진공 침탄로의 중간문 개폐장치{Vacuum carburizing furnace of middle door opening and shutting device}Vacuum carburizing furnace of middle door opening and shutting device}

본 고안은 진공 침탄로의 개폐장치에 관한 것으로, 보다 상세하게는 도어의 하부에 형성된 롤러를 구비하여 도어 개폐시 전진 이격과 후진 밀착되게 구성함에 따라, 도어의 잦은 개폐에 따른 마모를 방지함과 함께 밀폐력을 더욱 향상시키고, 도어상에 단열판을 구비하여 높은 고열을 견딜 수 있는 진공 침탄로의 중간문 개폐장치에 관한 것이다.The present invention relates to an opening and closing device of a vacuum carburizing furnace, and more specifically, having a roller formed on the lower part of the door to be configured to be closely spaced forward and backward when opening and closing the door, to prevent wear due to frequent opening and closing of the door and The present invention relates to an intermediate door opening and closing device of a vacuum carburizing furnace, which further improves a sealing force and is capable of withstanding high heat by providing an insulating plate on the door.

통상적으로, 진공침탄기술은 1970년대 후반에 실용화되어 단기간에 많은 발전을 거듭하며 침탄시간의 획기적인 단축과 침탄층의 균일성 확보로 경제성과 품질향상면에서 성공적인 평가를 받아왔다. 이러한 진공침탄은 진공 중에서 행해지는 고온침탄공정으로 침탄온도는 보통 980℃~1050℃정도의 고온에서 처리를 하게 된다.In general, vacuum carburizing technology has been put to practical use in the late 1970s, and has been developed in a short period of time, and has been successfully evaluated in terms of economic efficiency and quality improvement due to the drastic reduction of carburizing time and uniformity of the carburizing layer. This vacuum carburizing is a high temperature carburizing process performed in a vacuum and the carburizing temperature is usually treated at a high temperature of about 980 ° C to 1050 ° C.

이러한 진공침탄기술은 진공상태에서 처리품을 설정된 침탄온도까지 가열한 후 진공상태에서 메탄이나 프로판 등의 탄화수소 가스를 투입시켜 분해과정 중에 생긴 탄소로 침탄을 하고, 다시 진공상태에서 확산처리를 한 다음 오일 담금질이나 가스 담금질의 방법으로 냉각하여, 침탄과 확산처리를 반복함으로써 원하는 침탄층을 만든 후, 침탄공정을 5분 이내로 처리하면서 탄소를 침투시켜 소정의 표면탄소량을 얻게 되는 게 일반적이다.In this vacuum carburizing technology, a processed product is heated to a set carburizing temperature in a vacuum state, and then a hydrocarbon gas such as methane or propane is introduced in a vacuum state to carburize with carbon generated during the decomposition process, followed by diffusion treatment in a vacuum state. Cooling by oil quenching or gas quenching to repeat the carburizing and diffusion treatment to form the desired carburizing layer, and then infiltrating the carbon while the carburizing process is performed within 5 minutes to obtain a predetermined surface carbon amount.

하지만, 이러한 침탄을 얻기 위해서는 가열실이 공기밀폐와 고열을 차단하는 기능을 동시에 수행해야하나 종래의 침탄로의 개폐장치의 개폐 도어는 잦은 개폐에 따른 마모가 빈번하여 확실한 공기밀폐의 어려움이 있고, 높은 고열을 견디지 못하는 문제점이 발생하였다.However, in order to obtain such carburization, the heating chamber must simultaneously perform a function of blocking air sealing and high heat, but the opening and closing door of a switchgear of a conventional carburizing furnace has frequent wear and tearing due to frequent opening and closing. There was a problem that can not withstand high heat.

이에 따라 본 고안은 상기와 같은 종래의 문제점을 근본적으로 해결하기 위한 것으로서, 도어의 하부에 형성된 롤러를 구비하여 도어 개폐시 전진 이격과 후진 밀착되게 구성함에 따라, 도어의 잦은 개폐에 따른 마모를 방지함과 함께 밀폐력을 더욱 향상시키고, 도어상에 단열판을 구비하여 높은 고열을 견딜 수 있는 진공 침탄로의 중간문 개폐장치를 제공하려는데 그 목적이 있는 것이다.Accordingly, the present invention is to fundamentally solve the conventional problems as described above, and provided with a roller formed on the lower portion of the door to be configured to be closely spaced forward and backward when opening and closing the door, to prevent wear due to frequent opening and closing of the door. In addition, to further improve the sealing force, and to provide an intermediate door opening and closing device of the vacuum carburizing furnace that can withstand high heat by providing an insulating plate on the door.

At this time, the connecting portion 32 is rotated interposed on the shaft formed in the guide plate 40, like the door 30, to prevent the separation by engaging the snap ring (33).

또, 본 고안에 따른 실린더(50)는 가이드플레이트(40)의 상부에 피스톤로드(51)로 연결되고, 컴프레서의 유압력에 의한 작동력을 제공한다. 이때, 실린 더(50)의 작동에 의해 도어(30)와 가이드플레이트(40)가 상하왕복 운동을 수행한다. 이때, 실린더(50)는 반드시 복동식을 사용할 필요는 없고 도어(30)가 중량물이므로 단동식이어도 무방하다.In addition, the cylinder 50 according to the present invention is connected to the piston rod 51 on the upper portion of the guide plate 40, and provides an operating force by the hydraulic force of the compressor. At this time, the door 30 and the guide plate 40 perform the up and down movement by the operation of the cylinder 50. At this time, the cylinder 50 does not necessarily need to use a double-acting type, and since the door 30 is a heavy object, it may be a single-acting type.

