Description

용접로의 구조 {Weld shop structure}Weld shop structure}

본 발명은 용접로의 구조에 관한 것으로, 더 상세하게는 알루미늄 저온 용접시 용접로 내로 운반 및 투입되는 용접대상물을 수직으로 상승 및 하강되며 용접로의 저면으로 출입되도록 하고 용접로 내의 열에 의해 무산소 상태로된 상태에서 용접하게 되므로 후랏스와 용접재의 산화를 방지하고, 용접로 내의 열 손실을 최소로 줄여 항상 일정한 온도를 유지한 상태에서 용접작업이 이루어지게 됨에 따라, 작업시간의 단축과 용접불량을 최소로 줄일 수 있도록 한 용접로의 구조에 관한 것이다.The present invention relates to a structure of a welding furnace, and more particularly, to a welding object conveyed and introduced into the welding furnace during aluminum low-temperature welding is vertically raised and lowered to enter and exit the bottom of the welding furnace and anoxic state by heat in the welding furnace. As welding is done in the furnace, it prevents the oxidation of the flats and the welding material and minimizes the heat loss in the welding furnace, so that the welding work is performed at a constant temperature at all times, thereby reducing the work time and welding defects. It is about the structure of a welding furnace so that it can be reduced.

일반적으로 알루미늄 저온 용접시에 사용되는 종래의 용접로는 개폐식 또는 컨베이어식이 사용된다.In general, the conventional welding furnace used in the low temperature aluminum welding is open or closed.

종래 개폐식 용접로는 용접시 용접대상물이 출입되는 통로가 측면에 형성되고 이 통로를 개폐되게 하여 용접을 하게 된다.In the conventional open and close welding furnace, a passage through which a welding object enters and exits is formed on a side of the welding furnace, and the welding is performed by opening and closing the passage.

그러나 전술한 바와 같은 구조는 용접대상물의 출입시 통로가 개폐되면서 용접로 내의 열이 통로를 통해 급격히 빠져나가 열손실이 과다하게 많이 발생하여 다음 차례의 용접작업시에는 일단 온도가 떨어진 용접로 내를 재차 가열하여 일정온도 까지 유지하여야 하므로 용접시간이 과다하게 많이 소요되고, 이에 따라 작업에 따른 비용이 상승될 뿐 아니라, 통로의 개폐시 투입된 산소가 불완전연소된 상태에서 용접이 이루어지므로 후랏스와 용접재가 산화되어 용접불량이 발생하게 되는 문제점이 발생하고 있는 실정이다.However, the structure as described above, when the passage of the welding object is opened and closed, the heat in the welding furnace suddenly escapes through the passage, causing excessive heat loss. The heating time must be maintained again to a certain temperature, so the welding time is excessively increased. Accordingly, the cost of the work is increased. In addition, the welding is performed in the state of incomplete combustion of oxygen introduced during the opening and closing of the passage. It is a situation that a problem occurs that the welding failure caused by oxidation.

그리고 컨베이어식의 경우는 컨베이어 자체의 부피가 커서 설치공간이 과다하게 소요될 뿐 아니라, 용접로 내에 질소를 투입하여 산화를 방지하고, 산소를 제거하게 되므로 질소 투입에 따른 별도의 설비가 필요하게 됨에 따라 설치가 복잡해지고 개폐식과 마찬가지로 용접시 불완전 연소상태로 용접 작업이 실시되므로 산화 및 용접불량이 자주 발생하게 되는 등의 문제점이 있다.In the case of the conveyor type, because the volume of the conveyor itself is large, the installation space is excessively consumed, and since nitrogen is introduced into the welding furnace to prevent oxidation and oxygen is removed, a separate facility according to nitrogen input is required. Since the installation is complicated and the welding operation is performed in an incomplete combustion state during welding as in the opening and closing type, there are problems such as frequent occurrence of oxidation and welding defects.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 알루미늄 저온 용접시 용접로 내로 운반 및 투입되는 용접대상물을 수직으로 상승 및 하강되며 용접로의 저면으로 출입되도록 하고 용접로 내의 열에 의해 무산소 상태로된 상태에서 용접하게 되므로 후랏스와 용접재의 산화를 방지하고, 용접로 내의 열 손실을 최소로 줄여 항상 일정한 온도를 유지한 상태에서 용접작업이 이루어지게 됨에 따라, 작업시간의 단축과 용접불량을 최소로 줄일 수 있도록 한 용접로의 구조를 제공하는데 있다.Therefore, the object of the present invention is to devise to solve the conventional problems as described above, the welding object to be transported and put into the welding furnace in the case of aluminum low-temperature welding is raised and lowered vertically to enter and exit the bottom of the welding furnace and the welding furnace Since the welding is performed in the anoxic state by the heat inside, it prevents oxidation of the flats and the welding material and reduces the heat loss in the welding furnace to the minimum, so that the welding work is always performed at a constant temperature, thereby reducing the work time. It is to provide a structure of a welding furnace to minimize the amount of welding failure.

