Abstract

A manufacturing method of a clinching nut is provided to drastically improve productivity compared to the existing cutting method and reduce the production cost by manufacturing the clinching nut in a forging method using a metallic mold and to enhance quality of the clinching nut by removing bubbles or impurities in a material and precisely, finely, and strongly forming crystal particles. A clinching nut(10) comprises a screw hole(11) formed inside; an anchor step(15) formed on the outer peripheral surface in a direction to be pressed onto a base metal from a main body unit; and a serration(17) formed between the main body unit and the anchor step. A manufacturing method of the clinching nut comprises the steps for forming a first slope unit(14) to form the anchor step downward a circumferential material(10a,P1); forming an upper inlet port(11a) of the screw hole on the material and simultaneously forming an anchor protrusion step(15a) by pressing the first slope unit(P2); forming a second slope unit(16) and a lower inlet port(11b) of the screw hole at the main body adjacent to the anchor protrusion step(P3); forming the serration by pressing the second slope unit(P4); and broadening the anchor step by pressing the protrusion step(P5).

본 발명은 금형을 이용하는 단조공법으로 클린칭너트를 제조함으로써 절삭가공에 비하여 생산성을 획기적으로 향상시켜 제조원가를 절감시키며 품질특성을 향 상토록 하는 클린칭너트의 제조방법에 관한 것이다.The present invention relates to a manufacturing method of a clinching nut to manufacture a clinching nut by a forging method using a mold to significantly improve productivity compared to cutting, thereby reducing manufacturing cost and improving quality characteristics.

클린칭너트(Clinching-nut)는 나사산을 만들기 어려운 연약한 재질이나 얇은 재질에 박아서 고정하기 위한 인서트로서 모재에 장착되는 일측에는 모재에 압착시키기 위한 앵커단과 세레이션(나사산 모양의 삼각형의 작은 이를 무수히 형성한 것)이 형성되어 구성되는 것이다.Clinching-nut is an insert for fixing to a soft material or thin material that is difficult to make a thread, and on one side mounted on the base material, there is a large number of anchor ends and serrations Formed) is formed.

이러한 구성에 의하여 클린칭너트를 모재에 프레스로 압착하면 모재가 변형되면서 클린칭너트에 결착되어 탈거가 방지됨으로 모재에 너트를 용접설치하는 것과 같은 효과를 얻게 된다.When the clinching nut is pressed into the base material by such a configuration, the base material is deformed and bound to the clinching nut, thus preventing the removal of the clinching nut.

이와 같은 클린칭너트(10)의 구성을 좀더 상세히 살펴보면 도 1 및 도 2에 도시된 바와 같이, 내부에는 나사홀(11)이 형성되고, 외주면은 본체부(13)에서 모재(30)에 압착되는 쪽으로 앵커단(15)이 돌출 형성되며 상기 세레이션(17)은 돌출단(15)과 본체부(13) 사이에 형성되어 있다.Looking at the configuration of such a clinching nut 10 in more detail, as shown in Figures 1 and 2, a screw hole 11 is formed inside, the outer peripheral surface is pressed to the base material 30 in the main body portion 13 An anchor end 15 is formed to protrude toward the side, and the serration 17 is formed between the protruding end 15 and the main body 13.

상기 앵커단은 선단부를 향하여 벌어지도록 형성되어 프레싱에 의하여 상기 앵커단(15)과 세레이션(17) 사이의 홈으로 모재(30)가 변형유입되어 결착이 이루어지는 것이다.The anchor end is formed so as to open toward the front end portion is formed by binding the base material 30 into the groove between the anchor end 15 and the serration 17 by pressing.

그런데, 이와 같은 클린칭너트의 제조가 현재까지 절삭공법에 의존하여 이루어짐으로써 생산성이 미미하여 제조원가가 고가로 되는 문제점이 있었다.However, since the manufacturing of such clinching nuts is made so far depending on the cutting method, there is a problem in that the productivity is insignificant and the manufacturing cost becomes expensive.

즉, 외경 규격이 대개 8㎜ 이하의 작은 크기로 형성되는 클린칭너트를 상술한 바와 같은 형상으로 절삭가공하기 위하여는 정확한 파지 및 취급에 어려움이 있을 뿐만 아니라 특히 선단으로 갈수록 점차 외경이 확장형성되는 앵커단의 절삭가 공에 시간과 인력이 막대하게 낭비되었다.That is, in order to cut and process the clinching nut, which is usually formed with a small size of 8 mm or less in the shape as described above, it is difficult to accurately grasp and handle, and in particular, the outer diameter gradually expands toward the tip. The cutting of the anchor stage wasted a lot of time and manpower in the ball.
