본 발명은 터빈(turbine)에 관한 것으로, 터빈에 사용되는 베인(vane)을 견고하게 고정시키는 핀실(pin seal)이나 베인핀실(vane pin seal)을 효과적으로 가공할 수 있는 가공수단과, 이러한 가공수단을 이용하여 베인핀실(vane pin seal)을 효과적으로 가공하는, 핀실가공용 롤커터(roll cutter) 및 이를 이용한 핀실 가공방법, 그리고 이를 이용 가공한 베인핀실(vane pin seal)을 제시한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turbine, comprising: processing means capable of effectively processing a pin seal or a vane pin seal for firmly fixing vanes used in a turbine, and such processing means. By using a vane pin seal (vane pin seal) to effectively process, a pin cutter roll cutter (roll cutter) and a pin seal processing method using the same, and a vane pin seal (vane pin seal) processed using the same.

베인(vane)은 증기터빈이나 개스터빈 등 터빈에서 케이싱(casing) 안쪽에 고정되는 고정날개이다. 이러한 베인(vane)은 항공기의 날개와 비슷한 에어포일(airfoil) 형상을 띠며, 제트엔진 터빈의 회전체에 조립되어 엔진의 성능에 가장 중요한 역할을 하는 핵심 부품으로, 인입되는 고온 고압가스나 증기 에너지를 블레이드(Blade)로 연결하여 회전 에너지로 전환시켜줌으로써 압축기나 발전기를 구동시키거나 발전시키는 역할을 한다.A vane is a fixed vane fixed inside a casing in a turbine such as a steam turbine or a gas turbine. These vanes have an airfoil shape similar to the wing of an aircraft, and are assembled in the rotor of a jet engine turbine and play an important role in the engine's performance. It is connected to the blade (Blade) to convert the rotational energy to drive or generate a compressor or generator.

도 1은 일반적인 발전용 터빈의 케이싱(casing)에 대한 구조의 일부분을 나타낸 도면이다. 1 is a view showing a part of the structure for the casing (casing) of a general turbine for power generation.

도시한 바와 같이, 터빈 케이싱(10, turbine casing)은 케이싱프레임(110)의 내부에 수많은 베인(vane, 120)을 부착하고 있다. 전술한 바와 같이 이러한 베인(vane, 120)은 분출되어 인입되는 고온 고압가스나 증기 에너지를 블레이드(Blade)로 연결하여 회전 에너지로 전환시켜줌으로써 압축기나 발전기를 구동시 키게 된다. As shown, the turbine casing 10 attaches a number of vanes 120 to the inside of the casing frame 110. As described above, the vanes 120 drive the compressor or the generator by converting the high-temperature, high-pressure gas or steam energy, which is ejected and introduced into the blade, into the rotational energy.

도 2는 터빈 케이싱 일부를 나타낸 도 1의 'A'부분에 대한 분해사시도이다.FIG. 2 is an exploded perspective view of portion 'A' of FIG. 1 showing a portion of the turbine casing. FIG.

도시한 바와 같이 터빈 케이싱(10)은 케이싱프레임(110)에 다른 구성부품들과 함께 베인(120, vane)을 결합시켜 형성하게 된다. As shown in the drawing, the turbine casing 10 is formed by coupling vanes 120 and vanes together with other components to the casing frame 110.

터빈 케이싱(10)에 있어 이러한 베인(120, vane)은 그 내부에 빼곡하게 회전결합시켜 형성되며, 각 베인(120) 간은 베인핀실(130, vane pin seal)을 삽입시킨 상태로 결합시키게 된다. 이렇게 함으로써, 터빈 내부로 유입된 가스나 증기가 외부로 새어나가는 것을 방지함과 동시에 각 베인(120)들의 결합을 더욱 강하게 유지하게 된다.In the turbine casing 10, these vanes (120, vane) is formed to be rotatably coupled in the interior, each vane 120 is coupled to the state in which the vane pin seal (130, vane pin seal) is inserted. . In this way, the gas or vapor introduced into the turbine is prevented from leaking to the outside, and at the same time, the combination of the vanes 120 is more strongly maintained.

