Abstract

A torch head tip of a CO2 welding machine is provided, wherein the torch head tip enables a welding wire to be smoothly discharged to the outside without the welding wire being pressure-welded even when an end of a tip which is subject to a welding heat in the largest amount is expanded much by a high temperature. A torch head tip of a CO2 welding machine comprises: a torch head(1) to which a nozzle(2) is fixed, and in which a welding wire-guiding hole(101) is formed; and a tip(3) which is screwed to the torch head, and in which a welding wire-guiding hole(301) is formed, wherein a marginal space(3a) is formed in an end portion of the tip such that a diameter of the marginal space is larger than that of the welding wire-guiding hole to allow a welding wire(4) to move smoothly through the marginal space although the end portion of the tip is expanded.

이산화탄소용접기의 토치헤드팁{TORCH HEAD TIP OF CO2 GAS WELDING MACHINE}TORCH HEAD TIP OF CO2 GAS WELDING MACHINE}

도1은 본 발명의 바람직한 실시예의 단면도1 is a cross-sectional view of a preferred embodiment of the present invention.

도2는 종래의 토치헤드의 단면도2 is a cross-sectional view of a conventional torch head.

2. 노즐 3. 팁(TIP)2. Nozzle 3. Tip

301. 용접와이어안내구멍 3a. 여유공간홀301. Welding wire guide hole 3a. Free Space Hall

본 발명은 이산화탄소(CO2)가스의 고열에 의하여 용접와이어를 녹여 용접하는 이산화탄소용접기의 토치헤드팁에 관한 것으로서The present invention relates to a torch head tip of a carbon dioxide welding machine for melting and welding a welding wire by a high temperature of carbon dioxide (CO2) gas.

더욱 상세하게는 팁의 용접와이어안내구멍의 제일 끝 부위에 용접와이어안내구멍의 구경보다 넓게 여유공간홀을 형성하여 3600도의 높은 용접 열에 팁의 끈이 팽창되는 것에 의하여 용접와이어안내구멍이 수축되어 용접와이어가 압접되는 것을 방지할 수 있도록 한 것이다.More specifically, at the end of the welding wire guide hole of the tip, a clearance hole is formed wider than the diameter of the welding wire guide hole, and the welding wire guide hole is contracted by the expansion of the string of the tip in the high welding heat of 3600 degrees. It is to prevent the wire from being pressed.

용접 시에 용접부와 아주 가까운 20mm거리를 유지하는 팁의 끝 부분은 3600도의 높은 용접 간접열을 제일 많이 받게 됨과 동시에 다른 팁 부위에 비하여 팽창도 많이 되고 팽창에 비례하여 용접와이어구멍은 많이 수축되는바,The tip of the tip, which maintains a distance of 20mm very close to the welding part, receives the highest welding indirect heat of 3600 degrees, and also expands more than other tip areas, and the welding wire hole contracts in proportion to the expansion. ,

종래의 토치헤드(1)의 팁(3)의 용접와이어안내구멍(301)은 도2에 도시한 바와 같이 전체가 동일 직경으로 되었기 때문에 용접 시 용접 열을 제일 많이 받아 다른 부위보다 팽창이 많이 되는 팁(3)의 끝 부분은 팽창에 의하여 용접와이어안내구멍(301)은 좁혀져 용접와이어(4)는 압접된다.Since the welding wire guide hole 301 of the tip 3 of the conventional torch head 1 has the same diameter as shown in FIG. 2, the welding wire guide hole 301 receives the welding heat the most during welding and expands more than other parts. As the end of the tip 3 is expanded, the welding wire guide hole 301 is narrowed so that the welding wire 4 is press-contacted.

이에 따라 용접와이어(4)는 외부로 배출이 원활하게 이루어 지지 못하여 팽창이 많이 되었을 때는 팁(3)을 냉각시켜 가며 용접해야 됨으로 용접작업효율이 매우 저조한 문제가 따르게 되었다.Accordingly, the welding wire (4) is not discharged to the outside smoothly, when the expansion was a lot of the tip (3) to be cooled and welded, so the welding work efficiency was very poor problem.

본 발명은 상기와 같은 문제점을 해결하기 위하여The present invention to solve the above problems

노즐(2)이 고정되고 용접와이어안내구멍(101)을 형성한 토치헤드(1)에 용접와이어안내구멍(301)을 형성한 팁(3)을 나사고정 하여서 된 것에 있어서In the case where the nozzle 2 is fixed and the tip 3 having the welded wire guide hole 301 is screwed into the torch head 1 having the welded wire guide hole 101.

