Claims (1)

Способ изготовления деталей знакопеременной кривизны, заключающийся в разметке исходной заготовки, ее размещении и фиксации в формующих валках, изгибе заготовки методом гибки-прокатки на валковых гибочных машинах с промежуточным поворачиванием заготовки в вертикальной плоскости и повторным заведением ее в валки, отличающийся тем, что определяются величины деформации и устанавливаются параметры настройки, обеспечивающие гибку-прокатку участков с кривизной одного знака без разведения рабочего инструмента, плавное перемещение нажимного валка на участке сопряжения криволинейного участка с прямолинейным с одновременной прерывистой протяжкой заготовки между деформирующими валками по установленным параметрам и отсутствие проскальзывания валков относительно заготовки при установившемся процессе гибки-прокатки, когда перемещение заготовки между деформирующими валками происходит только за счет сил трения качения.A method of manufacturing parts of alternating curvature, which consists in marking the initial billet, placing it and fixing it in the forming rolls, bending the billet by bending-rolling on roll bending machines with intermediate rotation of the billet in a vertical plane and re-inserting it into rolls, characterized in that the values are determined deformations and settings are set that provide bending-rolling of sections with the curvature of one sign without diluting the working tool, smooth movement of of the roll at the interface between the curved section and the straight section with simultaneous intermittent broaching of the workpiece between the deforming rolls according to the set parameters and the absence of slippage of the rolls relative to the workpiece during the steady bending-rolling process, when the movement of the workpiece between deforming rolls occurs only due to rolling friction forces.
