Claims (3)

로울 스탠드에 지지되고 서로 대향 배치된 두개의 조정된 로울이 축향으로 고정된 원추형 축위에 설치된 관형 가공물위를 왕복운동하며, 회전구동된 로울이 이들 원주표면위의 경사지고 원추형 축의 형상에 적합하고 축위의 가공물을 굴러내보내기 위한 작업행로를 가지고, 로울이 추력을 발생시킬 목적과 회전을 위한 로울 스탠드 주기의 공급사점과 송출사점양자에서 압연재료를 방출시키는 압연법에 있어서, 가공물에 행해진 전압연 작업의 대부분이 로울스탠드의 전진행정상에서 일어나고, 전압연 작업의 일부분이 후진 행정상에서 일어나며, 가공물은 각 공급사점과 송출사점에서 부분적으로 회전됨을 특징으로 하는 관의 압연방법.Two coordinated rolls supported on the roll stand and disposed opposite to each other reciprocate on a tubular workpiece mounted on an axially fixed conical shaft, with the rotationally driven rolls adapted to the shape of the inclined and conical shafts on these circumferential surfaces. A rolling work carried out on a workpiece in a rolling method having a work path for rolling out a workpiece of the roller, in which the roll releases the rolled material from the feed dead point and the discharge dead point of the roll stand cycle for the purpose of generating the thrust and rotation of the roll stand. Most of the rolling takes place in the forward stroke of the roll stand, part of the rolling operation takes place in the reverse stroke, and the workpiece is partially rotated at each supply point and discharge point. 제1항에 있어서, 로울 스탠드의 각 주기에서 가공물의 전회전이 50-70%이고, 각 공급사점과 송출사점에서의 회전범위가 20°-40°임을 특징으로 하는 방법.The method according to claim 1, wherein the total rotation of the workpiece in each cycle of the roll stand is 50-70%, and the rotation range at each feed point and delivery point is 20 ° -40 °. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
