이와 같은 본 고안은 기대에 설치한 여러개의 안내롤러(17)에 의하여 금속판을 점차 둥글게 말아 이송시키면서 전기히터(13)에 의한 전기저항고주파용접에 의하여 제조되는 파이프(12)내에다 철관(3)과 연결봉(4)으로 연결된 대차(2)와 냉각수공급구(1)를 도1 및 도2와 같이 고정상태로 위치시켜 펌프(14)에 의하여 냉각수를 공급하면서 대차(2)에 고정한 바이트(9)에 의하여 파이프(12)내면의 용접비드(BEAD)를 절삭하여 제거시키게되는 것은 종래와 동일한 바,The present invention as described above is iron pipe (3) in the pipe (12) produced by the electric resistance high frequency welding by the electric heater 13 while conveying the metal plate gradually rounded by a plurality of guide rollers (17) installed on the base And the bogie 2 and the coolant supply port 1 connected by the connecting rod 4 and the fixed water in the bogie 2 while supplying the coolant by the pump 14 as shown in FIGS. By cutting the weld bead (BEAD) of the inner surface of the pipe 12 by the same as the conventional bar,
상기에 있어서 본 고안은 철관(3)에는 냉각수역분사구(7)를 고정하여 냉각수공급구(1)로 유입되는 냉각수를 역으로 분사시킬 수 있는 구조로 구성하였으므로 냉각수공급구(1)로 유입되어 카본(6)을 냉각시킨 냉각수는 밀폐판(11)에 의하여 도3과 같이 앞쪽으로 분사됨이 없이 철관(3)의 구멍(301)으로 유입되어 도1과 같이 냉각수역분사구(7)로 분사케된다.In the present invention is the iron pipe (3) is fixed to the cooling water injection port (7) has been configured to the structure that can be injected back to the cooling water flowing into the cooling water supply port (1) is introduced into the cooling water supply port (1) The cooling water having cooled the carbon 6 is introduced into the hole 301 of the steel pipe 3 without being sprayed forward by the sealing plate 11 as shown in FIG. 3 and sprayed into the cooling water injection hole 7 as shown in FIG. Sake
이에 따라 용접에 의하여 파이프(12)의 내면에 떨어지는 용접똥(15)은 파이프(12)의 진행방향 반대쪽으로 씻겨 이동되어 외부로 배출되기 때문에 대차(2)의 하부롤(9)에 용접똥(15)이 눌여지는 일이 없게되어 용접똥(15)의 압착에 의하여 파이프(12)의 내면에 핀홀이 발생되는 것을 방지할 수 있다.Accordingly, the welding dung 15 falling on the inner surface of the pipe 12 by welding is washed and moved to the opposite side in the advancing direction of the pipe 12 to be discharged to the outside, so that the welding dung ( It is possible to prevent the pinholes from occurring on the inner surface of the pipe 12 due to the crimping of the welding dung 15 because the 15 is not pressed.
이와 같은 본 고안은 철관(3)에는 냉각수역분사구(7)를 고정하여 냉각수공급구(1)로 유입되는 냉각수를 역으로 분사시킬 수 있는 구조로 구성하였으므로 역으로 분사되는 냉각수에 의하여 용접시에 파이프(12)에 떨어지는 용접똥(15)은 외부로 씻겨 배출됨으로 대차(2)의 하부롤(9)에 눌여짐이 방지된다.The present invention has a structure in which the cooling water flowing into the cooling water supply port (1) is fixed to the steel pipe (3) by injecting the cooling water flowing into the cooling water supply port (1) in the reverse direction when welding by the cooling water injected back The welding dung 15 falling on the pipe 12 is washed out and discharged to the bottom roll 9 of the trolley 2 to prevent it from being pressed.
이에 따라 용접똥(15)이 하부롤(9)에 눌여지게 됨으로 인한 핀홀이 발생되는 것을 방지할 수 있는 효과가 있다.Accordingly, the welding dung 15 may be prevented from generating a pinhole due to being pressed by the lower roll 9.
