Description
本発明は、入口側および出口側で、ロールチョックとロールスタンド窓との間に固定され、調節手段によって負荷可能な撓みブロック(Biegebloecken)を有する、多重式ロールスタンド内においてロールを撓ませるための装置に関する。 The invention relates to an apparatus for deflecting a roll in a multiple roll stand, having a flex block (Biegebloecken) fixed between the roll chock and the roll stand window on the inlet side and the outlet side and loadable by adjusting means About.
冒頭に記載した様式の装置は、圧延製品を平坦度制御するために、ワークロールを撓ませるための調節部材として使用される。
この調節部材は、この場合、ストリップ縁部領域内における圧延ロール間隙幾何学的形状に対しての直接的な影響を有し、その際、これらワークロールが、正の向きにその上方に存在するロールのこれら縁部の周りを湾曲され、且つ、負の向きに圧延材のこれら縁部の周りを湾曲される。
An apparatus of the type described at the beginning is used as an adjusting member for deflecting the work roll in order to control the flatness of the rolled product.
This adjusting member in this case has a direct influence on the mill roll gap geometry in the strip edge region, with these work rolls lying above it in a positive orientation. Curved around these edges of the roll and curved around these edges of the rolled material in a negative orientation.
ドイツ連邦共和国特許第22 50 953号明細書(特許文献1)から、ワークロールおよびバックアップロール、並びに圧延ロール撓み装置を有する、ロールスタンドであって、
このロールスタンド内において、これらワークロールのチョックが、ロールスタンド窓内において引っ掛け固定されたブロックの間に案内されており、且つ、これらワークロールのロール胴キャンバ補正のための負荷のために両側で負荷可能なこれらブロックに所属して設けられたピストンシリンダーユニットによって結合されている様式の、上記ロールスタンドが公知であり、その際、
それぞれのブロックに、下側、および上側の案内部片が垂直方向に、摺動可能に案内されており、それに対して、一方の案内部片が、シリンダーを収容し、および他方の案内部片がピストンと結合されており、且つ、これら案内部片が、チョックと、水平方向案内部を介して、垂直方向で形状一体的に結合されており、これら水平方向案内部が、ロール交換のために、これらスタンドの間で、これらロールに対して平行に延長されている。このようにして、圧延ロールを撓ませるために、それぞれの側で、2つのピストンシリンダーユニットを必要とすることは達せられるべきである。
Within this roll stand, the chocks of these work rolls are guided between blocks that are hooked and fixed in the roll stand window, and on both sides due to the load for correcting the roll cylinder camber of these work rolls. Such a roll stand is known in the form of being connected by a piston-cylinder unit provided belonging to these loadable blocks,
In each block, the lower and upper guide pieces are slidably guided in the vertical direction, whereas one guide piece accommodates the cylinder and the other guide piece. Are coupled to the piston, and these guide pieces are integrally coupled in the vertical direction with the chock and the horizontal guide, and these horizontal guides are used for roll replacement. Furthermore, between these stands, it is extended in parallel with these rolls. In this way, it should be reached that two piston cylinder units are required on each side in order to deflect the rolling roll.
この装置は、実際上は、有用であることが実証された。しかしながら、このシリンダーが、作動側および操作側、並びに、入口側および出口側に設けられねばならないことは欠点である。この移動可能な、それぞれの側の軸受部によって、不可避に高い摩擦力が発生し、これら摩擦力は、それに加えて、不利に、平坦度制御に対して影響を及ぼす。 This device has proven useful in practice. However, it is a disadvantage that this cylinder must be provided on the working and operating sides, as well as on the inlet and outlet sides. This movable bearing on each side inevitably generates high frictional forces, which in turn adversely affect the flatness control.
従って、本発明の根底をなす課題は、冒頭に記載した様式のシステム内における摩擦力を低減することである。 The problem underlying the present invention is therefore to reduce the friction forces in the system of the type described at the outset.
この課題を解決するために、一方の圧延ロールスタンドの撓みブロックに、ピストンシリンダーが、および、相対して位置している圧延ロールスタンドの撓みブロックに、垂直方向位置決め装置が、所属して設けられていることが提案される。 In order to solve this problem, a vertical cylinder is attached to the bending block of one rolling roll stand and the piston cylinder and the bending block of the rolling roll stand located opposite to each other. It is proposed that
垂直方向位置決め装置、有利にはスピンドル往復動伝動装置を用いての、これら撓みブロックの位置決め、および固定によって、その回転点を中心にしてチョックが旋回される、回転点が形成され得る。これら撓みブロック内へと作動側および操作側の撓み力を導入するために、従って、ただそれぞれ1つのシリンダーだけが必要である。 By positioning and fixing these flexure blocks using a vertical positioning device, preferably a spindle reciprocating transmission device, a turning point can be formed in which the chock is pivoted about its turning point. In order to introduce the actuating and operating deflection forces into these flexure blocks, therefore, only one cylinder each is required.
ロールスタンド内において、わずか2つのシリンダーだけが、撓みブロック内への撓み力の導入のために使用されていることによって、摩擦力は、著しく低減可能である。 In the roll stand, only two cylinders are used for the introduction of the bending force into the bending block, so that the friction force can be significantly reduced.
スピンドル往復動伝動装置によって、同様に、ロールの摩滅領域も補償可能である。 The spindle reciprocating transmission can likewise compensate for the wear area of the roll.
本発明による装置は、6重式ロールスタンド内における中間ロール撓みのためにも使用可能である。同様に、可逆ロールスタンド内における使用も可能である。 The device according to the invention can also be used for intermediate roll deflection in a six-fold roll stand. Similarly, it can be used in a reversible roll stand.
本発明の更に別の有利な実施形態は、従属請求項において開示されている。 Further advantageous embodiments of the invention are disclosed in the dependent claims.
図面内において、本発明の実施例が図示されている。 In the drawings, embodiments of the invention are illustrated.

In the roll stand 1, the
撓みブロック5および5aは、ピストンシリンダー7を介して結合されており、このピストンシリンダーのピストン9が、この撓みブロック5a内において軸受けされており、これに対して、このピストンの結合ロッド8が、この撓みブロック5内において組み付けられている。これら撓みブロック5、5a、5′、および5a′は、一方ではワークロール3、3aのチョック4、4aと、他方では圧延ロールスタンド6、6′と、公知の方法で結合されている。

The rolling direction of the rolling material that passes is illustrated by a two-
本発明は、スピンドル往復動伝動装置の使用に限定されず、むしろ、垂直方向の位置決めのためのそれぞれの機構、例えば、強制案内機構有するくさび状体、クランプヘッドおよび位置検出器を有するシリンダー、または、偏心軸が起用されることも可能である。 The invention is not limited to the use of spindle reciprocating transmissions, but rather a respective mechanism for vertical positioning, for example a wedge with a forcible guide mechanism, a cylinder with a clamp head and a position detector, or It is also possible to use an eccentric shaft.
