Description

고주파 건{HIGH FREQUENCY GUN}High Frequency Gun {HIGH FREQUENCY GUN}

본 발명은 고주파 건에 관한 것으로, 보다 상세하게는 휴대의 용이성, 이동의 편의성을 갖추어 냉장고, 에어컨 등의 조립라인에서 브레이징된 동관을 더욱 안정적으로 씰링하는 밀봉 작업에 유용하게 활용될 수 있도록 개선된 고주파 건에 관한 것이다.
The present invention relates to a high frequency gun, and more particularly, it is improved to be useful for sealing work for more stably sealing a brazed copper tube in an assembly line such as a refrigerator and an air conditioner with ease of portability and mobility. It is about a high frequency gun.

일반적으로, 금속을 결합시킬 때는 용접이나 납땜에 의한 결합을 이루는 것이 대부분이다.In general, when joining metals, the joining is usually performed by welding or soldering.

이 중에서도, 동(Cu)과 같은 경금속의 접합에는 납땜이 많이 활용되며, 납땜 중에서도 특히, 브레이징(Brazing)이 주로 활용된다.Among these, soldering is used a lot for joining light metals, such as copper, and brazing is especially utilized among soldering.

즉, 브레이징은 납땜의 한 종류로서, 접합하려는 모재보다도 녹는점이 낮은 비철금속 또는 그 합금(납재)을 용가재로 사용하여 모재를 거의 용융시키지 않고 납재만을 용융시켜 접합하는 접합 방법을 말한다.In other words, brazing is a type of soldering, in which a nonferrous metal or an alloy (lead material) having a lower melting point than a base material to be joined is used as a filler material, and a bonding method is performed by melting only the brazing material with little melting of the base material.

이러한 브레이징은 특히, 냉장고나 에어컨 등의 냉매파이프를 접합하는데 많이 사용해 왔다.Such brazing has been particularly used for joining refrigerant pipes such as refrigerators and air conditioners.

그런데, 브레이징 접합부가 균질성을 갖지 못하여 균열, 홈 등이 발생하는 등의 단점이 있다. 이는 안정된 열처리에 의하여 형성된 접합면이 아니기 때문이며, 따라서 접합강도면에서도 일정 수준 이상의 접합강도를 갖기 어렵다.However, there is a disadvantage in that the brazing joint does not have homogeneity and cracks, grooves, and the like occur. This is because it is not a joint surface formed by a stable heat treatment, and therefore it is difficult to have a bond strength of a certain level or more even in the joint strength surface.

이와 같은 이유 때문에 냉장고 혹은 에어컨 조립라인에서는 브레이징된 접합부를 토치로 열을 가해 안정적인 열처리 공정을 거치고 있으며, 이를 통해 접합면에서의 접합강도를 향상시키고 있다.For this reason, the refrigerator or air conditioner assembly line is subjected to a stable heat treatment process by applying a brazed joint to the torch, thereby improving the bonding strength at the joint surface.

하지만, 토치를 사용할 경우 숙련공에 따라 처리품질이 달라져 품질 편차가 크고, 토치 사용시 가열해야 할 부분 주변의 합성수지를 녹여 버려 제품 불량을 유발하며, 또 작업시마다 토치를 들고 라인스피드에 맞춰 일정구간 왕복이동을 반복해야 하므로 작업이 어렵고 힘들 뿐만 아니라, 안전사고의 위험도 높았다.However, if the torch is used, the processing quality varies depending on the skilled worker, and the quality variation is large. When using the torch, the synthetic resin around the part to be heated is melted, causing product defects. Because of the repetition, the work was difficult and difficult, and the risk of safety accidents was high.

이에, 이를 개선하기 위한 일환으로 고주파 유도가열방식의 열처리가 가능한 기술이 개시되었는데, 이와 관련된 것으로 예컨대, 공개특허 제2012-0010429호를 들 수 있다.Thus, as a part of improving the technique has been disclosed a technology capable of heat treatment of the high frequency induction heating method, for example, there is related to, for example, Patent Publication No. 2012-0010429.

