본 고안은 전자렌지의 도어프레임 절곡구조에 관한 것으로, 보다 상세하게는 전자렌지용 도어를 구성하는 도어프레임의 내측가장자리에 일체로 절곡 형성되어 고주파차단재(Microwave Absorber) 등을 끼우도록 된 협지편을 보다 쉽게 구부릴 수 있도록 한 전자렌지의 도어프레임 절곡구조에 관한 것이다.The present invention relates to a door frame bending structure of a microwave oven, and more particularly, a narrow piece that is formed integrally bent at an inner edge of the door frame constituting the microwave door to sandwich a microwave absorber or the like. It relates to a door frame bending structure of a microwave oven to bend more easily.
일반적으로, 전자렌지의 도어프레임(10)내측 가장자리에는 제1도에 도시된 바와 같이 소정 위치마다 다수개의 협지편(12)을 일체로 절곡형성하여 고주파차단재의 같은 전자렌지용 도어를 구성하는 부품들을 끼워결합할수 있도록 되어있다.In general, the parts forming the same microwave door of the high frequency blocking material by integrally bending a plurality of sandwich pieces 12 at predetermined positions on the inner edge of the door frame 10 of the microwave oven as shown in FIG. It is possible to fit them together.
이와 같은 협지편(12)은 도어프레임(10)의 가장자리로부터 돌설된 일정길이와 폭을 갖는 플레이트를 동일한 방향으로 2~3차례 절곡하여 끼워지는 부품이 쉽게 이탈되지 않도록 하고 있는바, 이 같은 협지편(12)의 절곡공정은 제2도에 도시된 바와 같이, 도어프레임(10)상으로부터 돌설된 플레이트의 소정위치를 일차로 절곡한 다음, 절곡된 부분을 2~3차례 재차 절곡하여 걸림홈이 형성되게 하는 바, 이 같은 종래의 절곡공정에서는 협지편(12)를 소정의 형태로 절곡 형성하기 위하여 슬라이드캠(Slide Cam)과 같은 별도의 지그(14)를 이용하여야 함에 따라 그 절곡작업이 매우 까다롭고 작업공수가 많아져 생산성이 저하된다는 문제점이 있었다.The sandwiching piece 12 is formed by bending a plate having a predetermined length and width protruding from the edge of the door frame 10 two or three times in the same direction so that the fitting component is not easily separated. In the bending process of the piece 12, as shown in FIG. 2, the predetermined position of the plate protruding from the door frame 10 is firstly bent, and then the bent portion is bent again two or three times to engage the groove. In this conventional bending process, the bending work is performed by using a separate jig 14 such as a slide cam in order to bend the clamping piece 12 into a predetermined shape. There is a problem that the productivity is lowered due to the very demanding and laborious work.
본 고안은 이와 같은 종래의 문제점을 해결하기 위한 것으로, 전자렌지용 도어를 구성하는 도어프레임내측 가장자리의 협지편을 절곡함에 있어서 협지편 형성에 필요한 절곡부위에 일정길이의 절개공을 형성함으로써 별도의 지그없이도 손쉽게 절곡할 수 있도록 한 새로운 형태의 전자렌지의 도어프레임 절곡구조를 제공하고자 하는데 목적이 있다.The present invention is to solve such a conventional problem, by forming a cut hole of a certain length in the bending portion required to form the nip pin when bending the nip pin of the inner edge of the door frame constituting the microwave oven door The purpose is to provide a new type of door frame bending structure of a microwave oven that can be easily bent without a jig.
이하, 첨부된 도면에 의하여 본 고안을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
본 고안은 제3도에 도시된 바와 같이 전자렌지용 도어를 구성하는 도어프레임(30)의 가장자리로부터 돌설되는 협지편(32)의 절곡 위치마다 일정길이의 절개공(34)을 형성하여 된 특징을 갖는다.The present invention is characterized by forming a cut hole 34 of a predetermined length for each bending position of the gripping piece 32 protruding from the edge of the door frame 30 constituting the microwave door as shown in FIG. Has
이와 같은 본 고안에서 상기 절개공(34)은 협지편(32)의 폭 방향으로 형성한다.In this invention, the cutting hole 34 is formed in the width direction of the sandwich piece 32.
이같은 본 고안의 작용은 다음과 같다.The operation of the present invention is as follows.
도어프레임(30) 내측가장자리로부터 돌설된 협지편(32)을 절곡형성하고자 하는 경우에 작업자가 별도의 도구를 이용하지 않고, 협지편(32)상의 절곡부에 형성된 절개공(34)을 중심으로하여 그 좌우 양쪽을 잡은 상태에서 절곡시키고자 하는 방향으로 힘을 가하면 쉽게 구부려지면서 원하는 형태로 절곡된다.When the operator wants to bend the gripping piece 32 protruding from the inner edge of the door frame 30, the operator does not use a separate tool, and focuses on the cutting hole 34 formed in the bent portion on the gripping piece 32. If you apply the force in the direction to bend while holding the left and right sides, it is easily bent and bent into a desired shape.
이같은 본 고안을 적용하면 별도의 지그없이도 손쉽게 절곡이 이루어지므로 협지편을 형성하기 위한 시간이 단축되어 생산성이 현저히 증대된다는 효과가 있으며, 별도의 지그가 필요없으므로 생산비를 절감할 수 있다는 경제적인 효과도 있다.When the present invention is applied, the bending is easily performed without a separate jig, which shortens the time for forming a narrow piece, thereby significantly increasing productivity, and the economic effect of reducing the production cost because a separate jig is not required. have.
