Abstract

본 발명은 소재를 소성가공하여 암나사를 만드는 나사전조탭에 대한 것으로, 더욱 상세하게는 외면을 따라 나사산이 형성되고, 곡선형으로 테이퍼진 챔퍼부와 상기 챔퍼부에서 연장되는 평행부를 가진 나사산부를 포함하는 나사전조탭에 있어서, 상기 나사산부는 상기 나사산상에 나사산을 따라 소정의 간격을 두고 돌출되며, 소재의 관통홀 표면을 가압하여 소재를 소성가공하여 소재에 암나사산을 형성하는 복수 개의 돌출부를 추가로 포함하며, 상기 챔퍼부의 돌출부는 상기 평행부에 가깝게 위치하는 돌출부일수록 작은 소성가공량을 가지도록 하여 상기 챔퍼부의 돌출부 각각에 작용하는 소성저항을 균일하게 하고, 상기 챔퍼부의 산정은 길이방향으로 라운드지게 형성하여 소재의 소성유동저항을 최소화하고 상기 평행부의 산정은 길이방향으로 평평하게 형성하여 완성된 암나사의 탄성복원에 의한 암나사와 나사전조탭 간의 마찰저항을 줄이고 가공유의 공급을 원활하게 하여, 향상된 수명을 가지는 나사전조탭에 대한 것이다.
