Straightening Technology Based on Displacement Control

Current mathematical model of straightening technology is based on the pressure control, which is difficult to apply to real production. A new mathematical model of straightening technology based on the displacement control is conducted. An equation involving the elastic zone ratio, the force parameter and the strain ratio relation is generated based on the influence of the elastic zone ratio during the precise straightening process. A further calculation methodology for straightening displacement is also introduced. This methodology is effective to the straightening parameter calculation on shafts and has been proven by experiments. It can also guide the precise straightening press design and manufacturing to some extend.
