Ьыпр мл ёмых, предварйтельнб изогйутых йдЬскйх участков.For the first half of the previous plots.
Кроме того криволинейные участки обжимаютс в радиальном наиравлении (по толщине ) в рабочих калибрах валков (фиг. 3) под действием давлений Р, возникающих в св зи с тем, что толщина заготовки 5о больще размера калибра 5.In addition, the curved sections are crimped in radial width (thickness) in the working caliber of the rolls (Fig. 3) under the action of pressures P, arising from the fact that the thickness of the workpiece 5 o is larger than the size of the caliber 5.
Обжатие мест изгиба профил в радиальном направлении позвол ет исключить поверхностные дефекты и получить минимальные радиусы изгиба за счет создани подпора металла Q (фиг. 3) в поперечном направлении, получаемом при выпр млении плоских участков и вытеснении металла из мест изгиба на смежные участки.Compressing the profile bending points in the radial direction allows eliminating surface defects and obtaining minimum bending radii by creating a backwater of the metal Q (Fig. 3) in the transverse direction obtained by flattening out the flat sections and displacing the metal from the bending points to adjacent areas.
Форму ла изобретени Form la invention
Способ производства гнутых профилей, преимущественно из металлов с низкими пластическими свойствами, включающий последовательную формовку профил с получением криволинейного сечени заготовки и выпр мление ранее изогнутых плоских участков при одновременном увеличении кривизны мест изгиба за счет тангенциального и радиального сжати , отличающийс тем, что, с целью получени профилей с минимальными радиусами изгиба, в процессе увеличени кривизны мест изгиба, одновременно со сжатием осуществл ют вытеснение металла из мест изгиба на смежные с ними участки.A method of producing curved profiles, mainly from metals with low plastic properties, including sequential profile molding with obtaining a curvilinear cross section of the workpiece and straightening previously bent flat sections while simultaneously increasing the curvature of the bending points due to tangential and radial compression, profiles with minimum bending radii, in the process of increasing the curvature of the bend points, simultaneously with compression, the metal is displaced from the bend points on adjacent plots with them.
