본 발명은 이종 금속을 접합하는 장치 및 그 방법에 관한 것으로서, 더욱 상세하게는 이중 금속 중에서 선택된 어느 하나의 금속을 이중확관으로 성형하여 용접부재가 녹을 때 외부로 흘러내리지 않도록 하는 이종 금속 접합 장치 및 그 방법에 관한 것이다.The present invention relates to a device for joining dissimilar metals and a method thereof, and more particularly, to dissimilar metal joining devices for forming any one metal selected from a double metal into a double expansion pipe so as not to flow out when the welding member is melted. It's about how.

잘 알려진 바와 같이, 구리 계열과 스테인리스 계열 또는 구리 계열과 알루미늄 계열 등 기타 이종 금속을 접합(즉, 땜납)할 때 각 금속의 용융점이 서로 다르기 때문에 고주파 용접 또는 브레이징 용접시 이들의 접합이 불가능하였다. 이하 본 발명에서는 발명의 이해를 돕기 위하여 구리 금속과 알루미늄 금속을 접합할 때의 용접 장치 및 그 방법을 구체적으로 제시할 것이다.As is well known, when joining (i.e., soldering) other dissimilar metals such as copper-based and stainless-based or copper-based and aluminum-based, the melting points of the respective metals are different from each other, and thus they cannot be joined during high frequency welding or brazing welding. Hereinafter, the present invention will be described in detail a welding apparatus and a method for joining a copper metal and an aluminum metal in order to facilitate understanding of the invention.

이종 금속을 접합할 때, 구리 금속은 온도가 1000℃ 이상이 되면 녹게 되는데 알루미늄 금속은 낮은 온도에서 녹아내리는 관계로 사실상 이들의 접합은 불가능하였다. 이때 상기 구리(Cu) 금속은 녹는점이 1084.5℃이고, 알루미늄(Al) 금속은 660.4℃이다.When joining dissimilar metals, the copper metal melts when the temperature is above 1000 ° C. Since the aluminum metal melts at a low temperature, the bonding thereof is virtually impossible. In this case, the copper (Cu) metal has a melting point of 1084.5 ° C, and the aluminum (Al) metal is 660.4 ° C.

즉, 구리계 금속과 알루미늄계 금속은 접합 가능한 온도 변화가 매우 커서 700℃ 이하에서는 알루미늄 금속이 먼저 녹게 되고 구리 금속은 그대로 있기 때문에 용접 작업이 제대로 이루어지지 않을 뿐만 아니라 용접시에 별도의 후락스를 사용해야만 하는 접합이 가능하였다. 이로 인해 작업조건이 매우 까다롭고 작업시간 및 비용이 증가되며, 또한 작업환경이 좋지못할 뿐만 아니라 환경오염을 유발시키는 단점이 있었다.In other words, the copper metal and the aluminum metal have a very high temperature changeable to join, so that the aluminum metal melts first at 700 ° C or lower, and the copper metal remains as it is. Bonding that must be used was possible. As a result, the working conditions are very demanding, the working time and cost are increased, and the working environment is not only good, but also has the disadvantage of causing environmental pollution.

특히, 종래에는 이종 금속의 파이프를 서로 접합할 때 용접부재가 파이프의 외부표면을 따라 흘러내리는 현상이 발생하게 되고, 이에 따라 접합부위에는 녹아있는 용제가 부족하여 용접이 제대로 이루어지지 않고 또한 파이프의 외면이 지저분해지는 문제점이 있었다.In particular, when joining pipes of dissimilar metals with each other, a phenomenon in which a welding member flows down along the outer surface of the pipe occurs, and thus, the welded part is insufficiently welded due to lack of dissolved solvent in the joint and also the outer surface of the pipe. There was this messing problem.

따라서, 본 발명은 위와 같은 문제점을 해결하기 위한 것으로, 그 목적은 이종 금속을 접합할 때 용접부재가 금속의 외부표면으로 흘러내리는 것을 방지할 수 있는 이종 금속 접합 장치 및 방법을 제공함에 있다.Accordingly, the present invention is to solve the above problems, an object of the present invention is to provide a dissimilar metal bonding apparatus and method that can prevent the welding member from flowing down to the outer surface of the metal when bonding dissimilar metal.

또한 본 발명의 다른 목적은 용융점이 서로 다른 구리 금속과 알루미늄 금속을 용접할 수 있는 장치 및 방법을 제공함에 있다.Another object of the present invention is to provide an apparatus and method for welding a copper metal and an aluminum metal having different melting points.

