Description
본 발명은 전기용접에 사용되는 용접기에 관한 것으로서 보다 상세하게는 통합용접기의 전극변환장치가 구비된 휴대형 용접용 전원장치에 관한 것이다.The present invention relates to a welding machine used for electric welding, and more particularly, to a portable welding power supply device having an electrode conversion device of the integrated welding machine.
그리고, 본 발명은 용접장치에 관한 것으로서 보다 상세하게는 전극변환장치와 용접토치헤드 냉각 및 용접흄 처리장치를 구비한 휴대형 용접용 전원장치에 관한 것이다. In addition, the present invention relates to a welding device, and more particularly, to a portable welding power supply device having an electrode conversion device, a welding torch head cooling, and a welding fume treatment device.
용접은 상호 결합시킬 별도의 금속재료를 맞대거나 겹친 상태로 접합부위를 가열 및 용융시켜 붙이는 접합방법이다. 이는 기계나 건축 토목은 물론 전기전자 분야 등을 포함하는 산업전반에 걸쳐 광범위하게 사용되는 기술로서, 고품질, 고생산성, 안전성 등과 같은 요구를 충족시키기 위하여 계속적으로 개발되고 있다.Welding is a joining method in which separate and joined metal materials to be bonded to each other are heated and melted in a state where they are joined together or overlapped. It is a technology widely used throughout the industry including the fields of machinery and civil engineering, as well as electrical and electronic fields, and is being continuously developed to meet demands such as high quality, high productivity, and safety.
이러한 용접에는, 용접할 소재나 사용하는 전류량에 따라, CO2용접, MIG용접, MAG용접, TIG용접 등으로 구분되기도 하고, 전기를 사용하는지 가스를 사용하는지에 따라 아크용접, 가스용접으로 분류되기도 한다.Such welding may be classified into CO2 welding, MIG welding, MAG welding, TIG welding, etc., depending on the material to be welded and the amount of current used, or may be classified into arc welding or gas welding depending on whether electricity is used or gas. .
상기한 용접 중 아크용접은, 용접을 위해 아크방전을 유도하는 용접법으로서, 탄소아크용접과, 금속아크용접과, 고주파아크용접이 포함된다. 또한, 이러한 아크용접 중 CO2용접과 MIG용접은 소모성전극을 사용하는 용접법이다. The arc welding of the above welding is a welding method of inducing arc discharge for welding, and includes carbon arc welding, metal arc welding, and high frequency arc welding. In addition, the CO2 welding and the MIG welding of the arc welding is a welding method using a consumable electrode.
즉, 릴(reel)로부터 연속적으로 풀려 나오는 와이어전극의 선단부를 모재에 형성된 아크속으로 연속 공급하여 와이어전극이 열에 의해 용융되도록 함으로써, 모재에 용착된 용융부를 형성하고 상기 용융부가 응고되면서 용접이 이루어지도록 하는 것이다.That is, by continuously supplying the front end of the wire electrode continuously released from the reel into the arc formed in the base material so that the wire electrode is melted by heat, thereby forming a melted portion welded to the base material and welding while the melted part solidifies. To lose.
이에 비해, TIG용접은 비소모성 텅스텐 전극을 사용하는 용접법으로서, 전극과 모재 사이에 아크를 발생시키고 용가봉을 공급하여 용착을 이루는 용접법이다. In contrast, TIG welding is a welding method using a non-consumable tungsten electrode, which generates an arc between the electrode and the base material and supplies welding rods to achieve welding.
특히 TIG용접은 CO2용접이나 MIG용접과 달리 모재에 플러스전극을 연결하고 용접토치에 마이너스전극을 접속하고, CO2용접이나 MIG용접은 모재에 마이너스의 전극을 연결하고 용접토치에 플러스전극을 연결하여 용접을 수행한다.In particular, unlike CO2 welding or MIG welding, TIG welding connects the positive electrode to the base material and connects the negative electrode to the welding torch, and CO2 welding or MIG welding connects the negative electrode to the base material and the plus electrode to the welding torch. Do this.
이에 따라, 가령 하나의 용접기를 CO2용접과 TIG용접에 번갈아 사용해야 할 경우에는, 작업자가 번번히 용접기의 커버를 열고 내부의 볼트 등을 풀어 용접선을 수동으로 교체하여 극성을 전환하여야 하였다. 이는 매우 불편한 일이며 작업능률을 크게 떨어뜨리는 원인이 된다.Accordingly, when one welder needs to be alternately used for CO2 welding and TIG welding, the worker has to open the cover of the welding machine, loosen the bolts inside, and replace the welding wire manually to switch the polarity. This is very inconvenient and causes a great deal of loss of work efficiency.
이러한 문제를 해결하기 위하여 국내등록실용신안공보 제20-0380648호(아크겸용 티그용접기의 전극 전환장치)가 제안된 바 있다. 상기 종래의 전환장치는, 직류공급판에 접점레버를 회전가능하게 설치하고, 접점레버를 솔레노이드밸브와 기체에 의해 작동되는 실린더 및 콘트롤스위치를 통해 원격 조작으로 회전시켜 아크용접 또는 티그용접을 선택적으로 행할 수 있도록 구성되어 있다. In order to solve such a problem, Korean Registered Utility Model Publication No. 20-0380648 (electrode switching device of an arc combined TIG welding machine) has been proposed. In the conventional switching device, the contact lever is rotatably installed on the DC supply plate, and the contact lever is rotated by a remote operation through a cylinder and control switch operated by a solenoid valve and a gas to selectively perform arc welding or TIG welding. It is comprised so that it can be performed.
그런데 상기한 종래의 전극 전환장치는, 솔레노이드밸브와 콘트롤스위치는 물론 실린더와 각종 링크기구 등를 포함하므로 그 구성이 매우 복잡하고 부피가 크며 무겁다는 단점이 있었다. However, the conventional electrode switching device has a disadvantage that the configuration is very complicated, bulky and heavy because it includes a solenoid valve and a control switch as well as a cylinder and various link mechanisms.
한편, 상기한 와이어 피딩 방식의 용접은, 용접작업을 연속적으로 진행하므로 능률적이기는 하지만 와이어전극의 송급속도에 따라 용접전류가 증가하게 된다. 그런데, 증가된 대전류로 장시간 용접할 경우 용접토치의 파워케이블이 과열되어 손상되거나 심할 경우 화재발생의 위험이 있다. 게다가 토치의 노즐, 인슈레다 등이 쉽게 마모되어 토치의 수명이 단축되는 등 작업능률이 저하를 초래할 수 도 있다.On the other hand, the welding of the wire feeding method is efficient because the welding operation proceeds continuously, but the welding current increases according to the feeding speed of the wire electrode. However, when welding for a long time with increased large current, the power cable of the welding torch is overheated and damaged or there is a danger of fire. In addition, torch nozzles, insureds, etc. can easily wear out, resulting in a reduction in work efficiency, such as shortening the life of the torch.
