본 고안은 고주파 유도열을 이용한 열처리 장치에 사용되는 개방형 고주파 유도코일에 관한 것이다.The present invention relates to an open high frequency induction coil used in a heat treatment apparatus using high frequency induction heat.
고주파유도열을 이용하여 금속 가공물을 가열한후 냉각수로써 급냉시켜 열처리를 행하는 고주파 유도열처리 장치에 사용되는 종래의 유도코일은 유도코일 환체의 양단에 전극봉을 연장설치 한 소위 폐쇄형이 있으므로 단순한 봉재의 열처리시에는 문제가 없으나, 크랭크축이나 양단에 플랜지부가 형성된 부품등의 가공물을 열처리 할 경우에는 상기 환체 폐쇄형의 유도코일을 가공물에 끼울수 없었기 때문에 제4도에 도시한 바와같이 환체 유도코일(51)을 횡방향으로 분할하고 그 하반부(53)의 일측을 힌지로하여 회동 개폐가 가능하도록 설치하고 타측에는 고정볼트(52)로 체결시키게 함으로서, 고정볼크(52)를 풀어, 유도코일(51)을 개방시킨 상태에서 유도코일(51)의 환체내에 가공물을 끼운다음 하반부(53)를 들어올려고정볼트(52)로 체결시키는 소위 개폐형을 사용하고 있었다.Conventional induction coils used in high frequency induction heat treatment apparatuses in which a metal workpiece is heated using high frequency induction heat and then quenched with coolant to perform heat treatment have a so-called closed type in which electrodes are extended on both ends of an induction coil ring. There is no problem in heat treatment, but when heat-treating a workpiece such as a crank shaft or a component having a flange portion at both ends, the induction coil of the closed ring type was not able to be inserted into the workpiece. Splitting the 51 in the lateral direction and installed so as to be able to rotate opening and closing with one side of the lower half (53) as a hinge, and to the other side by fastening with a fixing bolt 52, to release the fixed bolt 52, induction coil (51) The so-called dog which inserts the workpiece into the annulus of the guide coil 51 in the state of opening) and then fastens it with the fixing bolt 52 to lift the lower half 53. It was using a type.
그러나 이러한 구조의 유도코일은 열처리 준부 및 분리회수 작업즉, 코일환체에 가공물을 끼우고 빼내는 작업에 고정볼트(52)를 풀고 조이는 작업이 개재되므로 번거롭고 작업시간을 지연시키는등 작업능률을 저하시키는 문제점을 내재하고 있었다.However, the induction coil of such a structure is cumbersome and delays the work time because the work of loosening and tightening the fixing bolt 52 is included in the heat-treatment part and the separate recovery work, ie, inserting and removing the workpiece into the coil ring. The problem was inherent.
따라서 본 고안은 이러한 종래의 제반문제점을 해소하기 위하여 안출된 것으로, 그 특징은 유도코일의 하부를 완전개방되도록 형성시킴으로써 가공물의 끼움과 분리를 유도코일의 승강운동을 할 수 있는 구조의 유도코일을 제공하여 작업편리함과 작업시간을 단축시킬수 있도록 하는 데 그 목적이 있는 것이다.Therefore, the present invention has been devised to solve such a conventional problem, and its feature is to form the lower part of the induction coil to be completely open, so that the fitting and separation of the workpiece can be lifted by the induction coil structure. The purpose is to provide convenience and shorten the working time.
이하, 본 고안을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도시한 바와같이, 말굽형수직부(2)와 사각형수직부(3)를 수평연결부(4)로 연결하여 일체로 형성된 코일 본체(1)의 상단양측에 전극(5)을 연결설치하고, 연결부(4)에는 각 한쌍의 실리콘 마그네트 코어(6)를 끼웠으며, 양코어(6)의 사이에는 브라켓트(7)를 끼워외측으로 연장설치하고, 브라켓트(7)에 나사체결되는 절연봉(8)의 단부에는 장착판(9)을 나사체결하고 그 상하 내측면에 냉각수 분사관(10)을 설치하여서 된 것이다.As shown in the drawing, the horseshoe vertical portion 2 and the rectangular vertical portion 3 are connected to the horizontal connection portion 4 by connecting the electrodes 5 on both sides of the upper end of the coil body 1 integrally formed, and the connection portion ( 4) a pair of silicon magnet cores 6 are fitted, and between the cores 6, brackets 7 are inserted and extended outwards, and the insulating rods 8 screwed to the brackets 7 are provided. The mounting plate 9 is screwed into the end and the cooling water injection pipe 10 is provided on the upper and lower inner surfaces thereof.
