На основе анализа известных способов разделения пруткового сортамента на мерные заготовки установлено, что наиболее эффективным является процесс поперечно-винтовой прокатки с предварительным нанесением на пруток кольцеобразной клиновидного сечения канавки. С целью уменьшения ее глубины предложено в процессе прокатки смещать отделяемую часть материала в плоскости, перпендикулярной оси прутка на величину пластического смятия, характерного для штамповой разрезки сортамента. Based on the analysis of the known methods of separation of the bar stock into cut-to-length sections, it has been found that the most effective is the process of transverse screw rolling with the preliminary application of a ring-shaped wedge-shaped groove to the bar. In order to reduce its depth, it is proposed during the rolling process to displace the separated part of the material in a plane perpendicular to the axis of the rod by the amount of plastic crushing characteristic for the stamp cutting of the assortment.