이에 따라, 파워케이블의 단면적을 크게 제작한다거나 수냉장치를 적용하여 토치전단부로 냉각수를 순환시키는 등의 시도가 있었다. 그러나 파워케이블의 단면적을 크게 하는 것은 비용의 상승을 유발하고, 토치의 무게를 증가시켜 작업능률을 저하시킨다는 단점이 있고, 수냉장치의 적용의 경우 누수로 인한 용접결함의 위험이 있다.Accordingly, there have been attempts to make the cross-sectional area of the power cable large or to apply the water cooling device to circulate the coolant through the torch front end. However, increasing the cross-sectional area of the power cable causes an increase in cost, increases the weight of the torch and lowers work efficiency, and in the case of the application of a water cooling device, there is a risk of welding defect due to leakage.
이러한 이유로 냉각용 에어를 이용하여 토치를 냉각하는 방식도 제안된 바 있다. 가령, 국내등록특허 제10-0680240호에는 파워케이블과 토치의 외주면에 냉각용 에어를 접촉시켜 냉각을 수행함과 아울러 토치바디에는 공급된 에어를 토치의 후방으로 유도하는 에어유도관 등을 적용한 기술이 소개되어 있다.For this reason, a method of cooling the torch using cooling air has also been proposed. For example, Korean Patent No. 10-0680240 discloses a technology in which cooling air is contacted to the outer circumferential surface of a power cable and a torch to perform cooling, and an air induction pipe for inducing the supplied air to the rear of the torch is applied. It is introduced.
그런데 상기한 선행문헌에 개시되어 있는 용접토치는, 외부로부터 에어를 공급받아 냉각을 도모하는 것이기는 하지만, 냉각용 에어를 필터링 한 후 공급하는 것이 아니기 때문에, 오염 물질이 에어와 함께 에어통로로 유입될 수 도 있다는 단점을 갖는다. 먼지나 미세한 모래 등이 에어통로로 유입되면 유로가 점차 막히게 되고 애초 예상한 냉각효과를 얻을 수 없게 된다.By the way, the welding torch disclosed in the above-mentioned prior document is intended to cool by receiving air from the outside, but is not supplied after filtering the cooling air, so that contaminants enter the air passage together with the air. It has the disadvantage that it can be. If dust or fine sand enters the air passage, the passage will be gradually blocked and the expected cooling effect will not be achieved.

상기 전극변환장치(15)는 도 2 내지 도 4에 나타내 보인 구조를 가지는 것으로서, 필요에 맞추어 출력전극을 전환하는 기능을 한다. 이를테면 접지포트(17)로 마이너스전극, 토치접속포트(19)로 플러스전극을 내보내던가, 반대로 접지포트(17)에 플러스전극, 토치접속포트(19)에 마이너스전극을 출력하는 것이다.The electrode converter 15 has a structure shown in Figs. 2 to 4, and functions to switch output electrodes as necessary. For example, the negative electrode may be sent to the ground port 17 and the positive electrode to the torch connection port 19, or the positive electrode may be output to the ground port 17 and the negative electrode to the torch connection port 19.
상기 전극변환장치(15)를 구성하는 커버플레이트(15b)와 레버(15a)는 케이싱(13)의 외부로 노출되어 작업에 따라 사용자가 레버(15a)를 간단히 조작할 수 있다. 가령, 커버플레이트(15b)에 형성되어 있는 가이드구멍(15c)을 따라 레버(15a)를 좌우로 재껴 조작하는 것이다.The cover plate 15b and the lever 15a constituting the electrode converter 15 are exposed to the outside of the casing 13 so that the user can simply operate the lever 15a according to the work. For example, the lever 15a is swept side to side along the guide hole 15c formed in the cover plate 15b.
한편, 상기 접지포트(17)와 토치접속포트(19)의 측부에는 표시부(21,23)가 위치하고 있다. 상기 표시부(21,23)에는 + 와 - 의 도형이 마킹되어 있으며 그 뒤에 램프(미도시)를 갖는다. 총 네 개의 램프가 설치되어 있는 것이다. On the other hand, the display portions 21 and 23 are located at the side portions of the ground port 17 and the torch connection port 19. The displays 21 and 23 are marked with figures + and-, and have a lamp (not shown) behind them. A total of four lamps are installed.
상기 램프는 선택적으로 점등되는 것으로서, 가령 접지포트(17)에 + 가 점등될 때 토치접속포트(19)에는 - 부분이 점등된다. 그 반대로 접지포트(17)에 - 가 점등될 때 토치접속포트(19)에는 + 가 점등된다.The lamp is selectively lit, for example, when the + is lit in the ground port 17, the − part is lit in the torch connecting port 19. FIG. On the contrary, when-is lit in the ground port 17, + is lit in the torch connection port 19.
이와같이, 각 접지포트(17)와 토치접속포트(19)에서 출력되는 전극의 점등 상태를 시각적으로 확인할 수 있으므로, 작업자는 물론 작업감독자나 기술지도자도 현재 올바른 전극의 전력이 공급되는지를 확인할 수 있다.In this way, since the lighting state of the electrodes output from each of the ground port 17 and the torch connection port 19 can be visually checked, not only an operator but also a work supervisor or a technical leader can confirm whether power of the correct electrode is currently supplied. .
상기 전극변환장치(15)의 세부 구성에 대해 도 2 내지 도 4를 통해 자세히 설명하면 다음과 같다.Detailed configuration of the electrode conversion device 15 will be described below with reference to FIGS. 2 to 4.
도 2는 상기 도 1에 도시한 전극변환장치(15)를 별도로 도시한 사시도이고, 도 3은 상기 전극변환장치(15)의 분해 사시도이다. 또한, 도 4는 상기 전극변환장치(15)를 다른 각도로 관찰한 도면이다.FIG. 2 is a perspective view separately showing the electrode converter 15 shown in FIG. 1, and FIG. 3 is an exploded perspective view of the electrode converter 15. As shown in FIG. 4 is a view of the electrode conversion device 15 observed at different angles.
