Tension Between Roll To Roll Straightener Force Can Affect The Experimental Study Of Parameters

Modern roller straightening mechanism perfect and improved by scholars inthe straightening field， equipment of straightening either structure orstraightening ability has been greatly improved, especially in the press measure,force and torque model,etc. But a less study for plate internal tension effect inthe roller straightening, the situation making tension factors on forcestraightening process is not understood, the tension existing make straighteningefficiency and power output unable to get the correct theoretical guidance.Based on the metallurgical laboratory eleven roll hydraulic rollerstraightening machine experiment platform construction projects,research ondeformation characteristics in the straightening process, analysis of neutral layervelocity of each deformation of the units, obtaining the bending unit sectiontension model by different velocity, two groups of motor provide a variablespeed, research the relationship tension on the straightening process ofstraightening force, driving torque and plate shape, preliminary establishment oftension affect mathematical model in the straightening process.Through the analysis of experimental data, show plate bite process havenip, steady-state and throw-out three distinct phases plate straightening process.Under steady-state every rollers torque distribution different theoreticalcalculation. Tension working make every rollers torque distribution obviousdifference to un-tension working. Induction getting tension on straighteningforce influence, straightening process tension calculation mathematical modeland confirm the relationship of plate torque, tension and press measure.Through the experimental study by the research group, tension affect studyreveals the tension generation mechanism, existing way, distribution law andestablish rational model, the straightening process in the presence anddistribution to establish a reasonable model, summarize the impact of tension onthe parameters of force and torque, it have certain significant for rollerstraightening machine in the structure and the process o.
