Использование: производство заготовок для прокатки фасонных профилей. Цель: повышение выхода годного. Сущность изобретения: способ получения заготовок включает порезку подката на мерные заготовки, подачу в зону пресса, обжатие концевых участков в несколько этапов с формированием полок и стенки, с приложением усилий подпора к полкам и последующую прокатку до готового изделия. Новым в способе является то, что на первом этапе производят предварительное обжатие стенки концевых участков на величину ΔH, определяемую из выражения
Figure 00000001

где B - номинальная ширина полки заготовки; Hп - толщина полки; Bк - ширина полки на торце; Bб - ширина бойка; Δ - величина утяжки полки по ширине при обжатии стенки, а на втором формируют полки шириной не менее B+Δ. 1 ил.Use: manufacture of blanks for rolling shaped profiles. Goal: increase yield. The inventive method for producing blanks includes cutting a treadmill into dimensional blanks, feeding into the press zone, crimping the end sections in several stages with the formation of shelves and walls, applying pressure to the shelves and subsequent rolling to the finished product. A new method is that in the first stage, the wall of the end sections is pre-compressed by ΔH, determined from the expression
Figure 00000001

where B is the nominal width of the blank shelf; H p - shelf thickness; B to - the width of the shelf at the end; B b - striker width; Δ is the width of the shelf extension when the wall is compressed, and on the second one forms shelves with a width of at least B + Δ. 1 il.
