Sažetak

The article deals with a new-design radial-shear rolling mill combined with pressing function. Finite element methods and MSC.SuperForge SW were used to generate quantitative data and establish basic patterns of strain-stress state (SSS) and temperature distribution during workpieces rolling-pressing in helical rollers. Formulas were derived by theoretical data approximation to allow a highly accurate determination of the SSS and temperature distribution pattern in the deformed workpiece. An equation-based mathematical model for the RSRM operation is proposed. The RSRM operation mathematical model is implemented in WinCC 7.0 and Step 7 SW using FBD and SCL PL. Sensor- derived data allow to automatically adjust the process modes of manufacture of bars and wires while avoiding any production defects.
