Abstract | The present invention relates to a honing tool for a seamless pipe which surface-treats a seamless pipe drilled by piercing while progressing forward by a plug coupled to a mandrill before rolling the seamless pipe into a desired size. To this end, the honing tool for a seamless pipe comprises: a head part entering a drilled hole of a seamless pipe; a machining part extended on the other side of the head part to have a larger diameter than the head part, and removing fine cracks with a drilling bead created on a drilled surface of the seamless pipe; and a surface-treating part extended on the other side of the machining part to surface-treat the remaining cracks while compacting a machined surface of the seamless pipe.
본 발명은 피어싱 가공에 의해 천공된 심리스 파이프를 소망하는 사이즈로 압연 가공하기에 앞서 맨드릴에 결합된 플러그에 의해 전방으로 진행하면서 심리스 파이프의 천공홀을 표면 처리하는 심리스 파이프용 호닝툴에 관한 것으로, 이를 위해 심리스 파이프의 천공홀에 진입되는 헤드부;와, 상기 헤드부의 타측에 연장되어 상기 헤드부 보다 상대적으로 큰 직경사이즈를 갖고, 상기 심리스 파이프의 천공면에 발생된 천공비드와 함께 미세 크랙을 제거하는 가공부;와, 상기 가공부의 타측에 연장되어 심리스 파이프의 가공면을 다지면서 잔여 크랙을 표면 처리하는 표면처리부;로 이루어지는 것을 특징으로 한다. |
