Abstract

Изобретение относится к обработке металлов давлением и может быть использовано для получения осесимметричных деталей, преимущественно ступенчатых валов, с поверхностными слоями методами поперечной и поперечно-клиновой прокаток. Задачей изобретения является увеличение ресурса пластичности материала, повышение производительности и снижение себестоимости производства осесимметричных деталей. Поставленная задача решается тем, что в способе изготовления осесимметричных деталей с поверхностными слоями, включающем получение первоначального центрального стержня из материала-основы и нанесение на его поверхность слоев с требуемыми свойствами, на центральный стержень последовательно монтируют одну или несколько тонкостенных втулок одна на другую из разнородных материалов с требуемыми свойствами, затем смонтированную слоистую заготовку деформируют поперечной прокаткой до получения заданной формы, и одновременно с этим поперечной прокаткой закрепляют слои из втулок на центральном стержне по поверхности их контакта; а также тем, что в процессе поперечной прокатки слои из втулок сваривают между собой и приваривают к центральному стержню кузнечной сваркой; а также тем, что прокатку осуществляют клиновыми инструментами; а также тем, что смонтированную слоистую заготовку перед прокаткой нагревают выше температуры окружающей среды, но ниже температуры плавления центрального стержня; а также тем, что наружную втулку изготавливают из менее пластичного материала по отношению к материалу-основе; а также тем, что наружную втулку изготавливают по длине короче первоначального центрального стержня и монтируют на нем в месте наибольшей эксплуатационной нагрузки осесимметричной детали; а также тем, что после поперечной прокатки детали нагревают до температуры свыше 0,6 температуры плавления материала-основы.The invention relates to the processing of metals by pressure and can be used to obtain axisymmetric parts, mainly stepped shafts, with surface layers by methods of transverse and transverse wedge rolling. The objective of the invention is to increase the resource of plasticity of the material, increase productivity and reduce the cost of production of axisymmetric parts. The problem is solved in that in a method of manufacturing axisymmetric parts with surface layers, which includes obtaining the initial central rod from the base material and applying layers with the desired properties on its surface, one or more thin-walled bushings are mounted on the central rod one from another of dissimilar materials with the required properties, then the mounted laminated billet is deformed by transverse rolling to obtain a given shape, and at the same time cross ary rolling fixed layers of the hubs on the central shaft at their contact surface; as well as the fact that during the transverse rolling, layers from the bushings are welded together and welded to the central rod by blacksmithing; as well as the fact that rolling is carried out by wedge tools; as well as the fact that the assembled laminated preform is heated before rolling above ambient temperature, but below the melting temperature of the central rod; and also the fact that the outer sleeve is made of less ductile material with respect to the base material; as well as the fact that the outer sleeve is made shorter in length than the original central rod and mounted on it in the place of the highest operational load of the axisymmetric part; and also the fact that after transverse rolling, the parts are heated to a temperature in excess of 0.6 the melting temperature of the base material.
