Description

용접비이드 형성방지용 냉각로울러Cooling Roller to Prevent Weld Bead Formation

제 1 도는 본 고안의 전체 사시도.1 is an overall perspective view of the present invention.

제 2 도는 본 고안의 요부 절개단면도.2 is a cross-sectional view of the main part of the present invention.

제 3 도는 본 고안의 실시 상태도.3 is an embodiment of the present invention.

제 4a 도는 본 고안 실시예에 의한 파이프의 용접 단면도이며, (b) 도는 종래 파이프의 용접단면도 임.Figure 4a is a sectional view of the welded pipe according to the embodiment of the present invention, (b) is a sectional view of a conventional pipe welded.

본 고안은 강철파이프나, 스텐레스파이프 또는 비철금속 파이프를 고주파 용접기나 알곤 용접기로 용접할시 파이프 내면에 형성되는 용접 비이드를 냉각로울러로 형성 방지되게한 것에 관한 것이다.The present invention is to prevent the formation of the welding bead formed on the inner surface of the pipe by the cooling roller when welding the steel pipe, stainless pipe or non-ferrous metal pipe with a high frequency welder or argon welder.

종래 강철 파이프나, 스텐레스 파이프를 고주파 용접기나, 알곤 용접기로 용접할시 그 파이프 내면으로 용해된 비이드가 불규칙하게 형성되어 파이프를 사용할시 그 속도로 흐르는 유체(流體)속에 섞여 있는 진애(塵埃)가 걸려서 파이프를 부식시키는 원인이 될뿐만 아니라, 유체의 원활한 흐름을 저해하게 되었던 것이어서, 이를 금기하는 장소에서 사용되는 파이프는 그 내면에 형성된 용접 비이드를 절삭 방식으로 방지시켜 왔으나, 그 방식이 번거로워서 완전 제거는 어려운 결점이 있어 왔던 것이다.When welding a steel pipe or a stainless pipe with a high frequency welder or an argon welder, beads formed in the inner surface of the pipe are irregularly formed, and dust is mixed in the fluid flowing at the speed when the pipe is used. Not only cause the pipe to corrode, but also inhibit the smooth flow of the fluid, the pipe used in the contraindication place has been prevented by the welding method formed on the inner surface of the pipe, but the method is cumbersome Complete removal has had a difficult drawback.

그러므로 본 고안에서는 용접시 파이프 내면에 형성되는 용접비이드를 파이프 제조와 동시에 냉각 로울러로 형성방지되게 한 것으로서 이하 본 고안의 요지를 첨부된 도면에 의거 구조와 작용효과를 상세히 설명하면 다음과 같다.Therefore, in the present invention, the welding bead formed on the inner surface of the pipe during welding is prevented from being formed by the cooling roller at the same time as the manufacture of the pipe. Hereinafter, the structure and the effect of the present invention will be described in detail with reference to the accompanying drawings.

내부에 수공(1)(1')이 형성된 긴 냉각수관(2)(2')의 일단을 절곡시켜서 그단부(3)(3')에 냉각로울러(4)의 중심축(4')을 감삽회전되게 하되, 냉각로울러(4) 내부에 설한 원형의 수공(5)를 축(4')내에 설한 수공(5')과 연통되게 하여 긴 냉각 수관(2)(2') 내로 유입된 냉각수(6)가 냉각로울러(4) 내의 수공(5)으로 유입순환되게 하고 냉각로울러(4) 양측부에 가스 파이프(a)(b)를 부착되게 한 구조로, 미설명부호 7은 용접부, 7'는 파이프, 8은 종래 파이프(7') 내면에 형성된 용접비이드 9, 9'는 파이프 성형로울러 임.One end of an elongated cooling water pipe (2) (2 ') having a hand (1) (1') formed therein is bent and the central axis (4 ') of the cooling roller (4) is placed at its end (3) (3'). Cooling water flowing into the long cooling water pipe (2) (2 ') by allowing the circular water (5) installed inside the cooling roller (4) to communicate with the water (5') installed in the shaft (4 '). (6) is circulated into the water hole (5) in the cooling roller (4) and the gas pipe (a) (b) is attached to both sides of the cooling roller (4), the reference numeral 7 is a welded portion, 7 'Is a pipe, 8 is a weld bead 9 and 9' formed on the inner surface of a conventional pipe 7 'and a pipe forming roller.

이와같이 구성된 본 고안을 실시함에 있어서는 본 고안 제 3 도에 도시된 바와 같이 통상의 파이프(7')를 성형로울러(9)(9')로 성형함과 동시에 그 파이프(7') 내저면에 동 또는 탕크스텐과 특수합금등으로 성형된 냉각로울러(4)를 밀착시킨후 용접부(7) 상부에서 고주파 용접기나 혹은 알곤용접기로 용접을 실시하면서 파이프(7')를 "→"표 방향으로 서서히 진행시키면 파이프(7') 내저면에서 밀착회전되는 냉각로울러(4)는 긴 냉각수관(4) 내에 설한 수공(1)으로 유입되는 냉각수(6)가 수공(5)(5')으로 순환되면서 수공(1')을 통하는 동안 냉각로울러(4)는 계속 냉각 회전되는 것이어서, 항시 피용접 파이프(7')의 용해온도보다, 비교적 높은 온도로 유지되므로 용접부(7)에서 용융된 용철은 아래로 처지다가 그 내저면에서 밀착 회전되는 냉각로울러(4)의 상승 압력에 의해 내면 용접비이드(8)가 형성되지 않이하므로 양질의 파이프를 얻을 수 있게 되고, 피용접재가 스텐레스 파이프인 경우는 가스파이프(a)(b)로 알곤까스를 송입하여 실시할 수 있는 것인 바, 본 고안은 스텐레스나 또는 강철 및 비철금속으로 제조되는 여러 종류의 파이프 내에 성형되는 비이드를 제거할 수 있기 때문에 제조후 별도로 비이드 절삭공정이 불필요함과 동시 유채속에 섞여 있는 진애가 걸리지 아니하여 파이프의 부식 현상을 방지할 수 있어 그 수명을 장구화 할수 있는 효과가 있는 것이다.In carrying out the present invention configured as described above, as shown in FIG. 3, the general pipe 7 'is formed into a forming roller 9, 9' and at the same time the copper 7 'is formed on the inner bottom surface of the pipe 7'. Alternatively, the cooling roller (4) formed of the tank and the special alloy is brought into close contact with each other, and then the pipe (7 ') is gradually moved in the direction of the table "→" while welding with the high frequency welding machine or the argon welding machine on the upper part of the welding part 7. When the cooling roller 4 is rotated in close contact with the inner bottom of the pipe 7 ', the cooling water 6 flowing into the manual 1 installed in the long cooling water pipe 4 is circulated to the manual 5, 5'. The cooling roller 4 continues to be rotated while cooling through 1 ', so that molten iron in the welded portion 7 sags downward because it is always maintained at a relatively high temperature than the melting temperature of the welded pipe 7'. Is applied to the rising pressure of the cooling roller 4 which If the welding bead 8 is not formed, a high quality pipe can be obtained. If the welded material is a stainless steel pipe, algon cuts can be fed into the gas pipe (a) and (b). Since the present invention can remove the beads formed in various types of pipes made of stainless steel or steel and non-ferrous metals, no bead cutting process is required after manufacture and dust mixed in the oil paint is not caught. Corrosion can be prevented by the pipe, and its life is long.