도 2 내지 도 4를 참조하면, 상기 전극변환장치(15)는, 케이싱(13)의 내부에 고정되며 후술할 다수의 전극을 구비한 고정전극부(15k)와, 상기 고정전극부(15k)에 접한 상태로 사용자에 의해 좌우로 위치조절 가능한 이동전극부(15d)와, 상기 이동전극부(15d)를 고정전극부(15k)로부터 탄력적으로 이격시키는 탄성이격수단과, 상기 고정전극부(15k)를 커버하는 커버플레이트(15b)와, 상기 커버플레이트(15b)를 관통해 이동전극부(15d)에 연결되며 이동전극부(15d)를 좌우로 이동시키는 레버(15a)를 포함한다.2 to 4, the electrode converter 15 is fixed inside the casing 13 and includes a fixed electrode part 15k having a plurality of electrodes to be described later, and the fixed electrode part 15k. A movable electrode part 15d, which is positionally adjustable left and right by the user in contact with the elastic member, elastic separation means for elastically separating the moving electrode part 15d from the fixed electrode part 15k, and the fixed electrode part 15k. The cover plate (15b) and a lever (15a) is connected to the moving electrode portion 15d through the cover plate (15b) to move the moving electrode portion (15d) to the left and right.
먼저, 상기 고정전극부(15k)는, 케이싱(13) 내에 볼팅 결합되며 그 중앙부에 지지장공(15s)을 갖는 고정바디(15m)와, 상기 지지장공(15s)의 상부에 일직선상으로 배치되는 제 1상부전극(15p1)과 제 1중간전극(15t1)과 제 2상부전극(15q1)과, 상기 지지장공(15s)의 하부에 일직선상으로 위치하는 제 1하부전극(15p2)과 제 2중간전극(15t2)과 제 2하부전극(15q2)을 포함한다.First, the fixed electrode part 15k is bolted and coupled to the casing 13 and has a support body 15m having a support hole 15s at the center thereof, and is disposed in a straight line on an upper portion of the support hole 15s. The first upper electrode 15p1, the first intermediate electrode 15t1, the second upper electrode 15q1, the first lower electrode 15p2, and the second intermediate electrode positioned in a line below the support hole 15s. An electrode 15t2 and a second lower electrode 15q2 are included.
상기 고정바디(15m)는 절연재로 성형된 것으로서 상하단부에 두 개씩의 핀수용홈(15n)을 갖는다. 상기 핀수용홈(15n)은 일정간격을 갖는 홈이며, 후술할 스토퍼핀(15f)를 그 내부에 수용 지지한다.The fixed body 15m is formed of an insulating material and has two pin receiving grooves 15n at the upper and lower ends thereof. The pin receiving groove 15n is a groove having a predetermined interval, and accommodates and supports the stopper pin 15f to be described later.
한편, 상기 이동전극부(15d)는, 대략 블록의 형태를 취하며 중앙부에 관통구멍(15e)을 갖는 이동바디(15h)와, 상기 이동바디(15h)에 고정되는 것으로서 관통구멍(15e)의 상부에 위치하는 상부이동전극(15g1)과, 관통구멍(15e)의 하부에 구비되는 하부이동전극(15g2)을 포함한다.On the other hand, the moving electrode portion 15d has a shape of a block and is fixed to the moving body 15h having a through hole 15e in the center and the moving body 15h. And an upper movable electrode 15g1 disposed above and a lower movable electrode 15g2 provided below the through hole 15e.
상기 상부이동전극(15g1)은 도 4에 도시한 바와같이, 고정전극부(15k)의 제 1상부전극(15p1), 제 1중간전극(15t1), 제 2상부전극(15q1)과 마주하며 좌우로 이동 가능하다. 마찬가지로 하부이동전극(15g2)는 고정전극부(15k)의 제 1하부전극(15p2), 제 2중간전극(15t2), 제 2하부전극(15q2)과 마주하며 좌우로 이동하여 선택적 접속을 이룬다.As shown in FIG. 4, the upper movable electrode 15g1 faces the first upper electrode 15p1, the first intermediate electrode 15t1, and the second upper electrode 15q1 of the fixed electrode part 15k. It is possible to move to. Similarly, the lower movable electrode 15g2 faces the first lower electrode 15p2, the second intermediate electrode 15t2, and the second lower electrode 15q2 of the fixed electrode unit 15k to move left and right to form a selective connection.
또한 상기 이동바디(15h)의 상하단부에는 스토퍼핀(15f)이 고정되어 있다. 상기 스토퍼핀(15f)은 동일축선상에 위치하는 환봉형 부재로서, 상기 고정바디(15m)의 핀수용홈(15n)에 끼워져 지지된다. 상기 핀수용홈(15n)에 끼워진 상태의 스토퍼핀(15f)은 핀수용홈(15n) 내에 갇힌 상태로 측방향으로 움직이지 못한다. 즉, 좌우로 이동하지 못하는 것이다. 스토퍼핀(15f)의 작용으로 이동전극부(15d)의 측방향 이동이 방지되어 그만큼 안전하다.A stopper pin 15f is fixed to the upper and lower ends of the movable body 15h. The stopper pin 15f is an annular member located on the same axis and is supported by being fitted into the pin receiving groove 15n of the fixed body 15m. The stopper pin 15f in a state of being fitted into the pin receiving groove 15n does not move laterally in a state trapped in the pin receiving groove 15n. That is, it cannot move from side to side. The lateral movement of the moving electrode portion 15d is prevented by the action of the stopper pin 15f, which is safe.
스토퍼핀(15f)이 핀수용홈(15n)의 외부로 나온상태에서는 이동전극부(15d)의 측방향 이동 즉 좌우 이동이 가능함은 물론이다. In the state where the stopper pin 15f extends out of the pin receiving groove 15n, the moving electrode part 15d can be moved laterally, that is, left and right.
상기 커버플레이트(15b)는 중앙부에 가이드구멍(15c)을 갖는 판상부재로서 상기 이동전극부(15d)를 사이에 두고 고정전극부(15k)와 결합한다. 상기한 바와같이 커버플레이트(15b)는 통합용접기(11)의 케이싱(13) 외부로 노출되는 부분이다.The cover plate 15b is a plate member having a guide hole 15c in the center thereof, and is coupled to the fixed electrode part 15k with the moving electrode part 15d therebetween. As described above, the cover plate 15b is a part exposed to the outside of the casing 13 of the integrated welder 11.
아울러 상기 레버(15a)는 다이얼형 손잡이로서 상기 가이드구멍(15c)을 통해 상기한 탄성이격수단과 결합한다.In addition, the lever (15a) is a dial-type handle is coupled to the elastic separation means through the guide hole (15c).
