The Design Of Flattening Machine And The Parameters Reseatch Of Heavy Plate Flattening

With the development of society, our country’s downstream industries on the platequality requirements increase and wide plate, especial plate demand more. From thecurrent situation, our country is a third heavy plate mill construction climax, and thequality, specifications of plate especially more high requirements of flatness. Theflattening machine is the main equipment of super thick plate correction, productionworkshop heat treatment production line and the demand is also further increase. Fordifferent plate leveler have different stress and conditions, these data can effectivelyimprove the efficiency of plate straightening, a great impetus to industrial production.This paper analysised the deformation, bending moment and the distribution of stressin the process of straightening with the existing elastic-plastic theory, combined with theexisting straightening theory, and determined the reasonable parameters of pressure(pressure determines the spacing, press pad bending deflection, flattening machine etc),and the establishment of the finite element analysis flat model.Solidworks simulation using the analysis of stress and strain of analysising the framecan work normally at the preload condition and get the maximum of nut displacement.Simulating the model for different operating conditions (plate thickness, width, initialdeflection, pivot spacing, material properties) by making full use of the Abaqus finiteelement analysis method. By analyzing plate flatness get different conditions on theanti-bending deflection and calculate the formula-bending deflection.The formula-bending deflection is used to calculate the steel material is45steel, theinitial deflection of50mm,1140mm steel pivot pitch-bending deflection.It uses flattenflatten model analysis to verify the anti-bending deflection calculation formula accuracy.To improve the efficiency of flattened steel, the resulting formula is programmedwith VB.It gets the control panel for anti-bending deflection, and enters the values of theparameters to get the anti-bending deflection.
