Description

판재로 형성된 체결너트{Nuts created by plate sheet structure}Nuts created by plate sheet structure

본 발명은 판재(板材)성형공법으로 제조된 체결너트의 결합구조에 관한 것으로 판재성형 체결너트의 다각형 플렌지 하부에 연접하여 다양한 결합구조를 성형하여 제품의 품질과 피결합재와의 결합강도를 향상시킬 수 있게 한것이다.The present invention relates to a coupling structure of a fastening nut manufactured by a plate molding method, which is connected to a lower portion of a polygonal flange of a plate forming fastening nut, thereby forming various coupling structures to improve product quality and bonding strength with a binder. I made it possible.

종래의 PDP.LCD 셋톱박스등 전기, 전자제품의 조립에서 사용되는 위치결정형 체결너트는 각형이나 요철형 단면을 가진 소재를 선반에서 절삭 가공하여 지금까지 생산하고 있으며 근래에는 열간단조방법에 의해 제조가 이루어 지고 있다.Positioning fastening nuts used in the assembly of electric and electronic products such as conventional PDP and LCD set-top boxes have been produced by cutting and processing materials with square or uneven cross-section on lathes. It is done.

이렇게 형성되는 위치결정형 체결너트(A)의 구조는 상단 주연부가 만곡부로 형성되고 내둘레 공간부에는 체결너트의 길이방향으로 나사부(B)를 형성하고 플렌지(C)의 연변에 홈부(D)를 형성하는 등 많은 공정을 필요로 했으므로 재료의 비효율적인 사용, 제조시간 및 인력의 과다 소모 등으로 인해 생산비가 많이 소요되었고 열간단조방식에 의한 가공은 복잡한 구조를 용이하게 성형할 수는 있으나 고온에 의한 가공이어서 표면 불량과 작업환경의 악화등의 문제가 발생하였다.The structure of the positioning fastening nut (A) formed in this way is formed in the upper periphery of the curved portion and the inner space around the threaded portion (B) is formed in the longitudinal direction of the fastening nut and the groove (D) on the edge of the flange (C) Since many processes were required, such as forming, the production cost was high due to the inefficient use of materials, excessive production time, and excessive consumption of manpower. The processing by hot forging can easily form complex structures, but After processing, problems such as surface defects and deterioration of the working environment occurred.

본 발명은 상기와 같은 체결너트의 문제점을 해소하기 위해 체결너트를 제작 할때에 판재성형에의한 제조 공법을 사용하며, 결합구조 또한 다양하게 성형함으로써 시간과 인력의 과다 소모를 줄이고 생산비를 절감하면서 경량화 및 균질화된 제품을 양산하며, 체결너트를 피결합재와 결합시에 체결너트를 압입다이에 놓인 피결합재에 삽입한후 압입성형펀치에 의해 강제 압입시키면 다각형 플렌지부가 피결합재에 압입되면서 발생하는 피결합재의 체적증가부분이 고체의 유동에 의해 반원형 요홈이나 걸림돌출부 및 걸림공에 전이 충전되는 복합력으로 체결너트와 피결합재 가 견고하게 결합되어 체결력 및 회전방지력을 발생 시킬수 있게 한것으로 첨부된 도면에 의해 상세히 설명하면 다음과 같다.The present invention uses the manufacturing method by the plate molding when manufacturing the fastening nut to solve the above problems of the fastening nut, by combining a variety of coupling structure also reduces the excessive consumption of time and manpower and reduce the production cost While mass-producing lightweight and homogenized products, when the fastening nut is inserted into the material to be placed in the press-die, when the fastening nut is inserted into the material to be placed in the press-die, the force of the polygon flange is pressed into the material to be inserted. The increase in volume of the material to be bonded is a composite force in which the semi-circular groove, the locking protrusion and the locking hole are transferred by solid flow, so that the fastening nut and the material to be tightly coupled to generate the fastening force and the rotation preventing force. If described in detail as follows.

이와 같이 된 본 발명은 다양한 결합구조로 성형된 체결너트와 피결합재를 상호 결합시에 압입다이에 놓인 체결너트와 피결합재를 압입성형펀치로 리베팅 결합고정 하므로써 높은 체결력이 증대되고 이완됨이 없으며 경량화된 고품질의 제품을 생산가는 절감하면서 다량생산 할 수 있는 효과가 있다.The present invention as described above has a high tightening force is increased and relaxed by riveting and fastening the fastening nut and the binder to be placed in the indentation die when the fastening nut and the member to be bonded to each other are bonded to each other by a press-molding punch. There is an effect that the mass production while reducing the production price of high-quality lightweight products.

판재로 형성된 체결너트에 있어서, 일정두께를 갖는 외측원통부(1)와, 상기 외측원통부(1)의 일측단에 형성되는 다각형 플랜지부(2)와, 상기 외측원통부(1)의 타측단에 일정간격 이격되게 연결되어 평행하게 형성되되 그 내부에 나사부(3)가 형성되어 일정두께를 갖는 내측원통부(4)와, 상기 다각형 플랜지부(2)에 인접한 상기 외측원통부(1) 둘레에 반원형 요부(6)를 형성하거나 박약부(7)를 형성하거나 또는 등간격으로 걸림돌출부(8)(8')와 걸림공(9)(9')을 각각 다수개 형성한다.In a fastening nut formed of a sheet material, an outer cylindrical portion 1 having a predetermined thickness, a polygonal flange portion 2 formed at one end of the outer cylindrical portion 1, and the other of the outer cylindrical portion 1 The inner cylindrical portion 4 has a predetermined thickness and is connected in parallel to be spaced apart at regular intervals and has a threaded portion 3 formed therein, and the outer cylindrical portion 1 adjacent to the polygonal flange portion 2. Semicircular recesses 6 are formed on the periphery, thin portions 7 are formed, or a plurality of locking projections 8, 8 'and locking holes 9, 9' are formed at equal intervals, respectively.
