Research and simulation of the sheet leveling machine manufacturing capabilities

One of the main tasks to determine technological settings sheet leveling machine (leveler) is identify maximum roll overlap. In well-known works on study metal-roll leveling, overlaps are set basis experimental data, which applicable for sheets from material with 800-MPa yield strength. But materials a higher strength, additional research required. The purpose this work establish criteria affecting allowable overlap working rolls by leveler and dependencies most rational adjustment. When solving tasks, developed authors, an analytical mathematical model process was used as objective function that allows energy-power characteristics curvature after depending individual rolls. Within framework studies, algorithm necessary correcting longitudinal comes down determining aligning coordinates each movable known metal being processed, geometric parameters, permissible value residual leveling. consequence studying influence setup quality during multi-roll machine, laws positioning were established. linear sinusoidal identified optimal ones. Boundary factors also established These included condition pickup Using example implementing finite element at NKMZ (Ukraine), it found has dominant when thickness less than 6 mm, larger thicknesses strength prevailing. With decrease in or width sheets, ratio will be redistributed toward condition.