하지만 이러한 베인핀실(130, vane pin seal)은 삽입고정시킬 베인(120)의 삽입홀에 잘 맞도록 결합되어야 하는 것이 중요하다. 이 삽입홀에 맞지 않아 틈새가 생기면, 그 틈새로 스팀이나 가스가 새어나가기 때문에 정상적이고 효율적인 작동이 이루어지지 못하게 된다. 때문에 하나의 베인(120)과 이에 이웃하는 베인(120)의 삽입홀 각각을 정확히 맞추어 질 것이 요구된다. 그러나 각 베인(120)의 삽입홀은 라운드져 있어 이에 맞추기 위해서는 베인핀실(130, vane pin seal)의 양끝을 곡면으로 가공해야 하며, 따라서 가공과정에서 어려움이 많다.However, it is important that the vane pin seal 130 is coupled to fit the insertion hole of the vane 120 to be fixed. If the gap does not fit into the insertion hole, steam or gas will leak into the gap, preventing normal and efficient operation. Therefore, it is required to exactly fit each of the insertion holes of one vane 120 and the vanes 120 adjacent thereto. However, the insertion hole of each vane 120 is rounded so that both ends of the vane pin seal 130 must be curved in order to fit therein, and thus, there are many difficulties in the machining process.

또한 일반적으로 베인핀실(130, vane pin seal)은 벨트와 같이 평행한 양단부가 곡면으로 형성되지만, 이러한 곡면을 매끈하게 가공하는 것은 쉬운 일이 아니며, 이러한 어려움은 베인핀실(130, vane pin seal) 자체가 강도높은 재료이기 때문에 더욱 심하게 된다.In addition, the vane pin seal (130, vane pin seal) is generally formed in both ends parallel to the curved surface, such as a belt, it is not easy to process such a curved surface, this difficulty is the vane pin seal (vane pin seal) (130) It is even worse because it is a hard material itself.

아울러 종래의 방법과 구별되는 또 다른 특별한 가공방법을 통하여 곡면 등과 같이 가공하기 어려운 형태의 부품을 보다 쉽게 가공할 수 있다면, 가공단가를 줄이고 경제성을 갖추며 생산성을 높이는데 기여할 것이다.In addition, if it is possible to more easily process parts of a difficult form, such as curved surface through another special processing method that is distinguished from the conventional method, it will contribute to reducing the processing cost, economical efficiency and increase productivity.

따라서 전술한 문제점을 해결하기 위한 본 발명의 목적은, 효과적인 방법으로 가공을 수행함으로써 생산성과 가공의 경제성을 갖춘 베인핀실(vane pin seal)을 제공하기 위한 것이다.Accordingly, an object of the present invention for solving the above problems is to provide a vane pin seal with productivity and economical efficiency by performing processing in an effective manner.

또한 본 발명의 또 다른 목적은, 수동으로 곡면을 가공하거나 성형함으로써 질높은 구성품을 생산하기 곤란했던 종래의 문제점을 해결하기 해결책을 제시하기 위한 것이다. Still another object of the present invention is to provide a solution to the conventional problem that it is difficult to produce high quality components by manually processing or molding curved surfaces.

아울러 새로운 가공방법을 통해 베인핀실(vane pin seal)을 효과적으로 가공할 수 있는 기술을 제공함에 있다. In addition, the new processing method provides a technology that can effectively process the vane pin seal (vane pin seal).

도시한 바와 같이, 본 실시예의 핀실가공용 롤커터(roll cutter)를 이용한 베인핀실의 가공을 진행하기 위해서는, 먼저 베인핀실(30, vane pin seal)의 가공에 알맞도록 핀실가공재를 일정 크기로 잘라 준비하는 핀실가공재 준비단계가 진행된다. As shown in the drawing, in order to proceed with the processing of the vane pin thread using the pin cutter roll cutter of the present embodiment, first, the pin thread processing material is cut into a predetermined size so as to be suitable for the processing of the vane pin seal 30. The pin thread processing material preparation step proceeds.

즉 보드판과 같은 넓은 판형태의 핀실가공재를 가공하고자 하는 베인핀실(30, vane pin seal)의 크기 즉, 본 실시예에서와 같이 길이 278mm × 폭 15mm 정도나 이 보다 약간 큰 크기로 잘라 낸다(P502).That is, the size of the vane pin seal (30, vane pin seal) to be processed into a wide plate-like pin thread processing material such as a board plate, that is, cut to a size of about 278 mm long × 15 mm wide or slightly larger than in this embodiment (P502) ).