상기 공개특허에 도시된 도 1 및 도 6을 참조하면, 고주파 유도가열형 지그를 이용하여 와전류 손실과 히스테리손실을 주울열로 바꾸는 작용을 하는 고주파 유도가열방식으로 단시간에 대상물을 가열하여 원하는 열처리를 할 수 있는 매우 유용한 기술이라 할 수 있다.Referring to FIGS. 1 and 6 shown in the above-mentioned patent, a high frequency induction heating method of converting eddy current loss and hysteresis loss into Joule heat by using a high frequency induction heating type jig to heat an object in a short time to perform a desired heat treatment. It's a very useful technique.

그러나, 개시된 특허 기술을 비롯하여, 지금까지 알려진 고주파 유도가열 기술은 주로 유닛(고주파 유도가열 지그)이 하우징에 고정된 타입이기 때문에 이동성, 휴대성에 있어 매우 제한적이었다.However, the high frequency induction heating technology known to date, including the disclosed patented technology, has been very limited in terms of mobility and portability since the unit (high frequency induction heating jig) is mainly a type fixed to the housing.

뿐만 아니라, 공개특허에 개시된 형태에서도 알 수 있듯이, 부재와 부재가 단품 형태일 때만 가능할 뿐 이미 조립라인에서 조립된 상태에 있는 부재들을 가열처리하는 것은 사실상 불가능하였으므로, 이를 냉장고 또는 에어컨 조립라인에서 사용할 수는 없었다.In addition, as can be seen in the form disclosed in the patent application, it is only possible when the member and the member are in the form of a single unit, and since it was virtually impossible to heat-treat the members that are already assembled in the assembly line, it can be used in a refrigerator or air conditioner assembly line. There was no number.

이는, 조립된 상태에 있는 부재들은 상기 공개특허에 개시된 지그에 끼울 수 없기 때문에 사실상 작업이 불가능하고, 또한 대부분 유닛이 고정형 하우징에 설치되어 있기 때문에 유닛 자체를 작업라인의 공정속도에 맞춰 이동시킬 수 없는 이유이기도 하다.
This means that the members in the assembled state are virtually impossible to work with because they cannot fit in the jig disclosed in the above patent application, and since the unit is installed in the fixed housing, the unit itself can be moved at the process speed of the work line. That's why.

본 발명은 상술한 바와 같은 종래 기술이 갖는 한계점과 문제점을 모두 고려하여 이를 한번에 해결할 수 있도록 창출된 것으로, 고주파 유도가열 기능을 갖출 수 있도록 유닛을 건(Gun) 형태로 만들고, 조립라인에서도 사용할 수 있도록 가열부인 워크코일의 일부를 홈 형태로 절곡 가공하여 조립된 부품일지라도 그 상태에서 단순히 끼워 사용할 수 있으므로 휴대의 용이성, 사용상 편의성을 모두 만족시킬 수 있는 고주파 건을 제공함에 그 주된 목적이 있다.

도 1 내지 도 3에 도시된 바와 같이, 본 발명에 따른 고주파 건은 몸체(100)와 손잡이(110)를 포함한 건(Gun) 형태로 이루어진다.As shown in Figures 1 to 3, the high frequency gun according to the invention is made in the form of a gun (Gun) including a body 100 and the handle 110.

이때, 상기 몸체(100)의 일측, 정확하게는 선단면에는 워크코일(210)을 갖는 가열부재(210)가 탈착가능하게 접속되고, 상기 손잡이(110)에는 작동스위치(112)가 구비된다.At this time, the heating member 210 having the work coil 210 is detachably connected to one side of the body 100, and the front end face thereof, and the handle 110 is provided with an operation switch 112.

