샌드블라스트머시인용 노즐Sandblast Machine Nozzles

첨부된 도면은 본 고안의 일부 단면을 나타낸 정면도이다.The accompanying drawings are front views showing some cross sections of the present invention.

본 고안은 주물이나 강철판 등의 표면에 붙어 있는 모래나 스케일 등을 제거하기 위하여 사용되는 샌드블라스트머시인에 있어서 이에 취부하여 사용하는 노즐의 개량에 관한 것이다.The present invention relates to an improvement of a nozzle for use in sandblast machines used to remove sand, scales, etc. adhered to surfaces of castings, steel sheets, and the like.

종래 샌드블라스트머시인용 노즐을 보면 단순한 원통형으로 된 듀랄루민제 외관에 세라믹재의 원통형 내관을 내삽하여 사용하였는데, 여기에 사용되는 세라믹은 상당히 강한 재료이기는 하나 샌드블라스트작업시 모래가 통과할 때 발생되는 마찰력이 워낙 크기 때문에 5시간 이상은 견뎌내지 못하는 결점이 있었다. 그렇다면 내관을 세라믹 대신에 좀더 강한 재질인 초경합금 등을 이용할 필요가 있는데 이초경합금은 원통체인 듀랄루민재 외관과 접합이 잘 되지 않아 사용중 초경합금재 내관이 이탈할 우려가 있어 이것 또한 지금까지 사용이 불가능하였다.In the conventional sandblasting machine nozzle, the cylindrical inner tube of ceramic material was used by inserting a simple cylindrical shape of duralumin. The ceramic used here is a very strong material, but the frictional force generated when sand passes through sandblasting Because of its size, there was a flaw that could not endure more than five hours. Then, it is necessary to use cemented carbide, which is a stronger material, instead of ceramics. This cemented carbide is not easily bonded to the outer body of the durrallumin material.

본 고안은 종래 이러한 문제점을 해결하기 위하여 안출한 것으로 듀랄루민재 외관과 초경합금재 내관을 종래와 같이 단순한 원통형으로 구성하지 않고 중간에 공간부를 가진 잘록부를 형성한 다음 공간부에 금속용융액을 충전시킴으로써 내 외관을 견고하게 결합할 수 있게 한 것이다.The present invention has been devised to solve such a problem in the prior art, and the inner appearance of the duralumin material and the cemented carbide inner tube is not formed in a simple cylindrical shape as in the prior art, but a convex part having a space in the middle is formed and then the metal melt is filled in the space. It is to be able to combine the firmly.

이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings as follows.

즉 후방에 나사부(2)를 형성한 통상의 노즐외관(1)에 내부로 통하는 통공(3)(3')을 전후로 두 개 공하고 선단에 걸림턱(4)를 형성하며, 내부에 후향 확개되는 경사면(5)을 형성하고, 내관(6)은 거의 중앙에 외경이 t2인 잘록부(7)을 두고 그 선단부(8)의 외경은 t2보다 약간 큰 t1이 되게 하고, 후단부(9)의 외경은 t1보다 큰 t3가 되게 형성하여 이를 외관(1)의 내부에 완전히 삽입한 다음 통공(3)(3')을 통하여 외관(1)의 내면과 내관(6)의 외면 사이에 형성되는 공간부(10)에 금속용융액(11)을 충전시켜 내, 외관(6)(1)을 결합하는 것이다.That is, two holes (3, 3 ') which pass through the inside of the normal nozzle shell (1) having the threaded portion (2) formed in the rear two holes back and forth, and the locking jaw (4) is formed at the front end, and the rearward extension The inclined surface 5 is formed, and the inner tube 6 has a narrow portion 7 having an outer diameter t 2 at its center and the outer diameter of the tip portion 8 is slightly larger than t 2 , and the rear end portion ( The outer diameter of 9) is formed to be t 3 larger than t 1 , and it is completely inserted into the inside of the exterior 1, and then the inner surface of the exterior 1 and the outer surface of the inner tube 6 through the through holes 3 and 3 ′. The molten metal 11 is filled in the space 10 formed therebetween, and the exterior 6 and 1 are joined together.

이와 같이 구성된 본 고안은 내관(6)의 잘록부(7)가 형성된 외면과 외관(1)의 경사면(5)이 형성된 내면 사이의 공간부(10)에 금속용융액(11)이 충전되어 굳어지면서 내, 외관(6)(1)을 완전 결합시키며 내관(6)의 선단부(9)와 후단부(8)의 외경이 잘록부(7)의 외경보다 크기 때문에 내관(6)이 공간부(10)에 충전된 금속용융액(11)에 의해 외관(1)으로부터 이탈될 염려가 전혀 없으며 내관(6)의 재질이 초경합금이기 때문에 수명이 220시간 정도 되어 종래 세라믹으로 된 노즐에 비해 월등한 성능을 지닌 것이다.The present invention configured as described above fills and hardens the metal melt 11 in the space portion 10 between the outer surface on which the concave portion 7 of the inner tube 6 is formed and the inner surface on which the inclined surface 5 of the exterior 1 is formed. The inner tube 6 is spaced 10 because the inner and outer surfaces 6 and 1 are completely coupled and the outer diameters of the front end 9 and the rear end 8 of the inner tube 6 are larger than the outer diameter of the narrowed portion 7. ), There is no fear of being separated from the exterior (1) by the metal melt (11) filled in the inner shell, and since the material of the inner pipe (6) is cemented carbide, the service life is about 220 hours, which is superior to that of a conventional ceramic nozzle. will be.
