Abstract
Способ получения изделий с криволинейными участками из профильных труб, преимущественно, прямоугольного сечения, характеризующийся тем, что, перед изгибанием заготовки видоизменяют ее поперечное сечение, предпочтительно, по всей длине, путем образования, как минимум, на двух противоположных сторонах заготовки декоративных ребер жесткости, предпочтительно, двух, на каждой стороне, посредством прокатывания вовнутрь части стенки трубы на упомянутых сторонах, при этом высоту ребра выбирают из соотношения h=(0,6-1,2)δ, предпочтительно, h=(0,8…1)δ, где: h - высота ребра, δ - толщина стенки трубы, а ширину прокатываемой части стенки трубы - из соотношения S=S-(5-7)δ, предпочтительно (5,8…6,2)δ, где: S- ширина прокатываемой части стенки трубы, S - ширина профиля трубы, δ - толщина стенки трубы, затем, как минимум, один конец, предпочтительно, оба конца заготовки, деформируют по непрокатанным сторонам и обрезают до требуемой длины, при этом в зоне реза заготовку деформируют таким образом, что декоративные ребра жесткости соприкасаются или практически соприкасаются между собой, образуя при этом прямолинейный или практически прямолинейный участок с переходными зонами от упомянутого участка к основному материалу, причем длину упомянутого прямолинейного участка выбирают из соотношения L≈l+l+l, где: L - общая длина образованного прямолинейного участка, l- длина прямолинейного участка до линии реза, l- длина прямолинейного участка после линии реза, l- ширина реза, при этом длину переходного участка выбирают из соотношения L=(3…6)S, предпочтительно, 4…5, где: S - ширина профиля трубы, после чего производят гибку по непрокатанным сторонам.A method of obtaining products with curved sections from shaped tubes, mainly of rectangular cross section, characterized in that, before bending the workpiece, its cross section is modified, preferably along the entire length, by forming at least two opposite sides of the workpiece decorative stiffeners, preferably , two, on each side, by rolling inwardly part of the pipe wall on the said sides, the rib height being selected from the relation h = (0.6-1.2) δ, preferably h = (0.8 ... 1) δ,where: h is the height of the ribs, δ is the thickness of the pipe wall, and the width of the rolled part of the pipe wall is from the relation S = S- (5-7) δ, preferably (5.8 ... 6.2) δ, where: S is the width the rolled part of the pipe wall, S is the width of the pipe profile, δ is the thickness of the pipe wall, then at least one end, preferably both ends of the workpiece, is deformed along the non-rolled sides and cut to the desired length, while in the cutting zone the workpiece is deformed in this way that the decorative stiffeners are in contact or practically in contact with each other, forming straight A straight or almost straight section with transition zones from the said section to the base material, the length of the said straight section being selected from the ratio L≈l + l + l, where: L is the total length of the formed straight section, l is the length of the straight section to the cutting line, l is the length of the straight section after the cut line, l is the width of the cut, and the length of the transition section is selected from the ratio L = (3 ... 6) S, preferably 4 ... 5, where: S is the width of the pipe profile, after which bending is performed according to untracked sides.
