본 고안은 냉장고 문짝커버의 모서리 접합구조에 관한 것으로,The present invention relates to a corner junction structure of the refrigerator door cover,
특히 모서리 접합부에 절곡부를 형성함과 동시에 엠보싱돌기를 형성하고 엠보싱돌기를 이용하여 스폿용접이 가능하도록 한 냉장고 문짝커버의 모서리 접합구조에 관한 것이다.In particular, the present invention relates to a corner joint structure of a refrigerator door cover that forms a bent portion at the same time as the corner joint and forms an embossing protrusion and enables spot welding using the embossing protrusion.
종래에는 냉장고 문짝커버의 모서리를 접합하기 위해서는 첨부도면 제2도에 도시된 바와같이 문짝커버(1)의 4측면에 형성된 측면부(2)를 절곡한 다음 상기 측면부(2)양끝단에 형성된 모서리 접합부(2a)에 용접을 하면되는 것으로, 이때 용접은 아르곤용접을 하게 되는데 이는 모재가 되는 커버모서리 부분이 선 용접의 형태로 이루어지게 되며 커버의 두께가을경우 용접이 어려울뿐만 아니라 용접후 불필요하게 발생되는 슬래그나 용접돌출부를 연마기로써 모서리 표면을 연마하여 처리하여야만 하는 등의 작업능률이 떨어졌으며 용접시 열변형으로 인해 외관이 미려하지 않는등의 많은 문제점이 발생하였던 것이다.Conventionally, in order to bond the edges of the refrigerator door cover, the side joints 2 formed on the four sides of the door cover 1 are bent as shown in FIG. 2 and then the corner joints formed at both ends of the side parts 2. When welding to (2a), the welding is performed argon welding, which is the cover edge portion of the base material is made in the form of line welding and the thickness of the cover In this case, not only the welding is difficult but also the work efficiency such as the need to polish the edge surface by grinding the slag or the welding protrusion that is unnecessary after welding. This occurred.
따라서 본 고안은 상기한 바와같은 종래의 문제점을 해결하고자 안출한 것으로,Therefore, the present invention has been made to solve the conventional problems as described above,
냉장고 문짝커버의 모서리 접합부에 절곡부를 형성함과 동시에 엠보싱돌기를 형성하고 상기 엠보싱돌기를 이용하여 스폿용접이 가능하도록 함으로써 용접부분의 모서리 표면에 돌출이 생기지 않도록 하고 용접시 열변형이 없게하여 외관이 미려할 뿐만 아니라 작업이 간단하면서도 문짝커버의 두께에 제한을 받지않는등 용접작업을 보다 용이하게 할 수 있는 냉장고 문짝커버의 모서리접합구조를 제공함에 그 목적이 있는 것이다.By forming a bent portion at the corner junction of the refrigerator door cover and forming an embossing projection and enabling spot welding using the embossing projection to prevent protrusions on the edge surface of the welded portion and to prevent thermal deformation during welding, the appearance is improved. The purpose is to provide an edge joint structure of the refrigerator door cover that is not only beautiful but also simple and not limited by the thickness of the door cover.
상기한 목적을 달성하기 위한 본 고안을 첨부도면 제3도 내지 제4도에 의거 상세히 설명하면 다음과 같다.Referring to the present invention in detail based on the accompanying drawings 3 to 4 to achieve the above object is as follows.
냉장고 (100)의 문짝커버(10)를 구성함에 있어서,In configuring the door cover 10 of the refrigerator 100,
상기 문짝커버(10)의 4측면에 형성된 측면부(20)의 모서리접합부(20a) 일측끝단에 엠보싱돌기 (20c)가 구비된 절곡부(20b)를 형성하고, 상기 엠보싱돌기(20c)를 이용하여 스폿용접이 가능하도록 구성하였다.The bent portion 20b having an embossing protrusion 20c is formed at one end of the corner joint portion 20a of the side portion 20 formed on the four side surfaces of the door cover 10, and using the embossing protrusion 20c. It was configured to enable spot welding.
미설명부호 30은 스폿용접기의 가압전극이다.Reference numeral 30 denotes a pressure electrode of the spot welder.
이와같이 된 본 고안은 먼저 냉장고 문짝커버(10)의 4측면에 형성된 측면부(20)의 모서리접합부(20a) 일측끝단을 절곡하여 절곡부(20b)를 형성함과 동시에 상기 절곡부(20b)에 엠보싱돌기(20c)를 형성하고 상기 문짝커버(10)의 4측면에 형성된 측면부(20)를 90°각도로 절곡하여 각 측면부(20)의 모서리 접합부(20a)가 일치되도록 한 다음 용접을 하면 되는 것으로, 이때 상기 모서리 접합부(20a) 일측끝단에 형성된 절곡부(20b)에 구비된 엠보싱돌기(20c)를 이와 대응되는 타측 모서리 접합부(20a)와 밀착되도록 한 다음 제5도에 도시된 바와 같이 스폿용접기로 스폿용접을 하면 상기 엠보싱돌기(20c)가 접합부(20a)와 서로 점용접되어 스폿용접이 가능하게 된다.The present invention as described above first bends one end of the corner joint portion 20a of the side portion 20 formed on the four sides of the refrigerator door cover 10 to form the bent portion 20b and at the same time emboss the bent portion 20b. Forming the projection 20c and bending the side portion 20 formed on the four sides of the door cover 10 at an angle of 90 ° to ensure that the corner joints 20a of each side portion 20 coincide and then weld At this time, the embossed protrusion 20c provided at the bent portion 20b formed at one end of the edge junction 20a is brought into close contact with the other corner junction 20a corresponding thereto, and then the spot welder as shown in FIG. When the furnace is spot welded, the embossing protrusions 20c are spot welded with the joint portion 20a to allow spot welding.
일반적으로 스폿용접은 두용접재를 서로 겹쳐서 순간적으로 고전류를 흘려서 부분융착하는 것으로, 이는 점용접을 요구하므로써 모서리부분등 접합부가 평판일때는 불가능하였으나 본 고안에서는 접합부에 엠보싱돌기를 형성하여서 이를 극복하였다.In general, spot welding overlaps two welding materials with each other, and instantaneously flows a high current to partially fusion, which is impossible when the joints such as edges are flat by requiring spot welding, but in the present invention, an embossing protrusion was formed in the joint to overcome this problem. .
상기와 같이 본 고안은 냉장고 문짝커버의 모서리 접합부에 엠보싱돌기가 구비된 절곡부를 형성하고 상기 엠보싱돌기를 이용하여 스폿용접이 가능하도록 함으로써 용접부분이 모서리 표면에 돌출하지 않도록 하고 용접시 열변형이 없어 외관이 미려할 뿐만 아니라 작업이 간단하고 문짝커버의 두께에 제한을 받지않고 용접을 할 수 있는등의 매우 유용하고 실용적인 고안인 것이다.As described above, the present invention forms a bent portion having an embossing protrusion at the corner junction of the refrigerator door cover and enables spot welding using the embossing protrusion so that the welded portion does not protrude on the corner surface and there is no heat deformation during welding. It is a very useful and practical design such as not only beautiful appearance but also simple operation and welding without being limited by the thickness of the door cover.