상기한 바를 달성하기 위한 제1 견지에 있어 본 발명은, 이종 금속 중에서 선택된 어느 하나의 금속 끝부분에 이중확관을 형성하며, 전류를 인가받기 위한 전극판이 양측으로 각각 부착된 고주파 기계와, 상기 각 전극판에 부착되고 상기 이중확관이 형성된 금속을 가열하기 위한 코일부가 일체로 형성된 가열파이프와, 상기 이중확관에 안착되어 상기 이종 금속을 접합시키기 위한 용접부재로 구성된 이종 금속 접합장치를 제안한다.In a first aspect to achieve the above, the present invention is a high frequency machine that forms a double expansion tube at any one of the metal end selected from the dissimilar metal, the electrode plate for applying a current is attached to both sides, respectively, Disclosed is a heterogeneous metal bonding apparatus comprising a heating pipe integrally attached to an electrode plate and a coil part for heating a metal having the double expansion pipe formed therein, and a welding member mounted on the double expansion pipe to bond the dissimilar metal.

또한 상기한 바를 달성하기 위한 제2 견지에 있어 본 발명은, 이종 금속 중 에서 선택된 어느 하나의 금속의 끝부분을 이중확관으로 성형한 다음, 상기 확관부분에 다른 금속을 삽입하고 끝부분에 용접부재를 안착시킨 후, 상기 이중확관이 형성된 금속을 가열하여 열전도에 의해 상기 용접부재가 녹아내리도록 하여 상기 이종 금속을 접합하는 과정으로 이루어지는 방법을 제안한다.In addition, in a second aspect to achieve the above, the present invention, the end of any one metal selected from the dissimilar metal is formed into a double expansion pipe, then inserting another metal in the expansion pipe portion and the welding member at the end After seating the, and the double-expansion tube is formed by heating the metal to melt the welding member by heat conduction to propose a method consisting of the step of bonding the dissimilar metal.

이하 본 발명의 실시 예를 첨부된 도면을 참조하여 설명하면 다음과 같다. 후술 될 상세한 설명에서는 상술한 기술적 과제를 이루기 위해 본 발명에 있어 한 개의 대표적인 실시 예를 제시할 것이다. 그리고 본 발명으로 제시될 수 있는 다른 실시 예들은 본 발명의 구성에서 설명으로 대체한다. 도면상에서 동일한 도면부호는 동일한 요소를 지칭한다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. DETAILED DESCRIPTION In the following detailed description, one exemplary embodiment of the present invention will be presented to accomplish the above technical problem. And other embodiments that can be presented with the present invention are replaced by the description in the configuration of the present invention. Like reference numerals in the drawings refer to like elements.

한편, 본 발명에서 사용되고 있는 '이종 금속'이라는 용어는 서로 다른 성질을 가지는 금속으로서, 바람직하게는 용융점이 서로 다른 금속을 의미한다. 예를 들어, 구리계 금속과 스테인레스계 금속 또는 구리계 금속과 알루미늄계 금속을 말한다. 이때 상기 구리계 금속은 순수한 구리뿐만 아니라 황동이나 청동과 같이 구리 성분을 함유하고 있는 금속을 의미한다.On the other hand, the term 'different metal' used in the present invention is a metal having different properties, preferably means a metal having a different melting point. For example, a copper metal and a stainless metal, or a copper metal and an aluminum metal. In this case, the copper-based metal refers to a metal containing a copper component such as brass or bronze as well as pure copper.

본 발명에서는 이종 금속을 접합할 때 용접부재가 금속의 외부표면을 타고 흘러내리는 것을 방지함과 아울러 용융점이 서로 다른 이종 금속에 용접부재를 끼우고 고주파 기계를 이용하여 용접부재를 서서히 녹이면서 상기 이종 금속을 접합시키는 장치 및 방법을 구현하고자 한다.The present invention prevents the welding member from flowing down the outer surface of the metal when joining dissimilar metals, while inserting the welding member into dissimilar metals having different melting points, and slowly dissolving the welding member using a high frequency machine. An apparatus and method for joining metals are intended.