상기 탄성이격수단은, 수나사봉(15u)과, 상기 수나사봉(15u)의 후단부에 고정되는 걸림부재(15w)와, 상기 걸림부재(15w)에 지지됨과 아울러 수나사봉(15u)을 감싸는 스프링(15v)으로 구성된다.The elastic separation means includes a male threaded rod 15u, a locking member 15w fixed to the rear end of the male threaded rod 15u, and a spring that is supported by the locking member 15w and surrounds the male threaded rod 15u. It consists of 15v.
상기 수나사봉(15u)은, 지지장공(15s)과 관통구멍(15e)을 통과한 후 레버(15a)와 나사 결합한다. 레버(15a)에 상기 수나사봉(15u)과 결합하는 암나사구(미도시)가 형성되어 있어야 함은 물론이다.The male threaded rod 15u is screwed with the lever 15a after passing through the support hole 15s and the through hole 15e. It is a matter of course that a female threaded ball (not shown) is formed in the lever 15a to be coupled to the male threaded rod 15u.
또한 상기 스프링(15v)은 지지장공(15s)을 통과하여 이동바디(15h)에 접한다. 즉, 스프링(15v)의 일단부는 이동바디(15h)에 접하고 타단부는 걸림부재(15w)에 접하는 것이다. 아울러 상기 걸림부재(15w)는 지지장공(15s)의 내주면에 형성되어 있는 걸림턱(미도시)에 걸려 지지된다. 도면부호 15x는 걸림부재(15w)를 커버하는 내측커버이다.In addition, the spring (15v) is in contact with the moving body (15h) through the support long hole (15s). That is, one end of the spring 15v is in contact with the moving body 15h and the other end is in contact with the locking member 15w. In addition, the locking member (15w) is supported by the locking jaw (not shown) formed on the inner peripheral surface of the support hole (15s). Reference numeral 15x denotes an inner cover that covers the locking member 15w.
상기 관통구멍(15e)의 외부로 노출된 수나사봉(15u)에 레버(15a)가 나사 결합한 상태에서 레버(15a)을 시계방향으로 돌리면, 수나사봉(15u)과 걸림부재(15w) 조립체가 스프링(15v)을 압축시키며 레버(15a)측으로 이동한다. 레버(15a)와 걸림부재(15w)의 간격이 점차 줄어드는 것이다.When the lever 15a is turned clockwise while the lever 15a is screwed to the male screw rod 15u exposed to the outside of the through hole 15e, the male screw rod 15u and the locking member 15w assembly spring. Compresses 15v and moves to the lever 15a side. The gap between the lever 15a and the locking member 15w gradually decreases.
레버(15a)를 더욱 회전시키면 마침내 걸림부재(15w)가 지지장공(15s)에 걸려 더 이상 이동하지 못하게 되고, 그 후에는 이동전극부(15d)가 움직이기 시작한다. 즉 이동전극부(15d)가 레버(15a)에 밀리며 스프링(15v)을 압축하면서 고정바디(15m)에 밀착하게 되는 것이다. 이 때 스토퍼핀(15f)이 일측 핀수용홈(15n)에 진입함은 물론이다.When the lever 15a is further rotated, the locking member 15w is finally caught by the support hole 15s and no longer moves, and then the moving electrode portion 15d starts to move. In other words, the moving electrode part 15d is pushed by the lever 15a and is pressed against the fixed body 15m while compressing the spring 15v. At this time, the stopper pin 15f enters the one side pin receiving groove 15n.
레버(15a)를 반대방향으로 회전시키면 스프링(15v)이 팽창하며, 이동전극부(15d)가 고정전극부(15k)로부터 벌어진다. 접속이 차단되는 것이다.When the lever 15a is rotated in the opposite direction, the spring 15v expands, and the moving electrode portion 15d is opened from the fixed electrode portion 15k. The connection is blocked.
한편, 상기 6개의 전극에 전력선을 연결하는 방식은 두 가지 회로구성 방식으로 구현될 수 있다.Meanwhile, the method of connecting the power lines to the six electrodes may be implemented in two circuit configurations.
첫 째 방식은, 제 1중간전극(15t1)에 토치접속포트(19), 제 2중간전극(15t2)에 접지포트(17)를 연결하고, 제 1상부전극(15p1) 및 제 2하부전극(15q2)에는 양극전류를 공급선을, 제 1하부전극(15p1) 및 제 2상부전극(15q1)에는 음극전류 공급선을 연결하는 것이다.In the first method, the torch connecting port 19 is connected to the first intermediate electrode 15t1 and the ground port 17 is connected to the second intermediate electrode 15t2, and the first upper electrode 15p1 and the second lower electrode ( An anode current supply line is connected to 15q2), and a cathode current supply line is connected to the first lower electrode 15p1 and the second upper electrode 15q1.
양극전류공급선이나 음극전류공급선은, 외부로부터 통합용접기(11) 내부로 인가된 교류전력을 직류로 변환 한 후의 양극전류와 음극전류를 공급하는 전력선이다. 이러한 양극전류공급선과 음극전류공급선은 보통의 용접기에 구비된 것과 같은 것이다.The positive electrode current supply line or the negative electrode current supply line is a power line for supplying the positive and negative currents after converting the AC power applied from the outside into the integrated welder 11 into direct current. These anode current supply lines and cathode current supply lines are the same as those provided in ordinary welding machines.
두 번째 방식은, 상기 제 1상부전극(15p1) 및 제 2하부전극(15q2)을 토치접속포트(19)에 연결하고, 제 1하부전극(15p2) 및 제 2상부전극(15q1)을 접지포트(17)에 연결하고, 제 1중간전극(15t1)에 양극전류공급선, 제 2중간전극(15t2)에 음극전류공급선을 연결하는 방식이다.In the second method, the first upper electrode 15p1 and the second lower electrode 15q2 are connected to the torch connection port 19, and the first lower electrode 15p2 and the second upper electrode 15q1 are grounded. And a cathode current supply line to the first intermediate electrode 15t1 and a cathode current supply line to the second intermediate electrode 15t2.
상기 첫 번째 방식을 취할지 두 번째 방식을 취할지는 사용자에 의해 결정된다.The first or second approach is determined by the user.
도 5a 및 도 5b는 상기 전극변환장치(15)의 작동을 설명하기 위한 도면이다. 각 전극이 위의 첫 번 째 방식으로 접속되어 있다는 전제로 설명하면 다음과 같다.5A and 5B are diagrams for explaining the operation of the electrode converter 15. The following description is based on the premise that each electrode is connected in the first manner.
도 5a를 참조하면, 상기 상부이동전극(15g1)이 제 1중간전극(15t1)과 제 2상부전극(15q1)을, 하부이동전극(15g2)이 제 2중간전극(15t2)과 제 2하부전극(15q2)를 접속시키고 있음을 알 수 있다.Referring to FIG. 5A, the upper movable electrode 15g1 includes the first intermediate electrode 15t1 and the second upper electrode 15q1, and the lower movable electrode 15g2 includes the second intermediate electrode 15t2 and the second lower electrode. It turns out that (15q2) is connected.
