Abstract

The columns provide guidance for the roller insert (2) and accommodate flexure blocks. A short-stroke adjustment cylinder (7) is located between the lower roller support insert (8) and the lower traverse (5). By separate arrangement of the tension spindles (3) and the roller insert (2) in the machine frame columns (1), the functions of force transmission onto the rollers and guidance for the roller inserts (2) are separated. An independent claim is included for the corresponding method of adjustment.

Description

本発明は、ロールスタンドおよび圧延時におけるロールスタンドの調整方法に関する。   The present invention relates to a roll stand and a method for adjusting the roll stand during rolling.

ロールスタンドは一般に、制御可能なロール圧下装置と一定したパスラインを達成するための補助圧下装置とを備えた２つのロールハウジングからなる。この構造に起因してハウジングウインドーは圧延力の付加時に狭まる。圧延力が異なる場合、ハウジングウインドー内でロールハウジングとロールチョックとの間に異なる隙間が存在する。   A roll stand generally consists of two roll housings with a controllable roll reduction device and an auxiliary reduction device to achieve a constant pass line. Due to this structure, the housing window is narrowed when a rolling force is applied. When the rolling force is different, there are different gaps between the roll housing and the roll chock in the housing window.

特許文献１により公知のユニバーサルロールスタンドは、垂直ロール用の密閉フレームと水平ロール用チョックとからなり、ロールは上下のクロスビームで支持される。クロスビームは、該クロスビームのフレーム内に挿通され該フレーム内で軸線方向への摺動が規制されかつ回転可能に支承された引張スピンドルによって、該クロスビームが（従って水平ロールが）圧延線またはパスラインに対して中心で圧下可能であるように互いに結合されている。フレームは基礎のソールプレートに直接載置されている。   The universal roll stand known from Patent Document 1 includes a vertical roll sealing frame and a horizontal roll chock, and the roll is supported by upper and lower cross beams. The cross beam is inserted into the frame of the cross beam, and the cross beam (and thus the horizontal roll) is rolled by means of a tension spindle that is axially restricted and rotatably supported in the frame. They are connected to each other so that they can be reduced in the center with respect to the pass line. The frame is placed directly on the base sole plate.

特許文献２により公知のロールスタンドは、４つのハウジングコラムからなり、ハウジングコラムはソールプレートで強固に固定され、かつハウジングコラム内には、軸線方向への摺動が規制されかつ回転可能に支承された引張スピンドルが配置されており、引張スピンドルの上端と下端が逆方向のねじ部を備え、かつ該ねじ部が上下のクロスビームに螺合することで、クロスビームがロールセットを介して互いに逆方向に変位可能である。ハウジングコラムはロールチョック用ガイドとして役立つ。下バックアップロールチョックと下クロスビームとの間に、圧延力を付加するためのショートストローク圧下シリンダが配置されている。   The roll stand known from Patent Document 2 is composed of four housing columns, which are firmly fixed by a sole plate, and are supported in the housing column so that sliding in the axial direction is restricted and rotatable. The tensioning spindle is arranged, and the upper and lower ends of the tensioning spindle are provided with screw parts in opposite directions, and the threaded parts are screwed into the upper and lower cross beams, so that the cross beams are reversed from each other via the roll set. It can be displaced in the direction. The housing column serves as a guide for the roll chock. A short stroke reduction cylinder for applying a rolling force is disposed between the lower backup roll chock and the lower cross beam.

本発明の課題は、別の補助手段なしに一定したパスラインに常に調整される新規なロールスタンドの構造原理を提供することである。   The object of the present invention is to provide a novel roll stand construction principle that is always adjusted to a constant pass line without further auxiliary means.

この課題は本発明によれば以下の特徴の組合せによって解決される。即ち、本発明のロールスタンドは、４つのハウジングコラムを備え、前記ハウジングコラムはそれぞれソールプレートに固定され、前記ハウジングコラム内には、軸線方向への摺動が規制された状態で回転可能に支承された引張スピンドルが配置され、前記引張スピンドルの上端部及び下端部には互いに逆方向のねじ部が設けられ、前記ねじ部に上クロスビームおよび下クロスビームが螺合することで、前記ねじ部を介してロールセットが互いに逆方向に変位可能であり、さらに、前記ハウジングコラムにより、ロールチョックが案内されると共に、ベンディングブロックが保持され、
前記下クロスビームと下バックアップロールチョックとの間に、圧延力を付加するためのショートストローク圧下シリンダ（７）が配置され、前記引張スピンドルと前記ロールチョックとが前記ハウジングコラム内に別々に配置されることにより、ロールへの力の伝達と前記ロールチョックの案内とを独立して行えるように構成されている。 This problem is solved according to the present invention by a combination of the following features. That is, the roll stand of the present invention includes four housing columns, each of which is fixed to a sole plate, and is supported in the housing column so as to be rotatable in a state in which sliding in the axial direction is restricted. The tension spindle is arranged, and the upper end and the lower end of the tension spindle are provided with screw parts in opposite directions, and the upper cross beam and the lower cross beam are screwed into the screw part. The roll sets are displaceable in opposite directions via each other, and the housing column guides the roll chock and holds the bending block,
A short stroke reduction cylinder (7) for applying a rolling force is arranged between the lower cross beam and the lower backup roll chock, and the tension spindle and the roll chock are separately arranged in the housing column. Thus, the transmission of force to the roll and the guidance of the roll chock can be performed independently.

