Р1зобретение относитс к обработке металлов давлением, в частности к производству гнутых профилей проката.The invention relates to the processing of metals by pressure, in particular to the production of curved rolled sections.
Известен способ производства гнутых профилей , при котором заготовка последовательно формоизмел етс щ готовый профиль в валка .х стана.There is a known method for the production of curved profiles, in which the billet sequentially molds the finished profile into a roll of the mill.
Однако этот способ не обеспечивает требуемой точности заз01ра между кромками, необходимой кривизны .в местах изгиба, приводит к значительному утонению металла криволинейных участков.However, this method does not provide the required accuracy of the gap between the edges, the required curvature. At the places of bending, leads to a significant thinning of the metal of the curvilinear sections.
Целью изобретени вл етс обеспечение стабильности геометрических размеров профил .The aim of the invention is to ensure the stability of the geometric dimensions of the profile.
С этой целью иа первых переходах полосе придают желобчатую форму, а на последуюШ .ИХ - получеиную заготовку осаживают вокруг оправки до получени требуемой формы поперечного сечени .For this purpose, the first passages of the strip are given a grooved shape, and on the subsequent .THEIR - the half-finished billet is deposited around the mandrel to obtain the desired cross-sectional shape.
CyaiHOCTb изобретени по сн етс чертежом , где показаны технологические переходы получени полузамкнутого профил .The cyaiHOCTb of the invention is illustrated in the drawing, which shows the technological transitions to obtain a semi-closed profile.
Изготовление профил по предложенному способу осуществл етс за меньшее число технологических переходов, чем по из вестному, в св зи с предварительной отформовкой желоба ло сравнительно жесткому 1режиму формообразовани (I-IX переходы). В последующих X и XI переходах, примен осадку же2The production of the profile according to the proposed method is carried out in a smaller number of technological transitions than in the known, due to the preforming of the groove in the relatively hard forming mode (I-IX transitions). In the next X and XI transitions, using the same draft 2
лобчатой заготовки на оправке, производ т отформовку мест изгиба путем их искривлени с од 1овременным поперечным сжатием. При этом пр молинейные участки профил , постепенно выпр мл сь с помощью оправки, упираютс в элемент валков и оправки и строго фиксируютс по ширине.frontal workpieces on the mandrel, bend the places of bending by their curvature with a single transverse compression. In this case, the straight profile sections, which are gradually straightened with the help of a mandrel, abut against the element of rolls and mandrels and are strictly fixed in width.
Отклонени в размере ширины исходной заготовки существенным образом сказываютс не на линейных размерах профил , а на степени поперечного сжати элементов формуемого профил п толщине металла в местах изгиба.Deviations in the size of the width of the original billet have a significant effect not on the linear dimensions of the profile, but on the degree of lateral compression of the elements of the molded profile and thickness of the metal at the bend points.
Предлагаемый способ позвол ет изготовить полузамкнутые и замкнутые профили с размерами поБып1енной точности.The proposed method makes it possible to manufacture semi-closed and closed profiles with dimensions of perfect accuracy.
Предмет изобретени Subject invention
Способ производства гнутых профилей, преимущественно полузамкнутых, путем последовательного формообразовани из полосы в валках, отличающийс тем, что, с целью обеспече1Н1 стабильности геометрических размеров профил , на первых переходах полосе придают желобчатую форму, а на последующих- полученную за готовку осаживают вокруг оправки до получени лребуемой формы поперечного сечени .The method of producing curved profiles, predominantly semi-closed, by successively forming from a strip in rolls, characterized in that, in order to ensure the stability of the geometric dimensions of the profile, at the first transitions the strip is given a grooved shape, and in the following, the prepared preparation is deposited around the mandrel until the desired cross-sectional shapes.