또한, 상기 워크코일(210)에는 센터링가이드(220)가 구비되어 있어 피가열물이 정확하게 센터링되도록 안내하므로 가열효율이 더욱 더 증진된다.In addition, the work coil 210 is provided with a centering guide 220 to guide the heating object to be accurately centered, thereby further improving heating efficiency.

뿐만 아니라, 상기 워크코일(210)은 단시간에 고열을 발생시킬 수 있도록 자속 집중을 유도하기 위해 페라이트코어로 구성됨이 바람직하다.In addition, the work coil 210 is preferably composed of a ferrite core to induce the concentration of magnetic flux to generate high heat in a short time.

따라서, 작업자는 손잡이(110)를 파지한 상태에서 가열부재(210)에 구비된 워크코일(210)의 요입된 부분은 피가열물에 삽입한 다음 작동스위치(112)를 누르면 상기 워크코일(210)에서 고주파 유도가열이 일어나면서 피가열물을 국부적으로 단시간에 고열로 가열하게 되어 아주 짧은 시간에 아주 편리한 방식으로 열처리가 가능해진다.Therefore, the worker inserts the recessed portion of the work coil 210 provided in the heating member 210 while holding the handle 110 is inserted into the heating object and then pressing the operation switch 112, the work coil 210 High frequency induction heating occurs at) and the heated object is heated to high temperature locally in a short time, which enables heat treatment in a very convenient manner in a very short time.

여기에서, 고주파 유도가열이란 전자유도작용을 이용하여 워크코일(210)에 고주파 전류를 흘려 고주파 자기장이 발생하게 함으로써 이 고주파 자기장 내에 있는 가열물에 유도전류가 흐르도록 하고, 이 유도전류는 물체 내에서 전류가 소용돌이치며 흐르는 와전류에 의해 생기는 손실과, 히스테리시스 손실에 의한 주울열을 아주 짧은 시간에 발생하게 하여 발열되게 하는 가열방식을 말한다.Here, high frequency induction heating means that a high frequency magnetic field is generated by flowing a high frequency current through the work coil 210 by using an electromagnetic induction action so that an induced current flows in a heating material within the high frequency magnetic field, and the induced current is in the object. It refers to the heating method that causes the heat generated by the swirling eddy current flowing in the current and the Joule heat caused by the hysteresis loss in a very short time.

이러한 고주파 유도 가열 방식에 따르면 주파수가 높은 고주파 전류를 사용하기 때문에 전류의 표피작용 및 근접효과에 의해서 피가열물의 표면층에 자속 및 와전류가 집중하며 이때 발생하는 열손실(와전류 손실, 히스테리시스 손실)이 피가열물의 표면층을 가열하게 되는 것이다.According to this high frequency induction heating method, since high frequency current with high frequency is used, the magnetic flux and eddy current are concentrated on the surface layer of the heated object due to the skin action and proximity effect of the current, and the heat loss (eddy current loss, hysteresis loss) generated at this time is avoided. The surface layer of the heating material is heated.

한편, 고주파 유도가열시 가열부재(200)를 비롯한 워크코일(210), 그리고 발진을 안내하는 몸체(100) 내부에서는 고열이 발생하므로 이를 냉각시킬 수 있는 냉각수단이 요구된다.On the other hand, since the high temperature is generated in the work coil 210, including the heating member 200, and the oscillation guiding body 100 during the high frequency induction heating, a cooling means capable of cooling it is required.

이에, 본 발명에서는 수냉방식으로 냉각하도록 구성되며, 대부분의 고주파 유도가열 방식의 유닛들이 이 방식을 채택하고 있다.Therefore, in the present invention, it is configured to cool by a water cooling method, and most high frequency induction heating units adopt this method.