또, 본 고안에 따른 롤러(60)는 도어(30)의 하부에 연결되어 가열실(20)의 전방 하측에 설치된 스토퍼(34)상으로 수평이동 가능하게 전진이격과 후진 밀착된다. 롤러(60)는 상기 도어(30)의 하부에 연결되어 도어(30)를 전체적으로 이동하는 역할을 수행한다. 이때, 롤러(60)는 상기 가열실(20)의 전방 하측에 설치되어 롤러(60)와 직하방으로 일치되게 형성되는 스토퍼(34)에 안착하여 상기 도어(30)가 이동을 하게 된다.In addition, the roller 60 according to the present invention is connected to the lower portion of the door 30 is in close contact with the forward space and the backward movement so as to move horizontally on the stopper 34 installed in the front lower side of the heating chamber 20. The roller 60 is connected to the lower portion of the door 30 to move the door 30 as a whole. At this time, the roller 60 is installed in the front lower side of the heating chamber 20 is seated on the stopper 34 formed to be in direct and downward correspondence with the roller 60 to move the door 30.

도 4는 본 고안에 따른 침탄로의 중간문 개폐장치의 평면도이다.4 is a plan view of the intermediate door opening and closing device of the carburizing furnace according to the present invention.

도 4에 도시된 바와 같이 도어(30)는 폐쇄시 가열실(20)의 내부에 삽입하여 밀착되는 단열판(35)이 형성된다. 단열판(35)은 상기 도어(30)의 내면에 결합하여 폐쇄시 가열실(20)의 내부에 삽입하게 된다. 이때, 단열판(35)은 가열실(20)에서 발생되는 고열을 차단시켜 도어(30)에 직접적인 열기를 차단한다.DAs shown in FIG. 4, the door 30 has a heat insulating plate 35 which is inserted into and close to the inside of the heating chamber 20 when the door 30 is closed. The insulation plate 35 is coupled to the inner surface of the door 30 to be inserted into the heating chamber 20 when closed. At this time, the heat insulating plate 35 blocks the high heat generated in the heating chamber 20 to block direct heat to the door 30.

도 1 내지 도 4를 통하여 진공 침탄로의 중간문 개폐장치의 작동에 있어서, 우선 도어(30)가 닫힐 때에는 상기 가이드플레이트(40)의 상부에 피스톤로드(51)로 연결된 실린더(50)가 컴프레서의 유압력에 의해 하단으로 작동함과 동시에 도어(30)에 연결된 브라켓(31)에 의해 도어(30)도 함께 하방향으로 이동하게 된다. In the operation of the intermediate door opening and closing device of the vacuum carburizing furnace through FIGS. 1 to 4, first, when the door 30 is closed, the cylinder 50 connected to the upper part of the guide plate 40 by the piston rod 51 is compressed. The door 30 is also moved downward by the bracket 31 connected to the door 30 at the same time by operating the hydraulic pressure of the lower.

이때, 도어(30)의 하부에 연결되어 있는 롤러(60)가 하방향으로 이동하여 스토퍼(34)상에 안착되고, 스토퍼(30)를 타고 가열실(20)방향으로 수평이동하게 된 다. 그와 동시에 가이드플레이트(40)와 도어(30)가 연결된 연결부(32)는 가이드플레이트(40)와 결합된 일측 부분을 축으로 회동하여 상기 도어(30)를 가열실(20)방향으로 밀접하게 이동하여 도어(30)가 폐쇄된다. At this time, the roller 60 connected to the lower portion of the door 30 moves downward and is seated on the stopper 34, and is horizontally moved in the direction of the heating chamber 20 by the stopper 30. At the same time, the connecting portion 32 to which the guide plate 40 and the door 30 are connected rotates on one side coupled with the guide plate 40 about the shaft to closely close the door 30 toward the heating chamber 20. The door 30 is closed by moving.

그리고, 도어(30)가 열릴 때에는 상기 실린더(50)에 의해 피스톤로드(51)가 상단으로 작동하여 도어(30)에 연결된 브라켓(31)에 의해 도어(30)도 상방향으로 이동하게 된다. 이때, 도어(30)의 하부에 연결되어 있는 롤러(60)가 상방향으로 이동하여 스토퍼(34)상에 안착되어 스토퍼(30)를 타고 가열실(20)방향으로 수평이동하였던 롤러(60)가 상기 스토퍼(34)와 분리되고, 도어(30)의 자중에 의해 가이드플레이트(40)에 연결된 연결부(32)의 일측을 축으로 하방향으로 회동하여 도어(30)가 개폐된다. When the door 30 is opened, the piston rod 51 is operated to the upper end by the cylinder 50 so that the door 30 is also moved upward by the bracket 31 connected to the door 30. At this time, the roller 60 which is connected to the lower portion of the door 30 moves upward and is seated on the stopper 34 to move horizontally toward the heating chamber 20 by riding the stopper 30. Is separated from the stopper 34, and the door 30 is opened and closed by rotating one side of the connecting portion 32 connected to the guide plate 40 downward by the own weight of the door 30.

이로써, 도어(30)의 개폐시 전진 이격과 후진 밀착되므로, 도어의 잦은 개폐에 따른 마모를 방지하고, 도어(30)상에 단열판(35)을 구비하여 높을 고열을 견딜 수 있게 된다.
