где α - суммарный угол подгибки в последней паре валков, град;
E и σт - соответственно величины модуля упругости и предела текучести материала заготовки, МПа;
l - длина участка изгиба профиля, мм.The method of profiling equal-angled corners, which consists in sequentially bending at given angles of the strip billet elements by pairs of rolls with predetermined rolling diameters while simultaneously bending the formable strip, characterized in that when profiling corners with a thickness of 0.5. ..2.0 mm with a shelf width of b ≤ 40 mm, the profile is bent in the vertical plane between the last and penultimate pairs of rolls by reducing the rolling diameter at the lower roll and increasing it at the upper roll of the last pair by
where α is the total bending angle in the last pair of rolls, deg;
E and σ t - respectively, the elastic modulus and yield strength of the workpiece material, MPa;
l is the length of the profile bending section, mm.
