    • The present invention provides means for automatically adjusting rollforming equipment to accommodate a range of different gauges of material such as sheet metal being formed. One rollforming roller (34) on each rollforming head (4A) is mounted on an eccentric so that a force supplied in the direction of material feed through the tooling rollers (33, 34) will increase the tooling gap therebetween. An automatic gauge adjustor includes applying a source of substantially constant pressure sufficient to achieve the rollforming action against rotation about the eccentric while allowing movement of the rollforming roller also about the eccentric so that the roll will move against the pressure being provided in the direction of the material feed to accommodate the gauge of material within the working range set. This allows the rollforming head (4A) toadjust the tooling gap between rollers to accommodate varying gauges automatically and with minimal or no lead in damage while the rolls adjust to the new gauge of material.
    • 本发明提供了用于自动调节辊轧设备以适应一定范围的不同量程的材料(例如形成的金属板)的装置。 每个辊轧成形头(4A)上的一个成型辊(34)安装在偏心轮上,使得沿材料供给方向供给的力通过工具辊(33,34)供应将增加它们之间的工具间隙。 自动量规调节器包括施加足够大的恒定压力源,以实现围绕偏心体的旋转的滚动成形动作,同时允许辊轧成型辊也绕偏心轮移动,使得辊将抵抗沿着 材料进料,以适应工作范围内材料的规格。 这允许辊轧成型头(4A)调整辊之间的加工间隙,以便在辊调节到新的材料规格时自动容纳变化的量规并且损伤最小或无铅。

    • The present invention has an aim of providing a rolling mill and an operation method thereof for remarkably extending a roll life, optimizing a driving source and attaining maintenance free in the rolling mill, in which an optimum ratio for the number of driving rotations between each of driving roll stands can be obtained by arranging rolls of predetermined shapes in a plurality of roll stands and adjusting the rolling reduction so as to obtain a required shape, then gripping a material to be formed completed with formation by a clamping device, drawing the same for a required length without driving all the rolls and determining the number of rotation or the like of each of roll stands, and driving force between each of driving roll stands can be matched and optimized by driving each of the driving roll stands at the optimum ratio for the number of driving rotation, which can remarkably extend the roll life, optimize the driving source and attain the maintenance free in the rolling mill.