도 1은 본 발명의 바람직한 일 실시 예에 따른 이종 금속을 접합시키기 위한 장치를 보이고 있는 도면이다. 본 발명의 접합장치는 용융점이 서로 다른 금속을 각각 가열하기 위한 가열파이프(16) 및 상기 가열파이프(16)에 전류를 공급하는 전극판(12a,12b)으로 구성된 고주파 기계(10)와, 끝부분에 이중확관부(26,28)를 가지는 금속재질의 파이프(24)로 구성된다.1 is a view showing a device for bonding dissimilar metals according to an embodiment of the present invention. The bonding apparatus of the present invention is a high frequency machine (10) consisting of a heating pipe (16) for heating a metal with different melting points, and electrode plates (12a, 12b) for supplying current to the heating pipe (16), It consists of a metal pipe 24 having a double dilatation section 26, 28 at its portion.

상기 도 1을 참조하면, 고주파 기계(10)는 절연체를 중심으로 양측으로 전극판(12a,12b)이 각각 부착되며, 상기 각 전극판(12a,12b)에는 외부로부터 전류를 인가 받기 위한 전도체 재질의 가열파이프(16)가 부착된다. 상기 가열파이프(16)의 일측단에는 냉각수를 공급하기 위한 냉매공급관(14a)이 연결되고, 타측단에는 냉각수를 배출하기 위한 냉매배출관(14b)이 연결된다.Referring to FIG. 1, in the high frequency machine 10, electrode plates 12a and 12b are attached to both sides of an insulator, respectively, and each electrode plate 12a and 12b is a conductor material for receiving current from the outside. Heating pipe 16 is attached. One end of the heating pipe 16 is connected to the refrigerant supply pipe (14a) for supplying the cooling water, the other end is connected to the refrigerant discharge pipe (14b) for discharging the cooling water.

이때, 상기 냉각수는 가열파이프(16)를 계속해서 순환하게 되며, 이는 고열로 인해 가열파이프(16)가 손상되는 것을 방지하기 위함이다. 즉, 상기 가열파이프(16)의 끝부분에 형성된 코일부(18)가 높은 온도까지 상승하는 것을 방지하기 위해 이들을 식혀주는 역할을 한다.At this time, the cooling water continues to circulate the heating pipe 16, in order to prevent the heating pipe 16 from being damaged due to high heat. That is, in order to prevent the coil portion 18 formed at the end of the heating pipe 16 to rise to a high temperature, it serves to cool them.

이와 같은 가열파이프(16)는 각 도면에서 보는 바와 같이, 2회 정도 감겨진 코일부(18)가 형성되고, 상기 코일부(18)는 끝부분에 확관부(26,28)가 형성된 제2 파이프(24)를 가열하는 역할을 한다. 즉, 상기 코일부(18)는 제2 파이프(24)를 가열하게 되는데, 이때 제2 파이프(24)에 가해진 고온의 열은 전도(열전도 방식)에 의해 용접부재(22)에 전달되고, 상기 용접부재(22)는 제2 파이프(24)의 내부로 녹아내리게 된다. As shown in each drawing, the heating pipe 16 has a coil part 18 wound about twice, and the coil part 18 has a second pipe part 26 and 28 formed at an end thereof. It serves to heat the pipe 24. That is, the coil unit 18 heats the second pipe 24, wherein the high temperature heat applied to the second pipe 24 is transmitted to the welding member 22 by conduction (heat conduction method). The welding member 22 is melted into the second pipe 24.

한편, 본 발명에서는 이종 금속을 접합할 때 용접부재(22)가 녹아 금속 표면을 타고 흘러내리는 것을 방지하기 위하여 이중 금속 중에서 어느 하나를 선택하여 이중확관부를 형성하였다. 즉, 알루미늄 금속으로 된 제1 파이프(20)는 그대로 두고, 구리 금속으로 된 제2 파이프(24)의 끝부분을 1차적으로 확장시켜 삽입확관부(26)를 형성하고, 상기 삽입확관부(26)의 끝부분을 다시 2차적으로 확장시켜 단부확관부(28)를 형성한다.Meanwhile, in the present invention, in order to prevent the welding member 22 from melting and flowing down the metal surface when joining dissimilar metals, one of the double metals is selected to form a double expansion pipe. That is, the first pipe 20 made of aluminum metal is left as it is, and the end portion of the second pipe 24 made of copper metal is first expanded to form an insertion enlarged portion 26, and the insertion expanded portion ( The end of 26 is again secondarily expanded to form an end dilator 28.

