본 고안은 허니콤(honey comb)판 용접장치에 관한 것으로, 특히 허니콤판의 곡면용접에 적합한 용접장치에 관한 것이다.The present invention relates to a honey comb plate welding device, and more particularly to a welding device suitable for curved welding of honeycomb plate.
구(sphere)형이나 원통형등의 셀(shell)구조는 전체적인 강도는 충분하나 얇은 판재로 만들어지므로 국부적인 강도가 취약하다.The shell structure, such as sphere or cylinder, has sufficient overall strength but is weak in local strength because it is made of thin plate.
압력용기등과 같이 그 중량에 크게 제한이 없는 경우에는 판재의 두께를 증가시킴으로써 국부적 변형이나 항복 또는 비클링(buckling)등을 방지할수 있다.If the weight is not particularly limited, such as a pressure vessel, by increasing the thickness of the plate can prevent local deformation, yield or buckling.
그러나 항공기의 동체나 엔진등과 같이 그 중량에 많은 제한이 있는 경우에는, 이 판재의 제1도에 도시된 바와같은 하니콤판을 부착함으로써 국부강도를 증가시키는 것이 통상적인 방법이다. 허니콤판은 도면에서 보인 바와 같이 얇은 판재로 이뤄진 셀(cell ; E)들이 연속하여 형성되어, 셀(E)의 횡방향 외력에 대해서는 약하지만 셀(E)의 종방향으로는 상당한 강도를 발휘하여 판재의 국부강도를 증가시키게 된다. 도시된 하니콤판(H)은 벌집모양으로 이뤄져 있으나 이외에도 원통형 셀이나 사각형 셀 또는 물결형등 여러 가지의 것이 사용된다.However, if there are many restrictions on the weight of the aircraft body, engine, or the like, it is common practice to increase the local strength by attaching a honeycomb plate as shown in FIG. As shown in the drawing, the honeycomb plate is formed by a series of cells (E) made of thin plates, and exhibits considerable strength in the longitudinal direction of the cell (E) although weak against the lateral external force of the cell (E). It will increase the local strength of the plate. The honeycomb plate (H) shown is made of a honeycomb shape, but in addition to the cylindrical cell or rectangular cell or a variety of waves are used.
이와같이 하니콤판은 통상 브레이징(brazing)에 의해 판재에 고정되는데, 이 브레이징에 대신하여 또는 가접(假接)으로서 저항용접을 행하게 된다.In this manner, the honeycomb plate is usually fixed to the plate by brazing, and resistance welding is performed instead of or as a temporary welding.
이와같은 저항용접장치의 종래예를 제2도를 보였는데, 이것은 특히 곡면상의 판재에 하니콤판을 용접하는 장치이다. 도면에서, 곡면형의 판재(P)는 이에 대응하는 곡면 배드(bad)형의 하부전극(12)상에 거치되고, 그 상부에 하니콤판(H)이 얹혀진 뒤, 다시 그 상부로부터(11)이 이를 가압함으로써 저항열이 발생되어 저항용접이 이뤄진다.The conventional example of such a resistance welding apparatus is shown in FIG. 2, which is a device for welding a honeycomb plate to a curved sheet. In the figure, the curved plate P is mounted on the corresponding bad bottom lower electrode 12, and the honeycomb plate H is placed on the top thereof, and then again from the top 11 thereof. By pressurizing this, resistance heat is generated and resistance welding is performed.
그런데 이 저항용접과정은 상부전극(11)이 하니콤판(H)의 각 셀의 에지(edge)를 판재(P)에 적절한 압력으로 가압함과 동시에 동전시켜야 하며, 판재(P)도 하부전극(12)에 밀착되어야 하므로, 상·하부전극(11, 12)에 상당한 가공정도(精度)를 요하게 된다.However, in this resistance welding process, the upper electrode 11 presses the edge of each cell of the honeycomb plate H at the appropriate pressure on the plate P and coin at the same time, and the plate P also has the lower electrode ( 12, the upper and lower electrodes 11, 12 require a considerable degree of processing.
따라서, 상·하부전극(11, 12)은 용접될 판재(P)의 곡률에 따라 각각 전용으로 구성되어야 하므로 용접장치의 소요수가 증가되고, 이에 따라 설치면적도 증가되고 제품의 동선(動線)이 연장되어 생산성도 저하되는 문제가 발생한다.Therefore, since the upper and lower electrodes 11 and 12 must be configured exclusively according to the curvature of the plate material P to be welded, the required number of welding apparatuses increases, so that the installation area also increases and the copper wire of the product is increased. This prolongs the problem of lowering productivity.
