The Accident Analysis And Transformation Study On The Stretcher Straightener

The stretcher straighter is a important equipment which levels a board of strip. Along with the development of industry, the requirement of the thin strip of high strength and material of stainless steel extremely increase day by day, The requisition on panel flatness improves year by year too at the same time. Straightening roll, because their structure and the limitations of the leveling technology, is nearly unable to level high strength alloy steel with material 3D shape defects( wave of edge shape and middle flesh dipper shape,etc.s). While levelling the defect of 3D shape of the strip, should make the strip produce plasticity to extend. IF use the continual stretcher slaughterers, can present the following problem in succession: 1) Drawing it while levelling in succession, needing makes the strip produce the stress which exceeds limit that the material surrenders, To the relatively thick and relatively wide alloy steel strip, must exert very great tension, this will consume very great energy; 2)When finishing levelling fragility material, Apt to take brokenly, this will cause the accident of the equipment.This text discuss and make essential parameter calculate for stretcher strengtheners by principle; Analyses and research and propose transforming schemes to its main trouble. Focal point at the ratio of transmission calculating, every gear wheel torsion of the differential gear wheel system distributing and the Accident analysis and scheme of transforming for the stretcher straightener, We have carried on the detailed discussion to study. According to measuring actually and theory result, analyse from mechanics, bearing capacity emulation is calculated and thinks that the following is the main reason of the trouble: System assault or difference transfer load speed lead to the fact; The gear wheel loses efficiency; Impact on tension increment of quantity under the crooked roller and the levelling roller; Change of the strip specification, etc.. To these reasons, transform schemes in order to solve these problems completely after putting forward some. The research of this text has carried on the detailed exposition in principle of stretcher strengtheners, Have put forward a set of concrete, comparatively overall analysis to the trouble of the equipment, And has offered the theory foundation and real solution.