이때 도 2에 도시한 바와 같이, 상기 삽입확관부(26)에는 제1 파이프(20)의 일부분이 삽입되어 밀착되며, 상기 단부확관부(28)에는 용접부재(22)가 안착된다. 이러한 구성에 따라, 용접부재(22)는 고열에 의해 녹아내려도 제2 파이프(24)의 외부표면을 따라 흘러내리지 않고 단부확관부(28)의 내부(A) 쪽으로 흘러들어가게 된다. 여기서 상기 용접부재(22)는 SU-TC 170 재질을 사용하는 것이 바람직하다.In this case, as shown in FIG. 2, a portion of the first pipe 20 is inserted into and closely contacted with the insertion expansion pipe 26, and a welding member 22 is seated in the end expansion pipe 28. According to this configuration, the welding member 22 flows into the inner portion A of the end expanding portion 28 without flowing down the outer surface of the second pipe 24 even when melted by high heat. Here, the welding member 22 is preferably made of a SU-TC 170 material.

이하, 상기한 바와 같이 구성된 본 발명의 이종 금속 접합방법을 도 2 및 도 3을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the heterogeneous metal bonding method of the present invention configured as described above will be described in detail with reference to FIGS. 2 and 3.

우선 도 2에 도시한 바와 같이, 제2 파이프(24)의 끝부분을 이중확관부{즉, 삽입확관부(26)와 단부확관부(28)} 형태로 성형한 다음, 상기 삽입확관부(26)에 제1 파이프(20)를 삽입하여 안치시킨 후, 상기 제1 파이프(20)에 용접부재(22)를 끼워서 단부확관부(28)에 안착시킨다. 이어서 상기 제1,2 파이프(20,24)를 고주파 기계(10)에 부착된 가열파이프(16)에 끼우게 되는데, 구체적으로는 가열파이프(16)의 코일부(18)가 삽입확관부(26)의 아래부분에 위치하도록 끼운다.First, as shown in FIG. 2, the end portion of the second pipe 24 is formed into a double expansion portion (ie, the insertion expansion portion 26 and the end expansion portion 28), and then the insertion expansion portion ( After inserting the first pipe 20 into 26 and placing it, the welding member 22 is inserted into the first pipe 20 and seated on the end expanding portion 28. Subsequently, the first and second pipes 20 and 24 are inserted into the heating pipe 16 attached to the high frequency machine 10. Specifically, the coil part 18 of the heating pipe 16 is inserted into the expansion pipe part ( 26) so that it is located underneath.

이후, 상기 고주파 기계(10)의 전극판(12a,12b)에 전류를 인가하게 되면, 상 기 가열파이프(16)의 끝부분에 형성된 코일부(18)는 상기 전류를 인가받아 상기 제2 파이프(24)을 가열하게 된다. 이에 따라 고온의 열은 상기 제2 파이프(24)의 표면을 따라 단부확관부(28)에 놓여진 용접부재(22) 쪽으로 열전도 방식에 의해 전도되어지게 되며, 결국 상기 용접부재(22)는 서서히 녹으면서 단부확관부(28)의 내부(A)로 유입되어 이종 금속인 제1,2 파이프(20,24)는 서로 접합되어진다.Subsequently, when a current is applied to the electrode plates 12a and 12b of the high frequency machine 10, the coil unit 18 formed at the end of the heating pipe 16 receives the current to receive the second pipe. (24) is heated. Accordingly, the high temperature heat is conducted by the heat conduction method toward the welding member 22 placed on the end expansion portion 28 along the surface of the second pipe 24, and the welding member 22 gradually melts. The first and second pipes 20 and 24, which are different metals, are introduced into the interior A of the end expanding portion 28 while being joined to each other.

이상으로 살펴본 바와 같이, 본 발명은 이종 금속을 접합시킬 때 용접부재가 녹아서 금속 외부표면으로 흘러내리는 것을 방지할 수 있으며, 이에 따라 용접 부위가 매끄럽고 깨끗하여 별도의 후처리 공정이 필요없는 장점이 있다. 뿐만 아니라 별도의 후락스를 사용하지 않고 이종 금속을 용접할 수 있기 때문에 접합력을 높일 수 있는 효과가 있다.As described above, the present invention can prevent the welding member from melting and flowing down to the outer surface of the metal when joining dissimilar metals, and thus, the welded portion is smooth and clean, which does not require a separate post-treatment process. . In addition, since it is possible to weld dissimilar metals without using a separate flax, there is an effect of increasing the bonding strength.