이 상태에서는 상기 제 1중간전극(15t1)에 마이너스전류가, 제 2중간전극(15t2)에 플러스전류가 인가된다. 토치접속포트(19)에 마이너스전류, 접지포트(17)에 플러스전류가 공급되는 것이다. TIG용접에 적합한 상태이다. 이 때 표시부(21)에는 + 부분이 점등되고, 표시부(23)에는 - 부분에 불이들어온다.In this state, a negative current is applied to the first intermediate electrode 15t1 and a positive current is applied to the second intermediate electrode 15t2. The negative current is supplied to the torch connection port 19 and the positive current is supplied to the ground port 17. It is suitable for TIG welding. At this time, the + part is turned on in the display unit 21, and the − part is lit in the display unit 23.
상기 상태에서 출력전극을 전환하고자 한다면, 상기 레버(15a)를 반시계방향으로 풀어 스토퍼핀(15f)이 핀수용홈(15n)으로부터 빠져나오게 한 상태로 레버(15a)를 도면상 좌측방향으로 이동시킨다.If the output electrode is to be switched in this state, the lever 15a is released counterclockwise to move the lever 15a to the left in the drawing in a state in which the stopper pin 15f is released from the pin receiving groove 15n. Let's do it.
레버(15a)를 상기와 같이 이동시켜, 도 5b에 도시한 바와같이 상부이동전극(15g1)이 제 1상부전극(15p1) 및 제 1중간전극(15t1)을, 하부이동전극(15g2)이 제 1하부전극(15p2) 및 제 2중간전극(15t2)을 접속한다면, 이번에는 토치접속포트(19)에 마이너스전류가, 접지포트(17)에 플러스전류가 인가된다. MIG용접이나 CO2용접을 할 수 있는 상태로 변환된 것이다.The lever 15a is moved as described above, and as shown in FIG. 5B, the upper movable electrode 15g1 serves as the first upper electrode 15p1 and the first intermediate electrode 15t1, and the lower movable electrode 15g2 as the first movable electrode 15g1. If the first lower electrode 15p2 and the second intermediate electrode 15t2 are connected, a negative current is applied to the torch connection port 19 and a positive current is applied to the ground port 17 at this time. It is converted into a state capable of MIG welding or CO2 welding.
상기한 두 번째 방식의 회로구성이 되었을 때는 다음과 같이 작동한다.When the circuit configuration of the second method described above is achieved, it operates as follows.
도 5a에 도시한 바와같이, 상부이동전극(15g1)으로 제 1중간전극(15t1) 및 제 2상부전극(15q1)을, 하부이동전극(15g2)으로 제 2중간전극(15t2)과 제 2하부전극(15q2)을 접속시키면, 플러스전류가 제 2상부전극(15q1)을 통해 접지포트(17)로 인가되고, 마이너스전류가 제 2하부전극(15q2)를 거쳐 토치접속포트(19)로 공급된다. TIG용접에 적합한 회로구성이 이루어진 것이다.As shown in FIG. 5A, the first intermediate electrode 15t1 and the second upper electrode 15q1 are used as the upper movable electrode 15g1, and the second intermediate electrode 15t2 and the second lower portion are used as the lower movable electrode 15g2. When the electrode 15q2 is connected, a positive current is applied to the ground port 17 through the second upper electrode 15q1, and a negative current is supplied to the torch connection port 19 via the second lower electrode 15q2. . The circuit configuration suitable for TIG welding is made.
이 상태에서, 상기 이동전극부(15d)를 조작하여 도 5b에 도시한 상태로 전환하면, 플러스전류가 제 1상부전극(15p1)을 통해 토치접속포트(19)로, 마이너스전류가 제 1하부전극(15p2)를 거쳐 접지포트(17)로 인가된다. 이러한 회로구성은 MIG용접이나 CO2용접에 사용할 수 있는 상태이다.In this state, when the moving electrode unit 15d is operated to switch to the state shown in FIG. 5B, a positive current flows through the first upper electrode 15p1 to the torch connection port 19, and a negative current is applied to the first lower portion. It is applied to the ground port 17 via the electrode 15p2. This circuit configuration can be used for MIG welding or CO2 welding.
결국 상기한 바와같이, 구성되는 본 실시예에 따른 전극변환장치(15)는 간단한 조작만으로 출력전류의 극성을 전환할 수 있어 그만큼 사용이 편리하다. As a result, as described above, the electrode conversion device 15 according to the present embodiment can be configured to switch the polarity of the output current with a simple operation, and thus it is convenient to use.
이하, 본 발명에 따른 하나의 실시예를 첨부된 도 6과 7을 참조하여 보다 상세히 설명하기로 한다.Hereinafter, one embodiment according to the present invention will be described in more detail with reference to FIGS. 6 and 7.
기본적으로 본 실시예에 따른 용접토치헤드 냉각 및 용접흄 처리장치는, 용접용 전원장치에 연결하여 사용하는 용접용 토치헤드를 냉각하기 위한 것이다. Basically, the welding torch head cooling and welding fume treatment apparatus according to the present embodiment is for cooling the welding torch head used in connection with a welding power supply.
상기 용접토치헤드는 용접 작업시 매우 높은 온도로 가열되므로 냉각이 중요한데, 본 실시예의 경우, 용접토치헤드의 주변에 공기의 흐름을 야기하여 냉각을 수행한다. Since the welding torch head is heated to a very high temperature during a welding operation, cooling is important. In this embodiment, cooling is performed by causing air to flow around the welding torch head.
즉, 보통, 용접케이블에 묶여 있는 에어케이블을 통해 공기를 용접토치헤드 측으로 분출하여 토치헤드를 냉각하거나, 용접토치헤드 주변에 머물러 있는 공기를 흡기함으로써 새로운 공기가 토치헤드를 감싸도록 유도하여 냉각을 도모하는 것이다. In other words, the air is bound to the welding torch head through the air cable tied to the welding cable to cool the torch head, or by inhaling air remaining around the welding torch head to induce new air to surround the torch head. It is to plan.
특히 공기의 흡기시 용접헤드 부근에서 발생하는 용접흄까지 흡기하여 처리할 수 있어 일석이조의 효과를 제공한다. 참고로, 상기 용접흄은 용접시 발생하는 유독성 기체로서 중금속을 포함하므로 체내에 축척될 경우 암은 물론 각종 질환을 일으킬 수 있다.In particular, the welding fumes generated near the welding head during the intake of air can be inhaled and treated to provide the effect of two-season tanks. For reference, the welding fume includes heavy metals as toxic gases generated during welding, and when accumulated in the body, cancer may cause various diseases as well.
