본 고안은 판재를 원통으로 접합 벤딩할수 있도록한 접합 벤딩(Bending) 금형에 관한것으로서 특히 일회작업으로 원통형 벤딩과, 이음매를 접합하면서 최종치수내기 작업까지 완료하여 진원도를 충족시킬수 있는 접합 벤딩 금형에 관한 것이다.The present invention relates to a joining bending mold that allows joining and bending of a plate by a cylinder. Particularly, a joining bending mold capable of satisfying a roundness by completing a cylindrical bending and a final dimensioning operation while joining a seam in a single operation. will be.
종래에는 판재를 브랭킹(Blanking)한후, 1차웨이브형 또는 타형태로 예비 벤딩하였다,그리고 판재를 이음매부분이 결합가능한 형태로 2차 벤딩한후 이음매를 결합한다,Conventionally, after sheeting (Blanking), pre-bending the primary wave form or other form, and after bending the plate in a form that can be joined to the joint portion, the joint is joined,
상기와 같이 이음매의 결합이 완료되며, 아이보를 벤딩된 판재 내경부에 삽입한후 최종치수내기 작업을 한다.As described above, the coupling of the seam is completed, and the final dimensioning operation is performed after inserting the aibo into the inner diameter of the bent plate.
상기와 같은 판재의 벤딩결합은 여러공정을 거쳐서 제품이 완성되므로 다수의 금형을 필요로 하게되는 것과 재료의 스프링백(Spring Back) 계산이 정확하지 않아 실험작업을 필요로 하는 문제점등이 야기되었다,As the bending of the plate is completed through a number of processes, the product is completed, which requires a large number of molds, and the spring back calculation of the material is not accurate.
본 고안은 상기한 종래의 제문제점등을 해결하기 위하여 안출된 것으로서, 본고안의 주된 목적으론 아이보를 이용한 벤딩 금형에서, 상형을 두개의 편으로 분할하되 편끼리의 위치차를 부여하여 작업진행과정에서 이음매를 결합하면서 판재의 벤딩을 일회공정에서 최종적인 제품까지 가동되도록한 것이 그 특징이다,The present invention was devised to solve the above-mentioned problems, and the main purpose of this paper is to divide the upper mold into two pieces in the bending mold using Aibo, but to give the position difference between the pieces in the process of working The feature is that the bending of the plate is operated from the one-step process to the final product while joining the joints.
상기의 목적을 달성할 수 있는 본고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings that can achieve the above object as follows.
제 1 도 내지 제 3 도에서와 같이, 벤딩 금형에 있어서, 상면 중앙 반원형요홈(2)을 갖고 양측에 45°경사면(3)을 갖는 벤딩다이(1)를 형성한다.As shown in Figs. 1 to 3, in a bending die, a bending die 1 is formed having an upper surface center semicircular groove 2 and a 45 ° inclined surface 3 on both sides.
그리고 상기 벤딩다이(1)와 치합되는, 상형은 하면 중앙에 반원형요홈(6)을 갖고 양측 내면에는 상기 45°경사면(3)과 치합될 수 있는 45°경사면(3')을 갖는 벤딩고정펀치(4)와, 벤딩가동펀치(5)를 슬라이딩되는 상태로 치합고정한다.And the upper die, which is engaged with the bending die 1, has a semi-circular groove 6 at the center of the lower surface and a bending fixed punch having a 45 ° inclined surface 3 'that can be engaged with the 45 ° inclined surface 3 on both inner surfaces. (4) and the bending movable punch 5 are engaged and fixed in a sliding state.
이때, 상기 벤딩가동펀치(5)의 상측에는 스프링(7)을 설치하여서 완충작용을 할 수 있도록 된것이다.At this time, by installing a spring (7) on the upper side of the bending movable punch (5) is to be able to perform a buffering action.
그리고 상기 벤딩다이(1)와 상형 사이에는 아이보현수봉(9)에 의해 설치된 아이보(8)를 설치하여 구성된 것이다.And between the bending die (1) and the upper die is configured by installing the ivory (8) installed by the ivory string rod (9).
미설명부호 10은 판재이다.Reference numeral 10 is a board.
이와 같이 구성된 본고안은 벤딩다이(1) 상면의 반원형 요홈(2)에 제 4 도에서 같이 판재(10)를 올려놓고, 프레스의 램을 하강시키며 아이보현수봉(9)에 의해 설치된 아이보(8)의 힘에 의해 벤딩다이(1)의 반원형요홈(2)에 제 4 도와 같이 U자형 벤딩된다.In this configuration, the present invention places the plate 10 as shown in FIG. 4 on the semicircular groove 2 of the upper surface of the bending die 1, lowers the ram of the press, and is installed by the ivory suspending rod 9. U-shaped bend is performed in the semicircular groove 2 of the bending die 1 by the force of).
그리고 상기 프레스의 램이 계속 하강함에 따라 판재(10)를 상형 일측의 벤딩가동펀치(5)가 가이드되어 펀칭으로 인해 벤딩하여 스프링(7)의 스프링력에 의해 제 5 도에서와 같이 눌러진 상태로 한후, 프레스 램이 계속 하강하면 벤딩 고정펀치(4)가 벤딩가동펀치(5)에서 가이드되면서 벤딩다이(1)의 45°경사면(3)과 상형의 45°경사면(3')이 밀착되면서 눌러 제 6 도에서와 같이 판재(10) 타측을 눌러 판재(10)를 일체형의 형상이 되면서 자연히 결합작업이 이루어 진다.As the ram of the press continues to descend, the bending movable punch 5 on the upper side of the plate 10 is guided and bent due to the punching to be pressed as shown in FIG. 5 by the spring force of the spring 7. When the press ram continues to descend, the bending fixed punch 4 is guided by the bending movable punch 5 while the 45 ° inclined surface 3 of the bending die 1 and the 45 ° inclined surface 3 'of the upper die are in close contact with each other. By pressing the other side of the plate 10 as shown in Figure 6, the plate 10 is formed in one-piece shape, the coupling operation is made naturally.
그리고 램이 하사점에 이르면 금형은 완전한 원형이 되면서 최종 치수내기까지 완료되는 것이다.When the ram reaches the bottom dead center, the mold is fully rounded up to the final dimension.
이상 설명한 바와 같이 판재를 벤딩다이에서 일회작업으로 원통형 벤딩과 이음매를 접합하면서 최종치수내기 작업까지 완료하여 진원도를 충족시키므로서 작업능률 향상은 물론, 벤딩코스트를 현저하게 저감시킬수 있는 매우 유용한 고안이다.As described above, it is a very useful design that can improve the work efficiency as well as significantly reduce the bending cost by completing the final dimensioning work while joining the cylindrical bending and the seam in one bending work in the bending die.
