Abstract
Изобретение относитс к обработке металлов давлением, в частности к способам изготовлени гофрированных гнутых профилей в валках клетей профилегибочноно стана. Целью изобретени вл етс сокращение количества технологических переходов;и повышение качества профилей за счет исключени переформовок в местах изгиба. В первых проходах формуют по крайней мере три гофра трапециевидной формы с межцентровым рассто нием, равным межцентровому рассто нию между гофрами на готовом профиле. При этом межгофровьпЧ участок формуют по дуге окружности с длиной, равной длине этого участка на готовом профиле. В последующих переходах при подгиб,ке ветвей гофров дугообразный участок последовательно вьтр мл ют до I получени окончательной конфигурыции . Формирование на полосе одновре (Л менно трех гофров позвол ет уменьс шить количество формующих клетей. 1 ил.The invention relates to the processing of metals by pressure, in particular to methods for producing corrugated curved sections in rolls of rolls of a roll forming mill. The aim of the invention is to reduce the number of technological transitions, and improve the quality of the profiles by eliminating reshaping at the bend points. In the first passages, at least three trapezoidal corrugations are formed with an intercenter distance equal to the intercenter distance between the corrugations on the finished profile. In this case, the intercommunity section is formed in an arc of a circle with a length equal to the length of this section on the finished profile. In subsequent transitions during the folding, the ke of branches of the corrugations, the arcuate portion is successively centered ml until I obtain the final configuration. Formation on the strip at the same time (three triangular corrugations allow reducing the number of forming stands. 1 Il.