도 6은 본 발명의 일 실시예에 따른 용접토치헤드 냉각 및 용접흄 처리장치의 구성을 설명하기 위한 절제 사시도이다.6 is a cutaway perspective view for explaining the configuration of the welding torch head cooling and welding fume treatment apparatus according to an embodiment of the present invention.
도시한 바와같이, 본 실시예에 따른 용접토치헤드 냉각 및 용접흄 처리장치는, 용접용 전원장치(11)의 케이싱(13) 내부에 설치된다. 상기 용접용 전원장치(11)는 박스의 형태를 취하며 그 일측에 제어패널(15)을 가지며 용접에 필요한 전력이나 제어신호를 출력하는 역할을 한다.As shown, the welding torch head cooling and welding fume processing apparatus according to the present embodiment is installed inside the casing 13 of the welding power supply device 11. The welding power supply 11 takes the form of a box and has a control panel 15 on one side thereof, and serves to output power or control signals required for welding.
상기 제어패널(15)에는 에어케이블(미도시)이 접속되는 에어연결구(17)와 제어부(43)와 전환스위치(19)가 설치된다. 상기 에어연결구(17)에 접속되는 에어케이블은 그 내부에 공기통로가 마련되어 있는 케이블로서 단부가 용접토치를 향하도록 고정된다.The control panel 15 is provided with an air connector 17 to which an air cable (not shown) is connected, a control unit 43, and a switching switch 19. The air cable connected to the air connector 17 is a cable having an air passage therein, and is fixed at an end thereof toward the welding torch.
따라서 가령 상기 에어연결구(17)를 통해 공기를 토출하면 토출된 공기는 에어케이블을 길이방향으로 통과하여 용접토치(미도시)에 도달하게 된다. 용접토치에 도달한 공기는 에어케이블의 단부로 부터 토출되며 용접토치를 냉각한다.Therefore, for example, when the air is discharged through the air connector 17, the discharged air passes through the air cable in the longitudinal direction to reach a welding torch (not shown). The air reaching the welding torch is discharged from the end of the air cable and cools the welding torch.
또한 케이싱(13) 내부에서 에어연결구(17)를 통해 진공압력을 제공하면, 용접토치 주변의 공기가 에어케이블의 단부로 유입하여 에어연결구(17)까지 끌려 들어온다. 특히 용접시 발생하는 용접토치 주변의 용접흄도 함께 흡기된다.In addition, when the vacuum pressure is provided through the air connector 17 inside the casing 13, air around the welding torch flows into the end of the air cable and is drawn into the air connector 17. In particular, the welding fumes around the welding torch generated during welding are also taken in.
상기 제어부(43)는 후술할 에어펌프(33)와 밸브(23)를 제어하는 콘트롤러로서, 전환스위치(19)의 조작에 따른 제어신호를 출력한다. 전환스위치(19)를 통해 밸브(23)와 에어펌프(33)의 작동을 조절할 수 있는 것이다.The controller 43 is a controller for controlling the air pump 33 and the valve 23 to be described later, and outputs a control signal according to the operation of the changeover switch 19. It is possible to control the operation of the valve 23 and the air pump 33 through the switch 19.
여하튼, 본 실시예에 따른 냉각 및 용접흄 처리장치는, 상기 케이싱(13)의 내부공간(21)에 설치되며 외부로부터 인가된 전력에 의해 작동하는 에어펌프(33)와, 상기 에어펌프(33)와 접속되며 제1,2,3,4,5포트(23a,23b,23c,23d,23e)를 가지는 밸브(23)와, 상기 밸브(23)의 제 5포트(23e)를 에어연결구(17)과 연결시키는 접속튜브(35)와, 상기 제 1포트(23a) 및 제 2포트(23b)를 에어펌프(33)의 입구 및 출구에 각각 연통시키는 제 1중간튜브(29) 및 제 2중간튜브(31)와, 전원장치(11) 외부의 공기를 제 3포트(23c)로 유도하는 외기도입튜브(25)와, 상기 제 4포트(23d)와 연결되며 제 4포트(23d)를 통해 배출되는 유체를 대기중으로 방출하는 배출튜브(27) 등을 포함한다.In any case, the cooling and welding fume treatment apparatus according to the present embodiment, the air pump 33 is installed in the inner space 21 of the casing 13 and operated by electric power applied from the outside, and the air pump 33 And a valve 23 having first, second, second, third, fourth and fifth ports 23a, 23b, 23c, 23d and 23e, and the fifth port 23e of the valve 23 to the air connector 17. A first intermediate tube (29) and a second intermediate tube (35) for connecting the first tube (23a) and the second port (23b) to the inlet and outlet of the air pump (33), respectively. A tube 31, an external air intake tube 25 that guides air outside the power supply 11 to the third port 23c, and is connected to the fourth port 23d and through the fourth port 23d. And a discharge tube 27 for discharging the discharged fluid into the atmosphere.
상기 에어펌프(33)는, 통상의 에어펌프가 그러하듯이 입구와 출구를 갖는다. 후술하는 설명에서의 입구는 펌핑할 공기가 들어오는 통로이고, 출구는 펌핑된 공기가 토출되는 통로이다.The air pump 33 has an inlet and an outlet as is a normal air pump. In the following description, the inlet is a passage through which air to be pumped comes in, and the outlet is a passage through which pumped air is discharged.
상기 에어펌프(33)는 케이싱(13)의 바닥부(37)에 고정된 상태로 제어부(43)의 제어신호에 따라 작동하며 유체를 펌핑한다. 상기 에어펌프가 펑핑하는 대상은 케이싱(13) 외부로부터 흡기되어 용접토치로 제공될 냉각용 공기이거나, 용접토치로부터 흡기된 용접흄을 포함한 오염된 가스이다. The air pump 33 operates in accordance with the control signal of the control unit 43 while being fixed to the bottom 37 of the casing 13 and pumps the fluid. The object to which the air pump is punctured is cooling air to be intaken from the outside of the casing 13 and provided to the welding torch, or a contaminated gas including the welding fume sucked from the welding torch.
또한 상기 밸브(23)는 케이싱(13)의 벽부에 고정된 전자밸브로서 제 1,2중간튜브(29,31)를 통해 에어펌프(33)와 접속된다.In addition, the valve 23 is an electromagnetic valve fixed to the wall of the casing 13 and is connected to the air pump 33 through the first and second intermediate tubes 29 and 31.
