의 미세공간부(가)의 사이로 스며들게하여 납용접하게 됨으로 고무호스(4)가 높은 용접온도에 의하여 손상되는 것이 방지된다. In the present invention, the holder 10 is installed on the upper portion of the water tank 9, and the band 6 in which the copper wire 5 is crimped and fixed to the torch head 1 on the holder 10 is placed as shown in FIG. And the rubber hose (4) for supplying the gas located inside the copper wire (5) is immersed in the cooling water of the water tank (9) to heat the band (6) and lead (12) to melt the lead material to the torch head (1) 2) and the band 6 and the microcavity part of the copper wire are permeated into the lead weld to prevent the rubber hose 4 from being damaged by the high welding temperature.
본 발명의 용접방법에 의하여 납용접한 제품은 전류의 발생열에 의하여 밴드(6)가 팽창될때에도 연성의 납(2)에 의하여 토치헤드(1)에는 동선(5)의 밀착력이 양호하게 유지되어 동선(5)의 전류는 토치헤드(1)에 매우 양호하게 전달된다.The product welded by the welding method of the present invention maintains good adhesion of the copper wire 5 to the torch head 1 by the flexible lead 2 even when the band 6 is expanded by the heat generated by the current.