한편 정밀한 곡률의 상·하부전극(11, 12)을 제작한다 하더라도 판재(P)와 하니콤판(H)의 거치작업은 수작업으로 이뤄지므로 이를 정확히 거치한다는 것은 거의 불가능하며, 상·하부전극(11, 12)이 하니콤판(H)의 각 셀과 정확히 접촉하는 것도 매우 어렵다.Meanwhile, even if the upper and lower electrodes 11 and 12 of precise curvature are manufactured, the mounting work of the plate material P and the honeycomb plate H is performed by hand, so it is almost impossible to accurately mount the upper and lower electrodes 11. 12) it is also very difficult to accurately contact each cell of the honeycomb plate (H).
상·하부전극(11, 12)과 판재(P) 및 하니콤판(H)이 정확히 거치되어 밀착되지 못하는 경우에는 다음과 같은 여러 가지 문제점이 발생한다.When the upper and lower electrodes 11 and 12, the plate material P, and the honeycomb plate H are not correctly mounted and adhered to each other, various problems occur as follows.
즉, 이들이 정확히 밀착된 경우에는 도면의 A부분의 흑점들과 같이 용접이 이뤄지나, 상·하부전극(11, 12)과 밀착되지 못한 B부분이나 C부분에서는 용접이 이뤄지지 못하게 된다. 더구나 이 밀착되지 못한 갭(gap)사이에서는 고압통전에 의해 스파크(spark)방전이 발생하여 이에따라 얇은 판재로 된 하이콤판(H)이 천공(piercing)되거나 판재(P)에 언더컷(undercut)이 발생되어 강도상 취약부가 될수 있다. 뿐만 아니라 상부전극(11)이 하이콤판(H)을 부분적으로 가압하여 하이콤판(H)을 변형손상시키는 문제점도 발생하게 된다.That is, when they are in close contact with each other, welding is performed as in the black spots of part A of the drawing, but welding is not performed in the part B or C which is not in close contact with the upper and lower electrodes 11 and 12. In addition, spark discharge occurs due to high-pressure energization between the gaps that are not in close contact with each other, so that a thin plate of high-compass plate (H) is piercing or an undercut is generated in the plate (P). It can be a weak part in strength. In addition, the upper electrode 11 partially pressurizes the hi-com plate H, thereby causing a problem of deforming and damaging the hi-com plate H.
본 고안은 상술한 여러 가지 문제점을 해결하기 위해 안출된 것으로, 상·하부전극의 높은 가공정도를 요구하지 않을뿐 아니라 국부변형이나 스파크의 발생등이 없이 균일한 저항용접이 가능한 하니콤판 용접장치를 제공하는 것을 그 목적으로 한다.The present invention was devised to solve the above-mentioned problems, and it does not require a high degree of processing of the upper and lower electrodes, and a honeycomb welding apparatus capable of uniform resistance welding without local deformation or sparking. Its purpose is to provide.
이와같은 목적을 달성하기 위해 본 고안에 따른 하니콤판 용접장치는 상부전극과 하부전극사이에서 하니콤판을 판재에 대해 저항용접하는 하니콤판 용접장치에 있어서, 상부전극과 하부전극의 적어도 하나에, 하니콤판과 판재의 곡률과 가압력을 보상하는 탄성지지수단과, 상부전극과 하부전극을 하니콤판과 판재에 탄성적으로 접촉시켜 통과시키는 탄성전극수단중의 적어도 어느 하나를, 구비하여 구성되는 것을 특징으로 한다.In order to achieve the above object, the honeycomb welding apparatus according to the present invention is a honeycomb welding apparatus for welding a honeycomb plate to a plate between an upper electrode and a lower electrode, at least one of the upper electrode and the lower electrode, And at least one of elastic support means for compensating curvature and pressing force of the comb and the plate, and elastic electrode means for elastically contacting the upper electrode and the lower electrode to the honeycomb and the plate. do.
이하 첨부된 도면을 참조로 하여 본 고안의 원리와 바람직한 실시예를 상세히 설명한다.Hereinafter, the principles and preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제3도에서, 본 고안에 따른 용접장치의 상부전극(1)은 본체(1a)에 탄성지지수단(3)에 의해 결합지지되는 전극헤드(1b)의 선단에 탄성전극 수단(4)이 결합되어 구성된다.In FIG. 3, the upper electrode 1 of the welding apparatus according to the present invention has the elastic electrode means 4 coupled to the front end of the electrode head 1b that is supported by the elastic support means 3 to the main body 1a. It is configured.