さらにこの課題は、請求項５の特徴を有するロールスタンドを調整するための方法によって解決される。   This problem is further solved by a method for adjusting a roll stand having the features of claim 5.

本発明の諸構成は従属請求項から明らかとなる。   Various configurations of the invention will become apparent from the dependent claims.

本発明は、対向する部材が右ねじ部と左ねじ部とを介して均一に（または不均一に）互いに接近または離反する機構を基本とする。それと共に、圧延力を伝達する機構がロールチョックを案内する機構から分離され、これによりロールハウジング窓部の狭窄等の諸欠点はもはや現れない。また、「うなり」の傾向も本質的に改善される。   The present invention is based on a mechanism in which opposing members approach or separate from each other uniformly (or non-uniformly) via a right-hand thread portion and a left-hand thread portion. At the same time, the mechanism for transmitting the rolling force is separated from the mechanism for guiding the roll chock, so that various disadvantages such as narrowing of the roll housing window no longer appear. In addition, the tendency of “growing” is essentially improved.

本発明の詳細について、以下、図面に基づいて説明する。   Details of the present invention will be described below with reference to the drawings.

この構造体は実質的に４つの溶接されたハウジングコラム１からなり、ハウジングコラムはロールチョック２の案内部材と引張スピンドル３の軸受けとを兼ねる。上下のクロスビーム４、５を介して圧延力を伝達する引張スピンドル３は、クロスビームを相互に接近または離反させる。ハウジングコラム１は基礎、すなわちソールプレート６と鋳固められ、ソールプレート６はアンカーボルトで固定されている。強度設計はロールチョック２によって予想される負荷に応じて行われる。右ねじ部および左ねじ部を有する引張スピンドル３は、未負荷の状態でロールスタンドの所定位置に移動する。次に、ショートストローク圧下シリンダ７を介して圧延力が調整され、圧延状態ではクロスビームを介して引張ロッドに圧延力が導入される。この強度設計は予想される最大圧延力に従って行われる。圧延時のセルフロックは、ねじ部の小さなピッチによって確保されており、付加的に変位駆動装置内のブレーキを介して所定位置を確保することができる。さらに、小さな圧下力用に、ショートストローク圧下シリンダ７とは反対側の上クロスビーム４内に小さな補助圧下シリンダ（図示せず）を組付けておくことができる。   This structure consists essentially of four welded housing columns 1, which double as guide members for the roll chock 2 and bearings for the tension spindle 3. The tension spindle 3 that transmits the rolling force via the upper and lower cross beams 4 and 5 brings the cross beams closer to or away from each other. The housing column 1 is solidified with a foundation, that is, a sole plate 6, and the sole plate 6 is fixed with anchor bolts. The strength design is performed according to the load expected by the roll chock 2. The tension spindle 3 having the right thread portion and the left thread portion moves to a predetermined position of the roll stand in an unloaded state. Next, the rolling force is adjusted via the short stroke reduction cylinder 7, and in the rolling state, the rolling force is introduced to the tension rod via the cross beam. This strength design is performed according to the maximum rolling force expected. Self-locking at the time of rolling is ensured by a small pitch of the threaded portion, and in addition, a predetermined position can be secured via a brake in the displacement drive device. Furthermore, a small auxiliary reduction cylinder (not shown) can be assembled in the upper cross beam 4 on the side opposite to the short stroke reduction cylinder 7 for a small reduction force.

引張スピンドル３は、４つの同期された個別の駆動装置を介して、または駆動伝達機構を備えた１つの駆動装置を介して駆動される。上下のクロスビーム４、５は引張スピンドルの回動方向に応じて互いに接近または離反する。その際、ロール直径（バックアップロール、中間ロール、ワークロール）がそれぞれ同じ場合、ワークロールは常にパスラインに調整される。   The tensioning spindle 3 is driven via four synchronized individual drives or via a single drive with a drive transmission mechanism. The upper and lower cross beams 4, 5 approach or separate from each other depending on the rotation direction of the tension spindle. At that time, if the roll diameters (backup roll, intermediate roll, work roll) are the same, the work roll is always adjusted to the pass line.

構成要素はすべて簡単に加工することのできる完成品である。他の利点は組立のための個別構成要素の重量が小さいことである。   All components are finished products that can be easily processed. Another advantage is the low weight of the individual components for assembly.
