Abstract
Изобретение относитс к обработке металлов давлением и предназначено дл использовани при формовке в валках деталей гнутых профилей проката, преимущественно типа швеллеров с посто нной высотой полки, состо щих из крайних участков с широкой и узкой стенками посто нной ширины и среднего участка со стенкой переменной ширины. Цель изобретени - повышение качества профилей за счет исключени их переформовок и заклинивани элементов валков при их аксиальном перемещении в процессе формовки . В процессе формовки профилей при юс задаче узким концом 2 в валки одновременно с приложением усилий формовки к подгибаемым полкам 7 прикладывают поперечные усили сдвига со стороны внутренней поверхности мест 8 изгиба . Поперечные усили сдвига прикладывают через расчетный промежуток времени, отсчитываемьй от момента про-д хождени через осевую плоскость вал ков сечени Б-Б, вл ющегос переходным от участка 2 к участку 3. 5 ил. (ЛThe invention relates to the processing of metals by pressure and is intended for use in forming in rolls of parts of rolled sections of bends, mainly of channel type with a constant height of the flange, consisting of extreme sections with wide and narrow walls of a constant width and an average section with a wall of variable width. The purpose of the invention is to improve the quality of the profiles by eliminating their reshaping and jamming of the roll elements during their axial movement during the molding process. In the process of forming profiles for the Yus task, a narrow end 2 rolls simultaneously with the application of forming forces to transverse the shelves 7 apply transverse shear forces from the inner surface of the bend seats 8. Transverse shear forces are applied after a calculated period of time, counted from the moment of passage through the axial plane of the rolls of section BB, which is transitional from section 2 to section 3. 5 Il.
