“…[3][4][5][6] proposed an approach to establishing a theoretical straightening model by controlling stroke, which is a key factor of the straightening stroke accuracy calculation. Generally, the straightening stroke can be calculated by the theory of elastic-plastic, FEM or empirical formula [7][8][9][10][11] . But all of them have their limitations.…”

The straightening technics is one of important means to improve the straightness of metal bar. A novel way of predicting the straightening stroke is proposed based on mathematical methods and bending experimental and numerical simulation. The experimental and numerical simulation is conducted by following the mathematical load-stroke model of press straightening process under the elastic-plastic theory. For the linear guide rails, as an example, the stroke-deflection model focusing on the straightening stroke prediction can be achieved by contrasting and integrating the bending experimental results and finite element methods (FEM) simulation data. And then the formula for predicting the straightening stroke is presented based on the precise straightening stroke-deflection model. The stroke prediction formula with high precision can be applied to the straightening stroke prediction in the high straightness metal bar manufacturing process and automatic straightening machine conveniently