때문에, 도 4에서와 같이, 몸체(100)의 내부에는 서로 연통된 다수의 수냉챔버(120)와, 고주파 발진을 위한 유도부재(130)가 내장되고, 이들에는 각각 챔버인렛(122)과 챔버아웃렛(124), 유도부재인렛(132)과 유도부재아웃렛(134)이 구비되는데, 이들은 몸체(100)의 일측에 구비되며, 발진기 및 전원공급원이 마련된 별도의 유닛(미도시)으로부터 인출된 수냉관과 수냉케이블이 각각 접속된다.Therefore, as shown in Figure 4, the interior of the body 100, a plurality of water-cooled chamber 120 and the induction member 130 for high frequency oscillation is built in, these are respectively chamber inlet 122 and chamber The outlet 124, the induction member inlet 132 and the induction member outlet 134 is provided, which is provided on one side of the body 100, the water cooling drawn from a separate unit (not shown) provided with an oscillator and a power supply source The pipe and the water cooling cable are connected respectively.

이때, 상기 수냉관은 냉각수가 흐르는 단순한 관이고, 수냉케이블은 몸체(100) 내부에 설치된 변환기와 접속을 위한 이중관 형태로서 코어에는 통전가능한 케이블이 구비되고 그 외측으로 냉각수가 흐를 수 있도록 된 수밀구조를 갖는 관상체이다.At this time, the water cooling tube is a simple tube through which the cooling water flows, and the water cooling cable is a double tube type for connection with a converter installed inside the body 100, and a core is provided with an electrically conductive cable, and the watertight structure allows the cooling water to flow outward. It is a tubular body having.

본 발명에서 가장 특징적인 사항은 외형이 휴대 가능한 건 형태라는 점과, 냉각구조를 갖추고 있음에도 불구하고 워크코일(210)을 갖춘 가열부재(200)를 장탈착할 수 있도록 구성된 점, 그리고 후술하겠지만 워크코일(210)을 피가열물이 관통한 상태에서 처리되는 구조가 아니라 워크코일(210)을 홈(212) 형태로 절곡 가공하여 절곡되면서 요입된 부분, 즉 상기 홈(212)으로 피가열물이 끼워질 수 있도록 구성(관통하는 것이 아님)한 점에 있다.The most characteristic feature of the present invention is that the external shape is a portable gun form, and having a cooling structure, and configured to mount and detach the heating member 200 having the work coil 210, and will be described later The coil 210 is not a structure that is processed in a state in which the heated object penetrates, but is bent by bending the work coil 210 in the form of a groove 212, and the heated object is inserted into the recessed portion, that is, the groove 212. It is constructed (not penetrated) so that it can be fitted.

이 중, 가열부재(200)를 장탈착하기 위해서는 긴밀한 씰링성을 갖춘 구조가 요구되는데, 이를 위해 본 발명에서는 도 1의 예서와 같이 가열부재(200)의 일단, 즉 워크코일(210) 반대단에 접속볼트(138)와 씰링볼(140)을 순차로 끼운 다음 단부 내경을 약간 확관시키면 상기 접속볼트(138)와 씰링볼(140)이 이탈되지 않게 된다.Among these, in order to mount and detach the heating member 200, a structure having a tight sealing property is required. For this purpose, one end of the heating member 200, that is, the opposite end of the work coil 210, as shown in FIG. If the connecting bolt 138 and the sealing ball 140 is inserted in sequence and the inner diameter of the end is slightly expanded, the connecting bolt 138 and the sealing ball 140 are not separated.

그 상태에서, 가열부재(200)의 일단을 몸체(100)의 유도부재(130)와 연통된 접속너트(136)에 끼운 후 상기 접속볼트(138)를 상기 접속너트(136)에 나사 체결하게 되면 상기 씰링볼(140)이 접속너트(136)와 접속볼트(138) 속으로 들어가면서 압착되어 가열부재(200)를 완벽하게 씰링하게 된다.In that state, one end of the heating member 200 is inserted into the connection nut 136 in communication with the induction member 130 of the body 100, and then the connection bolt 138 is screwed into the connection nut 136. When the sealing ball 140 is pressed into the connection nut 136 and the connection bolt 138 to completely seal the heating member 200.
