본 고안은 저융점 합금 용융 회수장치에 관한 것으로서, 특히 개스터어빈 엔진의 블레이드 등 부품의 가공시 부품을 고정하기 위해 사용된 저융점 합금을 다시 녹여 회수하는 장치에 관한 것이다.The present invention relates to a low melting point alloy melt recovery apparatus, and more particularly, to a device for remelting and recovering a low melting point alloy used to fix a part during processing of a part such as a blade of a gas turbine engine.
개스터어빈 엔진 예컨대, 항공기 젯트엔진의 콤푸레셔나 터어빈에 조립될 블레이드등의 부품을 제작하는 과정에서 이들 부품을 잡아주는 지구에 직접 물리지 않고 내경이 충분히 큰 요홈이 형성된 불록체에 블레이드의 하단을 집어넣고 요홈의 빈 공간에 녹은 상태의 저융점 합금을 부어 응고시킨뒤, 이 불록체를 치구에 물려 필요한 가공작업을 한다. 왜냐하면 이와같은 특수부품은 형태와 크기가 다양해서 적합한 치구를 일일이 마련하기도 힘들 뿐만 아니라 꼭 맞지않은 치구에 물릴 경우 변형이 생기거나 가공의 정밀도가 떨어지기 때문이다. 이와같이 부품고정 불록체에 사용되는 저융점 합금은 통산 70℃이면 용융되며, 부품 가공이 끝나면 이를 다시녹여 회수한 후 재사용 한다. 종래에는 저융점 합금을 회수하는 과정에서 합금이 국부적으로 증발되어 회수율이 낮으며 이때 발생하는 유독한 증기 때문에 작업안전을 크게 저해하는 요인이 되었다.In the process of manufacturing parts such as gas turbine engines, such as compressors of aircraft jet engines or blades to be assembled in turbines, the lower edge of the blade is placed in a block formed with a groove with a large enough internal diameter without being bitten directly by the earth holding them. The molten low-melting alloy is poured into the empty space of the groove to solidify, and the block is bitten into the jig for necessary processing. Because these special parts are diverse in shape and size, it is difficult to prepare a suitable jig at a time, and when they are bitten by a jig that does not fit, deformation or precision of machining are reduced. As such, the low-melting alloy used in the component fixing block is melted at 70 ° C in total, and when the parts are finished, they are melted and recovered and reused. Conventionally, in the process of recovering a low melting point alloy, the alloy is locally evaporated, and thus the recovery rate is low.
따라서 본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여 망체용기가 상부에 걸쳐지고 뚜껑이닫힌 물탱크를 간접 가열하도록 하고 상기 물탱크 하부에는 배출밸브를 설치하여서된 저융점 합금 용융 회수장치를 제공하는 것이다.Therefore, an object of the present invention is to solve the above problems, the indirect heating of the water tank and the lid closed over the water tank and the low melting point alloy melt recovery device by installing a discharge valve in the bottom of the water tank To provide.
이하 도면에 따라 본 고안의 한 바람직한 실시예를 상세히 설명한다. 바닥의 낮은 중앙에 배출밸브(4)가 설치된 배출관(3)이 마련된 탱크(1)의 상단에 걸림턱(5)을 형성하고 바닥 및 사방이 망체로 된 망체용기(8)의 상단 플렌지(9)를 상기 걸림턱(5)에 걸어 설치한다.According to the drawings will be described in detail one preferred embodiment of the present invention. The upper flange 9 of the mesh container 8 having a bottom and four-sided mesh container is formed on the upper end of the tank 1 provided with the discharge pipe 3 provided with the discharge valve 4 at the lower center of the bottom. ) Is installed on the hooking jaw (5).
한편, 탱크(1)의 주위에는 전기 히터선이 매입된 가열장치(11)를 탱크(1)의 외면으로 부터 일정거리를 유지하면서 탱크를 둘러싸도록 설치하고 상기 가열장치 외면밖에는 단열재(12)를 감싸도록 하여 작업자의 화상을 예방하여 보다 원활한 작업이 이루어지도록 한다. 상기 탱크의 상단에는 뚜껑체(2)를 닫는다. 배출관(3) 주위에도 가열장치(11)를 설치한다.On the other hand, around the tank (1) is installed so that the heating device (11) in which the electric heater wire is embedded to surround the tank while maintaining a certain distance from the outer surface of the tank (1), and the heat insulating material (12) outside the outer surface of the heating device is provided. It wraps up to prevent workers' burns and make the work more smooth. The lid 2 is closed at the top of the tank. A heater 11 is also provided around the discharge pipe 3.
이와같은 구성된 본 고안의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.
본 고안 저융점 합금 용융회수장치의 탱크(1)에 물을 채워 합금이 녹을 수 있는 온도를 유지하면서 가공이끝난 부품이 저융점 합금에 의해 고정되어 있는 블록체를 망체용기(8)에 담아 탱크에 담근후 일정시간이 경과하면 저융점 합금이 블록체로부터 녹아내려 탱크바닥으로 하강하고 가공부품이나 블록체등은 망체용기(8)에남게된다. 합금이 완전히 녹아내려 탱크바닥에 고이면 밸브(4)를 열어 배출관(3)을 통해 밖으로 회수한다. 이때 배출관(3) 주위에도 적당한 열량을 공급하도록 가열장치(11)가 마련되어 있기 때문에 용융된 합금이 회수도중 굳는다는 일은 없다.The tank 1 of the present invention low melting point alloy melt recovery device is filled with water to maintain a temperature at which the alloy can melt, and the block body in which the finished parts are fixed by the low melting point alloy is contained in the net container 8. After a certain period of time, the low melting point alloy melts from the block body and descends to the bottom of the tank, and the machined parts and the block body remain in the mesh container 8. If the alloy melts completely and collects on the bottom of the tank, open the valve (4) and withdraw it out through the discharge pipe (3). At this time, since the heating device 11 is provided to supply an appropriate amount of heat around the discharge pipe 3, the molten alloy does not harden during recovery.
본 고안에서는 탱크내의 물의 온도를 저융정 합금이 녹을 정도로 낮게 유지하기 때문에 지나친 고온으로 인하여 합금이 증발하는 가능성을 극소화 시킨다. 또한 혹시나 있을 미량의 증발분에 대비해 뚜껑(2)을 덮어 놓으므로 안전상 거의 완벽을 기할 수 있다.In this design, the temperature of the water in the tank is kept low enough to melt the low melting alloy, thereby minimizing the possibility of the alloy evaporating due to excessive high temperature. In addition, the lid (2) is covered in case of a small amount of evaporation may be almost perfect for safety.
이상과 같이 본 고안에 의하면 저용융합금을 거의 손실없이 용융회수할 수 있을 뿐 아니라 매우 안전하며 회수작업 또한 간편하다.As described above, according to the present invention, the low melt alloy can be melt-recovered with almost no loss, as well as very safe and easy to recover.
