Deformation And Energy Parameters Research Of Typical Cross-section Of Roll Forming

Roll forming has a very important position in the field of sheet forming, it is an production process of economical, environmentally friendly, energy-saving and has strong vitality. In order to be able to produce various sorts and varieties of high-quality roll forming products, we should continuously improve and refine roll forming process, this is necessary to research the relevant parameters in the roll forming process, furthermore, R&D roll forming equipment also should clearly know the relevant parameters, such as the bending angle, bending radius, deformation length, forming moment and forming force and so on. However, at present it is has very little research about this at home and abroad, especially it has less research about the roll forming force and moment parameters in the forming process.In this article, it review the practical application and theoretical research status of the roll forming, through the learning of roll forming relevant literature in home and abroad. Emphasis on force and energy parameters research of roll forming. Based on theoretical assumptions, the geometric model is simplified, deduced the total deformation power in the roll forming process, the bending angle calculation expression and its vertical distribution map has been calculated, parse out the formula of the deformation length, forming moment and the forming force, and analysis of the influencing factors.In order to verify the correctness of the force and power parameters, in this article carried out the roll forming force and energy simulation experiments. Based on orthogonal experiment design the experiment scheme, do a series of simulation experiments about the different levels of the different factors, obtain the simulation values. Through the comparative analysis of the calculated values and simulation values, it proved the correctness of the theoretical derivation of the formula.In this article, through theoretical analysis and simulation, obtained the calculation expression of force and energy parameters of roll forming, can provide theoretical reference for roll forming theoretical research, product design and manufacturing.
