The invention discloses a steel plate straightening machine with multiple roller distances, high rigidity and high load, which comprises a prestressed interlocking frame. The prestressed interlocking frame includes a lower base frame arranged on the ground, and four The vertically arranged hollow column is connected with two upper beams, the lower base frame and the hollow column, and the upper beam and the hollow column are equipped with interlocking mechanisms, and the hollow column is equipped with a tensioning prestressing mechanism; the lower base frame is connected with a horizontal The lower roller system device is arranged, and the upper beam is connected with the upper roller system device opposite to the lower roller system device. The invention is applied in the field of medium and thick plate straightening, and has the characteristics of high rigidity interlocking frame, side roll belt load adjustment, online roll gap adjustment, compact structure, fast response, high-speed roll change of multi-roll system, etc., and can realize reciprocating straightening Straight, good straightening plate shape, especially can meet the straightening flatness requirements of high-strength steel plates with a large thickness range.
Description
technical field [0001] The invention belongs to the field of mechanical equipment, and further relates to a mechanical equipment for cold treatment of metal profiles, in particular to a multi-gap, high-rigidity, and high-load steel plate straightening machine. Background technique [0002] The straightening machine is one of the main finishing equipment on the medium and heavy plate production line, which is used to straighten the steel plate to make its flatness meet the national standard and customer's requirements. In order to improve the plate shape and improve product quality, modern straightening machines adopt various technologies and means. [0003] During the production process of the straightening machine, as the thickness of the straightened steel plate continues to increase, the yield strength of the straightened steel continues to increase, and the required straightening force increases geometrically; all the straightening force of the straightening machine must...