도시한 바와같이, 상기 밸브(23)는 일측부에 제 1포트(23a)및 제 2포트(23b)를 가지고, 그 반대편에 제 3포트(23c)와 제 4포트(23d)와 제 5포트(23e)를 구비한다. 상기 각 포트는 밸브(23)의 내부에 마련된 유로에 의해 접속된다.As shown, the valve 23 has a first port 23a and a second port 23b on one side thereof, and a third port 23c, a fourth port 23d, and a fifth port on opposite sides thereof. 23e is provided. Each port is connected by a flow path provided inside the valve 23.
구체적으로, 상기 제 1포트(23a)는 제 3포트(23c) 또는 제 5포트(23e)와 선택적으로 접속 가능하다. 또한, 제 2포트(23b)는 제 5포트(23e) 또는 제 4포트(23d)와 접속 가능하다. 본 설명에서의 접속한다는 용어의 의미는 연통한다는 의미이다. 즉 유체가 통과할 수 있는 통로가 만들어진다는 뜻이다.Specifically, the first port 23a may be selectively connected to the third port 23c or the fifth port 23e. In addition, the second port 23b can be connected to the fifth port 23e or the fourth port 23d. In this description, the term "connecting" means communicating. This means that a passage through which the fluid can pass is created.
특히, 상기 제 1포트(23a)가 제 3포트(23c)와 접속할 때, 제 2포트(23b)는 제 5포트(23e)와 접속을 이룬다. 이 때 제 4포트(23d)는 차단된다.In particular, when the first port 23a is connected to the third port 23c, the second port 23b is connected to the fifth port 23e. At this time, the fourth port 23d is blocked.
또한 제 1포트(23a)가 제 5포트(23e)와 접속될 때, 제 2포트(23b)는 제 4포트(23d)와 접속하고 제 3포트(23c)는 차단된다.When the first port 23a is connected to the fifth port 23e, the second port 23b is connected to the fourth port 23d and the third port 23c is blocked.
이와같은 유로의 선택적 접속과 차단 동작은 보통의 밸브가 갖는 기본 기능으로서 전환스위치(19)에 의해 구현된다. 상기 밸브로서 솔레노이드밸브 또는 이와 유사한 수동밸브를 적용할 수 있다.Such a selective connection and disconnection operation of the flow path is implemented by the changeover switch 19 as a basic function of a normal valve. As the valve, a solenoid valve or a similar manual valve may be applied.
상기 전환스위치(19)는 세 가지 모드의 운전을 구현할 수 있다. 이를테면 에어연결구(17)를 통해 냉각용 공기를 내보내는 토출모드와, 에어펌프(33)를 정지시키는 정지모드와, 에어연결구(17)를 통해 외부의 공기를 케이싱(13) 외부로 끌어오는 흡기모드이다.The changeover switch 19 can implement three modes of operation. For example, a discharge mode for discharging cooling air through the air connector 17, a stop mode for stopping the air pump 33, and an intake mode for drawing external air to the outside of the casing 13 through the air connector 17 to be.
먼저, 상기 전환스위치(19)를 토출모드에 놓으면, 제어부(43)는 에어펌프(33)를 작동시킴과 아울러, 밸브(23)에 제어신호를 보내어, 상기 제 1포트(23a)와 제 3포트(23c), 제 2포트(23b)와 제 5포트(23e)를 접속시킨다.First, when the changeover switch 19 is placed in the discharge mode, the control unit 43 operates the air pump 33 and sends a control signal to the valve 23, thereby providing the first port 23a and the third port. The port 23c, the second port 23b and the fifth port 23e are connected.
상기한 유로패턴이 구현됨에 따라, 케이싱(13) 외부의 공기가 외기도입튜브(25)를 통해 케이싱(13)의 내부로 유입한다. 외기도입튜브(25)를 통해 들어온 공기는, 제 3포트(23c)와 밸브의 내부유로(미도시)를 거쳐 제 1포트(23a)를 통과한 후 제 1중간튜브(29)를 거쳐 에어펌프(33)의 입구로 빨려 들어간다.As the flow path pattern is implemented, air outside the casing 13 flows into the casing 13 through the outside air inlet tube 25. The air introduced through the external air inlet tube 25 passes through the first port 23a through the third port 23c and the internal flow path (not shown) of the valve, and then through the first intermediate tube 29, the air pump. It is sucked into the entrance of (33).
상기 에어펌프(33)를 통과하며 펌핑된 공기는, 에어펌프의 출구를 통해 배출되며, 제 2중간튜브(31)와 제 2포트(23b)와 제 5포트(23e)와 접속튜브(35)를 차례로 통과하여 에어연결구(17)를 통해 토출된다. 이 때 제 4포트(23d)는 차단되어 펌핑공기가 배출튜브(27)로 빠질 염려가 없다.The air pumped through the air pump 33 is discharged through an outlet of the air pump, and the second intermediate tube 31, the second port 23b, the fifth port 23e, and the connection tube 35 are provided. Passed through in order to be discharged through the air connector (17). At this time, the fourth port 23d is blocked so that the pumping air does not fall into the discharge tube 27.
여하튼 상기 에어연결구(17)를 통해 토출되는 공기는 에어연결구(17)을 물고 있는 에어케이블을 통과해 용접토치헤드에 도달한 후, 용접토치헤드를 냉각하며 대기중으로 흩어진다.In any case, the air discharged through the air connector 17 passes through the air cable holding the air connector 17 to reach the welding torch head, and then cools the welding torch head and is dispersed into the atmosphere.
전환스위치(19)를 정지모드에 놓으면 제어부(43)가 에어펌프(33)를 정지시켜 냉각을 위한 동작이 멈춘다. 용접작업을 하지 않을 때에는 전환스위치(19)를 정지모드에 놓아 전기에너지를 절약할 수 있다.When the changeover switch 19 is placed in the stop mode, the control unit 43 stops the air pump 33 to stop the operation for cooling. When the welding operation is not performed, the changeover switch 19 can be placed in the stop mode to save electrical energy.
또한 상기 전환스위치(19)를 흡기모드로 돌리면, 제어부(43)는 에어펌프(33)를 다시 가동시킴과 동시에, 제 1포트(23a)와 제 5포트(23e), 제 2포트(23b)와 제 4포트(23d)를 접속시킨다. 이와 동시에 제 3포트(23c)는 차단된다.When the selector switch 19 is turned to the intake mode, the control unit 43 starts the air pump 33 again, and at the same time, the first port 23a, the fifth port 23e, and the second port 23b. And the fourth port 23d are connected. At the same time, the third port 23c is blocked.
