Abstract

본 발명은 볼트 제작시에 와셔가 볼트 외측으로 빠지지 않도록 볼트에 와셔를 미리 장착시킨 와셔장착 볼트 및 그 제조방법에 관한 것이다.The present invention relates to a washer mounting bolt and a method for manufacturing the washer in which the washer is mounted in advance so that the washer does not fall out of the bolt when the bolt is manufactured.

본 발명의 와셔 장착 볼트는 볼트 헤드(2)와, 이 볼트 헤드와 일체로 된 생크부(5)로 구성되고, 생크부(5)가 볼트 헤드(2) 쪽의 소직경의 비나사산부(3)과 대직경의 나사산부(4)로 구성되고, 소직경의 비나사산부(3)에 이 비나사산부(3)의 직경보다는 크거나 같고 나사산부(4)의 직경보다는 작거나 같은 내경의 와셔(6,6a)가 장착되어 있다. 이에 따라, 볼트에 와셔가 일체로 됨으로써 와셔를 별도로 보관 및 운반하는 작업과 볼트에 와셔를 끼우는 작업 및 인건비를 줄일 수 있을 뿐만 아니라 자동차 라인에 사용하기에 적합하다.The washer mounting bolt of this invention consists of a bolt head 2 and the shank part 5 integrated with this bolt head, and the shank part 5 is a non-threaded part of the small diameter of the bolt head 2 side ( 3) and a large diameter threaded portion 4, the inner diameter of which is larger than or equal to the diameter of the non-threaded portion 3 and smaller than or equal to the diameter of the threaded portion 4 to the small diameter non-threaded portion 3; Washer (6, 6a) is attached. As a result, the washer is integrally formed on the bolt to reduce the work and labor costs of storing and transporting the washer separately and to fit the washer on the bolt, as well as to be suitable for use in an automobile line.

본 발명의 와션 장착 볼트 제조방법은 소정 직경의 긴 볼트 소재를 환봉 형태의 볼트 소재로 절단하는 단계와, 절단된 볼트 소재의 볼트 헤드를 형성시키는 단계와, 이 블토 소재의 생크부에 나사산을 가공하는 단계로 이루어지며, 상기 나사산 가공 단계전에 볼트 소재의 생크부에 와셔를 삽입시키는 단계를 포함하고, 상기 나사산 가공 단계가 롤링에 의해 이루어진다. 이는 와셔 장착 볼트의 대량 생산에 적합하다.The method for manufacturing a washer mounting bolt of the present invention includes the steps of cutting a long bolt material having a predetermined diameter into a round rod-shaped bolt material, forming a bolt head of the cut bolt material, and processing a thread on the shank portion of the bleto material. And a step of inserting a washer in the shank portion of the bolt material before the thread processing step, wherein the thread processing step is performed by rolling. This is suitable for mass production of washer mounting bolts.
