Изобретение относитс к обработке металлов давлением.The invention relates to the processing of metals by pressure.
Известен способ -изготовлени гнутых профилей проката путем последовательной подгибки элементов заготовки При поперечном сжатии .мест изгиба за счет сжимающих усилий , прикладываемых к полкам заготовки и за счет разглаживани тофра, предварительно образованного на заготовке.A known method is to manufacture rolled steel profiles by successively bending the workpiece elements. In transverse compression, the places of bending are due to compressive forces applied to the shelves of the workpiece and by smoothing the tofra previously formed on the workpiece.
Однако известный способ не позвол ет в р де случаев создать необходимое сжатие мест изгиба, предупредить разрушение и утонение металла в -местах изгиба, а такж;е нолучить минимальные радиусы кривизны готового издели .However, the known method does not allow in a number of cases to create the necessary compression of the bending points, to prevent the destruction and thinning of the metal in the bending places, and also to obtain the minimum curvature radii of the finished product.
Дл повышени качества профилей по предлагаемому способу перед подгибкой на заготовке -создают излишек металла в виде утолш,ени на смежных с местами изгиба на участках, а в процессе подгибки производ т обжатие утолщений ио высоте.To improve the quality of the profiles of the proposed method, before bending on the workpiece, excess metal is created in the form of thickening, on adjacent areas with bending in the areas, and in the process of bending, compression of the thickenings is made to its height.
На чертеже приведена схема формовки швеллера по предлагаемому способу, в которой 1-исходна заготовка, 2 - утолщени металла на исходной заготовке, 3 - готовое изделие.The drawing shows a scheme for forming a channel according to the inventive method, in which 1 is the initial billet, 2 is the metal thickening on the original billet, 3 is the finished product.
Исходна заготовка 1 с предварительно выполненными утолщени ми 2 последовательно фор.моизмен етс в гнутый профиль 3. ПриOriginal preform 1 with preformed thickenings 2 is successively molded into a bent profile 3. When
этом предварительно выполненное утолщение последовательно по перехода.м одновременно с подгибкой элементов заготовки раздавливаетс и вытесненный металл перемещаетс вBy this, the previously formed thickening successively along the transition. Simultaneously with the bending of the workpiece elements, the crush is crushed and the displaced metal moves to
сторону мест изгиба, создава в них поперечное сжатие .металла.side of the bend, creating in them the transverse compression of the metal.
В зависимости от прин той схемы формовки и необходимости создавать поперечное сжатие раздавливание может производитьс Depending on the adopted molding pattern and the need to create lateral compression, crushing can be done
в одио.м или нескольких проходах.in one or several passes.
Местные утолщени на заготовке могут быть выполнены различной формы ка,к с одной стороны, та,к .и с двух, и ориентированы как в иродольно.м, так и поперечном направлени х . Они могут быть получены, например способами перио.дической прокатки.Local thickenings on the workpiece can be made of a different shape, k, on the one hand, that, to and from two, and oriented both in the myrodol and transverse directions. They can be obtained, for example, by means of periodic rolling.
