FEM Simulation of Rolling-Pressing Process with Horizontal and Vertical Rolls

In this work, finite element simulation of the rolling-pressing process with horizontal and vertical rolls was carried out.To analyze the efficiency of metal processing, the main parameters of the stress-strain state were considered: equivalent strain, equivalent stress, average hydrostatic pressure, deformation force.Aluminum alloy Al6063 was chosen as the workpiece material.For variational simulation, models with a change in the heating temperature of the workpiece and the rolls rotation speed were constructed.The most optimal option is a model in which the workpiece was heated to 100 C and deformation was carried out at a circumferential speed of the first pair of rolls of 60 rpm.Variants with a single temperature reduction to 20 C, or rotation speed reduction to 35 rpm also give acceptable results to all the indicators considered.However, rotation speed reduction to 10 rpm makes it impossible to carry out a stable process at any temperature.
