Description

다중 롤을 포함하는 롤 스탠드에서의 저 마찰 굽힘 시스템{LOW-FRICTION BENDING SYSTEM IN A ROLL STAND COMPRISING SEVERAL ROLLS}LOW-FRICTION BENDING SYSTEM IN A ROLL STAND COMPRISING SEVERAL ROLLS}

본 발명은 입구 측과 출구 측에서 롤 초크(chock)와 스탠드 창(stand window) 사이에 고정되어 제어 수단에 의해 구동될 수 있는 굽힘 블록을 구비한, 다중 롤을 포함하는 롤 스탠드에서의 롤 굽힘 장치에 관한 것이다.The invention relates to a roll bending in a roll stand comprising multiple rolls, having a bending block fixed between the roll chocks and the stand window at the inlet and outlet sides and which can be driven by the control means. Relates to a device.

전제된 유형의 장치는 압연 제품의 평탄도 제어를 위해 작업 롤을 굽히는 액추에이터로서 사용된다. 그 경우. 그러한 액추에이터는 스트립 에지 구역에서의 롤 갭 기하 형상에 직접적으로 영향을 미치는데, 그 때에 작업 롤은 그 위에 놓인 롤의 에지 주위에서 포지티브로 굽혀지고, 압연물의 에지 주위에서 네거티브로 굽혀진다.The device of the predicate type is used as an actuator to bend work rolls for flatness control of rolled products. In that case. Such actuators directly affect the roll gap geometry in the strip edge zone, where the working roll is bent positively around the edge of the roll overlying it and negatively bent around the edge of the roll.

독일 특허 제22 50 953호로부터, 작업 롤 및 지지 롤과 롤 굽힘 장치를 구비하되, 작업 롤의 초크가 스탠드 창에 앵커 고정된 블록 사이에서 안내되고, 작업 롤 빔 교정을 위한 구동을 위해 블록에 배속된 양쪽에서 구동 가능한 피스톤/실린더 유닛에 의해 결합되는 롤 스탠드가 공지되어 있는데, 그러한 롤 스탠드에서는 각각의 블록에서 하부 및 상부 가이드 편이 수직으로 이동될 수 있게 안내되는 반면에, 하나의 가이드 편은 실린더를 수납하고, 다른 하나의 가이드 편은 스탠드 간의 롤 교체를 위해 롤과 평행하게 연장되는 수평 가이드에 의해 수직 방향으로 포지티브 로킹(positive locking) 방식으로 초크와 결합된다.From German Patent No. 22 50 953, a work roll and a support roll and a roll bending device are provided, the choke of the work roll being guided between the blocks anchored to the stand window and mounted on the block for driving for work roll beam calibration. Roll stands are known which are coupled by a piston / cylinder unit which can be driven on both doubled speeds, in which the lower and upper guide pieces are guided vertically in each block while one guide piece is guided. The cylinder is housed and the other guide piece is engaged with the choke in a positive locking manner in the vertical direction by a horizontal guide extending parallel to the roll for roll replacement between the stands.

그러한 장치는 실제로 그 효능이 입증되어 있다. 그러나, 실린더가 구동 측과 종동 측은 물론 입구 측과 출구 측에 배치되어야 한다는 단점이 있다. 그러한 각각의 측의 이동식 지지 장치로 인해, 불가피하게도 높은 마찰력이 발생되고, 아울러 그것은 평탄도 제어에도 악영향을 미치게 된다.Such devices have proven their effectiveness in practice. However, there is a disadvantage that the cylinder must be disposed on the inlet side and the outlet side as well as the driving side and the driven side. Due to each of the movable support devices on each side, inevitably high frictional forces are generated, which in turn adversely affects flatness control.

첨부 도면에는 본 발명의 일 실시예가 도시되어 있는 바, 이하 그 실시예에 의거하여 본 발명을 더욱 상세하게 설명하기로 한다. 첨부 도면 중에서,An embodiment of the present invention is shown in the accompanying drawings, and the present invention will be described in more detail below based on the embodiment. Among the accompanying drawings,

도 1은 구동 측으로부터 바라본 4단 롤 스탠드의 측면도이고,1 is a side view of a four-stage roll stand viewed from the driving side,

도 2는 도 1의 롤 스탠드의 작업 롤 평면에서의 평면도이다.FIG. 2 is a plan view in the working roll plane of the roll stand of FIG. 1. FIG.

본 발명의 목적은 전제된 유형의 시스템에서 마찰력을 감소시키는 것이다.It is an object of the present invention to reduce the frictional force in a presumed type of system.

그러한 목적은 하나의 롤 스탠드의 굽힘 블록에 피스톤/실린더가 배속되고, 그와 대향된 롤 스탠드의 굽힘 블록에 수직 위치 설정 장치가 배속되도록 함으로써 달성되게 된다.Such an object is achieved by having the piston / cylinder assigned to the bending block of one roll stand and the vertical positioning device assigned to the bending block of the roll stand opposite thereto.

수직 위치 설정 장치, 바람직하게는 스핀들 리프팅 기어 유닛에 의해 굽힘 블록을 위치 설정하고 로킹함으로써, 초크가 그를 중심으로 하여 선회될 수 있는 회전점이 생길 수 있게 된다. 즉, 구동 측 및 종동 측의 굽힘력을 굽힘 블록에 도입하는데 단지 1개씩의 실린더만 필요하게 된다.By positioning and locking the bending block by means of a vertical positioning device, preferably a spindle lifting gear unit, a turning point can be created in which the choke can be pivoted about it. That is, only one cylinder is needed to introduce the bending forces on the drive side and the driven side to the bending block.

롤 스탠드에서 굽힘력을 굽힘 블록에 도입하는데 고작 2개의 실린더만이 사용됨으로써, 마찰력이 현저하게 감소될 수 있게 된다.Only two cylinders are used to introduce the bending force into the bending block in the roll stand, so that the frictional force can be significantly reduced.

스핀들 리프팅 기어 유닛에 의해, 롤의 마모 구역도 역시 보상될 수 있게 된다.By means of the spindle lifting gear unit, the wear zone of the roll can also be compensated.
