本発明は平鋼の横曲り（以下キャンバ）の修正の向上に
好適な矯正機に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a straightening machine suitable for improving the correction of horizontal bending (hereinafter referred to as camber) of flat steel.
従来の矯正機では、第２図、第３図に示すように、キャ
ンハラ修正するため、ローラの鍔部で圧下を板幅方向に
与えると次のような欠点があった。As shown in FIGS. 2 and 3, conventional straightening machines have the following drawbacks when rolling down is applied in the width direction of the sheet using the flange of the roller in order to correct challah.
（１）平鋼にネジレが発生する。(1) Twisting occurs in the flat steel.
（２）平鋼の長手方向に対して、ヘビー状に反りが発生
する。(2) Heavy warping occurs in the longitudinal direction of the flat steel.
本発明の目的は、平鋼のキャンバを確実に修正する矯正
機を提供することにある。An object of the present invention is to provide a straightening machine that reliably corrects the camber of flat steel.
本発明は、千鳥状に配置した複数のローラからなる下ロ
ーラを平鋼のキャンバの量に応じてローラの操作側、駆
動側の圧下量を調整出来るようにしたことを特徴とする
。The present invention is characterized in that the lower roller, which is made up of a plurality of rollers arranged in a staggered manner, can adjust the amount of rolling on the operation side and drive side of the lower roller according to the amount of camber of the flat steel.
本発明は、例えば、操作側を強圧下、駆動側を軽圧下に
すれば、その部分を通る平鋼の道程に伸び差が出来る。In the present invention, for example, if the operation side is subjected to strong compression and the driving side is subjected to light compression, a difference in elongation will be created in the path of the flat steel passing through that part.
従って、平鋼のキャンバの量に対する圧下量を調整する
ことにより、前記目的を達成するようにしたものである
。Therefore, the above object is achieved by adjusting the amount of reduction relative to the amount of camber of the flat steel.
本発明の一実施例を図面によって説明する。 An embodiment of the present invention will be described with reference to the drawings.
第１図は、ローラの配置を示す。下ローラの圧下量が操
作側、駆動側と調整出来る。このローラ１の圧下量に変
差を与えると、その圧下差がすべて伸びの差（円弧状の
曲がり）として現れる。FIG. 1 shows the arrangement of the rollers. The amount of reduction of the lower roller can be adjusted on the operation side and drive side. When a variation is given to the amount of reduction of this roller 1, the difference in reduction appears as a difference in elongation (arc-shaped bending).
キャンバの発生は、平鋼２の幅方向での伸びの不均一に
よるものである。従って、この伸び差相当の圧下変差を
与えればキャンバは修正することが出来、平坦度が向上
する。The occurrence of camber is due to non-uniform elongation of the flat steel 2 in the width direction. Therefore, by applying a reduction change equivalent to this difference in elongation, the camber can be corrected and the flatness can be improved.
本発明によれば、キャンバが容易に修正出来、平坦度が
向上する。According to the present invention, camber can be easily corrected and flatness can be improved.

る平鋼矯正機。1. In a straightening machine in which a plurality of flanged inclined rollers are arranged in a staggered manner and the flat steel is flattened by repeatedly bending between the flanged inclined rollers, the lower roller is used to flatten the camber of the flat steel. the operation side of the flanged inclined roller according to the amount;
A flat steel straightening machine characterized by being able to adjust the rolling reduction amount on the drive side.