미설명부호(11)은 코일본체(1)내에 천설된 냉각수 통로이고, (12)는 분사공, (13)은 냉각수 공급관이며, (14)(15)는 체결나사이며, (16)은 가공물이다.Reference numeral 11 denotes a cooling water passage established in the koja body 1, 12 is a spray hole, 13 is a cooling water supply pipe, 14 is a tightening screw, and 16 is a workpiece. to be.
이러한 구성의 본 고안의 유도 코일을 이용하여 고주파 유도 열처리를 행함에 있어서는 제2도에 도시한 바와같이, 상기 코일 본체(1)를 위로부터 하강시켜 코일본체(1)내에 가공물(16)을 삽입하되 연결부(4)가 가공물(16)의 중심과 일치토록 한 상태에서 전극(5)에 전원을 인가하면 본체(1)에서 고주파 유도열이 발생하여 가공물(16)을 가열하게 되는 것이다.In performing the high frequency induction heat treatment using the induction coil of the present invention having such a configuration, as shown in FIG. 2, the coil body 1 is lowered from above and the workpiece 16 is inserted into the nose piece 1. However, when the connecting portion 4 is applied to the electrode 5 in a state that is in agreement with the center of the workpiece 16, the high frequency induction heat is generated in the main body 1 to heat the workpiece 16.
이때 가공물(16)은 회전시키며, 코일본체(1)는 일정 속도로 측방이동 시킨다.At this time, the workpiece 16 rotates, and the nose body 1 moves laterally at a constant speed.
가공물이 소정 온도로 가열되면 냉각수 분사관(10)의 분사공(13)을 통해 냉각수를 분사하여 급냉시키는 것이다.When the workpiece is heated to a predetermined temperature is to quench the cooling water by spraying the cooling water through the injection hole 13 of the cooling water injection pipe (10).
열처리가 완료되면 코일 본체(1)를 상승시켜 가공물(16)에서 이탈시키며 가공물(16)은 회수한다.When the heat treatment is completed, the coil body 1 is raised to move away from the workpiece 16 and the workpiece 16 is recovered.
상기 열처리 과정중 코일 본체(1)에 가공물(16)의 끼움및 분리에 있어서는 코일 본체(1)를 승강시키는 것에 의해 가공물(16)을 진입 및 이탈시키는 것이므로 제3도와 같이 가공물(16)이 크랭크축인 경우도 매우 신속 간편하게 된다.In the fitting and detachment of the workpiece 16 to the coil main body 1 during the heat treatment, the workpiece 16 enters and exits by lifting the coil main body 1, so that the workpiece 16 cranks as shown in FIG. It is also very quick and easy in the case of an axis.
또한 상기 코일 본체(1)는 개방형이므로 폐쇄형에 비해 유도 효율 및 가열효율의 저하가 고려되나 연결부(4)에 실리콘 마그네트 코어(6)를 끼웠으므로 폐쇄형과 동등이상의 효율을 얻을 수 있는 것이다.In addition, since the coil body 1 is open type, the reduction in induction efficiency and heating efficiency is considered as compared to the closed type, but since the silicon magnet core 6 is inserted into the connection part 4, efficiency higher than or equal to the closed type can be obtained.
이상에서와 같이 본 고안에의하면 코일본체를 개방형으로 하므로써 종래의 개폐형 유도코일과 비교하여 가공물의 삽입및 분리가 용이하며 작업의 편리함과 작업능률의 향상에 기여할 수 있는 고안인 것이다.As described above, according to the present invention, it is easy to insert and separate the workpiece compared to the conventional open / close induction coil by using the Kojapan body as an open type, and it is a device that can contribute to convenience of work and improvement of work efficiency.