팁(3)의 끝 부위에는 용접와이어안내구멍(301)의 직경보다 넓은 여유공간홀(3a)을 형성하여 용접 열을 제일 많이 받은 팁(3)의 끝이 고열에 의하여 많이 팽창될 시에도 용접와이어(4)는 압접됨이 없이 외부로 원활하게 배출시킬 수 있도록 한 이산화탄소용접기의 토치헤드팁을 제공할 수 있도록 한 것에 그 목적이 있다.In the tip portion of the tip 3, a clearance hole 3a wider than the diameter of the welding wire guide hole 301 is formed to weld even when the tip 3, which receives the most welding heat, is expanded due to high heat. The purpose of the wire 4 is to provide a torch head tip of the carbon dioxide welder that can be smoothly discharged to the outside without being pressed.

이하 본 발명을 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명의 바람직한 실시예의 단면도 로서1 is a cross-sectional view of a preferred embodiment of the present invention.

도1에 도시한 바와 같이As shown in FIG.

노즐(2)이 고정되고 용접와이어안내구멍(101)을 형성한 토치헤드(1)에 용접와이어안내구멍(301)을 형성한 팁(3)을 나사고정 하여서 된 것에 있어서In the case where the nozzle 2 is fixed and the tip 3 having the welded wire guide hole 301 is screwed into the torch head 1 having the welded wire guide hole 101.

팁(3)의 끝 부위에는 용접와이어안내구멍(301)의 직경보다 넓은 여유공간홀(3a)을 형성하여 팽창 시에도 용접와이어(4)의 이동이 원활하게 이루어지도록 한 것을 특징으로 한다.An end portion of the tip 3 is formed with a free space hole 3a wider than the diameter of the welded wire guide hole 301 to smoothly move the welded wire 4 even when inflated.

미설명부호 102는 가스분사구멍 이다.Reference numeral 102 is a gas injection hole.

이와 같이 된 본 발명은 토치헤드(1)의 용접와이어안내구멍(101)과 팁(3)의 용접와이어안내구멍(301)을 통하여 외부로 배출되는 용접와이어(4)을 가스분사구멍(102)으로 분사되는 이산화탄소가스의 연소열에 의하여 용접와이어(4)을 용융시켜 용접하게 되는 것은 종래와 동일하다.According to the present invention, the welding wire 4 discharged to the outside through the welding wire guide hole 101 of the torch head 1 and the welding wire guide hole 301 of the tip 3 has a gas injection hole 102. The welding wire 4 is melted and welded by the combustion heat of carbon dioxide gas injected into the same as in the related art.

상기에 있어서 본 발명은 용접부와 제일 가까워 용접고열을 많이 받아 팽창이 제일 많이 이루어지는 팁(3)의 용접와이어안내구멍(301)의 끝 부분에는 용접와이어안내구멍(301)보다 넓은 여유공간홀(3a)을 형성하였으므로 팁(3)의 끝 부분이 용접 열에 의하여 도 1의 원형 내의 여유공간홀(3a)에 점선표시와 같이 많이 팽창 될 시에도 종래와는 달리 팽창되는 팁(3)에 의하여 용접와이어(4)은 압접되지 않는다.In the above, the present invention is the closest to the weld portion, the end of the welding wire guide hole 301 of the tip (3), which receives a lot of welding high heat and expands the most, the free space hole (3a) wider than the weld wire guide hole (301) Since the end portion of the tip 3 is expanded in the free space hole 3a in the circle of FIG. (4) is not pressed.

이에 따라 팁(3)의 끝이 팽창될 시에도 용접와이어(4)는 원활하게 외부로 이동하게 되므로 종래처럼 수시로 냉각시키지 않고 오랜 시간 용접작업을 행할 수 있게 되어 용접작업효율을 향상시킬 수 있다.Accordingly, even when the tip 3 is inflated, the welding wire 4 smoothly moves to the outside, so that welding work can be performed for a long time without cooling from time to time as in the prior art, thereby improving welding work efficiency.

그리고 본 발명은 도면과 설명에 한정되는 것이 아니고 요지를 벗어나지 않는 범위 내에서 변화시킬 수 있다.In addition, the present invention is not limited to the drawings and the description, and may be changed without departing from the gist of the invention.

이와 같은 본 발명은 팁(3)의 끝 부위에는 용접와이어안내구멍(301)보다 넓은 여유공간홀(3a)을 형성하여 용접 열을 제일 많이 받은 팁(3)의 끝이 고열에 의하여 많이 팽창될 시에도 용접와이어(4)가 압접되는 것을 방지할 수 있도록 하였으므로 용접와이어(4)의 원활한 이동에 의하여 오랜 시간 용접작업을 행할 수 있게 되어 용접작업효율을 향상시킬 수 있는 효과가 있다.In the present invention as described above, the tip portion of the tip 3 is formed with a wider space hole 3a wider than the weld wire guide hole 301, so that the tip of the tip 3 that receives the most welding heat is expanded by high heat. Since the welding wire 4 can be prevented from being pressed at the time, the welding wire 4 can be welded for a long time by the smooth movement of the welding wire 4, thereby improving the welding work efficiency.
