Description
Изобретение относитс к обработке металлов давлением и может быть ис , пользовано при изготовлении колес и заготовок шестерен. Известен способ изготовлени осесимметричных изделий типа колес со ступицей и ободом, включающий нагрев заготовки, предварительную штамповку и прокатку Dl. Известный способ не обеспечивает получени изделий требуемого .качества при минимальных габаритах ступицы из-за ликвационной структурной неоднородности центральной части слитка. Кроме того, большие штам-повые уклоны на внутренней поверхности Ьбода привод т к излишнемуiрасходу металла Цель изобретени - повышение качества получаемых изделий и сниж.ение расхода металла за счет устранени неоднородности структуры и уменьшени штамповых уклонов. Указанна цель достигаетс тем, что в способе изготовлени осесимметричных изделий типа колес со ступицей и ободом, включающем нагрев заготовки, предварительную штамповку. и прокатку, при предварительной штамповке и прокатке получают заготовку с диаметром отверсти ступицы 0 DO +(0,8-1,3)DO и шириной обода Н HO+ (0,1-0,2)Но, где Н диаметр отверсти ступицы и ширина обода заготовки; DO и Но - диаметр отверсти ступицы и ширина обода готового издели , после чего полученную заготовку подвергают осадке с обжимом до получени окончательных размеров. На фиг. 1 показана промежуточна заготовка; на фиг. 2 - готовое, изделие .. Способ осуществл етс в следующей последовательности. Исходную заготовку нагревают, затем осаживают, штампуют и прокатыThe invention relates to the processing of metals by pressure and can be used in the manufacture of wheels and gear blanks. A known method of manufacturing axisymmetric products such as wheels with a hub and a rim, including heating the workpiece, pre-stamping and rolling Dl. The known method does not ensure the production of products of the required quality with minimum dimensions of the hub due to segregation structural heterogeneity of the central part of the ingot. In addition, large strain biases on the inner surface of bbod lead to unnecessary metal consumption. The purpose of the invention is to improve the quality of the products obtained and reduce the metal consumption by eliminating heterogeneous structure and reducing die gradients. This goal is achieved by the fact that in the method of manufacturing axisymmetric products such as wheels with a hub and a rim, including heating of the workpiece, pre-stamping. and rolling, with preliminary punching and rolling, a billet is obtained with a hub opening diameter of 0 DO + (0.8-1.3) DO and a rim width H HO + (0.1-0.2) But, where H is the hub bore diameter and width rim of the workpiece; DO and Ho are the diameter of the hole in the hub and the width of the rim of the finished product, after which the resulting billet is crimped until the final dimensions are obtained. FIG. 1 shows an intermediate blank; in fig. 2 - finished product. The method is carried out in the following sequence. The original billet is heated, then upset, stamped and rolled