상기와 같은 본 발명은 알루미늄 저온 용접시 용접대상물이 담겨진 용접로 내로 운반 및 투입되는 플레이트가 용접로의 저면에서 수직으로 상승 및 하강되며 용접로의 저면으로 출입되도록 하여 용접로 내의 온도가 방출되는 것을 최소로 줄임과 동시에 용접시 용접로 내로 투입된 산소를 용접로 내의 자체 열로 완전제거한 상태에서 용접작용을 실시할 수 있도록 한 용접로의 구조를 제공함을 기술적 과제로 삼는다.The present invention as described above is that the plate conveyed and introduced into the welding furnace containing the welding object during the low temperature welding of aluminum is raised and lowered vertically at the bottom of the welding furnace to be discharged into the bottom of the welding furnace so that the temperature in the welding furnace is released. It is a technical task to provide a structure of a welding furnace which can reduce welding to the minimum and perform welding operation in which the oxygen introduced into the welding furnace is completely removed by its own heat in the welding furnace.

전술한 바와 같은 본 발명의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention as described above are as follows.

최초 용접대상물(10)을 플레이트(1)에 올려 놓은 후, 제어부(3)의 온오프스위치(3a)를 온상태로 작동시킨다.After the initial welding object 10 is placed on the plate 1, the on-off switch 3a of the controller 3 is operated in an on state.

이때 시간, 횟수, 속도는 제어부(3)의 컨트롤러(3b)를 이용하여 조절하면 된다.In this case, the time, frequency, and speed may be adjusted by using the controller 3b of the controller 3.

상기와 같이 온상태로된 이송실린더(2)가 작동하면 이송실린더(2)에 설치된 플레이트(1)가 상승하여 용접로(4) 저면의 통로(5)를 통해 도2와 같이 용접로(4) 내로 투입되게 된다.When the transfer cylinder 2 is turned on as described above, the plate 1 installed in the transfer cylinder 2 is raised to raise the welding furnace 4 as shown in FIG. 2 through the passage 5 at the bottom of the welding furnace 4. ) Will be put into.

상기와 같은 상태가 되면 플레이트(1)가 용접로(4)의 통로(5)를 차단하여 용접로(4) 내부로는 산소공급이 차단되고, 이미 공급되어진 산소는 용접로(4) 내의 열에 의해 제거되어 용접로(4) 내부는 단시간내에 무산소 상태가 됨에 따라 용접작업이 무산소상태에서 이루어지게 되는 것이다.In this state, the plate 1 blocks the passage 5 of the welding furnace 4 so that oxygen supply is cut off into the welding furnace 4, and the oxygen already supplied is transferred to the heat in the welding furnace 4. By removing the inside of the welding furnace (4) is an oxygen-free state in a short time, the welding operation is to be made in an oxygen-free state.

한편 본 발명의 다른 실시예에 의하면, 상기 플레이트(1) 하부로 소정간격 이격되어 형성된 보조플레이트(1a)가 플레이트(1)가 용접로(4) 내로 상승하면 용접로(4)의 통로() 저면을 도4와 같이 차단하여 용접로 내로 공기가 침투하는 것을 2중으로 차단하게 된다.Meanwhile, according to another exemplary embodiment of the present invention, when the plate 1 rises into the welding furnace 4, the auxiliary plate 1a formed at a predetermined interval below the plate 1 passes through the welding furnace 4. The bottom surface is blocked as shown in FIG. 4 to double the penetration of air into the welding furnace.

이와 같이 용접로(4) 내로 투입된 용접대상물(10)이 일정시간이 경과하여 용접이 완료된 후에는 컨트롤러(3b)에 입력된 신호에 의해 다시 이송실린더(2)가 작동하여 플레이트(1)가 하강하게 되어 도3의 위치로 원위치 되게 된다.As described above, after the welding object 10 introduced into the welding furnace 4 is completed after a predetermined time, the transfer cylinder 2 is operated again by a signal input to the controller 3b to lower the plate 1. It will be returned to the position of FIG.

이때 용접대상물(10)에는 끈끈하게 만든 후랏스를 용접부위에만 실크스크린으로 바른 다음 이 상태에서 용접재를 부착하게 되므로 용접완료시 용접이 정확하고 균일하게 이루어지게 되는 것이다.At this time, the welding object 10 is made of a sticky furas applied to the silk screen only on the welding site, and then the welding material is attached in this state, so that the welding is completed accurately and uniformly when the welding is completed.

상기와 같은 본 발명은 알루미늄 저온 용접시 용접대상물의 용접로의 저면으로 출입되며, 투입된 상태에는 통로가 차단되므로 산소의 공급이 차단되며 이미 공급되어지 산소는 용접로 내의 열에 의해 급격히 제거되어 용접로 내부는 무산소 상태에서 용접작업이 진행되므로 후랏스와 용접재의 산화를 방지함에 따라, 용접불량을 최소로 줄이고, 용접효율을 극대화 하는 한편, 용접로 내의 열 손실을 최소로 줄여 항상 일정한 온도를 유지한 상태에서 용접작업이 이루어지게 됨에 따라, 작업시간의 단축과 더불어 작업에 소요되는 비용을 절감하여 경제적인 이득을 기대할 수 있는 아주 유용한 발명이다.In the present invention as described above, when the low temperature welding of aluminum, the entrance and exit of the welding object of the welding object, the passage is blocked in the input state, the supply of oxygen is cut off and the oxygen already supplied is rapidly removed by the heat in the welding furnace As the welding work is carried out in an oxygen-free state, it prevents oxidation of the flats and welding materials, thereby minimizing welding defects, maximizing welding efficiency, and minimizing heat loss in the welding furnace to maintain a constant temperature at all times. As the welding work is performed in, it is a very useful invention that can expect economic benefits by reducing the time required for work as well as shortening the working time.
