Изобретение относитс  к обработке металлов давлением и может быть использовано в машиностроительной, авиационной и других отрасл х промышленности при производстве высокоточных листовых деталей .The invention relates to the processing of metals by pressure and can be used in the engineering, aviation and other industries of the industry in the manufacture of high-precision sheet metal parts.

Известен способ изготовлени  изогнутых профилей путем вырезки листовой заготовки , последующего формообразовани  .A known method of making curved profiles by cutting sheet metal, followed by shaping.

Этот способ не обеспечивает получение высококачественных деталей. Кроме того, способ характеризуетс  высокой трудоемкостью и низким коэффициентом использовани  материала.This method does not provide high-quality parts. In addition, the method is characterized by high labor intensity and low material utilization.

Низкое качество деталей, изготовленных описанным выше методом, обуславливаетс  неравномерным утонением материала по сечению детали. Изгиб на ребро полки сопровождаетс  утонением материала в одном месте и образованием складок в другом .The poor quality of the parts manufactured by the method described above is due to the uneven thinning of the material over the section of the part. Bending to the flange of the shelf is accompanied by thinning of the material in one place and the formation of folds in another.

Наиболее близким решением к данному  вл етс  способ изготовлени  пространственных деталей нз листовой заготовки путем предварительного образовани  на периферии гофров, каждый в форме фигуры с поверхностью второго пор дка, например эллиптического параболоида, мала  ось которого перпендикул рна плоскости заготовки , и формовки с разглаживанием гофров 2.The closest solution to this is a method of making spatial details on the sheet blank by pre-forming corrugations at the periphery, each in the form of a figure with a second-order surface, for example, an elliptical paraboloid whose small axis is perpendicular to the plane of the blank, and forming with smoothing of the corrugations 2.

Этот снособ позвол ет получать более качественные детали за счет уменьшени This tool allows you to get better parts by reducing

утонени , но не обеспечивает изготовлени  профилей с переменной кривизной.thinning, but does not provide for the manufacture of profiles with variable curvature.

Целью изобретени   вл етс  получение деталей тина швеллера с участками разной кривизны.The aim of the invention is to obtain details of channel tin with areas of different curvature.

Это достигаетс  тем, что одновременно с формовкой осуществл ют П-образную гибку , а гофры выполн ют посредством местного раст жени  с размещением вершины каждого из них на уровне линии гиба полок и с расположением оси параболоида перпендикул рно линии гиба в плоскости, раздел ющей участки разной кривизны, изготавливаемого щвеллера, при этом соотношение длин больших полуосей эллипсаThis is achieved by simultaneously with forming forming a U-shaped bending, and the corrugations are performed by local stretching, placing the top of each of them at the level of the bending line of the shelves and placing the axis of the paraboloid perpendicular to the bend line in the plane separating different parts curvature produced by the channel, while the ratio of the lengths of the major semiaxes of the ellipse

берут равным отношению длин дуг кромки нолки на участках с разной кривизной.take equal to the ratio of the lengths of the arcs of the edges of the soles in areas with different curvature.

На фиг. 1-2 показана листова  заготовка с предварительно отштампованными гофрами; на фиг. 3-4 - отштампованна FIG. 1-2 shows a sheet blank with pre-stamped corrugations; in fig. 3-4 - stamped

Способ осуществл етс  следующим образом .The method is carried out as follows.

Из листа вырезают плоскую заготовку с требуемым наружным контуром, а затем вA flat blank with the required outer contour is cut out of the sheet, and then in