Therefore, it may be prepared by cutting the length side edges in a triangular shape in advance in the preparation process of the pin thread processing material. When the longitudinal side edges are first cut in a triangular manner, the finishing step does not have to be cut in the longitudinal side, and this process may be selectively performed (P504).

이 후 준비된 핀실가공재를 가공머신에 고정시킨 후, 핀실(pin seal)의 장축 평행단부 곡면단에 상보 대응된 연삭단을 가지고 있는 상기 핀실가공용 롤커터(roll cutter)로, 상기 고정된 핀실가공재의 각 측면을 회전가공하여 초벌 핀실을 형성하는 초벌 핀실 가공단계를 진행하게 된다.After fixing the prepared pin thread processing material to the processing machine, the pin thread processing roll cutter having a grinding edge complementary to the curved end of the long axis parallel end of the pin seal (pin seal) of the fixed pin thread processing material Each side is rotated to form a first pin yarn to form a first pin yarn.

즉 이 단계에서는 먼저 일정크기로 잘라 준비된 핀실가공재를 가공머신에 고정시킨다(P506). 아울러 가공할 베인핀실(30, vane pin seal)의 곡면단(310)에 맞는 롤커터(20, roll cutter) 역시 가공머신의 회전축에 장착한다(P508).That is, in this step, first, the pin yarn processing material is cut to a predetermined size and fixed to the processing machine (P506). In addition, a roll cutter 20, which is fitted to the curved end 310 of the vane pin seal 30 to be processed, is also mounted on the rotating shaft of the processing machine (P508).

이 후 장착된 롤커터(20, roll cutter)를 가동시켜 고정시킨 핀실가공재의 일측단면을 가공하고, 이 후 반대측 단면도 가공하여 미완성 상태의 초벌 핀실을 형성을 형성한다(P510).Thereafter, one side surface of the pin thread processing material which is fixed by operating the mounted roll cutter 20 is processed, and thereafter, cross-sectional side processing is performed to form a pristine pin thread in an unfinished state (P510).

또한 도 6의 베인핀실(30, vane pin seal)은 가운데 부분이 전부 평평하게 연삭되어 있는 형태이지만, 필요에 따라서 중간부위의 중간 가공을 수행하지 않을 수도 있으며, 이는 전체 가공과정에서 가공이 불필요한 부분은 가공을 수행하지 않음으로써 가능하다.In addition, although the vane pin seal 30 of FIG. 6 has a shape in which all of its center parts are ground flat, the intermediate parts of the vane pin seals may not be subjected to intermediate machining as necessary. Is possible by not performing the machining.

따라서 이 후 이러한 초벌핀실에 필요한 개수 만큼 일정한 간격으로 곡면마디(310k)를 형성한다(P512). 이러한 곡면마디(310k)도 필요에 따라 추가 가공해 주는 부분으로, 도 6 (A)와 같이 형성시킬 곡면마디(310k) 위치에서 앞면이나 뒷면 혹은 앞뒷면 모두 곡면부분을 떼어내는 형태로 가공할 수도 있으며, 도 6 (B)와 같이 형성시킬 곡면마디(310k) 위치를 전부 혹은 부분적으로 회전해가며 제거하는 방식으로 가공할 수도 있다. Therefore, after this, the curved nodes 310k are formed at regular intervals as many as necessary for the pristine pin chamber (P512). The curved section 310k may be further processed as necessary, and may be processed in the form of removing the curved section at the front, rear, or front and back surfaces at the curved section 310k to be formed as shown in FIG. 6 (A). In addition, the curved node 310k to be formed as shown in FIG. 6 (B) may be processed in such a way that the whole or part is rotated and removed.

이렇게 하여 곡면마디(310k)가 완성되면, 전체적인 크기 및 가공표면 상태 등을 다시 한번 확인하고 특히 중간 가공과정에서 길이측 단부모서리를 삼각형태로 절단하지 않는 경우는 본 과정에서 절단하여 마무리하는 등, 최종 마무리 처리를 수행하여 본 실시예에 따른 베인핀실(30, vane pin seal)을 완성한다(P514).In this way, when the curved node 310k is completed, the overall size and the surface state of the processing are once again checked, and in particular, in the case of not cutting the length side edges in a triangular shape during the intermediate processing, the cutting is finished in this process. The final finishing process is performed to complete the vane pin seal 30 according to the present embodiment (P514).