탄성지지수단(3)은 하부전극(2)상에 판재(P) 및 하니콤판(H)이 정확히 접촉되도록 이를 가압하는 동시에 편심가압이 이뤄지지 않도록 이를 탄성적으로 보상하는 구실을 하게 된다. 한편 탄성전극수단(4)은 상술한 탄성지지수단(3)의 역할을 보조할 뿐 아니라 하니콤판(H)의 각 셜이 상부전극(1)에 의해 균일하게 통전될수 있도록 하는 구실을 한다.The elastic support means (3) is to press the plate (P) and the honeycomb plate (H) on the lower electrode (2) to exactly contact, while at the same time to serve as an elastic compensation to prevent the eccentric pressure is achieved. On the other hand, the elastic electrode means 4 serves not only to assist the role of the elastic support means 3 described above, but also to allow each shir of the honeycomb plate H to be uniformly energized by the upper electrode 1.
이에 따라 본 고안에 따른 저항용접장치는 상·하부 전극(1, 2)이 고정도로 가공되지 않아도 용접물을 용접가능한 상태로 지지할수 있게 된다. 특히 상부전극(1)은 유사한 곡률범위에 대하여는 범용으로 사용될수 있으므로 용접장치의 소요량을 현저히 감소시킬수 있게 된다. 또한 용접물의 거치가 간편해져서 생산성이 현저히 향상되고 하니콤판(H)이나 판재(P)의 손상등 불량률이 대폭 감소된다.Accordingly, the resistance welding device according to the present invention can support the weldment in a weldable state even when the upper and lower electrodes 1 and 2 are not processed with high accuracy. In particular, since the upper electrode 1 can be used in general for a similar curvature range, it is possible to significantly reduce the requirement of the welding apparatus. In addition, the mounting of the weld becomes simple, the productivity is remarkably improved, and the defective rate such as damage of the honeycomb plate H or the plate P is greatly reduced.
본 고안 용접장치는 제4와 같이 구성될 수도 있다. 즉 본체(1a)와 전극헤드(1b)사이의 탄성지지수단(3)으로서 예를들어 실리콘 고무블록(Silicon rubber block; 3a)이 구비되고, 본체(1a)와 전극헤드(1b)간에는 도선이 연결된다.The present invention welding apparatus may be configured as in the fourth. That is, for example, a silicon rubber block 3a is provided as the elastic support means 3 between the main body 1a and the electrode head 1b, and a conducting wire is provided between the main body 1a and the electrode head 1b. Connected.
한편 전극헤드(1b)선단의 탄성전극수단(4)으로서 도전성이 높은 탄성재질로 된 전극선(4a)이 예를 들어 나선형등으로 성형되어 부착된다.On the other hand, as the elastic electrode means 4 at the tip of the electrode head 1b, an electrode wire 4a made of a highly conductive elastic material is molded and attached to, for example, a spiral.
이 전극선(4a)은 바람직하기로는 동선이나 동합금선으로 형성된다. 한편 하부전극(2)의 상면에도 탄성전극수단(4)으로도 상술한 구성의 전극선(4a')이 부착된다. 이 실시예에 있어서는 상하부전극(1, 2)모두가 유사한 곡률의 용접률에 대해 범용으로 사용될수 있으므로 전술할 효과가 더욱 증진될뿐 아니라 용접장치의 소요대수도 더욱 감소될수 있다.This electrode line 4a is preferably formed of copper wire or copper alloy wire. On the other hand, the electrode line 4a 'having the above-described configuration is also attached to the upper surface of the lower electrode 2 as the elastic electrode means 4 as well. In this embodiment, since both the upper and lower electrodes 1 and 2 can be used universally for the welding rate of similar curvature, not only the above-mentioned effect is further enhanced but also the required number of welding apparatuses can be further reduced.
이와 같은 본 고안 용접장치는 곡면용접 뿐 아니라 평면 용접에도 더욱 우수한 효과를 발휘할수 있을 뿐아니라, 셀 구조를 가진 각종 구조들의 용접에 널리 사용될수 있다.The present invention welding apparatus can not only exert more excellent effect in flat welding as well as curved welding, but also can be widely used for welding various structures having a cell structure.