그 결과, 에어연결구(17) 외부의 공기는, 접속튜브(35)와 제 5포트(23e)와 제 1포트(23a)를 통과해 제 1중간튜브(29)를 거쳐 펌프의 입구로 들어간다. 상기 펌프의 입구로 들어온 공기는 제 2중간튜브(31)를 거쳐 제 2포트(23b)와 제 4포트(23d)를 통과해 배출튜브(27)를 통해 외부로 빠진다. 에어케이블 선단부 주변의 공기나 용접흄을 빨아들여 배출튜브(27)를 통해 배기하는 것이다.As a result, the air outside the air connector 17 passes through the connecting tube 35, the fifth port 23e, and the first port 23a, and enters the inlet of the pump via the first intermediate tube 29. Air entering the inlet of the pump passes through the second port (23b) and the second port (23b) and the fourth port (23d) is discharged to the outside through the discharge tube (27). Air or welding fumes around the end of the air cable to suck the exhaust through the discharge tube (27).
도 7은 용접토치헤드 냉각 및 용접흄 처리장치에 포함되는 분진제거필터(39) 및 유입에어필터(41)를 나타내 보인 도면이다.7 is a view showing the dust removal filter 39 and the inlet air filter 41 included in the welding torch head cooling and welding fume treatment apparatus.
상기 유입에어필터(41)는 외기도입튜브(25)의 단부에 고정된 필터로서, 유입에어필터(41)로 유입하는 공기를 통과시켜 불순물을 걸러내는 역할을 한다. 상기 유입에어필터(41)로서 소음기능을 갖는 스폰지 등을 적용할 수 있다. The inlet air filter 41 is a filter fixed to the end of the outside air inlet tube 25, and serves to filter the impurities by passing the air flowing into the inlet air filter 41. As the intake air filter 41, a sponge having a noise function, or the like may be applied.
또한, 분진제거필터(39)는 배출튜브(27)를 통해 배출되는 기체, 즉 용접흄이나 분진 등이 포함되어 있는 기체를 정화처리 하는 역할을 한다. 상기 분진제거필터(39)는 2단의 구조를 갖는다. In addition, the dust removal filter 39 serves to purify the gas discharged through the discharge tube 27, that is, the gas containing the welding fume or dust. The dust removal filter 39 has a two-stage structure.
일단은 일반적인 스폰지를 적용한 필터이며 이단은 알루미늄 발포제를 양극산화피막처리하여 알루미나 세라믹의 중공폴을 형성한 구조를 갖는 필터이다. 이러한 형태의 알루미나 세라믹 중공폴을 이용한 필터는 일정기간 사용 후 물로 다시 세척하여 다시 사용할 수 있다. One end is a filter applying a common sponge, and the second step is a filter having a structure in which a hollow pole of alumina ceramic is formed by anodizing an aluminum foaming agent. The filter using the alumina ceramic hollow pole of this type can be used again by washing again with water after a certain period of use.
결국 상기 분진제거필터(39)를 적용함으로서, 용접토치로부터 빨려 들어온 유독성 기체를 정화처리한 후 배출할 수 있는 것이다.Eventually, by applying the dust removal filter 39, it is possible to purify the toxic gas sucked from the welding torch and then discharged.
한편, 본 실시예에 따른 용접토치헤드 냉각 및 용접흄 처리장치는, 상기 에어펌프(33)를 양방향 방식으로 적용할 경우 보다 단순화 시킬 수 있다. 양방향 방식이라 함은, 제어부(43)의 작동에 의해, 에어펌프(33)의 흡기와 토출방향을 반대로 전환하는 것이다. 가령, 흡기포트를 통해 에어를 토출하고, 토출포트를 통해 에어를 흡기하는 것이다.On the other hand, the welding torch head cooling and welding fume treatment apparatus according to the present embodiment can be simplified when the air pump 33 is applied in a bidirectional manner. The bidirectional method is to reverse the intake and discharge directions of the air pump 33 by the operation of the control unit 43. For example, the air is discharged through the intake port, and the air is taken in through the discharge port.
이와같이, 양방향 방식의 에어펌프를 적용한다면, 상기 밸브(23)에는 외기도입튜브(23)와 배출튜브(27)와 접속튜브(35)만 장착되어도 된다. 경우에 따라 외기도입튜브(23)와 배출튜브(27)도 별도로 나누지 않고 하나로 사용할 수 있다. 그러나 유입에어필터(41)와 분진제거필터(39)의 고유한 기능을 고려할 때 외기도입튜브(23)와 배출튜브(27)를 따로 적용함이 좋다.As such, if the bidirectional air pump is applied, the valve 23 may be equipped with only the outside air inlet tube 23, the discharge tube 27, and the connection tube 35. In some cases, the external air inlet tube 23 and the discharge tube 27 may also be used as one without dividing. However, considering the inherent functions of the inlet air filter 41 and the dust removal filter 39, it is preferable to apply the air intake tube 23 and the discharge tube 27 separately.
이와 같이 구성된 상태에서, 토치헤드측으로 냉각용 공기를 공급하기 위해, 에어펌프로 하여금, 외기도입튜브(25)를 통해 외부의 공기를 흡기하여 에어연결구(17)를 통해 공기를 토출시키면 공기는 토치헤드측으로 이동하여 냉각을 수행한다.In this configuration, in order to supply cooling air to the torch head side, the air pump inhales the outside air through the outdoor air inlet tube 25 and discharges the air through the air connector 17. Move to the head side to perform cooling.
반대로 흄가스를 흡기하여 제거하고자 할 경우에는, 제어부(43)를 통해 에어펌프 내의 로터를 역회전시켜 에어펌프(33)로 하여금 토치헤드측의 흄가스를 흡기하도록 한다.On the contrary, if the fume gas is to be inhaled and removed, the rotor in the air pump is reversely rotated through the control unit 43 to allow the air pump 33 to inhale the fume gas on the torch head side.
상기 토치헤드측으로부터 흡기된 흄가스는 에어연결구(17)를 통해 접속튜브(35)를 거쳐 밸브(23)를 경유한 후 배출튜브(27)를 통해 빠져나간다. 이 때 상기 분진제거필터(39)에 의해 정화처리됨은 물론이다.The fume gas taken in from the torch head side passes through the valve 23 through the connection tube 35 through the air connector 17 and then exits through the discharge tube 27. At this time, of course, the dust removal filter 39 is purified.
이상, 본 발명을 구체적인 실시예를 통하여 상세하게 설명하였으나, 본 발명은 상기 실시예에 한정하지 않고, 본 발명의 기술적 사상의 범위내에서 통상의 지식을 가진 자에 의하여 여러 가지 변형이 가능하다.As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.
