Description
본 고안은 이산화탄소가스용접기의 용접기본체와 와이어송급장치 사이에 설치되는 싱글케이블에 관한 것으로, 더 자세하게는 이산화탄소가스공급관과 외부관 사이에 설치되는 메인 전원선 및 피복 전선을 효율적으로 배열한 것에 관한 것이다.The present invention relates to a single cable installed between the welding main body of the carbon dioxide gas welder and the wire feeding device, and more particularly, to the efficient arrangement of the main power line and the sheathed wire installed between the carbon dioxide gas supply pipe and the outer pipe. .
일반적으로 이산화탄소가스용접기는 연속적으로 공급되는 소모식 용접봉과 용접하고자 하는 모재 사이에 전기적 아크를 발생시키는 동시에 용융지 보호를 위하여 토오치 선단에 형성된 가스노즐을 통해 순수한 이산화탄소가스를 분출시켜 용접부 주위의 공기를 밀어내어 차단함으로써 용접금속의 산화 및 질화를 방지하여 양호한 용접부을 형성시키는 것으로, 조선이나 그 밖의 각종 산업현장에서 널리 사용되고 있고 있다.In general, a carbon dioxide gas welding machine generates an electric arc between a continuously supplied consumable electrode and a base material to be welded, and simultaneously blows out pure carbon dioxide gas through a gas nozzle formed at the tip of the torch to protect the molten paper. It is widely used in shipbuilding and other various industrial sites by pushing and blocking to prevent oxidation and nitriding of the weld metal to form a good weld.
상기 이산화탄소가스용접기는 용접기본체와 와이어송급장치, 그리고 용접토오치로 이루어지는 것이 보통이며, 본 고안의 싱글케이블은 용접기본체와 와이어송급장치 사이에 설치되어 용접기본체로부터 공급되는 이산화탄소가스와 제어신호, 전원을 와이어송급장치로 전달할 수 있도록 하는 싱글케이블에 관계한다.The carbon dioxide gas welding machine is generally composed of a welding main body, a wire feeding device, and a welding torch, and the single cable of the present invention is installed between the welding main body and the wire feeding device, and the carbon dioxide gas, the control signal, and the power supply are supplied from the welding main body. It relates to a single cable that can be delivered to a wire feeder.
최근 들어 상기 싱글케이블은 도 1 및 도 2와 같이 외부관과 그 내부의 이산화탄소가스공급관의 사이에 절연피복된 신호선, 모터 전원선, 그라운드선, 솔레노이드 전원선과 절연피복되지 않은 메인 전원선이 설치된 형태의 것이 주로 사용되고 있는 실정이다.In recent years, the single cable has a form in which an insulating coated signal line, a motor power line, a ground line, a solenoid power line and an uninsulated main power line are installed between an outer tube and a carbon dioxide gas supply tube therein as shown in FIGS. 1 and 2. The situation is mainly used.
도 1에 도시한 종래의 한 싱글케이블(10; 특허 제88301호)은 외부관(11)과 그 내부의 이산화탄소가스공급관(12) 사이의 공간에 신호선, 모터 전원선, 그라운드선, 솔레노이드밸브 전원선을 포함한 절연피복 통신선(13)을 방사상으로 배열하고, 각 절연피복 통신선(13) 사이에 메인 전원선(14)을 배열 설치한 것으로, 직경이 서로 다른 절연피복 통신선(13)과 메인 전원선(14)이 균형적으로 배열되어 외부 압력이 가해지더라도 이산화탄소가스공급관(12) 및 외부관(11)이 안정적인 형태를 유지할 수 있게 되는 것이지만 다수의 메인 전원선(14)이 서로 분리되어 있기 때문에 저항값이 커지게 되고, 그에 따라 각 메인 전원선(14)의 직경을 크게 하여야 하므로 외부관(11)의 직경이 커지게 됨은 물론 메인 전원선(14)의 무게 및 외부관(11)의 무게가 무겁게 되어 제작이 번거롭게 되고, 취급, 운반 및 설치 작업성이 나쁘게 되는 문제가 있었다.A conventional single cable 10 (Patent No. 88301) shown in FIG. 1 has a signal line, a motor power line, a ground line, and a solenoid valve power supply in a space between an outer tube 11 and a carbon dioxide gas supply tube 12 therein. The insulation coating communication line 13 including the wire was arranged in a radial manner, and the main power supply line 14 was arranged between each insulation coating communication line 13, and the insulation coating communication line 13 and the main power line having different diameters were installed. Although the 14 is arranged in a balanced manner, the carbon dioxide gas supply pipe 12 and the external pipe 11 can maintain a stable shape even when an external pressure is applied, but the resistance is because a plurality of main power lines 14 are separated from each other. As the value increases, the diameter of each main power line 14 must be increased accordingly, so that the diameter of the outer tube 11 increases, as well as the weight of the main power line 14 and the weight of the outer tube 11. Heavy and cumbersome production And there has been a problem that the handling, transportation and installation workability worse.
도 2에 도시한 종래의 다른 싱글케이블(20; 실용신안등록 제140846호)은 외부관(21)과 그 내부의 이산화탄소가스공급관(22) 사이의 공간 일측과 타측에 모터 전원선을 포함한 절연피복 통신선(23)과 메인 전원선(24)을 서로 분리하여 배열 설치한 것으로, 다수의 메인 전원선(24)이 분리되지 않고 한 곳에 모여 있기 때문에 전술한 것과는 달리 전체 메인 전원선(24)의 저항값은 비교적 작게 되지만 직경이 서로 다른 메인 전원선(24)과 절연피복 통신선(23)이 이산화탄소가스공급관(22)의 좌측과 우측에 각각 배열 설치되기 때문에 균형을 이루지 못하게 되어 외부 압력이 가해지게 되면 외부관(21) 및 이산화탄소가스공급관(22)이 찌그러지게 되는 등의 변형이 발생하게 되므로 내구성이 약하게 됨은 물론 이산화탄소가스의 공급효율 및 용접효율이 저하되는 등의 문제가 있었다. Another conventional single cable 20 shown in Figure 2 (Utility Model Registration No. 140846) is an insulating coating including a motor power line on one side and the other side of the space between the outer tube 21 and the carbon dioxide gas supply pipe 22 therein. The communication line 23 and the main power line 24 are arranged separately from each other, and since the plurality of main power lines 24 are gathered in one place without being separated, the resistance of the entire main power line 24 is different from the above. The value becomes relatively small, but the main power line 24 and the insulation coating communication line 23 having different diameters are arranged on the left and right sides of the carbon dioxide gas supply pipe 22, so that they are not balanced, so that external pressure is applied. Deformation such as crushing of the outer tube 21 and the carbon dioxide gas supply pipe 22 causes the durability to be weak, as well as the supply efficiency and the welding efficiency of the carbon dioxide gas are lowered. There was.
본 고안은 상기와 같은 종래의 이산화탄소가스용접기용 싱글케이블의 제결함을 감안하여 안출한 것이며, 그 목적이 보다 안정적으로 외부 충격에 의한 변형을 억제할 수 있도록 함은 물론 경량화를 통해 제작 및 취급을 간편하게 할 수 있도록 하는 이산화탄소가스용접기용 싱글케이블을 제공하는 데에 있는 것이다.The present invention was devised in view of the deficiency of the conventional single cable for carbon dioxide gas welding machine as described above, and its purpose is to more stably suppress the deformation caused by external impact, and to manufacture and handle the product through light weight. It is to provide a single cable for the carbon dioxide gas welding machine to make it simple.
