The present invention relates to a device for bending both ends of the iron plate (10) at an obtuse angle, Figure 3 is a view showing a bending device according to the present invention. As shown in the drawing, the bending apparatus for the iron plate 10 for the door has four molds 21, 22, 23, 24 having inclined surfaces inclined at an angle to each other on the outer surface, and a mold 21 positioned on the upper side. (22) (23) (24) It is rotatably installed on the outside of the mold (21) (22) which is required of the roller (30) and four molds (21) (22) (23) (24). (23) and (24) includes proximity means for bringing the roller (30) close.

이를 상세하게 설명하면, 4개의 금형(21)(22)(23)(24)은 동심으로 배치되는데, 이들의 중심에는 그 외측이 분기되어 각각의 금형(21)(22)(23)(24)에 연결된 연결부재(40)가 설치된다. 근접수단은 회전축(51)을 개재하여 연결부재(40)의 중심에 결합설치된 모터(50)를 포함한다. 즉, 모터(50)가 연결부재(40)를 통하여 금형(21)(22)(23)(24)을 회전시켜 롤러(30)에 근접되는 금형(21)(22)(23)(24)을 변경하여 벤딩각도를 조정하게 되는 것이다. 각각의 금형(21)(22)(23)(24)의 외측면에는 서로 다른 각도로 경사진 경사면(20a)이 형성된다.In detail, the four molds 21, 22, 23, and 24 are arranged concentrically, and the centers thereof are branched to their outer sides so that the respective molds 21, 22, 23, and 24 are formed. Is connected to the connecting member 40. Proximity means includes a motor 50 coupled to the center of the connecting member 40 via the rotary shaft 51. In other words, the motor 50 rotates the molds 21, 22, 23, 24 through the connecting member 40, and the molds 21, 22, 23, 24 close to the roller 30. To change the bending angle. The inclined surfaces 20a inclined at different angles are formed on the outer surfaces of the respective molds 21, 22, 23, 24. FIG.

그리고 연결부재(40)의 하방에는 작동축(61)이 승강운동하는 실린더(60)가 설치되고, 작동축(61)의 상단이 연결부재(40)에 결합설치됨으로써 금형(21)(22)(23)(24)을 승강시켜 금형(21)(22)(23)(24)과 롤러(30)사이에서 벤딩된 도아용 철판(10)이 분리될 수 있도록 한다.In addition, a cylinder 60 in which the operating shaft 61 moves up and down is installed below the connecting member 40, and an upper end of the operating shaft 61 is coupled to the connecting member 40 to install the molds 21 and 22. The 23 and 24 are lifted to allow the iron plate 10 bent between the molds 21, 22, 23, 24 and the roller 30 to be separated.

이와 같이 구성된 본 발명에 따른 냉장고의 도아용 철판 벤딩장치의 작동은 다음과 같다.Operation of the iron plate bending apparatus for the door of the refrigerator according to the present invention configured as described above is as follows.

도아용 철판(10)의 단부를 롤러(30)와 금형(21)(22)(23)(24)사이에 위치시키후 실린더(60)를 작동시켜 금형(21)(22)(23)(24)을 롤러(30)에 압착시킨다. 이후 롤러(30)를 금형(21)(22)(23)(24)의 외측면을 따라 회동시키면 도아용 철판(10)의 단부가 금형(21)(22)(23)(24)의 외측면에 형성된 경사면을 따라 벤딩된다.The end of the iron plate 10 for the door is positioned between the roller 30 and the molds 21, 22, 23 and 24, and then the cylinder 60 is operated to mold the molds 21, 22 and 23 ( 24) is pressed on the roller (30). Then, when the roller 30 is rotated along the outer surface of the molds 21, 22, 23, 24, the end of the iron plate 10 for the door is outside the molds 21, 22, 23, 24. It is bent along the inclined surface formed on the side.

한편 벤딩각을 변경하기 위해서는 모터(50)를 회전시키면 금형(21)(22)(23)(24)을 90° 회전시키거나 180° 혹은 270°회전시켜면 다른 경사각을 갖는 금형(21)(22)(23)(24)이 롤러(30)에 근접되게 되는 것이다.On the other hand, in order to change the bending angle, when the motor 50 is rotated, the molds 21, 22, 23, and 24 are rotated 90 degrees or 180 degrees or 270 degrees, and the molds 21 having different inclination angles ( 22 and 23 and 24 are brought close to the roller 30.

이상에서 상세하게 설명한 바와 같이, 본 발명에 따른 냉장고의 도아용 철판 벤딩장치는 모터를 이용하여 금형을 회전시킴으로써 도아용 철판의 벤딩각을 쉽고 편리하게 변경할 수 있는 이점이 있다.As described in detail above, the iron sheet bending apparatus for a refrigerator according to the present invention has an advantage of easily and conveniently changing the bending angle of the iron sheet for a door by rotating a mold using a motor.
